Building Access

Access: The building is open from 8am to 7pm, Monday through Friday, and is locked at all other times including University holidays. You may request after hours proxcard access for the exterior doors. Send an e-mail to Pamela DelOrefice with your name and ID number from the front of your Princeton ID card (your TigerCard). Only those listed below will be granted access. The TigerCard office automatically grants access to all Computer Science undergraduate and graduate students upon arrival.

After Hours: Those authorized to use the Computer Science Building after hours are:

  • Department of Computer Science faculty, staff and graduate students.
  • Undergraduate computer science majors.
  • Others having authorization to use academic facilities inside the building.

Access after hours to the 2nd, 3rd and 4th floors is restricted. Those issued a physical key to an office or lab in the building can use their key to in the elevator, at the top of the grand staircase, and to the doors of the two stairwells. Those who were not issued a physical key but who are authorized to access the upper floors (e.g., CS undergraduates) can use their TigerCard in the elevator and at the top of the grand staircase. (The CS Guide contains additional details about the Salto system used for TigerCard access inside the building.) When not otherwise reserved, the Tea Room and seminar rooms are available for study.

Key Policy

Office keys are issued under the agreement that the holder will reimburse the Department of Computer Science $100 upon failure to return any key(s) issued to them. The Department of Computer Science will bill the student account at Princeton University for the loss. Lost keys will be replaced at a cost of $30 per loss. The replacement fee must be paid in cash or check prior to the key being re-issued. Excessive requests for replacement keys may result in the need to replace the room core or multiple cores. Many department keys have multiple layer access such as unlocking main doors in addition to individual offices. Lost keys compromise the security of the entire building not just the office to which they are issued. The cost of these re-cores will be the responsibility of the keyholder.

Keys are to be returned to Pamela DelOrefice. To return keys after hours, place the key in an envelope, write your name on the outside and slide it under the door to Room 212.

Additionally, the department must be reimbursed for postage in a timely manner. Students who fail to reimburse the department will have mail returned to the sender.

Packages that are too large to fit in your mailbox will be left on the table in room 232. Due to limited space please check the table often if you are expecting a package.

Please take advantage of electronic delivery notification features provided by shippers.

Outgoing shipments may be sent using any one of the department’s carriers. The department maintains accounts with the USPS, UPS, Fedex and DHL.

Research and instructional items may be purchased through the Business Manager's office. Purchases must be approved by your adviser, faculty sponsor or the department. In general, you may send an e-mail to Pamela DelOrefice, (cc: your adviser) with a description of the item, part number, quantity and suggested vendor. Purchases using sponsored research funds require a comment to explain what it is that you are purchasing and how it is relevant to the project. If the item is a specialty item or requires particular specifications it is suggested that you obtain a quote from the vendor prior to submitting your request. Orders over $2,500 require three competitive quotes. The University Purchasing Department continually negotiates special pricing with many vendors and maintains purchasing contracts with those vendors. Your request may be forwarded to a contract vendor for competitive pricing. You will be notified via e-mail once your order has been placed.

Computer Purchases

Computers may not be purchased with personal funds and will not be reimbursed under any circumstances. Princeton University maintains contracts with the vendors listed below. Please contact Pamela DelOrefice for any computer purchases. Alternate vendors may be used by obtaining a quote directly from the vendor. It is important to note that for quote comparisons, University contracts often contain additional benefits that are not obvious.
