511.01 Description.
This Section shall cover the work of furnishing and installing elastomeric bearings for all types of bridge girders. An elastomeric bearing shall consist of at least a single layer of elastomer and may consist of a possible combination of elastomeric layer(s), internal steel sheet laminate(s), PTFE layer, bearing and/or sole plates, and a stainless steel plate.
511.02 Materials.
Elastomeric bearings shall be fabricated to conform with the material requirements given on the Plans and in Section 837.
511.03 Construction Requirements.
Unless noted otherwise on the plans or in these specifications, Shop Drawings for the elastomeric bearings shall be subm itted to the Bridge Engineer for approval. Shop Drawings will not be required for the elastomeric bearings for precast concrete bridge components furnished under Section 512. The elastomeric bearings will be identified on the plans by Type (Type 1, 2, 3, 4 , or 5) and may be further identified by a Mark (Mark B1, B2, VB1, etc.). Rust that occurs on the portions of bearing plates that are left ungalvanized for welding shall be cleaned to bare metal prior to welding. All exposed surfaces of the sole plate, all uncoated surfaces of the bearing plate and all weld metal shall be coated after welding with galvanizing repair paint that meets the requirements given in SECTION 855.
511.04 Method of Measurement.
The elastomeric bearings will be measured per each for each type of bearing. The bearings measured for payment do not include the randomly selected samples for testing.
511.05 Basis of Payment.
a.Unit Price Coverage . The unit price bid per bearing shall include all costs for equipment, materials (including b earing plates, sole plates, PTFE, and stainless steel plates), cleaning, painting, labor, bearings furnished for sampling and testing, shop drawings, and all incidentals necessary to furnish and install the complete bearing assembly.
b.Payment will be ma de under Item No .: 511-A Elastomeric Bearing Type * (Mark ** ) - per each * Bearing Type (1, 2, 3, 4, or 5) ** Optional Bearing Mark (B1, B2, VB1, etc.) SECTION 512 PRECAST NON-PRESTRESSED CONCRETE BRIDGE MEMBERS
512.01 Description.
This Section shall cover the work of furnishing and installing precast non -prestressed concrete bridge members.
