ENG PRESIDENT PROJECT: SEA BRINNON 124 EAST GO ONNA DRIVE QUILCENE, WA 98376 SUBJECT: POST MODIFICATION LETTER At your request Adapt Inc (Adapt) has reviewed the mount analysis, dated March 1, 2021, and photos of the modified antenna mount for the site referenced above to determine if the mount modification has been performed in accordance with the upgrades recommended in the mount analysis. Listed below is a summary of our findings: •After reviewing photographs of the antenna mount (dated October 12, 2021), it is our opinion that the antenna mount modification has been completed in accordance with the March 1, 2021 mount analysis. The contents of this post modification inspection letter are based on information obtained from KMM Corporation and their agents. Our review is based on the assumption that the existing structure was properly designed and constructed, and the antenna mount was replaced according to our mount analysis and components were installed per manufacturer’s specifications. Since we have not visited the site, Adapt makes no claim regarding the current condition of the structure. If defects (e.g. damage, corrosion, etc.) are noted at the existing antenna mount or its connections to the existing steel monopole, Adapt should be contacted so that appropriate retrofit options can be discussed regarding this project. We appreciate the opportunity to be of service to you. If you have any questions, or if we can be of further assistance to you, please contact us at (206) 654-7045.
