(DE &T) is pleased to submit this scope of services <br /> letter in connection with the planned 20th Avenue Bridge project in Indian River County, <br /> Florida. Our services will be provided under our continuing Geotechnical Services Contract <br /> (RFP #7018) with Indian River County (January 2005 through January 2006) . In general , our <br /> services will involve performing field and laboratory quality control (QC) testing, including test <br /> pile driving oversight. <br /> We understand that the project will involve construction of a new bridge to allow access from <br /> existing Aviation Road to the proposed Indian River County Administration Complex. The <br /> construction will include the new bridge and a short section of roadway. Based on the <br /> discussions at the February 21 , 2005 per-construction meeting with you, we envision that our <br /> services will primarily involve the periodic performance of field and laboratory tests in <br /> connection with roadway/embankment construction, storm pipe installation, and bridge <br /> construction. A more specific listing of the services which we anticipate providing for the <br /> project follows on the next page : <br /> Bridge Structures <br /> • Pile driving analysis (PDA) testing during test pile installation and development of <br /> recommendations for production pile lengths and final driving criteria. <br /> • Periodic testing of concrete during substructure and superstructure construction. This <br /> will include slump, temperature and air content of plastic concrete, and compressive <br /> strength testing of hardened specimens . <br /> 523A NW Enterprise Drive, Port St. Lucie, Florida 34986 • (772) 343-9787 • Fax (772) 343-9404 <br />
