TRRFPER MINING INC TEL~303-824-4632 Jan 04 96 13 37 No.005 P.10 <br />changed from o.70 to 1.10. The net job correction factor for road <br />reclamation will be 0.65. <br />Replacement oP Topsoil <br />Both Trapper Inc. and the Division agreed that the equipment <br />selection of scrapers would also be incorporated into the survey, <br />as well as the shift selection. When asked the question regarding <br />equipment to be used on site, not one contractor chose a 657 <br />scraper. Ali of the contractors stated that a 631 or 651 scraper <br />would be ideal for the project. None of the contractors opted to <br />use the 657 Scraper because of the down time in between projects. <br />Based on this information, the Division feels that a 637 Scraper is <br />more appropriate to be used in the estimate. According to the <br />contractors they are more accessible than the larger models. They <br />can also be used in smaller projects, which results in less down <br />time. Shift selection was also addressed, and the responses ware <br />similar to the shifts chosen for dozer work. All of the <br />contractors stated they would work on a single shift basis if there <br />is no production quota. Based on this information, the Division <br />Peels that single shifts for topsoil laydown is appropriate for the <br />bond estimate. <br />Revegetation <br />The Division has researched the question posed by Trapper Tnc. <br />regarding profits included in the revegetation cost. Profits were <br />found to be included in some of the application method quotes. <br />Such profits are included in diecing, seed application, fertilizing <br />application and mulch application method. Trapper may reflect the <br />cost of profits accordingly in the bond estimate. <br />This concludes the Division's additional information and comments <br />reached on November 17, 1992. Please do not hesitate to contact me <br />if you have any questions regarding this memo. <br />Sincerely, <br />Erica S.
