Construction update

The construction of the H-5 Wet Weather Pump Station project is now underway. The contractor has begun mobilization activities and will continue to progress the work within the control vault, emergency generator and pump station work areas in the coming two weeks (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

The contractor is advancing the work from the pre-construction phase into the construction phase. A significant number of submittals have been reviewed and approved in the past month. While the contractor will continue to make submittals on the project, the submittals that have been approved will allow him to advance the work and relocate utilities in 11th Street and within the barricaded areas.

 

As of August 7th a number of new submittals have been received by the engineer and are either approved of close to approval. These are:

  • Excavation Support Plan for Control Vault (Sheeting)
  • Electrical Wiring and Grounding
  • Foundation Reinforcing Steel for Control Vault
  • Temporary Relocation of Existing Generator
  • Dust Control Plan
  • Soil Sampling Plan
  • Waterproofing
  • Dewatering Plan

The traffic control plan has been approved and the mobilization of the detours around construction has occurred. The City of Hoboken agreed to allow a delay in the implementation of the bike lane project along Sinatra Blvd. until the H-5 project is substantially complete. This concession has enabled the implementation of the agreed-upon traffic control plan for H-5 without added complications.

 

During the past week, the contractor removed island trees and shrubs within the fenced-off construction area. NHSA had verbally agreed to look at the possibility of preserving and replanting the island trees. Therefore, before removing the trees, the contractor discussed with the City Department of Environmental Services the possibility of preserving the trees off-site and replanting them at the conclusion of the project. It was determined by the Department and its landscaping professionals that the expected survival rate of the trees (very low) and the cost of temporary preservation were significant impediments. The Department of Environmental Services consequently approved the cutting down of the trees which will be replaced with comparative trees when the project is completed. Smaller shrubs are, however, being preserved for replanting on the island whenever possible.


Coming up

In the next two (2) weeks the contractor will continue to prepare submittals and obtain approvals for construction activities.


The week of August 10th the contractor is planning to continue tests pits for site utilities and is planning to mobilize equipment for sheeting of the control vault area. 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. (See the update on the LSRP below.)

 

The contractor will continue construction activity along 11th Street:

  1. Install Jersey barricade and fence within the emergency generator area in accordance with the traffic control plan.
  2. Begin relocation of utilities within 11th Street. Several utilities will need to be relocated alongside and within the pump station and control vault work areas.
  3. Begin excavation activities for the control vault.

The following submittals are expected to be under review by the engineers:

  • The plan for the new generator slab at the 11th Street Pump Station site.
  • The plan for the reinforcing steel at the transition vault.
  • Submission of pumping equipment and electrical panels.

Overall construction schedule

The current overall construction schedule remains as follows:

  • Pre-construction activities: Expected to be completed in the first half of August.
  • Construction begins: Mid-August through December. This will include 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.

LSRP update

During the last week, the LSRP reviewed and approved the dust control plan for the project. The dust control plan is designed to prevent dust migration from the construction area. In addition, the LSRP continues to prepare the air monitoring plan and will calibrate the initial conditions onsite with air monitoring equipment. The LSRP has reviewed the soil samples from onsite, and he will factor this information into his plan. Once completed, the plan will be made available to the HOA and City of Hoboken. The plan is expected to be completed in the next two weeks.

Traffic controls at site will minimize business impact.

Drop-off point will be maintained during construction.

Parking access may have
limited effect.

Parking garage access remains in place.

Restrictions on street parking will be impacted during construction.

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.
