TWO purpose-ordered Dynapac CC424 HF double-drum vibratory rollers have been delivered to Chinese contractor Sinohydro to begin road construction at Qatar’s prestigious Lusail new city development near Doha.

Both rollers join Sinohydro’s recently delivered CP271 pneumatic-tyred roller and an older CP142. The company also has a newly ordered extension for its Demag paver – all ordered through local distributor Oriental Trading Company.

Located just north of Doha and covering a 35 sq km site, the new city development will comprise 18 different districts. It will feature a blue water lagoon with two marinas, 25,000 residential units to house 200,000 people, high and low-rise buildings, commercial districts and mixed-use areas, retail, leisure and entertainment facilities, two golf courses, 22 schools and a hospital. It will also include an underground metro linked to the new Doha rail network.

The project has been divided into nine infrastructure packages – CP1 to CP9 – and a landscape package (CP10).
Package CP1 was awarded to Sinohydro in March 2008 with a completion date this year and includes 21.5 km of roads and highways, a bridge and five underpasses.

Its initial contract also includes infrastructure works on the marina, earthworks and site preparation.

Sinohyro has just started paving the first kilometres of its contracted 21.5 km roads and highways. The Chinese contractor has opted for a purpose-ordered fleet of Dynapac paving equipment, comprising two CC 424 HF double-drum rollers, a CP271 and CP241 pneumatic-tyred roller, and a Demag paver.

In addition, the company has rented a number of Dynapacs including a CP221 from local company Contra.

The newly delivered CC424 HF double-drum rollers feature an operating weight of 11,650 kg and drum width of 1,730 mm. Powered by a Cummins diesel engine rated at 93 kw (125hp) at 2,200 rpm, the CC424HF offers a speed range of 0 to 12 kmph.

Sinohydro, which is expected to shortly order a F141 Dynapac paver from the local dealer, is also using a fleet of LA780 Dynapac hand rollers across the Lusail development.
