This guide is to allow a user to assessgeneral moisture concerns, as well as the potential need forfurther assessment or other actions that may be appropriate th

For purposes of this guide,the initialism “VMA”or“Visual Moisture Assessment” is usedinterchangeably with this guides full title.1.2 Purpose LimitationsWhile a VMA may be used tosurvey for readily identifiable moisture affected materials andphysical deficiencies

7、 conducive to elevated moisture, the VMAis not designed to serve as comprehensivesurvey for thepresence of moisture affected materials and physical deficien-cies conducive to elevated moisture in all or most areas in acommercial building. It is not intended to reduce or eliminatethe risks that eleva

8、ted moisture may pose to the subjectbuilding or its occupants.1.3 Considerations Beyond This ScopeThe use of thisguide is strictly limited to the scope set forth in this section.Section 12 of this guide identifies, for informational purposes,certain physical conditions (not an all-inclusive list) th

9、at mayexist at a property and certain activities or procedures (not anall-inclusive list) that are beyond the scope of this guide butmay warrant consideration by users. The need to investigateany such conditions in the providers scope of services shouldbe evaluated based upon, among other factors, t

10、he nature of theproperty and the reason for conducting the VMA. The scope ofsuch further investigation or testing services should be agreedupon between the user and the provider as additional services,which are beyond the scope of this guide, prior to initiation ofthe VMA process. The responsibility

11、 to initiate work beyondthe scope of this guide lies with the user.1.3.1 Sampling for suspect fungi and other forms of biologi-cal growth is a non-scope consideration under this guide.1.3.2 Sampling or otherwise measuring for moisture is anon-scope consideration under this guide.1.4 Organization of

12、the GuideThis guide has 13 sectionsand three appendices. Section 1 defines the Scope. Section 2 isReferenced Documents. Section 3 is Terminology.
