Over the last decade or so, forest companies have been targeting stands that are now coming into maturity on the coast. Forest engineers and terrain specialists are tasked with layout and assessments throughout terrain that has previously been roaded and logged. Sounds simple enough, right? Maybe not. As often as not, old roads above the proposed operations are totally ignored as they are not part of the plan. Yes, many of the pre-code roads (before 1995) have been effectively deactivated, but there are just as many roads out there that are in a state of impending failure, including cutbank and fillslope failures, tension cracks, diverted drainage, and plugged culverts. As part of a professional's due diligence, it falls upon them to ensure that these roads are properly assessed and remedial measures taken to fix problem areas or find ways to mitigate the risk to workers below. It is not just old roads in the assessment area of proposed operations that need thorough investigation, but those above the site. This webinar will proceed with examples of what may happen when we do not consider upslope hazards.
Del Ferguson became a registered, practising geologist in 1980 working largely in mineral exploration across Canada. In 1990 he became involved in BC’s Forest Industry as a road construction supervisor and, in 1994, a terrain specialist. Del holds a diploma in Forestry Advanced Engineering from the University of British Columbia and is a graduate of the University of Western Ontario, holding an Honours B.Sc. degree in geology.
As president of Aztec Geoscience Inc., he has mentored and provided work to geoscientists involved in terrain stability analysis for the natural resource industry, primarily in forestry, but also Run-of-River hydro projects, BC Hydro transmission lines, road reactivation and deactivation projects, and mineral exploration projects. Most of Aztec’s work has been on Vancouver Island and the adjacent Mainland Coast. Del lives in Comox and is a member of the Engineers and Geoscientists in the Resource Sector Division.
