The City of Phoenix is seeking a qualified consultant team to provide Engineering services for the

Sub-Regional Operating Group 91st Avenue Wastewater Treatment Plant Aeration Rehabilitation

Design. Services may include engineering analyses, design, permitting, programming, and possible construction administration and inspection services. The project site is located at 5615

S 91st Avenue, Tolleson, AZ 85353.

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. 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. Digested sludge is dewatered using centrifuges in the Solids Handling Facility and then hauled off-site for land application.

There are multiple aeration basins on site, fed by process air from five blower buildings. Plants 1, 2, and 3 are fed by three blower buildings connected to a common air header. Unified Plants 01 and 05 are fed by a dedicated blower building, as is the Centrate Treatment Facility.

The City intends to engage the services of an engineering consultant team to provide design and construction administration and inspection services for the rehabilitation of the facilities and equipment used to provide air to the treatment process. This project will include the rehabilitation or replacement of facilities and equipment associated with providing process air, including, but not limited to:

• Blower buildings o Roofs, drains, HVAC systems, bridge cranes, doors, and roll up doors;

o Structural columns, beams, and system structural supports;

o Electrical, instrumentation, and control systems including conduit and wire;

o Motor control centers; and o Variable frequency drives.

Page | 3

• Ancillary support systems o Air intake plenums;

o Bag houses;

o Filters;

o Blower cooling systems; and o Air compressors.

• Blowers o Motors;

o Piping;

o Guide vanes;

o Valves;

o Programming; and o Instrumentation and controls.

It is anticipated the design and construction necessary to complete the project scope will occur over multiple fiscal years with multiple construction, equipment procurement and equipment installation packages being required.

Scope of Work

Based on the 91st Avenue WWTP Facility Assessment, assessment updates, and previously completed work, 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 consultant may include, but are not limited to, the following:

• In conjunction with City Engineering, Plant Operations and Maintenance staff, and the selected Construction Manager at Risk (CMAR), the Engineering consultant will:

o Conduct field review(s) of the equipment, facilities and systems identified in previous process air facility assessment to identify, catalog, and prioritize the assets to be rehabilitated or replaced;

▪ Perform assessment site visits to the 91st Avenue WWTP. The intent of assessment site visits is for the engineering firm and City personnel, including engineering, and operations and maintenance staff, to jointly observe, discuss, and assess existing conditions of plant air process facilities and equipment, and identify needs for repair or replacement, along with equipment preferences. The evaluation is intended to confirm baseline needs for repair or replacement of equipment and associated items to be included in the preliminary design.

Page | 4 o Identify the scope, level and detail of construction drawings necessary to accomplish the project objectives. It is anticipated the replacement of most assets may require minimal construction drawings. At a minimum, only structural, electrical or control work requiring permitting will require construction drawings;

o Develop an initial schedule for the rehabilitation and replacement of the assets.

Schedule shall be prioritized based on the results of the field review(s), shall include and be cognizant of plant operations and maintenance schedules, and incorporate input from the CMAR regarding need for detailed design packages, equipment procurement schedules, and construction timeframes; and o Perform necessary engineering and life-cycle cost analyses to provide recommendations for replacement equipment.

• Compile existing record drawings of the process air facilities and conduct field surveys as required to provide accurate base drawings for those tasks requiring construction drawings;

• Develop a complete set of contract documents including construction drawings and specifications adhering to current City standards, regulatory guidelines, and requirements;

• Attend regular meetings with the project team to discuss, coordinate, and review the work progress and budget, resolve design issues, and document meeting minutes;

• Obtain all required permits for the construction and operation of the modifications;

• Provide all required services as necessary to implement alternative design reviews, constructability reviews, and quality control reviews that may be performed by the CMAR;

• Provide design services including agency coordination, preparation of preliminary, pre-final and final plans, consultation regarding the CMAR models and final cost proposal, and assistance in the bid evaluation and recommendation of contract award;

• Provide design services including agency coordination, and preparation of preliminary, pre-final and final contract documents;

• Provide consultation regarding the CMAR cost models and final Guaranteed Maximum

Price (GMP) proposal review, and prepare recommendation of contract award;

• Review and provide recommendations on value-engineering proposals developed by the

CMAR;

• In conjunction with City engineering, plant operations and maintenance staff, the Water

Asset Management (WAM) Core Team and the selected CMAR, the engineering firm will coordinate the updating of the WAM system and database and ensure the completeness and accuracy of information provided to the WAM system;
