PART 3 EXECUTION
3.1 INSTALLATION

A. Inspect areas to receive Grating for obstacles. Notify the Engineer of conditions that would adversely affect the installation or subsequent utilization of the areas. Do not proceed with installation until unsatisfactory conditions are corrected.

B. Install Grating according to manufacturer’s recommendations and as shown on the construction drawings.

C. Postion Grating sections flat and square with ends bearing minimum 1-1/2” on supporting structure.

D. Keep sections at least ¼” away from vertical steel sections and ½” from concrete walls.

E. Allow clearance at joints between sections of maximum ¼” at side channels and maximum 3/8” at ends.

F. Band random cut ends and diagonal or circular cut exposed edges with a minimum 1/8” thick bar welded at contact points.

G. Join abutting walkway sections with manufacturer supplied splice plates; bolted or welded as specified.
