Attachment A SCOPE OF SERVICES CITY OF SAN MARCOS PROPOSED SESSOM CREEK WASTEWATER CAPACITY IMPROVEMENTS PRELIMINARY DESIGN, DESIGN, BID, AND CONSTRUCTION PHASE PROJECT UNDERSTANDING The City of San Marcos has identified the existing wastewater line generally running along Sessom Drive, University Drive, and C.M. Allen; from immediately north of the Texas State University campus to the IH -35 feeder road; as a system bottleneck when considering future system flows under redevelopment scenarios. The line consists of approximately 7,200 linear feet of pipe, 12- inches through 24- inches in diameter, at depths of up to 20 -feet. Additionally, the City is reconstructing N. LBJ Drive and desires to install approximately 3,200 linear feet of 12 -inch wastewater line to relieve existing and future bottlenecks in the system upstream of the Sessom /University line. K Friese & Associates, Inc. has substantially completed a preliminary study that evaluated several options to increase the capacity through this area. The selected alternatives include pipe bursting, line replacement, parallel lines, and new installations. Since the final means of capacity improvement has not been selected, and several combinations of the capacity improvement methods are possible, this proposal assumes that 7,200 linear feet of new pipeline will be installed in the University /C.M. Allen area and 3,200 linear feet of new pipe will be installed during the reconstruction of N. LBJ Drive. The City has indicated that three separate construction contracts may be required. One construction contract will install new pipe through the Texas State University Campus, one will install new wastewater line downstream of the Texas State University campus, and the third set will be incorporated into the N. LBJ Drive reconstruction project. This proposal includes the necessary services to develop two complete sets of construction documents and one set of construction plans, all with separate bid and construction schedules. A. Basic Scope of Services Phase A — Preliminary (30 %) Design Phase (University /C.M. Allen Line) Project Management and QA/QC — This task includes routine communication with the City; managing subconsultants, manpower, budgets, and schedules; invoicing; implementing and monitoring of QA/QC efforts; and other activities associated with managing the project. Additionally, the Project manager will maintain an "issues list" identifying the date the Project related issues become known, the person(s) responsible for solution(s), date solutions(s) will be provided, and final resolution of the issue. 2. Project Meetings — Two project status meetings have been budgeted for the Preliminary Design Phase. 3. Data Gathering and Base Mapping — KFA will work with the City and other entities to obtain information necessary for the Preliminary Design Phase. Specific information gathered may include utilities (specifically storm sewer), 0FRIESE Page 1 of 10 & ASSu( 'n rF< Iv;.
