91. CONSTRUCTION MANAGER AT RISK CONTRACT FOR PARADISE RIDGE DRAINAGE IMPROVEMENT PROJECT – PRE-CONSTRUCTION Authorize the Flood Control District of Maricopa County (District) to issue a Request for Qualifications for a qualified construction manager/general contractor to provide Construction Manager at Risk (CMAR) services under Contract (2022C029) for the Rawhide Wash Flood Hazard Mitigation Pre-Construction (Project) and award a Pre-Construction services contract to the successful respondent not to exceed $500,000. Authorize the District to award the pre-construction services contract FCD 2022C029 to the selected respondent and pending negotiation of a mutually acceptable Guaranteed Maximum Price, authorize the District to award one or more construction services contracts to the selected respondent. The estimated total cost of the construction contract(s) is $30,000,000. This is a qualification-based selection in accordance with Maricopa County Procurement Code, Article 5, Paragraph 504(F) and Article IV of the Maricopa County Procedures Manual. The Flood Control District of Maricopa County has initiated design work for the Paradise Ridge Drainage Improvement Project under a consultant contract with Wood-Patel. The City of Phoenix is the project partner. The Project includes a channel, sediment basin(s) and associated improvements within the Rawhide Wash corridor from Scottsdale Road to SR-101. This is a complex project and, as such, the District will select the CMAR Contractor based on qualifications in order to obtain valuable constructability input during the design effort through delivery of pre-construction services under the Construction Manager At Risk contracting method. The future construction cost is currently estimated to be 30.0 million dollars. This Agenda Item impacts Supervisorial District 3. (C-69-22-096-X-00)

84. AMENDMENT TO CONSTRUCTION MANAGER AT RISK FOR PARADISE RIDGE DRAINAGE IMPROVEMENTS (Supervisorial Districts: 2 and 3) Amend the authorization for contract FCD 2022C029 under agenda Item number C-69-22-096-X-00 for the Flood Control District of Maricopa County (District), which authorized the award of a Pre-Construction Service contract and a Construction Service contract. This amendment authorizes the District to award Construction Services contracts to Sundt/Rummel, a Joint Venture, for a total contract amount not to exceed $68,000,000 without additional Board action. Sundt/Rummel Joint Venture (SRJV) was selected under a qualification-based selection in accordance with Maricopa County Procurement Code, Article 5, Paragraph 504(F) and Article IV of the Maricopa County Procedures Manual. The design work for the Paradise Ridge Drainage Improvements Project (Project) is well underway for the Flood Control District of Maricopa County under a consultant contract with Wood-Patel. The Cities of Phoenix and Scottsdale are project partners. The Project includes a channel, sediment basin(s) and associated improvements within the Rawhide Wash corridor and Deer Valley Channel from east of Scottsdale Road to SR-101. This is a complex project and, as such, the District selected the CMAR Contractor based on qualifications to obtain valuable constructability input during the design effort through delivery of pre-construction services under the Construction Manager At Risk contracting method. A phased approach is planned for construction of the Project by issuing three separate Guaranteed Maximum Price (GMP) contracts to SRJV. GMP 1 will allow SRJV to mobilize for the project, clear the site and excavate the channel and basins areas. Notice to proceed (NTP) for GMP 1 is anticipated to be issued before the end of May 2026.GMP 2 involves constructing the major structural components necessary to prevent the scouring of the channel banks and basins excavated as part of GMP 1. This will include constructing soil cement channel banks and cast-in-place concrete structures. Coordination will be required with ADOT for the portions of the project located within its right-of-way. NTP for GMP 2 is planned to be issued in July 2026. GMP 3 involves coordinating with the City of Scottsdale to construct box culverts under Scottsdale Road to pass flows from the east under the road into the Deer Valley Channel. NTP for GMP 3 is planned to be issued before the end of Calendar Year 2026. The Project was identified as the final step to a comprehensive solution to control alluvial fan flooding along the Rawhide Wash corridor. The project includes design of a channel system and associated structures to contain and convey the 100-year flood within Rawhide Wash and Deer Valley Channel from just upstream of Scottsdale Road to the SR-101 culvert system.
