Road network (four-five lanes) including street lighting, signage, signals and landscaping.
Major quantities:
Concrete: 120,000 m³
Asphalt: 200,000 tons
Subbase: 110,000 tons
Excavation: 350,000 m³
Storm Drainage: 12,000 m
Water Works: 9,000 m
Extra HV: 11,000 m

Challenges
This was a very crucial project located on a busy road junction that links the town center to the new international airport highway, and also links a major city artery (the C Ring Road) to the Corniche sea front. The works had to be executed under a very tight program without disrupting live public traffic. This required tedious multiple day and night shifts. The extent of underground services resulted in many conflicts that had to be resolved within the project time frame. Some major interface issues were also encountered with neighboring contractors, especially those related to utility networks.
