 January 4, 2016 Mr. Heath Jenkins, PE Hatch Mott MacDonald 220 West Garden Street, Suite 700 Pensacola, Florida 32502 SUBJECT: Geotechnical Exploration Proposal Meigs Drive Pavement Shalimar, Florida Dear Mr. Jenkins: Larry M. Jacobs & Associates, Inc. (LMJ) sincerely appreciates the opportunity to submit the following proposal for providing a geotechnical exploration for the subject project. The purpose of the exploration is to determine the subsurface conditions in the pavement area and use this information to provide recommendations for earthwork and pavement design. The following sections outline our recommended scope of services, a cost estimate for providing these services, and the proposed terms and conditions. PROJECT AND SITE DESCRIPTION The project site is located on Meigs Drive where it crosses Lake Vivian in Shalimar, Florida. Reportedly, the project consists of the replacement of roughly 500 feet of Meigs Drive, as well as raising the grade of that length of the road about two feet. We understand that the project includes the construction of a new culvert with headwalls. Reportedly, the roadway is known to flood. If any of this information is incorrect, please let us know as it may require changes to our scope. PROPOSED SCOPE OF SERVICES The following proposed scope of services is based on the information supplied and our experience in the area with similar projects. We propose to perform the following: ▼ Locate the borings at the site with a hand held GPS unit. ▼ Clear registered utilities at the site with the Sunshine Network. Non-registered or private utilities are the responsibility of the client to clear. ▼ Mobilize a truck mounted and tripod mounted drill rig(s) and drill team to the site. ▼ Use proper MOT to close one lane of Meigs Drive to allow drilling operations, and we have included prices for sign rental and two flagmen. If the county or city will provide flagmen, we can forgo that fee. Drilling operations are expected to take roughly 1-1.5 days. ▼ Core the asphalt pavement at two locations (4 inch diameter) in order to obtain accurate information on existing pavement thickness. ▼ Patch core holes after completion of drilling operations. ▼ Drill 2 Standard Penetration Test (SPT) borings to a depth of 15 feet in the new roadway at the core locations. Since grades are being raised about two feet, these borings are being drilled deeper than normal roadway borings to check for the presence of compressible peat or clay. ▼ Drill 2 SPT borings at the culvert headwall locations to a depth of 25 feet, and these borings will be drilled with our portable tripod mounted drill rig since access is difficult and narrow.

Our proposal includes a small budget for basic properties testing like natural moisture content, Atterberg limits and sieve analysis to evaluate and document basic soil properties. ▼ Analyze the test data to develop geotechnical engineering recommendations for the project. A professional geotechnical engineer licensed in the state of Florida will manage the project, and the results of the exploration will be presented in a report that will address the following: ▼ Existing site characteristics. ▼ Explorati
