When the 50-year old building began showing signs of concrete spalling and exterior degradation, the owner became concerned. Repairs would need to match a unique concrete lava rock aggregate surface. In addition, locating points of failure along a tall façade typically requires either scaffolding the building or hanging window washing type rigging for inspectors to get close to the walls. Instead Hilliard Architects implemented a safer, cheaper solution: a remote controlled drone.
We captured video of the entire building surface, creating a visual map and index of damaged areas. Our deliverable was a comprehensive report that located cracking / spalling / rusted rebar and provided specifications for patching concrete, and a construction cost estimate.
Our client believed that the clarity of the report would translate into a tight set of bids for the repair work.
