Johnston Construction Company
- Performed the major civil and site-development package supporting construction of a new 300,000-gallon elevated water storage facility for the Town of Chesapeake City. JCC’s contracted work included tank foundation construction, underground piping, site development, erosion and sediment controls, paving, stormwater improvements, exterior vault work and associated civil infrastructure.
- Constructed the foundation infrastructure supporting the new elevated water storage tank, which was designed for a minimum operating capacity of 300,000 gallons and a height of approximately 113 feet from the top of foundation to the high-water level. JCC’s subcontract specifically included tank foundation work in accordance with CB&I foundation drawings.
- Coordinated foundation construction with the piling subcontractor and tank erection operations, including site layout, support of piling activities and setting of anchor bolts furnished by CB&I. JCC also prepared dedicated stone working areas around the foundation to accommodate CB&I’s crane operations during tank construction.
- Completed the underground water-system improvements connecting the new tank to the Town’s existing distribution system. The overall project included approximately 1,225 linear feet of 8-inch water main and fittings, while JCC’s subcontract specifically included piping shown on the civil drawings, including 8-inch ductile iron piping extending to the tank riser connection.
- Constructed the exterior valve-vault and associated civil piping infrastructure required to integrate the new elevated storage tank with the municipal water system. The work required close coordination between the underground piping, tank foundation and subsequent tank-system connections.
Concrete Services Division
- Performed the concrete construction package for the foundation of the Town of Chesapeake City’s new 300,000-gallon elevated water storage tank. CSD’s subcontract specifically included forming and concrete-placement labor for the tank foundation, interior tank floor slab and overflow splash pad, supporting the larger elevated-tank construction program.
- Constructed the curved-wall concrete portion of the elevated-tank foundation, including approximately 476.47 square feet of curved-wall formwork and placement of approximately 48.53 cubic yards of wall concrete. This work required accurate form construction and placement in coordination with CB&I’s tank-foundation drawings and the geometry of the future elevated structure.
- Performed concrete work for the interior tank floor slab, including slab-on-grade forming and approximately 3.80 cubic yards of slab concrete placement, providing the interior concrete surface within the completed foundation system.
- Completed multiple concrete-finishing operations across the tank foundation, including approximately 380.37 square feet of float-and-screed finishing and approximately 205.27 square feet of machine-trowel finishing. These operations were coordinated with placement activities to achieve the required finished concrete surfaces.
- Performed detailed post-placement concrete finishing and surface treatment, including approximately 476.47 square feet of pointing and patching and approximately 34.03 square feet of bag finishing, supporting a clean and complete final foundation appearance.
Electrical Services Division
- Performed the electrical construction package supporting the Town of Chesapeake City’s new 300,000-gallon elevated water storage tank, providing the electrical infrastructure necessary for power, lighting, instrumentation wiring, grounding, surge protection and lightning protection associated with the completed tank facility.
- Furnished and installed conduit, conductors and electrical connections for both power and lighting systems, together with separate conduit, wiring and connections required for the tank’s instrumentation systems. The work supported the overall project requirement for electrical service and local instrumentation and control features at the new elevated storage facility.
- Installed a comprehensive LED lighting system throughout the elevated tank, consisting of 5 interior LED fixtures at the base, 10 interior LED fixtures within the tube and 4 exterior LED floodlights, along with the associated conduit, wiring, switches, receptacles and electrical connections.
- Furnished and installed the electrical service, panelboard and surge-protection equipment serving the new tank facility, together with the panels and gear necessary to distribute electrical power to the tank’s lighting, instrumentation and associated electrical loads.
- Installed the tank grounding system in accordance with the project grounding diagram and completed the lightning-protection system, providing the electrical bonding, grounding and lightning-protection infrastructure required for the elevated steel structure.
