Is CMAR the Same as Design-Build?
When diving into the world of construction project delivery methods, terms like CMAR and Design-Build frequently arise. But what do they mean? Are they interchangeable? Let’s dissect these concepts to understand their similarities and differences and which might be the best fit for your next project.

What is CMAR?
CMAR stands for Construction Manager at Risk. In this method, the owner receives advice from the construction manager during the development and design stages. Later, they become the general contractor during the construction phase, taking on the risk of delivering the project on a guaranteed maximum price (GMP).
The Role of the Construction Manager
In CMAR, the construction manager’s role evolves over the project’s lifecycle. Initially, they provide input on the design to ensure cost-effectiveness and constructability. As the project transitions to construction, they assume responsibility for completing the project within the GMP, absorbing any costs exceeding this amount unless changes in scope occur.
Benefits of CMAR
- Early Involvement: CMAR allows the construction manager to be involved early in the design process, leading to better collaboration and informed decisions.
- Cost Control: The GMP offers a clear budget limit, providing financial security for the project owner.
- Risk Mitigation: The construction manager assumes significant risk, protecting the owner from budget overruns.
What is Design-Build?
With the design-build project delivery technique, a single team is responsible for design and construction services, working under a single contract. This contrasts with the traditional approach, where design and construction are separate contracts.
The Unified Team Approach
In Design-Build, a unified team works together from the project’s inception. This team usually consists of designers, engineers, and builders who collaborate to deliver the project efficiently.
Benefits of Design-Build
- Single Point of Responsibility: With one entity responsible for design and construction, communication is streamlined, reducing the chances of misunderstandings and conflicts.
- Faster Delivery: Design and construction phases can overlap, accelerating project timelines.
- Cost Savings: A unified team can optimize the design and construction process, leading to potential cost savings.
Choosing Between CMAR and Design-Build
The choice between CMAR and Design-Build often depends on the project’s specifics:
- Complexity: For complex projects requiring extensive coordination, CMAR might be more suitable due to early involvement and collaborative decision-making.
- Speed: If the project timeline is tight, Design-Build can offer faster delivery through concurrent design and construction phases.
- Control: Owners who prefer to retain more control over the design process might lean towards CMAR, while those comfortable with a more integrated approach might opt for Design-Build.
Owner’s Preference
The owner’s experience and comfort level with risk and control also play a significant role in deciding the best delivery method. Those familiar with construction projects and looking for a hands-on approach might prefer CMAR. In contrast, owners seeking a streamlined process with less involvement might favor Design-Build.
Integrating Technology in CMAR and Design-Build
Both CMAR and Design-Build benefit from integrating technology like BIM. BIM facilitates collaboration, enhances design accuracy, and improves project visualization, leading to better decision-making and efficiency.
Project Management Software
Utilizing advanced project management software can streamline processes, improve communication, and ensure timely delivery in both CMAR and Design-Build projects.
Future Trends in Project Delivery
With an increasing emphasis on sustainability, both CMAR and Design-Build are adapting to include green building practices. This trend is likely to grow as environmental concerns continue to influence construction practices.
Innovative Contracting Methods
New hybrid models combining elements of CMAR and Design-Build are emerging, offering tailored solutions to meet the unique needs of different projects. These innovative approaches aim to harness the strengths of both methods while mitigating their weaknesses.
FAQs
The main difference lies in the contract structure and risk allocation. CMAR involves separate contracts for design and construction with the construction manager at risk, while Design-Build assumes all risks and unites design and construction under a single contract with the design-build team.
Design-Build is typically faster because the design and construction phases can overlap, allowing for a more streamlined process.
Yes, both methods can be applied to a variety of projects, but the choice depends on factors like project complexity, timeline, and the owner’s preference for control and risk management.
While the design-build team has more control, a well-chosen team will ensure the owner’s vision is realized. Collaboration and communication are essential to preserving the owner’s power.
Yes, innovative contracting methods are emerging that combine elements of both CMAR and Design-Build, offering customized solutions to meet the particular needs of various projects.
Conclusion
In conclusion, CMAR and Design-Build are distinct yet powerful project delivery methods. CMAR offers early involvement and cost control with a guaranteed maximum price, while Design-Build provides a unified team approach for faster, more streamlined project delivery. The choice between them hinges on the project’s complexity, timeline, and the owner’s preference for control and risk. By understanding these methods’ nuances, project owners can make informed decisions to ensure their projects’ success.
