Facade and Window Refurbishment – City Apartments with Commercial Shops

2010 – Present

IMG_3448, Modifed We are the Superintending Engineer in Brisbane for this facade refurbishment project (four separate residential towers, each consist of seven levels constructed above commercial/retail tenancies on the ground floor podium level, serviced by multi level carparks). The project involves major façade repairs and refurbishment and replacement of windows. We were initially engaged to provide technical support during emergency repairs and carry out a full defects inspection which revealed the following issues:

  • a conspicuous lack of consistent external façade control jointing,
  • moisture ingress at the heads and sills of windows
  • poor waterproofing of the window and door frames and their sills
  • cracking to façade coatings to walls (potential points of water entry).
  • Discontinuous expansion jointing
  • Missing and inconsistent control jointing
  • Spalling and cracking render
  • Calcite staining from leaks under patio walls ; planter boxes and edges of balconies, and calcite staining from cracks around windows and patio spitters
  • Cracking and deterioration of major expansion joints
  • Lack of continuity of expansion joints from roof to building facades
  • Bridging of major expansion joint to Tower 1 by parapet wall
  • Under Design of expansion joint – investigation into the adequacy of the expansion joint, i.e. under-sized
  • Cracks in parapet walls allowing water ingress behind façade coating at top of building
  • Roof spitters unsealed underneath, allowing water ingress behind façade coating at top of building
  • Poor detailing of roof/parapet waterproofing upstand leading to cracking
  • Concrete hoods to robe drops of buildings – waterproof coatings incomplete to tops and sides
  • Corrosion to steel columns and frames of sunhoods Lack of valleys to sun hood

We prepared a repair specification and took the project to tender. The repair and window replacement works started in January 2013 and we expect the project to be complete in October 2014.
