Construction Dewatering Projects

Please find a short synopsis of our UAE and GCC experience below:

Main activities and responsibilities:

Advanced Groundwater Modelling Solutions has designed and managed dewatering projects for over 500 sites throughout the Middle East, including the United Arab Emirates, the Kingdom of Saudi Arabia, Bahrain, Qatar, Oman, Libya, and Lebanon.

Our models were utilized to evaluate the construction dewatering requirements for the project and to produce optimal and cost-effective solutions for our clients.

Our main scope of work was:

To provide conceptual and numerical groundwater models, as well as dewatering system designs.
Perform soil settlement analysis and estimate the effects of groundwater depressurisation on shoring structures (diaphragm, secant, contiguous, sheet pile, H-beam walls, etc.) with respect to site design, excavation levels, and construction schedule.
Supervise and coordinate the work of technical and other teams, including operations, workshop, logistics, sales, projects and other departments within the dewatering division.
To recognise system deficiencies and implement effective solutions.
To create technical reports, write proposals and negotiate contracts with existing and potential clients.
To build relationships and serve as a liaison between the company and clients, consultants, and other stakeholders.
To provide project management and deliver projects within the budget and schedule.
To deliver technical presentations to clients.

Specific Projects and Tasks:

Nakheel Tall Tower, Dubai, UAE: (Client: Nakheel)

Designed by Woods Bagot for Dubai, the Nakheel Tower was planned to be the world’s tallest skyscraper. The towering spire was supposed to stand over a kilometre tall, measuring 1,400 meters (4,593 ft), which would have been higher than the Burj Khalifa. The project was part of a large 270-hectare mixed-use development called Nakheel Harbour. Our role in this project was to design a dewatering system, supervise its on-site installation, write weekly and monthly reports, liaise with the client, and manage all related dewatering activities.

Abu Dhabi Airport Expansion, Abu Dhabi, UAE: (Client: Abu Dhabi Airports Company (ADAC))

The construction of the 700,000 m² terminal building and four additional runways was one of the world-class infrastructure projects undertaken in the capital at the time. The overall project value was approximately AED 10.8 billion, making it the largest in the Emirate of Abu Dhabi. Our role in this project was to design a dewatering system, negotiate the contract, manage all site-related activities, and ensure that dewatering activities were conducted according to schedule and within budget. The dewatering system comprised more than 100 dewatering wells, and AGWMS performed various groundwater modelling tasks to meet all the project-specific requirements, which involved drawdown estimation, depressurisation analyses and recovery analyses.

Palm Jumeirah Vehicular Tunnel, Dubai, UAE: (Client: Parsons)

The Palm Jumeirah is a man-made island about 5 km in diameter, and it is one of the world’s most challenging places in terms of construction dewatering. We developed site-specific models and designed dewatering systems for various development projects on the island. One of the more noteworthy is a dewatering design for a 1.4-km-long subsea vehicular tunnel that connects the spine of the island to the outer crescent. To build the project under dry conditions, a 2.4-km-long sheet-piled cofferdam wall, up to 400 m wide, was constructed, covering a total area of 300,000 m². The construction sequence involved dredging, installation of cofferdam walls, and dewatering inside the cofferdam. Sheet piles measuring 30 meters were installed to prevent seepage into the cofferdam. More than 4.3 million m³ of seawater were discharged from the cofferdam in 45 days using high-capacity pumps.

Sheikh Khalifa Bin Zayed Stadium, Abu Dhabi, UAE: (Client: Mubadala Development)

SKBZ Stadium was one of the most prominent projects at the time, with an overall project value of DHS 5 billion (approximately US$1.36 billion). The stadium was planned to be larger than Abu Dhabi's largest stadium, Zayed Sports City, with a capacity exceeding 50,000. Our role was to design and manage a dewatering system comprising more than 200 dewatering wells, from start to finish. For this particular project, a regional groundwater model had to be developed, and an extensive monitoring system had to be implemented.

MASDAR, Abu Dhabi, UAE: (Client: Abu Dhabi Future Energy Company)

A 6 km² development envelope at MASDAR required dewatering system design and operation for the Office Building (targeted as the headquarters for the Abu Dhabi Future Energy Company and its various project units requiring office space, a high-end business centre, as well as private office space for other selected companies and organisations), university research facilities, commercial office space, technology park, research labs, testing facilities, residential and community facilities and sports facilities. Our groundwater management strategy and design contributed to our winning this project, which was one of the most prestigious in the UAE at the time.

Muscat International Airport expansion, Muscat, Oman: (Client: OAMC)

The Muscat International Airport expansion was planned to ultimately boost the airport’s capacity to 24, 36 and 48 million passengers per annum. The project comprised runways, approach roads, terminals, baggage handling systems, control towers and all the other supporting infrastructure needed in a modern airport. Our role was to develop a regional groundwater model and design a dewatering system in accordance with the project's technical requirements.

King Abdulaziz International Airport expansion, Jeddah, Kingdom of Saudi Arabia: (Client: KAIA)

The King Abdulaziz International Airport expansion project was a multibillion-dollar project. It comprised the construction of a Terminal Complex, Air Traffic Control Tower, and Supporting Facilities, as well as Aprons, Taxiways, Roads, Tunnels, Bridges, Load Centres, and Infrastructure, including a Transportation Centre and its Supporting Facilities. The KSA is well known for being a challenging location for construction dewatering due to its complex geology and proximity to open water bodies. Dewatering for the project was executed using a combination of dewatering wells, well points, and sumps, with cut-off walls positioned at strategic locations based on groundwater modelling recommendations.
