III Mobil ization/demobilization shall not exceed 20%of the total bid price. IV TBD=to be determined.This item is optional and may or may not be required.This item involves potential dewatering/pumping of liquids that may have been accumulated,due to recent rainfall events,within the southern portion of Cell 1(i.e.,area of Cell 1 south of the east-west rain flap)as shown on the Construction Drawings. Liquids shall be pumped to a tanker truck and transported to the Bio-solids facility for disposal which is approximately 3,300 ft(0.62 miles)one-way from the rain flap location. Contractor shall provide unit cost for a tanker truck to pump and transport liquids to the Bio-solids facility,which is located at the landfill facility. The tanker truck should have the capability to pump the liquids into the truck. However,the landfill operator has two pumps(one 3-in. pump and one 6-in.pump that could be used if necessary. V Contractor shall provide equipment and labor for the removal of rain flap as shown on the Construction Drawings. Equipment used shall be approved by the Engineer prior to being used. The sand along the rain flap shall be carefully removed to expose the tie-in point between the flap and the cell liner. The flap shall be cut away from the cell liner carefully to avoid any puncturing of the liner system. Upon flap removal,the geocomposite that had been bent up behind the flap shall be folded down flat onto the liner against the existing geocomposite termination point. In order to patch the geocomposite back together prior to reinstalling the sand cover, place a cap strip of geotextile(8-oz/sy minimum)or approved equivalent over the seam and sew it into position. The Contractor shall ensure that no sand will infiltrate the geocomposite in the area of the patch. The Contractor shall also provide the required geotextile material.Any excess sand from the rain flap/berm shall be sporead and graded into the as-constructed liner protective layer of the southern portion of Cell 1. This item also includes the connection of the leachate collection line as shown in the Construction Drawings.This shall be accomplished by cutting and cleaning both ends of the pipe at the liner flap location;providing a spool piece(approximately 7 ft long) of 6-in.dia.SDR I I HDPE pipe and two electro fusion couplers;and connecting the pipe together. The Contractor shall provide geotextile material to connect the leachate collection"burrito wrap"and shall place the leachate collection gravel around the pipe in the burrito prior to sewing the geotextile overlap. The Owner will provide the gravel needed to the tie-in location but the Contractor shall be responsible for placing the geotextile-gravel burrito as shown on the Construction Drawings. The Engineer has estimated three days for this work;Contractor shall indicate the number of days required for this work. VI This item includes the following materials needed for the project:(i)6-in.dia.SDR 1 I HDPE spool pieces;(ii)two 6-in.dia.electro fusion couplers;and(iii)8-oz/sy nonwoven geotextile required for the geocomposite tie-in point cap strip and for tying the leachate collection system gravel burrito together. The Owner will provide the gravel required to complete the burrito wrap.Approximately 3.6 cy of gravel will be required to constructed the pipe-gravel burrito in this section;this gravel should be obtained from the rain flap berm along the leachate corridor plus a small stockpile on site. VII The Contractor shall provide this leachate pump(see attached Cut Sheet)which will be used as a back-up pump for Cell 1.This is a submersible pump for leachate collection in the side slope riser of Cell 1. This item is optional and the Owner may elect to have this purchased as part of this contract. *Pricing reflects solid pipe for tie-in. If perforated pipe is desired, add $50 to the total shown. %aw Note: Pricing for item #2 is for one week (5 days) utilizing 6,000 gallon truck and is contingent upon gravity discharge of the leachate at the onsite treatment facility. Assumes 5 loads per 8 hour work day. COMANCO proposes to subcontract the onsite leachate hauling to Accurate Septic Services, Inc. (4120 Selvitz Road, Fort Pierce, Florida 34981) . Pricing for item #5 is for a standard Sligo submersible pump (SSR Series 1 PSF) . COMANCO proposes to use an 80 size excavator, as well as other small company-owned equipment to complete the work. 190
