Item Description

PREAMBLE TO BILL OF QUANTITIES Tenderers are reminded that the works carried out under this Contract require pedestrian and vehicular access areas along all adjacent roads to be maintained at all times as indicated in Volume A, Preliminaries and Contract Conditions. The Contractor is deemed to have included in the rates for undertaking the works and providing the necessary equipment to meet the requirements of the Contract. The Contractor is to allow in his rates/prelims for access equipment to enable all repairs/decoration to be carried out externally to brickwork and timber also to internal decoration. It is deemed included that the Contractor shall have allowed in his rates for the delivery, including transportation, storage and handling the items. The location of the site is such that there are restrictions on the weight and dimensions of plant accessing the site. It is deemed, included that the contractor has allowed for such restrictions in determining the nature of plant which is to be used on the works. Furthermore, the limited access suffers from congestion at peak times and the contractor should allow for this in his rates.
