Title
Consultant Services Amendment - Old Landfill at Sweetwater Branch (B)
Explanation
Since 2002, consultants and staff have been working with the Florida Department of Environmental Protection (FDEP) on developing a plan to provide proper cover on the bank of a closed landfill that adjoins Sweetwater Branch. Between then and now, the consultant - Golder and Associates - has completed numerous tasks beyond the original scope of work. In October 2002, the City Commission authorized an additional $78,201 for tasks related to the emergency work required due the culvert failure in Sweetwater Branch under the road leading to the old Compost Plant site.
Since then Golder and staff have developed and received approval of a concept plan for stabilizing the banks of concern and prepared the bid documents necessary to implement the approved plan. Golder's work during development of the concept and final plans and specifications required additional skills beyond those originally estimated when developing their contract and scope of work. Structural engineering and special bank stabilization measures were required due to the necessity to keep all waste materials on site. Waste materials, if excavated, have to be taken to a suitable landfill. Earlier work on the site identified some hazardous materials on the site that were disposed of for a cost of $220.00/ton. To avoid removal of old landfill material, the decision was made to use sheet piling and rock filled baskets to provide separation between the creek and the Old Landfill. Additional oversight and inspection costs are expected due to a longer construction schedule than originally envisioned. Costs for these tasks are $56,190 and $53,996, respectively, totaling $110,186. However, because of economies realized in the variety of task budgets during the previous work, only $77,624 additional compensation is needed for Golder's work.
