Industry Event Notification & Invitation
Potomac Interceptor Rehabilitation Master Services Agreement (MSA)
Contract No.: 260040
RFI DCW-SOL-26-10575
(Washington, DC)

Owner: DC Water

The District of Columbia Water and Sewer Authority (DC Water) is preparing to launch a new acquisition for the Potomac Interceptor (PI) under the terms of a Master Services Agreement (MSA). This initiative underscores DC Water’s commitment to delivering critical infrastructure projects through strong, collaborative partnerships with the industry.

Based on feedback from prior and ongoing market engagement, DC Water has elected to pursue an MSA for this effort with the intent to execute projects as tasks utilizing the construction management at-risk (CMAR) delivery method. This approach is intended to promote early collaboration, cost certainty, and shared accountability throughout project delivery.

DC Water welcomes and encourages all interested and qualified firms to attend the upcoming Industry Outreach Event. This session will provide an overview of the anticipated acquisition, project objectives, and procurement approach, and will offer an opportunity to ask questions and engage with the project team.

Participation in this event will help prospective bidders better understand the scope, expectations, and opportunities associated with the PI program. We look forward to connecting with industry partners and fostering early engagement to support a competitive and informed solicitation process.

The scope includes rehabilitation and construction of large-diameter sanitary sewer infrastructure, focused on interceptors and tunnels ranging from 30” to 96” in diameter. Work will require designing, setting up, and operating high-capacity bypass pumping systems (40–150 mgd) over distances exceeding one mile, supported by the construction of temporary access chambers for pumping and rehabilitation activities. Permanent concrete access chambers will also be constructed to support current work and future inspection, maintenance, and repairs. Pipeline rehabilitation may use geopolymer lining, cured-in-place pipe (CIPP), slip lining, spiral wound lining, or other appropriate large-diameter technologies, depending on pipe type and existing conditions. The scope also includes new sewer pipeline construction across the Potomac River, using open-cut or tunneling methods to create an inverted siphon. Additional work involves pipeline armoring at culvert and stream crossings, construction and removal of temporary access roads in environmentally sensitive and steep areas, and tree and vegetation removal with full restoration upon project completion. DC Water anticipates an upper program limit of $500 million.

Request for Supplier Qualifications for Preconstruction and Construction Services
Integrated Pumping Station Construction Contract 3 (IPS CC3)
(Toronto, Ontario, Canada)

Owner: City of Toronto

The City of Toronto is preparing to issue a request for supplier qualifications (“RFSQ”) to obtain a statement of qualification from proponents interested in providing preconstruction and construction services for the Integrated Pumping Station Construction Contract 3 (IPS CC3) using the construction management at-risk (CMAR) method of project delivery. The project is located at the Ashbridges Bay Wastewater Treatment Plant. The remaining scope of the IPS CC3 project will be delivered under the CMAR model (referred to as IPS CC3 AD), which is the subject of this RFSQ. It is estimated that the IPS CC3AD project construction phase will be 10 years, with a two-year post-construction period. The Integrated Pumping Station (IPS) is intended to replace the existing aging M&T Pumping Stations and to manage dry weather and wet weather flows in sewershed.

The City of Toronto will be conducting information sessions ahead of the posting of this RFSQ, which prospective suppliers are encouraged to attend in order to gain a better understanding of the scope requirements and project details. The sessions will be held virtually on the following dates and times:

• Monday, May 25, 2026, from 2 pm to 4 pm
• Tuesday, May 26, 2026, from 10 am to 12 pm

Suppliers will be allowed to submit questions in advance (and after the sessions) to Ryan Phelan (ryan.phelan@toronto.ca). These may be addressed during the information sessions, otherwise all questions (before, during, and after) will be responded to in writing and posted on this NOIP for review. If you are interested in attending a session, please share the names and emails of the attendees and the session you plan on joining with Ryan Phelan (ryan.phelan@toronto.ca).

A Teams meeting link will be provided shortly ahead of the meeting dates. A full presentation deck will be provided ahead of the meetings as well, which will be part of the information session presentations.

Request for Proposals
Research Project: Environmental and Financial Drivers of Collaborative Delivery Adoption in the Water Sector
(Project involves participation in virtual/in-person meetings/presentations, locations TBD)

Client: Water Collaborative Delivery Association

WCDA is issuing this RFP to identify and obtain data throughout the water utility market sector in order to evaluate the environmental and financial drivers of collaborative delivery adoption. For purposes of this proposal, “water” refers to all water, wastewater, treatment, distribution, conveyance, and reuse systems and services.

Water utilities across the United States are investing significant capital in infrastructure upgrades and expansion while facing increasing challenges related to funding constraints, regulatory requirements, workforce limitations, contractor market capacity, and supply chain volatility. Project delivery approaches that involve early collaboration among owners, designers, and constructors are increasingly used to address these challenges. However, adoption varies significantly across utilities and regions. Utilities must also manage significant uncertainty when planning and delivering infrastructure projects. These uncertainties may include cost escalation, regulatory compliance requirements, schedule pressures, technology implementation challenges, and contractor market capacity. CD approaches are often used to address these uncertainties by enabling earlier coordination among project participants and earlier identification of potential risks.

This research will examine the environmental, financial, organizational, and market conditions associated with the adoption of collaborative delivery, including how collaborative approaches may support risk management across the project life cycle.

Research Objectives
The objective of this research is to identify patterns and trends associated with the adoption of collaborative delivery in Water infrastructure projects.

Key research questions include:
1. What environmental and organizational conditions lead utilities to adopt collaborative delivery?
2. How do funding structures and capital planning processes influence delivery method selection?
3. What project, market, and organizational conditions correlate with successful collaborative delivery outcomes?
4. How do project complexity and regulatory drivers influence delivery decisions?

The research will also examine whether collaborative delivery approaches are more frequently adopted in situations where utilities face elevated financial, regulatory, technical, or market risks.
