Severino Trucking was awarded the largest construction project the State has put out to bid in May of 2016: The Newington/Dover Project. This project is the final phase of construction that will connect the Spaulding Turnpike from the Dover Toll to Exit 1 at the Pease Trade Port with a four-lane highway for both the North and Southbound lanes. The project involves not only the widening of the Spaulding Turnpike, but also the construction of a full access interchange at Exit 6; removal of the existing US Route 4 Bridge over the Spaulding Turnpike along with the construction of a new bridge, construction of a roundabout at the intersection of US Route 4/Spur Road/Boston Harbor Road; construction of 18,000 lf of sound walls; and City of Dover water and sewer relocations.
The Dover/ Newington project is one of the most complex projects to date being that has 8 traffic phases and subsequent phases within those to complete the project. There are also new items to Severino that will need to be completed for the project: one being High Modulus Columns that will support footings on the new US Route 4 Bridge and the other bring micro tunneling for new water and sewer lines under the Turnpike.
Along with the new items are the standard construction items that are very familiar to Severino Trucking, but will be done on a much larger scale. Some of these items include 210,00 cy of excavation, 231,000 cy of embankment-in-place, 250,000 cy of selects, 85,000 tons of pavement, 262,150 sf of wood panel sound walls, 31,000 lf of drainage pipe, 468 drainage structures, two sewer pump stations, 3,700 lf of sewer pipe, and 3,000 lf of water pipe.
This project is an apartment complex development that is scheduled to be phased over a three-year period. It involves a large amount of blasting, ledge excavation, and rock fills, as well as a complicated Class B stone slope. There is a large amount of underground utility work, as this development is serviced by town sewer, water, and gas. It also includes a water booster pump station constructed by Apex Construction (?). The utility infrastructure is located 1500 feet +/- from the site which will require an extensive reconstruction of Stonehenge Road. This multi-phase project is scheduled for completion in the 2020 season.
CHESTNUT STREET STREETSCAPE PROJECT
This roadway project located in the heart of the City of Portsmouth is a high-profile streetscape enhancement. Work included a complete infrastructure replacement of city sewer, water, drainage, gas, and utility conduits. Due to the aggressive schedule dictated by the busy event season, two crews worked simultaneously on this compact street and alley-way. Featured highlights include converting the street from pavement to a new hardscape surface from face of building to face of building. Granite benches, seating, and extensive landscaping were designed to encourage community gathering in this historic area, including the Portsmouth Music Hall and African Burial Ground.
GRANITE RIDGE MARKETPLACE
Work completed for the Granite Ridge Marketplace job consisted of the paving of 17 acres of the 2,100' of Perimeter Drive. It also included 246,000 squarefeet of building pads, as well as prepping 2,800” of 60” CMP detention system. This project also included gravel wetlands, infiltration basins, curbing sidewalks, light pole bases, striping, landscaping and signage.
CANDIA FIRST STOPPE
The Candia First Stoppe project began early 2017 with plans to expand their existing site. A large portion of the site expansion includes blasting ledge as well as crushing and processing material in order to get the site ready for a larger parking area for both cars and tractor trailers as well as an anticipated building expansion.
Severino Trucking was awarded this project in February and began work for the upgraded wastewater facility in mid-April. Plans for this project include the excavation and removal of about 7,000 yards of sludge as well as putting in over 15,000 LF of pipe on site. The treatment plant project will also include the excavation for 9 buildings, 3 clarifiers, and an aeration tank.
