PARYK01»01M9ANIN16 MILlIN:111111:1:1B1l14 Underground Utility Locating T2 field technicians will perform air -vacuum excavation of test holes on existing subsurface utilities requested by the team. Our approach is to remove a small 12"x12" plug from the surface and excavate using an air lance to break the sub -grade up. This is the most non-invasive method of vacuum excavation and is favored over hydro excavation as it does not disturb the surrounding soils and allows for a stronger back -fill using native soils. Test hole locations will be identified during the development of the plans. Utility data obtained through our standard procedures includes the depth, horizontal and vertical location tied to a reference marker set 1' away from the test hole, size and material composition of the utility exposed. T2's general approach to test hole procedures is to begin by working with the City to identify preliminary areas where test holes may be required. We will begin the process by performing a records research campaign to ascertain the utilities are present and who owns those utilities. During this process, T2 will coordinate with the City to obtain any records or plans available that may show utilities and ownership. T2 additionally will contact One -Call to obtain utility records and a list of utility owners in the area. Depending on the location and City right-of-way requirements, Traffic control plans will be prepared and submitted for approval. T2 will hire a barricade firm from an approved vendor list to perform all traffic control if needed. Prior to commencing work, T2 field crews will ensure that all traffic control devices are set up according to the approved traffic control plans. Field crews will expose the utility, documenting the elevation of the top and bottom of the utility as referenced to the reference marker set in the adjacent grade, outside diameter or size of utility, material and pavement thickness, soils material and any other anomalies encountered. This information is documented on a Test Hole Data Report form using T2's proprietary software that captures all of the information and photographs of the hole. Completed and final Test Hole Data Reports are reviewed and stamped by T2's in-house PE. Schedule As stated above, T2's Project Manager and Task Managers hold regular project team meetings — with a major emphasis placed on reviewing progress and discussing upcoming milestones. The initial step is to create a realistic schedule including critical path items such as coordination with the City early in the scheduling process to verify the milestone submittal dates. Major work tasks will be planned as a series of subtasks and accommodate a bottoms -up approach at schedule development stage, a proper linkage of predecessor/successor activities and an effective management tool to track/adjust schedules or reallocate resources as work proceeds. 2.
