Assessing buildings and other structures to identify underlying conditions and mechanisms leading to distress, whether you are looking for maintenance recommendations or solutions to specific problems.
Prepare sketches or full construction documents for implementation of repairs and maintenance needs, with a focus on addressing root causes and prolonging the service life of existing buildings. We also serve as building enclosure consultant for architects on both existing buildings and new construction projects.
Provide expert opinions and dedicated investigation as required to support attorneys, developers, contractors, and owners during construction defect claims or active litigation.
Oversee all aspects of the building enclosure during construction. We engage with architects, developers, contractors, and owners and can tailor services as needed based on construction complexity and duration.
Facade inspections and filings with the City of Boston for buildings over 70 feet tall, as required every five years.
We have licensed drone pilots on staff to support projects and help with any aerial photography or videography needs. Drone photography can significantly reduce the inspection budget over traditional access methods. As an added benefit, images and videos can be used by clients for marketing, planning, design, or other uses.
