APPENDIX C

Rectangular Rapid Flashing Beacons (RRFB) Crosswalk System Specification

1 Scope Refer to attached plan drawings for layout details of the/each system.

The system shall consist of two, back-to-back facing RRFB units, each situated at the entrance of each side of the pedestrian crossing, each equipped with a pedestrian activation device, 2 Project Location The system consists of the materials for the installation of a LaneLight RRFB Pedestrian Crossing System to be used for the pedestrian crossing on Beck Avenue near Station 131+00.00 to alert motorists they are approaching an active pedestrian crossing occupied or about to be occupied by one or more pedestrians.

The installer’s responsibilities would consist of installing RRFB system and auxiliary components such as poles, signs, pushbuttons, automatic detection, and the construction of facilities to support the system, as outlined in these specifications and in strict adherence to the manufacturer’s installation requirements as outlined in, but not limited to, the manufacturer’s installation instructions.

3 Installer Responsibilities Several utilities may exist in the area; any and all utilities’ locations shown in any plans should be considered approximate. The installer shall be responsible for calling the appropriate authority and all affected utility companies prior to any drilling or excavation on this project.

The installer shall stake all proposed accessible push button station locations, ground box locations, conduit, and pole locations after utility locations are finalized. The engineer having authority must approve these locations prior to any drilling or excavation on the project.

4 Warranty System components shall have a non-pro-rated warranty period of five (5) years against manufacture defects and failure under normal use.

5 Technical Specifications IMPORTANT: If the installer wishes to submit an alternate system for an approved equal (“equal” is defined herein as meeting or exceeding all the specifications shown in this document), specifications of the proposed alternate that fully conform to the following specifications shall be submitted to the Engineer for approval prior to installation.
