For years, Geotechnology has been helping protect structures and reduce its clients’ liability related to vibrations from construction, demolition, or other industrial activities by performing precondition surveys and vibration monitoring services. Historically, vibration monitors have required ample space for setup, a well-founded protective system from the always chaotic construction or industrial environment, and plenty of “baby-sitting” hours for instrument setup, maintenance and data downloading. For these reasons, we are excited to have recently enhanced our vibration monitoring capabilities with
the use of a wireless and internet-
based vibration monitoring network.
The vibration monitors provide automated, wireless transmission of data to Geotechnology via the INFRA Net website which saves time and enhances productivity throughout the duration of each project. The vibration monitors are compact, waterproof, and portable, each containing a geophone, datalogger, and communications capabilities. The small size of the vibration monitors makes them easy to mount on structures or couple to the ground in relatively out-of-the-way places with no wires to get in the way. The web-based software allows us to remotely set up, program and track the status of vibration monitors. The monitors send out immediate automatic notifications via text or email to assigned contacts at Geotechnology, Inc. in addition to the owner, project manager, etc., if a pre-assigned vibration threshold is exceeded. Also, recorded maximums can be plotted and analyzed over a pre-set time interval. Waveforms can be analyzed and reported immediately upon collection and without being on site. The internet-based system has allowed Geotechnology to provide more responsive vibration monitoring results with less effort and cost.

The need for special inspections and qualified Special Inspectors is continuing to grow, driven by the desire to enhance public safety and verify that critical structural components of the building are properly constructed. Increasingly, municipalities and design engineers are required to satisfy the special inspection requirements included in chapter 17 of the International Building Code (IBC).
Geotechnology’s Construction Materials Testing Group (CMT) includes qualified trained staff to perform special inspections. Our CMT field representatives are certified by International Code Council (ICC), American Concrete Institute (ACI), Post-Tensioning Institute (PTI), American Society for Non-Destructive Testing (ASNT), American Welding Society (AWS), National Concrete Masonry Association (NCMA), and National Institute for Certification of Engineering Technologies (NICET). Some of Geotechnology’s field representatives hold multiple certifications.
Special inspections are typically required for structural components of the building including the supporting soil, deep and shallow foundations, wood framing, concrete, reinforcing steel, masonry, structural steel, fireproofing, and exterior insulation and finishing systems (EIFS).
The design professional in charge is responsible for identifying specific components that require special inspection and incorporates a statement of required special inspections into the project documents. Those may include continuous and/or periodic inspections, depending on the item of work.
Geotechnology’s special inspectors then perform the tests and/or observations, issue electronic reports, and prepare periodic summary reports of our findings. If necessary, a deficiency punch list is generated. At project completion, we often prepare a final report, which includes the results of our observations and materials testing.
