Coordinate the conduit installation with other trades and the actual supplied equipment. Obtain information relevant to the placing of electrical work and in case of any interference with other work, proceed as directed by the Owner/Engineer and furnish all labor and materials necessary to complete the Work in an approved manner, at no additional cost to Owner/Engineer. Submit conduit layout drawings a minimum of four weeks prior to installation of raceway.

GREAT LAKES WATER AUTHORITY BASIC ELECTRICAL REQUIREMENTS

PW\DEN003\C6A18000 26 05 02 - 4

B. Check approximate locations of light fixtures, switches, electrical outlets, equipment, and other electrical system components shown on Drawings for conflicts with openings, structural members, and components of other systems and equipment having fixed locations. In the event of conflicts, notify Engineer in writing. Any adjustments required in the field shall be provided at no additional cost to the Owner/Engineer.

C. Install work in accordance with NECA Standard of Installation, unless otherwise specified.

D. Keep openings in boxes and equipment closed during construction.

E. Lay out work carefully in advance. Do not cut or notch any structural member or building surface without specific approval of Engineer. Carefully perform cutting, channeling, chasing, or drilling of floors, walls, partitions, ceilings, paving, or other surfaces required for the installation, support, or anchorage of conduit, raceways, or other electrical materials and equipment. Following such work, restore surfaces to original condition.

F. Where circuits are shown as “homeruns” all necessary fittings and boxes shall be provided for a complete raceway installation.

G. Circuit layouts are not intended to show the number of fittings, or other installation details.
