I wrote to PA to ask and rec'd the following reply:
======================================
Thank you for your feedback dated 30 January 2013.
Punggol 21 Community Club (CC) Management Committee has been trying to source for a gym provider. Unfortunately it has not been able to find any suitable operator. It will, however, continue to explore other avenues of providing this service to residents.
Should you have any query, please do not hesitate to contact me at tel: 63120508.
so let's wait and see ok
