Vibration Monitoring and Geo-Structural Consulting
Distinct Engineering Solutions, Inc., (DESI) incorporates science and technology into the design and installation of monitoring instruments. These services are routinely provided to protect and document that assets are not damaged during any nearby construction activities. Our Structural, Geotechnical and Environmental Instrumentation Services provide data that help engineers in every stage of a project ensure the quality of life is maintained and not compromised.
We specialize in delivering managed monitoring solutions, customized to your exact specifications. Based on our ex
tensive experience, we will guide you through your design options to help you select the most appropriate system, highlighting the differences between various monitoring methods, as well as the cost implications. We provide our clients with experienced monitoring engineers for the duration of a project, on a full or part-time basis.
We also provide automated monitoring systems. These typically involve data being collected through cellular or GPS connections. Data can be transmitted to a web-based monitoring system which allows for easy handling of complex data.
Our instrumentation services include:
- Deformation Monitoring
- Monitoring System Design and Integration
- Pore Pressure Measurements
- Pre- and Post- Construction Survey
- Real-time Groundwater Monitoring
- Remote Video Surveillance
- Settlement Monitoring through Survey or Automated Total Stations
- Stress Monitoring
- Tilt Monitoring
- Vibration Monitoring
- Web-Based Remote Monitoring System Development
Reconstruction of Belt Parkway Bridges Project
NYCDOT contracted with Tully Posillico Joint Venture (TPJV) to complete the demolition and reconstruction of three new bridges. The project would incorporate demolition and complete reconstruction of the Paerdegat, Rockaway, and Fresh Creek bridges. DESI was retained by TPJV to develop a Geotechnical Instrumentation and Monitoring Plan. Using a unique automated monitoring technique that sends real-time alarms and notifications to project engineers corrective actions could be taken almost immediately. DESI installed prisms, tilt meters, seismographs and piezometers to monitor ground and structural settlement, tilt and vibrations, and groundwater levels; and provided weekly and monthly reports. DESI’s approach helped the client to reduce the construction duration by 6 months.

#7 Subway Line Extension Site K
MTACC has undertaken the project of extending the #7 Subway Line along the west side of Manhattan. The MTA retained Scalamandre Oliveira JV (SOJV) for construction of the Ventilation Building and Reconstruction of 11th Avenue and West 36th Street at Site K. DESI developed the Structural Monitoring and Noise Control Plans, installed real-time monitoring equipment on the adjacent Jacob Javits Center, performed baseline noise/air/vibration monitoring and developed site-specific limits and submitted weekly and monthly reports.

Pelham Former MGP Site, Corrective Action Project
Posillico Environmental was retained by ConEdison to perform remedial action at the former Pelham MGP site in Pelham, Westchester County, NY. Remedial action required the construction of a jet-grout barrier wall underneath the existing sheet pile barrier wall that enclosed the site. The jet-grout barrier wall was extended from the tip of the sheet pile wall to the top of bedrock. DESI developed a Structural Instrumentation and Monitoring Plan for the gas main pipe and trestle structure and utilized an automated monitoring system that sent real-time alarms and notifications to project engineers.
Metro North Railroad Embankment Structural Monitoring
Kiewit Infrastructure Company (Kiewit) was retained by Metro North Railroad to stabilize an embankment along the Hudson Line, where tracks sit on a thin, rocky ledge in the region just north of Peekskill, NY. DESI provided Kiewit with services to furnish, install, maintain and monitor instrumentation through-out the duration of construction. Using settlement monitoring points and In-Place Inclinometers, as well as a Web-Camera to monitor construction, DESI successfully implemented the complex real-time monitoring system to provide timely warnings and help Kiewit avoid construction delays.
