9 <br /> Chapel Hill Old Town Hall Structural Assessment <br /> Page 3 <br /> We recommend that deteriorated mortar joints be repointed by an experience mason. The <br /> cause of the water leaking must be identified and corrected to prevent further damage. Other <br /> locations may also require repointing, such as at a steel lintel where the mortar had become <br /> loose due to minor rusting of the steel. At that location, the lintel should be cleaned and <br /> protected before repointing. <br /> We also observed damage to the trim of the cupola caused by exposure to water. From within <br /> the cupola, the wood framing shows evidence of exposure to moisture, but we observed no <br /> significant structural damage. Once the moisture problems have been corrected, the trim can be <br /> replaced. <br /> Water damage to trim of cupola. Evidence of moisture at interior of cupola. <br /> Structural damage not yet significant. <br /> Below the lower portion of the cupola, some of the anchoring threaded rods were visibly loose. <br /> We recommend that these be tightened: <br /> i <br /> P <br /> View of loose threaded rod inside the cupola. <br /> In summary, it is our opinion that the overall structural condition of the building is very good. <br /> Other than the items noted above associated with moisture, we observed no visible evidence of <br /> distress to the structure. <br /> ,`1 LHC STRUCTURAL ENGINEERS <br />
