The timely completion of each of 17 construction contracts was critical to the overall success of the total expansion project.

Carollo, in joint venture, provided construction administration and inspection services for the $145 million Southern Nevada Water System Improvements Project. This project (which is described in detail elsewhere in this SOQ) includes: expansion of the existing Alfred Merritt Smith (AMS) Water Treatment Plant to 624 mgd, a 12-foot-diameter tunnel, a new water reservoir, and additional pipelines and pump stations.

The joint venture team was also responsible for design of the world's largest ozone generation system. With a construction cost in excess of $60 million, the AMS system provides preozonation in advance of flocculation and filtration.

Carollo took the lead in providing construction administration services. The team managed 17 separate construction contracts and three prepurchase contracts on a tight schedule to meet the increasing water demands of the rapidly growing Las Vegas metropolitan area. The timely completion of each construction project was critical to the overall success of the total expansion project. Work included construction activities in three separate work areas and coordinating the construction around the treatment plant’s operations to ensure a consistent and reliable water supply for Southern Nevada Water System’s customers. Another firm provided program management for the projects.

The team provided well coordinated, integrated, and scheduled services under the direction of Carollo’s manager. Construction began in 1995 and was completed in 1997. The team provided a full-time construction coordinator, three resident engineers, three assistant resident engineers, and 14 construction inspectors. Services included field inspection; resident engineering; shop drawing and RFI review/response; partial payment request processing; change order review, negotiation, and recommendations; and claims management.
