The original anchorage of the brick veneer was reviewed by MWA architects. In reviewing that submittal, I noted that spacing to be constructed was not noted. The spacing required was given in the Project Specifications (Section 04200 -3.6.3 and 3.6.4;. In reviewing the specifications, I noted an error in that they didn't conform to current IBC and IBC reference codes. Attached is the anchorage product, corrected spacing required for the HB Latter Eye-Wire anchors selected, and Contractor's acknowledgement to use the revised spacing. This letter should be considered the deferred engineering submittal for anchoring the brick veneer for the Building Department. The proposed structural anchorages for brick veneer are now in conformance with the project structural design criteria, plans, and revised specifications. Please call me if you have any questions. a■ p�. ! i ® Pfi Sincerely, 1 k� .6r .: L , 10,06 Gary '•.yor, PE, SE V r- GER:dsm Sr Project Engineer . 1 q(`• 23 �q' '9�E.

Stopping and Resuming Work: Stop work by racking back units in each course from those in course below; do not tooth. When resuming work, clean masonry surfaces that are to receive mortar, remove loose masonry units and mortar, and wet brick if required before laying fresh masonry. D. Built-in Work: As construction progresses, build in items specified in this and other Sections. Fill in solidly with masonry around built-in items. E. Fill space between steel frames and masonry solidly with mortar unless otherwise indicated. .3.5 MORTAR BEDDING AND JOINTING A. Lay hollow brick as follows: 1. With face shells fully bedded in mortar and with head joints of depth equal to bed joints. 2. With entire units, including areas under cells, fully bedded in mortar at starting course on footings. B. Lay solid masonry units with completely filled bed and head joints; butter ends with sufficient mortar to fill head joints and shove into place. Do not deeply furrow bed joints or slush head joints. C. Tool exposed joints slightly concave when thumbprint hard, using a jointer larger than joint thickness unless otherwise indicated. 3.6 ANCHORING MASONRY VENEERS A. Anchor masonry veneers to wall framing with seismic masonry-veneer anchors to comply with the following requirements:. 1. Embed tie sections in masonry joints. Provide not less than 1 'A" inches of air space between back of masonry veneer and face of sheathing. 2. Locate anchor sections to allow maximum vertical differential movement of ties up and down. 3.
