The flesh, alas, is wearied.
It has been estimated that a piece of masonry falls off a building in the United States at least once every three weeks, on average.
--Grimm, "Preventing Facade Failures", Civil Engineering, March 1999
The facade of a building is generally defined as the front face and is usually distinguished from the other sides by more prominent architectural detailing and design. The facade and the other sides of the building are collectively referred as the Building Envelope. Pedestrians are increasingly being hurt or killed by falling pieces of exterior building facade. Many cities, most notably Chicago, now have facade inspection ordinances in place to protect the public.
Lawson Elser, Inc. has extensive experience with investigation of facade and building envelope construction for both historic and non-historic buildings. This experience includes construction consisting of brick masonry, stone, terra cotta, concrete masonry, pre-cast concrete, cast-iron, and manufactured curtain-wall systems.
With information from a Structural Investigation, the condition of any building skin can be established and repair schemes developed to correct deficiencies and deterioration.
