OZA consults several construction companies, mining operations, blasters and members of the public on a regular basis. Since 1976, OZA and its personnel have been carrying out pre / post condition surveys which include a detailed documentation of the interior and exterior conditions of man-made structures in proximity to construction and mining activities. OZA inspects thousands of surface and subsurface structures annually. Some of the personnel have experience dating back to the late 1950's. OZA also performs monitoring for these structures

MONITORING Once your project is underway, OZA can provide on-going vibration monitoring of surrounding structures. We have developed and use the latest in seismograph technology - the new OZA IV and its predecessors the GPS-3 and CVM-2 monitoring units. As blasters and contractors require instant feedback, we can provide instant blast and vibration information using our latest software and hardware capabilities with the highest reliability and accuracy. Our vibration and noise experts can provide you with the support you need. 

Pre-Blast or Pre-Construction Surveys Many unwarranted damage claims can be eliminated by the performance of detailed pre-blast surveys. Expensive damage investigations and potential litigation can be largely avoided with photographic documentation of the pre-existing conditions of structures around a site.

​ Damage Assessments Damage assessments are conducted by a professional senior consultant who arrives at a conclusion about damage probability. We have performed these investigations for major insurance carriers, law firms, companies and individuals.

​ Professional Services In the event it becomes necessary, data review, pre-trial preparation and expert testimony concerning the effects of vibrations can be provided by our senior consultants.
