Sea to Sky Highway Improvement Project

Introduction

This report examines, from a construction management point of view, the Sea to Sky Highway Improvements Project. The project was initiated in 2004 and completed in 2009. The impetus for the project was the awarding of the 2010 Winter Olympic Games being awarded to Vancouver/Whistler British Columbia in 2003.

The report includes;
1. Background information describing the age of the existing highway, some of the engineering difficulties associated with the proposed improvements, and the anticipated benefits of the improvement project. 2. The selection process describes the method used to select the preferred proponent. Information is provided on the five stages of selection, starting with the Registration of Interest and culminating in the Contract Award. 3. A closer look at the Request for Proposal (RFP) portion of the selection process follows. The three criteria applied to the RFP process and how the criteria were scored is discussed. 4. The Final Contract is examined and describes the roles and expectations of the parties involved. This section gives specific information on the terms of the contract, incentives and penalties, defines roles and obligations. 5. The environmental portion discusses enhancements that were enabled by the highway upgrade. This sections describes the environmental measures that were mandated and additional value-added enhancements. 6. The conclusion describes some of the benefits of the project. Unique aspects, and the combination of construction management approaches employed of the project are discussed.

1. Background and Scope

The Sea-to-Sky Highway is a 96 km long section of highway that links communities from West Vancouver to Whistler British Columbia. Set in a mountain landscape, the highway presented complex engineering and construction challenges. The highway clings to the rugged, mountainous coastline of Howe Sound to Squamish, where it veers away from the coast and into the Coast Mountains to Whistler. The highway was two lanes, with steep slopes and blind curves. It has been the scene of dozens of fatal accidents over the years.

The southern portion of the highway was built in 1959. This portion connected communities from Horseshoe Bay to Squamish. The extension to Whistler was completed in 1966. Through the 1980`s and 1990`s there were numerous studies on expansion to the highway. With the awarding of the Olympic Games in July, 2003, the British Columbia Ministry of Transportation (MoT) initiated the Sea to Sky Highway Improvement Program.

Figure 1. Half Bridge Construction
In 2004 a 0.9 km test section and two 7 km design-build sections provided insight on construction, geotechnical, and traffic issues. The biggest challenge faced was that there was no land where two lanes were to be added. It was necessary to figure out how to either suspend the highway or build retaining walls from the bottom up. The Test Section was a particularly difficult piece of the highway. The original design called for a narrow, 2-lane section to be expanded to four lanes by constructing a split grade road with retaining walls at both the outside and centerline of the highway. The project was constrained by a high bluff on the uphill...
