New Building Code Changes, Joplin, Missouri
After being devastated by a powerful tornado, Joplin builders and contractors will be required to perform additional steps to protect their buildings against strong winds. Among the building codes changes being adopted by the city of Joplin, Missouri, wood rafters and wood trusses will be required to be installed using mechanical anchors. Those mechanical anchors will be required along with block foundations embedded in concrete, and anchor bolts installed at 4 foot spacing instead of the usual six foot.
However, city officials understand that these changes will not prevent home destruction during an EF-5 Tornado; they know that code provisions will enhance and promote safer building in the city. These code changes will be enforced starting on November 2011. An average estimate of this changes is sought to be in the range of $100- $200 when they rebuild. The city of Joplin was devastated on May 22nd by a large tornado. Another way of protecting life and property is by building safe rooms. A safe room is another economical alternative that can be used following FEMA standards. Many builders in the Missouri area preferred to build using Insulated Concrete Forms, stronger than traditional construction that provides the protection of a shelter along with energy savings and ease of construction.
City officials say these new codes will ensure that homes can withstand wind speeds of around 130 miles an hour.
