Leveraging the Operational and Cost Advantages of Hot In-place Recycling for a Single-Runway Airfield Pavement Rehabilitation Project at Kelowna International Airport

摘要

In 2011, the City of Kelowna tendered the Rehabilitation of Runway 16-34, Taxiways A, B and C. Thetender included the resurfacing of Runway 16-34, widening and resurfacing of Taxiway C, andresurfacing of Taxiways A and B at their existing dimensions. The tenders received were about 40percent over budget, and the project was subsequently cancelled.SNC Lavalin Inc. then completed a project review and developed a revised 2012 Work Plan for the projectincluding a less operationally disruptive resurfacing approach, eliminating some requirements that wereperceived as onerous by Contractors, and removing non-contiguous work elements.In January 2012, the runway resurfacing project was re-tendered as a stand-alone Hot In-place Recycling(HIR) project. The Taxiway A, B and C rehabilitation work was re-tendered separately in May 2012.Because of these and other changes, the cost of the runway and taxiway rehabilitation projects wasreduced from the 2011 low-bid tender of $6.256 Million, to a new, combined cost of $2.893 Million. Bothprojects were completed in the summer of 2012, ahead of schedule, under budget, and with no operationaldisruptions.
