In New York, including New York City, Westchester, Rockland, The Hudson Valley, and all of Upstate, Hartford Structural Inspections (HSI)  provides all necessary protection and documentation services for all Contractors in the Construction and Excavating businesses.  If you are preparing for a new building, pipeline, utilities, or general construction work, we are there for you. We make sure you are protected by documenting the area and buildings whether it be before , during, or after your work. We  measure vibration on short term or long term projects in person using WIRELESS SEISMOGRAPHS.

Pre Blast & Pre Construction Surveys in NEW YORK

For 18 years, we have been performing high definition video pre blast / pre construction surveys. By having all surfaces fully documented for p
re existing conditions; if there is a claim of damage, all parties are protected. All surfaces are surveyed, a technician uses LED light to illuminate defects that are hidden in ambient light. All damages are highlighted using a laser pointer. Structural and cosmetic damages and defects and also described audibly by the video technician. We have extensive experience documenting private homes and apartments, and commercial buildings of all sizes. We have surveyed Dams, utilities, fields, parking lots, haul routes, and other various structures adjacent to work sites. CRACK GAUGES can also be installed and to be checked regularly.

Vibration, Sound, Crack and Optical Settlement Monitoring in NEW YORK

HSI monitors and records all Vibration that is produced from blasting, construction, and all vibratory work sources  Timely feedback to contractors mitigates the possibility of creating vibrations high enough to cause damage to neighboring structures. We also monitor utility lines and pipelines. 

We utilize Seismographs by Instantel, Geosonics, Thomas Instruments and Nomis. We offer supervised or Wireless (Remote) Monitoring which 
is now growing to reduce costs and to maintain 24 hour coverage and reporting. HSI deploys dozens of remote seismographs in long term and short term projects. To meet your needs, these units can be mounted inside any structure or outside with a Solar Panel. Sound Monitoring is also performed on site manned or remotely.
