ICC cdpACCESS
AWC Desired Outcomes on International Building Code (IBC) Public Comments
Based on Public Comment Hearings
Sept. 30 – Oct. 5, 2015
Long Beach, CA

The ICC membership took Public Comment Hearing (PCH) action on proposed changes to the 2015 International Building Code (IBC) in Long Beach, CA, September 30 — October 5, 2015. The PCH results set the agenda for the cdpACCESS Online Governmental Consensus Vote. During a 2-week period starting sometime in late October (to be announced) cdpACCESS will be available for online voting. Validated Governmental Member Voting Representatives code officials will be voting online, determining the final action on these results.

AWC supports the following cdpACCESS actions on the 2015 IBC code changes. Please do not hesitate to contact AWC staff if you have questions or would like to discuss the AWC positions.

Please consider the urgent recommendation regarding G170-15, immediately below.

Code Change AWC Desired outcome on cdpACCESS vote Rationale
G170 Disapprove Technical errors discovered in Public Comment #2, which have significant impact on wood construction; this PC was mistakenly represented as editorial at PCH. The ICC Building Code Action Committee (BCAC) has issued a statement withdrawing support.
E97 Disapprove Reducing travel distance for buildings in high seismic and wind areas is not justified.
E105 Disapprove Increasing corridor fire resistance ratings for buildings in high seismic and wind areas is not justified.
FS7 As Modified Provides needed direction for the protection of light frame built-up stud packs and columns within fire resistance rated walls.
FS28 Disapprove Provisions would cause unintended consequences; fire wall loading criteria is being developed in the NFPA standard related to fire walls.
FS29 As Modified by Public Comment 1 Needed for effective high seismic design and will not significantly affecting the performance of fire walls.
FS30 As Submitted Provides for CLT fire walls in Types III and IV construction with appropriate ratings and protection of materials.
FS34 Disapprove Additional fire resistance rated joints are not justified for non-rated assemblies; imprecise language regarding the protection of voids.
FS42 As Modified by Public Comment 1 Good clarification of attic sprinkler protection criteria when draftstopping is omitted, among other improvements.
FS68 As Modified by Public Comment 1 Need clarification of charging language in section on fire resistance rated joints (makes no technical change).
FS135 Disapprove Unnecessary and has the potential to require retesting of products.
FS136 Disapprove Unnecessary and has the potential to require retesting of products.
FS139 Disapprove Unnecessarily shifts focus of requirements from ASTM E84 to NFPA 286.
FS150 Disapprove Imposes performance criteria on evaluation of house wraps which vary from current methods in ICC-ES acceptance criteria.
FS153 Disapprove ASTM E2556 contains thresholds that may inadvertantly limit options for water-resistive barriers.
FS159 Disapprove Required hygrothermal analysis is not justified for the conditions specified.
G128 Disapprove Restriction of building size in high seismic and wind areas is not justified.
G135 Disapprove Additional fire apparatus access roads are not justified.
G140 Disapprove Restriction of building size for wood construction types in high wind and seismic areas is not justified.
G144 Disapprove Reduces the open frontage area increases for only Types III, IV, and V construction without justification.
G152 Disapprove Increased fire resistance of occupancy separations for wood construction types in high wind and seismic areas is not justified.
G162 Disapprove Mandating 50 feet of side yard separation for Type V podium buildings is not justified.
G165 Pending The development of code criteria for tall wood buildings will be considered by the ICC Ad Hoc Committee on Tall Wood Buildings in anticipation of the next code change cycle.
G170 Disapprove Technical errors discovered which has significant impact on wood construction; BCAC has issued a statement withdrawing support; change mistakenly represented as editorial at PCH.
G171 Disapprove Restriction of building size in high seismic and wind areas is not justified.
G172 As Submitted Would provide the same criteria for exterior walls in Type III construction as in Type IV.
G175 As Submitted Adds specific reference to sheathing in FRTW framing provisions.
G177 Disapprove Specific conditions in the original proposal for the use of FRTW in exterior walls are unnecessary.
G179 As Submitted This editorial reorganization of independent heavy timber requirements and Type IV construction type provisions will aid in the application of both; companion G180 was approved on consent agenda.
G181 Approved as Modified by Public Comment 1 Adds needed provisions for protected concealed spaces in Type IV construction.
G182 Approved as Modified by Public Comment 1 Adds needed provisions structural composite and glued laminated timber components in Type IV exterior walls if protected and rated as required for CLT.
G184 As Submitted Clarifies minimum required thickness for CLT component of exterior walls in Type IV; removes minimum overall FRTW wall thickness requirements that were introduced with CLT provisions.
G190 As Submitted Provides needed performance-based alternatives for sound transmission design using engineering analysis.
G228 Disapprove Requiring fire fighting vehicle access to all four sides of Type V buildings of a certain height is impractical.
G236 Disapprove Proposed appendix containing an alternative building code for "resilient" construction is not justified.

AWC Public Comment #2 – requests Approve as Modified

  1. On October 4th, the American Wood Council (AWC) conducted a successful ASTM E119 fire resistance test on a CLT wall at NGC Testing Services in Buffalo, NY. The wall, consisting of a 5-ply CLT (approximately 6-7/8 inches thick), was covered on each side with a single layer of 5/8" Type X gypsum wallboard. The wall was loaded to the maximum load attainable by the NGC Testing Service equipment. The test specimen lasted 3 hours, 5 minutes, and 57 seconds (03:05:57). The US CLT Handbook project provided funding for this fire test.

Additional information:

  • In September 2015, a CLT floor/ceiling penetration firestop test was performed at Southwest Research Institute (SwRI) in accordance with ASTM E814-2013, Test Method of Fire Tests of Through-penetration Firestopsas referenced by the 2015 International Building Code. The CLT floor/ceiling assembly contained three openings. Two of the openings contained PVC pipes, and one contained bundled insulated power cables. The firestop systems tested with these penetrations are commonly available. All three of the penetration firestop systems achieved F-ratings and T-ratings of 2 hours. A full report of the test will be available in the future.
  • The following video was prepared based on AWC's original committee proposal. The public comment modifies the proposal, but much of the video is still informative and applicable. Please see G165-15 PC2. Click here to view the video.
