    Methods of Construction

    1. Preparatory Works for RC Columns, Beams, and Slabs

    a. Alignment and Grading

    Line and Grade Engineer should see to it that alignment and grading of structuralelements are observed with regards to the plans provided prior to rebar, form, and

    concrete works.

    Inspection of Alignment and Grading

    b. Rebar Testing

    Rebar Testing is done in order to check whether the rebar to be used in

    construction are satisfying the specifications indicate especially with regards to yield

    strength.

    Rebar Specifications

    GOLDEN FORTUNE TECHNO-BUILT INC. 7

    c. Rebar Fabrication

    In ordering rebars, available sizes are 6m to 15m with an increment of 1.5 meters.

    In some cases, desired sizes are unavailable or out of stock and some alterations on

    design of rebar placement should be done. These changes may be present on the

    cutting lists provided by the quantity surveyor. Details of splicing zone, development

    length of hooks, etc. are the most critical phases for fabrication of rebars.

    Beam Stirrups and Column Ties

    d. Scaffoldings

    In this site, they are observing the concept of 2 strong floors prior to monolithic

    concrete pouring of slab and beams at the upper floor. This means that scaffoldings

    are provided on 2 floors below the floor in which concrete pouring is to be done.

    GFTBI (Golden Fortune Techno-build Incorporation) is observing this concept in

    order to maintain safety.

    Scaffoldings are designed to be able to carry the weight poured concrete to

    prevent any collapse, damage, or harm especially from the laborers.

    Strong Floor with Scaffoldings

    2. Installation of Rebars in Columns

    a. Rebar Installation

    After line and grade checking and rebar fabrication, these may now be installed

    by the steel men. Safety measures should always be observed upon installation of bars

    especially in columns because these are done vertically at a significant height. Safetyequipments like hat, harness, etc. should be used when doing this job. Incompliance

    to these safety measures may result to injury or casualties.

    b. Formworks System and Installation

    The contractor of this project Orchard Residences uses the EFCO System

    (Economy Forms Corporation). This system uses steel panels (for columns) that are

    laterally connected using ties in order to prevent movement of forms to observe

    proper alignment, plumbness, and elevation and as well as prevention of bursting of

    concrete.

    b. Scaffoldings Installation

    Scaffoldings are designed and placed properly prior to rebar installation in order

    to prevent hazards or injuries. These scaffoldings are used to avoid movements of

    forms that may alter the alignment upon rebar and concrete works to be done.

    Scaffoldings for Beams/Girders and Slabs

    c. Beam Rebars and Stirrups Installation

    After alignment and grading check, beam rebars may now be placed. Steel men

    must observe proper placement of these rebars and should maintain safety at all times.

    Proper PPE should be used in order to avoid accidents or injuries upon rebar

    placement.

    Stirrups must be installed properly by steel men to avoid discrepancies on the

    values of spacing with regards to the key plan provided.Stirrups should be tied well

    to avoid movement of shear reinforcements upon concrete pouring.

    e. Rebar Installation for Slabs

    After installation of bars at beams and as well as MEPF installation, rebars for

    slabs may now be installed by the steel men.Proper spacing should be observed to

    avoid discrepancies with regards to the key plan.Rebars should be properly tied and

    well placed to avoid movements upon concrete pouring.

    Rebar Installation in Slabs

    4. Preparatory Works for Concrete Pouring

    a. Pumpcrete

    Pumpcrete is a construction equipment consist of a machine and series of pipes

    that is used to transport concrete from lower elevation to higher elevation. Before

    using the Pumpcrete bags of cement are fed into the machine. These acts as a grout

    that helps smoothen the surface of the pipe so that concrete can slide through easier.

    This construction equipment should be prepared and placed in the proper area in

    order to avoid obstructions.

    Pumpcrete pipe placing prior to pouring of concrete

    b. Placing Boom

    A construction equipment incorporated with the pipes of the Pumpcrete. It is used

    to maneuver the pipe around the area where the pouring is needed. This equipment

    should also be properly placed prior to rebar placement in order to avoid obstructions.

    GOLDEN FORTUNE TECHNO-BUILT INC. 15

    c. Inspection

    Inspection prior and after a certain work at site is done by QA (Quality

    Assurance)/QC (Quality Control) Engineer. QA Engineer should inspect the rebar

    count and spacing after the placement of column, beam, and slab rebars.

    Inspection of Rebar Count, Spacing, and Placement

    After rebar placement and formwork installation, QA/QC Engineer should inspect

    the plumbness, squareness, alignment, and grading of formworks accompanied by an

    Architect prior to concrete pouring.

    5. Concrete Pouring

    After finishing all preparatory works, concrete pouring may now be done. In

    concrete pouring, placing boom connected to the stationary pumpcrete is used.

    Certain quantity of concrete cylinders depending on the volume of concrete to be

    poured must be tested in order to check the strength of delivered concrete. Concrete

    on Columns should have a least strength of 8500psi as prescribed by the designer of

    this project and Concrete on Beams and Slabs have a least strength of 6000 psi.

    TESTING OF MATERIALS

    Quality Assurance (QA) testing is provided for the verification of the adequacy and

    effectiveness of GFTBI QC testing. QA testing is performed by Quality Control (QC) officer

    and is independent of and in addition to QC testing performed by GFTBI. QA testing may be

    performed on pre-established schedule or as directed by CM.

    QA testing will be performed by or under supervision of the QC staff to validate the

    GFTBI QC sampling and testing. Such testing maybe performed by third party testing

    service. In lieu of performing independent test the CM QC may choose to witness QC testing

    or conduct test on split samples from QC testing. When QA and QC test results do not

    compare or have wide variances, additional testing maybe needed to validate the results.

    Additional test to be performed by field inspector or the third party testing services will be at

    the direction of CM QC officer.

    The need for QA testing shall be based on the following considerations.

    Importance of the items as to its reliability, etc.

    Need to perform quality checks for fabrication sequences not available for inspection

    at completion, and

    Deficiencies are discovered.

    GFTBI will provide a one day advance notice of impending hold points. Field

    inspector conducting the quality test and inspections shall complete the daily construction

    report. The daily construction report will be distributed to the Owner, CM site manager,

    GFTBI PM, and or QC officer. CM will review QA test and maintain file for all field QA

    documentation.

    Concrete

    In the sampling and testing of concrete, before the actual pouring the concrete is subjected to

    slump test with which 75mm of drop is the acceptable value.

    In addition to that, minimum of six (6) cylindrical samples were taken for compressive

    strength test. The size of sample varies depending on the design mix of the concrete and it

    measure 4 by 8 or 6 by 12. The six cylindrical samples are tested during its 7th

    , 14th

    and

    28th

    days of the concrete. Proper curing of the samples is applied to avoid any error.

    They put plastic bag on the sample concrete for the

    moist to circulate. Before testing of concrete they

    drain it minimum of 3 hours.

    GOLDEN FORTUNE TECHNO-BUILT INC. 35

    Documentation and Record Keepingis one of the most important parts of construction.

    It is a compilation of important information and data involved in the process of construction. It

    includes progress reports, file documents, and details about the project. Without these reports, itwould be difficult for the company to stand firm whenever there will be issues regarding the

    construction. These might serve as proofs that will support situations. And everything must be

    recorded for the data collection.

    Once the project has started Progress Reports and Record Keeping should, at the sametime start. Progress reports must be in a form of daily reports, weekly reports and monthly

    reports. This is to further monitor the development and/or changes in the project. These reports

    can be in a form of checklist, narrative observation, or a detailed report with photos and billings.

    DAILY REPORTS

    Daily Reportsincludes the work done within the day, extra work done, manpower count,

    equipment, kind, number and status. This also includes the weather condition within the dayfrom am to pm. This is to determine how the work will be affected by the uncontrolled situations

    just like the change in weather. The report is called Daily Project Log which is done daily. It is

    prepared by the Planning Engineer and must be submitted to the Project-in-Charge.

    Log Booksis a record book that is done by the site supervisor. All the observations and

    activities done during the day is recorded and kept on the office. This may serve as a reference

    during a meeting. It is very important to keep hold of records of whatever happened for a specificso that if there will be problems encountered, it would be easier to trace on what part exactly it

    has started. It is necessary to have this daily logbook as part of an effective project management.

    Additional forms such as Accident Reports and numerous checklists help make sure that you're

    covered.

    It is very important for the contract to be updated of the weather forecast. One of the

    uncontrolled variables in construction is the change in weather; it highly affects the work, cost,

    time and progress. This is done to systematize the sequence of work and further adjustments onthe construction. This is important because, a work cannot be pursued if there is a coming storm

    or typhoon, not only for the contractor but also for the safety of the workers.

    highly on the cost of the project. This three months look ahead schedule enables to manage the

    work accordingly to the deadline.

    This includes schedules, graphs, progress photos, etc. to further support the

    accomplishment done in the project. Progress photos must be properly labeled to make it easier

    for the project manager and/or owner to understand.

    COST DOCUMENTATION

    Cost Documentation is basically the cost estimation of the whole project, starting from

    the manpower utilizations, equipment utilizations and material cost. Every cost related matters

    on the site must be kept recorded and documented. It is very important for the owner to be

    updated and properly informed on this matter.

    Manpower and Equipment Utilization Reports

    Manpower Utilization reports is monitored daily. The site supervisor summarizes thedesignation, number of employees per designation and total number of working hours allotted on

    a particular day. The total number of hours of the employees is compared to the previous total

    hours and then the total running time is computed. It is important to be guided with this becausemanpower cost depends on each day of work. It must be balanced and any adjustment of labor

    must be planned. One should not increase or decrease number of workers without thinking of it

    carefully. Sequence of work and time schedule are to be considered.

    Equipment Utilization report is also monitored daily. The site supervisor summarizes the

    kind of equipment, number of available equipments and its status. The status of the equipmentcan be classified as idle, breakdown and operational. Monitoring this helps in controlling the

    equipments needed in the construction. Equipments must consider the work volume, which is

    done by the working engineer (project manager, project-in-charge, project engineer) on the site,

    before any changes to be made.

    Material Cost Control Reports

    This is done to determine the total percentage of delivered materials that has been used inthe site. It includes the quantity, unit and state of the materials on the site. It is important to keepa record of the materials delivered because it is to manage properly whether there are enough

    stock of materials or there is a need for a new set of delivery.

    Project Management Software used by the Planning Department:

    Microsoft Project is a project management software program, developed and sold by Microsoft,which is designed to assist a project manager in developing a plan, assigning resources to tasks,

    tracking progress, managing the budget, and analyzing workloads. The application creates

    critical path schedules, and critical chain and event chain methodology third-party add-ons alsoare available.

    A CPM schedule created using Microsoft Project

    Microsoft Excel is a spreadsheet application developed by Microsoft. It features calculation,graphing tools, pivot tables and macro programming language. It is used in monitoring the cost

    and cash flow of the project. The S-curve and cash flow can be easily graphed based on what isindicated in the scheduling made from Microsoft Project.

    The S-curve using Microsoft Excel

    Project Schedule:

    S-curveis defined a display of cumulative costs, labor hours or other quantities plotted against

    time. The beginning represents a slow, deliberate but accelerating start, while the end

    represents a deceleration as the work runs out.

    Prior to project commencement, a schedule is prepared outlining the proposed allocation of

    resources and the timing of tasks necessary to complete the project within a set time frame andbudget. This schedule is referred to as the Baseline Schedule. From this schedule, a Baseline S-

    curve is generated. This S-curve reflects the planned progress of the project. If the project

    requirements change prior to commencement like change of scope and delayed start, the Baseline

    Schedule may require revision to reflect the changed requirements.

    This is the latest S-curve showing

    slippage of the plan and actual

    accomplishment. The red line

    shows the actual progress while the

    blue line shows the estimated cost

    and time plan.

    Cost Report/ Cash Flow

    The cash flow forecast how much they will amount to during the life of project. Predicting cash

    flow is important in order to ensure that an appropriate level of funding is in place and that

    suitable draw-down facilities are available. Until the main contractor has been appointed, cashflow projections are likely to be based only on agreed fee payment schedules for consultants and

    a simple division of the construction cost over the likely construction period perhaps an

    allocation of construction cost over an s-curve distribution.

    Delays Encountered:

    Time delays happen because the actual condition in the site is not the same as planned like

    weather condition and other factors that affect the work progress. Another reason is if there will

    be revisions to the original plan. These delays are reflected through slippage in the S-Curve.

    The owner, Orchard Residences, decided to add a basement which is not included in the original

    plan that resulted to a delay of schedule compared to the S-Curve prepared from the contract.

    Because of this, there will be a revised or catch-up schedule that is currently on process (46-

    month construction). As of now, the Golden Fortune Techno-Built Inc. is still adopting the

    original schedule and S-Curve (38-month construction).

    Here are some solutions used by the Planning Department:

    Manpower

    It means that in order to meet the time scheduled, the contractor can add more workers to

    do the project. However, this solution needs more budget to implement it.

    System

    In this solution, the Golden Fortune Techno-Built Inc. changed their formwork system

    from EFCO System to Aluma System. In the West Building, they used EFCO System but

    they notice that their work is delay so they change the formwork system of the East

    Building to Aluma System to catch-up the schedule. Aluma System has bigger plate,

    meaning it can save time in forming it and will accelerate the progress of their work. But

    this solution may need extra cost since they started their work using EFCO System.

    Working Times (overtime)

    It means that the workers and engineers should extend their working hour than the normal

    working hour or what we call overtime. In this solution, the progress of their work will

    accelerate because of continuously working until they reach the target schedule. Like the

    other two solutions, this solution will also need more budget.

    Cost Variances:

    A variance is the difference between a budgeted/ planned cost and the actual amount. The

    concept of variance is intrinsically connected with planned and actual results and effects of the

    difference between those two on the performance of the general contractor. It is based on the unit

    of quantities and the S-Curve. As of now, there is 0.00% variance in the project.

    There are cases that negative variance occurs. It is when the actual amount is greater than the

    budgeted/ planned amount. In order to avoid negative variance, the contactor should know how

    to balance and control the cost of the project.

    Here are some of the ways how contractor adjust the operation to address cost variance:

    Proper measurement and monitoring of the materials

    It is important in construction because every materials delivered to the site should be used

    in order to avoid wasting them. Proper supervision of the cost of materials should be

    implemented.

    Proper measurement and monitoring of accomplishments

    Work accomplishment should be documented weekly to monitor the quantity of materials

    needed. If accomplishments are not documented, there is a tendency of ordering excess

    materials like rebars that could cause cost variance.

    Progress Payment Procedures (Progress Billing with Supporting Documents)

    The contractor is paid progressively throughout the project and is required to submit progressclaims to the architect on a regular basis. The architect assesses each claim on the basis of work

    undertaken, the labor and materials used, and any other construction costs in accordance with the

    construction contract, and then issues a progress certificate which stated the amount calculatedby the architect to be due to the contractor at the time of issue.

    Under most building contracts, the architects responsibility to prepare and issue progress

    certificates is as an independent professional assessor upon whose assessment and valuation bothyou and the contractor have agreed to abide. It is one of the few instances under the contract that

    the architect does not act as your agent and you must not do anything which prevents your

    architect from carrying out that role of assessor and certifier independently of you.

    Process and obligations for progress payments:

    The contractor presents a progress claim to the architect

    The architect assesses the claim, determines the monetary amount which the contractor is entitledto under the contract and issues a progress certificate to the contractor

    The contractor presents the progress certificate and a tax invoice to you for payment

    The building contract usually states a limited time within which you must make the payment

    Time Extension

    Extension of time is based on the ability to demonstrate that delays have occurred in

    theconstruction schedule affecting project completion date. Time extension requests arenormally specified in contracts provision and requesting time extensions should be madefollowing all steps and documentation under the contract guideline. When requesting a time

    extension the Contractor should notify the Project Manager, when any issue might affect the

    project schedule.A formal letter must be addressed to the Contract Administrator requesting the

    time extension and the reasons why those days should be added to theconstruction schedule.TheContract Administrator should then, remit the letter to the Project Manager for evaluation and

    approval or rejection. If the time extension is granted, then the Project Manager must answer by

    written and a change order will be issued. Some contracts specify that time extension requests

    should be done within a specific time frame, if not; the time extension claim will also berejected. Time extension document should have this following:

    Indicate specific issue causing delays

    List of activities from project schedule being affected by the aforementioned issue

    Exact amount of time being requested specifying working days or calendar days

    Sketches, photographs, or pictures

    Recommendations being given to Contract Administrator

    Indicate the actions the contractor has taken to avoid or minimize other delays

    Alternative solutions presented to Contract Administrator

    Time extension requests are normally claimed due to the following circumstances:

    New orExtra Work not included in the original scope or contract

    Unusual or adverse weather conditions

    Variation order

    Lack of manpower

    Shortage/Unavailability of materials

    Problems Encountered

    In a construction project although every action or activity is thoughtfully planned, still,problems and delays occurred. Problems in the surroundings, setting up the formworks, pouring

    of concrete, placing of reinforced bars and finishing should be considered to come up with a

    good project. During our on-the-job training on Orchard Residences, we encountered different

    kinds of problems and these are:

    One of the major problems that we encountered is the honeycombs. As we can see in the

    picture there are hollow spaces and cavities left in concrete mass on surface or inside the

    concrete mass where concrete could not reach. These look like honey bees nest.

    Honeycomb is due to non-reaching of concrete to all places due to which cavities and

    hallow pockets are created, main reasons are:

    1. Improper vibration during concrete.

    2. Less cover to reinforcement bars.

    3.

    Use of very stiff concrete (this can be avoided by controlling water as

    perslump test).

    4. Places like junction of beam to beam to column and to one or more beams

    are the typical spots where honey combs are observed. This is due to

    jumbling of reinforcement of beams and column rods at one place; special

    attention is required at such place during concreting and vibrating.

    5. Presence of more percentage of bigger size of aggregate in concrete also

    prevents concrete to fill narrow spaces between the reinforcement rods.
