  14. Community Outreach • During COVID-19: virtual meetings, email, phone, mailed notification, social media, weekly construction alerts to about 5,000 subscribers • Before COVID-19: more in-person activities -- business visits, stakeholder briefings, community meetings, and events • Collaborate with partners • Coordinate access and signage • Respond to questions and issues 14

  15. Key Issues and Challenges • Maintaining a high level of safety awareness and accident prevention • Tight budget and limited contingency • Potential construction contract claims • Stakeholder and neighborhood impacts during construction • Unidentified utilities/differing site conditions • Public outreach during construction • Impacts to operations - cutovers 15

  16. Lessons Learned For at-grade construction in City ROW, the agency should consider: Design • Update Agency engineering procedures to include prescriptive requirements for subsurface investigations during planning and design Construction • Contract delivery method – allocation of risk • Consider shared risk on third party utility relocation • Consider the use of incentives to reduce impacts to the community and/or improve schedule performance • Ensure adequate contingencies 16
