Item 4K MemoItem 4K Page 1 of 2 M E M O R A N D U M (September 17, 2019) To: Shana Yelverton, City Manager From: Rob Cohen, Director of Public Works Subject: Approve an Engineering Services Agreement (ESA) with Baird, Hampton & Brown to provide design services for water line improvements located at Westpark Circle, T.W. King Road, and SH 114 in an amount not to exceed $75,320. Action Requested: Approve an Engineering Services Agreement (ESA) with Baird, Hampton & Brown to provide design services for water line improvements located at Westpark Circle, T.W. King Road, and SH 114 in an amount not to exceed $75,320. Background Information: The proposed ESA is to provide design services for water line improvements at Westpark Circle, T.W. King Road, and SH 114. These improvements will address fire protection concerns and improve water quality at the locations. The design plans include upsizing the water lines at Westpark Circle and along T.W. King Road from south of Westpark Circle intersection to north of Westpark Circle intersection. The Westpark Circle Subdivision is currently being serviced by an existing 2 -inch water line. The Fire Department has expressed fire protection concerns at this subdivision due to the lack of a fire hydrant along Westpark Circle. This project will design the upsizing of the existing 2-inch water line to an 8-inch water line and fire hydrants to address the Fire Department’s safety concerns. Along T.W. King Road, the existing water line is a 6-inch and will be upsized to a 12- inch and be relocated out of T.W. King Road’s pavement to improve accessibility for future maintenance. The project also includes connection of two water line dead-ends located along SH 114 Frontage road by Southlake Medical District. There is currently a 12-inch water line that dead-ends to the southeast of Southlake Medical District, while another 12-inch water line dead-ends at the northwest quadrant of the East Highland and SH 114 Frontage intersection. By connecting these dead-end segments, better circulation in the water system will Item 4K Page 2 of 2 improve water quality and eliminate the need to flush the stagnant water from the dead-end water lines. The scope with Baird, Hampton & Brown will include preparation of plans, specifications and estimates required for solicitation, and staff support during bidding and construction. Financial Considerations: Funding for the water line improvements located at Westpark Circle, T.W. King Road, and SH 114 is provided in the Utility and Water Impact Fee Funds from FY 2019 Capital Improvement Program budgets. This agreement is within the project budget. Strategic Link: This item links to the City’s Strategy Map strategic focus areas of Safety & Security, Infrastructure, and Performance Management & Service Delivery. It specifically relates to the City’s Corporate Objectives, C1: Achieve the Highest Standards of Safety & Security, B5: Enhance Service Delivery Through Continual Process Improvement, and F2: Invest to Provide & Maintain High Quality Public Assets. The Critical Business Outcomes is, CB05: Improve Quality of Life Through Progressive Implementation of Southlake’s Comprehensive Plan Recommendations. Citizen Input/ Board Review: None. Legal Review: The proposed agreement is a standard engineering services agreement that the City Attorney has reviewed and approved. Alternatives: The City Council may approve or deny the agreement. Staff Recommendation: Approve an Engineering Services Agreement (ESA) with Baird, Hampton & Brown to provide design services for water line improvements located at Westpark Circle, T.W. Kin g Road, and SH 114 in an amount not to exceed $75,320.

In addition, the project provides for construction of a new water line, along SH 114, needed to complete a distribution system loop. These water lines are needed to upgrade and complete the city’s water distribution system, and provide increased flow volumes and improved water pressures. The proposed improvements will include fire hydrants, valves and other appurtenances for a complete and functional system meeting today’s standard. Water Line construction and reconstruction will be by open trench and trenchless technology methods. These improvements consist of (1) replacing/enlarging 1,220 LF of existing 2-inch with an 8-inch water line within Westpark Circle, (1) replacing/enlarging 500 LF of existing 6-inch with a 12-inch water line along TW King Road, and (3) constructing 940-LF of a new 12-inch water along SH 114. Engineer’s Opinion of Probable Cost: From a budgetary perspective, and without the benefit a survey, we’ve prepared a budgetary Opinion of Probable Construction Cost (OPCC). This estimate will be refined as the project moves forward to the Concept Report, Preliminary Plans and Final Plans phases. Water Line Reconstruction w/in Westpark Circle (1,220 LF) $298,000 Water Line Reconstruction w/in TW King Road (500 LF) $103,000 Looping of Water System at SH 114 (940 LF) $227,000 Project Total Opinion of Probable Construction Cost $628,000 City of Southlake Westpark, TW King & SH 114 Water August 20, 2019 Page 3 of 6 City of Southlake Westpark Circle, TW King & SH 114 Water Line Improvements Project Summary Project Schedule: A detailed Project Schedule, which includes surveying, engineering, bidding and construction, has been prepared and enclosed herewith. The schedule has been prepared with assumptions as to the responsiveness of the franchise utility companies and the timeliness of city reviews.
