Construction update

Work continues to progress on schedule. On August 1, the pump station’s electrical power was installed. The contractor is planning the remaining work on the transition (Tideflex) valve chamber (this is the large red valve that will be installed below grade).


The following are recent activities:

  • Site—PSE&G powered the new transformer located at the 11th Street pump station which allows the pumps and control vault equipment to be tested.
  • Pump station—The contractor is preparing for electrical and mechanical testing of the pump station. The instrumentation and controls for the pump station will be tested followed by the pumps. This will occur during dry weather.
  • Transition vault—Nearing completion on the transition vault, the contractor is working on the mechanical piping and control valves to allow the pumps to be tested. (See previous newsletters for diagram and explanation of the transition vault area.)
  • Control vault—The contractor has energized the control vault and begun preparations for testing the equipment and the functionality of the controls. The switchgear, variable frequency drives (which control the speed of the pumps), small transformer inside the vault, automatic transfer switch (the switch allows power transfer to emergency generator during a power outage), main control panel, sump pump control panel, and circuit breaker panel within the structure are being checked and tested.
  • Emergency generator—The contractor completed the installation of the emergency generator on NHSA’s 11th Street island west of Hudson Street and will test the generator now that the new pumps are energized.
  • Restoration/landscape planning—The combined NHSA-Maxwell HOA working group met for the first time on August 3rd to begin planning for the restoration of the Maxwell islands. A preliminary plan was discussed and HOA representatives’ feedback was incorporated. A second iteration of the plan will be discussed at the next working group meeting in two weeks. The landscape architect chosen by NHSA, Melillo + Bauer Associates, is the same one that originally designed the landscapes for the Maxwell development.
As illustrated in previous newsletters, the project’s three (3) phases are dictated by the engineering and construction requirements and will occur in three areas along 11th Street, as seen in the figure below. The three phases are: 1) the construction of the wet weather pump station; 2) the construction of the control vault; and 3) the installation of the emergency generator.

Coming up

In the next two (2) weeks, the contractor will complete submittals, obtain approvals for construction activities and begin functional testing of the equipment. Going forward into the week of August 15th, these activities will include:

  • Transition vault—Continue the preparation for the construction of the concrete walls and the installation of the tideflex valve.
  • Pump station—Functional test the main pumps.
  • Control vault—Functional test the equipment and controls.
  • Site—Complete the sitework around the transformer to the west of the Authority’s 11th Street pump station.
  • The contractor will continue to have a water truck available to abate dust and soil an erosion controls to prevent the migration of dust from the construction area.
  • The landscape architect will meet with NHSA and representatives of the HOA to initiate planning for the restoration of the Maxwell island.
  • The Licensed Site Remediation Professional (LSRP) air monitoring program continues in place.

LSPR update

The LSRP’s recent activities include:

  • Air monitoring of the site began on Thursday, August 27th, 2015 and continues, in accordance with the LSRP-approved plan.
  • The air monitoring readings are continuing. Daily updates are being sent to the HOA and the weekly updates are being posted on the NHSA website.

Overall construction schedule

The current overall construction schedule remains as follows:

  • Pre-construction activities—Completed as scheduled.
  • Construction activities, now underway—Mid-August through December. This includes work on the installation of control vault and pump station. The emergency generator on North Hudson’s existing 11th Street pump station island between Hudson and Washington Streets will also be constructed once the transformer and generator are procured.
  • LSRP monitoring begins with construction and ends when the cap is restored.
  • Control vault construction continues through April 2016. Control vault electrical continues through June 2016. Functional testing in August 2016.
  • Pump station testing continues through August 2016. Functional testing continues until early September. Transition vault construction continues following functional testing.
  • Final completion and site restoration is scheduled for October 2016.

Role of the LSRP

The LSRP serves an extremely important function in the construction of the H-5 WWPS. He will oversee all environmental issues on the site, including the voluntary air monitoring that North Hudson is undertaking. In this capacity, the LSRP is responsible to the NJDEP for ensuring that all construction is done in accordance with the Remedial Action Plan filed with the State during the original development of Maxwell Place. The contractors will take no steps that impact the environment without the strict oversight of the LSRP. The LSRP will report on a regular basis to the NJDEP.


Because Maxwell Place was constructed on land that was remediated for soil and groundwater contamination, an NJDEP-approved engineered cap was placed within the development and along 11th Street. The construction of the WWPS will lift minimal parts of the cap in carefully defined areas, and the LSRP will develop a Data Collection Plan to strictly supervise and control all related construction activities. No construction that impacts the existing cap can be undertaken without the approval of the LSRP.


The LSRP will also supervise the gathering of air samples adjacent to the construction, as part of North Hudson’s voluntary air monitoring program. The LSRP will oversee the air quality data collection and provide advice before construction begins, during excavation and until the cap is replaced.


The recent air monitoring data can be found on the NHSA website.

Air monitoring

Although the NJDEP does not require air monitoring for the H-5 WWPS project, North Hudson is voluntarily monitoring the air surrounding the construction site for dust and volatile organic compounds (VOCs). The LSRP will continuously monitor the air during excavation activities and until the original cap has been replaced. This is a relatively conservative approach, as it is designed to alert the construction team whenever dust is in excess of the LSRP monitoring plan. Readings that show elevated levels of dust or VOCs in the air will result in review and remedial action to abate the condition as approved by the LSRP. Our e-newsletter will provide regular summaries of the air monitoring activities, and the website (nhudsonsa.com) will post daily readings.
