Settlement on Sixth St.
Dover, New Hampshire
This project was the site development for fourteen new custom homes. The work included selective clearing of forests, stormwater management detention, and stormwater release quality control. All underground infrastructure was installed. Municipal water, sanitary sewer, electrical, and communications were completed in anticipation of the construction of new custom homes.
The site had protected wetlands and a high seasonal water table. The critical path was to control storm and groundwater and stabilize the existing embankment soils. Stormwater control allowed the construction of the infrastructure and roadway construction to continue.
NHDES Construction and Operations Facilities
Concord, New Hampshire
The facilities when completed will house the Construction and Operation Support for the New Hampshire Department of Environmental Services.
This project includes the construction of two buildings. These buildings support the equipment, marine craft, carpentry, piping, steel, and personnel needs of NHDES.
Some challenges we have faced on this project were the controlled eradication of an existing invasive species, ledge rock removal, and poor subsoils. The existing soil conditions were extremely sensitive and unstable to moisture. Subgrade drainage was employed, as well as the use of engineered geotechnical matting, and geotechnical fabric soil separation.
To service the fire suppression systems in both buildings, an underground 40,000-gal cistern and pump station were constructed. Both underground structures were built below seasonal water tables.
Weeks Public Library
Greenland, New Hampshire
White Birch Armory
Dover, New Hampshire
The White Birch Armory project is the construction of a retail gun store with an attached, enclosed firing range. Built on a green acre site, improvements include clearing the land, stripping the site, and exporting over four thousand cubic yards of overburden to regrade the site to new design contours. Storm water retention, and associated storm and control structures were required. The building is serviced by new underground sanitary sewer, water, and electrical systems. The greatest challenge for the project team was the need to have the retail portion of the building open for business May 1, 2020 due to the owners relocation schedule. The project broke ground on December 1, 2019. The foundation construction was on critical path leading into the historically coldest, and wettest months of the year. On January 19, 2020 storm water was under control, the foundation was complete, back-filled and ready for superstructure, on schedule.
Weeks Library is the construction of an addition, that when complete would more than double the size of the existing library. The construction was completed while the old library remained open to the public. The addition, once complete and occupied was followed by a full renovation of the existing facility.
The site, albeit a residential setting, was consumed by the addition and the needed Water, Natural Gas, Sanitary, Storm Water, barrier free features, and parking infrastructure. The addition included a full basement. A construction easement by abutters was needed to allow access for construction. Final construction of rear access to the addition was completed within one foot of property lines.
Critical scheduling was required. Deep utility excavations near the addition were completed first. Foundation excavation followed. Once the building construction was underway, site storm drainage, onsite sanitary sewer infrastructure, and utilities were constructed. This work was coordinated to allow uninterrupted access to the critical path building construction.
YMCA Camp Belknap
Mirror Lake, New Hampshire
Camp Belknap Main Campus Sewerage Treatment Project involved the construction of a new sewage treatment system, sanitary sewer trunk line, and lateral system to replace an existing treatment system. The existing system, an open lagoon and spray irrigation system, became outdated and under capacity for the camp's long term master plan. The greatest challenge for the team was to construct the new system while the old system was on-line supporting camp summer programs. The system, designed for maximum flow during the active summer season, required commissioning during the camps peak enrollment time. The phased decommissioning of the existing system while operational commissioning was accomplished through planning and scheduling with all members of the project team as well as the state agencies having jurisdiction.
Wolfeboro Public Library
Wolfeboro, New Hampshire
Wolfeboro Public Library project was the construction of an addition, an entire wrap-around facade, and full renovation of the existing library. A new BMP storm management system, BMP Rain garden retention system, site lighting, new electrical and communication systems underground, water services to support fire suppression systems, as well as doubling the parking capacity was required.The greatest challenge for the project was the library's plan to stay open to the public as well as continuing to provide a variety of programs to the community throughout the construction process. Site phasing plans were required in addition to attention to public access and public safety during construction were critical. Wolfeboro, a popular summer resort town, made what it typically the most productive months for construction, the most challenging during construction as the summer population grew.
Somersworth, New Hampshire
Ground up construction of a Cumberland Farms convenience store and fueling station. Site work included foundation construction, Building underground infrastructure, parking irrigation and landscaping. Traffic control and signage planning on state highway Rt 106 and Blackwater Road were required for improvements made. The largest project challenge was the accelerated schedule restraints placed on the project team by Cumberland Farms, for business reasons. Start to finish, doors open for customers 4 months!
Rochester City Hall Annex
Rochester, New Hampshire
Renovation of the existing town annex. Formerly the Rochester Fire Station dating back to horse drawn apparatus. The Annex is directly adjacent to the Rochester Town Hall and Opera House on one side and the active Rochester Fire House on the other. Barrier free access was maintained to the town hall and Opera house throughout the site work construction. The site work included new underground infrastructure, new emergency power for the active Fire Station. A new public space courtyard/ hardscapes and parking.
Integrity Earthworks was contracted by Bonnette Page & Stone Construction to perform site work and utility work at The Mill on River Bend, in Franklin New Hampshire. The project consisted of the historic preservation and renovation of the existing mill building and site for the use as residential apartments. The site is located on the Winnipesaukee river where it drew from the hydro power of the river flow. This Mill however did not have the conventional mill wheel, but rather turbines located in the bottom of the mill driven by a penstock (a sluice or intake structure that controls water flow, or an enclosed tunnel that delivers water to hydro-turbines). The penstock drew water from the river ½ Mile upstream, and down through the center of the site. The existing building literally had a river running through it. Many parts of the remaining turbine machinery would be used as architectural elements in the finished building. The site work included locating the penstock to avoid conflicts when coordinating underground utilities. Because of the nature of the first floor being 50% below grade, the need to bring in outside light, and outside awareness to residents on the lower floors, retaining walls were constructed adjacent to the building. These areas required drainage. Site conditions required these drains to travel under the building to the river's edge. A central courtyard was constructed as an outdoor gathering area. This area required hardscapes, granite benches constructed of stone found on the original mil sire, some of the old mill machinery as features, as well as extensive landscaping.
