The <br />report that follows has been prepared based on that inspection. This inspection was performed by Paul <br />Schimnowski, PE. <br /> <br />My work includes the following: <br />1. Visual observations during a site visit on April 20, 2022. <br />2. Observe factors influencing the performance of the structure. <br />3. Provide a written report containing the following: <br />a. Scope of services. <br />b. Observations, site characteristics, and data deemed pertinent by me. <br />c. Discussion of structural factors influencing the performance of this wall. <br />d. Conclusions and any recommendations for further investigation and remedial or <br />preventative measures. <br />e. You asked me to pay special attention to the forward movement of the wall, horizontal <br />gaps in the face of the wall, deteriorated block at the top of the wall, and erosion at the <br />base of the wall <br /> <br />SUMMARY <br /> <br />In my professional opinion, the overall structural condition of this concrete masonry unit (CMU) retaining <br />wall is considered to be poor when compared to others of similar age and construction type. The wall is <br />failing and is reaching the end of its expected useful life. Due to its deteriorated condition, options for <br />repairs to re-establish structural stability of the wall are limited and may not be cost-effective in extending <br />the life of the wall. Replacement should be anticipated in the next few years. <br /> <br />SPECIFIC ITEMS NOTED & ASSOCIATED RECOMMENDATIONS: <br />1. The top of the wall is displaced outward by about 2 to 3 inches near the center and north <br />sections of the wall. <br />2. Horizontal gaps have developed at the wall face due to wall displacement and settlement. <br />3. Some of the cap units, block, and mortar are deteriorated due to freeze-thaw damage. <br />4. The cores of some of the blocks are exposed. This will allow water to infiltrate and further <br />deteriorate the block. <br />5. Structurally significant erosion has occurred at the base of the wall which has exposed the <br />footing. For a wall of this type, the bottom of the footing should be at least 42-inches below
