The contract’s scope of works involves the procurement, supply and installation of a ductile iron pipeline, with a diameter varying between DN 1,600 and DN 800. The project also calls for the construction of 25 concrete water tanks, each with capacity of 10,000 cubic metres, 19 5,000-cubic-metre concrete water tanks, a 13,000-cubic-metre water break pressure tank at Al-Rayayinah and a 27,000-cubic-metre water break pressure tank at Al-Ruhaybat.

In addition, the successful contractor will be required to install electrical, communication and control systems for the scheme, provide one year’s operation and maintenance and supply spare parts for two years. The training of local personnel is a further requirement.

The project is an extension of the $4,000 million GMR first phase, completed in 1990 by the now bankrupt Dong Ah Construction Industrial Company of South Korea. The conveyance system’s water will be sourced at the $30 million Abu Ziyyan reservoir, currently under construction by Turkey’s STFA.

GMRA has also issued a tender for the project management consultancy (PMC) contract on the $1,000 million fourth phase, won by the local Al-Nahr Company (ANC)in April. Sixteen companies have been invited to bid by 9 September for the contract, with an award expected by year-end (MEED 23:4:04).
