Construction update

During the week of September 7th, the contractor completed the excavation for the control vault. The placing of concrete for the control vault foundation and the sheeting for the pump station will begin next week. The excavation for the pump station will begin following this work and is expected to last for approximately three 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 and continues.

 

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. The contractor completed excavation for the control vault and is planning to begin to drive sheeting for the pump station. The contractor has completed the relocations for the water line, storm drain, and force main.
As of September 11th, a number of submittals have been approved or are close to approval. These are:

  • Storm drain relocation
  • Force main relocation
  • Process piping for pumping equipment
  • Reinforcing steel for transition vault
  • Reinforcing steel for pump station
  • Storm drain relocation
  • Electrical wiring and grounding
  • Dust control plan
  • Soil sampling plan for pump station
  • Waterproofing
  • Dewatering plan

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 September 11th, these activities will include:

  • The contractor will be installing the reinforcing steel for the foundation slab. The first foundation placement for the control vault will be completed within the next week.
  • The concrete form work and placements will continue for the control vault walls.
  • The contractor is continuing the utility relocations to allow the construction of the pump station.
  • 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 begin the sheeting for the 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 LSRP air monitoring program continues in place.

The following new submittals are being reviewed by NHSA engineers:

  • Site utility relocations
  • Process piping
  • Process valves and operators

LSPR update

The Licensed Site Remediation Professional's (LSRP's) recent activities include:

  • Air monitoring of the site began on Thursday, August 27th and continues, in accordance with the LSRP-approved plan.
  • The air monitoring readings are continuing and 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 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 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.

Effect on local businesses

 

Sidewalk access permits unimpeded foot traffic to local businesses.

Traffic controls at site will minimize business impact.

Drop-off point will be maintained during construction.

Parking access may have
limited effect.

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.
