1. Applicable Sections of the Code

 

IBC 504, IBC 718

 

2. Executive Summary

 

Tony Apfelbeck agreed to serve as the Building Fire TAC point of contact. The research portion of the scope of work is to be conducted by a third party vendor with building fire expertise. UF sent a solicitation to individuals and engineering firms specializing in fire related building performance and code issues. This resulted in the selection of a vendor. UF is currently creating a purchase order, upon which the vendor will be named and services will commence. Details are provided in Section 5 of this report. At this time the project is on schedule and within budget.

 

2.1. Description of Issues

 

·         Under the IBC, four story buildings with combustible concealed attic space (type V buildings) are permitted with no sprinkler system in the attic. Five stories are permitted in a pedestal type arrangement. Unsprinkled concealed combustible attic spaces did not exceed the three story limitation in the SBC.

·         Attic fire control with manual suppression is more difficult in taller buildings.

·         Draft stopping is the primary means of controlling fire spread in a type V unsprinklered attic.

·         The fire performance of the code specified attic draft stopping materials and installations should be reviewed to see if it is appropriately mitigating risk.

 

2.2. Recommendations for the Code

 

No recommendations at this stage

 

3. Scope of Work

 

·         Literature review and data gathering

o    Existing IBC code provisions on attic draft stopping

o    History of attic draft stopping in SBCCI and ICC

o    Current non-IBC approaches to  fire  confinement in  concealed combustible attic space (non-US codes)

o    Review justification (with respect to fire containment) for allowing increased height of type V buildings in IBC

o    Technical literature on fire testing of draft stopping materials and assemblies

o    Acquire incident data regarding attic fires in type V buildings Document challenges for manual attic fire suppression in type V buildings

·         Conduct a field assessment of attic draft stopping installations in existing type V buildings

·         Gap assessment: Determine if additional information is required to discern whether changes are necessary to the existing IBC attic draft stopping provisions.

o    If no additional information is required, develop either a code change for submission, or a support/justification document for the current code

o    If additional information is required, recommend a methodology for a phase II study to fill the information gaps identified. Phase II would be initiated in the following fiscal year

·          Produce a report that documents the approach and explains the results and implications for the Code

·          Present report/findings to the Commission’s Technical Advisory Committee and interest groups for review and feedback

 

 

4. Deliverables

 

·         A report providing technical information on the problem background, results and implications to the Code submitted to the Program Manager by June 15, 2014

·         A proposed scope of work for 2014-2015 funding cycle, if a phase II is warranted

·         A breakdown of the number of hours or partial hours, in increments of fifteen (15) minutes, of work performed and a brief description of the work performed.  The Contractor agrees to provide any additional documentation requested by the Department to satisfy audit requirements

 

5. Detailed Project Description

 

UF created a solicitation with the scope of work, deliverables and budget cap. The solicitation was sent to individuals and engineering firms specializing in fire related building performance and code issues. This produced five submissions from qualified fire engineering firms. A submission evaluation committee was formed consisting of Kurt Gurley, Tony Apfelbeck, Mo Madani, Bryan Holland (MCP, Building Official City of North Port), and Chris Weir (Deputy Chief, City of Port Orange, Florida Fire Chief’s Association). The committee members had a teleconference on February 28th to discuss the five submissions and select one as the vendor. Kurt Gurley contacted the selected vendor to clarify two issues, which were resolved to the committee’s satisfaction. UF is now in the process of creating a purchase order for this vendor. When the PO is finalized, the vendor will initiate the scope of work. The vendor will be named when the PO is issued.
