The House Plan Shop: Crash-Testing Residential Construction to Improve Strength and Safety

You’ve heard of the crash-test dummies used to test the safety of automobiles. Home insurance companies recently began using this concept to “crash-test” residential construction. The goal is to provide insight, feedback and concrete evidence about home construction that will help devise new disaster-proof construction practices for home building. Home insurance companies can sponsor a test chamber that simulates severe weather conditions and the effect they have on model houses. For example, tests can simulate Mother Nature’s harshest weather conditions by inflicting gale-force winds, torrential rains, hail, fire and debris. The chief engineer for the Institute for Business and Home Safety, Time Reinhold, says “This is an opportunity to create demand for better construction.” The IBHS lab is designed to subject model homes to simulated weather conditions typical of a Category 2 or Category 3 hurricane such as 140 mph winds produced by fans, hail created by freezing water in different size molds, fire produced by blazing embers (burning mulch hurled by fans), open gas lines and burning shrubs and trees, and rain with up to 8” per hour produced by sprinklers.

 

The IBHS’s test facility debuted in October of 2010 with two test homes side-by-side. One was built to typical building codes used in the Midwest. The other one incorporated structural reinforcements and more durable materials. The results were impressive with the reinforced home suffering only cosmetic damage while the standard-code home collapsed in minutes.

 

The results were clear. It is worth investing in reinforced construction when it comes to durability and safety. For more information about cost and additional details, review this “crash-test” article.
