Innovative Technologies and Techniques In addition to our full suite of geophysical equipment, T2 offers a host of innovative equipment, services and approaches to utility investigations. Although not applicable for every project, T2's expertise will assist the City with deciding when and where such techniques may be appropriate. Perform Advanced Geophysics Investigation Multi -Channel GPR (MCGPR) is a relatively newtechnologyto the Utility Engineering industry. T2 uses the Stream EM and Stream C, which are MCGPR solutions dedicated to utility locating and mapping. These units employ 40 separate channels with double polarized antennas enabling the system to gather data both longitudinal and transversal simultaneously. The high number of antennas increases the quality of the data and allows our crews to detect utilities at greater depth, even in sub -optimal soil conditions. Stream EM and Stream C are equipped with a GPS unit that enables the data set to be easily georeferenced to the project survey datum. The system is towed behind a vehicle permitting technicians to gather the GPR data using minimal traffic control — reducing impacts to local traffic and improving field team and general public safety. Tasking • Mobilize advanced geophysical equipment to site. • Review with clients where test holes may be necessary to calibrate advanced geophysics tools. • Perform a MCGPR sweep of the site using the STREAM EM and/or STREAM C where applicable. • Prepare deliverables showing results of each of the above technologies. Prepare 3D Deliverables Collect data and compile a 3D utility model per ASCE 38-02 showing the horizontal location of the underground utilities at the achieved Quality Level over the project area. The drawings will be completed in AutoCAD or MicroStation and referenced into the design drawing. • Record electronic depths to the Quality Level B investigation. T2 will provide estimated depths at specific points from records/field measurements and geophysics and document the readings. Geophysical depths are noted and are not assumed to be a definitive measurement of utility depth. 2. SCOPE AND SCHEDULE 116
