For the exterior restoration of the Rundel Memorial Library, our team provided the temporary works engineering needed to safely access and complete repairs while minimizing disruption to the surrounding area and protecting the existing structure.
The project presented several unique challenges, including limited site access, work on/over existing plaza structures, and work over an active river. We performed structural analyses of the existing plazas and roof to determine their capacity to support construction loading. Where required we designed temporary shoring and platforms to support the existing structure or re-distribute loads to existing elements that could support the temporary loads.
Our temporary access scope included the layout, tieback, and support design for swing stages on each building elevation, three separate systems scaffold configurations, layout and design of base support and anchorage of ReechCraft Powermast work platform systems, and a custom elevated work platform over the river supported from the existing structure.
The elevated platform was designed so it could be progressively erected after the first three brackets were installed from a man basket. This eliminated the need for four separate crane mobilizations that would have required temporary bridge lane closures, reducing project cost, shortening the construction schedule, and minimizing impacts to the public.
