The use of alternate bids with life cycle cost as part of the tender process for pavement choice evaluation has been evolving in Canada since the first contract tendered in 2001. This paper will review the history of how alternate tenders with a life cycle cost component were started in Ontario based on the initial Life Cycle Cost study of 1995. The paper will identify the key points to consider when performing a life cycle cost analysis (LCCA) including: use of equivalent bids, selection of accurate maintenance and rehabilitation (M&R) schedules, selection of discount rate, inclusion of user costs, and inclusion of sustainability issues. The advantage of utilizing a two pavement system (asphalt and concrete) is also discussed. For comparison, information will also be provided on Quebec's White Grey Black policy for pavement selection. For the covering abstract of the conference see ITRD number E211521.
