Civil engineers who work on historic preservation projects often deal with materials and systems that are no longer widely used and have little documentation.

The United Kingdom’s Main Mill at Shrewsbury Flaxmill Maltings, the first cast-iron framed building, was restored using a bottom-up, first-principles approach.

A collaborative, goal-first approach played a major role in a historic facade preservation project for Wellesley College’s Science Complex.

The U.S. Army Corps of Engineers buttressed and raised both earthen structures, constructed a new emergency spillway, and improved the foundations of one dam.
