Chris founded Revolutio in 2012 as a part-time endeavour while working as a consulting structural engineer, but the underlying work can be traced back to his time as an undergraduate at the University of Sydney in 2007. He has worked for Taylor Thomson Whitting, SCP Consulting and Opus International Consultants and was involved in a number of high-profile engineering projects across Oceania, such as retrofitting walkways to the Sydney Harbour Bridge, earthquake assessments in Christchurch, and developing a tablet-based structural inspection application for the Northwest Rail Link.

Topographic Multiplier (Mt) Detection Improvements
Until now, CHECKWIND has used a combination of the 500 m segment criteria from the AS/NZS 1170.2 commentary (though with a “rolling” 500 m segment instead of less accurate 500 m increments from the crest suggested by AS/NZS 1170.2), in addition to our own local minimum criteria to determine the base of a feature.
Figure 1: AS/NZS 1170.2 C4.4.2
However, the problem with utilising the local minimum criteria is that the base might be determined as being at the bottom of a valley with a steep slope for certain terrain, leading to overly conservative Mt values, as shown in Figure 2.
Figure 2: CHECKWIND v2.2.1 results
The local minimum criteria was intended to avoid situations where the 500 m segment might identify the “base” as being halfway up/down a slope, which seemed counter intuitive. Regardless, we’ve adjusted the algorithm and removed the local minimum criteria and now rely solely on the 500 m segment method. This has led to an overall reduction in Mt values across all of our test sites, as shown in Figure 3.
