Construction update

The contractor has begun in earnest the deep excavations for the project and will continue to work within the control vault, emergency generator and pump station work areas in the coming two weeks. The contractor continues to work on utility relocation submittals and plans. Air monitoring of the site, as directed by the LSRP, began on August 27th. Because of the excavation activity, the contractor will need to make a short-term, two day change in the traffic flow next week (see below, “Coming up” for details).


As shown 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.

Latest construction activity

Over the past week additional submittals from the contractor continued to be reviewed and processed by NHSA engineers. In addition, the contractor recently completed the test pit for the existing outfall to obtain information on its location and exact depth.
As of August 28th, a number of submittals have been approved or are close to approval. They are:

  • Process piping for pumping equipment
  • Excavation support plan for control vault (sheeting)
  • Reinforcing steel for transition vault
  • Reinforcing steel for pump station
  • Test pits
  • Storm drain relocation
  • Electrical wiring and grounding
  • Dust control plan
  • Soil sampling plan for pump station
  • Waterproofing
  • Dewatering plan

As discussed in previous week’s newsletters:

  • Sheeting is continuing and excavation activities have begun at the control vault.
  • The traffic control plan has been approved and the mobilization of the detours around construction has occurred.
  • The preparation of the island for the construction phase was completed.
  • The width of road lanes around the site was checked, and it was confirmed that the existing 12 foot width allows the passage of emergency vehicles, as per the approval of the Hoboken Police Department.

Coming up

In the next two (2) weeks the contractor will continue to prepare submittals and obtain approvals for construction activities. Going forward into the week of August 31st, these activities will include:

  • The contractor has been excavating in the location of control vault. The excavation will continue through Monday and Tuesday of next week. As the work goes deeper at the control vault, a different type excavator than the one currently in use must be employed. This was not foreseen by the contractor. The new excavator has a full radius swing on its arm. This radius swing reaches out into the eastbound lane of 11th Street between Hudson Street and Maxwell Lane. Because of this, on Monday and Tuesday (August 31st – September 1st) from 8:00 a.m. to 4:30 p.m., there will be intermittent road closures on 11th Street between Hudson Street and Maxwell Lane. (See map below).

  • The contractor will continue tests pits for site utilities. The utility relocation work will require coordination with the Hoboken Police and notification of the Maxwell House Homeowners Association (HOA) in advance of the tie-ins. The engineer will obtain at least a 72 hour notice for any temporary street closures for utility tie-ins and will give the HOA as much notification as possible. As always, streets will continue to be passable for residents and emergency vehicles. Tie-ins will be made as quickly as possible once they have been approved for installation.
  • The contractor will continue the sheeting for the control vault area and begin the sheeting for the pump station.
  • The contractor will continue the excavation work for the control vault, which is short of the disturbance of engineered cap.
  • The contractor will have a water truck available to abate dust and soil an erosion controls to prevent the migration of dust from the construction area.
  • The LSRP air monitoring program was completed and shared with the HOA and the City of Hoboken during the past week.

The following new submittals are being reviewed by NHSA engineers:

  • Soils disposal plan and required forms
  • Process piping
  • Process valves and operators
  • Monitoring plans and schedule of values

LSPR update

The LSRP’s recent activities include:

  • The approval of the dust control plan for the project. The dust control plan is designed to prevent dust migration from the construction area.
  • Notification to the NJDEP, the HOA, and the Site LSRP of Record of the impending disturbance of the engineered controls (the environmental cap).
  • The air monitoring plan was completed and shared with the HOA and the City of Hoboken.
  • Air monitoring of the site began on Thursday, August 27th.
  • The air monitoring readings thus far this week showed that no LSRP-established monitoring limits were exceeded.

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 the emergency generator on North Hudson’s existing 11th Street pump station island between Hudson and Washington Streets, as well as beginning work on the control vault and new H-5 WWPS.
  • LSRP monitoring begins with construction and ends when the cap is restored.
  • Control vault construction continues until April 2016.
  • Pump station construction continues until August 2016.
  • Final completion and site restoration is scheduled for October 2016.

Role of the LSRP

The Licensed Site Remediation Professional (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 for August 27th is being uploaded to 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.
