Our practice is especially well positioned to support clients with potentially “messy” or complicated restoration and capital improvement projects. We can help you plan, design and budget for a positive outcome.
We’ve also worked under the constraints of a variety of difficult terrains and weather conditions, including regions that experience extreme seismic and wind events. Furthermore, we’re well-versed in the mitigation of salt spray corrosion in coastal construction.
Geographic reach is complemented by wide-ranging experience with the modernization of a variety of building typologies with specialized industry-specific requirements, including residential developments, manufacturing buildings, aviation infrastructure, civic and cultural landmarks, healthcare facilities, schools, and office towers.


We analyze future operational and maintenance requirements and how property value could be impacted. We anticipate the systems that will need to be upgraded and modernized over the building’s lifespan, and help you plan for future required investment.
The success of a building modification is evaluated according to each solution’s cost-benefit analysis over time. We consider the project’s physical buildability and financial feasibility.
Our structural engineers, façade architects, and vertical transportation consultants pre-plan for procurement to ensure that the right technologies and system typologies are identified and secured for anticipated building systems interactions. Only early and regular dialogue with suppliers and contractors will ensure the optional choice of systems. Cost, schedule, site logistics, material availability, market conditions, and construction phasing are all considered in determining the right systems for a given project.
