The T is planned to eventually serve the full line between Harlem—th Street and Hanover Squareand the Q will serve the line between 72nd Street and Harlem—th Street. It is double-tracked along its entire length, with tracks in parallel tubes bored by tunnel boring machinesand central island platforms at all stations.

The primary focus of the technical program is to add value to the industry through examination of the most innovative practices and products currently Ny nj crossrail report use.
The program committee is dedicated to shining a light on new, novel and unique innovations and projects. The emphasis is on real-life application of techniques as applied to real problems.
View a complete list of technical sessions below. Monday, June 5, 8: Brandt, Traylor Bros, Inc. 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 project was initiated, managed and supervised by the owner Transport Authority Qatar Rail. Solecki, Hatch Mississauga, Ontario; I. 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.
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.
Port Mann Water Supply Tunnel: Lessons for the Future G. The contracting and management issues associated with delivering the project have been as complex and time consuming as some of the design and construction challenges.
As well as explaining how the design and construction challenges were successfully addressed, the paper presents how Metro Vancouver approached contractor procurement through prequalification and negotiated proposal phases, presents the risk management approach and project team structure, and describes how the lessons learned on the project can be applied to future tunnel projects in the region.
Newby, CDM Smith, Burnaby, British Columbia, Canada Overexcavation during pressurized face tunneling is a risk factor with respect to unplanned surface deformation and damage to existing installations above the tunnel.
Risk management typically includes surface and subsurface deformation monitoring of critical areas identified during planning and design.
However, continuously reconciling material flows during the mining process is a risk management tool that allows recognizing and correcting causal trends before effects are observed. This paper describes the reconciliation methods for different TBM types, provides project examples from Seattle area tunnels, and discusses risk management implementation approaches involving the owner, designer, contractor, and third party asset holders.
The structure will be replaced by cut and cover approach structures and a single, 1. DC Clean Rivers Project: A total of 15 shafts with diameters up to feet 45 m and depths up to feet 59 m ; three large-diameter tunnels have been constructed in three contract divisions Divisions A, H, and P and procurement of a fourth tunnel project Division J is underway.
The projects of the LTCP are located in the crowded urban environments and extensive geotechnical instrumentation programs were installed to monitor performance of shaft and tunnel construction for the protection of the critical infrastructure, including DC Metro, bridges, water lines, sewers, etc.The New York-New Jersey CrossRail project would involve a capital “R”, as well as a pair of new tunnels under the metropolis.
These would run from Newark in New Jersey, through Penn Station and out to Jamaica in the suburbs of Queens. Oct 12, · Crossrail: a passenger rail program, much of it underground in new tunnels, with 73 miles of new track and 40 new stations, connecting a multitude of subway and rail lines across London and its suburbs, scheduled to be completed in (Proposals for Crossrail 2 and Crossrail 3 are being floated also);.
