A. General -> Montlake Landfill	For projects located east of Montlake Boulevard, all design proposals shall address specific local challenges and must be approved by Engineering Services.

This is particularly problematic around connections between individual buildings and central campus utility systems. Consultants shall discuss any anticipated issues with ES prior to approval.	None
N. Ground Disturbance and Utility Locates	Prior to any ground disturbance at the UW Seattle Campus, it is mandatory to initiate a utility locate by calling 811. For inquiries regarding this process, contact the Building and Utility Shutdowns and Utility Locates Manager at 206-543-7158 or kd79coop@uw.edu. Buried facilities may be present under roads, sidewalks, lawns, and planting beds. A utility locate is required to ensure any publicly or University owned underground lines are identified and marked, enabling safe excavation and avoidance of the lines. This practice is crucial to prevent not only damage to utility lines, but also property damage and personal injuries that could result from breaking a line. Compliance with locate requirements is legally mandated for all excavation activities, ranging from planting bulbs or flowers to large-scale excavations for building foundations. The University of Washington adheres to the WA State Dig Law and Industry Best Practices. Additional mandatory protocols include: • Maintaining an up-to-date LIVE utility map for the project. • Ensuring that shutoffs for all systems potentially impacted by excavation activities remain accessible. In the event of any utility strike, regardless of severity, immediate notification is required – contact the Seattle Campus Building and Utility Shutdowns and Utility Locates Manager. Contractors and vendors must also notify their University of Washington contract manager. Detailed Process Overview: 1. Locate request is submitted to 811, generating a time-stamped ticket. 2. Ticket is sent to all relevant utilities and facilities within the defined locate polygons, which include the main campus, UW Hospital, ICA, west campus, among others. 3. If a locate is necessary the appropriate shop or utility provider is notified. This may include the UW High Voltage Shop, Irrigation Shop, BIT, Heavy Equipment Shop, Zone Electricians, Shop 24, construction and project managers, and the UW locate contractor. 4. The UW locate contractor marks the UW water distribution, sewer, storm drains, low voltage, chilled water, steam, and natural gas systems. 5. Following marking, the Building and Utility Shutdowns and Utility Locates Manager verifies at the job site that all University facilities are correctly marked. This completes UW’s responsibility as a facility owner. 6. The ticket is updated to reflect the completion of marking for UW facilities. Note that additional utilities such as Seattle City Light, Seattle Public Utilities, Seattle Department of Transportation, Puget Sound Energy, Metro, Lumen, and numerous fiber providers may also be present on our property.
