Construction Monitoring Services
in NYC & the Tri-State Area
Let’s Build The Future Together
Construction Monitoring & Surveying Services for NYC Developers, Engineers & Project Managers
We save people’s lives through vibrations!”, that’s how we describe what we do. By installing vibration monitors in buildings, subway tunnels, and structures adjacent to active construction sites, Saltus ensures construction-induced vibrations stay within safe limits, protecting the structural integrity of surrounding properties across New York City.
Beyond vibration monitoring, Saltus provides a full range of construction monitoring services and documentation solutions, including optical structural surveying, existing conditions documentation, crack gauge monitoring, wireless tilt meter monitoring, piezometers, and video caisson inspections. This comprehensive approach strengthens risk management, reduces legal exposure, and delivers peace of mind for clients throughout New York City and the Tri-State Area.
Frequently Asked Questions
The primary regulation driving our clients' monitoring requirements is NYC Building Code (BC) Section 3309 (Protection of Adjoining Property), which requires any person performing construction or demolition to protect adjoining structures from damage and implement comprehensive monitoring for movement, vibrations, and foundation settlement. While TPPN 10/88 governs historic properties, we also 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 is a direct cost. Because Saltus is headquartered in Manhattan, we can mobilize within 24 hours for emergency situations; installing compliant monitoring equipment and generating 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.
