UMass Project Manager:
The project will provide labs, lab support, and offices for 20 faculty (9 chemists and 11 physicists) and approximately 130 bench positions. The building will include 44,255 nsf, consisting of lab and lab support space, offices/conference space, and building support.
The PSB is planned to be approximately 82,500 gsf of new construction on three levels. The building will have a basement, accommodating physics laboratories with high bay capacity sitting on foundations that will telegraph very low levels of vibration.
Spray on fireproofing on I section steel columns
SFRM, Sprayed Fire-Resistant Material. Used for insulation of high temperatures during a fire to protect the steel from a chance of failure.
Most SFRMs are made from cement or gypsum and mixed with other smaller material such as mineral wool, quartz, perlite, and vermiculite.
Sprayed Fire-Resistive Material is the passive fireproofing method any steel column or beam from intense fire. Its main goal is to stop the heat from transferring through the cement or gypsum base material in order to stop the steel structure from failing. This is achieved by thermally insulating the structural members well below failure point.
SFRM’s are cement and gypsum based materials making them inorganic. Being inorganic it makes the spray on mold resistant. Many SFRM is made with other materials such as mineral wool, quartz, perlite, or vermiculite. Cement and gypsum are the main materials because once the spray one dries the materials harden up not only protecting the steel from fires but also reinforces the structure.
There are regulations on SFRM base on ASTM E119. ASTM or American Standard Test Method is mandatory to ensure the safety of the material and buyer to the public.
The SFRM used in the UMass physical science building is called Cafco Fendolite, it is produced by a worldwide company called Isolatek International. Cafco is made with cement as its main ingredient in order to ensure maximum strength and fireproofing. This product is the most widely used high density SFRM in construction for the past 30 years.
This white spray is called SonaSpray "fc". It's only on the top floor where heavy machines are being placed. It is a spray that reduce noise. It is a Class 1 fire rated.
SonaSpray is a acoustical spray that is typically sprayed on the ceilings. This spray is the most generally used in the commercial market to reduce noise ranging from 65-90% reduction. This material will basically stick to any construction surface. It has been accredited tested be a NVLAP lab to an ASTM C-423 to a class 1 fire rated protection.
• Steel structure is protected from intense heat during a fire.
• Prevents failure in structural support.
• Spray on form for the steel beams making work easier.
• Some spray over electrical circuits to keep temperatures below 140°C to stay operational.
• Modern day spray on is now asbestos free, which causes cancer.
• Lightweight mixture providing reduce dead loads in building.
• This material used in the PSB is going to have reduced materials but also have much higher application efficiency to remain a high case product.
• Increase of flexural strength to combat the harsh environments of chemical facilities.
