For increased collaboration and project efficiency, Boh Bros. offers Design-Build Construction Services and CMAR Services to both private and public entities. 

Alternative Delivery methods such as Design-Build (DB) and Construction Manager at Risk (CMAR) allow owners, designers, and contractors to work collaboratively on designing and constructing projects. The increased collaboration provides greater efficiency and transparency throughout the project. Boh Bros. has successfully completed DB and CMAR projects and our experience and capabilities make us the ideal alternative delivery contractor.  


Design-Build combines into a single contract the design and construction of a project. Contractors are afforded the opportunity to participate in the design in an effort to reduce cost and contract time. Typically, DB allows delivery of a project more quickly compared to the traditional design-bid-build delivery method.  

Additionally, when projects are more complex – the complexity of a bridge structure or site conditions/constraints – the DB method provides the opportunity for project innovation and creativity. The contractor and designer work together to create an optimal design to reduce costs and impacts on surrounding areas as well as increase the efficiency, quality, and safety of the project. 


As projects become increasingly difficult to manage in time and scope, and public agencies continue to optimize their budgets, the benefits gained through Construction Management at Risk (CMAR) are becoming hard to ignore.  

CMAR is an integrated team approach to planning, design, and construction of a project, starting with a “One Project Team” approach early in the design process.  CMAR enables the project team to achieve schedule and budget certainty, clear risk allocation, complete stakeholder outreach, and integration, as well as ensure safety and quality at the highest level. 

Boh Bros. has played a significant role in promoting the delivery method, as we found the CMAR approach to be a natural fit with our Company’s history of working collaboratively with owners and design professionals. Helping our clients add value to the preconstruction process has been a long-standing tradition at Boh Bros., simply because we love what we do.
