Scope of Services

General

A. Overview

The Construction Manager (CM), Resident Engineer (RE), and Construction Inspector (CI) are Central San representatives serving as advisors and consultants on construction matters related to the work. Activities during construction will be approached as a team effort, with Central San or its representative leading overall.

All instructions to the Contractor and all communications from the Contractor to Central San or the Design Engineer are routed through the CM. The CM is expected to make initial decisions on questions that may arise regarding the quality or acceptability of materials furnished and work performed, and the manner of performance and rate of progress of the work. The CM is also expected to interpret the Contract's intent and meaning and make initial decisions regarding the Contractor's performance under the Contract and the Contractor's entitlement to compensation.

Depending on the expertise of the selected Proposer, Central San reserves the right to implement a different arrangement of assignments and responsibilities between Central San staff and the Proposer. Whenever Central San determines that it would be in the best interests of the individual project, Central San reserves the right to: 1) use qualified Central San staff or other consultants to provide construction management services; 2) direct the Consultant to integrate qualified Central San staff into their team; or 3) add or subtract scope during contract negotiations and the duration of the contract.

Proposer shall ensure that any AI tool used does not store, reuse, or train on Central San data in a manner that could disclose such information to third parties.

E. Verification and Disclosure of AI-Assisted Work. Any Deliverable, analysis, report, model, or other work product that is materially generated or materially assisted by an AI tool must be reviewed, verified, and approved by qualified Proposer personnel prior to submission. Verification must include confirmation of engineering assumptions, calculations, methodologies, and compliance with applicable codes and standards. Proposer shall identify AI-assisted content upon request by Central San. Use of AI for clerical functions (e.g., formatting, grammar) need not be disclosed.

F. Restrictions on Autonomous or Safety-Critical Decision-Making. AI tools shall not autonomously generate or recommend engineering decisions that could affect public health, safety, or welfare. AI tools shall not be used to autonomously perform or direct any activity requiring professional licensure or technical judgment.

G. Intellectual Property Compliance. Proposer shall ensure that any AI-generated or AI-assisted content does not infringe upon the intellectual property rights of any third party. Proposer shall indemnify, defend, and hold harmless Central San from any claims arising out of such infringement.

H. Central San’s Right to Review and Restrict AI Use. Upon request, Proposer shall provide a description of any AI tools used in connection with the Services, including the purpose of use, data inputs, and verification procedures. Central San may prohibit or limit the use of any AI tool it determines poses unacceptable risk.

I. No Additional Compensation. Use of AI tools shall not entitle Proposer to additional compensation, time extensions, or relief of any kind.
