Furnish and install formed steel beam guardrail for bridge structures or approaches according to the contract documents and Section 2505. Use structural steel posts furnished and installed as part of the bridge structure for rails on new bridge structures.

 

E.    Aluminum Pedestrian Hand Railings.

Construct aluminum hand railings with aluminum posts supporting rails of aluminum tubing according to the contract documents and the following:

 

1.     Handling and Storage.

a.     Carefully handle and store aluminum posts and rails at the work site. Do not store aluminum parts in contact with the ground or where they may be attacked by acid or alkali.

b.     Replace members which are marred or damaged to the extent that their usefulness or appearance is impaired at no additional cost to the Contracting Authority.

 

2.     Installation.

a.     Set anchor bolts in the concrete curb at the correct location and elevation. Hold them firmly in place using suitable templates that will insure their correct position during placing and hardening of the concrete.

b.     Assemble and align the rails. If necessary, shim the rails to bring them to the correct elevation. Tighten anchor nuts to hold the rails firmly in place. After aligning the rails, position them to accommodate the anticipated expansion. Tighten the setscrews to hold the rails firmly in place. Cap the ends of tubular rails.

c.     After erection, carefully remove all dirt and grease from the rails, posts, and concrete around the post base using a cleaning method the Engineer approves.
