5 MISTAKES TO AVOID WHEN HIRING AN ARCHITECTURAL CONSULTANT IN OMAN

Mistake 1

Mistake 1: Hiring on Price Alone

The instinct to select the lowest-fee proposal is understandable — engineering consultancy is a significant line item in project development budgets, and cost control is a legitimate discipline. The problem is that engineering fees are not like commodity procurement where the specification is fixed and price is the only variable. The gap between a low-fee and a high-fee proposal typically reflects the difference between what will actually be delivered — the depth of calculation, the level of drawing coordination, the quality of authority submission package, and the degree of site supervision provided.

A consultant who wins on a 40 percent lower fee than competitors has to recover that cost somewhere. The most common place is in reduced drawing coordination time, which increases the probability of errors and authority rejection. The second most common place is in reduced site visits — the design is produced but never properly checked during installation, and the gap between what was drawn and what was built only becomes apparent at completion, or worse, during operation. When a low-fee submission leads to a permit rejection with an eight-week resubmission delay, or a site defect list that requires the contractor to redo finished elements, the apparent savings evaporate entirely — and the client often ends up paying twice.

The right question to ask is not "what is the fee?" but "what does the fee include?" A detailed scope of services document that clearly states the number of drawings, the extent of calculations, the number of authority submissions included, and the site visit schedule allows genuine comparison between proposals on a like-for-like basis. A consultant who cannot or will not provide this level of scope clarity is giving you a reason to look elsewhere before you've spent a single Rial.

Mistake 2: Ignoring OES Licensing

Oman's Engineering Society (OES) registration is not an optional professional credential — it is a legal requirement for any engineer who signs and stamps drawings submitted to Oman's authorities. Every set of architectural, structural, and MEP drawings submitted to Muscat Municipality, Civil Defence, or any other regulatory authority in the Sultanate must bear the stamp and signature of a currently registered OES member in the relevant engineering discipline. A drawing signed by an unregistered engineer — or by a registered engineer signing outside their declared discipline — will be administratively rejected without technical review. The clock stops, the programme takes a hit, and the client pays for a resubmission process that should never have been necessary.

The OES licensing check is one of the simplest due diligence steps available to a developer — ask any prospective consultant to provide their OES registration certificate, confirm it is current (registrations must be renewed annually), and verify that the disciplines listed on the certificate match the scope of work you are procuring. If a firm proposes to provide structural engineering services under an architect's OES stamp, that is a compliance problem you will discover at the worst possible moment — when authority rejection sends your project timeline backwards by months.

Beyond OES registration, check that the consultancy firm itself holds a valid Commercial Registration in Oman that includes engineering consultancy within its declared business activities. Individuals operating without proper company registration may be able to produce drawings but cannot legally represent you in authority submissions or sign contracts with the municipalities on your behalf.

Mistake 3

Mistake 3: Skipping Scope Definition

A verbal agreement or a one-paragraph letter of engagement is not a scope of services — it is an invitation to a dispute. In Oman's construction market, some of the most contentious client-consultant relationships arise not from poor design quality but from fundamentally different understandings of what was included in the fee. The client believes structural calculations are included; the consultant considers them an additional service. The client assumes the authority submission fees are covered; the consultant invoices them separately. The client expects site visits at every critical construction stage; the consultant's team appears only for the foundation inspection.

A properly defined scope of services document resolves all of these ambiguities before work begins. It should specify: the design stages to be completed (concept, schematic, design development, construction documents, as-built); the disciplines covered (architecture, structure, MEP); the deliverables at each stage (drawing list, calculation report, specification); the number of authority submissions included and what happens in the event of a resubmission requirement; the site supervision scope (hold points, frequency of visits, report requirements); and any exclusions that the client needs to procure separately, such as geotechnical investigations, traffic impact assessments, or specialist facade engineering.

Mistake 4

Mistake 4: Choosing a Single-Discipline Firm

Architectural design, structural engineering, and MEP engineering are distinct professional disciplines that require specialist knowledge and OES registration in each field. Yet they are not independent — the decisions made in each discipline directly constrain and enable what the others can achieve. When these disciplines are procured from separate firms without a single party holding overall design coordination responsibility, the coordination gap that opens between them is one of the most common sources of construction problems in Oman.

The classic failure mode: the architect designs a column-free open-plan floor plate that is structurally achievable only with deep transfer beams — beams that eliminate the ceiling void depth the MEP engineer needed for duct routing. Discovered late in design development, this triggers an expensive redesign cycle. Discovered on site, it triggers a variation order and a programme delay. Discovered by the authority reviewer, it triggers a rejection and resubmission. In each case, the cost of the problem grows as it is discovered later, and the fundamental cause is the absence of anyone who was responsible for all three disciplines simultaneously and whose financial interest was aligned with their coordination.

A multidisciplinary firm — one that delivers architecture, structure, and MEP under a single fee and single professional responsibility — eliminates this coordination gap structurally. When the same management team is accountable for all three disciplines, conflicts between disciplines are resolved internally, early, and cheaply. The client receives a coordinated package rather than three sets of drawings that are technically independent of each other. This is the model First Step Engineering operates, and it is the primary reason our projects proceed through authority review and construction without the costly variation events that characterise poorly coordinated single-discipline procurements.

Mistake 5

Mistake 5: No Contract for Authority Revisions

Authority review in Oman is rarely a pass/fail binary — even well-prepared submissions may receive technical comments that require design clarification or minor revision. The question of how these responses are handled, and who bears the cost, must be established in the consultancy contract before submission, not debated after comments are received. Many lower-fee proposals implicitly include only one round of authority submission; any revision comments that require additional drawing revisions, updated calculations, or additional meetings with authority reviewers are treated as additional services billed at extra cost. For a developer who was expecting a fixed-fee service, this is a financially and contractually uncomfortable discovery.

When reviewing any engineering consultancy contract, look specifically for the provision covering authority resubmissions. A reputable firm with a strong track record of first-pass approval will typically be willing to include a defined number of revision rounds within the base fee, because their quality process means resubmissions are rare in practice. A firm that insists on billing every revision comment as an additional service is signalling, perhaps inadvertently, that it expects its submissions to generate comments — which is not the confidence-inspiring message a developer should accept.

Beyond the resubmission clause, ensure the contract clearly states liability for authority rejection caused by design error — errors in the engineer's own drawings, not changes in authority requirements. An engineer whose drawings contain a compliance error that causes rejection should bear the cost of correcting those drawings as a professional obligation, not invoice the client for the additional work required to fix a mistake.

Selection Framework

What to Look for in an Engineering Consultant

Having worked with developers across Oman's residential, commercial, and mixed-use sectors for over a decade, we have observed a consistent pattern in the characteristics that distinguish successful engineering partnerships from problematic ones. The most reliable predictor of a good outcome is not the quality of the portfolio presentation or the polish of the fee proposal — it is the clarity and confidence with which the consultant explains their process: how they coordinate across disciplines, how they manage authority submissions, how they handle design changes mid-project, and how they ensure that what is designed is what is built.

When evaluating engineering consultants for your next Oman project, conduct reference checks with previous clients on projects of similar type and scale. Ask those clients specifically about three things: whether the project was approved first time by the relevant authorities, whether construction proceeded without significant design-related variations, and whether they would use the same firm again. These three questions cut through marketing material and establish the most meaningful performance indicators available.

Verify OES registration as described above — this is non-negotiable. Confirm that the firm's engineers who will actually work on your project are the same seniority as those presented in the credentials meeting — a common issue in larger firms is that senior engineers present and junior staff deliver. Ask for a draft scope of services document before signing any fee agreement, and review it carefully against the checklist above. And if a firm cannot provide a clear, detailed answer to how they manage authority resubmissions and at whose cost, you already have the information you need to move to the next candidate.

First Step Engineering was built on the premise that Oman's developers deserve a single, accountable engineering partner that delivers all disciplines with equal competence under a single quality management system. Our ISO 9001:2015 certification, our OES-registered multidisciplinary team, and our zero-rejection authority submission record are the evidence against which that premise is tested — and the reason our clients return to us project after project.
