The Abbot Pass Hut foundation had become unstable and the structure was in jeopardy of collapsing. Parks Canada required a team to tactically remediate and dismantle the hut before it slid down the mountain.
Methods and Solution
Tangiers was contracted to stabilize, remediate and dismantle the 100 year old stone structure. Located in a highly protected park area at nearly 10,000 feet this provided numerous challenges. The site could only be accessed by helicopter. A high degree of environmental stewardship was needed. A small group air mobilized all equipment to the areas, the interior was abated and dismantled – numerous artifacts were recovered, the roof was removed and then the walls. Finally, the area was remediated leaving only a partial wall and the original plaque.
The project was completed in time despite winter storms that hampered efforts. Over 3 cubic meters of building stone was recovered and flown down to valley bottom for Parks Canada to catalogue. All components of the building were recovered and flown off site.
