Specifications include, but are not limited to: The objective of this solicitation is to engage a qualified contractor to fulfill the role of Construction-Manager-at-Risk (CMAR) as further stated within this document, joining a team consisting of the Arizona Department of Administration (ADOA) and the Design Professional. The intended delivery method for this project is “Construction Manager at Risk” (CMAR), which consists of a Preconstruction Phase and a Construction Phase with separate contracts awarded for each phase. During the Preconstruction Phase, the selected contractor’s/firms will collaborate with ADOA and the Architect/Engineer on the design, constructability, cost, and scheduling of the entire project and develop one or more Guaranteed Maximum Price (GMP) proposals to construct the resulting facilities. This project will consist of two phases. Phase 1 will encompass the installation of a new Bioclere* package water treatment plant, refurbishment and reuse of certain bio-reel structural members, modification of existing sump located at the maintenance building to be tied into the new WWTP, installation of a new L B Foster / CXT concrete restroom building with new septic and leach field system. Also the decommission, demolition, haul off and disposal of the existing wastewater treatment facility. Phase 2 of the project will be the construction of a primary water source delivery system to the park's 50,000 gallon potable water storage tank based on discoveries of hydrological analysis. The project is located at 2980 AZ-90, Benson, AZ 85602. The combined estimated construction cost for this project is 6.5 million dollars for phase 1 and phases 2. The estimated construction duration of Phase 1 is 9 months, Phase 2 construction duration is to be determined upon primary water source confirmation. This project will utilize ARPA/state funds and is subject to the requirements of A.R.S. §41-791 * Bioclere™ is a modified trickling filter over a clarifier (settling tank) that is designed to treat wastewater with varying organic and nutrient concentrations. Within the Bioclere filter, wastewater is evenly distributed over the surface of plastic media where microorganisms known as biomass attach themselves to the media and consume BOD/COD and ammonia-N. Residual solids from the treatment process settle in the clarifier below the filter and are evacuated by a recirculation pump while clean effluent leaves the system by gravity.
