Risk Assessment for Large-Scale Engineering Projects in Dubai

The Risk Management Process

The international standard ISO 31000 describes risk as the effect of uncertainty on objectives and sets out a process that works well for construction. Applied to a building project, it runs as a continuous loop:

•         Set the context and criteria. Define the project's objectives for cost, time, quality, safety and reputation, and agree how likelihood and impact will be scored, so every risk is judged on the same scale.

•         Identify risks. Workshops with the client, consultants, cost managers and, where appointed, the contractor capture what could happen, why and with what consequences.

•         Analyse risks. Each risk is rated for likelihood and impact, and larger projects often quantify cost and time effects.

•         Evaluate risks. Ratings are compared with the agreed criteria to decide which risks need action first.

•         Treat risks. For each priority risk, the team chooses to avoid, reduce, transfer or accept it, and assigns an owner and a deadline.

•         Monitor, review and report. The register is reviewed regularly, new risks are added, and closed risks are recorded.

Communication runs through every step. A risk known to one engineer and invisible to the client or contractor is still an unmanaged risk.

The four treatment options work together in practice:

•         Avoid by changing the design or scope, for example relocating a basement away from high groundwater.

•         Reduce through further investigation, redesign, testing or closer supervision.

•         Transfer through contracts, specialist subcontracts or insurance.

•         Accept with a contingency in cost and programme where the residual risk is tolerable.

Risk management sits within the wider project controls. Merka's article on running mega-projects in the UAE explains how risk, programme and cost are managed together.

Ground and Site Risks

Ground conditions are among the most expensive risks on any Dubai project, because they affect foundations, basements and the programme at the very start of construction. They also carry long-term legal weight: under UAE civil law, the contractor and supervising designer remain liable for ten years for defects threatening a building's stability, including those that arise from the ground itself.

Common ground and site risks include:

•         High groundwater near the coast and creek, which drives dewatering, basement waterproofing and uplift design.

•         Aggressive chlorides and sulphates in soil and groundwater that attack buried concrete and reinforcement.

•         Variable ground, including loose sands, cemented layers and weak rock, which may differ between boreholes.

•         Cavities and voids in some rock formations, which can affect piling and foundation performance.

•         Neighbouring structures and utilities that may be affected by excavation, dewatering or vibration.

•         Existing services and obstructions on the plot that were not recorded on available drawings.

The most effective treatment is information. A soil investigation with enough boreholes, groundwater monitoring and chemical testing, carried out to recognised standards by an accredited laboratory, reduces uncertainty before design is fixed. Pile load tests early in construction confirm design assumptions.

Foundation design then responds to the findings. Merka's foundation and structural design team selects foundation types, concrete protection and basement systems that match the measured ground conditions.

Site location changes the risk profile significantly. Merka's article comparing waterfront and desert plot conditions explains how groundwater, salt and sand vary across the UAE.

Design and Technical Risks

Design risks are the easiest to control, because they sit within the project team's own hands. They are also the most common source of variations and delays when left unmanaged.

Typical design and technical risks include:

•         An incomplete or changing brief, which leads to redesign and late decisions.

•         Coordination clashes between structure, MEP and architecture discovered on site.

•         Wind and movement effects on tall or slender buildings, affecting structure, façade and occupant comfort.

•         Façade performance risks, including water ingress, thermal performance, fire compliance and fixing failures.

•         Utility capacity, where the power, water or cooling supply available to the plot falls short of the design load.

•         Complex or unusual geometry, which raises fabrication, tolerance and constructability risks.

Complex architecture needs particular care. A concept such as the Lattice Tower Hotel, wrapped in a geometric exoskeleton, depends on early coordination between architect, structural engineer and façade specialist so the lattice can be fabricated, installed and maintained as intended.

Tall buildings multiply technical risk. Merka's article on engineering tall buildings in the UAE covers wind, movement and construction sequence in detail.

Coordinated 3D models remain the most reliable way to find clashes before construction. Merka's guide to clash-free coordination with BIM explains the approach, and design stage gates with independent internal reviews catch errors before drawings are issued.

Regulatory and Approval Risks

In Dubai, the path from design to permit and from completion to occupation runs through several authorities. Each is a potential source of delay, and each can be managed.

The main regulatory risks are:

•         Jurisdiction uncertainty, where the team is unclear whether the plot falls under Dubai Municipality, a free zone authority or a master developer's regulations.

•         Authority comments and resubmissions, which can add weeks to the programme when submissions are incomplete or inconsistent.

•         Code changes during a long design period, requiring updates to fire, structural, accessibility or green building compliance.

•         Utility constraints, such as substation requirements or connection timelines for power and water.

•         Master-developer requirements, including design guidelines, NOCs and inspections on top of the authority process.

•         Completion inspections, where incomplete fire systems, documentation or snagging delay the completion certificate.

The best treatment is experience combined with early engagement. Merka's authority approvals and NOC management confirms the governing authority at the start, prepares complete, consistent submissions and tracks every comment to closure.

A realistic approvals programme is itself a risk control. Merka's article on the stages of a Dubai permit submission sets out the sequence and typical requirements.

Green building compliance is now part of every permit, and gaps found late can force redesign. The guide to Al Sa'fat requirements for engineers explains what must be designed in from concept stage.

Commercial, Procurement and Contractual Risks

Many of the largest financial risks on a project are commercial. They depend on markets, supply chains and the contracts that allocate responsibility.

Key commercial risks include:

•         Price escalation in steel, cement, aluminium, copper and other commodities between estimate and procurement.

•         Currency exposure on imported equipment and façade systems priced in currencies other than the dirham.

•         Long-lead procurement of lifts, façades, chillers, switchgear and specialist finishes, which can set the critical path.

•         Contractor capacity, including financial strength, resources and performance on similar projects.

•         Unclear scope or interfaces between packages, leading to gaps, overlaps and claims.

•         Contract terms that allocate risks to parties least able to manage them, which tends to increase prices and disputes.

Clear tender documents are the first defence against scope and interface risk. Merka's tender packages and bid evaluation define scope precisely and compare bids on a like-for-like basis, including each contractor's qualifications and exclusions.

Early procurement of long-lead items and cost checks at every design stage protect the budget. Merka's article on capturing savings early through value engineering explains how cost risk is reduced before tender.

Contract forms such as FIDIC operate within UAE civil law, whose mandatory provisions override conflicting terms, so specialist legal advice on the contract should form part of every large project's risk treatment.

Construction, Safety and Climate Risks

Once work starts on site, the risk profile shifts toward safety, productivity and quality, with the climate influencing all three.

Safety risks. Work at height, lifting operations, deep excavations, temporary works and hot works carry the highest potential for serious harm. Treatments include method statements, permits to work, competent supervision, temporary works design checks and daily safety briefings.

Heat and climate. Summer heat creates heat stress risks for workers, limits outdoor working hours through the annual midday work break and affects concrete placement and curing. Night pours, shaded rest areas, hydration programmes and adjusted shift patterns are standard treatments. High winds and dust storms can stop crane operations, and intense rainfall, though infrequent, can flood excavations and basements.

Productivity and logistics. Constrained urban plots, limited laydown space, traffic restrictions and multiple trades working in the same area all slow progress. Detailed logistics planning and look-ahead programmes reduce congestion.

Quality risks. Defective work discovered late is costly to correct. Inspection and test plans, hold points and material testing catch problems early, and Merka's guide to quality assurance and control on UAE sites describes how those systems work.

Independent supervision is one of the strongest controls on site risk. Merka's site supervision engineers monitor workmanship, review method statements and raise issues before they become costly.

Water-related risks deserve specific planning, from dewatering during excavation to stormwater protection once the building is complete. Merka's article on drainage, stormwater and groundwater engineering covers those measures.

Risk Registers, Tools and Review Cadence

A risk assessment is only useful if it is recorded clearly, owned by named people and reviewed often enough to stay current.

The risk register. Each entry should include:

•         A clear description of cause, event and consequence, specific enough to act on.

•         The risk category, such as ground, design, approval, commercial or construction.

•         Likelihood and impact scores before treatment, using the project's agreed scale.

•         The treatment actions, with an owner and a target date for each.

•         The residual score expected after treatment.

•         Status and trend, showing whether the risk is growing, stable or closing.

Scoring. A five-by-five likelihood and impact matrix is the most common approach and gives a quick, visual way to rank risks. On large projects, quantitative analysis such as Monte Carlo simulation of cost and programme helps set realistic contingencies and completion dates.

Contingency. Cost and time contingencies should be linked to the residual risks in the register, drawn down through a controlled process and reported alongside the cost plan.

Review cadence. High-level risk workshops at every stage gate, monthly register reviews during design and construction, and immediate updates when new risks emerge keep the register relevant. Early warning procedures in the contract encourage all parties to raise problems as soon as they are foreseen.

Lessons learned. At completion, reviewing which risks occurred, which treatments worked and which risks were missed improves the next project's assessment.

Frequently Asked Questions

What is risk assessment in engineering projects? It is the process of identifying what could affect a project's cost, time, quality or safety, analysing how likely and serious each risk is, and deciding how to treat it.

What are the biggest risks on construction projects in Dubai? Common major risks include ground and groundwater conditions, design changes and coordination gaps, authority approval delays, long-lead procurement and price escalation, and heat-related safety and productivity issues.

What standard is used for risk management? ISO 31000 is the most widely used international standard, providing principles, a framework and a process for identifying, assessing, treating and monitoring risk.

What should a risk register include? A clear description of each risk, its category, likelihood and impact scores, treatment actions, owners, target dates, residual score and current status.

When should risk assessment start on a project? At feasibility, before the plot or design is committed. Early assessment allows risks to be avoided through design choices, which is far cheaper than managing them during construction.

How often should the risk register be reviewed? At every stage gate and at least monthly during design and construction, with immediate updates whenever a new risk appears or an existing one changes.
