Providing First-Rate Documentation and Construction Monitoring Services to the Tri-State Area and Beyond!
“We save people’s lives through vibrations!” That’s our go-to response when asked what we do. By installing vibration monitors in buildings, subway tunnels, and structures near construction sites, we ensure that vibrations from construction activities stay within safe limits, protecting the integrity of surrounding buildings.
But it doesn’t stop there. Alongside vibration monitoring, we provide a full range of documentation and construction monitoring services, including optical structural surveying, existing conditions documentation, crack gauge monitoring, tiltmeter monitoring, piezometers, and video caisson inspections. Our comprehensive services enhance risk management, help reduce legal costs, and provide peace of mind for our clients.
Frequently Asked Questions
While TPPN 10/88 is the baseline for historic properties, the primary regulation driving our clients' monitoring needs is NYC Building Code (BC) Section 3309 (Protection of Adjoining Property). Under BC 3309, any person performing construction or demolition must ensure adjoining structures are protected from damage and implement comprehensive monitoring for movement, vibrations, and foundation settlement. Additionally, we ensure compliance with MTA/NYCTA guidelines for transit-adjacent projects and NYC DEP Section 24-146 for air quality and dust mitigation.
When a Stop Work Order is issued, every hour of downtime costs you money. Because we are headquartered in Manhattan, Saltus can mobilize within 24 hours for emergency situations to get compliant monitoring equipment installed and generate the defensible data the DOB requires to lift the SWO.
Engineers of Record (EORs) and transit authorities typically demand strict accuracy tolerances down to 0.1 millimeters. To meet these rigorous demands, we deploy Automated Motorized Total Stations (AMTS) and high-fidelity crack gauges that provide sub-millimeter precision, ensuring micro-movements are detected long before they reach critical thresholds.
Clients get 24/7 access to a real-time web dashboard with automated SMS and email alerts triggered the exact moment a vibration or dust threshold is exceeded. For the DOB, MTA, and project engineers, we also provide formalized, defensible PDF reports to prove continuous regulatory compliance.
We work with your site team to determine the best setup. Depending on the site logistics, we can use hardwired 110V AC power, or rely on our remote, self-sufficient options like solar panels and extended battery backups so we don't interrupt your site power.
While the industry standard is usually one to two weeks, Saltus stands out by dramatically compressing this timeline. For urgent projects, our agile field teams have successfully installed full monitoring systems within 24 hours of the client's initial outreach.
We mitigate false alarms by using highly calibrated seismographs and correct sensor coupling methods. Additionally, our manned vibration monitoring services place a skilled technician on-site who can instantly differentiate between ambient urban noise (like a passing garbage truck) and actual construction-induced vibrations.
Securing neighbor access is historically the biggest hurdle in urban construction. Saltus alleviates this by acting as a professional, independent third party. We prioritize clean, minimally invasive installations, getting in and out swiftly to satisfy access agreements without adding friction to the project.
