Contracting and Subcontracting

Because of Dave's care for trees and his skill and strength in working with them, commerical organizations often find it worthwhile, both in terms of productivity and risk mitigation, to hire Dave to look after the ongoing maintenance of the trees on their property. Companies such as real-estate firms or golf courses with large or numerous properties to maintain will find such an arrangement cost-effective.

Dave is also available for subcontracting to utility, tree-care, landscaping, or lawn-care companies. Subcontracted work usually involves trees for a client who is very particular, who has an emotional attachment to their tree(s), or who has a tree in a precarious state or awkward situation.

Utility companies with large spans of trees to prune or remove will also be interested in securing Dave's services because he possesses a utility arborist license and many hours working amongst Hydro lines while supervising the work of apprentice-arborists. In either case, if required, a ground crew intent on a careful clean-up of a job site can also be hired to accompany Dave.

Here's an example of Dave performing a subcontracted removal: Many people make the mistake of planting a poplar tree in an urban area. This is unwise because poplars quickly become too big for the space available and have to be removed. These large-scale removals, often near a garage, fence, house, or other high-value asset, are Dave's specialty. In this particular removal, Dave stops briefly to say hello.

Click on the link below for another example of a job which required Dave to travel to Calgary to assist a local tree-care company with the removal of a 115-foot tall poplar in an upscale Calgary neighborhood. In this job, Dave worked with Chris Paterson, one of the best climbing arborists in the industry today.

Using a Crane

Some jobs are best accomplished through using a crane to remove a tree in one large piece and then place it directly on a flat-bed trailer for hauling to a mill or other destination. Dave has assisted in several jobs of this nature. He is known for his mathematical/physics skills used to assess proper placement of the crane assembly. Jobs of this nature are very dangerous -- both to person and property -- if approached incorrectly.

Power-line Work (Hydro)

Dave is one of a select group of arborists who is authorized to work near hydro lines. In this regard, he has earned the IVMAA (Industrial Vegetation Management Association of Alberta) utility arborist designation. Working near power lines that transmit from 2,400 to 25,000 volts obviously requires intense concentration, confidence, and skill.

Training: Production Arborist Skills

During his years in the arboriculture industry, Dave has trained many practitioners, primarily through exposing an apprentice to successively more responsibiltity during on-the-job training. A formal training program is now available for those who wish to learn Dave's unique and esteemed approach to his trade. This program augments Dave's accredited chainsaw safety education and delivers the most practical production-arborist training available in North America today. Rather than a purely-theoretical program, it provides arborists with the opportunity to hone the skills they require to safely begin working on a job site.
