While not conforming to code the suitability of the slab for this purpose is judged based on its past performance (over 20 years old), thickness and quality (approx. 10" and no apparent defects/cracks), and good drainage and soil characteristics. We will be using 5 columns to support the main beam. Your existing s.l.ab_.is_structurall�r ad_e_ uate to accept the proposed loading of the columns. I will say that if you do this then you are accepting the responsibility that there may be differential movement due to the presence of different foundation systems and a lack of frost protection on the siab. - Extend the stair bump out to at least 60 inches from the ledger board. This would allow for the use of a 6x6 column with a concrete footing, the edge of which would just clear the sidewalk. I measured and actually 62" would be ideal, leaving a 2" gap between the footing edge and sidewalk. This is acceptable. - While I will probably use the Simpson A35 angles (I have not ordered them yet), if there is a problem with obtaining these I would like the option 8/8/2011 Page 2 of 2 of using an equivalent product. Any USP equivalent is acceptabfe. - The option to substitute Simpson LUS28 face mount hangers, or equivalent, for LUS26 face mount hangars. Anything above and beyond the LUS26 is acceptab{e. Thanks for your insights on the stair thread issues. I was able to get the ESR for the decking material I'll be using and found it to be rated at 300 Ibf., with a maximum center to center spacing of 12". This will satisfy the code requirements and the product should ho�d up much better than wood over time. On your comments, please reference Fridley permit # 2011-01275 and copy Ron 7ulkowski at �ulkowskir�ci,fridle�r._mn.us . Thanks so much! Frank Sedzielarz 1318 Hillcrest Dr., Fridley MN 763-572-9765 PS- We have not started on this project yet as Menard's delivered the materials late (>2 weel�s) at which my neighbor who's helping me on this left for vacation in Germany. He'll be back in a week and we'll get started. � 8/8/2011
