River Mountains Water Treatment Plant

Clark/Sullivan constructed this state-of-the-art water treatment facility for the Southern Nevada Water Authority through a design-bid-build delivery system. The building is constructed of concrete masonry units and a large variety of architectural elements such as metal panels, aluminum sun shades, screening and fins which add to the energy efficiency and enhance the design.nnThe laboratory itself contains a labyrinth of piping and drainage systems, with refrigeration and processing stations designed to monitor the water quality for distribution to the community. This complex laboratory is built into the side of a mountain requiring tie back systems and extensive poured in place concrete structures.nnThe River Mountain Water Treatment Lab is a perfect example of Clark/Sullivan’s ability to construct a complex building through a public bid system on-time and without change orders.n n

Delivery Methods

The greatest opportunities for innovation, quality, responsive scope and competitive pricing result when owners, users, designers, contractors and subcontractors all collaborate on one team. Collaboration can be found in all of our delivery methods.


By providing a single point of responsibility, C/S collaborates with all on the team to deliver quality, innovation, timely construction and the best possible value.


As a team contributor during pre-construction, C/S optimizes constructability, provides pricing alternatives, scheduling insights, logistics and more to enhance value.

Construction Management At Risk (CMAR)

We successfully manage the design, budget and schedule from preconstruction through final completion, turning conceptual plans into a complete and fully operational building that exceeds expectations while working within a guaranteed maximum price.


This creative contractual agreement is similar to CMAR. C/S provides both pre-construction and construction services with flexibility, financing options, and a single point of responsibility. We can provide exceptional value and timeliness working within strict design requirements and regulations.


While we don’t get to weigh in on this traditional delivery method, we still work collaboratively to ensure the team stays true to the project vision by facilitating partnering meetings. We also look for ways to add value to the project by working closely with subcontractors in quality control. The common thread running through the first four delivery methods is pre-construction services.
