Ivy Tower Phase II February 27, 2012 Page 5 of 7 SCHEDULE Wightman Petrie proposes to commence site investigation activities within one (1) week of receipt of notification to proceed, depending on weather, utility clearance and Geoprobe availability. Our Ground Penetrating Radar Survey work will be completed prior to the initiation of and soil boring installation activity, and can commence immediately following the receipt of Authorization to Proceed. Once a specific date for the field component of the Phase II has been established, Wightman Petrie will notify the client. Upon mobilization, we anticipate completion of the Geoprobe sampling requiring two (2) days. Laboratory analyses will be completed by Pace Analytical on standard one -week turnaround from receipt by the laboratory. Our initial discussion of results will occur within one (1) day of receipt of laboratory analytical results. Our written "Summary Letter Report" will be submitted within one (1) week of the initial conference. COST ESTIMATE An ESTIMATED COST for Phase II Environmental Assessment Services is presented as follows: Field Engineering Services /Project Management $2,000 Limited Ground Penetrating Radar Survey $ 900 Geoprobe Rental (assumes 2 -days $1,700 /day, including mobilization) $3,400 Laboratory Analysis: 14 soil samples for % Moisture @ $10 /sample $ 140 14 soil samples for analysis of VOC constituents @ $95 /sample $1,330 14 soil samples for analysis of carcinogenic PAHs @ $95 /sample $1,330 11 groundwater samples for analysis of VOC constituents @ $95 /sample $1,045 7 groundwater samples for analysis of carcinogenic PAHs @ $95 /sample $ 665 TerraCore Soil Sampling Kits (36 kits @$15 /kit) $ 540 Reporting $1,250 ESTIMATED COST $12,600 Please note that this ESTIMATED COST should be considered a Project Maximum, which Wightman Petrie will not exceed without prior approval. However, should the scope of services require modification (i.e., additional borings) based upon field conditions and /or circumstances that would not have otherwise been anticipated, Wightman Petrie will notify the client of such "changed conditions" and resultant cost implications to the project. LIMITATIONS /QUALIFICATIONS The sampling and testing of soil, groundwater and /or other materials not specifically identified in this proposal is beyond the scope of services for this project. Cost estimates for our proposed services have been prepared based on the following assumptions: • Wightman Petrie will have unlimited access to the site during daylight hours; • No subsurface obstructions (buried utilities or fill debris) will interfere with our work; • Sufficient access /clearance will be provided for exterior Geoprobe locations; • Groundwater will be encountered within 25 -feet of ground surface; • Inclement weather will not interfere with the completion of our field work; • Soil cuttings and purge waters will be returned to the boring from which they were generated, with the remainder of the boring filled with bentonite pellets to land surface. This Phase II Environmental Site Assessment should be considered as a "tool' in the evaluation of the subject site relative to the potential presence of contaminants, and does not necessarily fulfill Indiana Department of Environmental Management (IDEM) guidelines for delineation of contaminants identified within soil or groundwater as required under UST Closure Guidelines.
