Louisville Housing Authority January 21, 2004 differences in the site work and the structures, we have neglected those differences for simplicity. Summary Spreadsheet We have prepared a side by side summary spreadsheet of the per -unit costs for the 4 -unit and 6 -unit projects. That summary sheet is attached for you reference. Overall, not including the contingency fund, the per unit cost drops from $164,500 for the 4 -unit to $139,400 for the 6 -unit. We project that the 6 -unit project will have approximately $13,500 in additional site costs over the 4- unit, due principally to the retaining walls necessary around the patios and the trash enclosure. This additional site work cost for the 6 -unit amounts to about $2250 per unit, but the increase in the number of units drops the overall site work per unit cost by a net $8125. The $16,975 remainder of the per -unit cost reduction is due to the smaller units (1200 Sq. Ft.) necessary to get the 6 -unit project on the site comfortably. 4. Cost Reductions We have reviewed the costs associated with the site work as submitted to you on January 19, 2004. There are two specific opportunities for budget cost savings Contingency - This is a budget number that is used to cover unknown or unanticipated items at the early stages of cost projecting, and a construction contingency for unforeseen conditions and variations in bid prices. We would not like to see that number ever reached in actual expenditures. It is not prudent however to enter into a project like this without this kind of fund unless we have a great deal of detail and a contractor on board pricing hard numbers for the project. The further the project goes into detail design the greater the certainty on the quantities and the unknowns become fewer. At that point, the contingency budget can be reduced. The contingency budget should be viewed as a worst -case scenario, and not as the budget target. Drainage wall — The need for and the extent of the drainage wall along Ridgeview and South Boulder Road will be reviewed in much more detail as the engineering. The cost for this wall was included as a line item to cover a worst -case problem for the initial budgeting. I do not expect that the entire wall will need to be constructed as shown, but we expect that some portion of that line item will be needed for drainage resolution. Further engineering will define that need more accurately. 5. Water and Sewer Tap Fees Pending resolution 6. Field Utility Locates Marked - Pending location 7. Comcast Cable Pending resolution We will be available to answer questions on call. Attached are two reduced size site plan sketches, a 4- unit and a 6 -unit plan, and a cost spreadsheet comparing the two. Page 2
