The Contractor is to check and verify all building and site dimensions,levels and sewer invert levels at connection points before work starts.The Contractor is to comply in all respects with current BuildingLegislation, British Standard Specifications, Building Regulations,Construction (Design & Management) Regulations, Party W

all Act, etc.whether or not specifically stated on this drawing. This drawing mustbe read with and checked against any structural, geotechnical or otherspecialist documentation provided.

This drawing is not intended to show details of foundations, groundconditions or ground contaminants. Each area of ground relied upon tosupport any structure depicted (including drainage) must be investigatedby the Contractor. A suitable method of foundation should be providedallowing for existing ground conditions. Any suspect or fluid ground,contaminates on or within the ground, should be further investigatedby a suitable expert. Any earthwork constructions shown indicate typicalslopes for guidance only & should be further investigated by a suitableexpert.

Where existing trees are to be retained they should be subject to a full

Arboricultural inspection for safety. All trees are to be planted so as toensure they are a minimum of 5 metres from buildings and 3 metres fromdrainage and services. A suitable method of foundation is to be providedto accommodate the proposed tree planting.

Sketch proposals are for illustrative purposes only & as such aresubject to detailed site investigation including groundconditions/contaminants, drainage, design & planning/densitynegotiations. Sketch proposals may be based upon enlargements ofOS sheets & visual estimations of existing site features, accuracywill therefore need to be verified by survey. Sketch proposals have notbeen considered in respect of CDM Regulations.

BUILDING REGULATIONS NOTES

CDM REGULATIONS 2015

The client must abide by the Construction Design and Management Regulations

2015. The client must appoint a contractor, if more than one contractor is to beinvolved, the client will need to appoint (in writing) a principal designer (to plan,manage and coordinate the planning and design work) and a principal contractor (toplan, manage and coordinate the construction and ensure there are arrangementsin place for managing and organising the project).

Domestic clientsThe domestic client is to appoint a principal designer and a principal contractorwhen there is more than one contractor, if not your duties will automaticallytransferred to the contractor or principal contractor.

The designer can take on the duties, provided there is a written agreementbetween you and the designer to do so.

The Health and Safety Executive is to be notified as soon as possible beforeconstruction work starts if the works:

(a) Last longer than 30 working days and has more than 20 workers workingsimultaneously at any point in the project.Or:(b) Exceeds 500 person days.

THERMAL BRIDGING

Care shall be taken to limit the occurrence of thermal bridging in the insulationlayers caused by gaps within the thermal element, (i.e. around windows and dooropenings). Reasonable provision shall also be made to ensure the extension isconstructed to minimise unwanted air leakage through the new building fabric.

MATERIALS AND W

ORKMANSHIP

All works are to be carried out in a workmanlike manner. All materials andworkmanship must comply with Regulation 7 of the Building Regulations, all relevantBritish Standards, European Standards, Agreement Certificates, ProductCertification of Schemes (Kite M

arks) etc. Products conforming to a Europeantechnical standard or harmonised European product should have a CE marking.

SITE PREPARATIONGround to be prepared for new works by removing all unsuitable material,vegetable matter and tree or shrub roots to a suitable depth to prevent futuregrowth. Seal up, cap off, disconnect and remove existing redundant services asnecessary. Reasonable precautions must also be taken to avoid danger to healthand safety caused by contaminants and ground gases e.g. landfill gases, radon,vapours etc. on or in the ground covered, or to be covered by the building.

EXISTING STRUCTUREExisting structure including foundations, beams, walls and lintels carrying new andaltered loads are to be exposed and checked for adequacy prior tocommencement of work and as required by the Building Control Officer.

LINTELS- For uniformly distributed loads and standard 2 storey domestic loadings onlyLintel widths are to be equal to wall thickness. All lintels over 750mm sized internaldoor openings to be 65mm deep pre-stressed concrete plank lintels. 150mmdeep lintels are to be used for 900mm sized internal door openings. Lintels tohave a minimum bearing of 150mm on each end. Any existing lintels carryingadditional loads are to be exposed for inspection at commencement of work onsite. All pre-stressed concrete lintels to be designed and manufactured inaccordance with BS 8110, with a concrete strength of 50 or 40 N/mm² andincorporating steel strands to BS 5896 to support loadings assessed to BS5977 Part 1.For other structural openings provide proprietary insulated steel lintels suitable forspans and loadings in compliance with Approved Document A and lintelmanufactures standard tables. Stop ends, DPC trays and weep holes to beprovided above all externally located lintels.

All foundations to be a minimum of 1000mm belowground level, exact depth to be agreed on site with Building Control Officer to suitsite conditions. All constructed in accordance with 2004 Building RegulationsA1/2 and BS 8004:1986 Code of Practice for Foundations. Ensure foundationsare constructed below invert level of any adjacent drains. Base of foundationssupporting internal walls to be min 600mm below ground level. Sulphate resistantcement to be used if required. Please note that should any adverse soil conditionsbe found or any major tree roots in excavations, the Building Control Officer is tobe contacted and the advice of a structural engineer should be sought.

WALLS BELOW

GROUNDAll new walls to have Class A blockwork below ground level or alternatively semiengineering brickwork in 1:4 masonry cement or equal approved specification.Cavities below ground level to be filled with lean mix concrete min 225mm belowdamp proof course.
