The trampoline park installation period depends on the facility size and the installation team. 

For example, if it's a 1000sqm2 trampoline park, we would send two engineers to guide the installation and it takes about 3-4 weeks to finish. By the way, we would need assistant workers to help our engineers.  

If you install the park on your own, probably it would take longer time.   We could offer a comprehensive set of plans or manuals for you to do the installation.
