Dam projects have involved major concrete repair and modifications below and above the water surface.
C&W has been involved with dam construction refurbishment, maintenance and repairs. Completed contracts include: the fabrication and installation of stop logs and guides; cleaning, repair and installation of trash racks and screens; and installation, repair and replacement of dam piping and valves.

In addition to underwater construction and repair, C&W has completed upgrades on several major water works located inside of dams that required working in confined spaces and utilized advanced rigging.

C&W’s heavy civil underwater construction projects include earthquake retrofitting of the subsurface foundations on the San Mateo Bridge in San Francisco Bay. Retrofitting operations included concrete core drilling, diamond wire sawing cutting, pier foundation enclosure by fitting and installation of steel jackets, and underwater concrete placement. The 1-1/2 year San Mateo project demonstrates the company's ability to work with customers to identify project problem areas before excess time and money are spent.

C&W has the trained personnel, equipment and experience to perform new installation, repairs and refurbishment on all types of heavy civil projects, including power plants, outfalls, pier installations, canals and pipelines.

The extensive field experience C&W has in engineering facilitates careful planning during the design and development stages of projects and results in savings of time and money.
