 7.0         QUALITY CONTROL PROCEDURE

7.1      GENERAL

            The inspection and testing procedure shall be governed by the specifications, approved construction drawings, related codes and standard. Joint inspection shall be carried out between the relevant parties.

            Inspection Request Form (IRF) shall be issued at least 24 hours prior to the commencement of the works. Results of the inspection shall be recorded in the Inspection Checklist and shall be signed by respective consultant during the inspection.

7.2       MATERIAL QUALITY REQUIREMENT

            All materials must comply with the requirement stated in the specifications, approved construction drawings, related codes and standards. This is to ensure the quality and standard of the works are adhered.

8.0       PREPARATORY WORKS

8.1       GENERAL

i.           Obtain approved architectural drawings, type, specification, colour and pattern for concrete imprint from the client / client’s representative.

ii.          Obtain material submission approval from the resident architect.

iii.         Set out the locations, panel edge lines and levels for formwork along with reference lines.

iv.        Prepare necessary formwork panels to the required dimensions and sizes.

v.         Coat formwork surface evenly and thinly with release agent.

9.0       WORK METHODOLOGY

          9.1    FORMWORK

i.           Erect the formwork by providing sufficient struts including necessary bracing.

ii.          Seal gaps in formwork to avoid leakage of concrete.

iii.         Check for the required dimensions as per drawings.

                                                                                          

       9.2   REINFORCEMENT

i.           Cut the BRC to place it with spacer blocks with required dimensions and shape.

ii.          Place BRC as per drawings and tie them together using GI wire stands.

iii.         Ensure proper lapping and sufficient lap length as per specifications.

iv.        Submit Request for Inspection Form for joint inspection with client / client’s representative using Pre-Concreting Works Inspection Checklist.

v.         On completion of joint inspection, request client / client’s representative to sign on the Request for Inspection Form and file as per Project Filing Index.

                            

           9.3    CONCRETING WORKS

i.           Take concrete cube samples for quantity specified in the contract document.

ii.          Mark the location of pour for concrete received on the delivery docket and checklist as reference and identification.

iii.         Provide adequate equipment, machinery and manpower to carry out the concreting works.

iv.        Place concrete on designated locations using mobile crane/excavator with concrete buckets.

v.         Start concreting from a fresh location or a predetermined construction joint and continue uninterrupted up to the next predetermined construction joint or expansion joint.

vi.        If concreting is to commence from a construction joint, roughen the joint before placing the concrete when wire mesh is not available.

vii.       Compact concrete by mechanical vibrators. Ensure that concrete is worked into the corners of the structural members.

viii.      Once concrete is about to set, apply colour cement (hardener) to the concrete surface and then stamping with concrete mould as per manufacture requirement.

ix.        Carry out curing works by applying high efficiency curing compound.

x.         Forming the grooved lines/joints by sawing the hardened concrete with a diamond impregnated rotary bladed machine. Then install sealing compound onto the grooved lines/joints as per specification

xi.        Submit Request for Inspection Form for joint inspection with client / client’s representative using Post-Concreting Works Inspection Checklist.
