Mr. Savage has offered a number of useful comments, which suggest the reason for <br /> these high bids. I call your attention to several factors he has cited, which are relevant <br /> to the bids received: <br /> In General: <br /> • The lack of detail and specificity in the preparation of the bidding documents, <br /> even though much of this information is available in the permit and revision <br /> documents, will likely result in bids to complete the specified tasks being higher <br /> than needed, since lack of specificity causes contractors to "hedge their bets" <br /> and bid very conservatively. <br /> • Additional bid items which do not correlate to specific reclamation tasks as <br /> identified in the bids. <br /> • Seeding rates are excessive. <br /> Sutey101d Refuse Pile <br /> • Overdesign of the surface drainage, reconstruction of in-place ditches and <br /> overly zealous use of expensive and unnecessary liners and netting. <br /> • Use of silt fence (2,000'-2,800') is expensive, and of questionable benefit. <br /> • Extent and location of grading is unclear, of concern is whether CDMG <br /> proposes to regrade areas that have had ditches previously installed and/or <br /> been topsoiled and revegetated. <br /> • Seeding rates are excessive (2X and 20X the rate recommended); this high <br /> rate wastes seed and will probably lead to increased seedling failure. <br /> Mine #3 <br /> • Alternatives to silt fencing should be considered. <br /> • The quantity of backfill material is not specified.' <br /> In April, 1994 Greg Lewicki, P.E., submitted reclamation plans for the benches at Mines#3 and#4. <br /> The existing sites were modeled in 3 dimensions using Eagle Point civil engineering software working <br /> inside AutoCAD. Cut and fill plans were developed, with plan view maps and cross-sections delineating <br /> the partial reclamation of these benches. Volumes were calculated for the cut and fill earthwork. All <br /> demonstrations were made to meet the new highwall reclamation requirements, including a detailed <br /> slope stability analysis using material sampled from each of the portal benches. In June, Mr. Renner <br /> requested additional cross-sections for both portal areas. These were completed and submitted on June <br /> 26, 1994. It should be noted that because the construction of the bench areas occured decades ago, <br /> there is no certainty as to the amount of reasonably available material which can be recovered. <br /> However, it is suggested that use these studies would provide greater specificity for bidders. <br /> 2 <br />
