20.4.2
Design Development Submission
20.4.2.1 Drawings: Submit the following drawings developed to the percentage
completion indicated or showing the information indicated:
NOTE: On small or uncomplicated projects, one or more plans may be combined
onto the same sheet, but never so that the plans will be crowded or
information unintelligible. (Drawings are reduced half-size by the government
for bidding.)
a) Existing Site and Removal Plan (90% complete) (may be combined with
Civil Existing Site and Removal Plan for small, uncomplicated projects):
1) Show all existing site information such as buildings,
pavements and utilities which interface with the removal of electrical work.
Indicate the point of disconnection for exterior feeders/services when
facilities are to be removed. (NOTE: WHEN NEW BUILDINGS ARE BEING LOCATED ON
TOP OF EXISTING ELECTRICAL DUCTS, THE CIRCUITING SHALL BE REROUTED AROUND THE
BUILDING SITE. CABLES IN DUCTS TO BE DISCONNECTED SHALL NOT BE ABANDONED.
THE CONTRACTOR SHALL BE DIRECTED TO REMOVE EXISTING CABLES BACK TO THE POINT
OF DISCONNECTION.)
2) Show all electrical removals cross referenced to a legend.
Show estimated quantities for electrical removals not otherwise obvious. Do
not use statements such as "remove all"; give the estimated quantity. The
construction contractor must be able to bid the work without the need to visit
the site. (Removed features should not be shown on subsequent drawings. Show
interior electrical removals on a separate plan.)
b) Electrical Removal Plan(s) (90% complete): Show the complete extent
of all interior electrical removals. See statements above regarding exterior
electrical removals. (NOTE: EXISTING INTERIOR WIRING SHALL NOT BE ABANDONED.
