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.
2414.04 method of measurement.
Measurement for the various items involved in the construction of railings will be as follows:
1. Concrete Barrier Railing.
Linear feet (meters) shown in the contract documents, measured from end to end of the barrier, including end sections and transition sections. Measurement for the weight (mass) of reinforcement steel installed in the barrier will be according to Article 2404.04.
2. Concrete Open Railing.
Linear feet (meters) shown in the contract documents, measured from end to end of the barrier, including end sections and transition sections. Measurement for the weight (mass) of reinforcement steel installed in the barrier will be according to Article 2404.04.
3. Retrofit Concrete Barrier Railing.
Linear feet (meters) shown in the contract documents, measured from end to end of the barrier, including end sections and transition sections. Reinforcement steel in Retrofit Concrete Barrier Railing will not be measured for payment.
4. Electrical Circuits.
When electrical conduit and junction boxes are installed as part of Section 2525, Article 2525.04 applies; otherwise, electrical conduit and junction boxes will not be measured.
B. Steel Pipe Pedestrian Hand Railing and Structural Steel Pedestrian Hand Railing.
