Permitting
Condition Survey and Replacement of Collapsing Bulkhead
Location: Riverbend Apartments • Jacksonville, Florida
 S. T. Hudson Engineers conducted a condition survey of an existing timber bulkhead, along the St. John’s River, which was over 800 linear feet.
Hudson Engineers designed this modern replacement for the collapsing timber bulkhead. Concrete sheet piling was chosen for long life and resistance to marine borer attack. A cantilevered design avoided excavation near the existing building foundations for a tieback system that would otherwise be required. A precast cap was doweled in place.
Hudson secured the necessary environmental permits from the respective agencies to complete this project on schedule.
Fishing Pier, Marina with Boat Ramp, Promenade and Dockmaster Building
Location: Gloucester City, New Jersey • Delaware River
 S. T. Hudson Engineers designed a fishing pier, marina (featuring twenty-four boat slips) with a boat ramp, 1,120 L.F. pedestrian promenade, and the dockmaster building at Proprietor's Park. Hudson performed field investigations, including hydrographic, archeological and topographic surveys. Hudson's scope included: obtaining necessary state and federal permits, dredging consultation, design and construction management. Hudson was responsible for the adjacent site work, including: parking facilities, landscaping, stormwater management, utilities, the creation of an inter-tidal habitat (mitigation) and ornamental fixtures.
This project was very unique due to the presence of several historic timber crib structures and a sunken historic vessel, the frigate "Augusta." Hudson located these obstructions and worked in conjunction with local and state historic preservation officials to minimize impact during construction and designed signage as an educational tool for the public. This project shall be the cornerstone to Gloucester City's waterfront development plan and a catalyst in the growth of the local economy.
Design of New Public Access Waterfront Promenade and Fishing Pier
Location: Bayonne, New Jersey • Newark Bay
S. T. Hudson Engineers was selected to enhance public access and recreation along the Bayonne waterfront. This project included demolition and removal of a 370 ft. long pier and low deck apron, and the removal of a two-story concrete warehouse which sits atop the pier. Hudson designed a landscaped waterfront promenade for the remaining 300 ft. long portion of the pier and a new 200 ft. long T-shaped fishing pier outshore of this promenade, within the footprint of the removed portion of the pier. North of this pier, we prepared design documents for removal of an unstable section of a low deck pier and bank stabilization with rip-rap.
Hudson's scope of work included: conceptual designs, sediment sampling and dredge material characterization reports, upland (pier) soil sampling, preparation of federal and state permit applications, final design and related construction documentation.
Design of a New Slag Unloading Pier
Location: Camden, New Jersey
 S. T. Hudson Engineers prepared the federal and state permit applications, developed the construction drawings and specifications, and construction management for the installation of a new slag unloading pier. The new pier is located at the SJPC Broadway Terminal. The pier supported a multi-purpose crane and conveyor system, which discharges the slag into the St. Lawrence Cement Facility. The project also included the removal of approximately 100,000 cubic yards of dredge material.
Design of the USS New Jersey Memorial Pier
Location: Camden, New Jersey
S. T. Hudson Engineers prepared preliminary designs and permit applications for permanent berthing of the eight-hundred and eighty-eight foot (888’) long USS New Jersey as a museum ship on the Camden waterfront. Hudson also prepared berthing and mooring designs to the U.S. Navy standards for the USS New Jersey at two Camden port facilities, for use during rehabilitation of the historic vessel.
Hudson was selected by the home port alliance to design the permanent memorial pier and vessel moorings for the battleship museum. Our scope of work included: permitting, design of waterfront structures and utilities, pre- and post-dredge hydrographic surveying, dredging consultation with the United States Army Corps of Engineers and technical assistance during construction.
Rehabilitation of the South Brooklyn Marine Terminal (SBMT)
Location: Brooklyn, New York
S. T. Hudson Engineers performed engineers/divers surveys on various pier and bulkhead structures along the Brooklyn waterfront. A hydrographic survey was conducted at these waterfront structures using a differential global positioning system.
S. T. Hudson Engineers prepared detailed reports with recommendations and engineer's order of cost magnitude for our client's review. Based on these surveys, the 29th and 39th Street piers and the inshore bulkhead, between the 35th and 39th Street piers, were rehabilitated for future use. Our scope of work included: obtaining the necessary permits, designing repairs, and construction management. The 33rd and 35th Street piers were scheduled for demolition. S. T. Hudson Engineers obtained separate permits for the removal of portions of these waterfront structures, which included the removal of a large warehouse. We conducted a side scan sonar survey to determine if any debris from the demolition process was an obstruction in the navigational channel.
Rehabilitation of the Delaware Station Pier
Location: Philadelphia, Pennsylvania
 The rehabilitation of the Delaware Station consisted of the installation of steel auxilary piles to replace the deficient front row piles and reinforced concrete encasements of the interior steel piles. The scope of services included underwater inspection of the pier, report with findings, recommendations, and cost estimates, federal and state permit applications, preparation of construction drawings and specifications, installation of steel auxilary piles, concrete pile encasements, and a new fender system; construction management and preparation of "as built" drawings.
City of Camden, Riverfront Promenade Extension
Location: Camden, New Jersey
 S. T. Hudson Engineers designed the extension of the riverfront promenade along the Camden waterfront. The new promenade is approximately 1,400 l.f. and extends from the North face of the former RCA pier (at the foot of Cooper Street), to the South side of the Benjamin Franklin Bridge. Hudson obtained all state and federal permits for the demolition of three (3) deteriorated structures, the rehabilitation of two existing piers and the installation of a new steel sheet pile bulkhead wall.
Our scope included the design of all new utilities, fire protection, landscaping, the creation of a major shallow water habitat for mitigation, and construction management.
The promenade has become one of the many popular tourist attractions along the waterfront.
Rehabilitation of the Ship Dock
Location: Trainer, Pennsylvania
S. T. Hudson Engineers performed underwater inspection of the ship dock and found the ship dock required extensive repairs. A feasibility study was prepared to determine the most economical means of rehabilitating the dock while keeping the crude oil dock in service. The scope of service included federal and state permit applications, construction documents for a new approachway, mooring and breasting dolphins, walkways, loading platform and demolition of existing structures. Hudson is ensuring that the installation of temporary walkways and product piping supports, construction of a new steel pipe pile-supported concrete approachway, and partial demolition of the existing timber low deck structure was in accordance with specifications. Construction is ongoing—four (4) new steel pile-supported reinforced concrete mooring dolphins have been completed in August 2007. The complete rehabilitation of the ship dock is anticipated to be the end of 2008.
Construction of a Trotter Racetrack over the Delaware River
Location: Chester, Pennsylvania
 Harrah's Chester Casino and Racetrack proposed to build a trotter racetrack on their Chester, PA facility. since the land was too small to fit the racetrack on the parcel of land, the track was proposed to go out over the Delaware River. S. T. Hudson Engineers' scope of services included a geotechnical investigation, federal and state permit applications, preparation of construction documents, construction inspection and "as-built" drawings. Hudson provided construction management for the demolition of existing structures, drilling of steel piles into the mica-schist, installation of the concrete deck, concrete retaining walls and steel sheet pile bulkhead.
The project required extensive pile-supported falsework since the project site had no soil
overburden about the rock.
Mooring and Breasting Facilities for the Trump Yacht "Princess" & Repair of Bulkhead and Dredging at Senator Frank S. Farley State Marina
Location: Atlantic City, New Jersey • Clam Creek
S. T. Hudson Engineers designed the facilities for berthing this 1,800 DWT vessel in the Frank S. Farley State Marina, adjacent to the Trump Marina Hotel and Casino in Atlantic City. Construction was scheduled on a fast-track basis. The work included permitting for dredging a deeper channel for the 282 ft. LOA, 15.4 ft. draft luxury yacht, and project construction management.
Additionally, Hudson conducted a diver/engineer survey of 1,700 L.F. of deteriorated timber bulkhead, identifying areas of material degradation, marine borer activity and structural failure. We performed stability analyses, then developed both a design for short-term repair of 400 linear feet of bulkhead for immediate implementation, and a design for long-term rehabilitation.
Hudson's scope included pre- and post-dredge soundings, volume calculations, sediment sampling and analysis, permitting for both, bulkhead repairs and maintenance dredging, and construction management.
