CONCRETING WORK
OBJECTIVE
Method on how the concreting works are carried out
MATERIALS
Ready mixed concrete
PLANT, MACHINERY AND EQUIPMENT
Tower crane / Mobile Crane, Concrete Pumps, Concreting Buckets, Vibrators, Wheelbarrows, etc. as applicable
PREPARATORY WORKS
1. Request for design mix based on the concrete grades specified on structural drawings from the Ready Mixed Concrete Supplier(s).
2. Submit the proposed design mix to client / client’s representative for approval.
3. Submit request for inspection of structural members with client / client’s representative prior to concreting works using Structural Work (Reinforcement / Concrete) Inspection Checklist and Inspection and Test Plan.
4. Carry out receiving inspection of ready mixed concrete as per Material Receiving Inspection Checklist.
5. File completed Material Receiving Inspection Checklist as per Project Filing Index.
WORK METHODOLOGY
1. Take concrete cube samples for quantity specified in the contract document.
2. Mark the location of pour for concrete received on the delivery docket and checklist as reference and identification.
3. Provide adequate equipment, machinery and manpower to carry out the concreting works.
4. Place concrete on designated locations using concrete pumps and / or crane assisted concrete buckets.
5. Start concreting from a fresh location or a predetermined construction joint and continue uninterrupted up to the next predetermined construction joint or to completion.
6. If concreting is to commence from a construction joint, roughen the joint before placing the concrete when wire mesh is not available.
7. Place concrete from the lowest point to the final concrete level in one operation in horizontal layers.
8. Compact concrete by mechanical vibrators. Ensure that concrete is worked into the corners of the structural members.
9. After the concrete has set, carry out curing works by applying curing compound.
