.n Leighton Consulting ( (Ab) Environmental Services !,« law ?y 2E I COST AND PRICE PROPOSAL Phase I and Phase II ESAs come in all shapes and sizes. Sites range from single parcel lots to corridors spanning many miles. For the purposes of this proposal, we have assumed a one-acre, single Assessors Parcel Number (APN) which requires a Phase I ESA, followed by a Phase II ESA. cam, Based upon the Labor Allocation Table included earlier in this document, we assumed a baseline Phase I ESA would require approximately 25.5 hours to complete. Using the labor rates included in Exhibit B, this would result in approximately $3,100 In labor charges. Adding $500 for the -tic, database search report (EDR or similar), a baseline Phase I ESA would cost $3,600. .:, For the Phase II ESA, We assumed a geophysical survey would be performed to clear boreholes and identify subsurface anomalies followed by a soil (direct-push) investigation on the first field day (after mark-out) The second field day would consist of a soil vapor investigation with onsite mobile laboratory. Using the Labor Allocation Table for the "typical" Phase 11 ESA and the labor rates in Exhibit B, this "typical" Phase 11 ESA would cost $24,594, based upon the following d. breakdown: • Geophysical Survey - $2,000 • Two days of direct-push rig - $5,200 • One day of Mobile laboratory- $2,700 Leighton labor - $14,594 We assumed one 3,000-square4oot structure is located on the property, requiring assessment for hazardous materials, namely asbestos and lead-based point. The hazardous materials survey for this building would cost approximately $2,400. This amount could vary slightly, depending on the age of the building and construction materials.
