RE: 
El Mirage WRF Filter Design-Build Project 
 
Lump Sum Fee Proposal for Design 
 
Dear Mr. Gordon: 
Attached is our scope of work and fee proposal for providing engineering design services for the City of El 
Mirage Design-Build project to install one new tertiary filter at the El Mirage Water Reclamation Facility. 
The project includes piping work for a pumped SER and re-routed overflow line back to the influent pump 
station, and consolidated discharge piping. 
The scope of work in this proposal includes civil, mechanical, electrical and structural design work, 
geotechnical evaluation, and permitting for county ATC and City permits. The fee for construction 
engineering services, including inspections, record drawings and AOC permitting will be provided 
separately prior to the GMP submittal to client.  Please contact Ms. Kagie-Hay at (602) 733-6149, (480) 
241-6622, or at andrea.kagie@woodplc.com with any comments or questions.  
We look forward to the opportunity to working with PCL Construction on this project. 
Respectfully submitted,

El Mirage WRF Filter Design-Build Project 
Wood Proposal No.: PW20-08-01 
October 5, 2020 
 
Page 1 
1.0 
Introduction 
The City of El Mirage (City) needs a filter upgrade and improvements to the chlorine injection system. 
Timing is critical with flows from a new data center coming online soon. Wood Environment & 
Infrastructure Solutions (Wood) and PCL Construction, Inc. (PCL) have teamed up to provide Design-Build 
services for the installation of a new tertiary filter and associated improvements. The costs to the City will 
be presented in two parts: 
• 
GMP 1 will include Wood’s design fees to reach full design with required permitting assistance, 
PCL’s preconstruction services, and the costs required for the purchase of the tertiary filter, as this 
will be ordered as soon as possible. 
• 
GMP 2 will include the remainder of the costs associated with project, including all construction 
scope, construction engineering services, record drawings, close-out permitting, inspections, and 
materials testing. 
Wood is providing PCL with a complete design fee in this proposal and will follow up with the costs to be 
included in GMP 2 in a subsequent proposal to be presented during the design phase. This document 
provides details of the scope of services that are included in this fee and proposal. 
1.1 
Background 
The City owns and operates the El Mirage Water Reclamation Facility (WRF), a 2.5-million gallons per day 
(mgd) tertiary wastewater treatment plant. The facility operates a sequencing batch reactor (SBR) 
treatment technology and produces Class A+ effluent. The facility requires the addition of a fourth tertiary 
filter for several reasons, including the need for redundancy and the construction of a new data center in 
their service area increasing flows up to 186,000 gallons per day (gpd). The facility will also likely require 
an expansion in the coming years to keep up with the increasing demands expected from new residential 
developments that are planned within the service area. This project will expand the tertiary filtration 
capacity with the addition of a fourth filter and make operational improvements to the filter piping and 
chlorine injection. All design must take the future expansion needs into account for feasibility and cost 
effectiveness of this project and the future expansion project. 
The following sections describe the tasks required within the scope of work for this project. 
2.0 
Task Descriptions 
The scope of services and fee proposal provided in this proposal are based on the original Request for 
Qualifications (RFQ), PCL-Wood’s joint Statement of Qualifications (SOQ), a scoping discussion with the 
City and PCL via conference call on September 22, 2020 and a scoping site visit with the City and PCL on 
September 25, 2020. 
The following sections review the proposed scope of services, broken down into tasks and sub-tasks. 
2.1 
Task 1 – Project Management  
Wood will provide project management for the Project Team under Task 1 that will include project 
management, coordination, and up to five (5) design-phase meetings. The specific tasks are broken down 
as follows:

El Mirage WRF Filter Design-Build Project 
Wood Proposal No.: PW20-08-01 
October 5, 2020 
 
Page 2 
Task 1100 – Project Management and Coordination 
Under this task, Wood will monitor and track the project budget and progress to ensure that deadlines 
are met, and the project budget is not exceeded. Wood will keep PCL and the City informed as needed 
and prepare consolidated invoices for submittal to PCL on a monthly basis. Wood will communicate with 
PCL via email and phone calls, as needed throughout the project to ensure the project needs are fully 
understood and addressed. 
Task 1200 – Project Meetings 
This task will consist of organizing, attending, and conducting up to five (5) design meetings. The project 
Team will consist of PCL, Wood, City staff and subconsultants and sub-contractors, as required. Wood will 
provide a meeting agenda prior to each meeting and meeting notes that summarize any decisions and 
actions items resulting from each meeting. 
The meeting scope includes a kick-off meeting, a 30% design concept review meeting, and up to three (3) 
design review meetings coordinated with the design submittal milestones. Design review meetings will be 
held two weeks after each design submittal to allow the City time to review the submittal. Although not 
necessary, it would be preferable to have the City provide Wood with their review comments prior to the 
meeting so they can be discussed in more detail at the meeting. Wood will utilize the design review 
comments and discussion at these meetings to continue forward with the next phase of the design. 
2.2 
Task 2 – Basis of Design Report 
The work product developed through the sub-tasks for the Basis of Design Report (BODR) task will 
provide the basis for the design of the filters and related improvements. This task includes background 
work, geotechnical investigation and the upfront filter equipment design to allow for ordering the filter as 
early as possible. The specific sub-tasks under Task 2 include the following: 
Task 2100 – Background Information 
Wood will review the background information relevant for this design. This task consists of gathering, 
organizing, and reviewing background information, including drawings and schematics for structural and 
electrical disciplines, permits, and plant data. Wood will also continue to work with plant personnel to 
ensure all constraints are accounted for in the design. 
Task 2200 – Geotechnical Investigation 
Wood will conduct a geotechnical investigation that will include drilling one boring to 20 feet and 
development of a geotechnical report to document localized site conditions for construction of the 
structural equipment pad for the tertiary filter and for the expansion of the Filter Gallery enclosure. 
Task 2300 – Filter Equipment Design 
The lead time for the tertiary filter is several months. Wood will prioritize developing the design 
requirements and specifications upfront to allow the filter to be ordered as soon as possible in the 
process. This sub-task includes working with plant personnel and the manufacturer to ensure the filter will 
meet all site requirements including hydraulic flows, and equipment preferences.

Wood Proposal No.: PW20-08-01 
October 5, 2020 
 
Page 3 
Task 2400 – Basis of Design Report 
Wood will develop a Basis of Design Report for the filter installation. The design report is necessary to 
obtain an Approval-to-Construct (ATC) permit through Maricopa County Environmental Services 
Department (MCESD) and the required City Fire, Building, and Life Safety Department (FBLSD) permits. 
The design report will include the sizing criteria, design criteria, and other information to show 
compliance with the existing plant permits. 
2.3 
Task 3 – Detailed Design Services 
The intent of the Detailed Design Phase of the project is to prepare a complete set of Design Drawings, 
technical specifications, cost estimates and Guaranteed Maximum Price (GMP) development assistance. 
Each sub-task will build upon the previous sub-task to develop the final product for construction. 
The filter improvements project includes not only the installation of a fourth new tertiary filter, but 
additional improvements to provide improved treatment and operational flexibility. The following is a 
simplified list of the main components and scope items that will be included in the design documents: 
• 
New filter installation 
o 
Design of equipment slab on grade based on geotechnical report 
o 
Providing power to the new filter equipment 
o 
Connecting the control panel to the plant SCADA via ethernet (programming not 
included in Wood’s scope) 
• 
New filter influent piping and valves 
• 
Secondary Effluent Recycle (SER) piping is to be routed to head of the plant upstream of the 
influent pump station (IPS) 
o 
Install flow meter on the line (potentially combining SER with OF for a single meter) 
• 
New filter discharge piping 
o 
All filter discharge piping is to be consolidated into a single discharge pipe that 
incorporates a single in-pipe chlorine injection point with an inline static mixer 
• 
New filter overflow (OF) piping 
o 
All filter OF piping is to be consolidated and re-routed to the head of the plant upstream 
of the IPS 
o 
Install flow meter on the line (potentially combining SER with OF for a single meter) 
• 
Provide a variable frequency drive (VFD) on the existing second filter feed pump to provide 
flexibility and efficiency in operation 
• 
Modify the Filter Gallery wall to enclose the new filter 
Key assumptions that will guide the design include the following: 
• 
The expansion that is planned for the near future will require the construction of new basins, all of 
which will be located to the north of the Filter Gallery and to the west of the existing SBRs. 
• 
The future Surge Basin and EQ Basin each will be hydraulically connected to its respective existing 
basin. Neither will require a direct connection to or from the influent pump station. Due to the 
proposed locations, future piping for these two basins are assumed to not interfere with the filter 
installation or general area of this current project. Design of the future basins’ connecting piping 
is excluded from this current project.

Wood Proposal No.: PW20-08-01 
October 5, 2020 
 
Page 4 
• 
An existing 18 or 21-inch sewer pipe comes from the north and feeds into the manhole located 
north of the existing flume that is upstream of the IPS. This pipe will need to be relocated prior to 
the future expansion and installation of a fifth tertiary filter. For the current project, both sewer 
pipe locations (current and future) will need to be considered while locating the SER and re-
routed OF piping. 
The specific tasks under Task 3 include the following: 
Task 3100 – 60% Design 
This design sub-task consists of developing design drawings at a 60% design level, a draft of the design 
specifications on the plans, with a fully-developed filter specification, and an outline of the main 
components of piping, valves and flow meters developed to 60%. The 60% design sub-task includes 
development of an initial Opinion of Probable Cost of Construction (OPCC) and assistance with the 
development of the GMP from an Engineer’s perspective. 
Task 3200 – 90% Design 
Wood will continue to develop the design documents up through a 90% design level, including the full 
set of specifications on plans, incorporating comments from the City and PCL at the 60% design meeting. 
The design documents will be ready for submittal for permitting pending any final comments from the 
City and PCL at the 90% design review meeting. This submittal will include an updated OPCC, and the 
sub-task will include any GMP assistance necessary. 
Task 3300 – 100% Design 
This task will capture any changes needed based on the 90% submittal review. The design documents will 
then be sealed and signed by an Arizona-registered Professional Engineer for each discipline. The design 
documents will then be submitted to MCESD and the City. Any comments received from MCESD and City 
permitting applications will be addressed and a final conformed set of design documents will be issued. 
The final design documents will include drawings, on-plan specifications, design report, and a final 
construction cost estimate. 
2.4 
Task 4 – Permitting 
Permitting assistance included in this proposal only includes the MCESD ATC application preparation and 
City of El Mirage permitting requirements. This proposal does not include any updates to the El Mirage 
WRF Aquifer Protection Permit (APP) issued through Arizona Department of Environmental Quality 
(ADEQ). This proposal also does not include any fees associated with the permits. It is assumed the City 
will pay all necessary permitting fees. 
Task 4100 – MCESD ATC 
Under this task, Wood will fill out the necessary paperwork and compile the required information needed 
to submit with the ATC permit through MCESD. Wood will address comments received from the MCESD 
and will provide any updates to the design package required to obtain the permit.

Design Notes
Filtration
- The cloth media filter recommendation and anticipated effluent quality are based upon influent water quality conditions as
shown under "Design Parameters" of this Process Design Report
- The anticipated filtered effluent quality is based on the filter influent conditions as shown under "Design Parameters" of this
Process Design Report.  In addition, the filter influent should be free of algae and other solids that are not filterable through a
nominal 10 micron pore size media.  Provisions to treat algae and condition the solids to be filterable are the responsibility of
others.
- For this application, pile filter cloth is recommended.
