Maps <br /> Attached to this Invitation to Bid are copies of Maps 4 and 5 reproduced on legal size paper. <br /> Due to the cost of reproducing full size maps, the reduced size maps are included for your <br /> reference. Full size maps (approximately 24" x 30") will be provided to those contractors who <br /> attend the pre-bid meeting scheduled for 20 June, 2000 at 10:30 a.m. See Map 2, Pre-Bid <br /> Meeting Location. <br /> Map 4, Hydrologic Structures, depicts the roads to be reclaimed and pertinent hydrologic <br /> structures, including existing culvert locations, locations of low water crossings to be <br /> constructed and locations of rolled dips to be constructed. <br /> Map 5, Earth Work, depicts the roads to be reclaimed and the locations where cross sections <br /> were measured, areas to be ripped and not ripped, areas to be backfilled to 0% slope and areas <br /> to be backfilled to 1% slope. <br /> TASK 1 MOBILIZATION AND DEMOBILIZATION <br /> This Task shall comply with Specification 1.0, Mobilization / Demobilization, of the Colorado <br /> Inactive Mine Reclamation Program General Bid Specifications, 1996. <br /> Site Clean Up <br /> Miscellaneous metallic and non-metallic debris may be encountered throughout the Project <br /> Area. This material will be removed from the site by CONTRACTOR. Pipe, scrap metal, steel, <br /> road guard rail remnants and miscellaneous debris, primarily situated on the ground surface, <br /> may be present. Plastic, metallic and similar materials, when encountered, must be removed <br /> from the site by CONTRACTOR. Wood materials may be cut into small pieces (not to exceed <br /> twenty four inches [24"] in length and eight inches [8"] in diameter), and distributed on the <br /> revegetated road surfaces in a random pattern. All non-wood debris and scrap materials <br /> encountered within the Project Area must be properly disposed of. Disposal may occur at an <br /> appropriately licensed land fill, or CONTRACTOR may salvage such materials. <br /> Measurement and Payment <br /> There will be no measurement for payment.

Map 4, Hydrologic Structures, depicts the locations of the <br /> culverts to be removed. <br /> Generally, road drainage culverts are buried by three feet (3') or less of ground cover at the <br /> inlet. These culverts are constructed of corrugated metal pipe (CMP) in almost all instances. <br /> The culverts listed in the following table shall be decommissioned as part of the reclamation <br /> process. Any head walls, down drains or other structures associated with the culverts shall be <br /> removed during reclamation. The entire culvert will be excavated and removed. The trenches <br /> 8 <br />
