World Bank Standard Bidding Documents: Procurement of Works Smaller Contracts

These Standard Bidding Documents are intended as a model for admeasurement (unit prices or unit rates in a bill of quantities) and lump sum types of Contract, which are the most common in Works contracting. Lump sum contracts are used in particular for buildings and other forms of construction where the Works are well defined and are unlikely to change in quantity or specification, and where encountering difficult or unforeseen site conditions (for example, hidden foundation problems) is unlikely. The main text refers to admeasurement contracts. Alternative clauses or texts are supplied for use with lump sum contracts.
