Oman has become an increasingly important destination for construction investors, real estate developers, contractors, consultants, and foreign companies looking for long-term opportunities in the Gulf region. The country’s development direction, growing infrastructure needs, tourism potential, industrial zones, logistics projects, and urban expansion have created serious interest among regional and international investors.
For Iranian investors and developers, Oman is especially attractive because of its geographic proximity, relative stability, developing real estate market, and strong business relationship potential. However, entering Oman’s construction sector is not only about finding land, preparing a design, and hiring a contractor. One of the most important parts of any project is the contractor agreement.
A contractor agreement is the legal and operational backbone of a construction project. It defines what must be built, who is responsible for each part of the work, how much will be paid, when payment is due, what happens if delays occur, how quality will be checked, how variations will be approved, and how disputes will be resolved. A weak contract can turn a promising project into a long and expensive conflict.
According to Dr. Mojtaba Barghbani, many foreign investors focus too much on land price and estimated profit, while they do not spend enough time reviewing the contractor agreement. In his view, a construction contract in Oman should be treated as a risk management document, not just a price agreement. The contract must protect the investor, clarify the contractor’s obligations, and create a practical system for managing time, cost, quality, and legal responsibilities.
This article explains the most important points investors should know before signing a contractor agreement in Oman.
Advantages and Disadvantages of Buying Land and Building Property in Oman
Why Contractor Agreements Matter in Oman
A construction project involves many moving parts: land ownership, permits, design, engineering supervision, materials, labor, subcontractors, inspections, utilities, safety, payments, and final handover. The contractor agreement connects these elements into a clear framework.
Without a strong contract, the project owner may face several risks:
The contractor may delay the project without clear consequences.
The scope of work may become unclear.
The contractor may request extra payments for work that should already be included.
The quality of materials may not match the investor’s expectations.
The project may face disputes over design changes.
The owner may not have enough protection against defective works.
The handover process may become incomplete or delayed.
The investor may struggle to enforce warranties or guarantees.
In Oman, as in many civil law jurisdictions, construction contracts are not only commercial documents. They are also connected to statutory rules, professional duties, engineering responsibilities, and local administrative requirements. This means that the investor should not use a simple copied contract from another country without reviewing its suitability for Oman.
Understanding the Concept of Muqawala in Oman
In Oman, construction contracts are commonly associated with the legal concept of Muqawala. In simple terms, Muqawala refers to a contract where one party undertakes to perform work or produce something in return for payment. In the construction context, this usually means the contractor agrees to carry out construction works for the project owner.
This concept is important because it shows that a construction contract is not only a normal service agreement. It creates reciprocal obligations between the employer and the contractor. The contractor must perform the work according to the agreed scope, specifications, and professional standards. The employer must provide payment, site access, approvals, and cooperation according to the contract.
For foreign investors, understanding Muqawala helps avoid a common mistake: assuming that the contract is only about price and timeline. In reality, a contractor agreement should cover technical, legal, financial, administrative, and operational details.
Start With Proper Due Diligence Before Signing
Before signing any contractor agreement in Oman, the investor should carry out due diligence. This means checking the contractor, the project documents, the legal structure, and the practical feasibility of the work.
A contractor may make strong promises during negotiation, but promises are not enough. The investor should verify whether the contractor has the license, experience, financial ability, technical team, equipment, subcontractor network, and local knowledge required for the project.
Important due diligence questions include:
Is the contractor legally registered and licensed in Oman?
Has the contractor completed similar projects before?
Can the contractor provide references?
Does the contractor have enough financial capacity?
Who will manage the project on site?
Does the contractor understand local permit and inspection requirements?
Does the contractor have qualified engineers and supervisors?
How does the contractor manage subcontractors?
What happens if material prices change?
Does the contractor have insurance coverage?
Has the contractor been involved in previous disputes?
A contractor agreement should not be signed only because the price is low. In construction, the cheapest contractor can become the most expensive option if delays, defects, claims, and disputes appear later.
Define the Scope of Work Clearly
The scope of work is one of the most important parts of a contractor agreement. It explains exactly what the contractor must deliver. If the scope is unclear, disputes are almost guaranteed.
A strong scope of work should include:
Description of the project
Approved drawings
Technical specifications
Material standards
Structural works
Architectural finishes
Mechanical, electrical, and plumbing works
External works
Landscaping, if included
Temporary works
Site preparation
Testing and commissioning
Cleaning and handover requirements
Documentation to be delivered at completion
The investor should make sure that the scope matches the approved plans and permit conditions. If the contractor’s price is based on incomplete drawings, the investor may face many variation claims later.
Dr. Mojtaba Barghbani emphasizes that a project owner should never accept a vague sentence such as “complete construction works as agreed.” The contract must explain what “complete” actually means. Every major item should be linked to drawings, quantities, brands, standards, or measurable requirements.
Choose the Right Contract Type
Different construction projects may require different contract types. The best contract structure depends on the project size, design maturity, risk allocation, and investor’s management capacity.
Common contract structures include:
Lump-sum contract
Unit price contract
Cost-plus contract
Design and build contract
Construction management arrangement
EPC contract for larger industrial or infrastructure projects
A lump-sum contract gives the investor more cost certainty if the drawings and specifications are complete. However, if the design is incomplete, the contractor may later claim extra payments for unclear or missing items.
A unit price contract can be useful when quantities are uncertain, but it requires strong measurement control.
A design and build contract gives the contractor responsibility for both design and construction, but the employer must define performance requirements very carefully.
For foreign investors, the main question is not “Which contract type is popular?” The real question is “Which contract type best matches the project’s risk profile?”
Include a Detailed Payment Schedule
Payment disputes are common in construction projects. A good contractor agreement should clearly explain how and when the contractor will be paid.
The payment schedule should define:
Advance payment, if any
Progress payment milestones
Required documents for each payment
Consultant certification process
Retention amount
Payment deadline after approval
Deductions for defects or delays
Final payment conditions
Release of retention
Bank guarantees or performance bonds
Payments should be connected to actual progress, not only dates. For example, instead of paying a large amount after one month, the contract can link payment to completion of foundation, structural frame, blockwork, MEP rough-in, plastering, finishing, testing, and handover.
This protects the investor from paying too much before the work is completed. It also gives the contractor a clear cash flow structure.
Foreign investors should avoid informal payment arrangements. Every payment should be documented, linked to an invoice or certificate, and recorded properly.
Clarify Variation and Change Order Procedures
Changes are common in construction. The owner may request design changes. Authorities may require modifications. Site conditions may differ from expectations. Materials may become unavailable. The contractor may propose alternatives.
The problem is not the existence of changes. The problem is uncontrolled changes.
A contractor agreement in Oman should include a clear variation procedure. It should explain:
Who can request a variation
How the variation must be submitted
Whether the contractor can proceed before written approval
How cost will be calculated
How time impact will be assessed
What documents must support the claim
Who approves the change
How variations affect the completion date
The investor should never allow major changes based only on verbal approval. If a change affects cost or time, it must be recorded in writing before execution.
Uncontrolled variations are one of the most common reasons projects exceed their budget.
Define the Project Timeline and Delay Rules
Time is a critical part of construction. Delays can affect financing, sales, rental income, investor commitments, and reputation. The contractor agreement should include a clear start date, completion date, milestone dates, and delay consequences.
The contract should define:
Commencement date
Site handover date
Total project duration
Milestone schedule
Permitted causes of delay
Notice requirements for delay claims
Extension of time procedure
Liquidated damages or delay penalties
Owner-caused delay rules
Force majeure events
Suspension rights
Termination rights for major delay
A contractor should not automatically receive extra time for every problem. The contract should require timely notice and proof. If the delay is caused by the contractor’s lack of labor, poor planning, late procurement, or weak management, the contractor should be responsible. If the delay is caused by the owner, late approvals, or changes requested by the employer, the contract should address that fairly.
A balanced delay clause protects both sides and reduces future disputes.
Pay Attention to Materials and Quality Standards
Material quality is a major issue in construction contracts. If the contract only says “good quality materials,” the phrase may not be enough. The agreement should clearly define acceptable materials, brands where necessary, technical standards, samples, mockups, testing requirements, and approval procedures.
This is especially important in Oman because climate conditions can affect material performance. Heat, humidity in coastal areas, dust, sunlight, and corrosion risk may influence material selection. Poor materials can lead to cracks, waterproofing failure, façade problems, electrical issues, plumbing defects, and expensive maintenance.
The contract should state that the contractor cannot substitute approved materials without written approval. It should also require the contractor to submit samples and technical data sheets before procurement.
A proper quality clause should include:
Material specifications
Inspection rights
Testing requirements
Consultant approval
Rejection of defective materials
Replacement obligations
Workmanship standards
Protection of completed works
Defect correction procedures
Quality should be managed during construction, not only at handover.
Clarify the Role of the Consultant or Engineer
Many construction projects in Oman involve an engineering consultant who prepares designs, supervises the works, certifies payments, checks quality, and coordinates with authorities. The contractor agreement should clearly explain the consultant’s role.
The contract should state:
Who the consultant is
What authority the consultant has
Whether the consultant can approve payments
Whether the consultant can instruct variations
How site inspections will be arranged
How the consultant will certify completion
How disagreements with consultant decisions will be handled
If the consultant’s authority is unclear, the contractor and owner may later disagree about instructions, approvals, and payment certificates.
For foreign investors who are not always present in Oman, the consultant’s role becomes even more important. The consultant can act as the technical eyes of the investor, but the scope of supervision must be clear.
Manage Subcontractors Properly
Contractors often use subcontractors for specialized works such as MEP systems, aluminum, façade, waterproofing, elevators, fire systems, landscaping, interior finishes, and other trade packages. Subcontracting is normal, but it must be controlled.
The contractor agreement should define whether the contractor can appoint subcontractors freely or only with the owner’s approval. It should also state that subcontracting does not release the main contractor from responsibility.
Important subcontractor clauses include:
Approval of key subcontractors
Contractor responsibility for subcontractor work
Insurance requirements
Coordination obligations
Safety compliance
Replacement of unsuitable subcontractors
No direct payment unless agreed
Confidentiality and site conduct rules
A foreign investor should not allow the main contractor to shift blame to subcontractors. The main contractor should remain responsible for delivering the project as a whole.
Include Insurance, Bonds, and Guarantees
Construction involves risk. Accidents, property damage, worker injuries, fire, defective works, and third-party claims may occur. A contractor agreement should clearly state what insurance and guarantees are required.
Depending on the project, the contract may require:
Contractor’s all-risk insurance
Third-party liability insurance
Worker compensation or labor-related coverage
Professional indemnity insurance for designers, where applicable
Performance bond
Advance payment guarantee
Retention guarantee
Warranty bonds for specific systems
These tools do not eliminate risk, but they provide financial protection if something goes wrong.
The investor should not only ask whether the contractor has insurance. The investor should review the policy limits, exclusions, validity period, insured parties, and claim process.
Address Health, Safety, and Site Management
Construction safety is not optional. A contractor agreement should include clear safety obligations. Poor safety practices can cause injuries, shutdowns, delays, legal exposure, and reputational damage.
The contract should require the contractor to manage:
Site access control
Worker safety
Protective equipment
Scaffolding safety
Electrical safety
Fire prevention
Storage of materials
Traffic movement
Waste management
Emergency procedures
Compliance with applicable labor and safety rules
The contractor should also be responsible for keeping the site clean, organized, and secure.
For investors developing projects in residential or commercial areas, site management is especially important because construction activities can affect neighbors, roads, utilities, and public safety.
Understand Defects Liability and Long-Term Responsibility
Defects can appear during construction, at handover, or after the building is occupied. The contractor agreement should include a defects liability period during which the contractor must repair defects at its own cost.
The contract should define:
Length of defects liability period
Procedure for reporting defects
Time allowed for repair
Emergency repair rights
Owner’s right to deduct costs if contractor fails to repair
Final inspection process
Release of retention after defects period
Warranties for equipment and systems
In Oman, investors should also be aware of long-term liability concepts related to serious structural defects and building safety. This makes it even more important to select qualified contractors and consultants and to document the quality of construction.
A strong contract should not only focus on completing the building. It should also protect the owner after handover.
Include a Clear Handover Procedure
Handover is a critical stage. Many disputes happen because the owner believes the project is incomplete while the contractor demands final payment.
The contractor agreement should define what practical completion means. It should list the documents and conditions required for handover, such as:
Completion certificate
As-built drawings
Testing and commissioning reports
Operation and maintenance manuals
Warranty certificates
Authority approvals
Utility connection documents
Keys and access cards
Defect list
Cleaning and site clearance
Training for facility systems, if needed
The contract should allow the owner or consultant to prepare a snagging list. The contractor should complete the snagging items within a defined period.
Final payment should be linked to proper handover, not just physical completion.
Dispute Resolution: Courts, Arbitration, and Escalation
Even with a strong contract, disputes can still arise. The best contract is one that provides a clear path for resolving disputes without destroying the project.
A contractor agreement should define:
Governing law
Language of the contract
Negotiation process
Engineer or consultant determination, if applicable
Mediation, if agreed
Arbitration or court jurisdiction
Seat and rules of arbitration
Language of proceedings
Interim measures
Continuation of work during disputes
For international investors, arbitration may be attractive because it can provide a more specialized and neutral forum, depending on the contract structure. However, the dispute resolution clause must be drafted carefully by legal professionals.
A vague dispute clause can create a second dispute about how the first dispute should be resolved.
Be Careful With Force Majeure Clauses
Force majeure clauses became more important after global disruptions, pandemics, regional conflicts, shipping delays, and supply chain problems affected construction projects worldwide.
A force majeure clause should not be copied blindly. It should define what events qualify, what notice must be given, what relief is available, whether time is extended, whether cost compensation is available, and when termination becomes possible.
Examples may include natural disasters, war, government restrictions, major supply chain disruptions, or other events beyond the parties’ control. However, ordinary contractor mismanagement should not be treated as force majeure.
The contract should also require mitigation. If an event occurs, the affected party must take reasonable steps to reduce delay and damage.
Common Mistakes Investors Make in Contractor Agreements
Foreign investors in Oman often make avoidable mistakes when signing contractor agreements. These mistakes include:
Signing a contract based only on a price quotation
Starting work without approved drawings
Using a contract copied from another country
Ignoring permit conditions
Leaving the scope of work unclear
Not defining material specifications
Paying too much in advance
Failing to control variations
Not including delay penalties
Not checking contractor licenses and past projects
Ignoring insurance and guarantees
Allowing verbal instructions
Not planning for defects and handover
Using unclear dispute resolution clauses
Each of these mistakes can create financial loss. The solution is to treat the contractor agreement as a strategic document, not a formality.
Practical Checklist Before Signing a Contractor Agreement in Oman
Before signing, the investor should confirm the following:
The contractor is licensed and qualified.
The project drawings are complete enough for pricing.
The scope of work is detailed and measurable.
The payment schedule is linked to progress.
Variation procedures are written clearly.
The project timeline and milestones are defined.
Delay consequences are included.
Material standards are specified.
The consultant’s role is clear.
Subcontracting rules are included.
Insurance and guarantees are required.

Dr. Mojtaba Barghbani can play an important role in helping investors approach Oman’s construction market with a more strategic mindset. His guidance is especially valuable for investors who are entering Oman for the first time and may not be familiar with local construction risks.
From his perspective, the contractor agreement should be reviewed as part of the whole investment plan. It should not be separated from feasibility study, land selection, permit strategy, project financing, contractor due diligence, and exit planning.
A well-prepared contractor agreement helps answer practical questions before problems occur:
Who is responsible if the project is delayed?
Who pays for design changes?
What happens if materials are defective?
How will payments be controlled?
Who supervises the work?
What documents are needed at handover?
How will disputes be resolved?
By asking these questions early, investors can reduce uncertainty and improve the chance of project success.
