- 1240BJ22R0003
About this file
This solicitation is for a Multiple Award Task Order Contract to provide road construction services throughout Alaska. The scope of work includes new road construction, road reconstruction, bridge construction, trail construction, culvert installation, erosion control activities, and road demolition. Major work categories involve clearing, earthwork, drainage, aggregate production and placement, construction and demolition of road and bridge structures, retaining walls, and emergency road reconstruction. Contractors must have appropriately certified personnel and equipment to complete tasks identified in individual task orders, which will provide additional project details, specifications, and requirements. This indefinite delivery/indefinite quantity contract establishes basic terms for the Forest Service to issue future task orders for road construction and maintenance projects over the life of the contract.

MATERIALS: USE STEEL SHAPES, PLATES AND BARS SHALL BE STRUCTURAL STEEL CONFORMING
TO AASHTO M270, GRADE 36, EXCEPT FOR STRUCTURAL TUBING USE ASTM A500 GRADE B, OR
ASTM A501. GALVANIZE STEEL SHAPES, PLATES AND BARS IN ACCORDANCE WITH AASHTO M111
(ASTM A123) IF NOT COVERED BY 1 INCH OR MORE OF CONCRETE. USE W-BEAM GUARDRAIL,
THRIE BEAM GUARDRAIL AND ASSOCIATED HARDWARE MEETING AASHTO M180, CLASS A, TYPE I
(GALVANIZED). USE CLASS B W-BEAM TERMINAL. USE BOLTS, NUTS AND WASHERS (EXCEPT
BUTTONHEAD BOLTS) CONFORMING TO AASHTO M164 (ASTM A325 OR A449) AND GALVANIZED IN
ACCORDANCE WITH AASHTO M232 (ASTM A153). GALVANIZE CABLE ASSEMBLY IN ACCORDANCE
WITH AASHTO M30 (ASTM A741).
USE WESTERN WOOD (NO. 1 GRADE) TIMBERS CONFORMING TO THE CURRENT WWPA OR WCLIB
GRADING RULES FOR WESTERN LUMBER.
GALVANIZED STEEL W6X9 GUARDRAIL POSTS ARE AN ACCEPTABLE ALTERNATIVE TO TIMBER
POSTS SHOWN.
USE CONCRETE FOR END ANCHORS WITH A MINIMUM 28-DAY COMPRESSIVE STRENGTH OF 3000
PSI. USE WELDED WIRE FABRIC CONFORMING TO AASHTO M55 (ASTM A185).
FABRICATION: COMPLETE ALL LUMBER FABRICATION BEFORE TREATMENT. ALL STRUCTURAL
STEEL MUST BE SHOP FABRICATED. WELD IN ACCORDANCE WITH AWS STRUCTURAL WELDING
CODE D1.1. A CERTIFIED WELDER IS REQUIRED. FABRICATE ALL STEEL PRIOR TO GALVANIZING, EXCEPT MINOR SHOP CUTTING. DRILLING AND WELDING IS PERMITTED ON GALVANIZED METAL, PROVIDED THESE AREAS ARE CLEANED AND REPAIRED WITH 2 COATS OF ZINC DUST-ZINC OXIDE PAINT MEETING FEDERAL SPECIFICATION TT-P-641 OR MILITARY SPECIFICATION MIL-P-21035.
MAKE ALL RAIL SPLICES AT POSTS. SHOP BEND CURVED RAIL SECTIONS.
TREATMENT: AFTER FABRICATION, INCISE AND PRESSURE TREAT ALL TIMBER IN ACCORDANCE
WITH AWPA U1, USE CATEGORY UC4A. PROVIDE TREATMENT IN COMPLIANCE WITH THE
REQUIREMENTS OF THE CURRENT EDITION OF WWPA'S "BEST MANAGEMENT PRACTICES FOR THE
USE OF TREATED WOOD IN AQUATIC ENVIRONMENTS." PROVIDE A CERTIFICATE OF COMPLIANCE
UPON DELIVERY OF MATERIALS.
ERECTION: NO FIELD CUTTING OR WELDING IS PERMITTED ON GALVANIZED METAL UNLESS
APPROVED BY THE CONTRACTING OFFICER. SET ALL RAIL POSTS VERTICALLY AND ERECT THE
RAILING PARALLEL TO GRADE. FURNISH GALVANIZED STEEL SHIM PLATES AS REQUIRED TO
ALIGN RAILING. MAKE APPROACH GUARDRAIL POST HOLES A MINIMUM OF 18" IN DIAMETER,
UNLESS AUGERED OR DRIVEN. THOROUGHLY CLEAN THE BOTTOM OF EXCAVATED HOLES AND
COMPACT BACKFILL IN 4-INCH LIFTS. FILL ALL UNUSED HOLES IN W-BEAM WITH STANDARD
BUTTONHEAD BOLTS AND NUTS. AFTER ERECTION IS COMPLETE, BURR THREADS OF ALL RODS
AND BOLTS TO PREVENT BACKING OFF OF NUTS. REPAIR ALL DAMAGED GALVANIZED SURFACES
WITH 2 COATS OF ZINC PAINT AS SPECIFIED IN THE FABRICATION NOTE ABOVE. DO NOT USE
MORE THAN ONE RAIL SPLICE PER POST WHEN DOUBLE-LAYER W-BEAM GUARDRAIL ELEMENTS
ARE SPECIFIED.
REFLECTORS: INSTALL REFLECTORS (3"x4" (MIN.) WHITE, REFLECTIVE SURFACE) ON TRAFFIC
FACE OF EVERY OTHER APPROACH & TRANSITION RAIL POST.
