Bid Pricing - Fruita Mine Bond Revocation Project <br />Project Bid PKA-9-1149 <br />January 27, 2009 <br />The existing emergency spillway will be excavated to a depth of 3 feet below existing <br />elevation using a track excavator and front end loader (for transport of spoils). Upon <br />completion of excavation, aggregate materials consisting of 12 to 18-inch rip rap, <br />gathered from on-site sources will be placed at a depth of 3-feet, keyed in place each <br />20-feet of the channel. The rip rap will be extended approximately 4 feet up the sides of <br />the channel. The material removed from the excavation will be hauled and placed on <br />the southeast interior side of the pond bank, as noted on the bid drawing provided with <br />Amendment No. 1. <br />We will utilize a track excavator (John Deere 330 or equivalent), front end loader (John <br />Deere 744 with a 5.5 yard bucket, or equivalent), and hand labor to complete this task. <br />Task 3 - Rock Check Dams <br />P will install a series of rock check dams will be constructed along the access road, at <br />the portal bench, and along the fill outslope of the drainage channel. These areas are as <br />identified on the Site Overview Plan provided with the bid documents. The rock check <br />dams at the outslope and access road will consist of location and placement of 12 to 18- <br />inch diameter rip rap, and are as noted in Drawings 2 and 3 of Amendment No. 1. <br />To access the work areas with the proposed, we anticipate some road and access <br />improvements such as leveling of ground. As per project requirements, all disturbed <br />areas will be restored upon completion of the work scope. Except at the portal, rock <br />check dams will be placed, as needed and directed, every 20 feet in the stipulated <br />erosion areas. At the portal bench, check dams will be installed every 10 feet for <br />approximately 50 feet, and the rock consistency will be 60% 4-foot diameter, 20% 2 to 3- <br />foot diameter, and 20% 1 to 1.5-foot diameter rip rap boulders. Positive drainage will be <br />maintained with these check dams. <br />We will utilize a track excavator (John Deere 330 or equivalent), front end loader (John <br />Deere 744 with a 5.5 yard bucket, or equivalent), and hand labor to complete this task. <br />Task 4 - Drainage Repair and Construction <br />J3 will repair the gully that has been created by erosion from water draining at the mine <br />portal area to the pond at the bottom of the slope. A channel will be constructed 8-foot <br />wide, with side slope dimensions of 3H:1V. This channel will be approximately 250-feet <br />in length. The rip rap to be used will be collected from on-site sources and includes 20% <br />4-foot, 40% 2 to 3-foot, and 40% 12 to 18-inches in diameter. As a result of the larger <br />(4-foot diameter) rock, we will utilize a larger excavator than detailed in the RFP, and <br />front-end loader (5.5 yd. bucket). The excavated soils will be stockpiled as noted on the <br />RFP Drawing. These soils will be spread and evenly placed within the fill areas. Prior to <br />placement of fill, existing vegetation will be stripped and stockpiled at a depth of 24- <br />inches. <br />We will utilize a track excavator (John Deere 330 or equivalent), front end loader (John <br />Deere 744 with a 5.5 yard bucket, or equivalent), and hand labor to complete this task. <br />Pg. 2 of 5 www.j3env.com iQ
