ADDITIVE ALTERNATE ITEM 1 - EQUIPMENT RENTAL <br />This item includes machine time using aturbo- charged excavator. Machine size will be a medium <br />sized, CAT 320BL or equivalent excavator with a minimum 20' reach and operator. Excavator time <br />is expected to perform bench recontouring and pull-back for slope alignments with surrounding <br />topography as well as site hydrologic control work, and other machine work as directed. Equipment <br />Rental will be in accordance to specifications (19.0) in the General Bid Specifications, 1996. <br />Equipment time will start as directed by the PROJECT MANAGER from the bench location. <br />Measurement and Payment <br />Payment for this task will be reflected under Additive Alternate Item 1 of the Bid Schedule as an <br />hourly rate for a CAT 3206E or equivalent excavator and operator. Bid hourly rate shall reflect the <br />CONTRACTORS estimate for equipment and personnel costs per hour to complete the task. <br />Measurement will be actual hours required to complete work as directed and approved by the <br />PROJECT MANAGER. <br />ADDITIVE ALTERNATE ITEM 2 - WEST SLOPE REVEGETATION <br />An approximate 0.5 acre area of downcast mixed soil and shaley material exists from a road cut <br />as shown in the field. The area is at an angle of repose (1.5:1). Forty (40) bales of mulch, <br />supplied by the OWNER, will first be distributed over the smaller area to be worked. Once an area <br />has had mulch evenly distributed, the surface will be manipulated by hand using a McLeod Fire <br />Rake, or equivalent as approved by the PROJECT MANAGER, to provide small seeding contour <br />furrows or benches. Furrows will be constructed so that the dimensions are no less than 12" in <br />width perpendicular to the slope with an 8" depth. Furrows will be spaced no further apart than 3' <br />center to center, horizontally (across the slope) and vertically (up and down the slope). The entire <br />approximate 0.5 acre area will be treated in smaller manageable sized areas to avoid the slope <br />fallout of the mulch to the bottom. The entire area will be treated with the mulch distribution and <br />mechanical surface procedure by hand. The result is to not only create furrows for seeding but <br />also to partially incorporate the mulch. Work will proceed at the top of the slope to bottom and from <br />side to side to minimize filling of the furrows by sloughing upslope material. After the initial <br />mulching and surface treatment has been performed, the entire area will be fertilized with BIOSOL <br />7.2.3 fertilizer that can be obtained from Rocky Mountain Bio-Products, Inc., Edwards, Colorado, <br />phone 970/926-1025. The fertilizer will be evenly applied at a rate of 1,500 pounds per acre (750 <br />pounds will be needed). After fertilizer application, seeding will be performed with seed supplied <br />by the OWNER. <br />Measurement and Payment <br />Payment for this item will be reflected in a lump sum bid under Additive Alternate 2 on the bid <br />schedule. This lump sum bid will cover payment of all costs for mulching, hand furrow construction, <br />fertilizing (including supplying BIOSOL fertilizer), and seeding. These revegetation procedures will <br />be performed on the delineated approximate 0.5 acre area as shown in the field. There will be no <br />measurement for payment. Payment shall be as this item is completed and approved by the <br />PROJECT MANAGER. Payment for this item will be made only for that amount shown under <br />Additive Alternate Item 2 of the Bid Schedule. Any or all incidental costs incurred by the <br />
