Pre-cast pier construction
Lessons learned:◦ Detail additional room
for bar couplers◦ Comprehensive
survey control◦ Steel templates for
bar steel◦ Match cast pre-cast
elements

Keys to Project Success◦ Public outreach and
involvement◦ Close coordination with
prime and heavy lifter◦ Travel path preparation
and planning◦ Project partnering with
stakeholders
