Lincoln Area Sewer Separation, Portsmouth, NH

Lincoln Area Sewer Separation located in downtown Portsmouth, NH is the largest pipe project that Severino Trucking has had to date.  The main purpose of this $5.5M project is to separate the storm water system from the sewer system.

In order to do this, 2500 lf of new 30" PVC sewer main will be installed along with 850 lf of 24", 550 lf of 12", 440 lf of 10" and 2200 lf of 8" that will connect six side roads and re-route 1300 lf of cross county sewer that now exists.  One hundred thirty homes will also have new sewer services installed.

The storm water that currently runs into the sewer system will now run in a new drainage system consisting of 1700 lf of 48" RCP pipe along with 4500 lf of new drainage pipe that ranges from 12" to 42".

Not to be left out is the installation of 3800 lf of 12" DI water pipe and 2400 lf of 8" DI water pipe along with almost 4,000 lf of service pipes to the existing homes.

This is a particularly challenging job not only because of the tight quarters, but the depth of the pipe (up to 18') and the 12' of ledge that needs to be removed.  The project began on September 7, 2010 and is scheduled for completion summer of 2012.

Spaulding Turnpike (NH Route 16)

Newington/Dover

This project is a joint venture with Cianbro Corp. which involves the construction of a new
bridge to carry two north and south bound lanes over the Little Bay as well as a new pedestrian
bridge accessing the old General Sullivan Bridge.

Construction of 2300 LF of mainline will shift existing lanes onto the new four lane bridge to
allow the existing bridge deck to be overhauled in the next phase of highway improvements.

As for Hilton Drive, 2700 LF will be completely reconstructed and will allow two-way traffic to
access Hilton Park east and west.

Three MSE walls will be constructed-GSB pedestrian bridge approach, mainline bridge abutment
and along Hilton Drive to hold back mainline embankment all totaling 14,000 SF and ranging
from 8’ to 33’ in height.

Sound walls will be constructed atop 700 LF of the MSE wall on the west side of mainline.

Access for the Little Bay Bridge construction will include building a causeway 150 feet out into
the bay from each shoreline using 20,000 CY of class B stone up to 20’ below average water
level and 10’ above and 75’ wide. This was a challenge considering Little Bay has the strongest
currents in the U.S.A.

Material totals to complete this project will include 24,000 CY of gravel for under pavement,
12,700 ton of asphalt, 65,000 CY of common excavation, 45,000 CY of fill place, 12,000 SY of
invasive species control, 7,000 LF of drainage pipe, 122 concrete drainage structures, two large
storm water leeching galleries (BMP’s), 5,700 LF of granite curbing, demo and abatement of
three existing buildings, along with hundreds of other incidental items.

Job start date was 9/1/2010, and is scheduled for completion in October 2013, with the majority
of this time for the actual bridge construction.

Rochester, NH

Exit 15, Spaulding Turnpike - Construction of approximately 0.5 miles of new northbound and southbound mainline, including realignment of the existing northbound and southbound on and off-ramps.

Work will include the replacement and widening of four existing bridges; Route 11 over Route 16, Route 16 over the Cocheco River, Route 16 over the abandoned B&M railroad, and Route 16 over Chestnut Hill Road. Also, one new bridge will be created for the southbound off-ramp over the Cocheco Backwater.

The new alignment requires the relocation of the City of Rochester’s existing 10” force main and 20” water main that runs under Route 16.

Drainage relocations will require jacking a 48” RCP under Route 11.

Route 11 will be reconstructed and widened to double its current width to accommodate the new on and off-ramps.

The new mainline and ramps will require over 400,000 CY of imported material for their construction.

The bridges will use 4.7 million lbs of steel and 12,000 CY of concrete.

Completion of the $28.8M project is scheduled for October of 2012.

Salem to Manchester #14633F

This NH DOT project situated in Londonderry, NH consists of constructing two miles of the north and sound bound barrels of Interstate 93.  Four red-listed bridges will be replaced as a result of the widening.  A half-mile of Route 28 (Rockingham Road) will be reconstructed and widened to improve traffic flow through the area.

The pipe crews will be converted to lagging and wall crews.  The new wave of bridge design are again utilizing MSE walls as the wings and abutments for the bridges.  Once the walls are done, the bridge crews can go to work on the seats, girders and decks.

Upon completion of the south bound barrel in the fall of 2012, the north bound traffic will join the south bound in a contra-flow traffic pattern all on the south bound lane allowing construction of the two miles of north bound to be completed without phasing.

In addition to the work at Exit 5, a wetland mitigation at Exit 4 will furnish the sand layer for the project.  One thousand feet of South Road will be reconstructed and a new box culvert will be installed to relieve flooding in the area.

The Cottages of Durham

This project is located in the Town of Durham, NH and is intended to help supply housing for the nearby University of New Hampshire.  The site sits on a 41 acre parcel with woods surrounding the site.  Privately owned and managed, the project consists of 41 single and duplex buildings that will occupy 619 residents along with a clubhouse and outdoor pool.

Town sewer and water will be installed along with natural gas and underground electrical.  Paved roadways, granite curbing, concrete and paved walkways are all to be installed once the 24,000 cy of excavation and 75,000 cy of embankment materials have been placed.

The project will be built in four phases, completing in the fall of 2012.

Exeter, NH

The Boulders at Riverwoods is 96,000 SF two-story retirement housing community surrounded by 24 independent-living cottages located in Exeter, NH. Twenty-two acres of trees were cut to open the area for earthwork that included 80,000 CY of excavation, boulder removal and ledge, and 22,000 CY of structural fill to support the building footings and slab.

Utilities include of 4,000 lf of sewer pipe, 2,200 lf of water main, 7,500 lf of drainage pipe, 115 concrete drainage structures, 43,000 lf of stormwater detention galleries and a 16’ x 36’ three-sided box culvert.

11,000 of Redi-Rock retaining walls were installed and existing boulders were placed to construct another 2,000 sf.

20,000 CY of select gravels were covered by 5,600 tons of pavement. 10,000 lf of granite curb and 1,500 SY of concrete sidewalks were placed to finish the flatwork.

The site will be completed with 30,000 SY of loam to be spread and seeded between the landscaping consisting of 350 trees, 720 shrubs and 2,580 perennials and groundcovers.

Epping, NH

In August of 2009, the second phase of construction started at The Brickyard. This work included the remainder of cut and fills to bring the site to sub-grade along with all utilities and paving for the first half of the site which is to include the Market Basket grocery store. The Store is planning to open in January-February 2010 requiring all site work to be completed by the end of November 2009. This schedule crammed an amount of work which normally would be spread over an entire season into a period of less than four months.

Newmarket, NH

This project consisted of utility replacement and complete roadway reconstruction in the heart of downtown Newmarket, NH, providing existing homes and businesses with new sewer and water services. The project included 1,100 lf of 10” and 8” sewer mains, 3,800 lf of 16”, 12” and 8” water mains and 2,800 lf of drainage.

In addition, overhead cabling was replaced with 65,000 feet of conduit to provide new underground power, phone and cable services. New granite curb, concrete sidewalks and ornamental light poles finished the new look of the downtown area.

The major challenge was to complete the work while limiting the impact on the downtown businesses. Traffic was redirected to one-way in order to maintain traffic flow and adequate parking. Work was done in 3 phases to accommodate the needs of the businesses, the traffic and the construction work.

Londonderry, NH

This NH DOT project situated in Londonderry, NH consists of moving the existing southbound on and off-ramps and the northbound on-ramp. This will allow the future phase of construction to widen the north and south bound barrels of Interstate 93 while in the meantime increasing acceleration and deceleration safety on the new ramps.

This presented new challenges for the Severino crews, as it was our first attempt at H-pile and timber lagging, and large panel MSE walls. During the late fall and winter, the pipe crews were converted into “shoring” and “wall” crews. The new waves of bridge design are utilizing MSE walls as the wings and abutments for the bridges. Once the walls are done the bridge crews can go to work on the seats, girders and decks. Not only are the bridge abutments constructed with MSE walls, but 1300’ of the northbound on-ramp embankment next to a swamp is held up by a wall that ranges anywhere from a 15’ to 30’ high.

80,000 CY of ledge was blasted on the side of Interstate 93 for the new southbound onramp. This was combined with 40,000 additional yards of import to complete the southbound off-ramp embankment.

Madbury, NH

This project consisted of replacing the Route 155 Bridge over the Boston & Main Railroad, realignment and reconstruction of two miles of Route 155, and the relocation and construction of Pudding Hill Road in Madbury, NH.

Due to the unstable soils under the proposed bridge footings and realigned roadway, 36,000 vertical feet of wick drains were installed and the area was surcharged for five months being monitored by five settlement platforms. When the settlement was done, 331 lf of drilled shafts and 120,000 lbs of steel bearing piles were installed to support the new bridge footings.

The major utility work included the relocation of the existing 24” concrete transmission water line that feeds the abutting town with new 24” ductile iron pipe. This required the installation of three temporary line stops to maintain water flow during the relocation. Before the new pipe was installed, 300 lf of 42” steel sleeves had to be jacked under the railroad and Route 155 to support the new water line. 170 lf of 48” RCP was also jacked under Route 155 to replace existing drainage that was to be removed.

Phased detours were constructed throughout the project to maintain two-way traffic at all times. 27,000 CY of select gravels, 6,700 tons of pavement and 10 miles of painted lines finished the project.

Dover, NH

A $2,140,000 job is not a bad project for the summer… just trying doing it in 13 weeks. On June 2, 2008, silt fence was installed and on August 29th, 2008, the last sidewalk paver was placed and islands loamed. A week of cleanup followed and the storm was over.

During that time, 20,000 cubic yards of material were excavated, 400 linear feet of fire and domestic water pipe, 3,000 linear feet of drainage structures, 300 linear feet of sewer services and 4,200 linear feet of site lighting with 72 light bases was installed.

The parking lots required 6,000 cubic yards of gravels, 3,600 linear feet of granite curb and 3,400 tons of pavement. To support the parking lots, 14,000 square feet of retaining walls was constructed. To finish off the look, 21,000 square yards of lawn were loamed and seeded as well as 2,000 square yards of concrete and bituminous sidewalks placed.

That was just the on-site work! New electrical services and lighting wall-packs were installed in the school as well as new mechanical duct work and louvers. Existing windows were removed and bricked in to accommodate the new grade change at the entrance of the school.

The new entrance to the school required widening 1,000 linear feet of Dover Point Road, grinding the existing pavement markings and re-striping to accommodate the new turning lanes.

Dover, NH

The project began in spring of 2006 and was comprised of two separate projects. One of the projects was to rehabilitate the parking areas of the existing office building and publishing center which provided office space for over 1,500 employees. The second was to complete site work and parking garage for a new four story office building to facilitate an additional 2000 employees to campus.

The site work for the office building included the vast majority of work with extensive excavations and fills to accommodate the new structure and parking facilities. Over 100,000 CY of excavation was required in a variety of soil conditions ranging from ledge to wetlands, with the bulk being a silty clay based soil. In addition, over 60,000 CY of structural fill were imported to site to fill building and parking areas. The utilities included over 8,000 lf of drainage, 3800 lf of water main, and 500 lf of new sewer main along with 75 manholes and catch basins. Site electrical excavation and backfill was part of both projects including approximately 20,000 lf of trenching and over a dozen large manholes for electric and telephone conduits. To complete the project over 30,000 CY of gravel were placed, 8,000 tons of binder pavement placed and 23,000 lf of curbing installed, along with a precast pedestrian bridge and 500 lf of walkway to connect the new building with existing campus.

The rehab to the existing parking lot incorporated significant challenges of its own. All work needed to be done without disrupting normal operations of a facility which housed over 1,500 workers. Nearly 60,000 SY of existing pavement needed to be removed, the sub-base excavated and 32,000 CY of gravel placed. While this was happening, over 40 drainage structures were reconstructed and dozens of water and sewer structures needed to be adjusted prior to the placement of 6,000 tons of binder pavement. The site also included new electric and security conduits, underdrains, and 20,000 lf of curbing.

Both projects were completed in August of 2007, culminating 16 months of cooperative efforts with the General Contractor and dozens of subcontractors to provide Liberty Mutual with a campus that would more than double the workforce in Dover, NH.

Rochester, NH

The Flatley owned property at Exit 13 in Rochester, NH was no stranger to Severino when the project started in September of 2006. The relationship started as a “cleanup” of an abandoned development that failed in the late 80’s. Unprocessed ledge piles and unblasted ledge faces rendered the site undevelopable. After a few years of being able to process the material for use on other projects, the developer pulled the trigger with some big name tenants. Lowe’s, Kohl’s and Starbucks all came to the table with aggressive schedules.

The Severino crews went to work on the 39 acre site immediately. 100,000 CY of ledge still needed to be blasted. 60,000 CY of existing uncompacted fills needed to be reconsolidated in the Lowe’s and Kohl’s building pads. The Kohl’s pad was completed in the late fall of 2006.

Pipe crews laid the deep drainage trunk line all winter while the Lowe’s building pad and parking lot were blasted.

When spring hit, the Lowe’s pad deadline was June 1st and the offsite work was started. A new southbound on-ramp was constructed, and Route 202 was widened to accommodate left turn lanes and increased traffic flow. A new sewer main was constructed a half mile up to the site from the downtown area.

Crews diligently worked towards the October 1st deadlines for the three stores. It seemed as though paving occurred once or twice a week (and nights on the offsite) as the deadline was met.
