SUPERINTENDENT'S CHECKLIST
 

1. Concrete Basics
2. Concrete Footings
3. Concrete Slabs on Grade
4. Concrete Walls, Slabs, Beams and Columns
5. Concrete Stairs
6. Precast Concrete

Concrete Basics:

1. What concrete mixes are specified for the project? For what elements?
2. Are there any admixtures or additions to the mixes? When are they to be used?
3. What is the concrete testing plan?

Concrete Footings:

1. What is the best building pad grade (elevation) to have for footing excavation?
2. Will the footing layout use batter boards, offset hubs or some other method?
3. Does the footing layout include enough room for the excavation equipment to work without destroying the layout?
4. How will the excess material from footing excavation be handled?
5. How will water, mud, etc be handled at this stage?
6. Where may Ready Mix concrete trucks wash out their mixers and chutes?
7. Where does any extra concrete from a truck get placed?
8. How will the concrete footing top elevations be set during concrete placement? Will the proposed method give acceptable top of footing results?

Concrete Slabs on Grade:

1. Where are the isolation joints, control joints, contraction joints located? Does this arrangement make sense? Is it likely to work well? Has expansion and contraction been considered in the A/E Drawings?
2. Is trench backfill responsibility clear? Will backfill under slab trenches be tested?
3. Who is responsible for sub-base leveling?
4. Hot weather/cold weather placing requirements approved?
5. Curing method approved?
6. Special floor finishes & slab alignments

Concrete Walls, Slabs, Beams & Columns:

1. Forming and tie method approved? Tie patching?
2. Joint details clear and constructible?
3. Type finish required? Stripping time?
4. Curing method approved?
5. Where do the congestion (where a lot of rebar comes together) and trouble areas seem most likely?

Concrete Stairs:

1. When should stairs be started in the Project?

Precast Concrete:

1. Other trades to review Shop Drawings?
2. Review connections, caulking, sealing?
3. Special tolerances or guaranteed openings?
