The annular seal is leaking gases and moisture. If the moisture is not stopped the contractor Southern Minnesota Urethanes, LLC with BASF the spray polyurethane foam (SPF) company will not back the Non -prorated system ten (10) year warrantee for spray polyurethane foam (SPF), top coatings and labor from roof insulation failure. The moisture from the annular seal will cause the primer to fail and then rusting will accrue on the digester metal roof causing the SPF not to adhere. The contract bid for this project is $42,000.00 for removing all old roof digester SPF, preparing a clean digester metal roof surface, primer the metal roof surface, the SPF, and sealing or coating the SPF surface. Change Order #1 will seal the annular seal area, creating a vapor barrier so moisture will not get under the SPF. The contractor will remove some of the sand in the annular seal area, as it is wet; clean/prepare the side surfaces in the annular space, concrete on one side and metal on the other side of the annular space; add dry sand if needed; install backer rod; then pour MasterSeal SL2 a Multi-component self -leveling polyurethane sealant to top/even with concrete wall. Contract estimate was $65,000.00. Change Order #1 at a cost of $16,000.00. Total cost for the project is $42,000.00 + $16,000.00 = $58,000.00 Recommend City Council approval of Change Order #1 to receive a long lasting roof product, to complete the project in a timely manner and to receive the Non -prorated system ten (10) year warrantee for spray polyurethane foam (SPF), top coatings and labor.
