2. 48 Hour Stand Down

3. Awareness Campaign - Train all PM’s & other Duke departments, contractors on processp

4. Highlight projects with potential for high impact to utilities

5. Indentify High Risk Zones

6. Establish policy on require a vacuum truck to locate gas lines like 44KV lines

When excavating within 30” of an underground utility, the exact

clearance between the edge of the underground utility and the cutting edge of any mechanized equipment

New Duke University Excavation ProgramNew Duke University Excavation Program

Excavation Program

Program is effective immediately

The goals were to document the process have been using and to g p galign it with state law

Additional steps were created to minimize impact or damage to Additional steps were created to minimize impact or damage to utilities in high risk areas

See Excavation Program SOP 1 0 See Excavation Program SOP 1.0

Excavation High Risk Zones or Major Construction Projects

Definitions Definitions– High Risk Zone - any area where damage to the underground utility

infrastructure can have an impact to significant number of buildings on campus, to hospitals, to patient clinics or to research facilitiesMajor Construction Project any new building or building addition on Duke– Major Construction Project - any new building or building addition on Duke property

Duke Project Manager or Supervisor/Manager, at least one week before request for locate of utilities shall request Duke Utilities & Engineeringrequest for locate of utilities, shall request Duke Utilities & Engineering Services (DUES) Operations/Project Manager to have a Pre-Excavation Meeting with all appropriate parties

Meeting shall cover:– Review scope of excavation – Excavation/project schedule – Drawings of planned work g p– Drawings of any logistical issues (traffic impact, etc.) – Name of contractor(s) doing work – Temporary utilities or shutdowns if required– Review Risk Mitigation Plan
