North Smithfield Middle School
RGB, in collaboration with Gilbane Building Company, conducted an in-depth evaluation of several North Smithfield public schools. As a result of the evaluation, a master plan recommendation, in a three-phased approach, was made to design a new middle school, a new elementary school, and upgrade and expand the high school. The proposed new middle school received bond approval by the Town of North Smithfield in April 2006.
The project included the upgrading and expanding of the existing High School parking lot as well as new parking for the Middle School. Approximately 400 sparing spaces were created with 90 additional spaces during construction.
A new public well was drilled to supply additional water to the site. The old constant speed duplex domestic booster system was upgraded to a new state of art variable speed quadruplex domestic water booster pumps and control system. Over 1,700 feet of 2” PVC and 1,300 feet of ductile iron pipe were installed for the domestic water distribution system. On the fire protection system, over 1,900 feet of 8” ductile iron pipe was provided.
Part of the stormwater treatment system included six (6) under detention system two (2) of which were infiltration systems. Approximately 1,700 feet of 36 inch perforated pipe was installed for the infiltration system and over 8,400 feet 36 inch was installed in the underground detention systems.
National Grid/Advanced Building Core Performance – “Superior Energy Efficient Design for High
Saint Mary Saint Mena Coptic Orthodox Church
RGB was commissioned in 2005 to design this unique Coptic Orthodox Church accommodating approximately 600 parishioners. Symbolism is evident in all aspects of the design—the curved apse faces east toward the light, there are twelve windows in the wall of the main dome representing the twelve disciples, and the west end of the building is flagged by twin towers identifying the main entry. The exterior of the building is constructed of white synthetic stucco, synthetic masonry, white roof membrane, red Spanish tile roofs, arched roofs at the transepts and main entry, and topped off with six domes. The main dome spans 36 feet and is accented with a sparkling gold finish. The building was completed in the 2011 for a total cost of approximately $8 million.
A portion of the AT Cross building in Lincoln, RI was converted into high end office space. As part of this project the existing 545 vehicle parking lot had to be upgrade and an additional 450 vehicle parking lot was designed.
The stormwater management system consists of five (5) separate underground extended detention system. Pretreatment was accomplished by utilizing six (6) Vortsentry Model VS30’s as pretreatment devices.
The existing Post Office parking lots were experiencing server-flooding conditions and as a result, RGB was engaged to design a storm drainage system to mitigate the flooding. Infiltration tests were conducted on the in-situ soils and a series of dry well with a water quality inlet were designed and installed and eliminated the flooding.
RIPTA Para-Transit Center
The Rhode Island Public Transit Authority constructed a new Para-Transit Maintenance and Storage Facility with associated drives, parking areas, walks and landscaping. The site is located on Elmwood Avenue between Longfellow Street and Warrington Street in the City of Providence, Rhode Island
Minimizing the amount of impervious surfaces, adding Water Quality Inlets and Vortechs stormwater treatment system, providing underground infiltration/detention systems, Eco-Stone previous pavers, Bio-Retention and maximizing landscaped areas are all part of the stormwater management plan.
Ten shallow infiltration/detentions systems have been designed at locations where ground water separation and minimal cover could be achieved. These systems have overflow/outflow pipes, which connects to a closed drainage system. The customer parking area, except for the handicap parking and drop-off area, will be utilizing Eco-Stone Pervious Pavers to provide infiltration. The southern parking area and northern service drive adjacent to the building will also be utilizing Eco-Stone Pervious Pavers to provide infiltration. A bio-retention area was constructed in the north-west portion of the site to provide additional infiltration.
Runoff is treated prior to entering the infiltration/detention systems with the use of water quality inlet structures. This captures and retains the bulk sediment loads prior to runoff discharging into the infiltration/detention systems. The infiltration systems are designed for 2-year, 10-year, 25-year and 100-year storm events.
Discharge for proposed conditions will not exceed the existing runoff volume or discharge rates of the 2, 10, 25 and 100-year storm events.
As part of the on-site fire protection system, approximately 700 of 8-inch ductile iron pipe had to be installed.
RI State Police Public Safety Complex
RGB designed the new 56,000 sf Rhode Island State Police Headquarters & E9-1-1 Emergency Telephone System Facility. The building is certified LEED Silver. LID methodologies were used to obtain points for LEED. The 40-acre site is located in a RIDEM Critical Resource Area and both the On-site Wastewater Treatment System (OWTS) and the stormwater treatment systems needed careful design.
To provide fire protection to the facility, a 40,000-gallon fire water storage tank with a turbine fire pump is provided. Over 1,200 feet of 8-inch ductile iron pipe and 460 feet of 6-inch ductile iron pipe are in the distribution system.
Minimizing the amount of impervious surfaces, adding Water Quality Inlets, providing an Infiltration Basin, Sediment Forebay, and maximizing landscaped areas are all part of the stormwater management plan. Runoff generated from the proposed building roof, side, and rear parking areas and a portion of the site will flow through closed drainage systems to an on-site infiltration basin. Runoff will be treated prior to entering the infiltration basin with the use of water quality inlet structures and a sediment forebay. This captures and retains the bulk sediment loads prior to runoff discharging into the infiltration basin. The infiltration basin is designed to store the excess runoff from the 100-year storm event. Discharge for proposed conditions will not exceed the existing discharge rates of the 2, 10, 25 and 100-year storm events. Since there was sufficient land to permit an above stormwater treatment system, an infiltration basin was selected to regulate runoff both rates and volumes up to the 100-year storm.
Providence Housing Authority, HarfordPark, Phase III
The comprehensive modernization of the Hartford Park development consisted of building and site improvements (including asbestos removal) as well as the demolition of three high-rise buildings.
This $525,000 project consisted of the design of four (4) new parking areas for 150 vehicles, lighting, a new tot lot, landscaping and dumpster location/orientation improvements for their Barry Road housing facility.
The Narragansett Bay Commission would not permit any additional storm water to be discharged into their system. The LID techniques selected were based on soil evaluations, seasonal high groundwater and land availability. Four (4) underground infiltration systems with water quality inlets serving as pretreatment were utilized at each of the parking lots.
RI School for the Deaf
RGB was awarded the prestigious task of designing the new Rhode Island School for the Deaf. The new facility is built on the site of the existing school in Providence and was completed in the fall of 2010. This design allowed for the existing school to remain in use until the new facility was completed.
The project provides parking for approximately 145 parking spaces with 1500 feet of roadway/driveway construction.
The Narragansett Bay Commission would not permit any additional storm water to be discharged into their system. The LID techniques selected were based on soil evaluations, seasonal high groundwater and land availability. An underground infiltration system was installed to pick up and infiltrate all of the new building roof runoff.
Marian Fathers of Immaculate Conception
The Marians of the Immaculate Conception has been designated as a National Shrine. RGB was commissioned to provide infrastructure improvements on the property.
The road that stretches from the Pine and Vine Street intersection to the Eden Hill Recreation Center was rebuilt. A small existing bridge that spans a creek over the road was reconstructed with a precast concrete bottomless box culvert with stone abutments to reflect the character of the former bridge abutments. A detention basin for stormwater runoff was designed and constructed downhill from the two parking lots. A fire suppression system was designed for the property, which feeds fire hydrants and sprinkler systems in several Eden Hill buildings. A port-a-dam was utilized to permit the construction of a fire pump intake structure and concrete pad in the existing fire pond.
