FOREWORDto the third edition
The BCSA Contractual Handbook has been comprehensively re-worked to reflect the torrent of
changes that have affected construction over the years since the second edit ion was produced.
As migh t have been ant icipated, there have been considerable developments in case law sin ce the last
edition which have affected the position of steelwork and other specialist contractors. More surprising
has been th e impact of statute notably the H ousing Grant s Construction and Regeneration Act 1996
which contains one of the few pieces of legislation specifically designed for the construction industry.
The Commercial D ebts (Interest) Act 1998, the Contracts (Right s of Third P art ies) Act 1999, the
Competition Act 1998 and th e Human Right s Act 1998 will n o doubt all make their mark in time.
Thanks are due to Roger Button and Ray White of Eversheds who produced this edition, and to
L indy P atterson of MacRoberts for contributing Ch apter 23, Scottish F orms of Contract.
The law is up to date as at 1 January 2001, although later changes have been incorporated where
possible.

Formation of Contracts
Chapter 1 1
CHAPTER 1
FORMATION OF CONTRACTS
A contract is an agreement between t wo part ies which is legally enforceable.
Elements of a Binding Contract
There are five essential elements which must exist to form a b inding cont ract.
1. Intent
All parties must intend to create a legally bin ding obligation between th em.
2. Capacity
All of the parties to a contract should be capable of entering into a legally enforceable relationship.
In corporated bodies, partnerships and individ uals (provided they are not infants or insane) all have
capacity to enter into a contract. If one or more parties lack the capacity to enter into a contract, it
may not be enforceable.
3. Agreement
Agreement is the fundamental characteristic of a contract . In order to decide whether an agreement
exists, the Courts w ill consider the relationship between t he parties objectively and look, amongstother things, to see if there has been an offer by one party and an unconditional acceptance of that
offer by the other.
4. Reasonable Certainty of Terms
The terms of the contract must be reasonably certain. It is not necessary to have resolved every
detail, but there must be general agreement, and the parties must intend to create a bind ing agreement
despite any details which remain to be agreed. For example, on a cont ract let on a With Approximate
Quant ities basis the precise amount of work required will n ot be known, but this does not prevent
a binding contract from being formed.
5. Consideration
With the exception of contracts executed as deeds (dealt w ith in more detail later in this Chapter),
there must be consideration . Consideration is wh at one party agrees to do (or not to do) to secure
something from the other party. It was defined by the House of L ords in the case of Dunlop v
Selfridge (1915)as, an act or forbearance of one party, or the promise thereof, the price for which
the promise of the other is bought...
In construction contracts the consideration is normally the promise of the contractor (or subcontractor)
to provide work and m aterials, and the promise of the Employer (or main cont ractor) to pay a sum of
money in return.
Consideration i s not essential in contracts governed by Scots law

Formation of Contracts
2 Chapter 1
There is no general legal requirement for a contract to be writ ten except for contracts of guarantee
and certain t ransactions regarding land . Although an oral agreement can be legally bind ing, written
evidence of the terms of a contract is of tremendous practical significance, because it can be very
difficult to prove the terms of an oral agreement if a dispute arises.
Offer and Acceptance
Invitation to Treat
Invitations to tender for work may be preceded by an enquiry to ascertain whether contractors are
prepared to t ender or by a formal pre-qualification process. Often these preliminary procedures take
place many months before the actual invitation to tender is issued. Usually response to such enquiries
or participation in pre-qualification processes would not impose any legally bindin g commitment on
a Steelwork Contractor to enter into a contract.
Such enquiries and processes would normally be regarded as invitations to treat, which means they
are simply an invitation to enter into negotiation. Provision of catalogues and price lists are also
invitations to treat, and do not normally bind the supplier or the recipient to enter into a contract or
to buy or sell products at a particular price.
There have, however, been exceptional cases where an actual invita tion to t ender amounts t o an offer
because the party issuing the invitation binds itself to accepting, for example, the lowest tender
(Harvela Investments Ltd v. Royal Trust Co of Canada (CI) Ltd (1986)). In such circumstances,
by entering a tender a contractor may be accepting the offer and a contract could result.
Offer
Tenders, estimates and q uotation s are all capable of being offers. Pr icing in formation given to main
contractors and clients for budget purposes may also be an offer if the information is sufficiently
detailed to form the basis of a binding contract if accepted. This is because the law will look at the
content ofany document to determine its nature, and although the title given to it, e.g. budget
price or pricing information will be relevant, it will not be decisive.
If a Steelwork Contractor wishes to give a budget price but does not w ish to be bound by it, it would
be sensible to include a statement in t he document such as:
This information i s given for budget purposes only. It does not constit ute an offer to carry outthe work or provide the materials described, and we will not be bound by it . A tender price will
be provided on request.
An offer can be made to a specific person or company, or it can be made at large . In the first case the
offer can only be accepted by the person to whom it is addressed, but an offer at large may be
accepted by any person. A tender for a main contract will usually be an offer made to a specific person
or company and can only be accepted by th at person or company. Similarly, a tender for a domestic
sub-contract will usually be made to a specific main contractor an d can only be accepted by the main
contractor.
H owever, when a company t enders to a client or his professional adviser for a n ominated or namedsub-contract , the offer may be at large and i f so, could be taken up by whomever the client appoints
as main contractor. This is important for St eelwork Cont ractors because they are an early trad e on
most projects and often the identity of the main contractor will not be known when they submit
their tenders for nominated or named sub-contracts. Unless the Steelwork Contractor qualifies his
8/10/2019 BCSA Contractual Handbook
10/245
Formation of Contracts
Chapter 1 3
tender to the effect t hat he reserves the right to withdraw it (or to revise his price) ifa main contractor
unacceptable to him is appointed, he runs the risk of his tender at large being accepted by w homever
the client appoints as main cont ractor. That may be contrary to the interests of the Steelwork
Contractor if the main contractor is not credit worthy or has a poor payment record.
Qualified Tenders
In vitat ions to tender frequently at tempt to prevent the tenderer from attaching any q ualifications to
his tender. For example, all of t he standard forms of tender produced by the Join t C ontract s Tribunal
state that the sub-contractors tender must be in accordance with the information set out in the
invitation.
The client can determine the requirements which tenders for work must meet and he can dismiss
any t enders which are qualif ied and th erefore not in accordance with his requirements. On t he other
hand, the invitation to tender documents may have omitted some important information, or lack
clarity or may insist upon onerous condit ions. In such cases, th e tenderer must make the commercial
decision as to whether to q ualify his tender.
When tendering to the client or his professional adviser on a JCT standard form of tender, the only
difficulties which should arise from the invitation to tender are either a lack of information or an
ambiguity or conflict in the details given. In these circumstances. the tenderer should inform the
client (or wh oever issued the documents), and request that the information or clarification required
be provided and issued t o all t enderers.
If there is a risk of being unable to obtain adequate supplies of steel to meet contract completion
dates, qualification may be appropriate.
H owever, tenderers should bear in mind that qualification may result in their tender being rejected
by the client.
Withdrawal of Tenders
A tender may generally be withdraw n at an y time before it is accepted, notwithstandin g any statement
or undertaking to hold the tender open for acceptance for a certain period. Even where such
undertakings are signed by the tenderer, th ey are not usually legally enforceable as contracts under
English law. (They may, however, be enforceable under Scottish law).
One situation in which they will be enforceable is where the tenderer is paid for holding th e tender
open for a specified period (this is known as an option). The option may in some cases be backed up
by a bid bond which the client can call if the tender is withdrawn d uring th e specified period.
Steelwork Contractors should also take into account the commercial implications of withdrawing a
tender. These may include that Steelwork Contractor not being invited to tender for further work
for that client.
There may also be a technical difficulty with t he withd rawal of tenders. Under English and Scots law
an acceptance is sometimes bind ing as soon as it is posted, whereas the revocation of an offer must
normally be actually brought to the knowledge of the other party before it t akes effect. A tender may
therefore have been accepted before the tenderer is aware of the fact, and if this is the case any
subsequent att empt to withdraw the tender will not be successful.
Tenders which are held open for acceptance for a fixed period will automatically lapse on expiry of
tha t period and t hereafter cannot be accepted without the agreement of th e tenderer. Some standard
forms of tender give the tenderer the opportunity to state a period after which the tender is

11/245
Formation of Contracts
4 Chapter 1
automat ically wi thd rawn . Tenderers should fill in a realistic period aft er which they would prefer to
review their price or their ability to carry out the contract.
AcceptanceAssuming the other criteria d iscussed above have been met, a cont ract w ill be formed when one party
makes an offer and the other party uncondit ionally accepts that offer.
Sometimes the offer wi ll impose restrict ions on the manner in which it may be accepted (e.g. only in
writ ing). H owever in t he absence of such restrict ions, an offer may frequently be accepted orally, in
writ ing, by e-mail or other electronic means, or may even be inferred from t he conduct of one party
e.g. by starting work.
As stated above, acceptance sent by post can sometimes be binding as soon as it is posted, even i f it is
never received. However, in practice, if the letter is lost the sender may have difficulty proving that
it was posted unless it was sent by registered post or recorded delivery.
Acceptance by all other methods of communication, such as by telephone, must actually be
communicated to th e other party before it takes effect. To date there has been no ruling on faxes or e-
mail, although it seems likely that they will be treated in the same way as telexes, and will not be
binding until received.
Given the negotiations, offers and counter-offers which often precede the award of a construction
contract , it is sometimes difficult to ascertain precisely what offer has been accepted. The following
general rules should be borne in mind:
1. If n ew terms are introduced in what purports to be an acceptance (e.g. an order) the document is
actually a counter-offer, which must in its turn be accepted before a binding contract is formed.
2. Acknowledgement of receipt of a t ender or other offer does not normally, in it self, constitute an
acceptance of that offer.
3. Silence cannot be an acceptance. Therefore if an offer is made and th e words added, w e will
proceed on the above basis unless we hear from you to t he contrary within [so many] weeks and
no reply is received, that would not in itself constitute acceptance and therefore no binding contract.
4. The acceptance may be stated to be subject to a formal contract . The precise effect of this
phrase depend s on the stat e of the negotia tion s between the two parti es. Where further
negotiations over essential terms of the contract are contemplated, there will be no bindingcontract . If all th e essential terms have been agreed and the parties intend to in corporate them
into a formal document at a later stage, there may be a bindin g contract. H owever, this will not
be the case if the parties have expressly or impliedly agreed that no contract shall come into
existence until a formal contract is executedJ. Jarvis & Sons Limited v. Galliard Homes Limited
(1999).
Counter-Offers
An acceptance which purports to q ualify an offer in any respect amounts, in law, to a counter-offer.
When faced wit h a counter-offer, th e person who made the original offer may d ecide to accept it, inwhich case a binding contract is formed on the basis of the counteroffer, or to decline it. The
counter-offer may be declined either expressly or by making yet another offer, including re-submission
of th e original. L ike any offer, in the absence of any express time limit, a counter-offer will lapse after
the passage of time.
8/10/2019 BCSA Contractual Handbook
12/245
Formation of Contracts
Chapter 1 5
Contract negotiations are frequently a series of counter-offers, but in construction contracts there
are dangers arising from the tendency to begin work before the contract negotiations are complete.
While this is an entirely pragmatic approach, it is important to ensure that beginning work is not
deemed to be acceptance by conduct of terms and conditions with which the Steelwork Contractor is
unhappy.
A typical sequence of events runs as follows:
1. A Steelwork Contractor is invited to tender for work on the basis of an unamended standard
form of sub-contract (invitation to t reat).
2. The Steelwork Contractor submits his tender on the basis of the standard form. (Offer).
3. The main contractor places an order with the Steelwork Contractor on the basis of his own terms
and condit ions wh ich appear on the reverse of th at order. (Counter-offer).
4. The Steelwork Contractor acknowledges receipt of th e order and begins work. (Acceptance of
Counter-Offer).
5. Several days after starting work the Steelwork Contractor attempts to negotiate terms of contract
with the main contractor (the Steelwork Contractor may well be bound by the terms of the
Counter-Offer).
In the above example, the Steelwork Cont ractor could have started work with out ty ing him self to the
main cont ractors terms although this does not mean th at the Steelwork Cont ractor is working under
his own t erms. It is crucial that unacceptable terms are disputed before any work is carried out, and
the Steelwork Contractor should also make clear that any off-site or on-site work does not constitute
an acceptance of the main contractors terms.
Main contractors orders frequently have an apparently innocuous tear-off acknowledgement slip
att ached at the bottom. Careful consideration should be given before such tear-off slips are signed
and returned, as they almost invariably include a statement that by signing and returning the slip
the sub-contractor is deemed to h ave accepted all of t he terms contained in the order. This would
probably result in the contract being concluded on the main contractors own terms. If Steelwork
Contractors wish to acknowledge receipt of an order, they should write a simple letter
of0acknowledgement on their own stationery, making it clear th at the terms contain ed in the order
are not accepted.
Battle of FormsThe negotiations leading up to a contract are often a series of offers and counter-offers. This is
sometimes referred to as the batt le of forms to describe each sides standard terms and cond itions
being sent backwards an d forw ards. The leading case on the batt le of forms is the Court of Appeal
decision in Butler Machine Tool Co. v Ex-Cell-O Corporation (1979).
The sellers (Butler) offered to sell to Ex-Cell-O a machine tool on th eir standard t erms which included
a variation of price clause. Ex-Cell-O ordered the machine tool on their own terms and conditions
which did not contain a variation of price clause. The buyers conditions contained a tear-off
Acknowledgement slip which contained the words, We accept your order on the terms and
conditions thereon. The sellers completed and returned the slip, accompanied by a letter statingtha t they accepted the order on the basis of their original offer.
However, the Court of Appeal held that by signing and returning the tear-off slip, the seller had
accepted the buyers terms, notwithstanding the accompanyin g letter.

Formation of Contracts
6 Chapter 1
A more recent case on the battle of forms is Sauter v Goodman (1986)which concerned a contract
for boiler replacement at Windsor Castle. The key q uestion was whether a retention of tit le clause in
Sauters own terms and condit ions had become part of the contract .
Sauter had quoted to Goodman on the basis of their own terms and conditions which included a
retention of tit le clause.
G oodman had accepted the quotat ion on terms and condit ions in accordance with th e main contract
wh ich w as G C/Works/1 Ed it ion 2. GC/Works/1 provides that every subcontract must include a term
that, all things for incorporation belonging to the subcontractor which are brought onto site in
connection wit h th e sub-contract shall vest in th e contractor, in oth er words the exact opposite of a
retention of tit le clause.
The Court h eld that Sauter had accepted G oodmans terms (which amounted to a counter-offer) by
delivering the goods, and th erefore there was no retention of tit le clause in the contract.
On the batt le of forms, the following key principles should be borne in mind by Steelwork Contractors:
1. An acknowledgement slip should not be completed and returned unless the Steelwork Contractor
agrees that the condit ions to which i t refers are acceptable in their entirety.
2. Rejection of the terms of an offer should be writt en in unequivocal terms and should be incapable
of being misconstrued.
3. If Steelwork Contractors wish to proceed with the work while continuing negotiations, they
must make it very clear prior to commencing work that by so doing they are not accepting the
employers or main contractors terms and cond itions.
Letters of intentL etters of intent are a minefield for the unsuspecting sub-contractor. Steelwork Contractors are
particularly vulnerable as they are an early trade and are therefore frequently requested to carry out
preparatory work and fabrication off-site before a formal order or cont ract is issued.
1. Definition
In law, a letter of intent is simply a statement of t he writers intentions. I t does not constitute an offer,
counter-offer or acceptance, and therefore does not create a binding contract .
L etters of intent are sometimes used as a device by t he Employer (or archi tect or consulting engineeracting on his behalf) whereby the Steelwork Cont ractor is effectively instructed to carry out preliminary
work pending the selection of a main cont ractor and the execution of a sub-contract .
In such cases although a document may be headed letter of intent , consideration of its content may
reveal th at it is actually an acceptance or counter-offer which requests the recipient to carry out all or
part of the work referred to in the letter. If the so-called letter of intent makes it clear that all t he
essentia l terms of the contract have been agreed, commencement of work following receipt of such a
letter may lead to a contract coming into being. In the event of a dispute as to whether or not a
contract had actually been concluded, the Court would take into account th e heading of the document
but it would not be decisive in determining its nature. The Court would look at the content of the
document, and , if it was in substance an acceptance or counter-offer, th ey would construe it as such.
2. Terms of Letter of Intent
When a Steelwork Contractor receives a letter of intent, his first thought should be: If I act on th is and
the job is subsequently cancelled (or given to someone else) will I get paid for the work Ive done?
8/10/2019 BCSA Contractual Handbook
14/245
Formation of Contracts
Chapter 1 7
Provided the letter clearly instructs the Steelwork Contractor to undertake the work, and the Steelwork
Contractor does not go beyond that instruction, the answer to that question is likely to be yes: the
Steelwork Contractor will be entitled to be paid for t he work he has carried out.
As to payment for work done in reliance upon a letter of intent, in t he absence of any provisions in
the letter about payment, the Court would imply an entitlement to payment of a reasonable sum
(sometimes referred to as quan tum meruit) for the work. A Steelwork Cont ractor s position w ould
be strengthened if the letter included an express undertaking to pay a reasonable price for the work
executed. I f the letter simply refers to covering the costs incurred, Steelwork Contractors should be
aware tha t wh ile a reasonable price w ill include overheads and profit, costs may not . The phrase
loss and expense has been equated by the courts wi th d amages, and would therefore be preferable
to costs as it would include overheads and profit. Obviously the best position for a Steelwork
Contractor as to payment under a letter of intent would be one where the price or the rates for his
work are clearly set out or referenced in the letter.
It is vital that the Steelwork Contractor does not carry out more work than i s authorised by th e letterof intent. I deally, the letter should identify in detail wh at th e Steelwork Contractor is required to do.
For a Steelwork Contractor this will normally comprise:
(a) ordering the material
(b) designing the connections
(c) preparing detailed drawings
(d) planning the contract both on site, and at the Steelwork Contractors works
(e) fabricating the material
If the Steelwork Contractor is required to carry out work beyond that specifically authorised, he
should obtain a further written instruction (including an undertaking to pay) from the party who
issued t he letter of intent.
3. Obligations Regarding Time
With t he popularity of fast-track construction th e question of how q uickly work must be carried
out is becoming increasingly important. I f no contract is ever agreed, it seems that there is no obligat ion
to adhere to a particular programme. This is illustrated by the case of British Steel Corporation v
Cleveland Bridge & Engineering Co Ltd (1981). Cleveland Bridge had been engaged as
sub-contractors to fabricat e an unusual steel latt ice-work frame for a bank in Saudi Arabia. C levelandBridge approached Br itish Steel with a view to employing them to cast nodes for the frame, but the
negotiations both regarding the specification an d the terms of the contract were long and complex.
In February 1979 Cleveland Bridge sent British Steel a letter of intent which stated an intention to
place an order at the price quoted by British Steel, but on Cleveland Bridges own terms, which
placed unlim ited liabilit y on the sellers for th e costs of any d elay.
British Steel made it clear they would not accept those terms. but nevertheless constructed and
supplied the nodes. The final node was not delivered until April 1980 owing to a nat ional steel strike.
British S teel sued for the value of the nodes and Cleveland Bridge counter claimed for damages for
late delivery.
The Court held that there was no contract because the parties had not agreed on important aspects
such as progress payments and liability for late delivery. B ritish S teel could not be liable for damages
for late delivery. H owever. th ey were enti tled to be paid a reasonable price for the work because it h ad
been done at C leveland B ridges request and accepted by t hem.

15/245
Formation of Contracts
8 Chapter 1
It is not always, of course, the case that a Steelwork Cont ractor wh o carried out work in ant icipation
of entering in to a contract will be able to claim a reasonable sum for that work if the contract i s not,
ultimately, entered into. In Regalian plc v. L D D C (1995) the Court rejected the contractors argument,
holding tha t the costs which it now sought to recover were the costs of putting it self in the position
to obtain and perform th e contract.
However, this does not mean that when working on a letter of intent, Steelwork Contractors can
afford to ignore the main contractors or employers requirements regarding programme, because
any terms subsequently agreed may apply retrospectively to the work executed on the basis of the
letter of int ent. For example, in the case of Trollope & Colls Ltd v The Atomic Power Construction
Company Limited (1963)sub-contractors had tendered for a power station contract. In June 1959,
the sub-contractors were asked to start work on the basis of the letter of intent w hich read as follows:
We have to inform you that it is our intention to enter into a contract with you for (the works).
As soon as matters outstanding between us are settled we will enter into a contract agreement
with you, and in the meantime please accept this letter as an instruction to proceed with thework necessary to permit you to meet t he agreed programme.
The parties agreed the terms of the contract in April 1960, but the contract was never signed.
The sub-contractors subsequently argued that no contract had been formed an d therefore they were
entitled to reasonable payment rather than the prices they had quoted. They also argued that the
terms of the contract eventually agreed applied only t o work executed after April 1960, and did not
cover the work executed on the basis of the letter of intent.
The Court held that a contract came into existence in April 1960, and the terms of that contract
applied retrospectively.
4. Authority to Write Letter of Intent
It is important that a Steelwork Contractor checks the letter of intent is written by someone with
appropriate authori ty to act. A letter from the Employer or from the main contractor should be
acceptable. Where, however, a lett er is received from another party, such as a consultant , a Steelwork
Contractor should check with the Employer or main contractor tha t they have the necessary authority.
If a St eelwork Contractor is in any d oubt about the authority of the person who has signed the letter,
he should ask for a written confirmation from the employer or the main contractor before starting
any work.
Payment for Preparatory Work where No Letter of Intent is Issued
Following th e decision of the Court in Marston Construction v Kigass (1989), it may be possible to
recover the cost of preparatory work even w here no letter of intent has been issued. Marston tendered
for a design and build contract to provide a replacement for K igass factory, which had burn t down.
The insurers did not pay enough to cover the cost of rebuilding so the contract w as never placed, but
Marston claimed a substantia l sum for the preparatory work they had carried out over and above the
preparation of th e tender itself.
K igass had not wri tten a letter of intent , nor had they given an assurance (requested by Marston) that
the preparatory costs would be met. On the other hand, Marston were not given any ind ication thatthe preparatory work would be at their risk.
The Court held that Marston were entitled to be paid a reasonable sum for the preparatory works,
because they had been done at the implied request of K igass, and K igass had obtain ed a realisable
benefit, in the form of some design work as a result.

Notwithstanding this decision, it is obviously preferable for Steelwork Contractor to obtain clear
undertakings regarding payment before executing an y preparatory work as described in L etters of
Intent above.
Incorporation of Terms by Reference
Frequently, neither the invitat ion to t ender nor the tender itself spells out all the conditions which
will apply to any resulting contract. They will simply refer to condit ions writ ten elsewhere such as
D OM/1 . The conditions referred to will be incorporated into the as if they were writt en out in full.
The Court s have held such incorporation by reference valid even where the reference was incomplete
and partially incorrect e.g. referring to the green form as the appropriate form for nominated
subcontractors (RIB A 1965 Edition) .
Where there is an indication tha t some step, such as signature of documents, is to be taken, in order
to incorporate conditions, the Courts will take this into account in deciding whether the conditions
have been incorporated especially if the condit ions conta in onerous provisions. InJonathan Wren
& Co & anr v Microdec plc(Case Number 1999 TCC 8), the Technology and Construction Court
considered the case of a software supplier whose quote stated that it was subject to their standard
condit ions. Although the quote was signed and returned on behalf on th e buyer, the suppliers
standard conditions were not given to the buyer. In addit ion, the condit ions themselves stated that
they would only become binding w hen signed by the parties. They were never signed. The Court
held that the suppliers standard conditions were not incorporated into the contract.
Tender documents frequently include a general stat ement tha t the sub-contractor shall observe and
comply with all the terms of the main contract as if the same were set out in the sub-contract. Whether
such attempts to incorporate the main contracts terms will be successful depends on the circumstancesof the individ ual case. In Dunlop & Ranken v Hendall Steel Structures (1975)it was held that the
incorporation of th e terms of the main cont ract by loose general words would not normally b ind the
sub-contractor to specific terms in th e main contract.
Conversely, in the case of Sauter v Goodmandescribed above, the Court held that relevant main
contract terms could apply between the main contractor and sub-contractor (with the necessary
changes) so that for contractor one read subcontractor, and for Authority, contractor.
Steelwork Contractors should carefully consider whether it is appropriate to incorporate all of the
main contract terms into a sub-contract , which th ey may be about to enter into. For example, if the
main cont ractor provides for the main contractor to provide insurance covering all of the main contractworks, it may not be appropriate to impose the same obligation on a sub-contractor who will be
responsible for only part of the works. The Steelwork Contractor wi ll in any event normally expect
the main contractor to provide temporary work such as access roads and hardstandings and would
therefore not wish t o accept the obligation to provide these.
Simple and Specialty Contracts
A contract under hand is one which is simply signed by the parties. It i s sometimes referred to as a
simple contract.
A contract w hich i s executed under seal (i.e. wh ere the company seals of the parties is affixed to th e
contract) or as a deed is known as a specialty contract. Unti l July 1990, the common method of
executing a specialty contract was to impress a seal on the document. As part of a package of measures
designed to lighten the administrative burden on smaller companies, the Companies Act 1989
abolished the requirement for company seals, and introduced arrangements whereby a document
8/10/2019 BCSA Contractual Handbook
17/245
Formation of Contracts
10 Chapter 1
stated to be executed as a deed, and signed by two directors or a d irector and the company secretary,
had the same effect as if it had been executed under the company seal.
The main differences between contracts executed under hand and those under seal or executed as a
deed are:
contracts under hand have a limitat ion period of six years from the date of the breach of contract
whereas those under seal or executed as a deed have a limitat ion period of twelve years.
contracts und er seal or executed as a deed do not require consideration (see Elements of a
B inding Contract above).
Interpretation of Contract
In deciding the meaning of words used in the contract, the Courts will follow their natural and
ordinary meaning. The fact that one party may not have appreciated or intended the meaning of any
particular word s or understood their implications does not normally a ffect the position.
H owever, it is important to note that the Courts when interpreting contracts, will take account of the
factual background to the contract i.e. information available to all parties at the time the contract was
made. This may well help in situat ions where there is ambiguity.
Further, where consideration of the factual background makes it clear that the words used cannot
have reflected the int ention of all part ies, the Court will construe the contract so as to give effect to
tha t intention. This occurred in another context in Mannai Investment Co. Limited v. Eagle Star
Life Insurance Co. Limited (1997) and in Investors Compensation Scheme v. West Bromich
Building Society (1997).
Rights of Third Parties under a Contract
The tradi tional position of E nglish law has been th at Third P arties (persons not parties to a contract)
are not entit led to enforce any righ ts under that contract. This is known as the doctrine of P rivity of
Contract. The doctrine has been subject to a number of limited statutory exemptions.
The position has now been considerably changed by the Contracts (Rights of Third Parties) Act
1999. When a contract either:
a. expressly provides that the Third Party may enforce a right under the contract, or
b. purports to confer a benefit on a Third Party
the Third P arty m ay enforce provisions of the contract as though he were a party to th e contract . A
Third P arty may be an in dividual person or company or a member of a defined class. No consideration
from the Third Party is required.
There is considerable uncertainty as to th e effect of the word s quoted in (b) above. It is possible that
in certain circumstances they could be interpreted as allowing, for example, the Employer, to enforce
direct the provisions of a sub-contract against the sub-contractor. For that reason, almost all of the
standard forms are being amended to make it clear that the contract does not intend to confer a
benefit on any Third P arty.The Act came into force on 11 October 1999 and applies automatically to all contracts entered into
on or after 11 May 2000. The part ies may opt into the Act before that date. The Act does not apply
to Scotland.

Summary
Interpretation of Contracts:The Courts will normally adopt th e natural and ordinary meaning of
word s used. Where th ere is ambiguity, then that m ay be resolved by reference to th e factual
background. The Courts may disregard the literal meaning of words where it is clear from the
factual background that such an interpretation would not reflect the intention of all parties.
Third Parties:Unti l recently, a Third P arty could not in m ost cases enforce right s under a contract.
This has now changed in respect of contracts concluded on or after 11 May 2000. A Third P arty will
be able to enforce provisions under a contract wh ere the contract expressly so provides or the contract
purports to confer a benefit on the Third P arty.
Elements of a binding contract:There are five elements of a binding contract: intent, capacity,
agreement, reasonable certainty of terms and consideration. Consideration is not necessary in contracts
executed under seal. There is no legal requirement for writing, but in practice it is important for
reasons of proof.
Invitation to Treat:is merely an offer to receive offers. Invitat ions to t ender, catalogues and price
lists are normally invitat ions to treat.
Offer:a document m ay be an offer even if described as a budget price if it is sufficiently detailed to
form th e basis of a bind ing contract. Offers at large may be accepted by anyone, and therefore when
tendering to the Employer for a nominated sub-contract Steelwork Cont ractors may wish to reserve
the right to withdraw if an unacceptable main contractor is appointed.
The decision to qualify a tender is a commercial one which may result in t he rejection of the tender.
Offers may be withdrawn at any time before acceptance under English law unless the tenderer has
been paid to hold th e offer open.Acceptance:an acceptance must normally be unconditional: if it in troduces new terms it is probably
a counter-offer. Acceptance can be inferred from conduct (e.g. start ing w ork). It must be communicated
to the other party, unless made by post in which case it often takes effect when posted. If a
sub-contractor does not accept all the terms in a main contractors order, he must communicate that
fact before starting work. Acknowledgement-of-order slips provided by the main contractor normally
refer back to the terms of the order and should not be signed unless the sub-contractor wishes to
accept all t he terms contained in the order.
L etter of Intent : should include an express undertaking to pay the contractor for preparatory w ork if
no contract results, and should specificallyauthorise the work required. The sub-contractor should
not go beyond the terms of the letter of intent, and should ensure it is written by someone with
appropriate authority.
Incorporation by reference: terms incorporated by reference are binding, even if the reference is
incomplete or partia lly incorrect.

Chapter 2 1
CHAPTER 2
CLASSES OF CONTRACT
Construction cont racts fall into a number of classes or types, and the class of contract determines
whether certain documents form part of the contract and, to an extent the basis of payment to the
contractor. The most widely used standard forms are discussed in more detail in Chapter 3; t his
Chapter outlines the main d istinguishing characteristics of the main classes of construction contract.
1. Lump Sum, Without Quantities
This type of contract incorporates an agreement to carry out and complete a whole project, e.g. a
bridge, for a lump sum, in return for a stated cash sum. Such a contract is normally based on drawin gs
and specifications which taken together define the work covered by the price. Quantities are not partof the description of the work and any rates incorporated in the contract are for variation purposes
only.
In a pure lump sum contract, the contract price is to be changed only where the Employers plans
are varied (e.g. by a d esign change), and t he contractor will n ot be entitled to extra payment if carrying
out the work for which he tendered turns out to be more difficult and costly than he originally
envisaged. No work d one or cost in curred which is ind ispensably necessary to carrying out th e works
may be valued as an extra. This type of contract is not therefore suitable for a job where the extent of
the work necessary is uncertain.
JCT98 Without Quantities is an example of this class of contract.
2. Lump Sum, with Quantities
In th is type of contract, the bills of quant ities are intended to be the exact measure of the work to be
carried out. If there are errors in the bills, or if the contractor fin ds any d iscrepancy between the bills
and any other contract document, any corrections are treated as variations and are valued accordingly.
The rates in t he bills will also be used, where appropriate, for the purpose of valuing any variations
which may be ordered under the contract.
The essential feature which distinguishes a lump sum contract with quantities from that without
quan tit ies is that t he quant ities in the bill form part of th e description of the works to be done, andthus the lump sum tendered for the work is only in respect of the quantities set out in the bill: the
contractor is entit led to extra payment for an y work done beyond t hat . Any provisional sum included
within t he bills is measured and valued when th e work in respect of which th e provisional sum was
included is carried out, unless it relates to work which is to be carried out by a nominated
sub-contractor, in which case the work w ill be valued und er the relevant sub-contract terms.
JCT98 With Quantit ies is an example of th is class of contract , alth ough if the bills have been prepared
in accordance with SMM7, they may include approximate quantit ies in an otherwise firm bill. When
the contractor executes work for which an approximate quantity was included in the bills, the rate
for the approximate quant ity determines the valuation of th e work, provided the approximate quantit y
was a reasonably accurate forecast of the quan tit y of work required. Some commentators feel that the
inclusion of approximate quantities undermines, to some extent, the lump sum character of this
form of contract.

21/245
Classes pf Contract
2 Chapter 2
3. Remeasurement
A remeasurement or measure and value contract is one where the contract price is recalculated on
final measurement using the rates set out in the tender. There may be a bill of approximate quant ities
against w hich t he contractor tenders. The final quantit ies are remeasured w hen th e work is completed
and the contractor is paid at the rates he tendered for t hose measured quant ities.
The contractors tender total is simply an estimate based on the proposed volume of work to be
carried out, and has no purpose other th an as a basis for selection.
On re-measurement contracts variations are normally concerned with design or quality changes
rather than q uantity changes.
JCT98 With Approximate Quant ities and t he ICE 7th Edition are re-measurement contracts.
Under JC T98 With Approximate Quanti ties, if the approximate bills are not a reasonably accurate
forecast of the work required, the work is valued at the tendered rates and prices plus a fair allow ance
for th e difference in quantit y. Work not covered by the bills is subject to a fair valuat ion , or ifappropriate, may be measured on daywork.
4. Prime Cost
Under a prime cost contract t he contractor is entitled to be paid the actual cost he incurs in carrying
out th e work plus a fixed fee for his overheads and profit. Architects Instructions will not normally
lead to any variat ion in the fee, although ad dit ional work will be paid for as part of the prime cost.
This type of contract is normally used where an early start is required. e.g. after fire damage.
The JCT Management Contract 1998 is an example of a P rime Cost Cont ract.
5. Design and Build
The classes of contract described above are based on the tradi tional division of responsibilities between
the designer and contractor: they assume that a professional practit ioner (architect and/or engineer)
appointed by the Employer will be responsible for design, and the contractor will be responsible for
materials and workmanship.
In recent years there has been a pronounced move by clients away from trad itional contract ing towards,
amongst oth er things, design and build contracts, whereby the contractor provides a total design and
construction package. The two major characteristics of design and build contracts are that they provide
for the contractors responsibility for design and th e Employer may only vary t he design of th e works
with the contractors consent.
The JCT publishes both a standard form With Contractors Design WCD98 and a Contractors
Designed Portion Supplement to JCT98 for use where the Contractor is to design only part of the
works. WCD98 is discussed in more detail in Chapter 21.
6. Management Contracting
There are many variants of management contracting but in its most popular form the Employer
appoints a professional team, normally led by an architect and a management contractor.
The management contractor manages and co-ordinat es the project but d oes not carry out any of the
work on site: this is done by works or trade contractors, each of whom has a separate contract with
the management contractor. This method of contracting is normally of very low risk for the
management contractor, as he is relieved of th e consequences of default by th e Works Contractors,
8/10/2019 BCSA Contractual Handbook
22/245
Classes of Contract
Chapter 2 3
provided he has enforced the provisions of the works contracts against them. It is therefore the
Employer wh o takes the risk of Works Contractors insolvency or failure to pay claims.
Management contractin g is generally acknowledged to be suitable only for large and complex projects,
and i s particularly appropriate where an early start and fast completion are required.
The JCT publish a Stand ard F orm of Management Contract - MC98. Comments on MC98 are made
throughout this Han dbook.
7. Construction Management
Another approach to construction projects is construction management. U nder th is system each of
the separate trades has a direct contract with the Employer and is paid by him. The work on site is
managed and co-ordinated by a project manager or construction manager .
8. Partnering
P artnering has no precise legal meaning.
There are various types of partnering but some common features of partnering arrangements include:
An intent ion for t he parties - employers, contractors and sub-contractors - to work together co-
operatively, in good faith for the benefit of t he project as a whole. This intention is sometimes
supported by a commitment to a mission statement, arrangements for early reporting of problems
and a team approach to problem-solving.
Some form of risk/reward sharing. This may, for instan ce, involve the part ies agreeing to take
responsibility for a portion of cost overruns if the project finishes late or over budget or to be
paid a bonus if th e project finishes early or under budget.
Steelwork Contractors may derive benefits from participating in partnering arrangements but the
risks involved in such arrangements should also be considered. In particular th ey should consider:
The extent t o wh ich their exposure to taking a share of cost overruns is under th eir control or
under the control of other parties.
The extent to which their entitlement to bonus is under their control or under the control of
other part ies.
Whether the roles of and resources to be provided by each of the part ies is clearly stated or, if not ,
tha t t here are fair mechanisms for agreeing t hese.
Sometimes the high-level partnering ideals are contain ed in a n on-legally bindin g document such as
a charter leaving the legally bind ing provisions to be dealt with in contracts. In some circumstances,
however, even though a partnering charter may not be legally binding, a court may still take its
provisions into account at it did in th e case of Birse Construction Ltd v St David Ltd (1999).
The Association of Consultant Architects have recently published a Standard Form of C ontract for
P roject P artn ering PP C 2000. P P C 2000 aims to address the key recommendat ions of Sir Michael
L atham in h is report Constructing the Team . P P C 2000 describes itself as a single, fully integrated
project partnering contract, designed to underpin a t eam-based approach and to promote clarity and
confidence among partn ering team members.

9. Prime Contracting
P rime contracting aims to replace the trad itiona l confrontat ional relationships with processes which
concentrate on delivering better value. P rime Contractin g often features:
L ong term relationships between the P rime Contractor an d suppliers - not just for one project. Collaborative working.
Focus on through-life costs of a project rather than solely on capital cost.
A continuous improvement regime.
Acceptance by the Prime Contractor of responsibility for almost aspects of the project from

CHAPTER 3
STANDARD FORMS OF CONTRACT
There are various standard or model forms of contract published for use in connection with
construction projects. In this H andbook we will concentrate on the forms most likely to be
encountered by Steelwork Contractors, namely, those published by the Joint Contracts Tribunal
(JCT) and by the Institution of Civil Engineers (ICE) and the associated sub-contract forms
published by the Construction Confederation and by th e Civil Engineering Contractors Association.
The ICE have also published the Engineering and Construction Contract - a brief comment on
this form is included at t he end of this Chapter.
The JCT Forms of Main Contract and Associated Sub-ContractsThe JCT publishes a wide variety of forms of contract. Many of these forms were until recently
subject to numerous and lengthy amendments which made them cumbersome to work with.
Fortunately, in 1998 most of the relevant amendments were incorporated into new editions of the
JCT forms with the exception of th e Terrorism Cover provisions which are still separate. In this
H andbook, we will concentrate on the 1998 editions of the JCT forms. For those readers who w ish to
know more about the previous editions and the various amendments, please see Appendix A.
The forms most likely to be relevant to St eelwork Contractors are:
Standard Form of B uilding Contract - JCT98
JCT98 is the main JCT document for use where the Employer h as engaged professional consultan ts
to design the works, and requires a contractor to carry out those works by supplying the necessary
workmanship and materials. There is no upper limit on the size of project for w hich t he form can be
used, but it would be somewhat complex for reasonably simple contracts of relatively low value and
short duration.
Six versions of J CT98 have been published:
Private With Quantities
Private Without Quantities
Private With Approximate Quantities
Local Authorities With Quantities
Local Authorities Without Quantities
L ocal Authori ties With Approximate Quant ities
Nominated Sub-Contracts for use with JCT98
Various documents are issued by the JCT relat ing to nominated sub-contractors. These are referred
to in clause 35.4 of JCT98 and are as follows: NSC/T
The Stand ard F orm of Nomin ated Sub-Contract Tender. It comprises 3 parts: P art 1: The Employers Invita tion to Tender to a Sub-Contractor P art 2: Tender by a Sub-Contractor

Domestic Sub-Contracts for use with JCT98In addit ion to nominated sub-contractors, JCT 98 also provides for the appointment of domestic (i.e.
non-nominated) sub-contractors. Domestic sub-contractors are selected by the main contractor to
carry out work which has been priced by the main contractor.
JCT98 does not specify an y man datory form of domestic sub-contract .
Most large main cont ractors have their own forms of domestic sub-contract, but there is a standard
form, DOM/1, which is published by the Construction Confederation. DOM/1 is published
in two parts: the Articles of Agreement and th e Sub-Contract Condit ions.
Intermediate Form IFC98 Main Contract
This form is intended for use on projects where JCT98 is considered to be too heavy-weight.
Notes on the back of IF C98 state that i t is suitable for use where:
1. the works are of simple content (i.e. involving the normally recognised trades and skills of the
industry);
2. there is no specialist complex work:
3. the work is adequately specified and billed pre-tenderThe main provisions of IF C98 and the way s in wh ich it allocates risk are generally similar to JCT 98.
However, the contract is much shorter than JCT 98,and some of the procedural aspects of that
document have been omit ted.
The main differences between JCT98 and IFC98 are:
1. JCT98provides for th e nomination of sub-contractors, whereas IF C98 provides only for namin g,
which is an upgraded form of domestic sub-contracting whereby the architect selects the
sub-contractor, but once appointed h e is treated as a domestic sub-contractor.
2. IF C98 does not allow for conventional fluctuations. Contracts are let either on a fixed price or
formula basis.
There is an embargo on oral instructions under I FC 98.

Standard Forms of Contract
Chapter 3 3
Sub-contracts for use with IFC98
Clause 3 of IF C98 permits the appointment of tw o types of subcontractor: named and domestic.
Named Sub-Contracts for use with IFC98Where a named sub-contractor is to be appointed, the Employer (or th e architect/engineer on his
behalf) selects the tender list, invites tenders, selects the sub-contractor and instructs the main
contractor to enter into a sub-contract w ith that sub-contractor. The use of both a stan dard form of
tender (NAM/T) and a standard sub-cont ract (NAM/SC) is man dat ory. To th is extent, naming is very
similar to nominat ion. H owever, named sub-contract work will be priced by the main contractor,
and will n ot be the subject of a prime cost sum.
Once the sub-contractor has been selected, he is t reated like any other domestic subcontractor, albeit
he has the protection of a standard and mandatory sub-contract form. The named subcontractor
does not receive copies of architects certificates of payment, and it is the main contractor who issuesinstructions to him and awards extensions of time. For these reasons, naming under IFC98 should
be regarded as upgraded domestic sub-contracting rather than down-graded nomin ation.
In add it ion to the stand ard tender, NAM/T, and the standard sub-contract, NAM/SC, there is an
Employer/Subcontr actor agreement, E SA/1, which deals with design carried out by n amed
subcontractors.
Domestic Sub-Contracts for use with IFC98
A standard form of d omestic sub-contract for use with the Intermediate Form called IN/SC has beenproduced. This document is completely optional: the main contractor is free to use his own terms
and condit ions if the sub-contractor agrees. IN/SC is produced in t wo parts: the recitals and articles
of agreement. Which incorporate by reference the separately issued cond itions of contract.
In view of the named sub-contractors essentially d omestic status once he has been appointed, the
terms of I N/SC are very similar to th e terms of NAM/SC.
JCT With Contractors Design Main Contract WCD98
The JCT With Contractors D esign Form WCD 98 is for use where the contractor is designing
the works. This form has become increasingly importan t, part ly because of the trend t owards design
and build cont racts and also because the form is used by some major private sector employers where
the contractor is required to have only a partial design input.
WCD 98 requires the Employer to state his requirements, which may be little more than a d escription
of the accommodat ion required, or an yth ing up to a full scheme design prepared for t he Employer by
his own consultants or other professional advisers.
In response, the contractor submits his proposals for th e design of the works, a lump sum price
and a contract sum analysis which will be the basis of valuing changes (variations) in the
Employers requirements. A more detailed commentary on WCD 98 is given in Chapter 21 - JCT

Sub-contracts for use with WCD98
The JCT itself has not published any standard forms of sub-contract for use with WCD 98, and as all
sub-contractors under WCD98 are domestic, no standard sub-contract is stipulated. However, the
Construct ion Confederat ion have issued a standard form, D OM/2. D OM/2 comprises Articles of
agreement, and a set of conditions.
JCT Management Contract 1998- MC98 Main Form
MC98 comprises Articles of Agreement and Conditions.
MC98 is deliberately low risk for the Management Contractor. Essentially, the Management Contractor
manages the construction process while th e work on site is actually carried out by Works Contractors.
The JCT advises that suitable conditions for use of the Management Contract would be where:
(i) the Employer wishes the design to be carried out by an independent architect and design team
(ii) there is a need for early completion
(iii) the project is fairly large
(iv) the project requirements are complex
(v) the Employer while requiring early completion want s the maximum possible competition in
respect of the price for th e building works.
Under MC98, th e design of the project is to be carried out by a P rofessional Team comprising an
architect or contract administrator, quantity surveyor and any other professional advisers as are
necessary, for example, consulting or structural engineers.
Works Contractors may also carry out some design w ork, which is catered for both by t he separate
Works Contractor/Employer agreement and a provision in the Works Contract w hich makes the
Works Contractor liable to the Management Contractor for the failure to exercise reasonable skill
and care in any d esign he carries out.
The Management form is not a lump sum contract. The quanti ty surveyor prepares a Contract Cost
Plan which is an indication of the price the Employer will pay for his project (exclusive of the
Management Contractors fee). The Management Cont ractor is entit led to be paid the actual cost of
building the project (i.e. the prime cost). In addit ion to the prime cost, the employer also pays th e
Management Contractors fee for his management services, wh ichcan be either a lump sum or may
be calculated as a percentage of the contract cost plan tota l.The project period i s divided in to t wo phases: a pre-construction period and a construction period.
D uring the pre-construction period the Management C ontractor will prepare a detailed construction
programme, assist in appointing Works Contractors and advise on th e practical aspects of design.
Before the end of the pre-construction period the Management Cont ractor an d the P rofessional Team
must have agreed upon the Contract Cost P lan, and the content of the all important thi rd schedule
of MC98 which is a list of the services to be provided by t he Management Con tractor.
When the Architect decides that it is practicable to commence construction of the project, the
Employer must decide whether he wishes the Management Contractor to proceed. In other words,
there is a break clause between th e pre-construction and construction periods, which gives theEmployer an opportunity t o decide whether he wishes the same Management Contractor to contin ue
into the construction phase. If he does not, then the Management Contractor is paid a separate
pre-construction period man agement fee which is identified in his tender.

Standard Forms of Contract
Chapter 3 5
During the construction period the Management Contractor has possession of the site. He is not
contractually responsible for the prime cost of the project i f it exceeds the contract cost plan total,
but he is contractually responsible for securing the completion of th e project on or before the da te of
completion. His main obligation during the construction period is to set out, manage, organise,
supervise and secure the carrying out and completion of the project t hrough the Works Contractors.
The provisions of MC98 in terms of risk are somewhat complex. The Management Contractor is
fully liable to the Employer for breach of obligations regarding t ime, workmanship and mat erials by
the Works Cont ractors. He must enforce th e terms of th e Works Cont racts, if necessary to the extent
of taking any disputes to adjudication, litigat ion or arbitrat ion. However, the Management Contractor
is entit led to be paid by the Employer the costs of such litigation or arbit ration, provided it has been
undertaken after consultation with the Employer and the architect. Any shortfall which cannot be
recovered from the Works Contractor (for reasons of in solvency or oth erwise) is borne by the Employer
and not the Management Contractor. Similarly, the Employer may recover liquidated damages from
the Management Con tractor only to the extent that the Management Contractor recovers them from
the Works Contractors.
The only exception to these relief provisions is where the Management Cont ractor has incurred
costs due to his own negligence in carrying out h is duties which are listed in the th ird schedule.

rates may be altered.
Sub-Contracts for use with ICE 7th
The ICE 7th prohibits sub-contracting of the whole of the works without the prior consent of the
Employer. Sub-contracting of part of the works is permit ted but the extent of the works to be sub-
contracted and th e name and ad dress of the sub-contractor must be notified to the Engineer prior to
the sub-contractors entry onto the site or, where the sub-contractor is carrying out design, on
appointment.
The ICE 7th provides for the appointm ent of nomin ated sub-contractors, but does not make the use
of a standard form of sub-contract man datory.

Standard Forms of Contract
Chapter 3 7
Some of the key feature of the Engineering and Construction Contract are:
The wording of the Engineering and C onstruction Cont ract is much simpler than tha t found in
the other standard forms especially the JCT forms w ith none of the extensive cross referencing
of provisions which is a feature of the JCT forms.
The Contract includes a mission statement that the parties will act in a spirit of mutual t rust
and co-operation.
It provides for both part ies to give to the other early warn ing of any matt er which could increase
the tot al of the prices or delay completion or impair the performance of th e works in use.
The Contractors liability for defects in the works due to his design that are not listed in the
defects certifi cate are limited to the amount stated in the contract da ta (in addit ion to any stat ed
damages for delay or low performance). If Option M is incorporated into the contract, the
Contractor w ill not be liable for defects in the Works caused by his design provided he can prove
th at he used reasonable skill and care to ensure that h is design complied with th e Works
Information.

CHAPTER 4
TENDERING PROCEDURES
As explained in Chapter 1, a tender is a form of offer and will form th e basis of a bindin g contract if
it is unconditionally accepted. This Chapter deals with general tendering matters, particularly the
Code of P ractice for the Selection of Subcont ractors . The Code was published as part of a series of
Codes and Guidance Documents by the Construction Industry Board in April 1997. This Chapter
also describes the tendering procedures under the standard forms of subcontract, and comments
upon the standard tender documents.
Qualifications to t enders and withdrawal of tenders are dealt w ith in Chapter 1-Format ion of Contracts.
The CIB Code of Practice for the Selection of SubcontractorsThe Code states that it is aimed at improving the quality, effectiveness and efficiency of the
construction industry.

Criteria for q ualification to in clude [2.3]: work quality past performance overall competence health and safety record financial stability insurance cover size and resources
technical and organisational ability ability to innovate
Main contractors to regularly review their list and not ify any addi tions or removals.[2.5] It should be noted that whilst the Code is stated to apply to sub-contracts/sub-sub-
contract s of more than 10,000 (excluding VAT), there is no reason why t he principles
should not be applicable to contracts of any size.
SELECTION FOR A SPECIF IC P ROJECT
Main contractors to draw up preliminary list (e.g. from an approved list of qualified
subcont ractors). [2.6]
Tenderers on preliminary list to be asked if they are willing to tender. [2.8]

Any briefing sessions must have standard agenda to ensure consistent t reatment.
Point s to note: The informat ion to potential t enderers should include:
job and location nature, scope and approximate value of the sub-contract works including reference
to the extent of any design work required the likely dates and duration of both the tendering process and the sub-contract
works the number of tenderers being invited to submit a formal t ender whether the main contractor is already being appointed or is also tendering the main contract t ender date the approximate value and period of the main contract , if known whether, and how, any costs of tendering, may be shared whether the tender will be based on bills of quantities or other pricing documents
or on specification and drawings the selection procedure and selection criteria the main and sub-contract conditions the names of the client and t he relevant consultan ts
COMPILING TENDER LISTS

of w illingn ess to tender. [2.13]
Potential tenderers to notify unwillingness to tender before issue of full tender enquiry
documents. [2.13]
Maximum number of invita tions t o tender not t o exceed 6 in respect of construct/install
only. For design only, maximum is 4. For design and construct maximum is 3. [2.15]
If m inimum n umber of tenders is received contractor should not seek more. D esign only =
3. Construct only = 4. Design and construct = 2. [2.15]
Potential tenderers to reconfirm willingness to tender if tender documents not received

post-tender negotiations break down.[4.9]
In general, tender prices can only be changed in exceptional circumstances e.g. where the
programme or scope of the works in respect of specification, quantities, programme havechanged or where more information has become available.[4.11]
Where a preferred sub-contractors tender is used in a main (or principal sub-contract) tender
submission, the sub-contractor should be notified.[4.12]
The identity of t he sub-contractor whose price has been incorporated in t he main cont ract
tender should be notified to the client unless the client has indicated that this is not
