Pardee Tunnel Chemical Feed Shaft Design, Valley Springs, CA
McMillen Jacobs has been selected to provide engineering services for the East Bay Municipal Utility District’s Pardee Tunnel Chemical Feed Shaft Design Project. The project involves construction of two 300-foot-deep (91 m), approximately 16-inch-diameter shafts (405 mm) in volcanic rock that penetrate onto the crown of the Pardee Tunnel, to house a total of four, 5-inch (125 mm) chemical lines. The shafts will be identical and are expected be sited between 50 and 100 feet (15−30 m) of each other. Our scope of work includes detailed design of the shafts and tunnel penetrations, construction risk management and planning services for tunnel access, and optional design services for additional facility improvements and construction sequencing support.
WestConnex Rozelle Interchange, Sydney, Australia
McMillen Jacobs was selected to provide detailed design services to the John Holland and CPB Contractors (JHCPB) JV for the delivery of the WestConnex Rozelle Interchange design and construct contract. This is the largest, most complex stage of WestConnex, linking all segments of Sydney’s busiest motorway networks. With this win, McMillen Jacobs will be the only tunnel consultant to have contributed to all stages of the WestConnex Project (Stages 1, 2, and 3). Located in Sydney’s inner west suburb, the Rozelle Interchange and Iron Cove Link is part of the new M4-M5 Link and will provide a new underground motorway interchange to the City West Link and provide an underground bypass of Victoria Road between Iron Cove Bridge and Anzac Bridge, with links to the future Western Harbour Tunnel.
Snell Algies Outfall Pipeline, Auckland, New Zealand
The McConnell Dowell/McMillen Jacob Associates team has been awarded the design and construction of Watercare’s Snells Algies outfall pipeline. The new outfall will increase capacity to meet the future demand in the growing populations of Warkworth, Snells Beach, Algies Bay, and Martins Bay. The project consists of approximately 4.3 kilometers (2.7 mi) of 630-millimeter-diameter (25 in.) pipeline from Snells Algies to South of Martins Bay, 2.2 kilometers (1.4 mi) of 1.2-meter-diameter (4 ft) pipe installed using the Direct Pipe® system as a “single pass” solution, and a 230-meter (755 ft) marine dig and lay section.
