The scope of work is for surface blading to maintain a native or aggregate road bed to facilitate traffic and provide proper drainage. This includes maintaining the crown, inslope or outslope of the traveled way, turnouts, and shoulders; repairing berms; blending approach road intersections; and cleaning bridge decks, drainage dips, and lead-off ditches. Surface blading is to be performed before, during, and after the contractor's use as needed. The surface blading must preserve the existing cross-section and eliminate irregularities to leave the surface in a free draining state. Water may be applied if sufficient moisture is not present. Oversized rocks on the traveled way must be removed and disposed of.
The related federal contract opportunity is Solicitation Number 127EAW24R0039 for Road Grading in the Upper Lake District of the Mendocino National Forest, with a total small business set-aside and an estimated magnitude between $25,000 - $100,000.

SPECIFICATION T-803 SURFACE BLADING
DESCRIPTION
1.1 Surface blading is keeping a native or aggregate Roadbed in a condition to facilitate traffic and provide proper drainage. It includes maintaining the crown, inslope or outslope of the Traveled Way, Turnouts, and Shoulder;
repairing Berms; blending approach road intersections; and cleaning bridge decks, Drainage Dips, and Lead-off Ditches.
REQUIREMENTS
3.1 Surface blading shall be performed before, during, and after Purchaser's use as often as necessary to facilitate traffic and proper drainage.
3.2 The surface blading shall preserve the existing cross section. Surface irregularities shall be eliminated and the surface left in a free draining state and to a smoothness needed to facilitate traffic. Surface material which has been displaced to the Shoulders or Turnouts shall be returned to the Traveled Way. The blading operation shall be conducted to prevent the loss of surface material and to provide for a thorough mixing of the material being worked.
3.3 Water, taken from Water Sources DESIGNATED ON THE SALE AREA MAP, shall be applied during blading if sufficient moisture is not present to cut, mix, or compact the surface material.
3.4 On native surfaced roads, Material generated from backslope sloughing and ditch cleaning may be blended with the surface material being worked. On aggregate surfaced roads this Material shall not be blended with Surface or Base Course material unless agreed otherwise.
3.5 Roadway backslopes or Berms shall not be undercut nor shall new Berms be established unless agreed otherwise.
Berms shall be repaired by placing Material as needed to restore the Berm to reasonably blend with existing line, grade, and cross section.
3.6 Drainage Dips and Lead-off Ditches shall be cleaned and maintained to reasonably blend with existing line, grade, and cross section.
3.7 Intersecting roads shall be bladed for a distance of 50 feet to assure proper blending of the two riding surfaces.
3.8 Rocks or other material remaining on the Traveled Way after the final pass that are larger than 4 inches in diameter or are larger than the maximum size of imported surfacing shall be removed from the Traveled Way. The oversized material shall be disposed of by sidecasting unless SHOWN OTHERWISE ON THE SALE AREA MAP. Sidecasting into streams, lakes or water courses will not be permitted.
3.9 Material resulting from work under this specification shall not remain on or in structures, such as Culverts, overside drains, cattleguards, ditches, Drainage Dips, and the like.
