Johnston Construction Company
- Performed the major civil construction package supporting Pennsylvania-American Water Company’s new 0.75-million-gallon Franklin-Malone welded steel water storage tank and associated rechloramination facilities. The overall project incorporated the new storage tank and foundation, site development, water-main improvements, stormwater controls, rechloramination facilities, utilities, electrical and instrumentation systems, fencing, paving, and final site restoration.
- Completed substantial tank-foundation and site-development work, including surveying and layout, erosion and sediment controls, clearing and grading, construction of the spread-footing tank foundation, foundation conduits for tank systems and antennas, a 6-inch concrete floor slab, interior concrete floor and pipe supports, hoist-deadman preparation, and grading to provide positive drainage away from the completed tank foundation.
- Installed the major water-main and process-piping infrastructure serving the new storage facility. JCC’s subcontract included piping, valves, fittings, hydrants, supports, and thrust blocks from the limits of the existing 16-inch waterline at South Hewitt Avenue to the new tank connections. Contract pricing also incorporated approximately 250 LF of 12-inch water main, 20 LF of 8-inch water main, and one 12-inch magnetic flow meter.
- Constructed the foundation and under-slab piping for the prefabricated rechloramination station and coordinated installation of the Owner-furnished treatment station. JCC’s contractual package also incorporated chemical-injection lines, water-analyzer lines, ductile-iron piping taps, drainage, and the civil and mechanical interfaces necessary to integrate the rechloramination system with the new storage facility.
- Completed the principal site drainage and access improvements, including drain lines and drain manholes, approximately 150 LF of SDR-35 PVC drain line, 150 LF of HDPE drain line, approximately 12,500 SF of driveway and site pavement, and approximately 430 LF of fencing and gate work, together with bollards, access-road subbase, bituminous paving, and associated site restoration.
Concrete Services Division
- Performed the specialized cast-in-place concrete package supporting Pennsylvania-American Water Company’s new 0.75-million-gallon Franklin-Malone water storage facility. CSD’s work supported the tank foundation, the new rechloramination building and associated concrete structures within a larger project that included the water-storage tank, water mains, treatment equipment, drainage, electrical, instrumentation and SCADA systems.
- Provided the labor, materials, tools and concrete-trade services required for the tank foundation, rechloramination building footings and walls, building slab, tank slab, generator slab and associated concrete work. The subcontract specifically incorporated forming, concrete placement, finishing and curing operations for these structures.
- Placed approximately 210 cubic yards of structural concrete across the contracted tank and building components. The detailed control estimate included approximately 114.38 CY of tank footing concrete, 40.62 CY of tank wall concrete, 11 CY of tank slab-on-grade, 27.23 CY of building wall concrete and 16.65 CY of building slab-on-grade concrete.
- Constructed extensive formwork for both the tank foundation and rechloramination building, including approximately 167 SF of tank-footing forms, 1,097 SF of curved tank-wall forms, 490 SF of straight building-wall forms and 112 SF of building slab-on-grade forming.
- Completed multiple concrete-finishing operations tailored to the different structural surfaces, including float-and-screed finishing, machine troweling, point-and-patch work and bag finishing for both the tank and building concrete. The contracted quantities included more than 1,800 SF of float-and-screed work on tank concrete and substantial wall patching and surface finishing.
Electrical Services Division
- Performed the electrical construction package supporting Pennsylvania-American Water Company’s new 0.75-million-gallon Franklin-Malone Water Storage Tank and associated site facilities. ESD’s subcontract covered electrical systems required for the tank, site infrastructure and related equipment in accordance with the project’s Division 16 specifications and electrical drawings E-1 through E-10.
- Furnished and installed the project’s principal power-distribution infrastructure, including power conduit, conductors, wiring and electrical connections together with the electrical service, panelboard, surge-protection device and switchgear required for the completed facility.
- Installed instrumentation conduit, wiring and electrical connections serving the tank instrumentation and control systems. This work provided the field electrical infrastructure necessary to interface process instrumentation with the overall control and telemetry system serving the completed storage facility.
- Completed the tank and site lighting systems, including fixtures, switches, receptacles, wiring devices and associated raceway and branch-circuit work. The subcontract specifically incorporated the project’s building-lighting and occupancy-sensor specification sections.
- Wired the packaged emergency-generator system furnished by Johnston Construction Company, providing the electrical connections required to integrate standby power into the completed tank facility. ESD’s contract specifically assigned generator-system wiring to ESD while the generator equipment itself was furnished by JCC.
