Governor John Volpe interceded in the s to change the design of the last section of the Central Artery putting it underground through the Dewey Square Tunnel. While traffic moved somewhat better, the other problems remained. There was chronic congestion on the Central Artery Ian elevated six-lane highway through the center of downtown Boston, which was, in the words of Pete Sigmund, "like a funnel full of slowly-moving, or stopped, cars and swearing motorists.

Schrader, Herrenknecht AG, Germany With the construction of the Metro Doha in the State of Qatar a vision is accomplished to establish a modern, safe, efficient and integrated public transportation network.

Upon final completion of multiple phases, the network will comprise four metro lines with a length of km and stations. Phase 1 comprises km of underground tunnels 56km twin tube tunnels and a total of 21 Earth Pressure Balance Tunnel Boring EPB machines were deployed by the four different Joint Ventures.

The issue of cutterhead inspection and maintenance in Earth Pressure Balance EPB tunneling can be a dangerous, time consuming, and costly process, particularly when the ground is unstable. Severe primary and secondary wear on the cutters has been seen in some of the projects in glacial soils including Seattle area.

Impact of conditioned soil parameters on tool wear in soft ground tunneling M.

About the author

Hedayatzadeh, Politecnico di Torino university, Italy; J. Peila, Politecnico di Torino university, Italy The use of mechanized shielded tunnel boring machines TBMshas grown rapidly in various soft ground tunneling projects.

In the recent years, Earth Pressure Balance EPB shields have been successfully used in many tunneling projects in urban areas while the range of soil types that it can handle has expanded. One of the critical issues for successful EPB tunneling is the use of proper soil conditioning.

The effects of soil abrasiveness on primary and secondary wear of tools and machine components is one of the most important aspects of soft ground tunneling, estimation and assessment of, costs, and schedule of a project. Among the parameters that can affect tool wear, soil conditioning is the most critical one that can be controlled by the operators.

To assess the impact of the soil conditioning on tool wear, a new test apparatus with new propeller has been developed. Specific test procedure has been developed and many tests have been conducted. Review of the initial test results shows that soil conditioning reduces wear of tool and other machine parts.

More tests are underway to evaluate the effect of soil conditioning on machine torque requirements through a parametric study. To minimize surface impacts, the design-build team, Regional Connector Constructor RCCproposed an alternative tieback removal concept comprising a vertical shaft and mined adit.

This paper describes the use of Building Information Modeling as a powerful design tool to optimize the location, size and alignment of the concept and demonstrates its feasibility to the Project Owner, LA Metro, and describes the shaft and adit construction in a dense urban setting and the tieback removal process.Our research aims to bridge the gap by exploring the relation between the public feature of Megaproject and its risk management policy option.

Under the project risk management framework, the case study of Scottish Parliament Building project focuses on the stakeholder intervenes during the whole process.

MEGAPROJECT Case Study Basic Project Information 2 Project Status (i.e.. initiation, planning, construction, operation, dismantling) All the 25 single zones under the project have passed feasibility studies and design of the land and infrastructure.

10 of them are with invested money for infrastructure and started accumulation of the business. The Central Artery/Tunnel Project (CA/T), known unofficially as the Big Dig, was a megaproject in Boston that rerouted the Central Artery of Interstate 93, the chief highway through the heart of the city, into the mile ( km) Thomas P.
