A payment method used on one Medina County, Ohio, whitetopping takes some of the guesswork out of estimating and bidding concrete overlays. For most concrete paving contracts, bid and pay quantities are on a square yard basis. To be fair to both taxpayers and the contractor, county officials based pay quantities on both square yards paved and cubic yards of concrete used. The square yard payment was for placing, jointing, sealing joints, curing, and embedding items. The cubic yard payment was for cost of the concrete.
