Date: 09/26/12 1650 Fallridge Road,Unit C2 ' Vail,Colorado 81657 Project: Vail Fire Station Location: Vail,Colorado Contractor: G.E.Johnson Owner: Town of Vail Weather: Partly Cloudy, 50 deg Present at Site: John King Alian Arnason Tim Boyle Bill Pierce Fritzlen Pierce Architects 1650 Fallridge Road,Suite C1 Vail, Colorado 81657 Field Report The following items were observed: I met with John King and Alan Arnason on site to review a couple of specific existing conditions. This is a summary of our conclusions. We first reviewed the existing floor and roof framing west of the existing CMU wall where the new stair tower will be constructed I instructed Alan to construct the new CMU tower wall to the height shown on the plans,and then to frame a 2x6 @ 16" o.c. cripple wall on top of it up the the underside of the existing upper floor joists. The top of this wall wall have a double 2x6 tap plate, The portion of the existing joists that eatends past the east side of the new wall will then be cut off flush with the new framing. The existing CML7 wall that supports the roof rafters in this area has existing bond beams, but most of the vertical cells appear to be hollow. This wall is to be grouted solid, and 1 #4 vertieal reinforcing bar is to be installed @ 16" o.c. into every second cell. The rafters west of this wall currently hang off of an existing ledger. Once this wall is repaired, Alan will verify the distance between the end of the rafters and the face of the CMU wall. We will then coordinate the ledger size and connection of the new iedger to the CML7 wall. The exrsting rafters will be hung from the new ledger. The last area that we reviewed was the 14' ta112x4 central bearing wall in the building that supports the east end of the rafters for the west roof. These studs are excessively tall for their size, and many of them have been notched for plumbing lines. This wall is quite deficient in its current state. I concluded that each of the existing studs should be "sistered"with a new 2x6 stud. These should be nailed to the existing studs with 8d nails @ 12" o.c. The existing 2x4 top plates will remain, but a ripped 2x4 should be installed adjacent to the existing sill plate to provide full bearing at the bottom of the new studs. This sill plate extension should be glued to the floor decking with PL400 and nailed with 8d @ 16" o.c. A portion of this wall toward the north end will essentially be reframed completely as a 2x6 @ 16" o.c. wall in the area where there are existing headers for openings that have since been abandoned in order to eliminate the hinge point midway up the wall. Finally "X"'s of Simpson WB wall bracing should be installed along one side of this wall to provide additional lateral stif�ness. This completes the items covered during this meeting.
