not be resized or exposed items relocated without the Consulting
Engineer’s approval. No changes shall be made in any wall or chase
locations, ceiling heights, door swings or locations, window or other
openings, or other features affecting the function or aesthetic effect of the
building. The drawing shall indicate all ductwork, grilles, registers,
diffusers, dampers, terminal units, coils, smoke detectors, piping, valves,
sprinkler heads, smoke detectors, light fixtures, access requirements,
access doors, etc. The drawing shall permit the installation of lights and
diffusers at any location on any office story without relocating of
horizontal duct runs or sprinkler piping. If conflicts or interference
require interpretations of the Contract Documents, the Engineer and the
Consulting Engineer’s clarifications shall be obtained. Each Trade shall
use a different color pencil for work on the coordination drawing.
D.
After any conflicts or interferences are resolved, the composite mylar
drawings shall then be signed and dated by each of the Subcontractors,
indicating their awareness of the agreement with the indicated routings
and layouts and their interrelationship with the adjoining or contiguous
work of all Contracts. The drawings shall be maintained in a current
state by the Subcontractors. Thereafter, no unauthorized deviations will
be permitted.
E.
The original composite mylar drawings signed by all Subcontractors
shall be retained by the Subcontractor and be available for examination
and reference by the Owner, Engineer and Consulting Fire Protection
Engineer at any time. Furthermore, copies of these originals shall be
provided at any time if requested by the Engineer.
F.
The Composite Drawings shall not substitute for a Subcontractor’s shop
drawings for the respective Trades which shall be submitted to the
Engineer. The shop drawings, required by Article 1.10, shall accurately
record the agreed Composite Drawings as detailed for the respective
