NCDOT Bridge 87 over Norfolk Southern Railroad

Bridge No. 87 is located on NC 33 over Norfolk Southern Railroad, in Pitt County.  NC 33 is the main route from Grimesland to Greenville with a high amount of truck traffic and school buses.

The existing bridge is 212 feet long and approximately 32.7 feet wide, carrying two lanes of traffic. Built-in 1938, Bridge No. 87 is considered structurally deficient. The replacement structure will be a three-span bridge approximately 287 feet long, with two 12-foot lanes and 4-foot shoulders.

Construction of the roadway grade of the new structure will be raised approximately 4.5 to 4.75 feet from the existing structure to provide required clearance over Norfolk Southern Railroad. The approaches will be widened to include a 32-foot pavement width, providing two 12- foot lanes and a minimum of 4-foot paved shoulder. Traffic will be maintained on the existing bridge during construction.

NCDOT Bridges 109 and 121 over Buffalo Creek

The existing bridges consist of five spans for each with full length of 200 feet, they were originally constructed in 1957, and 1964. both Bridges considered structurally deficient, degraded for posted load limit, and functionally obsolete meaning it was safe to travel on but had reached the end of its useful life.

The replacement bridges will be three-span bridges approximately 210 feet long with two lanes for each and sidewalks one on each bridge.  During construction the traffic will be pushed on one of the bridges and shift two-lane one way to two-lanes two-way so that phase one can be completed by demo the existing bridge and construct the new bridge structure, once phase one is completed the traffic will be pushed onto the new bridge structure and proceed with the construction of phase 2detour the utilization of the existing structure as a detour route will allow travelers and commuters to get to the city of Greensboro with no interruptions during the construction of the new bridges.

NCDOT Bridge 216 over Buffalo Creek

Bridge No. 216 was constructed in 1957. The two-span bridge is 51 feet long with a deck width of 25 feet. The structure type is timber floor on salvaged I-Beams.

Bridge No. 216 will be replaced in-place. The bridge is currently closed (closed since 2010); local traffic is diverted to an off-site detour. The proposed structure would be an 87.38-foot long two-span cored slab bridge. The bridge typical section is two 11-foot lanes with a 10-foot center turn lane, approximately four-foot bridge offset, and an eight-foot wide accommodation for future multi-use path on the south side of the bridge. The proposed design speed is 40 mph. The project overall length is approximately 600 feet.

NCDOT US17 Hampstead Bypass

U.S. 17 is a heavily congested highway in Hampstead, where an average of 43,500 vehicles travel each day. This major construction project will improve traffic flow and safety in Pender and New Hanover counties.

Conti is constructing a four-lane, divided highway on a new location, known as the U.S. 17 Hampstead Bypass, between an area south of N.C. 210 that connects to U.S. 17 north of the Topsail schools, a distance of 5.6 miles. The project will include new interchanges with bridges, ramps, and loops at N.C. 210, Hoover Road, and U.S. 17 north of Vista Lane.

As part of this contract, nearly a mile of U.S. 17 between the new bypass and an area north of Sloop Point Road will be upgraded with raised medians. This section of U.S. 17 will be redesigned with safety features called reduced conflict intersections, which decrease by more than half the potential locations where vehicles can collide.

Spring/Fishburne US 17 Drainage Improvements

US 17 in Downtown Charleston, known as the Crosstown, is a major artery for the City and has been plagued with flooding for many years. It is critical that this route remain an efficient lifeline for emergency response vehicles, commuters, and those evacuating in times of imminent hurricanes.

This drainage project will offer a solution to alleviate frequent flooding that causes property damage and heavy traffic along this critical corridor.  It will improve drainage in an area that covers approximately 20% of the City of Charleston.

In previous phases of the project, new stormwater pipe was installed and new tunnels were installed beneath the US 17 / Crosstown corridor.

Conti is working on Phase 4 of this project, which consists of the construction of a pump station / wet well structure and a cast-in-place triple box culvert outfall structure into the Ashley River.

Once all phases are complete, the new pump station between the Ashley River Bridges will be equipped with three pumps each capable of pumping 120,000 gallons per minute, three 850 horsepower diesel engines to power the pumps (thereby eliminating the need for electricity to run the pumps), and one back-up diesel generator to run the electrical and control systems in the event of a power failure.

Once the project is complete and the pump station is online, the Crosstown and surrounding areas should remain passable in all but the very worst storm events.

Walnut Creek Greenway

The Capital Area Greenway System was first adopted by City Council in 1976. This plan proposed a system of linear parks located primarily along rivers, streams, and creeks, and included the opportunity for an interconnected system of pedestrian trails across the region.

The Walnut Creek Trail currently intersects with Avent Ferry Road, at which point a sidewalk must be used to continue the trail, along Avent Ferry Road, until the trail picks up again on Trailwood Drive. The Walnut Creek Greenway Trail at Trailwood Drive project will extend the Walnut Creek Trail from near its intersection with Avent Ferry Road to Trailwood Drive along the existing sewer easement. This extension will allow users to forgo using the sidewalk along Avent Ferry Road to remain on the Walnut Creek Trail in this area, providing a continuous 10-feet-wide asphalt trail along the entire corridor.

The project is the construction of a segment of the Walnut Creek Greenway, which will connect from the existing Walnut Creek Greenway at Trailwood Drive to NCSU Centennial Campus in Raleigh. It is about ¼ mile in length and will include one bridge crossing. The project generally includes clearing, grading, storm drainage, erosion control, utilities, asphalt multi-use path, signage, pedestrian bridge, asphalt paving, concrete sidewalk, and structural components along the Walnut Creek Greenway

This project will increase the Port’s ship berthing capacity as well as improve upon the safety and efficiency of terminal truck traffic to and from the Ports, extending Conti’s expertise in construction of marine projects while continuing our delivery of superior construction services to our clients. 

The team safely managed construction activities while avoiding any potential impact to operations of the Port and adjacent Newark Liberty International Airport. 

St. George Ferry Terminal Design-Build

Conti managed this massive design-build effort, organizing nearly 50 subcontractors and trades to deliver ferry terminal renovations on time and budget.

​Conti was the design-build firm selected to design and reconstruct eight elevated concrete and steel structures and completely rebuild a ninth structure, all during ongoing terminal operations of 70,000 patrons per day. The team demolished existing structures, made extensive steel repairs, constructed new deck pans, poured lightweight concrete decking and remediated hazardous material.

Conti Professional Services (CPS) provided extensive client coordination, value engineering and design innovations for this project. As savings to the client, Conti removed unforeseen asbestos, re-sequenced traffic patterns, added more bike paths and re-engineered a T-wall structure— lowering project costs and increasing the value of the final product.

The project’s North Ramp was the focus of a great deal of value engineering. Modifying the design from a 3-span elevated steel structure to a 2-span elevated structure with integrated T-wall and pre-cast T-sections reduced overall construction and long term maintenance costs. Conti also collaboratively re-sequenced traffic patterns to eliminate the addition of a temporary bridge structure, which had zero impact to the schedule and provided a substantial credit to the client. Significant savings on structural steel materials were also achieved when value engineering identified lightweight concrete as a way to limit the weight of the ramps.

In addition, Conti engineers designed a groundbreaking method to seal the shield containing the asbestos by installing rubber along containment areas. This innovative design utilized less water and slurry, especially over active rail tracks. CPS also suggested changing from brick façade to architectural precast masonry panels, facilitating a reduction in procurement schedule of materials and overall operation costs. The masonry panels met New York’s Public Design Commission’s goals of making the area more interesting for pedestrians and vehicle traffic.

Conti excelled in managing the project to maintain the critical path schedule when encountering unforeseen scope increase, such as when the majority of reconditioned ramps needed more repairs than initially estimated. To mitigate delays, CPS studied the schedule and adjusted the sequence of many activities. On the St. George project, Conti managed a $13 million scope increase with zero impact to the critical path schedule.

Conti won Engineering News-Record’s New York Region’s 2013 Best Project, Award of Merit for its excellent work.

Port Imperial Intermodal Ferry Terminal

In response to increasing commuter volume into New York City, Conti constructed this new, state-of-the-art port facility to include significant savings through value engineering.

Significant growth to ferry ridership at New Jersey’s Port Imperial Intermodal Ferry Terminal raised the need for major renovations to the aging structure. Its owner, New Jersey Transit, called for construction of a new state-of-the art commuter port to replace the undersized existing facility serving the millions of passengers traveling across the Hudson River between Manhattan in New York City and Weehawken.

Conti performed the design and construction of the new 65,000 square-foot ferry terminal using value engineering to improve operations and save budget. The work included environmentally sensitive dredging of the Hudson River for ferry traffic, pile-driving, precast foundations and terminal building construction, as well as an 800-foot waterfront pedestrian esplanade to provide convenient scenic access to the terminal. Conti executed this complex work over water, maintaining traffic flow on an adjacent roadway and compressing work hours to attenuate noise for neighbors. Conti managed 25 subcontractors and coordinated regularly with New York Waterway.

Providing value engineering for many aspects of the project, Conti saved the client over $6 million. Efforts included eliminating approximately 950 square feet of a terrazzo floor and replacing it with durable colored epoxy sealants and resilient flooring. The team also evaluated ferry operations and optimized the dredging area by reducing its footprint, which reduced the pay quantity by more than 30%.

Conti won an Honorable Mention by New York Construction Magazine as one of the Best Building Projects of the Year.

New Jersey Transit described Conti’s commitment to excellence as “working aggressively to meet key construction dates… without compromising quality or safety.”

Port Elizabeth Intermodal Transfer Facility

As New York and New Jersey’s most valuable container ship facility, the Port Newark Elizabeth Marine Terminal is a major component of the PANYNJ.

​The Port Authority needed to boost the efficiency of the Elizabeth Marine Terminal (known as Port Elizabeth) by adding a new Intermodal Transfer Facility. This purpose of this new facility was to take cargo from incoming trains and transfer it to ships, and vice versa.

Conti closely managed this complex design-build construction. Conti’s construction of the Intermodal Transfer Facility included four miles of railroad track and 110,000 cubic yards of asphalt pavement for the entire site to provide “free range” movement of Reach Stackers and Straddle Carriers used to perform transfer between transport mediums. The team also removed 4,000 feet of existing rail and reclaimed 138,000 square yards of existing asphalt pavement for re-use, saving time and money. Additionally, Conti self-performed all grading, earthwork, placement of ballast, utility installation or relocation and track installation work.

Conti rerouted or removed a complex network of utilities, including 4,500 feet of water main, power/communications duct banks, and 12 100-foot-tall High Mast Light Towers founded on steel pipe piles and concrete foundations.

Working with our designers, Conti developed a creative approach to project planning. We systematically devised separate design packages to coincide with the three phases of work so that construction activities could begin on-site prior to completion of final design to expedite the project schedule.

Conti worked through complex utility re-routings and challenging site logistics to construct PANYNJ’s new facility all with minimal disruptions to rail traffic.

Penn Forest Dam

Conti received the American Council of Engineering Company’s national Honor Award for Water Resources and the Association of State Dam Safety Officials’ National Rehabilitation Project of the Year.

Suffering from a series of complications since its construction in 1960, the Penn Forest Dam had continuing problems with weep holes, seepage and a 15-foot sink hole. As critical infrastructure, the dam supplies a source of water for the community from the adjacent reservoir. The City of Bethlehem sought to remediate the dam’s structural issues and address flood control protection for the area.

Conti constructed the new dam which included huge structural reinforcements, raising the dam’s walls by three feet to increase spillway capacity. The team constructed the dam walls and lined them with more than 2,000 six-foot-high, sixteen-foot-wide, four-inch-thick concrete panels, weighing over 3,000 pounds per unit.

Conti also constructed two on-site batch plants, one for grout, one for concrete, and a conveyor system to transport roller compacted concrete (RCC) needed for the project. Because of the sophisticated computer system used by the plant, crews kept exact concentrations of ingredients constant. Conti maintained quality control of the RCC by conducting daily tests to ensure proper temperature of the concrete across seasons. The plants operated six days per week, two shifts per day. This approach was very efficient, as it produced 6,000 tons of RCC daily.

Upon completion, the Penn Forest Dam was the third largest RCC project in the US. Conti safely delivered the project on budget, on schedule and with as little disturbance to the surrounding area as possible without losing material due to the elements.

Fenimore Landfill

Rotten egg-like smells plagued the residents of Roxbury from late 2012, so the New Jersey Department of Environmental Protection (NJDEP) chose to cap the Fenimore Landfill to alleviate the problems it posed for Roxbury residents.  

The NJDEP investigation determined the odor was caused by hydrogen sulfide generated by debris within the Fenimore Landfill. Although the NJDEP had closed the landfill in 1979, problems for the surrounding community did not arise until the early 2000s. Since then, the NJDEP has taken incremental steps toward remediating the site. 

Conti worked with the NJDEP to help reach their goal by capping 19 acres of the 65-acre landfill. The project team relocated existing garbage and waste, excavated 17,500 cubic yards of waste and earth and installed 22,000 square yards of erosion control, 300 linear feet of storm water discharge pipe and 150 linear feet of monitoring wells, in addition to constructing an access road. 

The cap itself included 97,000 square yards of geomembrane liner between 49,000 square yards of 6-inch subgrade fill and 96,000 square yards of 12-inch above geomembrane fill. Conti also placed a 97,000-yard composite drainage net over the geomembrane and 102,500 square yards of 6-inch topsoil over the cap. 

After the cap was completed, the project team revegetated the site and performed one year of operations and maintenance to monitor the success of the cap. Conti performed the project with zero safety incidents. 

Conti supported NJDEP in solving environmental concerns for the people of Roxbury in this high profile project.
