The project time to build a trampoline park depends on the size of your park. Generall it takes around 3-4 months to get the facility ready for your trampoline park business. 

There are four main parts in the trampoline park timetable:

1) Design proposal: it takes about 1-2 weeks to discuss and confirm on the design proposal. Our design team would offer cad layout plan first, and then get it rendered into 3D design once layout comfirmed. 

2) Production time: production depends on the size of trampoline park equipment and our production capacity, generally it takes about 4 weeks to finish. 

3) Delivery and shipping: typically it's delivered by sea shipping from China to your country. The shipping period would be around 3-5 weeks. 

4) Installation: it depends on the facility size and the installation team we send. Generally it takes about 3-4 weeks to finish.
