Monitoring Services
Chapter 33 requires monitoring whenever you excavate, blast, drill or demolish near an existing structure. We file the plan, install the instruments, hold the baselines and produce the record that protects you from a damage claim.
What we install
Wireless autonomous arrays where continuous coverage matters, attended manned monitoring where a person has to be there to make the call.
Continuous seismographs on adjacent structures through blasting, drilling, excavation, pile driving and demolition, with alert thresholds agreed before work starts.
Horizontal and vertical movement tracked to sub-millimetre precision using Automated Motorized Total Stations — required by Chapter 33 during excavation near existing structures.
Existing defects in adjacent buildings tracked from baseline through closeout, so movement that predates your work never becomes your liability.
Independent, defensible documentation of every structure adjacent to your site — completed before mobilisation and again after closeout.
Filing & compliance
We prepare and submit the monitoring plan to the DOB, coordinating with your engineer of record before anyone mobilises.
Points established, sensors mounted, baseline readings taken and locked before the first machine starts.
Daily, weekly or exceedance-triggered — formatted for the department and readable by your project team.
