The Plant and Resources Committee and the Finance Council have been working on repairing the Church Roof Skylights for some time. The Roof Skylights have leaked since the Church was first built. In the intervening period, the roof skylights have been repaired a number of times but each time retaining the original design. The last time the skylights were repaired, was in 2014.
In recent rains, water penetrating the skylights, has damaged the Church ceiling and a claim has been lodged with CCI but the source of the leaks must be repaired before the consequential damage to the ceiling can be repaired.
Bligh Tanner (BT), Engineers inspected the skylights and determined that the paths of water penetration included through the apex flashing, through the glazing sealant and through the vents under the skylights. The 18 panes of glass in each of the 16 skylight triangles sit in a steel inverted “T” Bar frame. BT has advised that no sealant manufacturer will warrant their product to seal glass and steel.
Each of these paths of water penetration results largely from an original design flaw.
BT has provided a preliminary design to:-
1. rectify 2 of these design flaws by:-
a. installing a single pane of glass in an aluminum adaptor; and
b. a new apex flashing.
in each skylight triangle; and
2. minimize the risk of water penetration through the vents under the skylights by installing baffles.
The Church is a local heritage place listed in the Brisbane Town Plan. Any work on the Church (including the skylights) needs impact assessable development approval unless the work is carried out in accordance with a heritage exemption certificate (HEC) issued by the Brisbane City Council. On 31 May 2023, OLMC obtained a HEC for works based upon the BT preliminary design.
BT will now proceed to provide detailed design so tenders can be called for the works to be carried out. The skylights are 13 m above the floor of the Church. Carrying out the works at that height will involve some almost unique difficulties. The current period is a time of escalating costs. Until tenders are received, OLMC cannot determine the cost or how the cost will be funded."
