The state-energy giant has delayed the deadline from 7 to 28 June after companies asked for more time to prepare their bids, according to a source close to the project.

The lump-sum procure-and-build contracts cover the Qatif and Hasa bulk plants in the Eastern Province; the Qasim and Sulayyil plants in the Central region; the Abha, Rabigh, Jizan and Yanbu bulk plants in the southwest; and the Duba, Jouf, Tabuk and Turaif plants in the northwest (MEED 29:5:09).

Prequalified firms include Turkey's Tekfen; Italy's Snamprogetti; South Korea's SK Engineering & Construction and ISU Engineering; Argentina's Techint; France's Technip; Spain's TR; the UK's Petrofac; Japan's JGC Corporation and Chiyoda Corporation; India's Dayim Punj Lloyd; the local MR Al-Khathlan Group; Etec Arabia; Mohammed al-Mojil Group; MS Al-Suwaidi and Nesma Group; UK-based SA Kentz; China's Sinopec; Singapore's Rotary Engineering; and Egypt's Enppi.

The firm that wins the contracts will install diesel and gasoline storage tanks, shipping pumps and conduct related civil engineering works as well as structural, piping, electrical and instrumentation works.

The work will increase the gasoline, diesel and fuel-oil storage capacities of the plants.
