The mixed-use development forms the commercial centre of the Barwa City residential development which is under construction, and consists of office and residential buildings with ground-level shops along an 8.6 kilometre-long avenue. The first phase of Hochtief’s contract involves a pre-construction agreement that will result in the contractor estimating the cost of the project. During this time it will review the design documents, decide on the method of project delivery and the time needed for procurement, installation and construction. During the second phase, Hochtief will execute the project as the main contractor. It plans to subcontract the civil, structural, architectural, facade and mechanical, electrical and plumbing works. The scheme should be completed in early 2011. Bilfinger Berger, also of Germany was awarded the QR 4,890 million ($1,310 million) contract to build the residential development in April. The three-year contract involves the construction of a residential compound with 6,000 housing units and community facilities. Cansult Maunsell, part of US-based Aecom, is the consultant. The client is Barwa Real Estate Company (MEED 4:5:07). The contract is the latest to be awarded to Hochtief in Qatar. The firm is part of the consortium that signed a memorandum of understanding for the estimated $2,000 million, 45 kilometre-long Qatar-Bahrain Causeway in early October. The other consortium members are the local Qatari Diar Real Estate Investment Company, Vinci Grand Projets, Athens-based Consolidated Contractors International Company, and Belgium’s Dredging International with the local Qatar Dredging Company (MEED 5:10:07).
