WINNER CADILLAC GCC TRANSPORT PROJECT OF THE YEAR
UAE
Dubai Metro Green Line
Entrant: Roads & Transport Authority (RTA) – Rail Agency
Project owner: RTA – Rail Agency
Project contractor: DURL Construction Consortium
Engineering consultant: Systra/Parsons
Architect: Aedas
Engineer: Atkins
Description: Dubai has expanded to almost double its size and population through rapid upward and horizontal urban development. The Dubai government, through Dubai Municipality and the RTA, developed a well-designed, comfortable metro system with Red and Green lines. An environmental impact assessment (EIA) study was carried out for the Green Line project and several mitigation measures were considered to control the environmental impact. Measurements were taken regularly to ensure that standards were adhered to in areas such as air quality, dust emissions, noise and vibration. In addition, the health and safety of the population were considered. The wellbeing of workers was monitored through regular inspection of their living quarters and work sites.
UAE
Sheikh Zayed Bridge
Entrant: Six Construct
Project owner: Emirate of Abu Dhabi, Abu Dhabi Municipality
Project contractor: Six Construct/Archirodon
Engineering consultant: High Point Rendel
Architect: Zaha Hadid Architects
Description: Sheikh Zayed Bridge, located at the northern end of the Maqta Channel, provides a third crossing to the island of Abu Dhabi. It eases traffic congestion and facilitates access to the rapidly expanding residential and commercial developments in the surrounding areas. To enhance the bridge’s appearance, the deck boxes include open outer cells that are illuminated at night. The post-tensioned concrete box girders are supported by inclined post-tensioned concrete piers, which are themselves founded on piles with a diameter of up to 1.5 metres. The spans over the channels are supported from the arch’s ribs by stainless steel pipe hangers. Zaha Hadid’s ‘Sand Dune’ design was selected to make the bridge a landmark structure.
Saudi Arabia
Northwest Leg of Riyadh Ring Road
Entrant: Shibh al-Jazira Contracting Company
Project owner: Transport Ministry
Project contractor: Shibh al-Jazira Contracting
Engineering consultant: Dar al-Handasah
Description: The northwest leg of the Riyadh Ring Road was one of the most challenging roads to construct in the kingdom. The project involved crossing three deep wadis to complete the outer ring road of Riyadh city and link it to the industrial southern area. The 13-kilometre project has three viaducts, five interchanges and two bridges. The scheme has not intruded into or split the agricultural plantations at Wadi Hanifah. A prominent feature of the ring road is the almost vertical walls that show off the striking layers, faults and cavities in the metamorphic limestone.
