The structure consists of an outer ring made of nine glulam columns, which were set up rotationally symmetrically with an angle difference of 40° each, thus forming a polygonal spatial structure.
A steel pylon made of a round pipe was built inside the tower. Steel spiral stairs with steel grids and a tunnel slide are attached to the pylon, which is connected to the tower at two height levels: The pylon is connected to the tower in two places, at a height of 78.74 ft and a height of 131.81 ft.
Visitors have access to the tower either by coming along the treetop walk ending at 78.74 ft above ground, or by climbing the spiral staircase. From there, they can reach the viewing platform by climbing a spiral timber construction that is attached to the timber columns by means of cantilevered steel beams.
The construction has been stiffened by a close mesh of diagonal steel members anchored in the timber columns. In the lower part, four horizontally extending ring structures made of steel pipes were additionally arranged

Product Feature
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
