2024 Award Nominations

ASA’s Outstanding Shotcrete Project Award Nomination

The ASA Outstanding Shotcrete Project Awards Program recognizes excellence and innovation on projects where shotcrete placement played a significant role.

Submission deadline: October 1, 2024

Shotcrete project completion requirement dates: January 1, 2022 – September 1, 2024

ASA’s Annual Outstanding Shotcrete Project Awards Program recognizes the projects that exemplify the advantages of placing concrete with the shotcrete process. These projects confirm the distinct benefits of shotcrete placement in concrete construction, including enhanced sustainability, architectural creativity, increased efficiency, and high quality. All with concrete’s inherent durability and serviceability.

Winners will receive their award and present their projects during ASA’s Annual Awards celebration, held next year at ASA’s 2025 Shotcrete Convention & Technology Conference, March 9-11, 2025 in Savannah, GA. Winning projects for each category are also published in Shotcrete magazine’s annual Awards Issue, featured on the Shotcrete.org, Awards portal and through press releases and social media channels.

Submittal Process:

You may submit as many projects as you would like, each one carries a $50 entry fee.

To qualify, projects must be submitted by 5:00 PM ET on October 1, 2024. Project submittals will not be returned and may be used by the ASA for display at meetings and trade shows. Application must be submitted through this website. No hand-written pdfs will be accepted. Winning projects must also submit an Owner’s Release form in order for the award to be conferred.

Direct Questions to: [email protected] | 248/983.1712.

To better assist you, we have compiled a list of questions to assist in collecting the necessary material for submission, the 2024 Entry Guidelines, and a sample of the Owner's Release form.

We are a shotcrete company in Southern California, and I have a technical question about an issue that has recently come up. Is there any official ASA or ACI guide/spec that recommends or lays out the use of a certified nozzleman on a job that he was not “job site” approved for? For instance, a nozzleman who did not shoot a test panel was overseen by the approved nozzleman for that job site. I understand that the approved nozzleman can oversee another ACI-certified nozzleman on the job so that he can rest and oversee production. Seeing as the approved man is overseeing the nozzleman, is it the same as him shooting the wall himself?

It appears you are talking about a nozzleman who has not been pre-qualified by shooting a mockup panel on a specific project. There is no official ASA or ACI document that addresses this issue. However, this situation is similar to what ACI guidance provides regarding ACI-certified Shotcrete Nozzlemen and Nozzlemen-in-training. ACI’s Certification Program Policy for Shotcrete Nozzleman and Nozzleman-In-Training Section 1.04 states: “ACI Shotcrete Nozzleman-In-Training (NIT) certification is available to applicants who do not possess 500 hours of work experience but do possess a minimum of 25 hours of hand nozzling work experience in the process being sought (vertical orientation only). The examiner of record may require an ACI-certified nozzleman to be present during the performance exam; however, the ACI-certified nozzleman’s interaction with the examinee is strictly limited to the safety of the shooting operation.”

We are having a pool installed and would like to know if shotcrete should be placed when severe weather is forecasted for late in the day or the next day? Is it possible to cover the area after application to protect it?

Shotcrete is a method for placing concrete. Concrete has a set time that provides hardness of the in-place concrete. Final set may take anywhere from an hour to several hours depending on the concrete mixture and the weather.

Hot weather has a faster set time than cold weather with the same concrete mixture. If the pool is shot in the morning, it may be hard enough to tolerate a rainstorm in the late afternoon. The concrete should certainly be set by the next day unless there is a very cold overnight temperature or a problem with retarder in the concrete mixture. Tarps could be placed over the vertical walls to protect them from a sudden rainstorm. The floor may be harder to protect as the rainwater wouldn’t necessarily drain off the floor.

If concrete is exposed to rain and the surface isn’t washed off in any way, the concrete should be good. Similarly, if you are expecting freezing temperatures overnight, the fresh concrete must be protected from freezing. This may require using vented heaters and insulated blankets. The goal of the cold weather protection is to keep the surface temperature of the fresh concrete above 50°F (10°C). More details on cold weather protection can be found in ACI PRC-306-16 Guide to Cold Weather Concreting available directly from ACI’s bookstore (concrete.org/store.aspx).

Please direct me to the proper guidelines for the hydration of shotcrete.

By hydration, I’m assuming you are referring to curing of freshly placed concrete. A minimum of 7 days of continuous wet curing is recommended. Continuous means the exposed concrete surface is wet the entire duration. Not just “watered” twice a day as has sometimes been suggested by contractors. Use of a spray-on curing membrane is an option if for some reason water curing is not practical.

If you are looking specifically at swimming pools, this ASA Pool and Recreational Shotcrete Committee Position Statement “Curing of Shotcrete for Swimming Pools” provides more details: shotcrete.org/wp-content/uploads/2022/01/218216_ SCMSummer21_PS7v2.pdf Also, for a more detailed look at curing, the American Concrete Institute (ACI) document, ACI PRC-308-16 Guide to External Curing of Concrete is an excellent reference.

You can find this at ACI’s bookstore (concrete.org/store.aspx). Finally, a good reference on the basics of concrete, from materials to placement and curing, is the Portland Cement Association’s “Design and Control of Concrete Mixtures, 17th Edition.” You can find this on the PCA website bookstore.
