Access: Open to all interested with prior online registration

Join the VTA BART Silicon Valley Phase II industry forum to learn about opportunities to participate in building a one of a kind mega-transit project. The VTA's BART Phase II Project is a 6 mile extension of BART service of Northern California into San Jose in the Santa Clara County that features 5 miles (8km) of single-bore TBM subway tunnelling with four stations plus the creation of transit-oriented communities at each future station area.

VTA's BART extension to Santa Clara County

This informational forum will give an overview on the project, the construction contracts, the procurement opportunities, the project timeline and more.

One of the most innovative features of VTA's BART Phase II project will be the single-bore tunnel that will accommodate both train trackways and the passenger boarding platforms at each underground station.

Firms with expertise in heavy civil construction, tunnelling, track and systems procurement, building demolition, utility relocations and more, are encouraged to register and learn more about the project. VTA encourages SBE and DBE firms to participate.

The project will greatly improve regional connectivity and is estimated to carry 52,000 riders to destinations throughout the San Francisco Bay Area by 2035.

Seattle Ship Canal water quality improvement tunnel project

Seattle Public Utilities and King Country of Seattle are working together to build a 2.7 mile (4.3km) long storage tunnel to reduce the amount of combined sewer overflows into the Lake Washington Ship Canal from the neighborhoods of Ballard, Fremont, Wallingford, and north Queen Anne of Seattle, Washington (Fig 1).

Fig 1. Alignment of the new CSO storage tunnel

During the week of 25 June 2018, 90% design documents and specifications for the 18ft 10in (5.75m) i.d. segmentally lined tunnel will be made available for contractor review and to provide comments or suggested revisions for the estimated US$175-$225 million design-bid-build project.

The 2.7 mile (4.3km) tunnel is to be excavated using a pressurized face TBM at 30ft to 90ft below grade through over-consolidated glacial till and mixed face soils. The TBM is proposed to launch from the 86ft (26m) i.d. West Portal shaft excavated within slurry wall support and in which a pumping station will be built under separate contract. An adjacent pier will be used for loading excavated material for onward disposal.

The TBM will advance to the 40ft (12m) i.d. secant pile supported East Portal shaft where it will be retrieved and facilities and a flushing mechanism will be included in the build-out.

Three intermediate shafts are included in the scope of works: a 11ft (3.3m) diameter shaft will be a drilled excavation and secant piles are proposed for support of the 26ft (8m) and 40ft (12m) diameter shafts.

The project includes a 600ft x 8ft diameter microtunnel (182m x 2.4m) underneath the Ship Canal and three conveyance projects will divert CSO flows to the tunnel. Construction of these elements will include electrical and HVAC vaults, odor control facilities and CSO outfall diversion structures.

Construction activities will be in dense urban commercial and industrial areas primarily in the right-of-way and on Seattle Public Utilities property.

Metro Vancouver contractor outreach event

Metro Vancouver, the regional water and wastewater authority for the greater metropolitan region of Vancouver city in British Columbia, Canada, is progressing a major Stage 5 expansion of its Annacis Island Wastewater Treatment Plant in the city of Delta and adjacent to the Fraser River.

As part of these improvements a new sewage outfall is being built to accommodate greater capacity, improve effluent dispersion into the river, and allow for continued operation after a seismic event.

To facilitate procurement of this new tunneling project, Metro Vancouver has scheduled a contractor outreach event with a live webcast of the event for those who cannot attend in person.

Aerial view: Annacis Island treatment plant

What:	Contractor information session regarding the  Metro Vancouver Annacis Outfall Project
When:	April 3, 2017 from 9:30 to 11:30am
Where:	Metro Vancouver Head Office,  Second Floor Board Room   4330 Kingsway, Burnaby,  British Columbia, Canada
	Live webcast service

Project Description: New outfall to convey and diffuse up to 25.3m³/s of treated wastewater from the Annacis Island Wastewater Treatment plant to Fraser River.

Project includes:

• A 1,200m of 4.2m i.d. tunnel at 40m below ground in soft ground conditions supported by a 250mm-thick precast concrete segmental lining;
• Three on-land shafts, one at 16m i.d. and two at 7m i.d.;
• Approximately 240m of 2.5m diameter diffuser manifold pipe buried in the river bed complete with 24 diffuser ports, each with flexible duck-bill check valves;
• An in-river riser shaft of about 3.8m diameter to connect the deep tunnel to the diffuser manifold built within an anticipated temporary cofferdam supported by king and sheet piles.
