Laurel 500,000-Gallon Elevated Water Storage Tank – Foundation & Infrastructure Construction

Key Accomplishments

• Constructed the concrete foundation supporting the elevated steel water storage tank, including foundation excavation, installation of CB&I-supplied anchor bolts, concrete placement, foundation backfilling, and associated inspection and testing requirements.
• Installed the concrete floor within the base of the tank structure, together with associated concrete pads, site drainage improvements, and foundation restoration activities.
• Furnished and installed underground water piping, valves, fittings, supports, and thrust blocks, including connections to existing 16-inch and 8-inch water mains through expansion joints furnished by CB&I.
• Completed installation of the tank's overflow bypass piping, including a 6-inch gate valve, overflow riprap, and associated tank drainage infrastructure.
• JCC's mechanical construction scope included equipment installations, piping connections, and associated components required to support the operation of the elevated water storage facility.
• Furnished and installed spray-foam insulation and an ignition-barrier coating along the interior of the tank's fluted support column and beneath the steel condensate ceiling.
• Performed electrical and instrumentation work associated with the water storage facility, including installation of electrical components, general instrumentation, a free-chlorine analyzer, and the tank mixer control panel and associated wiring.
• Provided construction activities associated with altitude valve vaults at Tank No. 1 and Tank No. 2 locations, supporting the operation and control of the municipal water distribution infrastructure.
• Coordinated geotechnical inspections, concrete testing, underground piping installation, pipe disinfection, and preparation of construction documentation in accordance with the project requirements.
• Additional infrastructure work included construction activities associated with altitude valve vaults at Tank No. 1 and Tank No. 2 locations. Johnston Construction Company's contract required furnishing and installing the vault facilities and associated components necessary to support the water storage system's operating requirements. The work involved coordination of underground piping, mechanical installations, and the facility's water distribution connections.
• The Project Was Completed On June 30, 2015.
