STANDARD SPECIFICATIONS 23 01 00 – PAGE 6 OF 9
NOVEMBER 2, 2012
3.1 LAYING OUT WORK:
A. The Plans are in part diagrammatic. Contractor shall verify roughin
dimensions with fixture Shop Drawings and with the Architectural Plans.
Conform to dimensions shown on the Plans in preference to scaling from
the mechanical drawings. Provide all fittings and appurtenances required
for proper system operation.
B. Contractor shall allow for thickness of finishes when roughing in his work.
He shall not rough without obtaining accepted Shop Drawings for the
actual equipment to be installed.
C. Due to the scale of drawings, it is not possible to indicate all offsets,
fittings, changes in elevation, etc. which may be required. Make all such
changes in piping, ductwork, conduit system, location of equipment, etc.,
to accommodate work to obstacles encountered, at no increase in
compensation. If requested, submit at least five (5) copies of drawings
detailing all major deviations or changes. All changes must be approved
before installing.
D. Plans show general arrangement of piping and connections. Install work
substantially as indicated. Verify exact locations and elevations on job.
Before installing work, consult other Plans, details and Contractors to
determine headroom and work interferences. Examine Architectural
Plans for exact location of equipment, fixtures and outlets. Where not
definitely located, obtain information from Architect.
E. Thoroughly coordinate work with that of other Contractors. Raise piping
and drip where necessary. Vent all air pockets in water piping, even
though not so indicated. Determine exact route and/or location of each
pipe before fabrication and installation. Furnish in writing to Architect, any
information necessary to permit work of other trades to be installed
properly and without delay. Maintain maximum head room. If plumbing
work cannot be installed at least 7’0” above the f loor (in mechanical
spaces or basement and higher in finished spaces dependent on ceiling
height), consult with the Engineers and obtain approval before
proceeding. If directed by Architect or Engineers, prepare composite
drawings and sections (scale not less than ¼” = 1’), clearly showing
installation of work in relation to work of other trades.
F. Should Architect's details, field conditions, change in equipment or Shop
Drawing information necessitate an important rearrangement, report
same to Engineers and obtain approval before proceeding.
G. Install piping, etc. to avoid interferences with removal of coils, filters, belt
guards or any operating part of all systems, or operation of overhead or
swinging doors. Maintain easy and safe access to valves, controllers,
motor starters, and other equipment requiring frequent operation.
Maintain opening of access doors, switch boxes, motor starters, panel

equipment. Thoroughly instruct contractors' personnel on job, exactly
how their equipment shall be installed, connected, lubricated, started up,
operated, etc., so that all factory instructions are rigidly followed.
B. Install, test, start and operate all equipment only as instructed by
manufacturer and in presence of manufacturer's representative, as
directed. Follow instructions of manufacturer as noted above. Provide

Architect's and Engineer's approval before proceeding with actual
installation of same.

incidental valves, fittings, piping, wiring, etc., not supplied by
manufacturer or other Contractors, for proper apparatus operation
Contractor shall provide accurate information to other Contractors for
required services to equipment, such as water supply and waste
connections, masonry openings, wiring requirements, etc. Such
information shall be complete and correct for particular job.
D. If required by Engineers, contractor shall submit satisfactory evidence
that equipment, systems, etc. have been installed strictly in accordance
with manufacturer's recommendations, have been properly aligned, are
properly adjusted, have been properly tested, lubricated, balanced, etc.
E. As soon as installed, lubricate and leave in good working order, all
motors, bearings, etc., in accordance with manufacturer's instructions.
