A thorough review and commentary of each enclosure-related technical specification section covering provisions and requirements is provided and intended to improve the performance and implementation of the prescribed work. The consultant also reviews technical specifications and the testing and inspection procedures for each major building enclosure system.Ĭonstruction Documents (CD) phase.During CD, reviews of drawings and technical specifications help the team to further refine the integration of interface detailing and the selected enclosure systems. Mark-ups and written comments on the development drawings include specific recommendations and design detail concepts, such as refinement of flashing and system integration details. The consultant helps the project team to work through the design concepts, providing detail sketches for the team to consider incorporating into design drawings.ĭesign Development (DD) phase.During DD, the project team typically uses the consultant’s input to compare interface detail options. These include the materials and interface details for below-grade, fenestration, facade cladding, and roofing systems. During SD, the consultant typically focuses on the major build-ing enclosure systems and materials, offering the project team recommendations about the systems and manufacturers under consideration for the building enclosure. Assist in resolving field condition issues during construction.Assist with required functional performance testing for envelope systems and mock-ups. Minimize construction delays due to unanticipated issues.Provide support for construction coordination of envelope trades.Synchronize project design and construction phase documents.Ensure unified and continuous integration of building enclosure systems.Propose the most appropriate selection of materials.Avoid design problems prior to construction.Achieving Key Objectives for New ConstructionĪs a member of a project team for new construction, a building enclosure consultant offers engineering insights and services that help the team achieve a number of important objectives: Practically, the building enclosure consists of the components of the exterior “envelope” or “skin”: foundations, slabs, basements, plaza decks, balconies, wall systems, storefronts, curtain walls, doors, windows, and roofs. Technically, the building enclosure consists of the sum of the physical barriers between the exterior and interior environments or, more precisely, between the unconditioned outside atmosphere and the conditioned and controlled indoor space. Depending on the type of project, building enclosure consulting services may benefit the architect, contractor, property owner/manager, developer, and insurance company, or construction law firm. At the very least, these problems may result in occupant discomfort and tenant dissatisfaction at their worst, they may raise liability risks for the owner.Ī building enclosure consultant contributes specialized engineering knowledge for the effective integration and continuity of air, water, and thermal barriers for below and above-grade structures, including exterior cladding systems, fenestration, and roofing systems. The issues that result from inadequate integration and continuity of water, air, and thermal barriers also increase ongoing operational, maintenance, and repair costs. Water penetration in the form of moisture-laden air or bulk water is one of the biggest problems - surprisingly, almost every building leaks at some point during its service life - often resulting in costly damage to interior building materials. Many new and existing buildings do not perform as anticipated due to problems with the design or construction of the building envelope.Īir infiltration and exfiltration, along with unmitigated heat transfer, can lead to poor energy performance and other adverse issues.
