ICC Rolls Out Cloud-Based Code Development Process
International Code Council Members and others with an interest in public safety in the built environment have begun to use the first version of cdpACCESS—the new, cloud-based tool built exclusively for ICC's code development process (cdp). Once referred to as remote voting, cdpACCESS is much more than that. With cdpACCESS, you can create code change proposals and submit them online. Code change proposals for ICC Group C for the International Green Construction Code are due by January 10. Go to cdpACCESS.com to experience cdpACCESS.
“The ultimate goal is to provide a superior way to develop codes and increase participation in code development,” said ICC CEO Dominic Sims, CBO. “We are confident that code development participants and public safety will benefit from cdpACCESS.”
In the coming weeks additional features will be rolled out in stages based on the steps in the code development process. These features will include:
- Online collaboration with one or many colleagues;
- View, download and print the Code Change Agenda;
- Online submittal of floor modifications at the Committee Action Hearing;
- Online vote on assembly floor motions following the Committee Action Hearing;
- View, download and print the Report of the Committee Action Hearing;
- Online creation and submittal of public comments to the Committee Action Hearing results;
- View, download and print the Public Comment Agenda; and
- Online voting on proposed code changes/public comments following the Public Comment Hearing.
All ICC Members are eligible to vote online on assembly floor motions. Only Governmental Member Voting Representatives and Honorary Members can vote on proposed code changes/public comments. cdpACCESS allows you to participate in code development from a computer or tablet, when you cannot attend in person.
ICC has extensively tested cdpACCESS on a wide variety of Windows and Apple computers and the iPad. cdpACCESS is designed for use on Internet Explorer, Firefox, Safari and Chrome. Internet Explorer version 7 and earlier versions are not supported. Analysis of ICC website traffic has shown this will affect a very small percentage of users.
cdpACCESS is now the way to submit code changes to the International Green Construction Code (IgCC) for the 2014 Group C Committee Action Hearings, April 27–May 4, in Memphis, Tenn. To provide participants additional time to become familiar with cdpACCESS, and due to the year-end holidays, ICC extended the Group C online code change submittal deadline to Jan. 10 from Jan. 6. Online voting on assembly motions made at the Committee Action Hearings will take place after hearings.
Support for cdpACCESS includes help by phone and email to answer questions, receive comments and suggestions, and report any system errors. The toll-free cdpACCESS hotline is 855-ICC-CDP-1 (422-2371); email can be sent to cdpACCESS@iccsafe.org. A schedule of free cdpACCESS webinars can be viewed at iccsafe.org/cdpACCESS.

CTBUH Affirms One World Trade Center Height
The Council on Tall Buildings and Urban Habitat convened its Height Committee on November 8th in Chicago to evaluate its criteria for determining the official height of buildings, and to rule on the official height of One World Trade Center in New York.
The Height Committee has reached a consensus that One World Trade Center’s height to its architectural top is 1,776 feet (541.3 meters).
Note, because One World Trade Center is still unfinished and has not received its certificate of occupancy, it cannot yet enter CTBUH rankings as a “completed building,” but its height is no longer in dispute.
This determination was made through examination of design and construction drawings, and continued through dialogue among the Height Committee’s 25 members.
“We were very satisfied with the detailed information presented by the team, in particular, that which affirmed that the structure on top of the building is meant as a permanent architectural feature, not a piece of functional-technical equipment,” said Timothy Johnson, Chairman of CTBUH and Design Partner at NBBJ.
“The design of One World Trade Center, as explained to us, reinforces its role as a symbol of resurgence on this important site,” said CTBUH Executive Director Antony Wood. “In particular, the spire which holds the beacon light, shining out at the symbolic height of 1,776 feet, is especially poignant – echoing the similarly symbolic beacon atop the Statue of Liberty across the water.”
New Edition Of The North American Specification For The Design Of Cold-formed Steel Structural Members Is Published

Tall Buildings in Numbers: Vanity Height – The Use-less Space in Today’s Tallest Buildings
CTBUH has investigated the increasing trend towards extreme spires and other extensions of supertall (300-meter-plus) buildings that do not enclose usable space, and created a new term to describe this – Vanity Height, the distance between a skyscraper’s highest occupiable floor and its architectural top, as determined by CTBUH Height Criteria. Here are some key findings of the study:
- At 244 meters, the vanity height of the Burj Khalifa, Dubai, UAE, could be a skyscraper on its own – in fact, it would be Europe’s 11th-tallest building.
- The Burj Al-Arab, Dubai, UAE, has the greatest vanity ratio of any supertall building – 124 (39 percent) of its 321 meters is devoted to non-occupiable space above the highest occupiable floor.
- Without their vanity height, 44 (61 percent) of the world’s 72 supertalls would measure less than 300 meters – thus losing their supertall status.
- United Arab Emirates clocks in as the nation with the most “vain” supertall buildings, with an average vanity height of 19 percent.
- New York City, USA has two of the tallest 10 vanity heights, and is set to gain a third with the completion of One World Trade Center in 2014.
- According to CTBUH Height Criteria regarding telecommunications towers, a 50 percent vanity height would deem any structure a “non-building.”
- The “vainest” building overall in the CTBUH database, although not a supertall, is the Ukraina Hotel in Moscow, Russia – 42 percent of its 206-meter height is non-occupiable.

Tilt-Up Concrete Association Releases New Temporary Wind Bracing Guideline
MT. VERNON, IOWA – The Tilt-Up Concrete Association (TCA) – an international nonprofit organization that serves to expand and improve the use of Tilt-Up as the preferred building system – has announced the release of a revised guideline on Temporary Wind Bracing of Tilt-Up Concrete Panels During Construction.
According to Jim Baty, Technical Director of the TCA, the guideline is intended to provide a standardized method for the design and erection of a temporary bracing system for use during construction of a Tilt-Up structure. The current OSHA requirement requires that Tilt-Up concrete panels be temporarily braced to prevent panels from overturning or collapsing during the construction of a Tilt-Up structure. Since OSHA does not specify how to prevent Tilt-Up wall panels from overturning or collapsing, the TCA developed a temporary bracing guideline for use by the construction industry.
“The 2012 edition of the TCA Wind-Bracing Guidelines is a combination of technological progress in this industry and reassurance for the performance of these systems,” said Baty.
Baty noted that the industry was challenged when ASCE 37 identified it would change to adopt ASCE 7 pressures as it established the concern that bracing schemes may be under-designed for the resulting wind conditions. However, he noted, TCA’s engineering experts have been able to confirm that Tilt-Up bracing systems are sufficiently designed with today’s standards.
“This confirmation permitted us to move forward with recommendations for response design recommendations on slab thickness and integrating helical ground anchor systems to this more robust version,” he said.
The original TCA Bracing Guidelines, published in September 1994, suggested a temporary bracing design based on a minimum uniform lateral wind pressure of 10 psf., applied over the entire panel area. This was based on a 40-year history of bracing panels that were for the most part, shorter than 30-feet tall. TCA revised the document in 1998 to incorporate the analytical procedures contained in ASCE Standard 7-95, Minimum Design Loads For Buildings And Other Structures. This ASCE standard forms the basis for calculation of wind forces used in the design of wind force resisting systems in completed structures. The wind load provisions of section 6.0, ASCE 7-95 were followed in the design of temporary bracing for Tilt-Up panels during construction.
The application of ASCE 7-95 resulted in an applied lateral wind pressure that varies over and increases with the height of the panels. The 1998 guideline used a construction period wind speed of 70 mph as a minimum in the design of temporary bracing. This was based on a basic wind speed of 90 mph, with a fifty year mean recurrence interval and multiplying it by 0.78 to convert it to a construction period wind speed of 70 mph with a five year mean recurrence interval. This method also incorporated the 3-second gust speeds reported by the national weather service and other weather information services.
In 2005, TCA revised its 1998 wind-bracing guide to incorporate the provisions of SEI/ASCE 37-02, Design Loads On Structures During Construction. The SEI/ASCE 37-02 standard incorporates the design wind load requirements of the ASCE 7-95 standard, using a basic wind speed of 90 mph. For construction periods up to one year, the SEI/ASCE 37-02 standard specifies the use of an adjustment factor of 0.8 to be applied to the basic 90 mph wind speed. This adjustment results in a 72 mph construction period design wind speed, which is the wind speed recommended for design of the temporary bracing system.
The 2012 edition continues to base its design loadings on SEI/ASCE 37-02, however, the wind loadings are now based on ASCE 7-10 provisions. ASCE 37-02 will adopt the ASCE 7-10 wind provisions in the next revision to the publication. In addition, it is very likely that many, if not all local building codes, will endorse ASCE 7-10 in the near future. As such, the TCA decided to endorse ASCE 7-10 as the standard for temporary bracing of Tilt panels during construction.
The major changes to wind load provision of ASCE 7-10 include:
- Introduction of new wind speed maps to be used with a 1.0 load factor for LRFD design
- A 0.6 load reduction factor for ASD design
- Re-introduction of Exposure D in hurricane prone Regions

New Report from IBHS Evaluates Building Codes in 18 Coastal States
The Insurance Institute for Business & Home Safety (IBHS) released a new report which provides an analysis of residential building codes in the 18 hurricane-prone coastal states along the Gulf of Mexico and the Atlantic Coast. Building codes are intended to increase the safety and integrity of structures, thereby reducing deaths, injuries and property damage from hurricanes and a wide range of other hazards.
Rating the States: An Assessment of Residential Building Codes and Enforcement Systems for Life Safety and Property Protection in Hurricane Prone Regions is the first of its kind, state-by-state assessment of individual state performance in developing and promulgating a residential building code system, which uses modern building codes, coupled with strong enforcement related activities to enhance the protection of homes and families.
“The report goes beyond just evaluating each state’s code system,” said Julie Rochman, IBHS president and CEO. “The report offers each state the detailed information and tools it needs to improve its building code process to better protect its citizens. It also gives interested citizens useful information so that they can understand the need for, and demand, better building codes.”
The report combines IBHS’ engineering expertise and regulatory research to examine the three main elements of a state’s building code system:
1. Code adoption and enforcement – Statewide mandatory code adoption and enforcement are the primary elements to require that the minimum standards of codes are utilized.
2. Code official training and certification - Code official training and certification are part of the regulatory scheme to ensure that code officials are properly educated, trained and tested in order to correctly enforce building codes.
3. Licensing requirements for construction trades - Licensing requirements for construction trades ensure that contractors and subcontractors are familiar with the sections of code that impact them, that
