Village Code Amendment Title 5, Chapter 1, Section 13 - Construction Type 3B for R-2 Multi Family Buildings
History
The Village of Orland Park has been requested to investigate the possibility of an amendment to the code for R-2 Multi-family dwelling unit buildings using the Type 3 construction types.
The construction classification of Type 3 by model definition is “the type of construction in which the exterior walls are of non-combustible materials and the interior elements are of any materials permitted by this code” IBC 602.3. The Village definition is “The type of construction in which the exterior walls are of non-combustible and masonry materials and the interior elements are of any materials permitted by this code.”
The discussion was based on the construction cost of steel non-combustible building going up after tariffs imposed on steel imports and raw materials. According to Mr. Joe Casucci, Chief Executive Officer of steel fabricator and erector FJM Ferro Inc., the tariffs announced in March have already caused American mills to increase mill pricing by almost 30%. These costs are passed along to steel erectors that construct not only to major steel building but also buildings utilizing a light gauge steel stud partitions.
Cost comparisons:
R-2 building 4 floors total area = 100,000 sq. ft. building for a Type 2A building = $14,723,000
R-2 building 4 floors total area = 100,000 sq. ft. building for a Type 3A building = $12,705,000
Cost savings for change in construction = $2,018,000 = 13.7% cost savings
These cost savings do not include the increase in steel cost for current U.S. Government tariffs.
The fire safety of the building would not be decreased and would still require fire rated construction for separations, exits, and building elements but would allow combustible materials to be encapsulated within the membrane of fire resistive materials. A full NFPA 13 system would be required and with properly designed spri...
