27 Single Wythe CMU vs Precast Versatility Architectural effects (limitless) Variety of unit sizes, shapes, textures, finishes, and colors Banding and integrated patterns Pigmented mortar Curb appeal (making a statement)

28 Single Wythe CMU vs Precast LEED Masonry manufactured locally support Michigan

29 Single Wythe CMU vs Precast Structural Panel weight on foundation New system design software RAM Elements NCMA SMDS Direct Design 3DiQ BIM interfacing

30 Single Wythe CMU vs Precast Structural Masonry bearing pockets (less eccentricity) vs. Precast loadbearing connection (greater eccentricity) Masonry wall can be designed as a pinned or fixed base Internal wall bracing (fixed base) Precast panel typically designed as a pinned base Masonry wall can be designed as partially reinforced and insulated

31 Single Wythe CMU vs Precast Initial Construction Cost Comparison Caulking of precast concrete panel joints (interior and exterior)

32 Single Wythe CMU vs Precast Construction Masonry productivity Electrical conduits easier to account for in lieu of casting in precast concrete Interior joints struck flush behind insulation No cell fill Moisture management (IWR) Flashing Tolerances for masonry wall vs. precast concrete panel

33 Single Wythe CMU vs Precast Flexibility of Masonry Last minute design changes and corrections are easier Variation in footing elevation Openings

34 Single Wythe CMU vs Precast Schedule Precast concrete panel lead time Time required for the temporary shoring of the joists and girders Speed of construction

35 Single Wythe CMU vs Precast Maintenance Cost Caulking of precast concrete panel joints time consuming and prone to failure due to panel movement, especially at the corners Painting precast concrete panels Staining precast concrete panels Pigmented masonry requires no exterior/interior painting or wallpaper
