Metro Expert Witness
Independent Metro Expert Witness services for metro, light rail and urban transit systems across the UAE and Middle East.
Urban rail construction combines deep tunnelling, complex station engineering and dense city-centre logistics — a combination that makes metro projects among the most technically and contractually complex infrastructure programmes in the UAE. With Dubai currently delivering its largest metro expansion since the network's 2009 launch, demand for specialist expert witness input in this sector is rising.
The Dubai Metro Blue Line
The Dh20.5 billion (US$5.6 billion) Blue Line, approved in November 2023 and under construction since June 2025, will add 30km and 14 stations to the Dubai Metro network, including a dedicated metro bridge over Dubai Creek and what is planned to be the world's tallest metro station at Dubai Creek Harbour. Delivered by a Turkish-Chinese consortium of MAPA, Limak and CRRC, the project reached roughly 20% completion in mid-2026, targeting 30% by year end, with more than 10,000 workers and 500 engineers deployed across twelve active sites and over 4.6 million work hours logged.
The project's first tunnel boring machine was launched in May 2026 by Sheikh Mohammed bin Rashid Al Maktoum, driving a 15.5km underground corridor through challenging creek-side geology, with the first phase of tunnelling completed in July 2026. RTA has also established two dedicated ready-mix concrete batching plants and precast production facilities at Al Ruwayyah 3 and International City — an innovative delivery model intended to tighten quality control and reduce construction timelines. The line is scheduled to open on 9 September 2029, connecting nine districts previously without metro access, including Dubai Silicon Oasis and International City, and is expected to serve up to one million residents.
Where Metro Disputes Arise
- Tunnelling and TBM performance disputes, including ground condition claims, settlement risk, and delay caused by unexpected geotechnical conditions beneath dense urban areas.
- Interface delay claims between civil, systems (signalling, rolling stock) and station-fit-out contractors on a fast-track, multi-package delivery model.
- Quantum disputes over precast and ready-mix supply chain arrangements where the client controls concrete production directly.
- Structural claims relating to elevated viaduct sections, creek-crossing bridge structures and underground interchange stations.
Our Metro Sector Capability
Our experts bring tunnelling, structural and quantum expertise specific to urban rail delivery, applying FIDIC and bespoke rail EPC contract analysis together with SCL Protocol delay methodology. We prepare CIArb Protocol and IBA Rules-compliant reports for DIFC Courts, DIAC and ADCCAC.

Frequently Asked Questions
- What core competencies does a Metro Expert Witness provide for GCC rail disputes?
- A Metro Expert Witness provides essential technical and commercial analysis for complex urban transit disputes. Within the GCC context, our experts scrutinise tunnelling methodology, station-box construction, and intricate systems integration. We deliver authoritative testimony regarding quantum and delay, ensuring that findings align with the SCL Delay and Disruption Protocol. Our reports provide the evidentiary rigour necessary for high-stakes arbitrations under DIAC or arbitrateAD rules, addressing the unique challenges of Middle Eastern mega-projects.
- How do your experts handle interface management disputes between civil and systems contractors?
- We address interface disputes by meticulously analysing project records to identify where coordination failures occurred. On metro projects in the UAE and Saudi Arabia, conflicts often arise at the juncture of civil works and rail systems. Our Metro Expert Witness specialists evaluate the responsibility for delays against the contract's interface milestones, often referencing FIDIC Gold or Silver Book standards to determine liability and the resulting financial impact on the programme.
- Why is independent expert testimony critical for metro-related arbitration in the UAE?
- Independence ensures that the tribunal receives an unbiased technical perspective on complex rail engineering issues. In the UAE, where arbitration centres like ADGM or DIAC demand high evidential standards, an independent Metro Expert Witness provides the necessary credibility. We maintain strict impartiality when assessing defects or disruption, helping legal teams and contractors navigate the technical nuances of light rail systems while adhering to RICS professional statements on expert witness conduct.
- Can you provide forensic delay analysis for metro projects under the SCL Protocol?
- Yes, our experts are highly proficient in forensic delay analysis specifically tailored for the rail sector. Recognising the linear nature of metro construction, we apply SCL Protocol methodologies to assess critical path delays caused by station excavation or signalling integration issues. By combining hand-on GCC sector experience with robust programming software, a Metro Expert Witness from our firm can accurately quantify extension of time entitlements and the associated prolongation costs for any regional dispute.
- Where does your firm provide metro expert services within the Middle East region?
- Our firm provides comprehensive services across the entire Middle East, with a primary focus on the UAE, Qatar, and the Kingdom of Saudi Arabia. We have extensive experience supporting clients involved in the Riyadh Metro, Doha Metro, and Dubai's transit expansions. Our experts are mobile and available to conduct site inspections and attend hearings in all major GCC jurisdictions, ensuring local regulatory compliance and familiarity with regional construction law and practices.
- When should a contractor involve a Metro Expert Witness in a formal dispute?
- Early involvement is highly recommended once a dispute over quantum, delay, or defects becomes apparent. Engaging a Metro Expert Witness during the pre-action phase allows for a preliminary assessment of the strength of the claim. This proactive approach is vital in the GCC, where early strategic alignment with FIDIC claims procedures can facilitate a more favourable outcome in subsequent adjudication or litigation, saving significant time and legal costs during the formal arbitration process.
- If technical defects are discovered in systems integration, how is the evidence assessed?
- We conduct a thorough forensic investigation into the technical evidence, testing data, and commissioning records. If defects are identified in systems integration or signalling, our experts analyse whether the works met the employer's requirements and international safety standards. The Metro Expert Witness then quantifies the cost of remedial works and the impact on the overall project timeline, providing a well-reasoned opinion suitable for submission to the DIFC or ADGM courts.
