What You'll Learn
The transformation time can vary
The size of the crew can significantly impact the transformation time. With a larger crew, the process can be completed more efficiently and rapidly. For example, the Staples Center in Los Angeles, which hosts both basketball and hockey games, has been known to convert its arena in as little as 90 minutes with a dedicated crew. On the other hand, smaller venues or those with fewer resources may take longer to make the transition.
The efficiency of the crew also plays a crucial role in reducing the transformation time. A well-trained and experienced crew, familiar with the process and equipped with the necessary tools, can expedite the setup process. In contrast, a crew that is less experienced or lacks the proper equipment may require more time to complete the task.
It is worth noting that advancements in technology have played a significant role in reducing the time required for this transformation. Modern arenas are now designed with innovative systems that facilitate quicker conversions. For instance, the University of Phoenix Stadium features a massive moving platform that allows an entire football field to slide in and out of the stadium, eliminating the need for time-consuming conversions.
The transformation time can also be influenced by the specific requirements of the basketball and hockey teams. Each team may have unique specifications for their playing surface, including branding, markings, and other customizations. Accommodating these requests can extend the setup time, especially if specialized equipment or materials are needed.
In conclusion, the transformation time from a hockey rink to a basketball court can vary significantly, ranging from as little as 90 minutes to a full day or more. This variation is due to several factors, including the system used, crew size and efficiency, advancements in technology, and the specific requirements of the teams involved. Efficient utilization of resources and continuous innovation in arena design will likely further reduce transformation times in the future.

It can take anywhere from 90 minutes to a full day
The time it takes to convert an arena from a hockey rink to a basketball court varies depending on the system used, crew size, and efficiency. The transformation time can range from 90 minutes to a full day.
In 2012, the Staples Center in Los Angeles hosted six playoff games in four days, requiring the arena to change from a hockey rink to a basketball court and back over the course of less than a week. The crews at the Staples Center were able to achieve this rapid transition with the help of modern technology.
The process of converting the arena typically involves removing the walls and glass panels surrounding the hockey rink. Then, special insulated plywood is laid out over the ice surface, followed by the installation of the hardwood basketball floor on top of the plywood. The plywood serves the dual purpose of keeping the basketball court warm while maintaining the ice surface below at a cool temperature.
The transformation time can be influenced by the number of workers involved, with a larger crew potentially enabling a faster conversion. Additionally, the efficiency and experience of the crew members can impact the overall duration of the process.
While it is impressive that the conversion can be completed within 90 minutes, it is worth noting that this rapid turnaround time may not be achievable in all arenas or with every crew. The upper end of the timeframe, a full day, allows for a more relaxed pace and accounts for any potential delays or challenges that may arise during the transformation process.

The ice stays frozen underneath
To convert an ice hockey rink to a basketball court, the ice underneath must be kept frozen. This is achieved through a complex refrigeration system. The ice is maintained at a temperature of around -4°C, which is ideal for ice hockey. To achieve this temperature, a liquid refrigerant, typically ammonia, absorbs heat from a secondary liquid, often brine, which has absorbed heat from the ice. This causes the ammonia to boil and vaporize, and the vaporized ammonia is then pressurized by a compressor, significantly raising its temperature. It is then condensed back into a liquid and circulated back into the pipes to restart the cycle.
This process of refrigeration is similar to that used in refrigerators and air conditioners but on a much larger scale. The pipes circulate the entire floor, drawing heat from the ice surface. The brine is colder than the ice surface, so it removes the heat. The brine then returns to the chiller several degrees warmer and releases the heat it has absorbed.
To convert the rink to a basketball court, insulated plywood is laid out over the ice surface, and the basketball floor is pieced together on top. This process can take anywhere from 90 minutes to a full day, depending on the system used and the number of workers.
The ice rink itself is created by spraying water onto a chilled concrete slab and freezing it in thin, individual layers. This process takes about three days. The concrete slab is embedded with pipes that circulate coolant, such as glycol, to keep the ice frozen. The pipes delivering the coolant are similar to an air mattress filled with coolant, with the ice sitting on top. The concrete slab is also heated to prevent the ground below the ice from freezing, which could cause it to expand and crack the rink's structure.

Basketball courts are smaller than hockey rinks
The process of converting an arena from a hockey rink to a basketball court typically involves removing the walls and glass panels surrounding the hockey rink, and then covering the ice with insulated plywood and the basketball floor on top. This process can be completed in as little as a couple of hours, with some sources stating that it can take anywhere from 90 minutes to an entire day, depending on the system used and the number of workers involved.
The insulated plywood used in the conversion process serves the important function of keeping the basketball court warm while simultaneously maintaining the cool temperature of the ice below. Each piece of plywood weighs between 175 and 190 pounds, and when pieced together, they form a heavy surface that stays in place during basketball games.
The transformation of an arena from a hockey rink to a basketball court is a testament to the wonders of modern technology. This process allows for the efficient utilization of arenas, accommodating multiple sports and events, including basketball games, hockey matches, and concerts.
While the conversion process is impressive, it does come with certain challenges. One issue is managing the temperature to prevent condensation on the basketball court. To address this, arenas utilize coolant pipes under the ice to maintain the necessary temperature for both the court and the ice. Additionally, the use of separate pieces of plywood for the basketball floor can result in a slightly uneven surface, though this is not always noticeable during gameplay.

Crews can transition quickly
Crews can transition basketball courts and ice hockey rinks quickly, with transformation times ranging from 90 minutes to a full day. This is made possible by modern technology and efficient crew work.
The process typically involves removing the walls and glass panels of the hockey rink, then laying out special insulated plywood over the ice surface. The hardwood basketball floor is then pieced together on top of the plywood, creating a warm court that sits securely on top of the frozen ice below. The basketball court is much smaller than the hockey playing surface, so the transformation is relatively straightforward.
The efficiency of the crew is key to a quick transition. With a large and well-trained crew, the process can be completed in a matter of hours. In some cases, arenas have managed to convert from hockey to basketball in under three hours.
The availability of modern technology also plays a significant role in reducing transition times. For example, the ice-bearing concrete slab embedded with temperature control mechanisms allows the ice to remain frozen during basketball games, eliminating the need for time-consuming melting and refreezing processes.
Additionally, the use of heavy plywood and well-engineered flooring systems ensures that the basketball court stays in place securely, preventing sliding or shifting during gameplay. This technology enables arenas to host multiple sports events without requiring separate facilities for each discipline.
