These requirements apply to Vendors and Contractors who provide services on the Princeton University campus and/or in University-owned or leased buildings (“University Property”). 

These requirements do not apply to long term temporary agency staff, who must follow all University policies when working under the direction of a University employee or faculty member.

All University Contractors and Vendors who provide services on campus or in University Property must comply with New Jersey Department of Health public health guidance, , and any additional requirements and instructions provided by the University representative with oversight responsibility over their engagement (the “University Representative”).

Contractors and Vendors must also comply with the following University requirements:

  • Effective August 11, 2021, all individuals in buildings occupied by the University must wear a face covering, regardless of vaccination status. Exceptions to this requirement include working alone in a room or cubicle or when actively eating or drinking. Face coverings are not required outdoors. 
  • The Contractor/Vendor must each day document names of all employees, workers, visitors, third parties, and all other individuals present on the University work site for whom the Contractor/Vendor is responsible.  The work site must be maintained to prohibit the entrance of any persons, including students, employees, workers and visitors who do not sign in. 
  • The Contractor/Vendor must obtain University approval from the University Representative to use shared spaces outside of the work site.  These shared spaces include areas outside the project/work limits occupied by both the public and Contractor/Vendor workers.  This approval may require that the Contractor/Vendor be responsible for cleaning/sanitization of such shared spaces.
  • Contractors and Vendors who provide services on University Property must notify, within 24 hours, Environmental Health and Safety ( sends e-mail)) if an employee, worker, visitor, third party, or any other individual for whom the Contractor/Vendor is responsible and who was at the work site:

    • Providing the affected individual’s name and contact information to Environmental Health and Safety ( sends e-mail)), who will conduct contact tracing to identify University staff, faculty or students who may have been in close contact with the affected individual.
    • Closing the work site until completion of cleaning and disinfecting all surfaces within the renovation/construction spaces that may have been touched by the individual, including break areas, elevators, stairwells, and restrooms. The Contractor/Vendor is responsible for cleaning and disinfection or may hire a third party for cleaning and disinfection. The Contractor/Vendor must follow CDC guidance for cleaning and disinfection and use products that are effective against the virus that causes COVID-19.
  • The affected Contractor/Vendor employee, worker, visitor, third party, or other individual for whom the Vendor or Contractor is responsible may return to the University work site upon receipt of clearance from his/her healthcare provider or local health department. Clearance procedures must also comply with NJ Department of Health requirements(link is external). The Contractor/Vendor must submit documentation to the University Representative stating that the affected individual has been cleared to return to work (by whom) and in accordance with NJDOH requirements. Please do not submit confidential medical information.
  • Vendor/Contractor employees, workers, visitors, and other parties for whom the Vendor/Contractor is responsible must be provided with a means to review these requirements.   The attached fact sheet has been developed to assist Vendors and Contractors with communication of these requirements to limit transmission of COVID-19 when working on University Property.
