2013 – Wallace was asked by Arrow International to undertake the seismic upgrade of Cumberland House at 235 Willis St due to our previous experience with strengthening works and resources available in a very tight timeframe. The student accommodation building seismic strengthening involves two sprayed concrete Shearwalls 5 floors high the full width of the building, self-compacting concrete spandrels and upgrades to the existing columns and floors. The seismic upgrade of the building was not originally planned when the building’s interior was due to be refurbished over the Students summer break due to the impending sale to overseas owners and Wallace had to commit to having the strengthening work completed by the first week of February. Work started in December 2012 one week behind schedule and Wallace worked all through Christmas with a large crew of staff and subcontractors and finished the strengthening works Three weeks ahead of schedule on the 16th of January 2013. Arrow has expressed their gratitude at the hard work and professionalism that Wallace showed to allow them to complete the buildings refurbishment on time.
