Project consisted of a repair to a highway overpass bridge deck overhang that had been struck and damaged by a highway truck. Project deliverable was to remove all damaged concrete on the existing overhang, as well as form and pour a new overhang. The work took place over an active, busy, 6 lane road where work could only be performed on nightshift with traffic closures.
As work windows were limited Quattro devised the most efficient methods for construction – namely the installation of a falsedeck. This falsedeck served as a platform to ensure safe demolition (overhang concrete was cut into slabs and rigged and picked off with an excavator, while non-overhang concrete was chipped with a remote-controlled demolition robot), as well as a platform for forming and pouring the new overhang soffit.
For further efficiency, Quattro performed a pre-works inspection of the bridge and was able to use the existing tie-holes in the precast box girders for installing the overhang brackets for the falsedeck (with the consent of the EoR). This ensured that no new holes were drilled in the concrete box girders.
