Margaret Lane <br />P.O. Box 8181 <br />Hillsborough, North Carolina 27278 <br />Re: Proposal for: <br />Additional Geotechnical Investigations (311 Revision) <br />Hillsborough Area EDD Ph 1 Water & Sewer Extensions <br />ORA -17000 <br />Dear Mr. Sandt: <br />Attachment B <br />"Additional <br />Geotechnical <br />Investigations" <br />In response to our discussions regarding the need for additional geotechnical <br />investigations for the Hillsborough Area Economic Development District — <br />Phase 1 Water and Sewer Extensions project, McAdams Company offers this <br />proposal for additional professional services. <br />PROPOSED SERVICES AND FEES <br />We propose the services described below. McAdams' sub - consultant, Falcon <br />Engineering, Inc., will perform this work under contract with McAdams. A <br />table summarizing the fees follows the task descriptions: <br />THREE (3) BORINGS AT NEW TUNNEL LOCATION <br />• This task is for the drilling of three (3) borings along the proposed new tunnel <br />alignment for the subject project. <br />• The three (3) borings would be advanced near the beginning, end, and middle <br />(I -40 median) of the tunnel. The borings within the I -40 median will require <br />traffic control services consisting of a shoulder closure. We anticipate the <br />shoulder closure will occur under the terms of our prior encroachment <br />agreement, between the hours of 9AM and 4PM. A single day of traffic <br />control is included in this proposal. If our boring cannot be completed in a <br />single day, will contact you to discuss the most appropriate course of action. <br />• All borings will be located in the field by Falcon personnel using handheld <br />GPS equipment and approximate coordinates correlated from GIS data. <br />Approximate boring elevations will be estimated from the County GIS online <br />topographic data, or site topographic data provided by others if available at <br />the time of our report. Falcon will contact the North Carolina One -call Center <br />(NCOCC) to request subscriber utilities be located on site following staking <br />McAdamsCo.com Designing Tomorrow's infrastructure & Communities <br />
