COST of Wisconsin/Gilder Center

It’s rare that a building’s design can become so immediately iconic – an attraction unto itself. Gaudi’s Sagrada Familia in Barcelona comes to mind. It is a visual feast – a sculpture that takes the shape of a building. Many architecture critics are already claiming the same for the newly opened Gilder Center at the American Museum of Natural History (AMNH) in New York City.

HIGHLINE GARIBALDI SPRINGS ROCKSCAPE RETAINING WALL

This retaining wall was contracted for a new townhouse development project in Squamish, BC, Canada. Vancouver Shotcrete & Shoring Inc. has serviced many municipalities and private companies over the past 30 years in the fields of shotcrete shoring, pools, and custom rockscapes.

The shotcrete retaining wall was designed to be anchored by Titan 40 self-drilling anchors with a test load capacity of 52,000 lbs (24,000 kg) each, spaced every 6 ft (2 m) on center. The temporary 4 in. (100 mm) shotcrete was reinforced with 4 x 4 x 1 in. (100 x 100 x 25 mm) welded wire mesh, with a 0.8 in. (20 mm) continuous whaler lining to span the load between each anchor. The engineer specified a 5800 psi (40 MPa) shotcrete mix for this purpose.

ASA Outstanding Shotcrete Awards Program

The ASA Outstanding Shotcrete Project Awards Program exists to recognize excellence and innovation on projects in which the application of shotcrete has played a significant role.

ASA’s Annual Outstanding Shotcrete Project Awards Program provides an exciting real-world demonstration of the exceptional advantages of placing concrete via the shotcrete process. Many sustainability advantages are also inherent in the shotcrete process and play a significant role in winning projects as well as the project owner’s ultimate decision to use shotcrete as the method of concrete placement. Projects must be completed between January 1, 2021, through September 1, 2023, and can be submitted in the following areas: Architecture │ New Construction, Infrastructure, International Projects, Pool & Recreational, Rehabilitation & Repair, Underground.

To assist in your submission, we have provided submission resources to inform you of the submission guidelines, a list of questions, and a copy of the owner release form. Please email any questions to [email protected].

The Jetcreter – The First Continuous-Feed, Dry-Mix Gun

During the summer of 1970, on my 18th birthday, my father woke me up and told me they needed me on a job. I drove out that morning in July to the Crucible Specialty Steel plant in Midland, PA. It was my first experience working on a Gunite job. We were gunning refractory in a vessel, and I was throwing 100 lb (46 kg) bags of pre-packaged refractory into a paddle mixer to pre-dampen the material. We emptied the paddle mixer on sheets of plywood and shoveled the pre-dampened refractory material into the dry-mix shotcrete gun’s hopper. The Jetcreter was a continuous-feed gun, and it was tough for us to keep up with it. It was a very long day for me because it took 15 hours to complete the gunning. I left the house that morning in the dark and returned home in the dark. That was my introduction to “Gunite” (now referred to as dry-mix shotcrete).

Shotcrete has become the placement method of choice for an increasing number of architectural applications. From intricately formed building structures to landscapes and zooscapes, shotcrete meets the construction needs of architects, designers, and contractors alike. Many new structures, from foundations up to domes, and everything in between, also find the flexibility, adaptability, and durability of shotcrete to be their application of choice.  Shotcrete construction can often be completed faster and more economically than other conventional construction techniques.
