PLANNING AND PROGRESS OF WORK

Planning of Work

The works shall be carried out and completed in accordance with the Contract completion date stated below. The Contractor shall submit a Plant Manufacture, Delivery and Erection Programme for the approval of the Engineer.

Three copies of the above mentioned Programme shall be provided by the Contractor.

If at any time during the execution of the Contract the Contractor finds it necessary to modify any approved Programme, the Contractor shall inform the Purchaser immediately and submit a modified Programme for his approval. The submission of a modified Programme shall not have effect as a claim by the Contractor for an extension of time for completion as provided by the Conditions of Contract, nor shall the approval of such modified Programme have effect as the grant of such extension of time fixed by the Contract for the completion of the Works.

Progress of Plant Manufacture in Contractor's Works

Progress of manufacture in relation to the detailed Plant Manufacture and Delivery Programme shall be reported on an approved form at such frequency as may be required.

Access to the Contractor's and Sub-contractor's works shall be granted to the Purchaser at any reasonable time for the purpose of ascertaining progress and checking quality.

Progress of Work on Site

Progress of Site Work in relation to the detailed Plant Erection Programme shall be indicated on an approved form and submitted monthly or at such other intervals as required by the Purchaser. These submissions shall include a schedule of Site Labour.

Delivery and Take-over Dates for Completed Work

Confirmation is required that the Tenderer can meet the following proposed Dates:

Factory Acceptance Dates

Take-over Dates

Damages for late delivery shall apply in accordance with Terms and Conditions.
