ZoneCheck® Construction Vibration
Estimating ground vibration distance just got easier
Travelers’ online construction vibration tool, ZoneCheck, is designed to help you identify potential [equipment-generated] ground vibration risks. With it you can complete preconstruction project surveys in real time, either on the jobsite or from your office.
ZoneCheck conveniently centralizes industry-recognized ground vibration data for construction equipment by soil types. The resulting calculations indicate how far ground vibrations can extend to surrounding structures or people. ZoneCheck also helps you document preconstruction evaluations that can be easily shared electronically.

SPEAKER 1: You already know all about how ground vibration can cause damage to surrounding structures.
And you're probably aware of that can cause serious profit losses to your job. What you might not know is that
Travelers has developed an online tool designed to help introducing Travelers ZoneCheck.
It's a convenient way to help predict vibration distance. In just a few clicks, it can eliminate guesswork and help
you to identify potential losses. Enter a few inputs for the job at hand and then let ZoneCheck make an
assessment. It can help in areas where you might logically anticipate a problem, but more importantly in areas
that are farther away, where you're less likely to expect issues to occur. Use ZoneCheck to help identify
construction vibration influence zones, so that appropriate measures can be taken to safely execute your work.

Use ZoneCheck to:
- Establish or refine your strategy for pre-construction surveys
- Estimate the potential for ground vibration to impact nearby structures or be perceived by occupants
- Develop measures to help mitigate against damages caused by vibration generating work
Use of construction equipment can create ground vibrations potentially impacting surrounding structures, therefore, understanding the potential risk of property damage is an important aspect of preconstruction surveys.
ZoneCheck develops two radii from the source; the “alert zone” and the “human perception zone”. The “alert zone” is closer to the vibration source. Structures within this zone should receive a higher degree of analysis/review and include photos documenting exterior building conditions and, where appropriate, interior photos. In certain situations, seismographs may need to be positioned in key areas to document the levels of ground vibrations, and construction methods may need to be altered to protect more sensitive structures. In the outer radius, the “human perception zone”, vibrations are likely to be perceived by occupants but less likely to result in structural building damage. Understanding the human perception zone and following appropriate measures can prepare you in the event occupants perceive vibrations and allege damages.
Once you input the equipment and soil type into ZoneCheck, an aerial image of your project site/area is generated that includes both “zones” of influence and their distances. This information can help you further develop mitigation plans specific to the type of work underway.
ZoneCheck can also produce documentation you can share with other stakeholders at your project with the tap of a button. If allegations are made linking your work to property damage caused by ground vibration, these reports can help document steps taken before work starts, and potentially mitigate these exposures.
