Flying High Over Grand Parade, Halifax

Subsequent to the completion of Phase 4 of the Halifax City Hall restoration project in 2014, HRM desired to undertake a visual inspection of the exterior façade and roof to acquire baseline data for use in future maintenance planning and budgeting. With additional renovation work planned for the Grand Parade site, the City also wanted to supply consultants with accurate spatial information about the existing site topology and ground features (to supplement the 2d topographical survey that SDMM had completed previously). In lieu of traditional methods that would require expensive scaffolding to be erected and that would cause inconvenience to City staff and visitors to the site, an aerial survey and visual inspection using a purpose-built sUAS was carried out. The sUAS incorporated a commercial-grade UAV (or "drone") with a very high-end optical imaging system capable of capturing hundreds of high resolution photos rapidly and with extreme detail. In addition to supplying the close-range, high resolution photos of the entire City Hall structure, SDMM used modern photogrammetry methods to deliver a 3d photo-textured model of the building and Grand Parade from the image set for use in future planning work by the City.

Historic Site Experiences Modernization

The Alexander, a 240-unit multi-residential and commercial property, is being developed by Killam Properties at the site of the historic Brewery Market and Keith Hall. Prior to the start of design development, Killam’s project engineers, CBCL, advised them that the lack of current, reliable, existing conditions information for the adjacent historical building could negatively impact the design and should be addressed up front to avoid problems during construction. CBCL, already familiar with our Scan-to-BIM services from prior projects, asked SDMM to propose a solution and scope of work to deliver an existing conditions model plus 2d documentation of the site for use by the architects and engineers. Comprehensive 2d & 3d information about the entire site, including relevant portions of the vertical structures (existing buildings) affected by construction, view planes, and a topographical surface was delivered to Michael Napier Architects and CBCL serving as their basis for design and development of construction documentation.
