This interfacing will occur throughout all the phases of the project and will include the need for others to access the Site. The Contractor shall allow in his Contract price for this interface specification, including registers, management, preparing for, attendance at, and following up interface meetings as required, and impact on progress during execution.

Contractor shall provide all appropriate interface data for input into Companys integrated planning system.

The Contractor shall prepare and maintain a register of interface related issues and shall actively expedite the resolution of all such issues.

Contractor shall develop contingency plans, including measures to be taken, if any of its planned activities cannot be executed due to late completion of activities by other parties.

Contractor shall, within seven days of occurrence, inform Company in writing of any delay caused by late completion by Other Contractors. Contractor cannot claim delay caused by late receipt of interface information i.e. should the required date expire, then the Contractor is to reasonably make an assumption about the information expected from the interface party, advise Company and proceed accordingly.

Contractor shall ensure that during all phases of the Work areas of interface with activities of Company or others are properly managed.
