Docusign Envelope ID: B4237C90-FBOF-82E3-836F-A5CFD2F500AA C42 North Side 12 In Water Connection aka William Pettus Extension City of San Marcos Engineering Design Services Exhibit B Services to be Provided by the Engineer 2. Surveying Services BGE shall perform supplemental research and field surveying outside the limits of the County project to provide a waterline route, easement field notes, and locating up to two (2) bore holes. The following surveying services shall be conducted for the Project: a) Establish Site Control —3 primary points. b) Topographic, Tree, Boundary Verification Survey i) Topographic and boundary verification survey, along the Phase 1 and Phase 2 waterline alignment, outside of the County project limits, sufficient to produce 1' contours. Project controls shall be established with a minimum of three (3) monuments set. All visible utility and surface features shall be surveyed within the project limits, including inverts and top of lids. ii) Tree survey along the Phase 1 and Phase 2 waterline alignment, outside of the County project limits. All trees 9" and above shall be surveyed and tagged. iii) Locate two (2) bore holes. c) Easements field notes and sketches prepared with title commitments —6 permanent easements and 6 temporary construction easements. d) Record/As-Built drawing survey after construction is completed. This includes installed appurtenances and invert elevations. e) Deliverables: i) Topographic, boundary verification, and tree survey as Civil3D dwg. ii) Field notes for 30-foot temporary construction easements (6 total) and 20-foot permanent waterline easements (6 total). iii) Record/As-Built drawing survey. 3. Geotechnical Engineering The following geotechnical engineering services shall be conducted for the Project. The following geotechnical services shall be conducted for the Project: a) Perform Field Investigation— Up to two (2) borings will be completed: along the Phase 2 waterline alignment (up to 15-foot depth) and at the SH 21 trenchless crossing (up to 30-foot depth). Firm will be responsible for contacting the appropriate utility location services to have underground utilities located prior to drilling in the area. i) Soil borings will be properly backfilled with bentonite chips and a single lift of cold patch asphalt where applicable. The soil samples will be obtained using Shelby tubes and/or split- spoon samplers. Field testing of soil samples will include pocket penetrometer or Standard Penetration Test (SPT) in the cohesive soils and SPT in the cohesionless soils. ii) All field sampling and laboratory tests will be performed according to typical geotechnical standards or with other well-established procedures. Firm will perform appropriate laboratory tests on soil samples recovered from the borings. Laboratory testing may include moisture content, liquid limit, plastic limit, sulfate content, organic content, compaction, California Bearing Ratio (CBR) and particle size analysis tests. b) Firm will be responsible for avoiding conflicts with utility facilities by contacting the Texas One Call facility (Texas811). c) Provide geotechnical analysis and recommendations needed for utility excavation and backfill. 7
