Control building included computer floors, large IT & security rooms, and 3 different fire protection systems (wet, dry & FM-2000 to protect the data command center). Site work included new masonry walls, 12,650 sq. ft. parking area, new generator, and new sliding gate.
Project consisted of the installation of 1,100 Kilowatts peak Sunpower Solar Electric (Photovoltaic) System consisting of 3,200 modules in the form of rooftop solar, elevated carport arrays, and associated electrical equipment.
The SunPower Sweetwater project consisted of the installation of 2 MW of photovoltaic panels at seven different public schools within the Sweetwater School District. Perera managed the construction of a ground-mount, fixed-tilt PV system; multiple carports and shade-structures; as well as rooftop mounted solar systems. These projects were completed within two-months of receiving DSA permits.
Project consisted of new construction with heavy mechanical and electrical systems with associated site work and parking. Also included off-site & on-site sewer pump station, off-site sewer and water. All metal was grounded to copper grounding grid, electrical grid reconditioning, capable of redirecting energy to other substations in the event of a power failure.
Project consisted of ground-up, 14,500 sq. ft., two-story administration building with 20 rooms. Class II Road base, and paving was approximately 42,000 sq. ft. and was to accommodate all roadways, parking areas, and drainage requirements for the new administration building. New 300 gallon septic system was also installed.
Project consisted of the complete renovation of 120,000 sq. ft. building to include multiple office renovations/additions, new cubicle installation/remodel, conference room remodel, small kitchen/break room remodel, and multipurpose room remodel. Also included, HVAC, electrical, and mechanical upgrades.
The Rialto I-210 project consisted of installing 10,920 rooftop solar panels and equipment as well as interconnecting them into SCE electrical grid for a total of 2.6 MW DC. Work included installing Trina modules, Sunlink Racking, wiring to combiner boxes, wiring of DC power to Satcon inverters at various enclosure locations, wiring 12 KV AC power to switch gear and transformer for distribution back to SCE’s power grid. Work also involved constructing three equipment enclosures to house all the various components. Masonry enclosure was plastered with reveals to match existing building. EIFS conduit chase were also constructed to conceal conduit runs.
Projects consisted of the installation of rooftop mounted solar panels and equipment as well as interconnecting them into SCE electrical grid. Work included installing Sunpower modules, wiring to combiner boxes, wiring of DC power to inverters at various enclosure locations, and wiring 12 KV AC power to switch gear and transformer for distribution back to SCE’s power grid. Work also involved constructing multiple equipment enclosures to house all the various components. Masonry enclosure was plastered with reveals to match existing building. EIFS conduit chase were also constructed.
The RDC 2 project consisted of (5,928) 2 MW panels, the RDC 4 project consisted of (15,680) of 5 MW panels, and the RDC 5 project consisted of (15,900) of 5 MW panels.
Dexus is one of, if not the largest, single-roof mounted solar installations in the world. Perera Construction installed 33,280 Sunpower modules equating to 10.15 MW AC power output as well as all of the supporting equipment necessary to interconnect the installation to Southern California Edison’s power grid.
Work included installing Sunpower modules, wiring to combiner boxes, wiring (over 75 miles) of DC power to inverters at various enclosure locations, and wiring 12 KV AC power to switchgear and transformer for distribution back to SCE’s power grid. Roof square footage was 1,686,590 sq. ft. (which equates to 38.7 acres). This area would facilitate the installation of 29.3 football fields, including the end zones. Work also involved constructing three equipment enclosures to house all the various electrical components. Masonry enclosure was plastered with reveals to match existing building. EIFS conduit chase were also constructed.
Project consisted of 25,000 sq. ft. ground-up metal building, to house offices, break room, cubicle space, storage/filing room, and parking lot. Project is certified LEED Silver. Also included Sewer pump station, off site sewer and water, decorative color concrete, metal shade canopies. All metal was grounded to copper grounding grid.
Project consisted of complex seismic reconstruction of existing structure including attached ground-up construction. Project includes seismic retrofit of a multi-story existing structure, AC/DC electronics, moisture barrier protection, 12,000 gallon underground fuel tank for attached emergency back up generator, over 120 caissons poured in place up to 40 and 60 feet in depth for new footings, complex seismic bracing. Due to highly sensitive existing telecommunications electronics, complex HVAC system was maintained during construction, dust control was maintained during construction, and utilities could not be disturbed. Interior includes administrative offices, clean room environment, complex seismic bracing, complex utilities, and disruption phasing.
