Riyadh tenders King Salman International airport runway
6 May 2025

King Salman International Airport Development Company (KSIADC), backed by Saudi Arabia’s Public Investment Fund, has issued a tender for a design-and-build contract to develop the fourth runway at King Salman International airport (KSIA) in Riyadh.
The tender was floated on 17 April. The bid submission deadline is 15 May.
Earlier in May, MEED exclusively reported that KSIADC had given firms until 12 May to submit bids for a design-and-build contract to develop the third runway at KSIA.
It is understood that the third and fourth runways will add to the two existing runways at Riyadh’s King Khalid International airport, which will eventually become part of KSIA.
KSIADC prequalified firms in September for the main engineering, procurement and construction packages; early and enabling works; specialist systems and integration; specialist systems, materials and equipment; engineering and design; professional services; health, safety, security, environment and wellbeing services; modular installation and prefabrication; local content; and environmental, social and governance and other services.
The entire scheme is divided into eight assets. These are:
- Iconic Terminal
- Terminal 6
- Private aviation terminal
- Central runway and temporary apron
- Hangars
- Landside transport
- Cargo buildings
- Real estate
In August last year, KSIADC confirmed it had signed up several architectural and design firms for the various elements of the project.
UK-based Foster+Partners will design the airport’s masterplan, including the terminals, six runways and a multi-asset real estate area.
US-based engineering firm Jacobs will provide specialist consultancy services for the masterplan and the design of the new runways.
UK-based engineering firm Mace was appointed to carry out the delivery partner role on the project, and the airspace design consultancy contract was awarded to local firm Nera.
Project scale
The project covers an area of about 57 square kilometres (sq km), allowing for six parallel runways, and will include the existing terminals at King Khalid International airport. It will also include 12 sq km of airport support facilities, residential and recreational facilities, retail outlets and other logistics real estate.
If the project is completed on time in 2030, it will become the world’s largest operating airport in terms of passenger capacity, according to GlobalData.
The airport aims to accommodate up to 120 million passengers by 2030 and 185 million by 2050. The goal for cargo is to process 3.5 million tonnes a year by 2050.
Saudi Arabia plans to invest $100bn in its aviation sector. Riyadh’s Saudi Aviation Strategy, announced by the General Authority of Civil Aviation (Gaca), aims to triple Saudi Arabia’s annual passenger traffic to 330 million travellers by 2030.
It also aims to increase air cargo traffic to 4.5 million tonnes and raise the country’s total air connections to more than 250 destinations.

Opec+ approves fourth consecutive oil output quota hike8 June 2026
The Opec+ alliance of oil producers has agreed a fourth increase in its oil output targets in as many months, even though the conflict involving Iran, the US and Israel is still preventing several members from pumping more crude.
The war has disrupted oil flows via the Strait of Hormuz, creating a severe supply crisis. Key Opec+ members, including Saudi Arabia, have been unable to supply customers in full since the end of February. The crisis for Opec+ deepened when the UAE left Opec after almost 60 years of membership.
Seven core members of Opec+ – which comprises Opec countries and a group of non-Opec states led by Russia – raised their output quotas from April to June by almost 600,000 barrels a day (b/d).
In practice, however, the group’s production has fallen sharply due to export cuts by Gulf members, averaging 33.19 million b/d in April compared with 42.77 million b/d in February, according to Opec figures.
At the latest meeting of Opec+ oil ministers on 7 June, the seven members agreed to increase targets by 188,000 b/d from July, Opec said in a statement. This matches the June hike, which was adjusted down from monthly increases of 206,000 b/d in April and May to take account of the UAE’s exit.
Iraq’s oil output quota will rise by 26,000 b/d from July under the agreement, an oil ministry spokesperson told Iraq’s state news agency.
On 5 June, oil prices fell to about $93 a barrel as traders gained confidence that renewed conflict between the US and Iran was becoming less likely. Prices were close to $72 before the war began on 28 February.
Brent crude rose sharply at the start of this week after Iran launched ballistic missiles at Israel on the night of 7 June, heightening fears that US-Iran peace talks might once again collapse. Israel has since retaliated with strikes in western and central Iran, despite calls from US President Donald Trump not to respond to the Iranian missiles.
Brent crude jumped by around 4.5% early on 8 June and was trading at $97.52 a barrel as of 11am GST.
The seven key Opec+ members are increasing production as part of the gradual unwinding of a 1.65 million b/d production cut agreed in 2023 by the coalition, which at the time included the UAE.
From July, the seven have about 567,000 b/d of the original cut left to return to the market – taking into account the UAE’s exit from 1 May – according to Reuters calculations.
That would imply the remainder of the cut will be unwound by the end of September if Opec+ maintains monthly hikes of about 188,000 b/d in August and September.
The seven of the 21 Opec+ members who met on 7 June were Saudi Arabia, Iraq, Kuwait, Algeria, Kazakhstan, Russia and Oman. In recent years, only these seven – plus the UAE when it was a member– have been involved in the group’s output-policy decisions.
In a separate meeting on Sunday attended by all Opec+ members, ministers made no change to the group-wide output policy in place until the end of 2026, Opec+ said in another statement.
Opec+ is also reviewing members’ oil production capacity to use as a reference for 2027 production baselines, from which quotas are set. On Sunday, the group reaffirmed the importance of completing the assessment, the statement said.

Deme wins dredging work for Tunisian ports8 June 2026
The Office de la Marine Marchande et des Ports (OMMP) has awarded Belgium’s Deme a contract to carry out dredging and marine works at three ports in Tunisia.
The project covers works at Sousse, Menzel Bourguiba/Bizerte and Rades/La Goulette. Deme will first construct containment dykes at the ports of Menzel Bourguiba and Sousse. The two ports are located more than 200 kilometres apart, which the contractor says will require careful planning, coordination and optimised logistics.
The second phase involves extensive dredging works at all three locations, for which Deme will deploy a trailing suction hopper dredger.
The project will use three distinct approaches to sustainably and efficiently manage dredged material, tailored to the characteristics of each location.
In Sousse and Menzel Bourguiba, the material will be reused for land reclamation. In Bizerte, a combined approach will be adopted, with part of the material used for reclamation at Menzel Bourguiba and the remainder disposed of offshore. In Rades and La Goulette, all dredged material will be pumped ashore to a designated area.

Egypt firm wins South Med desalination design contract8 June 2026
Cairo-headquartered Engineering Experience Group (EEG) has won a design and engineering services contract for the planned South Med seawater reverse osmosis desalination plant in Al-Dabaa, Egypt.
The South Med project will have a production capacity of 160,000 cubic metres a day.
Located in Egypt’s Matrouh governorate on the Mediterranean coast, it is being developed for the Engineering Authority of the Armed Forces’ Water Management Department.
Local firm Elsewedy Electric Infrastructure previously announced it was the main engineering, procurement and construction contractor for the project.
In a company publication, Elsewedy indicated that project activities are expected to run from 2026 to 2028, suggesting commercial operations could begin around 2028.
As MEED understands, Elsewedy has engaged EEG to provide engineering services. The scope includes detailed design, shop drawings, as-built documentation, project coordination and 3D building information modelling services.
The company said the work will cover electrical, instrumentation and control systems, architecture, structural and steel works, mechanical, electrical and plumbing systems, wet and dry utilities, roads and landscaping.
According to company data, the desalination sector accounts for about 25% of EEG’s water projects portfolio. The company said it has completed about 72 projects in the water sector to date, including wastewater treatment, industrial wastewater treatment, water treatment and desalination schemes.

Israel strikes Iranian petrochemicals complex8 June 2026
Israel has hit Iran’s Mahshahr petrochemicals complex in the country’s Khuzestan province, according to the Israeli military and reports in Iranian news outlets.
The Israeli military said that it was targeting Karun Petrochemical Company.
In a separate statement, Mahshahr Petrochemical Special Economic Zone said that workers at the site had been evacuated.
Karun Petrochemical Company produces a range of products.
It has the nameplate capacity to produce 40,000 tonnes a year (t/y) of toluene diisocyanate (TDI) and 40,000 t/y of methylene diphenyl diisocyanate (MDI).
It also has the capacity to produce 30,000 t/y of aniline and 92,300 t/y of nitric acid (HNO3).
TDI and MDI are both used primarily as building blocks to create polyurethane products.
TDI is mostly used to make flexible polyurethane foams and MDI is usually used to create rigid foams, adhesives, sealants and elastomers.
Aniline is also used to make urethane polymers, as well as being used in the dye industry, where it is a precursor to indigo, which is used to dye jeans blue.
Nitric acid is a highly corrosive mineral acid and its main industrial use is to produce fertilisers.
The Mahshahr petrochemicals complex is one of the most important petrochemical complexes in Iran. It was previously hit by Israel in strikes in April, forcing evacuations.
On 4 April, Israeli forces targeted at least eight major petrochemical complexes in the Mahshahr region, along with critical supporting infrastructure, including power plants that supply electricity to the industrial zone.
Mahshahr accounts for approximately 28% of Iran’s petrochemicals production.
Iran’s petrochemicals industry is the country’s second-largest source of export revenue after crude oil.
The country has a nominal production capacity of about 95 million t/y of petrochemicals, although actual output prior to the latest conflict was significantly lower due to persistent shortages of electricity and natural gas.
Iran has invested tens of billions of dollars in developing its petrochemicals infrastructure, and if facilities are severely damaged, rebuilding would pose a major financial and technical challenge.

Ora awards Unec a $517m UAE construction deal8 June 2026
Egypt’s Ora Developers has awarded local contractor United Engineering Construction (Unec) a AED1.9bn ($517m) main works contract for the first phase of the Bayn mixed-use development in Ghantoot, between Dubai and Abu Dhabi.
The 31-month construction contract covers 614 residential units, including townhouses and standalone villas, across Cluster B (Y Waterway), Cluster C (Y Lagoon) and Cluster D (Y Lagoon 2). The scope also includes associated infrastructure and landscaping works.
In a statement, Ora said mobilisation started immediately, with construction commencing on 1 June. The programme includes interim milestones for each cluster.
In December last year, NMDC Group won a AED142m contract to execute enabling works for the Bayn masterplan.
UK-based firm Mace has been appointed to lead the overall project management. Canadian firm WSP will serve as the masterplan, infrastructure, landscape and water bodies design consultant.
US-based Aecom will provide construction supervision services. Hong Kong’s 10 Design is the project’s architectural concept design consultant. Local firm Dewan Architects & Engineers is the project’s design consultant and architect of record. The UK’s Currie & Brown is the cost consultant.
MEED reported in April that Ora Developers signed a land acquisition agreement with Abu Dhabi-based developer Modon Holding to acquire an additional 4.8 million square metres (sq m) of land in Ghantoot. The acquisition will increase the Bayn masterplan from 4.8 million sq m to 9.6 million sq m.
Ora added that total investment in the masterplan is expected to reach AED30bn on completion.
