Contractor shall be responsible for installation of systems according to the true intent and meaning of Contract Documents. Anything not clear or in conflict will be explained by making application to Owner’s Representative. The Contractor shall familiarize himself with his scope of work as well as the required coordination with other trades and the scheduling of other trades sufficiently to address coordination issues in a timely manner such that they do not result in remedial work for other trades.

B. Should conditions arise where certain changes would be advisable, secure approval from Owner’s Representative for those changes before proceeding with work. Proceeding without written approval is at the Contractor’s risk and at the Contractor’s expense.

C. The contractor shall coordinate with the work of various trades when installing interrelated work.

Before installation of mechanical items, proper provisions shall be made to avoid interferences.

D. Permission to use Division 20 and 23 systems or equipment for temporary heating or other contractor use prior to the Date of Acceptance, as outlined elsewhere in these specifications, shall not constitute the beginning of the guarantee period. The contractor shall make any necessary arrangements to extend equipment and/or system warranties sufficient to maintain the designated guarantee period from the Date of Acceptance.

1. Exception: When temporary heating and or other system use is requested by the Owner for the Owner’s benefit prior to the Date of Acceptance, the guarantee period for the portions of the system or specific equipment requested for use may begin at the time it is put into service.
