Van Milligen MCVM/jh Attachment cc: Barry Lindahl, Corporation Counsel Cindy Steinhauser, Assistant City Manager Michael A. Koch, Public Works Director CITY OF DUBUQUE, IOWA MEMORANDUM TO: FROM: SUBJECT: June 8, 2001 Michael C. Van Milligen, City Manager Michael A. Koch, Public Works Director Fischer Cold Storage Warehouse and Carriage Building Demolition and Site Clearance Project INTRODUCTION The enclosed resolutions provide for the acceptance of the demolition contract for the Fischer Cold Storage Warehouse and Carriage Building Demolition and Site Clearance Project. BACKGROUND On October 18, 2000, the City completed the Plastics Center, Inc. property acquisition which included the former Fischer Cold Storage Warehouse and Carriage building. Pursuant to the Development Agreement with Platinum Hospitality Group, Inc., the City was required to complete the demolition of existing structures and provide environmental site clearance prior to finalizing the property lease agreement. DISCUSSION The Fischer Cold Storage Warehouse and Carriage Building Demolition and Site Clearance Project has been completed by Peterson Contractors Inc. of Reinbeck, Iowa, in the final contract amount of $180,725.00, which is an 8.8% increase from the original contract in the amount of $166,100.00. The City incurred all landfill solid waste disposal costs and all hazardous matedal mitigation cost associated with the project, the total project cost was $358,725, which is a 3.8% reduction from the estimated cost of $373,000. The demolition and site clearance project included the complete demolition of existing structures, which included the excavation of building foundations and the removal, cleanup and disposal of all building materials from the former Plastics Center, Inc. property. The project also included the disconnection and abandonment of both City and public utilities to the Cold Storage Warehouse and Carriage Building. The reason for the increase in demolition contract cost resulted from unexpected subsurface structures encountered during the demolition operations. Upon excavating the subsurface foundation walls and footings, the contractor uncovered four (4) large concrete substructure foundations. The uncovered concrete substructures were approximately 6 feet below grade and were in the size range of 20' by 20' square and approximately 30' deep. Due to the unforeseen condition, the quantity and massive size of the concrete substructure foundations, the City agreed to a change order to excavate, demolish and disposal of the large concrete foundations on a time and material basis. The additional cost to excavate, demolish and dispose of all concrete substructure foundations was $18,995. A significant cost component of the demolition and site clearance project was the landfill solid waste disposal costs. To eliminate the contractors cost, profit plus an unknown contingency factor to cover landfill disposal charges, the City directly incurred all demolition disposal costs associated with the project. The former Plastics Center, Inc. cold storage warehouse was constructed with concrete, brick, masonry block, internal steel columns, beams and trusses with either cork or foam insulation incorporated into the interior and exterior walls, roofing materials and concrete floor slabs. A substantial portion of the exterior bdck or masonry block walls had a spray-on foam insulation which was attached to the exterior walls. Based upon both DNR and Federal solid waste landfill regulations, all loose foam, cork, insulation or materials with foam, cork, insulation attached which can not be separated, such as concrete, masonry block or brick, all timber and wood building materials, roofing materials and railroad ties, are classified as solid waste and are required to be disposed at a permitted landfill. To comply with DNR and Federal regulations and reduce the potential liability of the City, the contractor was required to dispose of all solid waste demolition materials at the Dubuque Solid Waste Landfill. The final project cost to dispose of all solid waste demolition materials at the landfill was $140,862. ASSOCIATED PROJECT COSTS Asbestos Abatement: Prior to starting the Warehouse and Carriage building demolition, all asbestos containing building materials was removed from the property. The asbestos abatement work was completed by Advanced Technologies Corporation of Cedar Falls, Iowa in the final amount of $3,200. Hazardous Material Mitigation: Upon inspecting the former Plastics Center, Inc. property, staff discovered twelve (12) electrical transformers and twelve (12) oil switching units. The City hired Alliant/Interstate Power to inspect the property and sample all electrical transformers and oil switching units. The samples were sent to a testing facility to determine if any equipment contain hazardous materials (PCB's), The results of the tests indicated that of the twenty-four (24) samples, only one (1) tested positive for PCB's levels above the allowable threshold. The City negotiated with Peterson Contractors to dispose of the one (1) PCB contaminated transformer for the copper salvage value of the remaining eleven (11) non-PCB contaminated transformers. Thus, no additional costs were incurred to remove and dispose of the electrical transformers and oil switching units. The final cost for Alliant/Interstate Power services and the associated lab PCB testing fees was $2,510. Artesian Well Abandonment: During demolition operations, two (2) deep artesian wells were uncovered under the eastedy loading dock. Peerless Service Co. of Dubuque was responsible for maintaining the wells for the former Plastics Center, Inc. property and had documented history records. The City hired Peedess Services to abandon, fill and cap the wells, in compliance with DNR well abandonment regulations. The cost to abandon the two artesian wells was $5,250. Underground Storage Tank Removal: During demolition operations, three (3) underground fuel storage tanks were discovered. Two (2) tanks were located next to the former site of the Carriage Building and the third tank was located next to the former Burlington Northern Railroad Depot Building. The City retained Preston Engineering, Inc. to consult on the tank removal and provide on-site inspection, monitoring and sampling during the tank removal operations. The City hired a specialized contractor to uncovering the tanks; remove all residual liquid from the tanks; excavating and removing the tanks from the ground; cleaning and disposing of the tanks. The final cost to remove the underground fuel storage tanks was $6,150. RECOMMENDATION I would recommend that the City Council accept the improvement and recommend that the final contract amount be established at $180,725.00.
