Paper Title:

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

Late in 2011, the City of Kelowna engaged SNC‐Lavalin Inc. to review, value engineer and recommend changes to an earlier design and tender package for runway and taxiway rehabilitation works at the Kelowna International Airport.

The objective of the review and value engineering process was to develop a solution that was less disruptive to airport operations and to reduce costs. This first objective was critical, as the Kelowna Airport is a single‐runway airfield facility with frequent scheduled air service, and cannot tolerate disruptions or delays to daily aircraft operations.

The previous design and Work Plan called for resurfacing runway 16‐34 using a combination of Mill and Fill and Hot In‐place Recycling (HIR), widening and resurfacing of taxiway C, and resurfacing of taxiways A and B at their existing dimensions.

Through the value engineering exercise, SNC‐Lavalin was able to develop a revised Work Plan for the airside pavement resurfacing works with reduced risk of airfield operational disruption, eliminate onerous daily and completion penalties, and remove non‐contiguous work elements.

In early 2012, with Tendering and Construction Management support from SNC‐Lavalin, the City retendered and executed the Runway 16‐34 and the Taxiway A, B, and C Rehabilitation projects. The Runway Rehabilitation project was tendered as a discrete, stand‐alone, full width, Hot In‐place Recycling treatment, reducing the daily and completion delay risks, potential for operational disruption, and project costs. The Taxiway A, B and C Rehabilitation work was re‐tendered as a completely separate project.

As a result of these changes, the City of Kelowna was able to complete the works with a savings of roughly $3.5 Million, about half of the 2011 low‐bid tender of $6,600,000. Both projects were successfully completed in the summer of 2012, with no aircraft delays or operational disruptions. Additionally, both were completed ahead of schedule, and under budget.

The paper will include a summary of the project, from the initial 2011 scope and tender, through the 2012 revised scope and tender, and project execution and completion. It will describe the rehabilitation methodology employed, the environmental and operational benefits associated with using the selected methodologies, and the resulting costs/cost savings. It will also discuss the construction quality control and quality assurance test data obtained during the runway HIR rehabilitation work.
