    WK25809

    1. Scope

    1.1 This guide provides information to assist in the specification, design, and performance testing of field-constructed exterior wall assemblies (mockups) for construction projects. This includes testing procedures appropriate to evaluate the component and assembly performance for water penetration resistance, air leakage resistance, and other test methods that may be applied as part of the quality assurance program for the installed systems. 1.2 This guide is intended be applied to exterior wall mockups that include components, systems, and assemblies including, but not limited to, curtain walls, windows, doors, masonry walls, precast concrete, cast-in-place concrete, exterior insulation and finish system (EIFS), roofing interfaces, stucco, wood siding, metal panels, sealants, appurtenances, penetrations, louvers, and combinations thereof. Such mockups are expected to include the intersection between wall systems. 1.3 This guide is not intended to provide a comprehensive list of potential testing that may be applicable to field-constructed mockups. Additional tests may be applicable to mockups of specific projects.

    Rationale

    4.1 This guide is intended to assist the construction team in evaluating the constructability, functionality, sequence of construction, interference, tolerances, component performance, and assembled system performance of the exterior wall systems. 4.2 This guide is not intended to establish specific roles for the parties involved during construction or the contractual obligations of those parties. The role of each party within any specific project should be established and documented before the start of the project. 4.3 This guide is intended for use when specifying construction mockups that are either integrated mockups or off-structure mockups. 4.4 This guide is intended to aid the specifier in the development of a quality assurance (QA) mockup program for assessing the performance of exterior walls. It is not intended to provide a comprehensive list of applicable test methods for QA testing available or applicable to a mockup program. 4.5 This guide does not address preconstruction laboratory testing of a wall system. 4.6 This guide is intended to address technical issues with the performance of the wall system and the interconnection of the various components and systems. A mockup may or may not be used as an aesthetic mockup; however, this guide is not intended to address aesthetic issues with the wall system. 4.7 This guide is not intended to provide guidance for construction observation services.

    The title and scope are in draft form and are under development within this ASTM Committee.
