Biscayne Construction Company = $13,000 plus equipment ownership received. . Jennings Towing = $11,500 less $1,500 for prompt payment And City equipment iise 3. RCS Salvers = $ 9,800 Due to the uniqueness of this task, it is necessary that I make some comments on the proposed methods to be used in this retrieval. Firstly, however, no consideration should be given to bidder rl above since (a) costs are excessive and (b) no viable plan stated. Hence, it becomes a matter of choosing either bidder 42 or bidder #3 since there appears to be only a $200 difference in charges. Analysis of Bidder #2 Plan: This bidder states that he will pump water (assumable from the bay) into the "sink hole" for four (4) days in an effort to break up the solids and allow a diver easy entry into the water to hook up pull cables. The problem I foresee with this method is an overfilling of the existing pond area thereby enlarging it, softening the ground around the pond and thereby creating an inability of the surrounding ground to support other heavy equipment required for the retrieval. Assuming the surrounding ground and sub strata have the absorption capabilities to prevent present pond overflow, the introduction of thousands of gallons of water over a four -day period will have a tendency to undermine the surrounding ground area, thereby creating an unstable condition on the surface which will also not support needed heavy pieces of equipment for retrieval. (NOTE: Without a soils study there is no way to know if speculative conditions will occur.) It is also note worthy that the original contractor attempted to introduce pumped bay water and abandoned that program for reasons unknown. *dote: $500 for prompt payment and $1,000 for use of City equipment, This bidder also iftdioates that he wishes to use the eity+s bulldozers as "anchors" during the actual pulling phase, i would point out that we are on out '`last legs" bulldozer wise and are presently renting a bulldozer to suppleMeht our own equipttient Which constantly breaks down We May be tisking severe damage to our equipment if we subject it to unnecessary stress. (NOTE: The practice of using such equipment as an "anchor" is an acceptable one, however, when no other readily available fixed object can be found.) Analysis of Bidder *3Plan: This bidder incorporates two plans, noting that if his Plan 1 fails, his Plan 2 will be used as an alternative. To reduce the Viscosity of the sludge, this bidder proposes to introduce air into the pit and break up the sludge. The sludge would then be pumped into an adjacent area. NOTE: The original contractor attempted to pump this sludge; but due to much foreign debris in the pit, his pump became clogged. The aeration process nay float this debris to the surface where it can be cleared away from suction hoses, and there- fore not clog the pump. When the liquid sludge is cleared, lines will be attached to the equipment and it will be pulled out by mobile power winches. Their Plan 2 indicates that in the event pumps cannot reduce the water level, the pit area will be filled with sand/gravel and then this mixture removed by backhoe. This area which was formerly known as Duck Lake has been filled over the years with rubbish and fill; and apparently, the water has either "pocketed" elsewhere or been absorbed. In essence, both bidders have the same basic thought; i.e., reduce the viscosity of the sludge, so that either a man can enter the water and hook cables or lower the water level and then hook cables. In evaluating the methods described, several other factors should be considered. Will the methods: 1. Endanger human life? 2. Damage the equipment beyond retrieval value? Make conditions worse and therefore preclude, any further attempts at retrieval? — th' a: previous MeMorandUM to you which oovered in part this retrieval. 1 ekpressed my desire to oversee this pro5eet sides I.believe the work requires a City employee with some expertise in this area to superVise a Althottgh I aft hOt an expert in suoh salvage operations► 1 do believe that soytle significant ekperiehces I'Ve had in such matters can be of benefit in assuring that methods Used and work approach are of a professional level. t will endeavor to work closely with the contractor and as stated personally super - Vise the activity. Accordingly; and in View of the fact that Jennings Towing Service has had some experience with retrievals of this nature and despite the speculative drawbacks of his plan as I've noted, I recommend that the award for this work be given to them. Jennings as indi- cated to me that the $500 discount offered in his bid applies if he receives payment for retrieval within 15 days after completion. He has also indicated that 14 calendar days is what he requires to perform the task. BID SECURITY FEM `et ieVe...SUbMet ed._ BUi1ddzer and Truck ai-.
