PART 1 GENERAL
1.1 PROVISIONS:
A. The Plumbing Specifications are subject to all the requirements of the General
Conditions of the Contract and Specifications and shall be used in conjunction
therewith. The Plumbing Contractor shall refer to other divisions of the Drawings and
Specifications for work which must be carried on in conjunction with the Plumbing
work so that the construction operations can proceed without harm to the Owner for
interference, delay or absence of coordination.
1.2 DRAWINGS AND SPECIFICATION COORDINATION:
A. Drawings and specification indicate the extent and general arrangement of the
Equipment and systems, and intend to provide the Owner with complete, functioning
systems under this Contract.
B. Should conditions necessitate a rearrangement of piping, ductwork, equipment, etc.,
such departures and the reasons, therefore shall be submitted to the Architect by the
Contractor for approval, in the form of detailed drawings showing the proposed
changes. No such changes shall be made without the prior written approval of the
Engineer. Equipment and piping arrangements shall provide adequate and acceptable
clearance for entry, servicing and maintenance.
C. Drawings and Specifications shall be considered as cooperative, and work or materials
called for by one and not mentioned in the other shall be done and furnished as though
treated by both.
D. In the case of insufficient information and discrepancies in figures, dimensions, details,
Drawings, Specifications, or construction notes, the Architect shall be notified
immediately and his decision shall determine the necessary adjustment. Without such
decision, said discrepancies shall not be adjusted by the Contractor. In case of any
settlement or any complication arising from such adjustment to the Contractor, he shall
bear all extra expense involved. There shall be no additional expense to the Owner,
Architect or Engineer.
E. Should it appear that the work intended to be done, or any of the matters relative
thereto, are not sufficiently detailed or explained on the drawings or specifications, the
