Code Update: Significant Code Changes | |||
2009 IFC | Section 104.9.1 An addition to research reports and tests (Section 104.9.1) has been made to the 2009 International Fire Code (IRC). Research reports and results of tests used as a basis for approval are required to be provided to the fire code official. click to continue 2009 IRC | Section R301.2.1.1 A modification to design criteria (Section R301.2.1.1) has been made to the 2009 International Residential Code (IRC). The IRC now recognizes structural insulated panel (SIP) construction for high wind areas, bringing the list of design alternatives to six. The new ICC-600 standard for high wind areas has replaced the legacy code standard SSTD 10. Additional text clarifies that building elements not addressed in the referenced methods of construction need to comply with the provisions of the IRC. click to continue 2009 IBC | Section 403.5.5 An addition to high-rise buildings [luminous egress arkings] (Section 403.5.5) has been made to the 2009 International Building Code (IBC). Photoluminescent or self-luminous exit path markings are now required to identify the egress path in exit enclosures and exit passageways of high-rise buildings that house Group A, B, E, I, M, and R-1 occupancies. click to continue 2009 IMC | Section 304.10 and 506.3.8 A modification to clearance from grade for appliances (Section 304.10) has been made to the 2009 International Mechanical Code (IMC). A minimum clearance height for ground-supported mechanical equipment and appliances has been established. 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 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.
