There are multiple positions involved including subs, architects, engineers and owner(s).

● Meetings (weekly) -project goal priorities will change frequently

● Proper logs, change orders and other documentation such as electronic & hard memorandums / reports determine how smoothly a project can run

● Use methods such as P6, email, & phone calls

● Not only does the internal circle of the project need to be in healthy communication with each other, but also the outsiders involved (stakeholders)

● Different groups of people will be impacted by the project; it is important to keep them updated so that their everyday lives will not be negatively affected ○ Noise & traffic are typically the main issues Communication Plan Public Information ● Information Card handed out at public meetings (Oakland Transportation Management Assoc.)

● Project Description

● Bridge Construction Dates -total duration of ~24 mo.

○ month #1: bridge closes to public & contractor begins physical work

○ month #3: bridge implosion (including part time closure of I-376 Parkway East)

○ month #4 & on: construction of bridge

● Pedestrian traffic restricted from bridge - pedestrian/bicycle detour route implemented

● General traffic detoured around bridge with the aid of a posted detour
