Consulting Services Agreement between City of San Leandro and Last revised 2/14/2024 V&A CONSULTING ENGINEERS for CONCRETE STRUCTURES CONDITION ASSESSMENT Exhibit A – Page 1 of 3 EXHIBIT A SCOPE OF SERVICES Task | Description 1. Project Management: Track and execute the project in accordance with the schedule, budget, and quality expectations that are established. The project duration is assumed to be 3 months. This task includes the following project management work activities: a. Monitor project progress, including work completed, work remaining, budget expended, schedule, estimated cost of work remaining, and estimated cost at completion; manage activities within the total project budget. b. Monitor project activities for potential changes and anticipate changes whenever possible; with approval, modify project tasks, task budgets, and approach to keep the overall project within budget and on schedule. c. Manage the quality of all work activities and project deliverables. 2. Document Review and Preparations: Review the drawings and existing documentation for the structures to prepare for the assessment. Prepare the testing equipment necessary to perform the assessment. For the confined space entry assessment of Digester 4, V&A will follow Cal OSHA protocols in the field and will prepare a confined space entry permit; however, a safety plan will not be submitted. 3. Visual Assessment: Perform a high-level visual assessment of the structures. A total of 12 structures will be evaluated during a one (1) day site visit, assuming that the structures will be available during the site visit. Confined space entry will not be performed. The assessment will be performed by two V&A personnel. The assessment will include the following: a. Visual Assessment: Qualitative condition assessment observations are subjective and based upon the evaluator’s expertise. i. Visually assess safely accessible surfaces of the structures. ii. Rate conditions using the VANDA® Concrete Index. See attached. iii. Document observations using digital photographs. A minimum of 10 photos will be obtained from each structure. 4. Detailed Assessment: Perform follow-up detailed assessments of concrete conditions based on the results of the visual assessment performed in Task 3. V&A will provide a list of structures to be assessed in detail. Provide two (2) V&A engineers and testing equipment for one (1) day to collect detailed information that will help characterize the extent of concrete degradation, as accessible , without performing confined space entry. Provide four (4) V&A engineers and technicians to perform a detailed confined space entry assessment of Digester 4. The following methods will be performed, as applicable, on a structure-by-structure basis. i. Measure the thickness of concrete protecting the reinforcing steel using surface penetrating radar (SPR) at up to 4 easily accessible locations in each structure to be assessed. ii. Assess the concrete condition by “sounding” accessible surfaces to listen for shallow DocuSign Envelope ID: B1FEB12C-3187-4688-9A64-AA6A32699F6E
