Calliope Central Bowls Club

BRIEF Calliope Central Bowls Club came to Greenline with the vision of covering their green to provide year-round, day and night lawn bowls with a cyclone-proof membrane structure. The site was challenging with limited access around the green for large construction equipment, and a client preference for no access onto the green at any point during construction. Cyclonic wind conditions meant that the structure needed to be certified for extremely strong wind events.

OUTCOME Calliope Central Bowls Club will be the only one in the Gladstone region that will have a permanent roof. It allows competitions to be scheduled well in advance without the worry of weather. The club is building a strong focus on getting the local community involved with barefoot bowls and social events, so it is more than simply a bowling club – it is a local destination.
The curved roof structure was designed to withstand the massive loads from cyclones and was constructed from curved circular steel members and high-tech premium waterproof PVC membrane. The membrane offers 100% UVR block for a safe playing environment for all ages while allowing 9% natural light transmission to reduce the need for artificial lighting during the day. The structure has efficient LED lighting for evening events, and a PA system to extend the buildings public address into the area. The project was conducted with a unique methodology with zero access to the green at any point during construction.
