DIBBLE ENGINEERS INC <br /> June 15, 2016 <br /> Mr. Brian Bodge <br /> 3015 Everett Avenue <br /> Everett,WA 982.01 <br /> Re: Bargreen Property Sign Pole <br /> Dei Project#: 16-224 <br /> Dear Mr. Bodge: <br /> Dibble Engineers Inc.(DEI) has complete a structural review of the proposed commercial sign pole and footing for <br /> installation at the address given above. Per the drawings provided Mr. Bodge dated 4/26/2016, the pole will consist of <br /> a 12ft tall HSS8x8x1/4 pole with a 13ft tall Pipe 5"Standard pole fastened on top. The upper pipe section of the pole <br /> will support a 10'-0"wide x 5'-0"tall sign and two 6'-0"wide x 4'-0"tall signs face mounted to the pole per the:sign <br /> manufacturer. The pole will be anchored to a pre-cast 2'-6"diameter x 8'-0"deep concrete footing with 4000psi <br /> compressive strength.The pole will be anchored with four 1"diameter cast-in-place anchor bolts with 31"of <br /> embedment. <br /> Based on our analysis,we have found both the sign pole and the proposed footing and anchorage to be structurally <br /> adequate to resist code prescribed wind forces. DEI recommends fastening the pipe section of the pole to the HSS <br /> section by inserting the pole a minimum of 8"into the HSS and welding them together with four 1/4"A'x8" <br /> perpendicular connector plates. Please reference the attached sketch SK-1 for additional information. DEI also <br /> recommends that the pole base plate be a 1-%"x14"x14"ASTM A36, Fy=361<si plate. Please see the attached <br /> sketch SK-2 for further clarification. <br /> Dibble Engineers' review is limited to the sign pole,footing, and anchorage. Unless specifically discussed in our <br /> review, no other conditions were evaluated or considered. Our review and discussion summary does not provide <br /> warranty either expressed or implied to the existing conditions. <br /> Dibble Engineers appreciates your business.We invite you to please contact us with any questions or for <br /> clarifications to our work, and we will be happy to assist. <br /> Sincerely, <br /> DIBBLE ENGINEERS, INC.
