Expected repair percentage on formed walls/columns
Expected repair percentage on formed walls/columns
(OP)
We are being asked to mediate between developer and concrete forming sub (there is no GC), project is a big box retail centre. Some foundation walls are exposed such as loading dock areas, but there was no 'architectural specification'. Contractor has filled tie holes, patched/rubbed and done grinding of fins/joints etc. There must be some allowance carried by concrete contractors to cover 'expected' repairs. Contractor is looking for extras, the owner is 'expecting perfection', and hanging onto holdback.
Any thoughts?

beton1: Now this sounds familiar. The owner wants smooth as a baby's butt, and the contractor bid as-cast concrete. What ACI document was referenced in the specs? Visible concrete does not necessarily mean "Architectural Concrete" - been there with utility & boiler rooms. For foundation walls I would expect plugged tie holes (if the ties had cones), projecting fins knocked off, and excessively large bug hole & superficial honeycombing to be patched. Period, no more.
If ACI 301 was the reference spec document, then that's the most any concrete contractor would offer. Now, if ACI 303.1-97 was a referenced document, it becomes a whole other matter...
Why is it always the contractor's fault when the Architect did a poor job at moderating the owner's expecations or didn't necesessarily convey the correct intent via the contract documents?

pays extra. Is this percentage a reasonable number to at least get negotiations going?

For buried work, the ties ends are broken off, maybe the tie holes get plugged, and major honeycombing get repaired. Fins are left untouched.
At the loading dock, visible wall surfaces would have the ties ends broken off, the tie holes plugged, projecting fins knocked off, major bug holes & superficial honeycombing get patched, and seriuos honeycombing gets repaired.
As far as a $ amount, I wouldn't attempt to put a number on it based on contract amount (it's just not the right way to evaluate it). It really needs to a manhour quantity based upon the surface area of wall forming. You need some input from a forming contractor who has a better grasp of current production rates and costs than I have.
