Mr. Huy A. Ho, P.E. The City of Pleasanton August 13, 2013 Page 7 • Monthly progress summary reports. • Meeting agenda, action items, presentation materials, and meeting minutes. 2.0 Utility Coordination and Field Investigation This task is unchanged from the scope submitted April 10, 2012. 2.1 Utility Coordination: Carollo will contact affected utility companies and obtain existing utility information for incorporation into the design documents. Carollo will also attend meetings with these utilities as required to coordinate Jesign. Carollo will take a pro-active approach to keeping the utilities informed of Dur progress and in getting their feedback and comments as early as possible. 2.2 Potholing: Exaro Technologies Corporation, a subconsultant of Carollo, will pothole the location of existing utilities identified by Carollo. Exaro will use various techniques to locate the underground utilities, including ground penetration equipment, radar, tracer wire, radio technologies, or magnetic technologies. Once the utility is identified, Exaro will perform potholing using vacuum extraction methods to locate the elevation of the utility. Carollo will use this information to update the utility map of the project site. 2.3 Topographic Survey: Alexander&Associates, a subconsultant to Carollo, will provide ground control, field surveying, and office support required to prepare a topographic survey map of the project site and relevant surrounding area. The mapping will be prepared at 20 scale with a one-foot contour interval based on the City selected Datum. The mapping will also include surface features such as existing roads, existing pavement, sidewalks, fences, flatwork, driveways, buildings, and surface-visible utilities. Alexander&Associates will also show the property lines, easements and right-of-way on the topographic survey map. 2.4 Geotechnical: Jacobs Associates, a subconsultant to Carollo, will conduct a geotechnical investigation of the proposed pump station site by dr!ling three test borings for the project at locations agreed upon by Carollo and the City. The depth of the test borings will range from about 20 feet along the planned new discharge forcemain/gravity pipeline alignment to 50 feet at the wet well at the planned EARS Pump Station. It is assumed the City and DSRSD will provide encroachment perrnits, and Jacobs will not be required to obtain the permits. It is also assumed Jacobs will only provide a final Geotechnical report. Deliverables: • Utility map. • Two (2) days potholing and one (1) day of pavement restoration, which is approximately 10 pothole utility locates.
