![]() The mock-up consisted of three cantilever beams and the roof panes mounted on these plus the bent façade panes, and this was presented to the architect and the client as the result of the planning work. Seele initially built a mock-up of the proposed solution on its own testing grounds in Gersthofen. From inside the building, the uninterrupted glass façade permits spectacular views of the area in front of the Jefferson National Expansion Memorial and also the city skyline. The joint between façade and glass roof permits movement. The largest of the 24 panes making up the façade measures 1.4 x 5.5m and each pane weighs 460kg. A pattern printed on the glass lends the roof glazing a feeling of vitality, but also regulates the transmittance of light and heat. The 38 stainless steel cantilever beams are made from milled solid stainless steel sections tensioned with tie bars and fabricated in seele’s own plant in Plzeň. It is the centerpiece of the Gateway Arch. The Arch is made of stainless steel and is a parabola in shape. The Arch stands 630 feet tall and is the tallest man-made monument in the Western Hemisphere. Louis Arch is an iconic structure in the city of St. Louis as a fur trading post to construction of the Gateway Arch and beyond.The roof comprises a total of 74 three-ply laminated panes in sizes of up to 5.5 x 2m which are supported on a steel structure weighing 85t in total. Designed by Eero Saarinen and completed in 1965, the St. Inside, the Museum at the Gateway Arch provides an opportunity to engage with 200+ years of history, from the founding of St. They can walk their dogs or eat a picnic lunch in the shadow of the monument. People can view the Arch from many different angles as they enjoy five miles of walking and biking trails. Louis, providing green space for park neighbors and visitors from all over the world. In addition, Gateway Arch National Park encompasses 91 acres in downtown St. The tram ride to the top of the Arch allows millions of visitors to enjoy the spectacular views from the top and marvel at the architectural and engineering feats that make it possible. The Arch’s one-of-a-kind transportation system is an innovative solution to a very unique problem. ![]() Only a combination of these principles would solve the problem. The triangular shape and the different slopes of the Arch would not allow for a standard elevator to reach heights above 300 feet the slope of an escalator would not follow the required curvature the distance up one leg and down the other was too long for any chains or cables to traverse and the Ferris wheel principle would not allow visitors to exit at the observation deck. Together, the Engineer and the Architect would find a solution.īowser considered the constraints. Eero Saarinen needed someone to design a “transporter” that could move thousands of people to the Top of the Arch every day without distorting the exterior of the Arch. These elevators could travel horizontally, diagonally, and vertically through a structure. What is engineering if not problem solving?ĭick Bowser, a second-generation “elevator man,” had worked with his father to develop, manufacture, and install Bowser Parking System elevator equipment. He wanted people to visit an observation deck at the Top, but he had a problem – how to transport people to the top from inside such an unusual structure? No ordinary elevator would do, and few would want to climb 1,076 steps to reach the top! The complex engineering design and construction is completely hidden from view all that can be seen from the outside is its sparkling, stainless steel outer skin.įrom the start, Saarinen did not intend for people to just marvel at the Arch from afar. Each leg of the Arch consists of double-walled steel equilateral triangles which are stacked one on top of the other and welded together. In designing the Arch, architect Eero Saarinen worked with engineers to bring the project from concept to reality. The stainless-steel-faced Arch spans 630 feet at the ground level and takes the shape of an inverted catenary curve. Unique in its design and majestic in its setting, the Gateway Arch towers 630 feet above the banks of the Mississippi River. ![]() Photo/Sue Ford Spectacular views and five miles of trails deliver on an excellent experience for all Extreme wide angle view of the Gateway Arch, north leg in the foreground. We dug deep into our KSDK archives to find the original film, the only in existence, of the final piece being secured to complete the St.
