ECI – Early Contractor Involvement

Why Engage a Builder Early? Many start their projects by going straight to an architect or consultant, only to find out later that their design exceeds their budget. This leads to costly redesigns, delays, and compromises. By involving a builder early in the process, you get:

  •  Cost-effective design insights – Ensure your vision aligns with your budget from the start.
  • Practical construction knowledge – Avoid designs that are expensive or impractical to build.
  • Fewer surprises – Minimize costly changes and delays later in the project.
Example

How Late Builder Involvement Leads to Cost Blowouts A client plans to build their dream home with a budget of $500,000. Excited to start, they hired an architect to design a modern, spacious house with high-end finishes, large windows, and complex structural features. 

However, there’s no discussion about construction costs during the design phase. Once the design is finalized, the client approaches a builder for pricing. The quote comes back at $800,000—$300,000 over budget. 

Now, the client is forced to: Redesign the home, adding time and extra design fees. Scale down the build, losing key features they originally wanted. Stretch their budget, taking on unexpected financial pressure. 

Engaging a Builder Early Had the client involved a builder from the beginning, they would have received realistic cost guidance throughout the design process. The builder could have suggested

  • Alternative materials that achieve the same look at a lower cost. 
  •  More efficient design choices to reduce unnecessary complexity. 
  • Practical construction methods to keep the project within budget. This approach ensures that when the plans are finalized, the home is designed to be built within the client’s budget—without major compromises.
