Guideline for Condition Assessment of the Building Envelope
|Publication Date:||1 January 2014|
SCOPE AND INTENT
The intent of this standard is to provide a guideline and methodology for assessing the condition and performance of existing building envelope systems and components and identifying problematic and dysfunctional elements. It applies equally to a building ' s envelope or portion whose primary purpose may be to serve as the supporting structural system of the building. The reader may also wish to refer to ASCE Standard 11- Guideline for Structural Condition Assessment of Existing Buildings . This standard may be a source of comprehensive information for clients such as building owners, prospective purchasers, tenants, regulatory offi cials, and others.
This standard is primarily directed toward a consultant-client relationship; modifi cations may be made to the content for condition assessments performed by staff personnel of public agencies and multibuilding owners for management of facilities.
This standard establishes an assessment procedure including investigation, testing methods, and a form for the report of the condition assessment. It assists the investigator in developing a logical approach to the assessment of the building envelope to focus on fundamental defects rather than outward symptoms. The possibility of encountering hazardous materials, such as lead-based paint and asbestos-containing materials, should be considered.
Because any evaluation involves "professional judgment" and contains factors that cannot be readily defi ned and standardized, a section providing guidance is also included. This section must be used by the design professional as part of the evaluation.
PURPOSE OF ASSESSMENT
Condition assessment of an existing building envelope may be undertaken for a number of purposes. These purposes may include developing a performance report, establishing building serviceability, planning for maintenance or repair, code compliance, life safety, durability, historic preservation, or a number of special purposes based on the specifi c building and its current or proposed occupancy or function.
