This will include contacting the applicable One Call agency and associated utility owners/municipalities to request records and reviewing available utility record information obtained. • TRG will attempt to designate the following utilities within this area: potable water, reclaimed water, chilled water, natural gas/crude oil/refined product pipelines, communication duct banks, fiber optic, cable television, telephone, and electric. • Wastewater and storm drain facilities will be inverted at manholes, and will be depicted as QLC information. • TRG will attempt to designate utility service lines, however, because these lines are often non-conductive and not shown on records TRG cannot guarantee all service lines will be included in the final deliverables. • The following facilities/items are specifically excluded from the scope of work of this proposal: irrigation lines, overhead utilities, and detailed vault investigations. • TRG will attempt to provide Electronic Depth readings calculated by TRG's geophysical equipment. If Electronic Depth readings can be obtained, they will be provided every 50 feet. However, due to the inconsistency with Electronic Depth readings, TRG cannot guarantee the accuracy of the information. Data will be provided for informational purposes only. This proposal also includes up to sixteen (16) QLA SUE test holes at locations that will be provided by the Client following a review of the QLB SUE information. TRG has made the following assumptions related to test hole excavations on this project: • Test holes will be excavated using vacuum excavation equipment. • All test holes will be accessible to truck/trailer-mounted vacuum excavation equipment. Any special requirements needed to access test hole locations (clearing, grading, mat installation, etc.)will be provided by others at no cost to TRG. • Right-Of-Way (ROW) permits from the City of San Marcos will be required. TRG will obtain all required City permits and ensure that coordination and compliance with the City is provided. • Designed traffic control plans will not be required. • Traffic control measures will be required. TRG will acquire the services of a qualified Maintenance-Of-Traffic (MOT) Subcontractor, and ensure that adequate traffic control is provided. • Pavement coring/repair will be required. TRG can core pavement up to a depth of 12 inches. Asphalt surfaces will be repaired with an asphalt cold patch, and concrete cores will be epoxied in place, flush with the surrounding surface. • The following item is excluded from this scope of work: full-section pavement repair (including sidewalks) • Excavation in rock, or to a depth greater than 18 feet, is considered beyond the scope of this proposal.
