If the mitigation system is correctly installed and properly maintained, you can alleviate any concerns about using the building throughout the mitigation system\u2019s expected lifetime.<\/p>\n<p>Building size, construction, geographic location, and accessibility all impact pricing. Unit pricing for various VI mitigation methods can range widely, from less than $1 per square foot for simple ventilation approaches to as much as $70 per square foot for sites with significant access issues and higher construction labor costs. New materials combining construction applications, such as VI protection and waterproofing, have also entered the market in recent years. These products are more expensive per square foot individually, but provide combined savings to help meet technical goals while still remaining on budget.<\/p>\n<p>The details make the difference when developing vapor intrusion mitigation strategies, whether for new or existing construction. Building owners, operators and others responsible for indoor air inhalation safety are urged to retain a consultant experience in VI mitigation, as well as conduct a thorough evaluation of current and potential future building uses before investing in any mitigation approach.<\/p>\n<p>Looking for more information on methods and costs?
