What are some interesting projects you’ve worked on in the past?
Since 1986, Mariani Metal has transformed concepts into architectural and structural marvels. We’ve delivered products in some diverse categories including architectural metals, architecturally exposed steel, miscellaneous metals, custom metal and glass enclosures, and automotive machinery. Past projects my team and I have worked on include the Art Gallery of Ontario feature stair, the New York Times Building lobby, the Viva transit hub station on Highway 7 at Jane Street in Vaughan, Weatherhead School of Management in Cleveland Ohio, the United States Air Force Memorial, and Goldman Sachs feature stair, among others.
What is the most exciting aspect of the Garrison Crossing project?
The most exciting aspect is the ability to work with the design and construction team to fabricate and deliver a stainless steel bridge. Few bridges are conceived utilizing stainless steel, and fewer companies can fabricate and work with this grade of stainless steel (duplex 2205).
What was the most challenging part of the fabrication for the Garrison Crossing bridge?
All bridge projects are complex by nature. Working with this grade of stainless steel material adds a level of complexity to the welding and fabrication process, because the base material is not as easy to weld as steel. Additionally, there are many parts and components of the bridge that must be cut and fit in a precise manner before welding. With care and cooperation, we have undertaken a rigorous quality control and assurance program with the construction and design team to ensure that all relevant standards and specifications are being met.
Are there any unique fabrication techniques you used for the Garrison Crossing bridge?
We are using the flux core welding process to weld the stainless steel together. We have created precision jigs to check and ensure the pre-camber of the bridge before delivery to the site, and we constantly monitor the geometry via the use of total stations to check coordinates.
