Construction update

As last week’s newsletter (Volume III) pointed out, the construction of the H-5 Wet Weather Pump Station project is underway, with an approved traffic control plan in place and mobilization activities beginning in the next several weeks. (See sidebar for details on traffic control plan). The “Coming up” section below details the impending mobilization activities, several of which are scheduled to begin next week.

 

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 pre-construction activity

As outlined in last week’s newsletter (Volume III), during the pre-construction phase, the contractor has submitted to the engineer requests for approval for several important construction activities. Construction activities cannot commence until they are submitted to, and approved by, the engineer. The contractual timeframe for approval by the engineer is 21 days after submission by the contractor; however, the engineers have been instructed to target the completion of reviews within 14 days of submittal to keep the project moving along.

 

As of July 30, a number of submittals have been received by the engineer and are in the review and approval process. These are:

  • New Emergency Generator
  • Excavation Support Plan for Control Vault
  • Electrical Wiring and Grounding
  • Foundation Reinforcing Steel for Control Vault
  • Temporary Relocation of Existing Generator
  • Mobilization Plan

As previously reported, the traffic control plan (see sidebar for details) was approved by the Hoboken Police Department on July 16.


Coming up

In the next two (2) weeks the contractor will continue to prepare submittals and obtain approvals for construction activities. On July 24, the contractor mobilized the site along 11th Street at the control vault work area. (See map above).

 

Next week, the contractor is expected to mobilize at the pump station work area on the eastern side of 11th Street between Maxwell Lane and Sinatra Drive North. This will occupy the full width of the road beginning Wednesday, August 5, 2015. (See map above and the traffic control plans).  The erection of barricades and fencing in this area, including detour signage, will be part of this mobilization. In accordance with the traffic control plan, police details will be assigned to direct traffic during this period of mobilization.

 

The mobilization activities will include the following:

  1. Installation of Jersey barricade and fence in accordance with the approved traffic control plan.
  2. Removal of all island trees and shrubs and the curb within the fenced off construction area.
  3. Preparation of the area for construction activities and setup of sheeting activities.
  4. Mobilization of a construction trailer and submission of plans for temporary water and electrical during construction.
  5. Continue test pits for site utilities which will be coordinated with Hoboken Police Department.

Overall construction schedule

The current overall construction schedule remains as follows:

  • Pre-construction activities: Now to early August.
  • Construction begins: Early 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; and 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

As of July 30, the LSRP continues to prepare the air monitoring plan and is expected to submit it within the next week or so. The LSRP will be reviewing the soil samples from the geo-probes 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.

Sidewalk and auto access

The traffic control plan is now approved by the Hoboken Police Department as follows:
as follows:

 

Sidewalks

South sidewalk on 11th Street: Open at all times.

East sidewalk on Sinatra Drive North: Maintain drop-offs for school.

North sidewalk on 11th Street: Brief intervals of closure between Sinatra Drive North and Hudson Street.

East and West sidewalk at Maxwell Lane: Maintain access for drop-offs to daycare.

 

Traffic

 

Uninterrupted access to parking garage.

Eastbound traffic lanes 11th Street: Short temporary closures during utility relocation; both lanes closed during pump station construction between Maxwell Lane and Sinatra Drive North. Open at all times from Maxwell Street to Hudson Street.

Westbound traffic lanes 11th Street: Temporary closures for traffic relocation between Maxwell Lane and Hudson Street. Both lanes closed during pump station construction from Maxwell Lane to Sinatra Drive North.

 

Parking

 

No street parking during construction hours between Maxwell Lane and Hudson Street.

No street parking on 11th Street from Hudson Street to Sinatra Drive North (Eastbound).

 

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.

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.
