Mature Office Parks Along Olive Boulevard
The Olive Boulevard corridor in Creve Coeur holds some of the oldest continuously occupied commercial office space in West County. Buildings from the late 1970s and early 1980s on concrete or pre-cast deck were originally roofed with built-up bituminous systems, some of which have been recovered once or twice with single-ply membrane on top of the original BUR. Multi-layer recover systems create complexity: each added layer reduces the drainage slope, increases the dead load on the deck, and creates more potential leak paths between layers.
When we inspect a Creve Coeur Olive Boulevard building with this kind of history, we core the field and the parapet zones to understand what is under the surface. A building carrying three roof systems on a deck rated for one may need a full tear-to-deck project, and that discovery is better made in the inspection phase than after mobilization.
