REQUEST FOR QUALIFICATIONS
The City of Phoenix is seeking a qualified consultant team to provide engineering services for the
rehabilitation of piping systems, mechanical equipment, structures and supports, electrical feed and
distribution systems and control systems related to the 91st Avenue Wastewater Treatment Plant 2B
treatment train. Services may include engineering analyses, design, permitting, programming, and
possible construction administration services. The project site is located at 5615 South 91st Avenue,
Tolleson, Arizona. The estimated total construction cost for this project is $34.65 million.
SECTION I PROJECT DESCRIPTION
The 91st Avenue Wastewater Treatment Plant (WWTP) is located on a 560-acre site just east of 91st
Avenue, south of Broadway Road and north of Southern Avenue. The plant is owned by the Sub-
Regional Operating Group (SROG) and operated by the City of Phoenix. The facility has the capacity to
treat 230 million gallons per day (MGD). Portions of the facility were built in the early 1960’s, and the
facility has been expanded and modified since then. The facility treats the wastewater with various
processes consisting of:
Screening
Grit removal
Primary sedimentation
Activated sludge with nitrification-denitrification
Secondary Sedimentation
Disinfection by chlorine
Dechlorination (sodium bisulfite)
Both primary and secondary solids are thickened using centrifuges in the Solids Thickening Facility prior
to digestion in sixteen anaerobic digesters using multi-phase digestion. Solids are fed to an acid-phase
digester then to multiple methane phase digesters. Digested sludge is dewatered using centrifuges in the
Solids Handling Facility and then hauled off-site for land application
Wastewater is treated at the 91st Avenue WWTP in one of seven treatment trains, or plants. Contained
within each treatment train is primary sedimentation, activated sludge aeration, secondary sedimentation
and effluent disposal.
The City intends to engage the services of an engineering consultant/consultant team to provide design
and construction administration and inspection services for the rehabilitation and replacement of
equipment throughout Plant 2B, including, but not limited to, primary sedimentation basins and
equipment, aeration basins and equipment, secondary sedimentation basins and equipment, pumps,
motors, piping, control instruments and panels, and electrical equipment including panels, variable
frequency drives, transformers, and motor control centers.
It is anticipated the design, construction administration and inspection, and construction necessary to
complete the project scope will occur over multiple fiscal years with multiple design, construction,
equipment procurement and equipment installation packages being required. The City intends to engage
the services of construction team utilizing the construction manager at risk (CMAR) delivery method to
complete the construction of the project.
SECTION II SCOPE OF WORK
Based on the 91st Avenue WWTP Facility Assessment previously completed, the selected engineering
consultant will review and prioritize the project scope items and make recommendations for the
rehabilitation and replacement of equipment, facilities, and systems necessary to meet the project goals.
Design services by the engineering firm may include, but is not limited to, the following:
Prepare a basis of design including life-cycle cost analyses to determine whether replacement or
rehabilitation should be implemented to address deficiencies within the following areas:
