A Leader in Heavy Underground Construction SECOND NARROWS WATER SUPPLY, VANCOUVER, BC NAVI GATION THROUGH CHANGING GEOLOGY The new Second Narrows water supply tunnel will be excavated deep under the Burrard Inlet, just east of the Ironworker’s Memorial Bridge. Due to complex geological conditions, the first ever Mixshield in Canada will be utilized in this project. With project-specific technology and s u p p o r t from the local Herrenknecht subsidiary, the 1,100 meters of new tunnel will replace the existing aging mains that convey drinking water. herrenknecht.com/secondnarrows Client: Metro Vancouver Contractor: Traylor-Aecon General Partnership INSIDE this issue OCTOBER 2020 COVER STORY 10 Utilization of Underground Space Promotes Urban Development By Nasri Munfah A look at the role of subway construction and development in today’s cities.

  • Policy Brief
    Policy Brief Moving Toward More Accessible and Productive Transportation in the Puget Sound By Wendell Cox, Principal, Demographia (Wendell Cox Consultancy) October 2019 Key Findings 1. The overwhelming share of population and employment in the Puget Sound is outside the city of Seattle. Even with the city of Seattle’s unprecedented population and employment growth since 2010, a sizable majority of new residents and employment have located outside the city. 2. The Puget Sound region is dispersed, both in employment and residences. While downtown Seattle is the strongest Puget Sound Regional Council (PSRC) employment center and has experienced astounding growth since 2010, more than 85 percent of employment is outside downtown. 3. The “Amazon Boom” has brought unprecedented employment growth to downtown Seattle and seems unlikely to play as strong a role in the future. However, even with the “Amazon Boom,” nearly 60 percent of employment growth has been outside the city of Seattle since 2010. 4. Autos are used by more than two-thirds of commuters to work trip locations throughout the Puget Sound, with a three-quarters share outside the city of Seattle and just shy of a 50 percent share in the city of Seattle. 5. Transit serves a principally niche market, with 48 percent of the commuting to downtown Seattle, and a 9.3 percent share to the rest of the city. Only 3.5 percent of work trips to destinations in the rest of the Puget Sound are on transit. 6. Downtown dominates transit commuting. PSRC employment centers outside the city of Seattle exhibit transit commuting characteristics more reflective of suburban areas outside centers, with virtually no realistic potential for reducing vehicle miles through expanding transportation choices.

  • Making Transit Work on the Waterfront
    Southend Pathways Making transit work on the waterfront After the State Route 99 tunnel project is complete and the Columbia Street and Seneca Street ramps have been removed, Metro will need a fast, reliable transit pathway for buses to and from downtown Seattle to replace the connection provided today by the Alaskan Way Viaduct. We’re asking the City of Seattle to provide a continuous priority pathway for transit as part of its Central Waterfront Project, with all-day, two-way bus lanes on Alaskan Way from Dearborn Street to Columbia Street and Third Avenue. The city faces a challenge as it tries to meet the needs of competing interests on the waterfront—including ferry lines, parking, and business access. There are limited options for prioritizing bus riders on the waterfront. But this pathway is crucial to maintaining the speed and reliability of bus service for riders from southwest and northwest Seattle neighborhoods to, from, and through downtown Seattle. A fast, reliable pathway is essential to… Meet the needs of thousands of transit riders who rely on service in this corridor. • The viaduct carries 22,000 bus riders per day. This total is similar to those for Link light rail (27,000) and the E3 Busway in SODO (24,000) – two facilities where transit is prioritized. Maintain and grow ridership in this corridor. • Use of the RapidRide C and D Lines has grown significantly since they began service in fall 2012. C Line ridership is up 33%; D Line ridership is up 9%. • By 2016, Metro buses will carry an estimated 30,000 riders in and out of downtown on the new Alaskan Way surface street—a number equal to the anticipated number of vehicles making the same commute.

During operation, a large diameter tube allows for stacked deck configuration with shafts dropped to platform level (no station caverns). The extensive information has been compiled on innovative TBM tunneling projects such as the Barcelona Line 9, where the concept of continuous station has been used for the first time, stormwater management and roadway tunnel in Malaysia, where the floodwater bypass tunnel and the road tunnel are incorporated in a single bore tunnel.
