The Dubai Metro Project
General
The project is for the design and build of two lines: the Red Line and the Green Line with 45 stations over 75 km. The Red Line further contains Airport Terminal 1 and Airport Terminal 3 stations that are not within the scope of this project. There are four types of overground stations depending on location. The interior design of all stations is based on one of the four elements: earth, fire, air and water. There are two stations with a special heritage design located at Al Ras (Heritage Water) and at Al Ghubaiba (Heritage Earth).
Manpower
The peak of the manpower was in April 2009 at 35,591 people. This includes direct and subcontractor labourers, staff, engineers and management. Over 43 nationalities were employed at the time including: American, Australian, Bangladeshi, British, Canadian, Chinese, Egyptian, Emirati, Filipino, French, German, Greek, Hong Kong – Chinese, Indian, Indonesian, Iranian, Iraqi, Irish, Italian, Japanese, Jordanian, Lao, Lebanese, Malaysian, Myanmarese, Nepali, New Zealander, Nigerian, Omani, Pakistani, Palestinian, Papua New Guinean, Polish, Singaporean, South African, South Korean, Sri Lankan, Sudanese, Syrian, Taiwanese, Thai, Turkish and Yemeni.
At final completion of the project, a total of 285,865,243 man hours were worked. The safety record stands proudly with an overall accident frequency rate (AFR) of 0.83 against the set target key performance indicator of less than 1 for the project.
Material used
A total of 2,580,000 m3 of concrete and 475,000 tons of rebar were used on the Red and Green lines.
