John Dahlmeier 612-472-4761 p. 3 John Horoshak August 27, 2001 OBSERVATIONS AND COMMENTS 1. Craig Oswell of J. H. Dahlmeier Engineering Inc. visited the site for an inspection of the framing on August 27, 2001. The following items were noticed in regards to the overhang framing: a. The overhang was framed with 2x4 studs spaced at 24" O.C. b. The stud overhang cantilevered three feet past the face of the wall. c. The studs were end nailed to the top chord of the truss nearest the wall. The truss was spaced two feet from the face of the wall. d. The studs extend over a truss, which was in line with the wall. The end truss's webs were framed in with 2x4's at 16" O.C. due to the gable condition. STRUCTURAL ANALYSIS 2. A structural engineering analysis determined the following: a. The current overhang framing is not adequate to support the code- required load. b. The current overhang framing will deflect approximately 0.58" at the overhang end under the code-required load. This value is approximately four times the recommended value for this type of condition. CORRECTIVE MEASURES 3. The following corrective measures are required for the overhang framing: a. A 1.75" wide x 3.5" high LVL should be placed on each side of each 2x4 overhang stud. The studs and LVLs should be nailed together at 12" O.C. b. The stud/LVLs should be attached to the truss top chord at their end, as well as to the truss at the wall, with a single Simpson H4 anchor. PROFESSIONAL OPINION 4. It is my professional engineering opinion that the overhang framing will be structurally adequate once the above corrective measures have been implemented. GENERAL 5. The observations and opinions expressed in this report were based on my professional engineering judgment and professional practice, as well as the visual inspection.
