Collaborative delivery methods—such as design-build, progressive design-build, and construction management at-risk—are transforming how water and wastewater projects are delivered. While each model differs in structure, they all rely on one fundamental principle: clear, consistent, and inclusive communication among all project participants.
Effective collaboration goes beyond contracts and delivery models. It requires early alignment and ongoing dialogue between owners, engineers, contractors, suppliers, and other stakeholders. When communication is intentional and transparent, teams are better equipped to manage risk, control costs, and deliver long-term value.
Moving Beyond Traditional Silos
Traditional project delivery often places stakeholders in isolated roles—engineers design, contractors build, and suppliers respond after key decisions are made. This approach can limit innovation and increase the likelihood of schedule delays, cost overruns, and constructability issues. With isolated roles and separated contracts, everyone operates within their own internal echo chamber, using what each entity considers to be the best method. Engineers do not talk with suppliers to understand the latest products and materials but instead use what they know from previous jobs. Speaking with one engineer, they used the same product spec for over 15 years before working on a collaborative delivery project where they were informed that product had been discontinued for over a decade. General contractors look at plans and identify issues through change order requests, expanding construction timelines and costs. Suppliers are not brought into the conversation until materials are needed, often leading to delayed timelines due to long lead times or rush orders that drive costs up.
Collaborative delivery breaks down these silos by encouraging open communication early in the process. Engaging all team members from the outset allows potential challenges to be identified and addressed before they impact the project. Risks become minimized and design obstacles are discussed in the preconstruction phase where change is easiest to make and least costly to the overall project.
The Importance of Early Supplier Involvement
Suppliers play a critical role in project success, yet their expertise is often brought in too late. Early communication with suppliers provides valuable insight into availability, lead times, material options, and life cycle costs. In today’s environment of extended manufacturing timelines and supply chain uncertainty, this information, and staying up to date on it, is more important than ever. A material quote is only part of the story; you are not getting inventory information, lead-time history data, and, most importantly, performance at meeting project timelines.
When suppliers are engaged and part of the conversation early, teams can make informed decisions that align design intent with real-world constraints and supply chain pinch points, reducing risk and improving schedule reliability.
Strengthening Alignment Between Engineers and Contractors
Successful collaborative projects depend on strong alignment between engineers and design-builders. Engineers bring technical expertise, regulatory knowledge, and performance criteria, while design-builders contribute construction experience, cost-control strategies, and risk management.
Open communication and regular coordination help ensure that innovation enhances project outcomes without compromising quality, operability, or long-term performance. A shared understanding of goals and constraints fosters a true “one team” mindset.
Owners Set the Tone
Project owners benefit the most from effective communication. Teams that collaborate openly deliver fewer change orders, greater cost certainty, and improved schedule performance. Owners, including owner advisors, who encourage early engagement and inclusive communication create an environment where challenges are solved collectively, not reactively. Project constraints and end-user goals are set, and through continued conversations between the owner and the project team, designs come together to maximize project outcomes, minimize scope creep, and increase operational productivity.
Communication as a Project Tool
In collaborative delivery, communication is not a soft skill—it is a critical project tool. Clear expectations, frequent dialogue, and mutual respect enable teams to make better decisions, adapt to changing conditions, and deliver infrastructure that meets both immediate and long-term community needs.
To have successful communication, and thus collaboration on a project, all relevant parties must be brought to the table early. Engineers, contractors, and critical suppliers must be viewed as one project team with the shared responsibility of guaranteeing project success. Owners must clearly define the project objectives and available funding and then allow this unified project team the ability to be creative in their design, construction approach, and material selection.
WCDA’s Role
The Water Collaborative Delivery Association (WCDA) continues to promote best practices that strengthen collaboration across the water sector. By emphasizing the importance of communication among all project participants—including suppliers—WCDA supports more resilient, efficient, and successful project delivery.
