    QQQ AAA TTT AAA RRR

    1. SCOPE

    This QC Procedure defines the type and extent of inspection and testing to be carried out to verify all operations involved in the Erection of Formworks, Fixing of Rebar and Placing, Curing, Repair and Protection of concrete during construction and commissioning works.

    2. PURPOSE

    This Quality Control Procedure defines the documentation to be collated and the inspections to be carried out in order to verify and record that all concrete works activities are conformant to the requirements in the Project Specification.

    3. HSSE All works shall be in compliance with the State of Qatar laws and regulations, Ras Laffan Industrial City and International standards, codes, Linde Engineering AG and QSGTL and/or its PMC requirements and instructions. In addition all employees and Gama subcontractor employees on site will have through Linde Engineering AG Site Safety Induction and Gama Qatar Safety induction for site safety, health, environmental and security prior to work activities. Other training courses will be attended as required by Linde Engineering AG or QSGTL and/or its PMC as required. At a minimum a Risk Assessment will have been prepared by the Risk Assessment Team (RAT) ranking the hazards associated with project works and control measures to be taken to mitigate the hazards to an acceptable level. Each work scope or task will have a completed and approved Job Safety Analysis (JSA) identifying the potential hazards and control measures that will be implemented to protect people and environment. Supervisor as the basis of conducting his daily Pre-Task meeting and his weekly Tool Box Talk (TBT) will use the JSA. In addition to the above, employees conducting survey works will wear required PPE and highly visible vest where traffic or other hazards may exist. For additional safety requirements for a particular or specific task please refer to the JSA prepared for that task.

    8.3. POST POUR ACTIVITIES

    8.3.1. General

    The QC will ensure that immediately after finishing all exposed concrete surfaces are properly protected and covered with white polyethylene sheet with the edges lapped or tied down to exclude air circulation. After the concrete has stiffened but no longer than1 hours, the polyethylene sheet shall be removed and replaced with a Hessian soaked with water. The polyethylene sheet shall be placed over the Hessian immediately, to protect evaporation. Throughout the curing period, the Hessian shall be maintained in a permanently wet condition using mix quality water, curing shall continue for a minimum of 10 days for all concrete.

    After the completion of curing period, location of embedded items and Anchor bolts shall be verified and recorded.

    8.3.2. Finishing Above ground concrete finish shall be Class 1 as defined in BS 8110-1 section 6.2.7.2 Below ground concrete finish shall be Class 2 as defined in BS 8110-1 section 6.2.7.2

    8.3.3. Testing Compression Test shall be as per T-13.376.358 Section 3.33 Frequency requirement; For pours up to 10cu.m Once For pours up to 20cu.m Twice For pours over 20cu.m Every 20 cu. m but not less than twice For pours over 200cu.m Every 40 cu. m

    8.3.4. Concrete repairs and Tolerances

    Immediately after forms are removed, exposed surfaces shall be inspected. Small holes and minor honeycombing which do not impair the strength with a maximum size of 10 mm x 10 mm shall be filled with company approved material, which shall be essentially the same composition as the surrounding concrete. Members having extensive defects shall be repaired or replaced as per approved method statement for the particular repairs.

    Tolerances in variations/deviations shall be accordance with the project specifications.

    No other repairs will be permitted without the approval of the Contractor / Company.

    The QCI will inspect the installation of rebar in a systematic manner such that all necessary points of surveillance are adequately monitored at each stage of the process.

    Routine surveillance shall comprise inspection to confirm that:

    All on-site storage is sufficiently off-ground; bundles are properly stored and separated.

    All bundles of fabricated rebar are adequately and correctly tagged for identification.

    The latest revision of the relevant Drawings is being used.

    The bar codes, sizes and numbers are as shown on the Drawings.

    The lap lengths are as shown on the Drawings.

    The correct type of tie wire is being used, all ends are bent inwards and sufficient intersections are being tied to ensure rigidity.

    APPENDIX B: Inspection of the Erection of Formwork

    The QCI will inspect the erection of formwork in a systematic manner such that all necessary points of surveillance are adequately monitored at each stage of the process, where applicable (columns, etc) formwork will not be closed until the reinforcement steel has been checked.

    Routine surveillance shall comprise inspection to confirm that: All materials are in an adequate condition.

    Boards in shutters and adjacent shutters are properly aligned and sealed-over (as necessary).

    All grooves, corner chamfers, etc. properly installed.

    Shutter surface clean, sound and coated with an approved Release Agent.

    Hatches, and Box-Outs and Inserts to be affixed to the formwork are correctly positioned.

    Kickers correctly positioned (also checked rebar starters relative to kickers).

    Tie-rods and support systems appear to be satisfactory.

    Where required, templates properly installed.

    Where required, water stops and bars, etc. are properly installed.

    Top level battens/screed-boards properly installed.

    Surveyor's checked, completed and within tolerances.

    Plumb-bobs installed (where required).

    Area adequately cleaned-out.

    At the time of final inspection the QCI will proceed in general accordance with the above, but with particular emphasis on any points, which had previously been observed as requiring in-process rectification.
