Stream Crossings - Eric L Kay
Logging and Sawmilling Journal - July/Aug 1995
A comprehensive look at the factors that concern us when we approach a Forest Road "Stream Crossing"
Printed as a center pull-out "Wall Chart" and included with the Jan 1996 issue of Logging and Sawmilling Journal magazine

Evaluate Historical Behavior of a Stream - Robert P Willington
Excerpt from an article entitled "Stream control for forest Roads" which appeared in "Drainage Structures for Logging Roads" April, 1979, Sponsored by; the Association of British Columbia Professional Foresters and the Center for Continuing Education, and the University of British Columbia.

Excavator - Costing, Budgeting and Equipment selection - Eric L Kay
Written for a client considering the purchase of an excavator with the intended purpose of doing Deactivation work, but yet wanted a machine that remained versatile by being able to do other work in both the Forestry and Civil sector.

Comercial Thinning, Thinning by the Yard - Jean Sorenson
Canadian Forest Industries - July/Aug 1995
Aiming at zero impact. A unique, small-scale thinning operation on Vancouver Island is achieving record low site-impact levels.

In Review - (book review)
Westcoast Logger - Nov/Dec 1994.
Supervisors and Operators Manuals - Eric L Kay
"A must for anyone working in the forest industry - (quote)"

 

Code Requires a Soft Roadbuilding Touch - Eric L Kay
Truck Logger - Feb/Mar 1995.
Forest roadbuilding, with its long-term environmental impact, has not escaped the government's regulatory overhaul.

Machines shed weight to look good for the code - Peter L Dixon
Truck Logger - Apr/May 1995.
With the implementation of the FPC, the future has arrived. It will require learning, change, and innovation. The BC Logging industry is responding to the challenge, as is "svelte" new equipment.

Industry stretching out to reach timber - Jean Sorenson
Canadian Forest Industries - April/May 1995
In depth interview with Eric L Kay reguarding the Code Implications and impact on the Forest Industry and how Industry is meeting the new demands.

Roadbuilding to the code - Jean Sorenson
Interlog - Fall 1995
Water management in Roadbuilding, interview with Eric L Kay

ROADBUILDING – Hydraulic Rock Breaker - Eric L Kay
Truck Logger Magazine - January issue, 1999
“Hydraulic Hammer Handles Buttle Bluffs Job”
Case study – Cost-effective low-impact coastal Forest Road construction
Construction of the Buttle Bluffs main in the fall/winter of 1999, located in the Mount Adrian area of central Vancouver Island required a narrow footprint with a minimum of environmental and visual impact.  Road running width was kept at a minimum (yet ensuring user safety).  To reduce the amount of disturbed ground absolute control of the cut and fill slope angles were desired and these were kept to a minimum as was the variable width right of way clearing.
TimberWest chose the use of the hydraulic hammer instead of conventional drilling and blasting for the Hammers ability to break rock without environmental impact.
 

Stabilizing Slides Using a Spider Excavator for Headscarp Removal and Installation of Remedial Drainage

Presented at the 1998 Annual Forest Site Rehabilitation Workshop, Kelowna BC - Eric L Kay, Rob Wilson.

INDEX           Part 1              -           Spider Excavator

Part 2              -           Headscarp removal

Part 3              -           Multi-flow pipe

Part 4              -           Contour Drains

Spider Excavator -  The conventional track excavator is a common workhorse in the logging industry of BC.  On steeper ground the operator needs to bench into the slope to gain access and help insure user safety.  However, this is not always desirable when we are concerned with stability of a slope since it may lead to costly problems related to placement of the excavated material and other problems such as a loss of toe support and over steepened cut and fill faces.

As an alternative, the Spider Excavator is a machine that has the ability to walk, (like a spider), with its 4 legs on steep slopes of up to 100% without the requirement to construct large benches or create undue ground disturbance.  The only effect is the ground compaction at each of the pads on the base of the spiders "legs".
