RONALD REAGAN WASHINGTON NATIONAL AIRPORT
PROJECT DT1203
1. Coordinate electrical systems, equipment, and materials installation with other building
components and trades.
2. Verify all dimensions by field measurements.
3. Coordinate the installation of required supporting devices and sleeves to be set in pouredin-place
concrete and other structural components, as they are constructed.
4. Sequence, coordinate, and integrate installations of materials and equipment for efficient
flow of the work.
5. Where mounting heights are not detailed or dimensioned, install systems, materials, and
equipment to provide the maximum headroom possible.
6. Coordinate connection of electrical systems with exterior underground and overhead
utilities and services. Pay particular attention to requirements for access and service of
the equipment in choosing final equipment locations. Comply with requirements of
governing regulations, franchised service companies, and controlling agencies. Provide
required connection for each service.
7. Install systems, materials, and equipment to conform with approved submittal data,
including coordination drawings, to the greatest extent possible. Conform to
arrangements indicated by the Contract Documents, recognizing that portions of the work
are shown only in diagrammatic form. Where coordination requirements conflict with
individual system requirements, refer conflict to the COTR.
8. Install systems, materials, and equipment level and plumb, parallel and perpendicular to
other building systems and components, where installed exposed in finished spaces.
9. Install electrical equipment to facilitate servicing, maintenance, and repair or replacement
of equipment components. As much as practical, connect equipment for ease of
disconnecting, with minimum of interference with other installations.
10. Install access panel or doors where units are concealed behind finished surfaces.
11. Install systems, materials, and equipment giving right-of-way priority to systems required
to be installed at a specified slope.
B. All wiring, including low voltage wiring outside boxes and enclosures, which is not installed in
a raceway or duct bank, shall be installed in electric metallic tubing (EMT) conforming to UL
797. Minimum size shall be 3/4-inch unless otherwise shown or approved by the COTR. All
electrical work shall be as specified in Division 26 Electrical Sections, and as shown.
Grounding shall be installed as necessary to preclude ground loops, noise, and surges from
adversely affecting system operation.
C. Maintain consistent color-coding for all wiring/cabling in accordance with the approved shop
drawings and as specified herein.
D. Power line surge protection: All equipment connected to alternating current circuits shall be
protected from power line surges.
E. Device wiring and communication circuit surge protection: Copper wire inputs and outputs
shall be protected against surges induced on communication and device wiring.
3.4 CONNECTIONS
A. All connections of stranded wire to screw terminals shall be by insulated spade lugs, crimp
fastened to wire or as specified otherwise.
