Saudi Aramco has received revised offers from bidders for the contracts to construct 11 stadiums across Saudi Arabia.

The state oil major received the offers on 15 December. The stadiums are one of the largest building programmes in the region and with estimated costs of $500m for each stadium, the total cost could exceed $5bn.

Awards for the fast-tracked project are expected by the end of December. Aramco had planned to appoint contractors in November, but it is understood the scale and complexity of the scheme, together with updates to the volume of work required, have delayed the signing of deals.

Nine groups were invited to bid. They are:

The stadiums will be located in Medina, Al-Qassim, the Eastern Province, Asir, Tabuk, Hail, the Northern Borders, Jizan, Najran, Baha and Al-Jouf.

Aramco issued a select list for each stadium, with a maximum of two contracts awarded to each consortium. The stadiums are to be built simultaneously and are scheduled for completion in June 2016.

MEED recently reported that Aramco had appointed a team of firms to project manage the development and construction of the 11 stadiums.

The project management firms that have been appointed are:

The project managers will work with US-based CH2M Hill and UK-based EC Harris, which have been appointed as programme managers.
