BUILDING ENVELOPE COMPONENTS Sample Clauses
The 'Building Envelope Components' clause defines the materials and systems that make up the exterior shell of a building, such as walls, roofs, windows, and doors. It typically outlines the required performance standards for these components, including insulation, weatherproofing, and energy efficiency, and may specify acceptable materials or installation methods. By clearly identifying the scope and requirements for the building envelope, this clause ensures that the structure is protected from environmental elements and meets regulatory or design standards, thereby reducing the risk of future defects or inefficiencies.
BUILDING ENVELOPE COMPONENTS. A. A building envelope being proposed for a State of Michigan agency as tenant shall present a professional and permanent appearance, using durable materials in sound, weathertight, and code‐compliant condition. Design of the exterior envelope shall not rely on caulking and sealants for moisture exclusion.
1. Acceptable exterior wall materials include: Brick masonry and brick veneer Split‐face, glazed, or honed concrete masonry units. Painted concrete masonry is not acceptable except at the rear or non‐public elevations of the building. Insulated architectural metal panels Stone masonry and stone veneer Exterior insulating finish systems Redwood or cedar exterior wood siding and trim
2. Acceptable roofing materials include: Fiberglass or asphalt dimensional or 3‐tab self‐sealing shingles Built‐up or single‐ply membrane roof systems Metal roof panels
B. Concrete for new construction:
1. All foundation walls below grade shall be poured reinforced concrete or concrete block with reinforcing.
2. All concrete shall have a minimum compressive strength of 3,000 PSI in 28 days.
3. Concrete slabs on grade shall be four (4) inches thick with wire mesh reinforcing. Pour slab on four (4) inch sand bed, firmly tamped by mechanical means to insure a solid base with no voids or hollows.
C. Masonry for new construction:
1. Face Brick: grade “SW”, severe weather type, special shapes as required by building configuration.
2. Concrete Masonry Units: Hollow load‐bearing concrete masonry units, normal weight.
3. Masonry Accessories: horizontal and vertical joint reinforcement, ties, straps and weeps to meet design parameters.
D. Metals for new construction:
1. ASTM grade for structural steel shapes, plates and bars as determined to meet project conditions and design parameters.
2. Miscellaneous metals items shall use the best commercial quality for the purpose of items specified, free of defects impairing strength, durability, finish or appearance. Materials shall be formed truly and uniformly to required shape, size, sharp lines, and smooth surfaces.
3. Separate dissimilar materials with caulking, bituminous paint or gasket as approved.
4. Shop prime all exposed steel surfaces except where fire proofing is provided.
5. All steel decking must be galvanized or be provided with a rust prohibitive coating, shop applied.
