• Construction • 2 year long project (Fabrication the largest portion of this). • Onsite work limited to 3 month period of time. Aprox 6 weeks pre-closure, and approx. 6 weeks post closure. • Lots of time to develop plans and systems, not a lot of time to react to issues once on-site. • Fire Impact • Closure delayed due to wildfire and need to leave evacuation routes open. • Traffic Staging • Very Complex traffic staging, dealing with both directions of I5 at once. • Work could not start until traffic staging was complete • Continual monitoring and twice daily shifts during closure. • Daily Stakeholder meetings (lots of meetings) • So many different stakeholders, the meetings were endless. • Closure Schedule • Around the clock operations through completion CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION CONSTRUCTION & F ABRICATION
