The firm has a continuing <br />contract with Public Works Department for professional geotechnical engineering and construction <br />testing/inspection services. Specific services are listed on the attached Work Order. <br />The lump sum professional services fee associated with Work Order No. AACE-1 is $80,505.00. <br />FUNDING <br />Funding is available from Optional Sales Tax/Public Works/CIP-Moorhen Marsh -PC North, Acct <br />#31524338-066510-16018. <br />Funding Source Amount <br />Optional Sales Tax/Public Works/CIP-Moorhen Marsh -PC North, Acct <br />#31524338-066510-16018 <br />$80,505.00 <br />RECOMMENDATION <br />Staff recommends the Board of County Commissioners approve Work Order No. AACE-1 in the amount <br />of $80,505.00, and authorize the Chairman to execute it on behalf of the County. <br />ATTACHMENTS <br />Work Order No. AACE-1 <br />Exhibit A — Andersen Andre <br />APPROVED AGENDA ITEM FOR April 20, 2021 <br />56 <br />
