Article 1 — Description
Furnish and install, relocate, or remove cable barrier systems and cable barrier terminal sections at the locations shown on the plans.
Article 2 — Materials
Furnish new cable barrier systems and cable barrier terminal sections in accordance with the details shown on the plans and in conformance with the manufacturer’s shop drawings, or equal as approved. Cable barrier systems approved for use have passed NCHRP Report 350 or MASH of the test level specified (e.g., TL-3 or TL-4). The post spacing and resulting deflection characteristics of the system will be such that contact with obstructions within the project site will be avoided when the system is impacted. Furnish pre- stretched cable. Furnish Class A concrete in accordance with Item 421, “Hydraulic Cement Concrete.” Furnish delineators as shown on the plans and in accordance with Item 658, “Delineator and Object Marker Assemblies.” Salvage approved material when shown on the plans. When specified, construct cable barrier systems and cable barrier terminal sections using salvaged materials removed within the project site. Incidentals and material necessary to replace unsalvageable materials needed to relocate a cable barrier system or cable barrier terminal section as shown on the plans and in conformance with manufacturer’s recommendations will be furnished by the Contractor.
Article 3 — Construction
Perform work in accordance with the details, dimensions, and requirements shown on the plans and in accordance with manufacturer’s recommendations. Place posts into steel sleeves in a concrete foundation unless otherwise shown on the plans. Locate terminal sections at locations as shown on the plans. Repair or replace damaged parts immediately. Provide an installation and repair manual specific to the cable barrier system an d cable barrier terminal sections. Locate barrier delineators at a maximum spacing of 100 ft. and in accordance with the TMUTCD or as shown on the plans. Install barrier delineators in conformance with manufacturer’s recommendations.
3.1 Install. Provide and install new cable barrier system and terminal section components.
3.2 Relocate. As shown on the plans, remove existing cable barrier system and cable barrier terminal sections
and install at another location. Completely remove posts and any concrete surrounding the posts. Furnish new foundation concrete. Furnish backfill material and backfill holes with material equal in composition and density to the surrounding soil unless otherwise directed. Repair or replace Contractor damaged material at the Contractor’s expense as directed.
3.3 Remove. Remove existing cable barrier systems and cable barrier terminal sections from the project site.
Properly dispose of unsalvageable materials in conformance with federal, state, and local regulations. Completely remove posts and any concrete surrounding the posts. Furnish backfill material and backfill the holes with material equal in composition and density to the surrounding soil unless otherwise directed. 824 As shown on the plans, salvage cable, posts, terminal sections, and hardware to be retained by the Department. Neatly stack salvaged materials and deliver to designated sites shown on the plans. Concrete foundations and steel post inserts will be considered unsalvageable material. Repair or replace Contractor damaged salvageable material at the Contractor’s expense. Do not mar or damage salvageable materials during removal.
Article 4 — Measurement
4.1 Install. Measurement will be by the foot of cable barrier system and by each cable barrier terminal system
installed.
4.2 Relocate. Measurement will be by the foot of cable barrier system and by each cable barrier terminal system
relocated.
4.3 Remove. Measurement will be by the foot of cable barrier system and by each cable barrier terminal system
removed.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid under this Article. Delineators attached to the cable barrier will not be measured or paid for directly but will be subsidiary to this Item.
5.1 Install. Payment will be made for the unit price bid for “Install Cable Barrier System” of the test level
specified (e.g., TL- 3 or TL- 4), “Install Cable Barrier System” of the test level specified (e.g, TL- 3 or TL- 4) and post spacing specified, and “Install Cable Barrier Terminal Section” of the test level specified (e.g., TL- 3 or TL-4). The unit price bid for “Cable Barrier System (Install)” and “Cable Barrier Terminal Section (Install)” is full compensation for furnishing cable barrier system, cable barrier terminal section, concrete foundations (excluding mow strips), delineators, equipment, labor, tools, and incidentals.
5.2 Relocate. Payment will be made for the unit price bid for “Relocate Cable Barrier System” of the test level
specified (e.g., TL- 3 or T L-4), “Relocate Cable Barrier System” of the test level specified (e.g., TL- 3 or TL- 4) and post spacing specified, and “Relocate Cable Barrier Terminal Section” of the test level specified (e.g., TL-3 or TL- 4). The unit price bid for “Cable Barrier System (Relocate)” and “Cable Barrier Terminal Section (Relocate)” is full compensation for relocating existing cable barrier system and cable barrier terminal sections on the project site from one location to another (including disassembly and reassembly costs), moving material to a temporary storage area (including disassembly costs), and moving and installing cable barrier system and cable barrier terminal section material from a temporary storage area to an installation site on the project. This price includes furnishing steel post inserts, concrete foundations (excluding mow strips), delineators, backfilling holes, equipment, tools, and incidentals.
5.3 Remove. Payment will be made for the unit price bid for “Remove Cable Barrier System” and “Remove
Cable Barrier Terminal Section.” The unit price bid for “Cable Barrier System (Remove)” and “Cable Barrier Terminal Section (Remove)” is full compensation for salvaging or removing and disposing of cable barrier system, cable barrier terminal sections, concrete foundations (excluding mow strips), delineators, backfilling holes, equipment, labor, tools, and incidentals.
