Turner & Townsend to oversee cost risk assessment on new Kuala Lumpur MRT construction project
Construction work on MRT Sungai Buloh- Serdang-Putrajaya Line, the second of three mass rapid transit (MRT) railway systems to be constructed in the Kuala Lumpur area of Malaysia, is expected to start in Spring 2016.

The 52.2km railway line, which is being developed by Mass Rapid Transit Corporation, will be fully operational by 2022, and will include 37 stations, with 26 of them elevated and eleven underground.

Global programme management and construction consultancy, Turner & Townsend has been appointed to deliver quantitative cost risk assessment every six months for the initial three years, with an extension for the full duration of the project subject to a review.

The railway line, which will operate trains at speeds of 100km/h, will enable an endto- end journey time of 85 minutes and will eventually serve a population of two million with an estimated 533,000 passengers using the system daily. It is part of a government initiative to alleviate road traffic congestion, contribute to a cleaner environment, boost the economy and raise living standards.

Maryland Purple Line light rail transit project progresses to design-build stage
The new 16-mile Maryland Purple Line light rail transit system planned for the Washington Metropolitan Region has come a step closer. Purple Line Transit Partners has been selected to design-build, finance, operate and maintain the line on behalf of the Maryland Department of Transportation and the Maryland Transit Administration.

The partnership comprises of Fluor Enterprises, Meridiam Infrastructure Purple Line, LLC, and Star America Purple Line, LLC.

The $2bn Purple Line Light Rail system includes 21 stations along a 16-mile alignment that extends from Bethesda in Montgomery County to New Carrollton in Prince George’s County. It will connect with several existing transit providers and improve mobility to major economic and job centres, as well as the University of Maryland in College Park. The project will support community revitalisation and transit-oriented development along the corridor.

The Purple Line Transit Constructors team will begin design and construction later this year with passenger service scheduled for early 2022. Following the construction, Purple Line Transit Operators, comprising Fluor Enterprises, Alternate Concepts, and CAF USA, will provide 30 years of operations and maintenance services.

Hans Dekker, president of Fluor’s infrastructure business, said: “We are proud to enter into a long-term partnership with the state of Maryland and will design, build, finance, operate and maintain this world-class transit link using our proven integrated life-cycle approach and experience.”

Rotork to fulfil vital fire safety role on the Istanbul Metro
The Istanbul subway system in Turkey is undergoing a significant expansion programme involving 900 kilometres of new routes that are due for completion by 2023. Tunnels on the new routes are fitted with ventilation dampers in sizes up to 2m square. To meet stringent safety standards, the actuators operating these dampers must be able to rapidly close them and shut off the airflow in the event of a fire.

High temperature specification Rotork RC200 scotch-yoke pneumatic actuators have been selected for this application due to their compact design, fast operating capability, long term reliability and minimum maintenance requirement. In addition, the actuators had to pass the stringent temperature and cycling tests required to meet the high level of safety demanded by the application.
