Another dispatch from the ongoing Phase I renovation of Knox College at 1 Spadina Crescent for the University of Toronto Daniels Faculty of Architecture, Landscape and Design.   Structural masonry retrofit work is costly, and NADAAA has endeavoured to avoid it wherever possible in the project.  Nevertheless, there were several locations where the requirements of the program, security or new building services have necessitated masonry removal and the installation of steel lintels to transfer loads bearing down from above.  Depending on the lintel’s span/size of opening below, the shoring work required to stabilize loads above can be complex and time-consuming.

ABOVE RIGHT:  NADAAA rendering of the new library study room, complete with new masonry opening to suit a service counter and clear site-lines from the adjacent library workroom, as required by the client’s program.  (see rectangular opening adjacent to the existing arched doorway).



ABOVE: Needle shoring was required to stabilize the loads above for work to proceed: masonry demolition and installation of the permanent steel w-section lintel for this 3.5 meter wide opening. “Needling” gets its name from the (in this case aluminum) structural sections penetrating the masonry, and resting on shores at either side of the wall.



ABOVE: Inspection of the building’s original sawn timber joists by a wood specialist uncovered the need to reinforce the floor assembly to achieve code compliance in many locations. This was accomplished either by sistering steel c-channels to each individual joists (thereby maintaining maximum ceiling clearance), or through the installation of a new steel girder below mid-span of the joists, as shown above.  (photo courtesy Peter MacCallam / The Daniels Faculty)



ABOVE LEFT: The wood consultant also identified the need for reinforcement of two monumental timber trusses that support the attic and roof above the central block on the top level.  Entuitive, our structural engineer, provided steel plate strapping, bolted to either side of the cracked bottom timber cords in response to the wood consultant recommendations.   (sketches courtesy Entuitive Corporation).  ABOVE LEFT: An original building section drawing dated 1873 shows the referenced space and trusses, which flank the central masonry tower.

Check out the  time-lapse construction video of  University of Melbourne’s Faculty of Architecture, Building and Planning from January 2013 – April 2014.  Only a couple more months until we get to see the completed building.

Additional  videos from different cameras on-site are also available on the university’s website.

Reinstating the Convocation Hall

Posted on June 16th, 2014 by tberesford

Posted under: construction


Phase I renovation of Knox College at 1 Spadina Crescent is progressing for the University of Toronto Daniels Faculty of Architecture, Landscape and Design.  Currently, demolition, restoration and structural work is underway at the former original Convocation Hall, which forms the east wing of the neo-gothic structure.  The monumental triple-height volume of the hall had been subdivided into three floors during  19040’s era alterations to suit the needs of the former Connaught laboratories.  The current renovation calls for a double-height space to be carved out of the second level, with intent to at least partially reinstate the grandeur of the original hall.


ABOVE: Ongoing demolition and structural retrofit to the fomer Convocation Hall at Knox College / 1 Spadina Crescent.  The original timber trusses have been exposed at level 03 as seen beyond.  The Level 03 floor structure in the foreground has been removed in preparation for shoring to support a new composite mezzanine floor.  Steel moment frames have been installed where some of the original timber trusses were removed.  The moment frames serve to stabilize lateral forces on the building while also retaining the open floor clearance at the level 03 mezzanine.  The level 03 floor seen beyond in the image above will be removed after the mezzanine slab is poured.  In the foreground, walls added in the 1940s that supported storage vault rooms and a stair are being removed.



ABOVE LEFT: Original sectional drawing of the Knox college convocation hall (1873). ABOVE RIGHT: The convocation hall in its original condition.  The timber hips shown below the timber trusses were removed when the hall was subdivided into three floors.



ABOVE: this image was taken from level 02, below the floor structure that was demolished in preparation for the new level 03 mezzanine structure. This space was also flanked by a stair and a series of storage vaults, both of which have been removed.  The bottom cord of the original timber truss in this zone has truncated/sawn in this location, and a pair of c-channel moment frames have been sistered to either side of the upper cord.

ABOVE: Sketch indicating retrofits to repair damaged timber trusses at the east end of the former convocation hall. The original trusses will be featured in this location upon removal of the existing level 03 wood floor structure. This sketch documents steel tension rods that have been installed to relieve forces on the existing timber ties (which have sustained cracks/damage over the years).  (courtesy Entuitive Corporation)



ABOVE: Detail showing steel rod reinforcement installed to reinforce the bottom ord of the original timber trusses. The level 03 floor structure on either side will be removed to open a double-height space, reminiscent of the original convocation hall.  Original hip support to the bottom of truss had been removed at the time of previous renovation.

Bridges at Cornell

Posted on June 12th, 2014 by tberesford

Posted under: Things We Like

NADAAA recently completed a project at Cornell University involving the modification of seven bridges to prevent  accidental or purposeful falling.  Each bridge has a unique structure, travel patterns and responds to specific conditions imposed by the landscape and built environments at each end.  Common to all of the bridges is the strategic use of high tensile strength wire mesh, from Jakob Rope Systems, that provides the necessary safety measures while maintaining unobstructed views to the scenic landscape.  The success of the project was greatly due to the collaborative efforts of the client, design team, contractor and manufacturers.

From the before and after photos of the suspension bridge, you can see the improvements to user experience  and functionality.






Information on the wire mesh and project background is also currently featured on Jakob’s website.
