Work Order No. 51 Aviation Boulevard Extension Alternative Alignment Study shaft foundations. The following summarizes our proposed scope of work and associated fees for conducting the subject exploration. FIELD EXPLORATION The requested field exploration program will include the following: The SPT borings will be drilled using truck -mounted drilling equipment and a procedure similar to the Standard Penetration Test outlined in ASTM D-1586. The borings will be sampled at 18 -inch intervals to 10 feet deep and at 5 -foot intervals below 10 feet. The auger borings will be drilled with a 4 -inch diameter, truck -mounted continuous flight auger or a 3 -inch diameter, hand-held bucket auger. Each sample will be removed from the auger or sampler in the field and then examined and visually classified by our 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. Upon completion of drilling, the boreholes will be backfilled with soil cuttings. In addition, four pavement cores will be performed collected within the project limits using a portable coring machine fitted with a 4 -inch diameter core barrel. The pavement cores will be performed to a maximum depth of 2 feet below the top of pavement surface. The asphalt cores and samples of the existing base and subbase materials (if present) will be packaged and returned to our laboratory for observation. Maintenance of traffic (MOT) services will be necessary to perform the pavement cores. The MOT services will be provided by a sub consultant that specializes in these types of services. One day of MOT services is included in this proposal. As requested, we will also install two 2 -inch diameter, PVC piezometer wells to maximum depth of 10 feet below existing ground surface at locations on the project site selected by Page 3 of I 1 Depth Below Ground Description Number of Borings Surface (feet) Mast Arm Pole Foundations - 4 SPT 40 US Highway 1 Mast Arm Pole Foundations — 36th Street 2 SPT 40 Stormwater Pond 4 SPT 25 6 Auger 10 Roadway Improvement Areas 24 Auger 6 The SPT borings will be drilled using truck -mounted drilling equipment and a procedure similar to the Standard Penetration Test outlined in ASTM D-1586.
