The observation was completed on Wednesday, January 10th, 2024, in an effort to visually assess the condition of the existing facade along the East side of the property and the temporary stabilization support system constructed in 2015. This observation and report are only intended to identify discernable signs of distress, movement, and deterioration compared to our office’s last visual observation report dated November 12, 2020. OBSERVATIONS The North and South existing walls on each side of the property do not show evidence of movement since the previous observation. Both appear to be stable at this time. There is substantial plant growth and plant debris in the former basement area since the previous inspection, however the overall backfill slopes and drainage appear to be in similar condition to previous observations. The backfill slopes down to a center area covered with a tarp material to retain water. (See photos 1 and 2) The exposed faces of the North and South walls have been painted since the last site observation performed by Martin/Martin Wyoming. Both walls appeared to be in similar condition as previously observed. We have noted a crack at the base of the North wall located approximately 20 feet from the East elevation that appears from grade level up several courses into the masonry and grouted pocket above. We are unable to determine where the crack originated or when it may have formed. (See photo 3) The OSB sheathed walls of the stabilization system bracing the East façade appear to be in relatively poor condition due to prolonged exposure. Checking, delamination, and warping of various members of the floor was evident at the time of observation and continues to undergo corrosion. (See photos 4 and Several of the diagonal wood cross members at the roof level have either partially or fully detached from the horizontal girt and sheathed walls of the stabilization system since the previous inspection. This includes both cross members in the middle portion as well as one member in the south portion. The bracing of the ---PAGE BREAK--- 112 North 2nd Street East Façade Observation January 17, 2024 P a g e 2 I 7 East façade is considered compromised and no longer adequate based on our understanding of the initial design of the stabilization system. (See photos 4 and The wood header framing was missing at one of the window openings, thus exposing the interior brick header. This lack of support is considered a hazard which can result in the bricks detaching and falling over time. (See photo The wall sheathing of the two sheathing walls at the foundation level are showing increased signs of deterioration beneath the weather barrier at the base where they were not painted with the water-resistant paint (See photo The original design capacity of the walls is reduced by this deterioration and their capacity to adequately brace the walls is questionable. Previous visual building assessments by Pillar Engineering indicated slight bowing at the top of the wall deflecting towards the street. Increased movement or deflection of the wall was not evident at the time of this observation. The wall appeared stable at the time of the site visit. (See photo RECOMMENDATIONS As noted above and in previous reports to your office, the stabilization system for the east façade was provided as a temporary system and continues to undergo extensive decay and loss of integrity due to exposure beyond its intended use. Therefore, while stable at the time of the observation, continued use of the structure in its condition is a risk for failure and possible collapse if repair and/or a more suitable, permanent fix is not provided. It is not possible to quantify the capacity of the remaining structure due to its compromised condition. Therefore, we would like to reiterate the importance of either removing the remaining structure and stabilization system and/or replacing it with a more permanent system as soon as possible. LIMITATIONS Previous structural assessments and repair recommendations by Pillar Structural Engineering were provided prior to the observation. These documents and drawings were used by our office to acquire a comprehensive understanding of the existing structure, repairs, recommendations, and assessments. These documents were not analyzed by Martin/Martin Wyoming and, therefore, we do not take responsibility for the adequacy of the design, construction, or recommendations previously provided as they were not under the direct supervision of our office. Our investigation was limited solely to exterior observations of the property on 112 North 2nd Street and is based on conditions that were readily observable at the time of our site visit. Existing drawings were not provided for review and no invasive testing was performed. Neither the investigation nor this report is intended to cover mechanical, electrical, architectural, or other features beyond those described above. Martin/Martin Wyoming, Inc. does not accept responsibility for deficiencies not evident during an observation of this type. ---PAGE BREAK--- 112 North 2nd Street East Façade Observation January 17, 2024 P a g e 3 I 7 We appreciate this opportunity to be of service.
