Show sanpete Development Corporation -2- June 5, 1969 force reactions to the four building walls. This membrane can be readily achieved with nothing more than 1/4" thick plywood or particle board nailed o ~ to existing sheathing in 4' x 8' sheets with barbed or cement-coated nails. (e) The existing ceiling at the roof soffit line is to be totally removed to expose the present roof trusses to view from the second floor as suggested by Mr. Purcell except for such portions of the ceiling as you wish to retain at the east end for access from the existing stairway to the top of the present grain elevator. (f) The second floor jOists and flooring, when cleaned up, will probably be found to be in good condition, based upon our under-floor inspection, but their supporting girders and posts will require some rearrangement. Subject to further analysis based upon actual dimensions of the existing floor jOists and flooring , one or two lines of supporting girders can be used in the east-west direction, as you may elect, to support the floor. (g) Maximum spacing of posts in an east-west direction under these girders is limited only by the size of girders selected~ thus, you may have virtually any arrangement you wish to fit the intended use of the ground floor. (h) No stabilization of existing foundations appears to be necessary at this time. The diagonal tension (shear) cracks in the west front wall apparently occurred during the earlier pci.'rt' , of the structure life, as the same cracks show up in one of your early day photographs. The tension members proposed under paragraph (a) above will be deSigned to prevent further movement. R::<,::..:" -;-' ~ '. ,~; ,:'\\ 2. The present grain mill buil di ng south of the Relief Society building is also capable of structural rehabilitation at relatively minor cost providing the present storage bins and distribution chutes-are~ert--i easonably intact to support the roof trusses in their present geometry. Essential items of work as now determined, but subject to further inspection, are as follows: (i) A rigid membrane is needed over the entire. roof surface for the same reasons given in paragraph (d) above. However, in absence of any existing roof sheathing, plywood sheets, 5-ply, 1/2 II in thickness \-lill be needed if roof purlin spacing does not exceed 24 inches. (j) Roof purlin strength must be checked from actual dimensions and inspection of connections. When completed, a positive connecti on must exist between the roof and walls as noted under paragraph (b) above. (k) The original roof trusses, as \~ discovered during our inspection, have been substantially altered and raised in elevation to accomodate storage bins and distribution chutes. The |
