Box 4572 Vail, Colorado 81 B59 970-949-9991 FAX 949-1577 TO: Blu Sky Restoration ATTENTION: Chris Kintner PROJECT: 226 Cnty Rd 126 Deck FIELD REPORT DATE: 03/22/11 ARRIVE: 7:45am DEPART: 8:15am WEATHER: cldy/cool JOB NUMBER: 1103-09 PRESENT AT SITE: Chris, Homeowner STATUS OF COMPLETION: N/A On March 22, 2011 I visited the above -referenced site to observe the damaged deck joists (north deck) reportedly caused by sliding snow from the roof above. I was told that the original house and deck(s) were built in the 1980's and that an addition had been constructed in 2002. However, no construction drawings were observed during the site visit. I observed the framing for the north deck, and specifically, the damaged joists, which were located where there is a jog in the deck framing (I'm told that this was where the new deck was added in 2002). The deck framing consists of 2x8 joists spaced at 16 inches on center. These joists hang off of a 2x ledger at the house structure, but appear to be end - nailed to a single 2x8 rim at the edge of the deck. Four log columns appear to precariously support the deck framing, although no actual beam is bearing on these columns. Blocking was installed between two joists to provide some general bearing at these columns, but again, no actual beam supports were constructed. There were four damaged 2x8 joists adjacent to the jog in the deck framing that were moderately to severely cracked from the impact of the sliding snow. The rim beam that supports these joists appeared to have also shifted lower where it attaches to the newer deck. The deck beam supporting this rim beam also appears to have become partially dislodged on one end, near the concrete pier. ,�Yy Each of the four damaged deck joists shall be reinforced/replaced with a 1 3/< x 7 1/4 LVL (16 inch maximum spacing). Hangars shall be installed on each end of these joists as shown on the attached plan view. The 2x rim supporting these joists shall be reinforced with an additional (2)-2x8's for a total of (3)-2x8's. The adjacent beam shall also be reinforced with an additional (2)-2x8's, and this beam shall be anchored to the concrete pier and the log column per attached plan. In addition to the damaged area mentioned above, the remaining deck structure observed does not meet current design load standards as constructed. A beam should be added over each of the log columns, the rim beams should be reinforced, and hangars should be added to each joist as shown on the attached plan view. Please do not hesitate to call with any questions or to discuss this report further. KRM Consultants, Inc. SIGNED: Tim D.
