Repairs to the roof structure of the concrete electrical vault at the Weldon Law Building required the off-site fabrication of a custom, non-conductive scaffold. Current spatial data was needed by the manufacturer to custom design and accurately fabricate the scaffolding to fit within existing spaces to tight tolerances. SDMM was contracted to capture the complex environment and deliver current, as-found 2d & 3d documentation of the vault and electrical equipment that was supplied to the Ontario-based manufacturer.
Seeking improved as-built documentation to provide to their consultants, the HIAA reached out to SDMM after hearing about our laser scanning services. Almost immediately, the Airport Authority recognized the larger benefits of leveraging the 3D modelling that SDMM’s Scan-to-BIM workflow utilizes to generate 2D drawings. Initially, SDMM was contracted to locate, scan, and model the sanitary line within the boundaries of the original Air Terminal Building’s center core, built in the ‘60s. In collaboration with M&R Engineering, SDMM delivered an existing conditions BIM to LOD300 standards along with updated 2d as-built drawings. Since then, SDMM have carried out additional Scan-to-BIM projects for the Airport Authority including the Domestic Departure Concessions Infill (2nd floor), and Domestic Arrivals Modernization projects.
Crombie REIT, one of Canada's leading national retail property landlords, was planning a large-scale cosmetic renovation and site redevelopment of the Avalon Mall in St. John’s, Newfoundland, and lacked reliable as-built records. A site of over 72 acres including commercial office towers, strip mall plazas, a parkade and 500,000+ square feet of leasable space, the Avalon Mall project required an accurate and comprehensive view of existing conditions that could be shared among the various consultants who were conceptualizing and planning future renovation options. Using Scan-to-BIM workflows, SDMM were able to accurately and efficiently capture the entire interior and exterior of the Avalon Mall, including the other buildings on the property, and create as-is BIMs for each of them.
BioVectra were set to embark on a refit of a recently acquired plant when they discovered that there were no as-built records to provide to their design-build team. Due to the complexity of the existing space, the required installation of new, larger equipment, and the multiple systems planned for the refit, BioVectra had a critical need for accurate information about the existing conditions of their facility. Working with BioVectra's project manager, Lindsay Construction, SDMM was contracted to scan and model a portion of the plant's interior including the architectural envelope, structural components, mechanical equipment and other plant features. As a result of SDMM's 3D deliverables, BioVectra was able to better define the scope of the construction project and share that information with their contractors.
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.
