As mentioned in the last correspondence, the retention ponds must be cleaned of all <br />excess concrete, fine silty material and debris as a final step. <br /> <br />19. Buried rubble near the block walls should be removed. <br /> <br />Again, as I mentioned in our last letrer, we recognize that you have not retained us to provide <br />frequent observation services at your site, and we have not invoiced you, as yet, for our time. <br />We have simply noted these things while driving by or during informal visits. We mention <br />them to you strictly out of concern for your investment. However, we feel you need some <br />independent oversight at the job-site to better ensure the quality of work. We would <br />recommend laboratory testing on all future concrete work and would recommend excavating <br />and backfilling the future pavement areas a second time so that you can ensure that the material <br />, will be brought to grade in sequential, compacted l~. We would recommend that each lift be <br />tested to ensure that it attains at least 98 % of the maximum dry density of the material in <br />accordance with the modified proctor. <br /> <br />Finally, we recommend that the structural engineer of record for this project be called in to <br />inspect work completed to date to evaluate its structural integrity and make recommendations <br />for additional retrofit work, if necessary, to ensure the structure's stability. <br /> <br />We bring these things to your attention for your protection and for the ,protection of your end <br />product. Undoubtedly, you have invested significant time and resources in this project, and we <br />want the final product to be successful. Please call us should you have any questions regarding <br />any of the items in this letter. ' <br /> <br />~, <br /> <br />Edwin J.
