Title: Peak 2 Peak Gondola
Content:   Whistler-Blackcomb broke ground for the Peak 2 Peak Gondola in a ceremony on May 21, 2007. The Doppelmayr Garaventa Group would supply the gondola itself and Timberline Construction was the general contractor and Glotman Simpson were the Consulting Engineers. Fatzer AG of Switzerland would make the four track cables and one haul rope that would carry the gondolas across the valley while CWA, also of Switzerland, would build the 28 gondola cabins. 80 workers from Whistler Blackcomb, Doppelmayr Garaventa, Timberline Construction and North Construction worked throughout the summer of 2007. Work completed on the Blackcomb side by that summer included the relocation

Content:   The Peak 2 Peak Gondola is a tricable gondola lift at Whistler Blackcomb Resort in Whistler, British Columbia, linking Whistler Mountain's Roundhouse Lodge with Blackcomb Mountain's Rendezvous Lodge. It is the first lift to join the two side-by-side mountains. It held the world record for the longest free span between ropeway towers—3.03 kilometres (1.88 miles) until 2017 when the Eibsee Cable Car exceeded it by 189m. It is still the highest point above the ground—436 metres (1,430 feet.) (A temporary aerial tramway in Switzerland used between 1979 and 1986 had larger span.) The Peak 2 Peak Gondola was built by the Doppelmayr Garaventa Group in 2007 and 2008 at a cost of CDN$51 million. The Peak 2 Peak Gondola is the first Doppelmayr "3S" tri-cable lift in North America; there are four similar but smaller lifts in Europe which were built in 1991, 1994, 2002, 2004 and 2010 in Switzerland, Austria, France and Germany. Whistler-Blackcomb has touted the gondola as an iconic attraction and uses it to transport skiers in the winter months as well as sightseers year round.

Content:  The grand opening ceremony on December 12, 2008 featured Steve Podborski as emcee and Red Bull Air Force members BASE jumping from the middle of the gondola. The Peak 2 Peak Gondola was the subject of a 2009 Discovery Channel documentary. Crews began filming the project during groundbreaking in May 2007. The documentary aired at 9 pm on December 23 and at 2 am on December 24, 2009, on Discovery Channel Canada. It was titled "Peak 2 Peak: Building the Worlds Biggest Gondola". The gondola was also featured in the History Channel's show Modern Marvels in the episode "Winter Tech," which showed the technology behind the Vancouver 2010 Winter Olympic Games. On February 6, 2014, Graham Dickinson carried out an illegal

Content:  The cables were manufactured by Fatzer AG, a Swiss company that develops, manufactures and markets wire ropes worldwide. The Peak 2 Peak cables include four stationary track ropes, two in each direction, which act like railroad tracks for the cabins. Each track rope weighs approximately 90 metric tonnes. There is a single haul rope which moves in a continuous loop and pulls the cabins. This cable weighs more than 80 metric tonnes. There are a total of 26.5 km of cable on the Peak 2 Peak Gondola.

Content:  86% of summer visitors would use the gondola at least once. HSBC Bank Canada and Scotia Capital agreed to provide Intrawest with financing for the project, allowing it to move forward. Intrawest announced the gondola project to employees and the Municipality of Whistler’s Council on September 19, 2005, and held a community open house shortly thereafter. At the time, construction was expected to start in the summer of 2006 and continue for 2 years for an opening for the 2007-2008 ski season. On March 30, 2006, it was announced that construction would be delayed by one year. Whistler Blackcomb announced on April 17, 2007, that groundbreaking would occur in May 2007.

The splicing process took 14 workers from Whistler-Blackcomb and Doppelmayr Garaventa over 15 hours to complete. The 28 sky cabins arrived in Whistler starting on August 26. The first twelve cabins crossed the span on September 19, 2008 with a single Doppelmayr engineer, Mathias Zudrell, aboard. The remaining cabins were put on line and the system underwent extensive testing until its Grand Opening on December 12, 2008.

Content:  The Peak 2 Peak Gondola has a number of unique safety systems beyond what a normal ski lift features. The gondola has high wind stability and is designed to operate in winds up to 80 km/h. Whistler-Blackcomb has called the Peak 2 Peak Gondola the most wind tolerant lift on Whistler Blackcomb. Testing at other Doppelmayr 3S installations have measured sustained winds at 120 km/h (75 mph) with no decrease in performance. The lift is powered by an electric motor on Whistler Mountain; however an auxiliary diesel engine can take over in the case of primary engine failure or if there is a power outage. The lift also has a redundant braking system. Both bullwheels have emergency brakes to stop the gondola if

Content:  The Peak 2 Peak Gondola terminal buildings are the two largest lift terminals in the world. To create the concrete footings, platforms, masts, and columns, 4000 m3 of concrete had to be trucked and helicoptered up the mountains. The 12000 ft2 Whistler terminal, which houses the drive motors and backup engines in an underground vault is 26 metres (85 feet) wide and 42 metres (138 feet) long and has 228 tonnes of steel. The 14000 sqft Blackcomb Terminal is 26 metres (85 feet) wide and 48 metres (158 feet) long and contains 279 tonnes of steel. The Blackcomb terminal can house 15 cabins, the Whistler terminal 13 cabins in a cabin parking area when the system is not in use.
