Advance Design success story: Sentier des Cimes – LH2

Project 

The Entry Tower on Sentier des Cimes project consists of a 1.5 km pedestrian footbridge. The footbridge is suspended at treetops from which comes the name “Tree Top Walk”. It also includes two towers, a main observation tower standing at approximately 40 meters (120 feet) and a 5-story elevator, 25 meters high (82 feet).
The Tree Top Walk project is a walkway primarily composed of wooden “BC fir” decking supported by glulam beams. On average the walkway is 10 meters high, and reaches over 17 meters at its highest point giving a treetop point of view to the hikers.

The elevator tower is a concrete core that houses an elevator and its proper operating equipment. On the exterior of the core there are winding stairs built of “BC Fir” glulam. The primary glulam frame is secured to the concrete core by a horizontal bracing system composed of glulam members and steel connections. The Frame and core of both towers are supported using raft concrete foundations of 1,2 meters thickness.

Meanwhile the walkway sits on “BC Fir” lumber posts of approximately 500mm in diameter, assembled to mat foundations and secured to rock anchors to prevent uplift.
