Frank Sienki6wicz Inspection Services City of Northampton Dear Mr. Sienkiewicz, I am writing in response to your request for a professional opinion on fire separation requirements for the Herold/Mikula apartment project in the Amherst Craftsmen building. The building seems to be Type 5 B construction fully sprink- lered (wet system) . Current use is Use Group B. The propo- sed conversion will result in a mixed use with Use Group R-3. The fire separation of I hour required between Use Groups R and B will be achieved through three different assemblies. The floor assembly between the first level Use Group B and the second level Use Group R spaces is currently, and is to remain, Type 4 heavy timber construction, a plank and timber assembly with a 1 hour classification per Factory Mutual. The assembly currently consists of nominal 8" x 14" beams planked with 2-7/8" mill decking covered with a nominal 1" hardwood finish floor. A layer of Class A Type NCFR Homasote and a new tonq_ue and qroove floor will be installed on top of this assembly during the conversion. Fire separation walls at the second level will be nominal 2" x 6" stud wall construction with a 5/8" Type X gypsum wallboard (or two layers of 1/2" ) screwed and taped on both sides. All doors in fire separation walls will be B rated. A 1 hour rated hung ceiling installed over the Use Group B areas of the second level will complete the separation. I believe that with the above measures this project will comply with the requirements of the Massachusetts Buildinq Code. Please do not hesitate to contact me with any concerns you may have regardinq this matter.
