Idea (Short Name)	Idea (Detailed Description)	Implementation Details (Barriers, Skill Set Coordination, etc.)
Precast vs. cast-in-place.	Precast retaining walls and structures, temporary ramps, etc. Look for areas that affect traffic the most to speed up the time of disruption.	Early let for precast?
Completion time.	Keep completion time to an absolute minimum.	May force them to have more crews. May pay more money - likely worth it.
Jack critical storm sewer (96 in).	Possibly less time and impact to traffic for critical storm sewer sections.	What are costs? Possibly use sheet piling or put proposed storm in median next to existing storm. Which location is more beneficial/cost effective?
Divert storm.	Avoid upgrade to 96 in storm sewer and surge basin.
Closures.	Minimize major movement closures to 8 weeks.	This applies to through volumes and major ramp movements. Local ramps could be closed for more time. Nights and weekends for I-35W closures.
Cross sections.	Strive for cross section uniformity to save construction time.	Use concrete shoulders between mainline pavement and curb and gutter to save time.
