The Michigan Department of Transportation (MDOT) intends on piloting a new method of fixed price/variable scope contracting on a capital preventative maintenance project on I-94. The project is expected to be let in June 2013 with construction beginning after July 4, 2013 and being completed in the 2013 construction season. The project is on I-94 between M-14 and Carpenter Road near Ann Arbor.
Funding is not available to complete the entire project and MDOT is piloting a method to construct as much of the project this year within the available funding limits. To accomplish this MDOT is piloting a concept with the following procedures.
The Project Log will include items of work broken into different priorities, and a description of the work in each priority is listed below. Each priority in the Project Log includes the pay items and estimated quantities for the entire project. The schedule of items contractors will bid on will be based only on Priority 1. MDOT’s estimate for Priority 1 work is approximately equal to the amount of funding available. Contractors will submit a bid for this work as they would on any traditional MDOT project.
Click here for a copy of the draft Notice to Bidder that describes the unique parts of this project. The unique component related to fixed price/variable scope is that MDOT intends on managing the project during construction so the final construction cost is equal to the available funding. For example, if MDOT has approximately $4,000,000 and the low bid comes in at $3,900,000, all of the work in Priority 1 will be completed and $100,000 will be added to project after the Award in order to complete a portion of Priority 2. If the low bid is $4,100,000, portions of the work in Priority 1 will not be constructed so the final construction cost is $4,000,000. A second unique component is that MDOT is including the ability to add funding to the project to complete additional work if additional funding becomes available during construction.
Description of Work by Priority
Priority 1:
- Maintaining traffic quantities for all Priorities
- Mobilization for all Priorities
