Project Title: WTP Capacity Expansion (1.6 MGD to 2.7 MGD)

1. PROJECT SUMMARY

The City of Chelsea, Michigan (City) is soliciting Request for Quotations (RFQ) from

qualified engineering consultants to conduct Design Engineering and Bidding

Services to expand the City of Chelsea Water Treatment Plant (WTP) from 1.6 Million

Gallons per Day (MGD) to 2.7 MGD.

Important Scope Clarification: This RFQ is strictly for engineering design and bidding-

phase professional services (including permitting support). No construction-phase

engineering/administration services (including resident inspection, construction

observation, pay application review, change order review, submittal review, or RFI

response) are included in this RFQ. The City may, at its sole discretion and subject to

City Council authorization, procure construction-phase engineering services under a

separate agreement or separate authorization after award of this RFQ.

2. PROJECT BACKGROUND & EXISTING ASSETS

The Chelsea WTP, operational since 2001, utilizes iron filtration followed by membrane

softening.

Component

Current Specification

Groundwater

Wells

3 Wells; Firm Capacity: 2,100 GPM

Iron Filtration

2 Gravity Filters; Total Capacity: 1,400 GPM

Reverse Osmosis 2 Skids; Total Softened Water Flow: 1,120 GPM

Storage

200,000 Gallon Ground Tank; 400,000 Gallon

Elevated Tower

Component

High Service

Pumps

Current Specification

3 Pumps; Firm Capacity: 1,600 GPM

Current Limitations: Restrictions in the blend water system currently lower actual

treatment capacity to approximately 1.4 MGD.

3. PROPOSED SCOPE OF WORK

The City intends to increase finished water capacity to 2.7 MGD and modernize aging

components. While the City has a preliminary framework, the City is open to all

innovative design alternatives that meet capacity, regulatory, and budgetary

requirements.

The anticipated improvements include, but are not limited to:

• Filtration: Replacement of existing gravity filters with high-capacity pressure

filters (approx. 1,200 GPM each).

• RO Expansion: Addition of a third RO skid within a proposed 2,000 sq. ft.

building expansion.

• System Retrofits: Retrofitting pressure pumps and replacing all instrumentation

on existing skids.

• Piping & Blending: Modification to provide finished water hardness up to 160

mg/l without capacity loss.

• Infrastructure: Increasing well capacity, replacing/adding high-service pumps,

and installing a dedicated concentrate pump station and force main.

• Conceptual Schematic

Deliverables Required:

• Topographic Survey & Site Analysis.

• Full Design Engineering (Mechanical, Civil, Electrical, Structural).

• EGLE Part 399 Permitting Support.

• Biddable Construction Document Package.

4. PROCUREMENT BOUNDARIES & COMPLIANCE

To ensure a fair and transparent procurement process, the following boundaries apply:

• No Construction Work: The Consultant shall not perform construction work,

shall not provide construction labor/materials/equipment as a contractor, and

shall not act as a construction manager at risk or design-builder. Construction of

the WTP expansion will be procured separately.

• Bidding Services: Bidding-phase services are limited to preparing bid

documents, responding to bidder questions in writing, and issuing addenda as

authorized by the City. The City will conduct the construction procurement and

award decision in accordance with City policy.

• Funding: This project is currently self-funded by the City (estimated cost $7M).

However, all design work must remain eligible for future State Revolving Fund

(SRF) or federal grant requirements.
