Drilling starts for new Durrat Road |~|59 Site Body.jpg|~||~|Two Atlas Copco air compressors — including the country’s first and recently delivered XAMS 376 — are providing essential air power for two rigs on a new 38 km highway linking the proposed new resort city of Durrat Al Bahrain (meaning Pearl of Bahrain). The new resort will be located on the south-east coast of Bahrain, some 25 km from Manama. When completed, it is expected to be at least 30% larger than the capital and is likely to become Bahrain’s largest resort city. Designed by W.S. Atkins, the resort will comprise 13 different islands with over 2000 villas, luxury hotels, shopping centres, marinas and an 18-hole golf course. It will include a 600-bed, five-star hotel and a deepwater marina capable of berthing up to 400 boats. One highlight of the design is an arc of six atolls — ring-shaped coral reefs enclosing lagoons with 1.5 km of beach/atoll. Each atoll will be an independent community with 172 villas, each boasting its own beach or mooring. The atolls will be linked to the mainland via a bridge running through the ‘Pearl’ islands. Work has already begun on the new highway linking the resort city with the island’s capital, Manama, and the Askera district close to the Bahrain Aluminium Smelter (Alba). The contract has been awarded by the government of Bahrain Roads Directorate to local contractor Cybarco, for the construction of the 38 km highway. Sub-contractor Bramco, a specialist contractor in rock drilling, underwater and controlled blasting, civil excavations, quarry operations and suppliers of armour rock, is responsible for the earth works and sub-grades. Two Atlas Copco air compressors, along with the country’s first XAMS 376 — one of two units recently delivered to Bramco by local distributor Gulf Equipment and Technology (GET) — as well as an XAMS 355 are providing essential air power for rock drills. The new XAMS 376 features an electronically-controlled Mercedes 6 cylinder diesel engine, offering easy operation and monitoring with a combination of analogue gauges and digital readouts. Comprehensive and accurate data on the operating status can be simply obtained through use of scroll buttons. The digital panel also displays important warning and shutdown messages to alert the operator of any abnormal operating conditions. It also provides a free air delivery (fad) of 387 l/s at bar 8.6. The Atlas Copco XAMS 355 ensures a free air delivery of 345 l/s at bar 8.6. Two drill rigs are drilling 2 cm diameter holes up to an average 1.5 m deep in the hard limestone, allowing the contractor to blast a route through the barren desert area at the northern end of the new highway. Each hole takes between 10 and 15 minutes. Drilling 60-70 holes/blast, Bramco is drilling between 540 - 600 holes a week along a 4 km section of the highway. Bramco’s 18 month contract calls for more than 250 000 m³ of rock to be drilled, blasted and excavated. In addition to the new highway, Great Lakes Nass J.V, Great Lakes Dredging and Docks, and the Nass Group have been appointed as the dredging contractor to complete the land reclamation. A 26 month contract has been awarded with US $106 million (BHD40 million) to dredge more than 6.5 million m³.||**||
