Question: Determine the number of specialty blocks needed, additional rebar required, and number of standard blocks that can be deducted when building a wall with the opening shown in Figure 6-4. The wall is constructed of 7 5/8-inch-high by 7 5/8-inch-wide by 15 5/8-inch-long blocks with a 3/8-inch mortar joint. The blocks at the top and bottom of the opening are to be the lintel block shown in Figure 6-3, with the blocks at the bottom placed upside down to provide a smooth surface. Bullnose blocks are to be provided at the sides of the opening. A 2 × 8 wood frame with a center support will be provided to support the bond beam until the grout has cured.
