Factors that may Impact Cost
- Size of project
- Project Phasing: Multiple location projects vs. slingle location projects (5-mile job on 1 road vs. 1-mile job in 5 different places)
- Traffic staging (easier to do 1 lane the full job length, harder to do both lanes to the same point each day)
- Urban work (manholes / catch basins, intersection control add to cost) vs rural work
- Night work (costs more for labor but less traffic disruptions)
- Bidding/Tendering date vs. completion date and number of working days
- Raw material pricing (emulsion / AC)
- Competitive bids (number of contractors in Region)
Decrease Cost Without Affecting Quality
- Doing geotech analysis to see if road is good candidate (drainage, subgrade, structure, etc)
- Provide mix design with Letting
- Early letting closing (ideally Oct-Dec for the next year’s work)
- Clear, constructible specs
- Fair assignment of risk
- Consistent annual CR program
