Role: Provide a full campaign of Monitoring services for 1-2 Years

A new series of street-level and aerial renderings have been revealed for The Alloy Block, a two-tower mixed- use development designed and developed by Alloy Development and located at 80 Flatbush Avenue and 100 Flatbush Avenue on the border of Downtown Brooklyn and Boerum Hill. Renderings depict the 482-foot-tall 100 Flatbush Avenue, a 44-story edifice being built in phase one at the corner of Flatbush Avenue and State Street, which will be the city’s first all-electric tower.

The design consists of a triangular superstructure that will yield 440 rentable apartments and 30,000 square feet of ground-floor retail with 350 feet of frontage facing Flatbush Avenue. Phase two will include 80 Flatbush Avenue, an 840-foot-tall residential, office, and retail tower. The project is being developed in conjunction with the New York City Educational Construction Fund and will feature New York City’s first two passive house schools, the Khalil Gibran International Academy (KGIA) high school and a 500-seat elementary school. The public schools will meet the highest standards of energy efficiency and indoor air quality.

Role: Documentation of 1 million sq ft of existing structure

Hudson Yards has changed the city’s iconic skyline. Unprecedented and ongoing investment marks Hudson Yards as the nation’s largest private development, and one of the most complex construction projects in the history of New York.

Constructed on 28- acres over a working rail yard, two “platforms” bridge over 30 active train tracks, three rail tunnels and the new Gateway Tunnel.

300 caissons support the platforms and buildings. The caissons (four to five feet in diameter and 20 to 80 feet in depth) are drilled deep into the bedrock between existing tracks. Finished towers extend from the caisson foundations, through the platforms, and then rise skyward. This eastern portion of the platform used 25,000 tons of steel, 14,000 cubic yards of concrete and weighs more than 35,000 tons.

Caisson drilling began in March 2014 and the platform was completed the following year. Throughout construction the trains have remained operational, and the new No. 7 subway extension opened at Hudson Yards in 2015.

GEOTECHNICAL INSTRUMENTATION AND MONITORING PLATTSBURGH (SARANAC STREET) FORMER MGP SITE

As part of our ongoing partnership with NYSEG, we were tasked with providing geotechnical instrumentation and monitoring services for the former Saranac Street MGP Site in Plattsburgh. Our team worked closely with NYSEG to develop a comprehensive plan to monitor ground vibrations during construction activities at the site.

The goal of this project was to ensure that all construction activities would not cause any adverse effects on nearby structures or utilities. This was especially important given the sensitive nature of the former MGP site and its potential impact on the surrounding community.

Our team installed a network of vibration sensors around the perimeter of the site to measure ground vibrations in real-time. These sensors were also connected to an automated system that allowed us to remotely monitor data and receive alerts if

Schedule/Budget Management | Vanguard was required to inspect 250 manholes before the end of October 2024. By efficiently managing the workload, they were able to finish all inspections in only two weeks.  With regards to the schedule and budget, there were no challenges for the schedule or budget. 

Quality Management | The quality of the report was overseen by the President of Vanguard to make sure all was included in the report. There were no challenges. 

Stakeholder Input | Stakeholder input played a vital role in the successful execution of the Vanguard Ryebrook manhole inspection project. Working closely with the town of Rye Brook, Vanguard ensured that the project was aligned with the town’s requirements and environmental goals. The town needed detailed and accurate manhole inspection data to demonstrate compliance with environmental regulations and to prove that their infrastructure did not contribute to the contamination of the Long Island Sound. By maintaining open lines of communication and involving town representatives in scheduling and flagging operations, Vanguard was able to efficiently coordinate daily activities and minimize disruptions to the local community. The collaborative effort not only facilitated timely completion of the inspections but also guaranteed that the resultant reports met the stringent standards required by the environmental group overseeing the project. This comprehensive engagement with stakeholders underscored Vanguard’s commitment to transparency, accuracy, and community-focused service delivery.

Innovation | Key innovations included the use of the Envirosight 360-degree Lidar Camera paired with WinCan software. This combination allowed precise and detailed inspections, capturing high-resolution images and videos that revealed structural defects, service lateral locations, and signs of Infiltration & Inflow (I&I). The unique delivery of the final report through an electronic link to the client’s project platform within the software streamlined the review process, ensuring quick and easy access to inspection data. The integration of advanced lighting and centering techniques further enhanced the quality of the inspections, while a systematic approach involving a field technician for on-site data collection and an administrator for report compilation ensured efficient project execution. The meticulous oversight by the company president guaranteed the highest quality standards were met, reflecting Vanguard’s commitment to excellence in the public water sector. These innovations not only facilitated the timely completion of the project but also provided valuable insights that will benefit future collaborations with DDC.
