Delivery Systems

Design/Build is a construction project delivery system that helps us manage our project team from start to finish. The Design/Build system offers transparency for architects, engineers, and consultants. The result is substantial time savings for the owner.

Design Build

  • Enhanced Efficiency
  • Streamlined Communication and Centralized Management
  • Value-Based

Building the way buildings want to be built

Colas Construction often generates increased value for Owners, while maintaining budgets and a robust timeline when utilizing a Design/Build approach for our projects in collaboration with premier architectural firms. 


Construction Manager / General Contractor

The Construction Manager/General Contractor (CM/GC) augments the General Contractor’s traditional work scope with that of a Construction Manager. Under a single contract with the Owner early in the design phase, the CM/GC allows the General Contractor to collaborate with the Architect and Engineer on design development and preparation of design documents prior to finalizing budgets and beginning construction. Utilizing this approach, Colas Construction has reduced project time and created significant cost savings for Clients.


  • Collaborative Team Approach
  • Efficient Constructability
  • Targeted Goals

General Contractor

The General Contractor (GC) is responsible for the means and methods of executing the project. GCs select Subcontractors and manage the project with continuous documentation to ensure efficiency and provide expertise throughout the building process.

In addition to established relationships with reputable local and regional Subcontractors, Colas Construction increases value by self-performing multiple aspects of the project at the Client’s request. As shown in our portfolio, our Project Team continues to demonstrate outstanding value and service spanning for a wide variety of complex and difficult project types. With every project, we look forward to raising the standard in building practices that are sustainable, cost-effective, and meaningful to the community.

  • Experienced Estimators maximize the budget to elevate project value
  • Skilled Project Managers understand how to procure and build high-performance Project Teams
  • Proficient Superintendents construct projects according to the plans, time, and budget

Integrated Project Delivery (IPD)

IPD integrates all partners from the beginning of the design and construction process to the end. Designers, Builders, and Ownership share a common goal of maximizing productivity and eliminating wasteful process methods to focus on value delivery. The IPD system holds members of the Project Team accountable.

  • Decreases Wasteful Needs
  • Enhances Accountability
  • Generates Good Faith

Colas Construction uses IPD to generate budgets and to keep Contractors, Designers, and Ownership partners well-informed.
