Subject: Structural Framing 520 NorthShef%a ommon Building
To Whom it concerns:
I visited the job site to review framing for the Common Building on Monday March 15, 1999. The follow are my
comments:
1. Bracing needs to be added to exposed roof trusses in horizontal plane. This bracing should be placed
approximately 10'-0 above finish floor level and may be 4" X 4" or large rough sawn members to match
existing exposed trusses. Attachment is shown on enclosed sketch #1.
2. Truss bottom chord members should be attached to wall framing studs. 2 ''/z" diameter lag bolts are
required at each end at all interior trusses. Refer to sketch #2 enclosed.
3. Add 2" x 6" diagonal bracing to west exterior wall. Refer to sketch #3 enclosed.
4. One bolt is missing in first interior truss. One sided connection is acceptable where existing mortise
occurs in web member.
5. Steel beam to steel column should be field welded. A 3/16" fillet weld minimum 2" long each end is
required:
6. Simpson strap material with a minimum length of 4'-0 should be added to exterior of building where
top wall plates have been interrupted.
7. Add solid blocking in framed walls to foundation sill plates below all concentrated loads.
8. Dry pack steel beam to wall beam pocket and add connection angle per Sketch 44 enclosed.
9. Recycled wood members used in exposed trusses are adequate for loading expected.
