PROJECT OVERVIEW & BACKGROUND

Project -

The Quinault Indian Nation (QIN) seeks proposals from qualified design teams to provide

engineering and design services including, without limitation, preliminary and design

engineering, plans and specifications and stamped construction documents concerning the total

replacement of existing Wastewater Treatment Plant (WWTP), and integration with existing

collection system in Queets, WA. For the purposes of this RFP the term “project” means the

entirety of services listed above.

Approximately 190 people live in Queets, which is located on the Quinault Indian Reservation

(QIR) one mile from the coast of the Pacific Ocean. Erosion by adjacent waterways has

compromised the integrity of the existing wastewater treatment lagoons, failure of which would

result in discharge to Queets River and ocean. Due in part to the deteriorated condition of the

existing WWTP, the threat of spillage or seepage into the Queets River, and the viability of a

more resilient location, the Portland Area Indian Health Services issued a Finding of No

Significant Impact (FONSI) for the construction of a new WWTP.

This project will provide a new sewer treatment system for 5 commercial properties and 53

residences, with capacity to support growth and an anticipated volume of approximately

160,000 gallons per day. The new WWTP will be located in a more resilient location, at a

slightly higher elevation above the floodplain and outside the tsunami inundation zone, along

the western side of Highway 101. QIN is currently in the process of clearing and providing an

access road to the new location. A proposed lift station and force main will convey sewage from

the existing collection system to a new mechanical wastewater treatment plant with extended

aeration lagoons (four cells) and construction of a distribution system for discharge of reclaimed

water to adjacent creek.

The purpose of this Request for Proposals (RFP) is to select a consultant to provide engineering

services for QIN concerning new system design and engineering. The selected firm or

consultant will report directly to Contract Officer and Owner’s Representative.

Estimated Project Cost –

The Project is estimated to cost approximately $8,700,000.00.

Estimated Time Period –

Work on the Project is estimated to begin in 2026 and to be completed by 2027. The estimated

time period in which the Services (as defined below) will be performed will begin in the FALL

of 2026 and end in the MID 2027.

SCOPE OF SERVICES

The scope of services to be performed by the consultant pursuant to this RFP include, without

limitation, the following engineering services concerning the Project (collectively, the “Services”)

A. Location & Preliminary Engineering

• Site Survey

• Geotechnical report and Recommendations

• Complete environmental and archaeological investigations and reports

• Assist with USACE Clean Water Act

B. Design Engineering

• Complete design topographical surveys.

• Preparation of draft and final (30, 60, 90, and 100%) engineer design documents

including plans, specifications, contract documents, and cost estimates for

i. A new mechanical WWTP with a four-cell extended aeration lagoon system

1. Structural System

a. Design to meet current building codes and seismic requirements

b. Foundation system based on geotechnical recommendations

2. Mechanical Systems

a. HVAC system with individual zone control

b. Energy efficiency meeting current standards

3. Electrical Systems

a. Appropriate interior and exterior lighting

b. Occupancy sensors

c. Adequate power distribution for technology needs

ii. Distribution system for discharge of treated water to adjacent creek

iii. Associated access and parking for utility rigs and staff (7-8 parking spots)

emphasizing natural disaster resilience and low-cost maintenance upkeep.

iv. All necessary utilities and infrastructure connections including, but not limited to,

electricity, land line phone, broadband. As well as generator and UPS backup

system with minimum 72-hour power supply.

v. Full site security to include adequate full coverage lighting; security system

including cameras with remote control and communication capabilities (e.g.

Starlink); unbroken perimeter fencing (commercial grade, security fencing, min.

8’ tall) substantive enough to reasonably ensure public safety from - and safety of

WWTP from -wildlife intrusion, trespass, vandalism, and other human activities.

• Submit final design plans, specifications, and other documents to QIN and applicable

federal agencies for review and approval.

• Coordinate with QIN Environmental Protection staff and/or environmental consultants

for any wetland delineation, cultural surveys and other QIN and Federal environmental

review support, as needed.

C. Other Items – It is anticipated that other Project-related tasks could arise during the preliminary

engineering and/or design engineering phases. QIN’s Contract Officer and Owner’s

Representative will perform the role of project managers. The Project Managers will work

closely with the consultant team and answer questions, provide information and guidance, assist

in coordination, and make decisions on behalf of QIN.

DESIGN SERVICES

As described above, the contractor shall be responsible for providing comprehensive design

services for the Queets WWTP. The design process will proceed through distinct phases

outlined below.

Design Development and Review. The initial phase requires thorough review and analysis of

existing documentation and site conditions. The contractor will evaluate the provided

background documents and conduct comprehensive analysis including site verification, project

requirements, and project outcomes.

Design Phases. The design will progress through three formal phases, with each phase building

upon previous work while incorporating QIN feedback and requirements:

Schematic Design (30%): This phase establishes fundamental decisions about the WWTP

layout, systems, and expected capacity and performance through development of:

• Site utilization and development plans showing building placement

• Design and layout of infrastructure, equipment, and overall operations

• Building elevations illustrating exterior appearance and materials

• Basic building sections showing vertical relationships

• Basic design of exterior security systems, perimeter fencing

Page 3 of 11

• Preliminary outline specifications

• Initial cost estimates based on recommended design to meet expected capacity (160,000

gallons per day)

Design Development (60%): Building on approved schematic design, this phase resolves and

documents:

• Detailed, dimensioned floor plans for all spaces

• Interior elevations of all spaces

• Detailed building sections and wall sections

• Detailed security system, infrastructure, and redundant power supply designs

• Engineering plans for all building systems

• Material and finish selections with samples

• Updated cost estimate reflecting design development

Construction Documents (100%): The final design phase delivers comprehensive documentation

for bidding and construction including:

• Complete drawing set for all disciplines with PE’s stamp

• Final technical specifications

• Detailed cost estimates

• Final Engineers estimates

Required Documentation Throughout all design phases, the contractor shall maintain thorough

documentation including:

• Design calculations for all disciplines

• Energy modeling and performance analysis

• Building technology infrastructure plans

• Material samples and specifications

• Color and finish schedules

CONTRACTOR REQUIREMENTS

The selected contractor must demonstrate comprehensive qualifications appropriate for a project

of this scope and complexity. The contractor shall be licensed in Washington State and maintain

good standing throughout the project duration. The design team must include licensed

professionals across all required disciplines to ensure complete coverage of project needs.

The lead contractor must hold all necessary Washington State licenses and demonstrate the

aeration WWTP. The design team shall include licensed professionals in each required

discipline, including architectural, civil, structural, mechanical, electrical, and plumbing

engineering. The contractor must either hold or be able to obtain a QIN business license prior to

contract execution.
