ECI Site Construction Management is the preferred builder of outdoor environments in the northern Colorado and Denver regions. Our collaborative construction expertise includes recreational venues, community parks, complex waterways, streetscapes, and heavy civil projects. By employing CM/GC and Design-Build methods, we complete projects efficiently and collaboratively to ensure optimum results. Our dedicated crew of project managers, engineers, superintendents and field staff are passionate about the work they do, evidenced by the level of detail and precision that goes into every step of the process.

At the end of the day, it’s about the legacy we leave behind.


Our pre-construction services assist clients with project scope development, constructability reviews, value engineering, and preparation of construction costs to determine the most effective route for each project.


As a construction manager, we partner with our clients throughout the entire project and suggest updates to the finished design that can positively impact project costs, scheduling, materials and efficiency.


Our integrated design-build services provide our clients with a single-source of responsibility for quality control, schedule, and budget adherence, which allows us to react quickly to design and construction challenges.
