Partners in Building Outdoor Places
Civil Work • Hardscape • Greenspace

Building a sense of community in cities across Colorado is what we do. Using CM/GC and Design-Build approaches is how we do it.  ECI blends downtown redevelopment, park and sports venue construction, and natural area restoration to create urban environments that stimulate a renewed sense of belonging.

Collaborative Construction Services

Construction Manager / General Contractor

A Colorado CM/GC construction firm, ECI serves as your construction manager, collaborating with you throughout the project. We suggest updates to the finished design that can positively impact project costs, scheduling, materials and efficiency. Constant collaboration throughout the entire project is key.  


Design-Build is the most efficient construction model. ECI brings the most qualified design team to the table, creating one entity that provides design and construction services. One entity, one contract, one unified flow of work from initial concept to completion. Construction occurs simultaneously at each design stage, with constant communication the norm. The result is reduced costs and faster construction of Colorado recreation, civil infrastructure and waterway projects.
