A consulting engineering firm is preparing a pre- liminary cost estimate for adesign/construct proj- ect of a brackish groundwater desalting plant. The firm, which completed a similar project in 2001 with a construction cost of $30 million, wants to use the ENR construction cost index to update the cost. Estimate the cost of construction for a similar- size plant in mid-2006 when the index value was 7700.

Develop a programming budget estimate for a 100,000 square-foot warehouse, assuming a square-foot cost factor of $60 per square foot.  The site will be about 200,000 square feet with a site development cost of $3 per square foot. Use the following allowances to prepare your budget estimate: - Owner-furnished FFE: $1,000,000 - Owner soft costs: $800,000 - Programming fees: $50,000 - Geotechnical Investigation: $390,000

A landfill project requires 5000 m3 of compacted soil. The void index specified for the compacted landfill is 0.7. Three borrowing areas are available as indicated in Table 1, which relates the respective soil void rates and the cost per cubic meter of soil transport for the proposed construction site. Carry out the necessary calculations to select the borrowing area from which soil should be brought in to minimize costs. Assume Gs of 2.6 for all areas loan. Table 1 presents the data.
