Designed by the Rhode Island-based architectural firm of Robinson Green Beretta (RGB) and Boston-headquartered Architectural Engineers, Inc (AEI), the new $34 million transit operations facility in Providence, RI began construction in 2008 and was completed in 2010.
Intended to consolidate operations previously spread out in several buildings, the overall RIPTA design and build objective was to create a facility to house RIPTA operations for at least the next 80 years, said John Racine, RGB's project architect. In addition to housing administrative offices, the 140,000 sq. ft. building provides space for total bus maintenance tasks, now to be conducted under one roof.
The result of the two-year plus construction project is a state-of-the-art building in terms of maintenance, electronics, and security, and one that reflects the traditional look of New England architecture. Examples of the facility's high design include a white membrane roof to effectively dissipate heat build-up; moisture barriers that provide as much drainage as possible; the largest installation of heavy-duty street pavers in New England; a parking deck on the roof, also unusual for New England architecture; and high efficiency lighting systems both inside and outside the building.
Extensive tests of light fixtures employing metal halide, fluorescent and LED light sources were conducted prior to final luminaire selection, according to David Walkenstein, a senior electrical engineer at AEI who developed the electrical plan, including the lighting design. The exhaustive tests covered life-cycle studies, distribution patterns and overall costs, he said.
With studies completed and evaluated, eight of the 21 iconic brands manufactured by Hubbell Lighting were chosen to illuminate the new RIPTA building. Architectural Area Lighting's Providence series (the name is coincidental to the project location) with decorative cast bases make up most of the roof parking deck and site lighting. Hubbell Outdoor flood lights and Spaulding Laredo wall packs are employed around the building perimeter. Spaulding Cimarron rectilinear fixtures and Hubbell Industrial class 1 explosion-proof fixtures are used at the fueling station. Topping off the site, Kim Lighting in-grade fixtures illuminate the flag and flagpole.
The areas inside the building are divided into bus parking/storage, maintenance garage, wash bays, fueling, and administration, and feature 4 and 6- lamp T8 fluorescent industrial high bay lighting fixtures from Columbia Lighting. Considering life-cycle costs, including initial cost, power consumption and periodic maintenance for 300 fixtures, plus about 30+ UL wet location luminaries in the wash bays, these were the best solution noted Walkenstein.
The interior corridors are lit with Prescolite low brightness compact fluorescent down lights, and administration offices use Columbia Lighting's Stratus Series indirect/direct center basket light fixtures. Back of the house areas, file copy rooms, and maintenance closets and storage are lit with 100+ of Columbia Lighting's corridor and shallow wrap around fluorescent fixtures.
Completing the lighting of RIPTA's new home, Walkenstein integrated life safety egress path lighting into Prescolite down lights using Dual-Lite integral emergency battery backup and supplemented with Dual-Lite explosion-proof units in hazardous storage areas.
