Set in the North End of Halifax, ISL Web Marketing's new head office is a three-and-a-half-story, 8,100-square-foot office space. The client expressed interest in the Tilt-Up method of construction, which served the project well due to the high density location of the land acquired for the project. The building site allowed for only a 50 feet by 50 feet footprint in which to work. The building lift was done within three feet of a neighboring building.
By using a panel as a fire separator, Tilt-Up allowed for the building to go up within this confined space. The street could not be closed during the lift because it was home to a fire station, so the lift continued with one lane closure and traffic control measures. By melding Tilt-Up construction and traditional structural steel clad methods together, the client was able to achieve a unique look to the structure and have an efficient construction timeline. Additionally, the use of BIM modeling using REVIT provided the designers of the building an opportunity to check for interference between the temporary panel bracing and the structural steel floor framing.
For most buildings, the panel bracing falls well below the diaphragm and allows for simple removal of braces once the panels are fully connected to the decking. With ISL's complex geometry, the second and third floor structural steel floor framing was required to be built around the temporary panel bracing until the composite deck on the third floor was fully connected, poured, and cured. Only then could the temporary bracing be removed and the second floor composite deck be installed.
