To estimate the budget, we need to consider the scope of work and materials involved. The project involves saw cutting, removal of existing asphalt, demolition of flowable fill, and installation of new stone subbase and asphalt. The quantities are specified as 975 linear feet of saw cutting, 3,900 square feet of asphalt binder, and 3,900 square feet of asphalt top course. Without specific unit prices, it's challenging to provide an exact estimate. However, considering the average costs for such construction projects, a rough estimate could be made. For example, the cost of asphalt paving can range from $2 to $5 per square foot for binder and top courses, and stone subbase costs can vary widely depending on location and quality. Assuming an average cost of $3.50 per square foot for the asphalt work and considering other costs like labor, equipment, and materials for subbase and demolition, a total project cost could be estimated. Given the quantities, a very rough estimate for the asphalt work alone could be around $13,725 to $19,500 (3,900 sf * $3.50/sf to $5/sf). Adding costs for subbase, demolition, and other aspects, the total project cost could easily exceed $50,000 to $100,000 or more, depending on the specifics of the site and the contractor's bids.
