Attachment 5 CMU Column Wrap Detail.pdf

This is a technical construction detail drawing depicting a wall section assembly at the interface between exterior and interior surfaces. The drawing illustrates the construction of a concrete masonry unit (CMU) block wall with an embedded cavity detail that accommodates an existing structural element passing through the wall system.

The key construction components specified include: CMU blocks forming the primary wall structure, grout-filled cells with reinforcing as required, a 3/16-inch diameter wire anchor for structural tie-down, an existing concrete slab at the top, backer rod and sealant applied on both sides of the opening, and light-gauge metal backer material as needed. The detail shows the exterior face at the top and interior face at the bottom, with the opening accommodating passage of the existing structure while maintaining seal integrity and structural continuity through the use of anchoring devices and sealant materials. This appears to be a construction specification drawing for a renovation or retrofit project rather than a federal contract solicitation document.
