Environmental Testing & Remediation for Child Care Center, Federal Building

The General Services Administration (GSA) retained Tectonic to provide environmental testing and remediation services. Building restoration work caused Poly-Chlorinated Biphenyl (PCB) -laden debris (from waste caulk) to fall throughout the Federal courthouse plaza and playground of the employee’s day care center. This project had a sensitive population at risk and the falling debris resulted in site-wide contamination above background levels with both state and Federal regulatory triggers.

  • Review, test, and evaluate extent of residual PCBs.
  • Remedial Investigation (RI)
  • Delineated and managed remediation of the PCBs .
  • Regulatory framework included satisfying New Jersey Department of Environmental Protection
    (NJDEP) and Federal Toxic Substances Control Act (TSCA) requirements simultaneously.

The site is within a large city; this, and the security issues made the Remedial Investigation a challenge.

Central Park Police Precinct Soil Investigation

Remediation of an existing landmark police precinct building in Central Park. Three leaking underground storage tanks (USTs) were located on the property, adjacent to the existing building, which resulted in petroleum contamination of soils under and adjacent to the building.

A remedial investigation was performed in the building footprint to delineate petroleum impacted soils using shallow test pits, organic vapor screening and soil/groundwater sampling  accordance with NYSDEC DER-10.  A remedial investigation report was prepared including sampling methodology, test pit logs, data analysis, conclusions and remedial alternatives.  An indoor air assessment was conducted with an underslab vapor collection system and SVE remediation system designed and installed.

Tectonic worked with NYCDDC to get NYSDEC approval during these conditions discovered during construction to avoid project delays, remove several feet of petroleum-impacted soils, and address potential vapor intrusion to impacts future occupants.

The project received the following awards: 2013 ACEC Gold Award; 2012 Lucy Moses Award for outstanding preservation efforts; and 2010 ACEC Platinum Award to Tectonic for innovative design of a below grade SVE remedial system minimizing visual effect.

GOSR Term Agreement for Environmental Review, Management and Testing

In October 2012, the largest storm surge in New York’s recorded history swept ashore. Hurricane Sandy’s effect was devastating, causing widespread damage to core infrastructure. NYS developed a Storm Recovery Plan that focused on meeting the immediate needs for housing and business assistance through HUD in the form of CDBG-DR funding for the immediate acquisition of properties and relief of affected residents through a voluntary buyout program. Tectonic has been providing environmental services for homes and small businesses in State Island and Upstate New York that have been included in the Governor’s Office of Storm Recovery’s programs under a two year agreement with a one year extension. Resiliency, repair & reconstruction as well as buyout programs are some of the exciting projects Tectonic has been involved with and continue to work on.

As part of the contract, Tectonic completed environmental review services for the program and demolition of nearly 500 homes in the Oakwood Beach area of Staten Island known as the Oakwood Beach Buyout Program. Tectonic has provided full Type 1 action services under SEQR, including: preparation of a Full Environmental Assessment Form (LEAF), Coast Consistency Assessment, Phase 1 Environmental Assessment, HUD Environmental Assessment NEPA Checklist and the 8-Step public noticing and comment process for Floodplain Management Plan and FONSI.

Solar Rooftop Installation Design at Cornell Bloomberg Building Cornell Tech’s Roosevelt Island Campus Construction

This project included the construction of a new Cornell Tech campus including two million square feet of state-of-the-art buildings, over two acres of open space that will become home to over 2,000 graduate students and hundreds of faculty. The construction included the installation of solar panels on the Bloomberg Center and Bridge building. When completed, the 12-acre campus will be known as one of the most environmentally friendly and energy efficient campuses worldwide. Tectonic provided engineering services for the installation of a rooftop solar system at the Bloomberg Center Building and Bridge Building.

Tectonic performed structural analysis and design of the proposed solar mounting steel support system. The support system for Bloomberg was composed of steel members and Unirac rails and the Bridge building was composed of Unirac rails at an 8-degree tilt. The design included a design to span the large 25’ and 30’ spans as required to support the PV panels. Tectonic also drafted structural design drawings and was involved with the permitting process with the NYC DOB.
