by: Ronald L. Geren, AIA, CSI, CCS, CCCA, SCIP Gypsum board has been an important part of the construction industry for more than 100 years. Its humble beginnings started in the late 1800s as ÏSackett Board, named for Augustine Sackett, one of the inventors of the early gypsum product. Sackett Board consisted of Plaster of Paris between two layers of felt paper. The board was 1/4 inch thick and 36 inches square with exposed edges. Although not suitable as a finish product as is todays gypsum board, Sackett Board made an excellent base for gypsum plaster. In 1910 the evolution of gypsum board took another step forward when a process for wrapping the exposed edges was implemented in manufacturing.

ÏQuality is never an accident; it is always the result of intelligent effort. John Ruskin, author and critic of art and architecture
by: Ronald L. Geren, AIA, CSI, CCS, CCCA, SCIP The topic of construction documents was addressed in a previous article ofThe Code Corner1. However, the message of that article was the broad subject of construction documents by building code definition and did not broach methods of how to actually communicate code-related information in the documents. This article and a companion article in RLGAsKeynotes2series will expand on the previousCode Cornerarticle by introducing methods to better communicate building code compliance within the drawings and specifications. Plan reviews can take a few days up to several weeks or months depending on the size of the project.
By Ronald L. Geren, AIA, CSI, CCS, CCCA, SCIP Passive fire protection has been a significant component of building codes since the publication of the first Building Code recommended by the National Board of Fire Underwriters (NBFU) in 1905Óeven Nero established some form of passive fire protection in Rome after it burned in 64 A.D. Passive fire protection is the use of building materials to limit the effects of fire on a building or to contain the spread of fire within a building or between separate buildings.
By: Ronald L. Geren, AIA, CSI, CCS, CCCA, SCIP According to the Glass Manual, published by the Glass Association of North America (GANA), glass has been around for more than 4,000 years. Glass allows daylight in and allows building occupants to view the outside world while still maintaining an envelope to separate inside from outside. However, the use of glass in buildings presents issues that must be addressed, such as energy efficiency, fire protection, and life safety. The International Building Code (IBC) covers all three of these areas. Read More...

Geren, AIA, CSI, CCS, CCCA, SCIP One hundred and sixty years ago, Elisha Otis invented the first braking mechanism for the elevator, which made vertical travel within a building feasible and safe. A little over forty years later, the gearless traction elevator was developed, which allowed movement in buildings of significant height. Thus, along with the advent of inexpensive materials and advanced engineering and construction methods, the automatic elevator became a pivotal step that led to the surge of high-rise construction in the United States. Since its introduction, the elevator has seen numerous advancements, but its purpose remains the same: moving people between floors of multi-story buildings efficiently and safely.

There are at least two building material systems which are indigenous to the Desert Southwest and which are still in use today, even in commercial work. The period of time well look at is up until the end of the Civil War, at which time the products of renewed industrialism were brought to the area by railroad. The systems in question are rammed earth and adobe block.
The use of an indigenous building material in a locale owes its popularity to its abundance of raw material, its ease of production, its structural properties, and its ability to effect a comfortable habitable space.
