Cost Multipliers

Each cost estimate in this Attachment will have two cost multipliers: 

 Recommended Minimum Contingency (30%) 

 Corporate Overheads and Work In Progress Cost (30%) 

The current stage of development of the various conceptual designs provides a sound basis for 

estimating the associated overall design, procurement, and construction costs. However, none of 

this captures the full scope of work, as would be possible if the final detailed design were 

completed, all associated bill of materials developed, and vendor quotes obtained for all 

materials. For this reason, a Recommended Minimum Contingency of 30% was added to all cost 

estimates1

. 

Additionally, a typical cost multiplier of 30% was assumed in order to capture both corporate 

overheads and the cost of carrying the associated funding (i.e., a Corporate Overheads and Work 

In Progress Cost).
