81 5th St - Engineering Letter OFFICE COPY LJG Engineering, Inc. Principal Engineer: Louis Gabriel PE 419 Sophia Terrace Saint Augustine, Fl . 32095 5/ 12 / 2016 Subject: Structural revisions to 81 5th St. Atlantic Beach, Fl. Permit#: 15- RADD-2763 Dear Building Inspector:- After the demolition work was completed at the above referenced address, The following revisions to the original scope of work is approved by me:- 1- The homeowner has decided to keep the existing post between the garage doors which now supports (2) 2x10 beams spanning to the post located in the middle of the garage. As a result: - the (2) 1 3/4 x 14" LVL shown on sheet S-2 will not be necessary - the (3) 8" W x 12" H concrete curb reinforcements shown on Sheet S-1 will not be necessary. The 2' awning covering the garage extension will be supported by 4x4 PT posts which will be anchored to the existing concrete driveway. 2- Few of the existing 2x8 floor joists spanning from the garage to the support beam were replaced, at the time of the original construction by 2x10 and 2x12 joists, which were notched at their bearing points (the original builder probably ran out of 2x8 lumber and decided to use what he had left on site: i.e the 2x10 and 2x12). As a result the distance from the bottom of those 2x10 and 2x12 joists to the top of the 24"x 24"x 10" concrete pads is different from that of the 2x8 joists. It was determined that the 8"x16" CMU added over the concrete pads to reach the bottom of the new (3) 2x12 PT beams, which will carry the weight of the bearing wall, can be replaced by 6x6 PT posts, cut to size to fill the gap, and anchored to the concrete pads with ABU 66 anchored with 5/8 7" wedge anchors. The 6x6 PT posts will be strapped to the (3) 2x12 beam. 3- Roo . - - - . oom: the 2x10 joists added to the existing rafters on p- . ,••••,cyciaar. essary.

The (3) 2x12 PT supporting the weight of the balcony will span the 9'3" between the first post located on the right side of the steps and the post located on top of the south end of the 20" W x 12" D concrete beam Sincerely, nuuw t1 %,, 4.1G:::..444.1 F ..
