Historic Preservation + Restoration Design

Engineering Preservation That Lasts

The most successful renovation and preservation projects are engineered with structural expertise, code compliance, and historic elements in mind.

KCI, formerly McLaren Engineering Group, brings creativity and sensitivity to the analysis, repair, redesign, and preservation of significant structures and sites across the country. From theaters, civic buildings, schools, and libraries to transportation facilities, facades, waterfront assets, and other existing structures, our team helps owners, architects, developers, institutions, and public agencies restore, adapt, and extend the life of historic buildings and places.
