For the past 11 months the Ottawa Bluesfest organization has been working toward increased safety measures for the main stage that will be in place for the 2012 event.
Festival organizers have chosen a new design and product for the main stage roof structure. In 2011, the Ottawa Bluesfest utilised a Mega Stage MK III mobile stage structure. This differs from the Premier Global Productions (PGP) roof structure that will be used this year, in that the MK III is a mobile structure that is of steel and aluminum construction, while the new PGP stage is prefabricated in the plant, is of welded steel construction, and is assembled “from the ground up” on site.The Premier Global Production roof system, to be used at the 2012 Bluesfest, is composed of open web steel trusses spanning 76\’ across the main stage and 60\’ upstage to downstage with 26\’ by 12\’ PA grid on each side of the main stage. The main trusses are 24\” wide by 60\” deep. The trusses are connected at their ends by grade-8 structural bolted connections top and bottom and additional steel bracing. The columns are lattice towers are 24\”x24\” for the main stage and 18\”x18\” in the PA bays. All components are of welded steel construction (built in the plant) and all on-site connections are Grade-8 structural bolted connections. This system has concrete ballast on all tower bases, with a total ballast weight of 113,000 kg (250,000 pounds).
The 2012 PGP stage is being analyzed for standard loads (lighting and sound) configurations and also specialised rigging loads for some performers. All load scenarios are analyzed using an engineering finite element model of the stage. The final design will be signed and certified by a professional engineer. We have an emergency plan in place to address inclement weather
It is important to note that the new main stage is a completely different design style from the scaffold stage at Parc Downsview Park, where an accident occurred on Saturday June 16, 2012. While we do not have the design details of the stage at Parc Downsview Park, from the photographs it can be seen that it is of scaffold construction versus our stage from Premier Global Productions, which is of all welded steel construction and structural fasteners.
