<br />Consulting Services Agreement between City of San Leandro and Last revised 01/13/2025 <br />WPCP Structural Plan Review Exhibit A – Page 1 of 1 <br />EXHIBIT A <br />SCOPE OF SERVICES <br /> <br /> <br />LEAKING HYPO PAD <br />The former headworks station has a leaking hypo pad at the elevated ground floor slab that has caused <br />water intrusion, corrosion, and localized spalling at the slab soffit below. The existing floor framing <br />comprises a concrete slab spanning to concrete beams and girders. We will: <br />1. Review original drawings and photos of the damaged areas. <br />2. Provide initial repair options to you for review. <br />3. Develop sketches of the selected repair approach. <br />4. Provide a memo outlining our findings. The memo will include anticipated order of magnitude <br />pricing for the repair work. <br />The leaking will be repaired by others and the area with spalling is currently cordoned off. This proposal <br />does not include construction documents and calculations for permit, which we would be happy to provide <br />under an Additional Services agreement. <br /> <br /> <br />STEEL DIGESTER COVER MODIFICATIONS <br />We understand two new digester mixers are planned at the existing concrete digester tank. The work will <br />include a new access hatch and service box at each digester. During installation and servicing, the roughly <br />2,000 pound assembly at each mixer will vertically load the existing digester cover. The cover is <br />approximately 24 feet in diameter and appears to be constructed from radially oriented tube steel members. <br />A vendor has provided shop drawings for the mixers and service boxes, but has not designed connections <br />to the existing structure or assessed the existing structure under the added load. We will: <br />1. Document code requirements related to structural engineering calculations and drawings that will <br />be required for the proposed work. <br />2. Review the provided shop drawings and photos of the existing structure and identify any concerns <br />regarding connections to the existing structure. <br />3. Document required field measurements of the existing structure, if any. <br />4. Provide a memo outlining our findings and recommended next steps. <br />Our work will not include review of the shop drawing details aside from the overall approach and <br />connections to the existing structure. We will not perform calculations to verify the adequacy of any <br />structural members. <br /> <br /> <br />ADDITIONAL CONSULTATION <br />This proposal includes an additional phase to answer follow up questions and provide supplemental <br />structural consultation services for the Steel Digester Cover or other structural projects on a time and <br />materials basis. <br />Docusign Envelope ID: 19CAED29-6B12-42C2-A12A-EFB59AAE69B6
