Abstract
This paper summarizes recent developments in the design and built Al Bustan Bridge and Highway Project as part of the Qatar Expressway Programme and the lessons learned from it.
The Al Bustan South Project comprises design and construction of an expressway to the north of Doha with grade separated junctions, four-lanes dual deck to form a 1,946 m long bridge structure, including 863 on/off ramp bridges. The project includes drainage system, extra high-voltage cables, street lighting, substations, irrigation transmission pipelines, water pipelines, foul sewer, landscape, intelligent transportation, art-scaping design and construction.
The Qatar Expressway Programme is a very large road infrastructure projects that connects Doha with other cities through a set of advanced highways, roads, and flyovers. The scope is expected to deliver about 800 km of safe and efficient roads. The programme also includes the construction and development of an integrated infrastructure network equipped with state-of-the-art, reliable underground utilities, including storm water networks, electrical services, and intelligent transport systems. Al Bustan Corridor, Orbital Highway, North Road, Al Rayyan Road and Lusail Expressway part of this programme.
Design and building of highways and bridges in urban areas with very tight schedules are always big challenges to contractors as well as to the employers. The contractor must manage the busy existing traffic to provide work zones to the bridge construction works. The existing utilities and their relocation have been major issues in the structural design to accommodate the foundations. Consideration of utility relocations and traffic diversion management may change the entire concept of bridge’s design and construction. To improve life around the city and achieve aesthetic harmony in these structures, the employer had to make important provisions.
