A deletion to grease duct cleanouts and other openings (Section 506.3.8) has also been made in the 2009 IMC. Access doors on grease ducts may now be designed so that the use of a tool is permitted to open them. Previously, the code did not allow the use of a tool to gain access. click to continue

2009 IBC | Table 508.2.5 & Section 1604.8.3

A modification to incidental accessory occupancies (Table 508.2.5) has been made to the 2009 International Building Code (IBC). Parking garages and storage rooms are no longer regulated as incidental accessory occupancies. A modification to loading conditions on cantilevered decks (Section 1604.8.3) has also been made in the 2009 IBC. Previous code language had been modified to address the situation in which the load on the cantilevered portion of a deck span could produce uplift at the support remote from the support at the cantilever, which is consistent with the intent of the distribution of live loads in Section 1607.10. click to continue

Code Spotlight: Featured Articles

Reviewing Metal-Plate-Connected Wood Truss Submittal Packages
Light wood frame construction is widely used throughout the United States and in many places in the world. An estimated more than 60 percent of buildings that use wood frame construction have metal-plate-connected wood trusses. The wood trusses are most commonly used as framing members for roof construction, but they are also sometimes used in floor construction. Even buildings that use steel, masonry or concrete as the walls, columns and beams commonly use wood trusses for the roof framing when the building code allows. The building code typically limits use of light wood trusses to low-rise buildings. click to continue

Fire-Resistance-Rated Brick Veneer Exterior Walls
The 2009 ICC International Building Code (IBC) now contains four new exterior nonbearing wall design entries in Table 720.1(2) Rated Fire-Resistance Periods for Various Walls and Partitions. The IBC designates these designs as Items 15-2.1 through 15-2.4 for one-hour and two-hour fire-resistance-rated exterior walls finished with brick veneer. Items 15-2.1 and 15-2.2 describe one-hour and two-hour exterior walls constructed using thin brick veneer units attached as adhered masonry veneer. Items 15-2.3 and 15-2.4 provide details for one-hour and two-hour exterior walls finished with masonry veneer attached as anchored brick units. click to continue

Rebuilding Iraq: IBC Makes New Judicial Complex Safe and Secure

Since the 2003 invasion of Iraq, the international community has worked to improve and repair the country's infrastructure, much of which was destroyed during the conflict. Targets for repair or replacement have included the region's water supply, electrical system, transportation network, hospitals, government facilities, schools, housing and sewage treatment plants. As the region is being transformed, contractors have blended modern construction methods—including International Building Code (IBC) standards—with traditional construction methodologies in the face of some unique cultural and security challenges. click to continue

Metal Building Systems and the Code
Today, more than ever, owners and developers look to employ energy efficient, affordable building solutions to construct the next generation of industrial, commercial and residential buildings. Metal buildings systems offer industry a cost-effective and versatile alternative for projects that range from complex production facilities and distribution centers to retail stores, motels, schools and churches. As the application of metal building systems continues to rise, code officials and communities will want demonstrable proof that low-cost, energy-efficient metal building systems provide equivalent or better performance than brick and mortar counterparts in terms of safety and strength. click to continue

Accessibility in Recreation: Getting in the Game

Accessibility requirements primarily exist to allow equal access to all the places where people want to live, work and play. Current building codes address viewing events at recreational facilities with assembly seating requirements (including team and player seating); what the codes are branching out into is access to participation in the recreation activity itself. click to continue

Best Green Houses: Weaning Off Groundwater
Just outside Phoenix, a suburb called Fountain Hills boasts a centerpiece lake in which a giant nub shoots water as much as 562 feet into the air, on every daylight hour for 15 minutes. This columnar height makes the 40-year-old fountain the second tallest of its kind in the world, and it exemplifies old-school Arizona’s attitude toward water consumption: wasteful, arrogant, naive. click to continue

2010 Outlook: The Year ahead for Construction
Higher education was the one bright spot this year, and while there is hope that universities and hospitals will resume the multi-year campus plans they shelved last winter, these impacts are unlikely to translate into actual construction until the second half of 2010. Nonresidential construction, especially building construction, had a rough year in 2009. Unfortunately, 2010 will provide modest relief, at best. click to continue

Wall Art: Engineered Solutions for Aesthetic Earth Retention
Art and science truly combine in today's retaining wall systems. Civil engineers must design increasingly taller structures that not only support slopes, buildings, or roads, but also enhance the aesthetics of the project. The retaining wall can be a work of art itself, making an architectural statement; or it may disappear into the natural elements surrounding it, whether vegetation, soil, or rock. According to manufacturers, the most significant trends influencing the use of segmental, mechanically stabilized earth (MSE), gravity, and geocellular retaining walls include new project delivery and design methods, a focus on green or sustainable design, and wall aesthetics. click to continue

Trendy Living: A Closer Look at Multifamily Construction
Residential and multifamily construction projects, which have been hit especially hard over the last year or so, are being put on hold due to financial concerns. While some firms have seen a near complete halt to multifamily construction projects, other firms are still working on transit-oriented and mixed-use projects. click to continue

The ADA-Compliant Restroom
Make sure you're up to date on code requirements so you don't face liability issues later. Restrooms can lead to serious confusion when it comes to accessibility and universal design. "The most basic and least expensive way to determine if a restroom is accessible is to review the American with Disabilities Act Accessibility Guidelines and the American National Standards Institute's standard (ICC/ANSI A117.1)," says Jon Villwock, lavatory systems and washfountains product manager at Bradley Corp. click to continue

Are Houses Getting Too Tight?
The airtightness of the building envelope is an important key to understanding the performance of any new house. Uncontrolled air leakage can result in high fuel bills, failure of building components and increased builder callbacks. As a result, more and more time is being spent by the building trades sealing up new houses in an effort to reduce problems associated with air leakage. The question on many builders minds these days is; how tight should I be building my houses? After more than two decades of sealing up houses to make them more energy efficient, many people are wondering whether we've gone too far. The answer may be that we haven't gone far enough. click to continue

12 Major Trends in Library Design

Many academic planners assumed that the coming of the Internet would lead to the decline of the library as we know it. To the contrary, many academic libraries have experienced significantly increased patron use in recent years. click to continue

Building Valuation Data
The International Code Council is pleased to provide the Building Valuation Data (BVD) for its members. The Council publishes the BVD in an effort to provide the most efficient set of information for jurisdictions to use. The BVD is updated in February and August. The Council strongly recommends that all jurisdictions and other interested parties actively evaluate and assess the impact of the BVD table before utilizing it in their current code enforcement activities.
