DATE: September 24, 2026 TO: Annyse Acevedo, Procurement & Contract Compliance Manager Transbay Join Powers Authority Email: aacevedo@tjpa.org FROM: Parker Kjellin-Elder, Research Data Analyst II SUBJECT: Special Prevailing Wage Determination for Building Stationary Engineer Services Project Name: Building Stationary Engineer Services for Salesforce Transit Center County: San Francisco PAGES (Including Attachment): 12

MESSAGE

In response to a request received from the Transbay Joint Powers Authority on August 10, 2026, we have enclosed the Director's Special Prevailing Wage Determinations S-2026-31 and S-2026-32 for the aforementioned project within San Francisco County. Please note that these determinations apply only to the project for which they were requested. These determinations are being issued based upon the information provided which indicates that the contract for this project has not been let or signed. If the contract is not signed within twelve (12) months, please contact the Office of the Director - Research Unit for updated special determinations. Any extension or renewal of this contract will require the issuance of either new special prevailing wage determinations or the use of the general prevailing wage determinations in effect on the date the contract is extended or renewed.

As defined in Labor Code Section 1723, "Worker includes laborer, worker, or mechanic." Thus, the California prevailing wage determinations do not contain rates for supervisors, superintendents/managers and foremen. Prevailing wages are not required for them, unless they are actually performing covered work, such as a "working foreman." In such cases, they must be paid at the minimum, the journeyman rate for the type of work they are performing. Even though the supervisor rates are not published in the general prevailing wage determinations, the worker is not precluded from being paid a wage rate above the minimum journeyman's prevailing wage rate.

We have enclosed excerpts from the collective bargaining agreement, used as the basis for determination, relating to scope of work descriptions for the classifications of Stationary Engineer and Utility Engineer.

Please note that the attached scope of work provisions are advisory. These advisory scope of work descriptions are useful in assisting awarding bodies and other interested parties in complying with the requirement that the prevailing rate of per diem wages be paid to each craft, classification or type of worker.

We hope this addresses your concerns in this matter. If you have any further questions, please contact the Office of the Director – Research Unit at (415) 703-4774. You may also visit our website at http://www.dir.ca.gov/OPRL/DPreWageDetermination.htm to obtain current prevailing wage information.
