Development of the Grohmann Museum at the Milwaukee School of Engineering involved one of the most interesting building renovations in the city in recent years. It also involved installation of one of the most interesting roofs in the city.
The museum, at 1000 N. Broadway downtown, was developed within an 83-year-old structure that most recently served as a check clearing facility for the Federal Reserve Board. Under that use, the building had narrow windows and no public access. As a museum, it has been opened up to more natural light and to the public, thanks to the work of Uihlein-Wilson Architects and The Bentley Co. as general contractor.
The 38,000-square-foot structure was originally built in 1924 to house Metropolitan Cadillac, then owned by Glenn Humphrey, whose last name is familiar to many Milwaukeeans not only from his Cadillac and Chevrolet dealerships but also through his extensive philanthropy in the community.

With the increased desire for high-performance buildings and sustainable building products, green roofs have become a ‘growing’ roofing option in North America. Also known as a garden roof, vegetated roof, or eco-roof, these assemblies are simply a planted area on a flat or sloped roof. While conventional rooftop gardens usually consist of a few pots and planters, a green roof system can cover the whole roof area with the cultivation of plant life.
In Europe, extensive research and testing on how to waterproof green roofs started in the early 1970s. This work resulted in today’s waterproofing solutions, allowing durable and sustainable green roofs to grow in popularity. Although each green roof is unique and designed to meet multiple design and performance criteria, all green roofs contain the same basic components. The challenge for specifiers and designers is to determine which components are necessary and where they are should be located within the green roof assembly.

ADVISORY BULLETIN MARCH 2007
FLOOD TESTING
Upon completion of a roof installation, many owners wish to verify the integrity of construction prior to “taking possession”. Some designers and consultants specify that a flood test of the roof be carried out as a means of assuring that the roof has been properly built. The CRCA National Technical Committee does not support this practice, believing that flood testing is not a reliable quality assurance method and that the risks associated with flood testing far outweigh any potential benefits.
