ABSTRACT
This chapter examines the contractor's obligations regarding time, programming and completion under the Royal Institute of British Architects (RIBA) Building Contracts, including the mechanisms for monitoring progress and the sanctions for non-completion. In the RIBA Building Contracts, the extent of the access will be interpreted in the light of all the information made available to the contractor at the time of tender. The contract administrator will not normally intervene in matters concerning the day-today programming. The main reason for including events caused by the client and the contract administrator is to preserve the client's right to liquidated damages. The objective is always to assess what effect the event will have on the final completion date, and the contract administrator should take into account the fact that the contractor should use reasonable endeavours to minimise the effects of any delaying event.
