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

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

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
