Conti’s scope on the project will include grading, drainage, paving, curb and gutter, traffic control, pavement markings, retaining wall construction, and erosion control.
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
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.
Deemed a “financial and social disaster for communities and taxpayers,” a failed housing development project in the early 2000s resulted in extensive site contamination.
In 2009, a private company spearheaded a project to remediate the site as part of a surety bond, and New Jersey Governor John Corzine approved the plan. Conti performed under a series of closure contracts across the Meadowlands’ different landfill sites for potential non-residential future redevelopment.
Conti’s work consisted of site preparation activities, installation of the balance of a site wide leachate transport system and perimeter engineering controls. Work included the installation of a vertical hydraulic barrier; dewatering of surface water, groundwater and leachate; installation of a leachate collection and transportation pipe, force main systems and pump stations; Viola Ditch modifications, landfill cap installation and site improvements at the Lyndhurst Landfill. Work was completed simultaneously on the Avon Landfill with identical scopes of work.
During the repair and installation of the leachate collection system, Conti placed 14,305 linear feet of 12-inch perforated leachate management pipe with cleanouts and 6 to 8-inch HDPE leachate force main to collect and transport leachate from the landfill to the pump stations and existing collection system. Rehabilitation and construction of onsite pump stations included new power supply; control systems including programmable logic controller and SCADA; flow meters at entrances to force main; air release valves; 4KV and 5KV transformers; and pH and gas meters. Conti pumped leachate from the work area using assorted pumps, sumps, hoses and pipes to transport to a frac holding tank for disposal.
Conti achieved a perfect safety record on this project with zero recordable incidents.
Deemed a “financial and social disaster for communities and taxpayers,” a failed housing development project in New Jersey’s Meadowlands in the early 2000s resulted in extensive site contamination.
In 2009, the American Home Assurance Company (AHA) spearheaded a project to remediate the site as part of a surety bond, and New Jersey Governor John Corzine approved the plan.
Conti completed the closure of the Meadowland’s 85-acre landfill with a soil cap as a part of the AHA’s remediation efforts. The landfill included an impermeable soil layer, residential clean fill material, topsoil and landscaping. Conti performed storm drainage installation, methane collection system repairs and leachate collection system modifications. Conti installed water-tight HDPE storm drainage, 110 precast manholes, and drainage swales with a continuous HDPE liner, all through refuse material while avoiding existing landfill utility conflicts. The team also relocated 250,000 cubic yards of contaminated soil.
As one face of the landfill had previously been covered with liner, Conti was required to inspect and repair defects left behind. To protect this liner, a specialty drainage layer and topsoil were placed over the top to allow for stormwater to pass into the drainage system. Conti utilized GPS technology on dozers, resulting in reduced costs in survey and stakeout of the project. Conti’s flexible team approach led to the successful completion of this project and award of the next contract at an adjacent landfill, both on acreage intended for beneficial reuse.
As part of the Ephesus Church/Fordham District renewal, transportation improvements in the district have been implemented over multiple phases to address bicycle, pedestrian, auto, and transit concerns.
The extension, which is estimated to potentially carry 7,800 vehicles each day, would connect Fordham Boulevard to Ephesus Church Road from the existing South Elliott Road and end in a roundabout.
Conti will perform Phase II construction of roadway widening along Elliott Road, Fordham Blvd, and Ephesus Church Road. The project will include grading, drainage, paving, curb and gutter, traffic control, pavement markings and markers, erosion control, signing, signals, culvert construction, and other related items.
