1 Project Estimate Summary Project Cost Evaluation Table 4 shows the Construction Cost, CC/SF, Total Cost, TC/SF, the Building Systems Cost, and Building Systems Cost/SF based on the budget for. Table 4 Project Cost Evaluation Data Construction Cost $3,608,099 CC/SF $47.13 Total Cost $5,326,003 TC/SF $69.56 System Costs Plumbing System $344,303 Cost/SF $4.50 Fire Protection System $111,018 Cost/SF $1.45 HVAC System $391,319 Cost/SF $5.11 Electrical System $590,399 Cost/SF $7.71 Elevator $52,500 Cost/SF $0.69 Structural System $998,343 Cost/SF $13.04 The actual cost for is $5,326,004. The cost determined using D4 Cost Estimator is $6,608,366, the D4 cost summary can be found in Appendix III. A comparison of the actually cost verses the D4 costs for each division is shown in Table 4. The likely reason D4 estimated a cost much high then the actual cost is that D4 did not take into consideration the type of structural system. The structural system in is wood frame. Comparing the costs for division 5 shows, that D4 has estimated $709,402 over the actual. Mostly likely D4 is assuming the structural system to be steel. This large difference adds to the inaccuracy of the D4 Estimate. PAGE 18

Many of the member sizes used on do not match the member sizes called out in R.S. Means. The estimates are to the best closest member. Table 5 is the estimate for structural wood system in project; from this estimate, it is predicted that the structural wood system will cost $93,923. The quantity take-offs for this estimate can be found in the appendix at the end of this report. PAGE 19

The foundation system is slab on grade with cast-in-place square footings. The superstructure consists of mostly timber columns and a few steel columns, timber floor and roof Warren trusses, and some timber and steel beams generally in the corridors near the stairwells and elevator shafts. The few steel members used in the building are in areas where the dead loads are greater then typical dead loads in the rest of the building. The following is a cost summary for the structural system organized in the CSI Masterformat, the detailed cost estimate and take-offs can be found in the Appendix. The total cost for the entire structural system is $390,928. PAGE 22
