Very important question before providing clearances to pour concrete. I would follow following steps.
- Ensure Contractor has bar bending schedule and approved drawing.
- Ensure reinforcement used are approved grade and test certificates are in place.
- Check diameter of rebar ( reinforcement)
- Check spacing
- Check banding radius
- Check number of bars
- Check laps are of proper length. Some time couplers are used to join the reinforcement. Couplers must be approved.
- Check proper cover to rebar is in place.
- Covers should be approved
- Check the reinforcement installed does not sag or move. For this ensure you use chairs.
- Tie the rebars together using soft annealed lining wire and turn the know inside.
- Reinforcement must be clean without any dirt or coating.
- Some time special reinforcement steel is provided around openings. Ensure this is in place.
- It is normal for QC departments to use check lists for this.
Hope this helps.

Lumpsum
A lumpsum contract (or specified total agreement) is the customary method for acquiring development and still the most well-known type of development contract. Under a singular amount contract, a solitary ‘single amount’ cost for all the works has concurred before the works start. This is commonly fitting where the venture is very much characterized, when tenders are looked for, and noteworthy changes to necessities are impossible. This implies the temporary worker can precisely value the works they are being approached to complete. Lumpsum contracts may be less suitable where speed is significant, or where the idea of the works isn’t very much characterized. Different types of agreement that may be increasingly suitable in such conditions incorporate estimation contracts (utilized where the works can be depicted in sensible detail, yet the sum can’t), cost repayment contracts (utilized where the idea of the works can’t be appropriately characterized at the beginning, frequently utilized where a prompt beginning nearby is required), target cost contracts, etc.

Provisional Sum
The term ‘provisional sum’ is commonly surely known in the development business. It is utilized in valuing development agreements to allude either to work which is really temporary, as in it could conceivably be done by any means, or to work whose substance is unclear, with the goal that the gatherings choose not to attempt to value it precisely when they go into their agreement. A provisional sum is typically included as a round figure surmise. It is incorporated scientifically in the first agreement cost; however, the gatherings don’t anticipate that the underlying round figure should be paid without modification. The agreement normally gives explicitly how it is to be managed. A typical statement in substance accommodates the temporary whole to be discarded, and a fitting valuation of the work really did to be fill in for it. In this general sense, the term ‘temporary aggregate’ is near a term of workmanship, yet its exact significance and impact rely upon the conditions of the individual agreement.
