One price per core never fits every slab

Anyone who buys core drilling knows the per-core quote. One price per hole, easy to check, easy to sign. Then the slabs are thicker than the quote assumed, a few big openings carry the cost, and the sub reprices it on site.

One case on our Try page: a coring unit price schedule for an office building, next to the sub's per-core quote. Yesper priced by diameter range and slab depth instead. The big ones, 9% of the penetrations, carry 27.5% of the cost, and the quote, built for slab depths most of the penetrations exceed, came out above the schedule.

You sign a schedule that fits your slabs, and the rows the sub would reprice show up before the award, not on site. Same for the rest of the Try page: a quote against the bid schedule, cost by building element, quantities from an IFC model.
