See Maps & Road Spreadsheet for exact work dates and more information. All work shall be performed in accordance with standard industry practices for this type of work, and in accordance with the drawings & specifications of this contract. Existing conditions of Level 3 roads may be deteriorated and should be looked at individually to determine the level of work needed before bidding.

B. Pay Item 809(02) Water shall be obtained from a commercial source. Water may or may not be needed on all roads and will be used as a last resort if necessary. Use will be determined by the CO at the time of work.

C. Pay Item 860(01) covers all aspects of maintenance required by specifications 860 including surface & drainage maintenance, obstruction removal, vegetative clearing, and minor slough, slides, & slump removal.

D. Traffic Control shall be considered incidental to Pay Item 860(01).

E. Mobilization shall be considered incidental to Pay Item 860(01).

F. Final payment will be based on actual quantities in the field for all pay items.

G. When the work calls for routine blading (road grading) of forest roads, equipment operators with no pervious national forest road maintenance experience shall view a short (18-minute) video on proper road maintenance techniques prior to beginning work. The operator shall work in a manner that closely follow the techniques shown in the video.

1.2 Location of Project:

This project is located on the Pikes Peak Ranger District in the Pike National Forest. FR300 Rampart Range Rd is located east of Woodland Park and northwest of Colorado Springs. MP0.0 is located in Garden of the Gods in Colorado Springs. FR320 Mt. Herman Rd starts at the intersection of FR300 & ends west of Monument. The Monument Fire Center roads are located west of Monument. Refer to the Maps & Road Spreadsheet for a detailed location of each road. All roads are located in El Paso County.

All berms generated shall be removed from the shoulders and incorporated into the traveled way surface except those that are specifically designated to remain. Turnouts shall also be included with the blading of the road surface.

On roads open to public traffic, berms of materials caused by road maintenance operations shall be removed from the traveled way prior to the end of each day's work.

The blading shall proceed in an orderly fashion by successive passes with graders parallel to the road centerline, progressing from the lower side to the upper side of the roadbed and back across. In the process, shoulder material shall be cut and replaced to prevent vegetation encroachment.

On native surface roads, all ruts, holes, washes and washboards shall be removed by scarifying or cutting to the bottom of such defects. Fines accumulated in blading roads or from drainage ditches shall not be wasted over fill shoulders.

Sidecasting into streams, lakes or water courses will not be permitted.

The roadbed immediately before and after cattleguards and bridges shall be bladed in such a manner as to effect a smooth transition. Material shall not be deposited inside cattleguards or onto bridges. Any material deposited on bridge decks or inside cattleguards, including any accumulated material, shall be removed.

Intersecting roads shall be bladed for a distance of 50 feet to assure proper transition of the two riding surfaces.

MEASUREMENT
