Subject: Proposal for Subsurface Exploration and Groundwater Table Measurements 8th Street Roadway Improvements From 6611 Avenue to 82nd Avenue Vero Beach, Florida Dear Mr. Good: August 8, 2024 Proposal File No. 24-P-5599 As requested, we are pleased to present the following proposal for performing a subsurface exploration, installing piezometer wells, and collecting groundwater table measurements for the subject project. We understand that the project involves the roadway improvements along 8th Street starting from 66th Avenue to 82nd Avenue. The purpose of this work is to obtain general subsurface soil stratigraphy and groundwater level data to be used by the Client in designing the proposed stormwater improvements. The following summarizes our proposed scope of work and associated fees for conducting the subject exploration that was requested. FIELD EXPLORATION Our field program will include conducting three Standard Penetration Test (SPT) borings to 25 feet and five auger borings to 10 feet at accessible locations to our truck -mounted drill rig. We will also conduct 45 hand auger borings to 6 feet at the vicinity of the locations provided by the client. The SPT borings will be drilled using a procedure similar to the Standard Penetration Test outlined in ASTM D-1586 and will be sampled at 18 -inch or 24 -inch intervals to 10 feet deep and at 5 -foot intervals below 10 feet. The auger borings will be drilled to a depth of 10 feet below existing ground surface at the requested locations and will be performed using a 4 -inch diameter, truck- mounted continuous -flight auger. The hand auger borings will be performed using a 3 -inch diameter, hand-held bucket auger. Each sample will be removed from the sampler or auger in the field and then examined and visually classified by crew chief. Representative portions will be sealed and packaged for transportation to our laboratory for further analysis as required. Water level observations will be made in the boreholes during the drilling operation. We will also perform a series of muck probes for two days within the existing canal on the north and south sides of the 8th Street between 66th Avenue and 82nd Avenue that may be incorporated in the proposed roadway improvements. The muck probes will be performed by pushing a steel 460 NW Concourse Place, Unit 1, Port St. Lucie, Florida 34986 Phone (772) 878-0072 Fax (772) 878.0097 Florida: Bartow, Cocoa.
