I. COST ESTIMATE ■ APACHE PLAZA COST ESTIMATE OVERVIEW The following cost estimate pertains to demolition of the existing Apache Plaza Mall structure, and ■ preparing the site for future development. Demolition Costs within the demolition price are based on a walk through by HGA on December 12, 2000. The walk through included Jim Monk, the on-site facilities engineer, HGA's Architect, Cost Estimator, Structural, Mechanical, Electrical, and Civil engineers. (See specific narratives by each discipline within this report for further information.) The quantities used to price this study have been defined ■ within each specific narrative. For the most part, drawings for Apache Plaza were not available so the information collected during the walk through accounted for the majority of the knowledge on ■ which this estimate is based. Two distinct areas, structural steel construction and concrete construction, comprise the major building demolition. Scrap for demolished metal material clearly shows a rebate for the project. The cost of the rebate will fluctuate depending upon how the market fares at the time this work would be put out for bids. Foundation demolition was defined separately from the building demolition as described in the estimate. . Asbestos Abatement . Wenck Associates, Inc. has supplied all costs included for this section. HGA has included from the cost study from Wenck, the cost for removing all friable and non-friable asbestos material prior to ■ demolition. It should be noted that within this section, the cost to remove asbestos floor tile prior to demolition might not be required based on current demolition practices. City and government agencies will need to be contacted for further information to clarify if the tile can remain during the demolition process. This estimate includes a cost of$845,000 to remove the floor tile prior to demolition. Noted also in the cost study are other hazardous material costs that are included as ■ described in the Wenck document. See Wenck document for further clarifications. Clearing of Site Asphalt paving around the existing building has been figured to be totally removed from the property. Excavation, Grading & Backfill After all debris has been removed the basement volume will need to be filled in to bring the site to a level condition. Borrow material will have to be hauled to the site from a borrow pit to complete this . operation. Rough grading will take place in conjunction with the filling of the basement area to establish consistent grade elevations. ■ Site Drainage & Utilities Removal of existing utilities and the relocation of storm, sanitary and water along the east side of Silver Lake Center are included in the costs for this estimate. The civil/site description clearly defines the lines that could stay during demolition but highly recommends that they be moved. Cost ■ saving could be achieved for the storm and sanitary if they aren't relocated. Roads and Walks • Costs in conjunction with the relocation of the storm,water, and sewer as described above include . the repair of existing paving and curbs as described in this section. 2 .
