One of our current projects a chain tire store.
The existing building housed a golf store and is approx. 14k SF. Another contractor performed the interior demolition included the multi-level slab where they had various elevations for putting greens.
Our original scope of work is the normal erosion control, exterior demolition, grading, storm and wet utilities including an oil/water separator.
Here's the "fun" part. Concrete sub poured back the 14K SF slab and most of it did NOT meet the flatness numbers in the spec's. Now here's the kicker - the concrete sub and the laser screen sub specifically excluded meeting the flatness numbers in their contract and the PM didn't catch it...
The owner accepted a portion of the slab and refused about 7K SF which had to come out. We got the CO to remove the freshly poured 6" 4K PSI slab with wire and 1/2" rebar. The crew had to work around pit drains for the car lifts, stainless steel imbeds and a trench drain that ran the entire length of the service bay.
I excluded any responsibility for the plumbing, drains, imbeds, electrical conduits and the trench drain. However the crew did a great job and not only left the floor drains in place but salvaged the imbeds and didn't damage the trench drain. The electrical conduits didn't fare as well but they were run on top of the gravel just under the vapor barrier.
Typical retail job - trades on top of each other..

The masons were cool to work with and we moved their pallets of block around with the CTL because the forklift couldn't get in.

My super going back over the trench drain. The drain has a few bumps and bruises but it was to be expected. The crew did a great job.
