Aurland Lookout
The ramp is constructed with load-bearing galvanized steel, and then covered with environmental pressure treated pine. The load-bearing system is two parallell frames with a rectangular section. There are seven steel sections to make the on-site construction easier. The cross-section has been chosen to take in consideration and are 300m wide and 1100 high, while the the ”legs” of the ramp are a smaller at 300mm x 800mm. The most tension is in the curve of the ramp. A framework in the floor of the ramp criss-crosses from this point all the way to the foundation in the road. The floor of the ramp has an inner construcion og steel trusses with a center distance of 1m.
The floor of the ramp is 65mm massive wood, placed with a small fall to each side of the ramp. The floor is screwed from the underside to the steel frame. The ”rails” on the edge of the ramp are covered with 65mm of laminated wood. The wooden joins on the side of the rails are semi-cirle joints that make the joins less visible from a distance. The underside of the ramp is coved in open wooden slats.
The ramps has two concrete foundations. The upper foundation deals with most of the side forces from the wind. This foundation is made as a lying ”U”, and nine long tension bolts are fastended to the mountain in go under the road and are fastened with bolts. The second, and lower foundation, is the foundation for the ”legs” of the ramp. This foundation is bolted in two places to the mountain-side.
The WC building is constructed of place-formed concrete that form the floor, side-walls, and roof. The concrete is then covered with ”elite-crete” to give a black coating of rubber-like surface. The end-walls are 65mm solild wood. The end wall towards the fjords are mostly glass.
