MJ Engineering Projects were involved at 175 Pitt St, Sydney providing remedial building maintenance services. The structure consisted of pre-cast concrete panels and beam framed structure with brickwork infill and 22 floors used mainly for commerical purposes. The building suffered from concrete spalling due to low concrete cover to the bars and sealant deterioration in all movement joints around the building facade.
Scope of Works:
MJ Engineering Projects was able to identify that the concrete panels were carbonated to reinforcement level, within the concrete matrix. This lead to wide spread concrete spalling at various locations around the building facades.
