Okaloosa County BOCC — April 7, 2015 — Task Order Number 4 Design Bidding Construction Admin and Inspection Services — reading text

Proposed Field Exploration Based on a review of the provided information and discussions with the design team, we propose to perform the following field services for this project: - Four (4), 40-foot deep SPT borings to be drilled on approximate 80-foot centers along the proposed wall alignment. Upon completion of the borings, the depth to groundwater will be measured. Soil cuttings from the drilling process will be used for backfilling of the boreholes. e Laboratory Testing Our proposed laboratory-testing program will include visual classification of the soil samples collected during the drilling process in accordance with the AASHTO classification system. Laboratory testing may also include limited classification tests (grain-size analyses, Atterberg limits and natural moisture content determination) of representative soils, if deemed necessary. In accordance with the attached General Terms and Conditions, soil samples will be disposed of 30-days after submittal of the final report, unless requested otherwise by the client. e Evaluation and Report Upon completion of the field exploration, we will evaluate the data obtained and prepare a written report for the site summarizing the findings, along with our conclusions and recommendations. We will keep you informed of our progress and findings throughout the course of the exploration. If poor or unanticipated subsurface conditions are encountered, we will contact you to develop a revised scope for our services prior to proceeding. A professional engineer registered in the State of Florida will prepare the report. NOVA ENGINEERING AND Page 2 0f6 ENVIRONMENTAL DTS Sound Barrier Wall March 12, 2015 Michael Baker International NOVA Proposal 1615058-GT Our written report will include the following: » A description of the site, fieldwork, laboratory testing and general soil conditions encountered, as well as a Boring Location Plan, and individual Log of Boring Records. > Site preparation considerations that include geotechnical discussions regarding site stripping and subgrade preparation, and engineered fill/backfill placement. » Recommendations for controlling groundwater and/or run-off during construction and, the need for permanent dewatering systems based on the anticipated post construction groundwater levels. » Drilled shaft and ACIP pile foundation recommendations for the proposed sound barrier wall, as well as applicable installation considerations. » Suitability of on-site soils for re-use as structural fill and backfill around the wall. Additionally, the criteria for suitable fill materials will be provided. » Recommended quality control measures (i.e. sampling, testing, and inspection requirements) for the sound barrier wall installation. NOVA will inform you of any obvious odors or materials seen during completion of our study. However, the assessment of site environmental conditions, the detection of pollutants in the soil, rock or groundwater, or laboratory-testing of samples, wetlands evaluation, or a site-specific seismic study are beyond the scope of this exploration. However, if requested, NOVA can also provide these services. o Site Utilities Prior to beginning field activities, NOVA will contact the underground locator service. They require 72 hours notice to mark utilities along the roadway right-of-way. Beyond normal due-diligence and working with the owner's personnel, we cannot be responsible for encountering utilities. Please note that NOV A has assumed that any permits for access, land and/or wetlands disturbance, tree cutting, etc. will be obtained by the CLIENT prior to our mobilization on site. Additionally, boreholes will be backfilled after completion with soil cuttings from the drilling process and some future subsidence of the boreholes should be anticipated. No site restoration is planned and no monies have been budgeted for such. If NOVA is responsible for site clearing to access specific boring locations, any aforementioned permits, fees, site restoration, etc. are assumed to be our Client’s responsibility unless we are specifically made aware of such at the time of authorization, which will result in adjustments in our budget and schedule. e Schedule Based upon our current schedule, we can begin the geotechnical scope of work for the project immediately after receiving written authorization to proceed. Our field team can likely mobilize to the site within a few days of the utility locates being completed. We anticipate that fieldwork will take 2-3 days to complete. The final geotechnical report will be submitted within 1 week of the completion of the field work. If the report is needed sooner, NOVA will make every reasonable effort to accommodate your schedule.

Testing, inspection and engineering services requested will be performed in general accordance with current building codes, ASTM and AASHTO standards, as well as reviewed contract documents when completed and available. Specifically, our proposed scope of services is outlined on the following pages. e Site Preparation and Grading » Document that the sound barrier wall alignment has been properly stripped of topsoil, vegetation and any other deleterious materials found to be present prior to fill placement. » Perform laboratory testing of native and proposed fill soils to determine their suitability, and moisture content versus dry density relationship (i.e. Proctor compaction testing, Atterberg limits determination, and/or sieve analysis, as applicable). » Provide qualified personnel for observing structural fill and backfill placement, and perform field density and moisture content tests at the frequency specified in the project specifications. e Foundations » Provide qualified personnel to monitor the installation of either drilled shaft or ACIP piles. e Concrete Construction » Sample and test plastic concrete, and mold either five compressive strength cylinders (47x8”) per set for a drilled shaft foundation, or two (2) sets of six grout cubes per day’s production for an ACIP pile foundation. Testing of the plastic concrete for drilled shafts will include measurement of its slump, air content and temperature, and tests for ACIP pile grout will include measurements of flow and temperature. Frequency of sampling/testing will be conducted in general accordance with contract documents. » Secure and transport initial field cured samples to our laboratory where they will be stripped, logged, prepped and final cured in submersion tanks. » Perform laboratory compressive strength tests on cured specimens. e Coordination Experienced Engineering Technicians, Inspectors or Engineering personnel will be assigned tasks as scheduled by the client’s and/or the contractor’s representative. We request a 24-hour notice when scheduling field services by contacting NOVA at 850-607-7782.
