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.

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.”

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.

Port Newark Corbin Street Berth 3 Reconstruction

Reconstruction of essential culvert and road realignment at the third largest port in the country.

Corbin Street, a primary north-south roadway serving New Jersey Marine Terminals Port Newark and Port Elizabeth, is supported structurally by Berth 3 – one of the Port Facility’s oldest wharf structures.  After a partial collapse of the seawall due to marine borer activity, the site has been actively under construction to meet PANYNJ’s high standards for quality, safety, durability and reliability.

Work performed was the construction of temporary utility supports which cross the culvert at Berth 3; reconstruction of the culvert structure; provide closure between the wharf structures at Berth 2 and Berth 3; realignment of Corbin Street including excavation, backfill, grading, drainage, and paving; and other related work at Corbin Street and Berth 3 and the vicinities thereof at Ports Newark and Elizabeth, New Jersey.

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.
