SUBJECT: BILL 270 (DRAFT 3)
The Department of Public Works ( "DPW ") provides the following update and material
regarding passage of Bill 270, Draft 3.
I. ADOPTION OF BUILDING CODE REQUIRED BY STATE LAW
Bill 270, Draft 3, would change the Building Code by adopting the 2006 International
Building Code (2006 IBC), along with a number of state and county amendments.
The county is required by state law to adopt a building code using model codes and
standards, such as the 2006 IBC, no later than two years after the adoption of the state
building code. The state building code was adopted in 2010, and adoption of Bill 270 will
bring the county into compliance with the state law.
II. RECENT PUBLIC WORKSHOPS REGARDING BILL 270 CONDUCTED
The DPW recently conducted two workshops. The first, on Tuesday, September 6 at the
West Hawaii Civic Center, Community Meeting Hale in Kailua -Kona from 4 p.m. to 7 p.m.
The second, on Wednesday September 7 at the Aupuni Center Conference Room in Hilo
from 3 p.m. to 6 p.m. These recent workshops were in addition to:
• the public meeting conducted by DPW on October 2, 2010 (Hilo, approximately 36
people in attendance); and
• the public meeting conducted by DPW on October 28, 2010 (Kona, approximately
11 people in attendance); and
• at least a half a dozen meetings between DPW staff and individuals from the
public-to address questions or concerns; and

III. RECENT PUBLIC WORKSHOPS
During the workshops, County staff from the Building Department again explained and
clarified proposed changes to the Hawai'i County Building Code. The primary presenters
during the most recent workshops were:
• Neil Erickson, Architect and Plans Examiner for DPW.
• Ray Tanabe, Meteorologist in Charge of the NOAA National Weather Service
Forecast office in Honolulu.
• Gary Y.K. Chock, S.E., author of Modeling of Topographic Wind Effects in Hawai'i
and Modeling of Hurricane Damage for Hawai'i Residential Construction and
Topographic Wind Speed -up and Directionality Factors for Use in the City and
County of Honolulu Building Code and the Multi- Hazard Pre - Disaster Mitigation
Plan for the City & County of Honolulu; former president of the Structural
Engineers Association of Hawai'i; and member of the State Building Code Council.
Neil Erickson compared administrative changes to the current code, chapter 5 regarding
wind -load, partially enclosed structures, emergency preparedness, specifications & plans,
violations, permits, and pre- approved package homes. Mr. Erickson's presentation
materials from the most recent public workshops are included as Attachment 1.
Ray Tanabe briefed the audience on "Central Pacific Hurricane Center and 2011
Hurricane Preparedness." Mr. Tanabe addressed the history of tropical cyclones, tropical
cyclone impacts, and typical "myths" regarding tropical cyclones. Mr. Tanabe also stated:
1) all islands in Hawai'i are at equal risk; 2) there is a 1 out of 15 chance of hurricane
winds somewhere in Hawai'i every year; 3) the islands do not have enough land mass to
draw energy from a tropical cyclone to weaken the storm system. Mr. Tanabe's
presentation materials from the most recent public workshops are included as Attachment
2.
Gary Y.K. Chock, S.E. spoke on "Hawaii Wind Design Requirements for Hurricanes." Mr.
Chock explained how technical committees collaborated in the creation and evolution of
the technical language of the building code and ASCE7 in regards to wind design. Mr.
Chock also addressed the obsolete calculations and formulas relied upon by the Uniform
Building Code and the best modern methods of calculation relating to wind design that are
a part of the IBC. According to Mr. Chock, the national model codes have adopted
accredited national standards like ASCE 7 so that detailed technical provisions can be
developed in a non - political environment and be subject to peer review by those with
nationally recognized expertise. The International Code Council adopts such standards
by reference and sometimes extracts key portion of text to include in the codes. Mr.
Chock's presentation materials from the most recent public workshops are included as
Attachment 3.
