Refer to the plans for anticipated quantities. They are included to assist you in developing unit prices and a total lump sum bid, but remain for reference only. Final measured rock excavation quantity that varies from the anticipated quantity on the plans will be added or subtracted from the contract at the unit price. For the other unit prices, if the retaining wall is installed to the size shown on the plans, since it is a lump sum project, slight variations in the quantities for those items will not be added to or subtracted from the contract. Additional “Excavation, Earth” will only be paid for if the planned bottom of excavation as it is currently shown on the plans is determined to have unsuitable soils and the Geotechnical Engineer requires them to be removed to create a suitable bearing surface.

See sections 31 20 00 Earth Moving and 32 32 23 Segmental Retaining Walls for further details on measurement requirements of each unit priced item.
