Preservation Technology

The Preservation Technology Studio understands the opportunities presented by the continuing use of existing and historic buildings. By blending good design, new technology, and sustainable practices, we extend the service-life of these structures and their character-defining components. Because we understand historic building materials and their changing uses over time, we are able to respond to our projects quickly, and to guide sound evaluations and repair decisions.

Material Conservation & Condition Assessments

Our conservators are experienced professionals with knowledge of building materials, deterioration mechanisms, and repair techniques. Our collective experience ranges wide—materials science and conservation, carpentry, structural engineering, and architecture—yielding a multi-disciplinary approach to our condition assessments and material analyses. Our shared understanding of historic buildings means better decisions about how to do condition evaluations and repairs. Our approach is a sustainable one, emphasizing treatments that are reversible and don’t impact the rest of the structure or the environment.

We are able to inform our clients about simple maintenance planning and service-life; preparing thorough historic structure reports, HABS documents, and conditions reports; and determining conservation-focused rehabilitation schemes. We have worked on projects with stone, terracotta, concrete, wood, brick, adobe, building metals (including steel, aluminum, monel, copper, and bronze), paint, and various interior finishes. Our value lies in our ability to adapt to the conditions of your project, and to provide quality information and solid direction.
