Search for the stages of a construction project and you will find sources confidently stating there are four, five, six or seven. They are not contradicting each other — they are answering from different chairs. A project manager, an owner, a contractor and a designer each break the same project differently, and which framework applies to you depends on which of those you are. This guide maps the main frameworks against each other, walks the seven stages a Gulf project actually passes through, and covers the approval gates that decide when one stage can end and the next begin.

What Are the Stages of a Construction Project?
The stages of a construction project are the defined phases a project moves through from the decision to build to the operation of the finished asset. Dividing the work this way lets everyone plan, manage and track progress, and it creates the gates at which a project either proceeds, changes or stops.
The most useful framing is this: a construction project is not one long construction phase. It is a chain of connected decisions and deliverables. Each stage produces something the next stage depends on, and the failures that hurt most happen at the joins rather than inside the stages.
Why Sources Disagree on the Stages of a Construction Project
This is the question every guide on this subject skips, and it is the one that unlocks the rest.
Different frameworks for the stages of a construction project exist because different parties have different jobs. The stages are not an objective property of the building — they are a way of organising responsibility, and responsibility looks different depending on where you sit.
| Who is asking | What they need the stages to organise | Where their framework starts and stops |
|---|---|---|
| Project manager | Control of a defined piece of work | Initiation to closure — the PMBOK-style five |
| Owner | An asset held for decades | Feasibility to decommissioning — the longest view |
| Contractor | Their scope under a contract | Award to handover, with a defects period |
| Designer | Progressive resolution of a design | Brief to construction documents, plus site support |
The clearest illustration is the end of the project. A contractor’s main delivery obligations reduce after contractual handover — from their chair, the project is finished. From the owner’s asset perspective the lifecycle continues into operations, maintenance, warranty, refurbishment and eventually replacement or decommissioning. Neither view is wrong; they are answering different questions.
The Frameworks Mapped
Four frameworks for the stages of a construction project appear regularly in this region. Here is how they correspond.
| Stage in this guide | CMAA-style | PMBOK-style | RIBA Plan of Work | AIA phases |
|---|---|---|---|---|
| 1. Feasibility | Pre-design | Initiation | Stages 0–1 | Pre-design / programming |
| 2. Design | Design | Planning | Stages 2–4 | Schematic design, design development, construction documents |
| 3. Preconstruction | — | — | — | |
| 4. Tender and procurement | Procurement | — | Transition into Stage 5 | Bidding / negotiation |
| 5. Construction | Construction and monitoring | Execution and monitoring | Stage 5 | Construction administration |
| 6. Commissioning and handover | Closure | Stage 6 | — | |
| 7. Operation and maintenance | Post-construction | — | Stage 7 | — |
Working across frameworks on a multi-consultant project?
AMC Engineer delivers coordinated LOD 300–500 BIM models across Architecture, Structure, MEP, Electrical, Infrastructure and Landscape — with deliverables aligned to whichever stage framework your appointment actually uses. Free LOD 200 sample from your own drawings in 24 hours.
Stage 1 — Feasibility and Initiation
The question: should we build this at all?
- Project purpose, objectives and the business case
- Market analysis and demand assessment
- Site identification, plot data and regulatory review
- Technical, financial and environmental feasibility
- Order-of-magnitude cost estimate and return assessment
Closes with: a decision to proceed, defer or stop.
The most common failure here is committing capital on an estimate produced at a class that was never intended to support the decision. Our guide to construction cost estimation covers the estimate classes and why an early figure needs its accuracy range stated alongside it.
Stage 2 — Design
The question: what exactly are we building?
Design itself divides into sub-stages that most frameworks treat as one:
- Concept / schematic design — massing, layout, spatial organisation, the structural grid, and the first meaningful cost estimate. See our guide to schematic design.
- Design development — materials selected, systems designed, disciplines coordinated.
- Construction documents — the detail, specification and permitting documentation.
Closes with: a coordinated, permittable design set.
Building-type specifics matter more than generic guidance suggests — our guide to commercial building design covers how cooling load, structure and floor-to-floor height interact in a Gulf building.
Stage 3 — Preconstruction and Planning
The question: how will we actually build it?
- Work breakdown structure and construction sequencing
- Baseline programme with logic, durations and the critical path
- Resource, plant and site logistics planning
- Constructability review and method statements
- Risk register and mitigation
Closes with: an accepted baseline programme and an executable plan.
This is the stage most compressed under commercial pressure and the one where compression costs most. Our guide to construction planning covers baseline schedules, scheduling methods and the regional calendar constraints that make a temperate-climate programme wrong from the day it is issued.
Stage 4 — Tender and Procurement
The question: who builds it, and at what price?
- Tender documents issued, including the bill of quantities
- Bids received, evaluated and clarified
- Award and contract execution
- Long-lead items identified and ordered
- Subcontract packages let
Closes with: a signed contract and orders placed on the critical items.
Two documents govern this stage. Our guide to the bill of quantities covers measurement standards and how the priced bill goes on to value variations and interim payments, and our guide to the bill of materials covers the order-to-site path that determines when material actually arrives.
Stage 5 — Construction
The question: is it being built as designed, on programme?
- Site mobilisation and enabling works
- Shop drawing and material submittals, and their review cycles
- Substructure, superstructure, envelope, services, finishes
- Coordination, inspection and quality control throughout
- Progress measurement, valuation and change management
Closes with: practical or substantial completion.
Two things dominate this stage in practice. The submittal cycle sits on the critical path more often than teams plan for — see our guide to shop drawings in construction. And coordination continues rather than ending at design — see our guide to BIM coordination.
Stage 6 — Commissioning and Handover
The question: does it work, and can the operator run it?
- Systems testing, balancing and commissioning
- Authority inspections and certificates
- Snagging and defect rectification
- As-built documentation and operating manuals
- Asset register, training and formal handover
Closes with: handover certificates issued and the defects liability period beginning.
Stage 7 — Operation and Maintenance
The question: how does the asset perform over its life?
This is the stage most frameworks omit, because most frameworks are written from the contractor’s or project manager’s chair. From the owner’s perspective it is by far the longest and most expensive stage.
- Planned and reactive maintenance
- Energy and performance monitoring
- Warranty management through the defects period and beyond
- Fit-out, refurbishment and change of use
- Capital replacement planning, and eventually decommissioning
Where an owner wants operational data rather than only records, our guide to digital twin technology covers what that actually requires — and why the handover model decides whether it is possible at all.
Construction Project Stages and Approval Gates in KSA and the UAE
International guides describe the stages of a construction project as though the only thing ending one is the team deciding it is done. In this region, several stages end when an authority says so — and those gates deserve their own place in the programme.
Saudi Arabia
- Land use and plot regulations — permitted use, coverage, setbacks, height and parking, set at municipal level and differing between cities. A Stage 1 input, not a Stage 5 discovery.
- Municipal (Amanah) permit review, with submission requirements and processes that differ by municipality.
- Saudi Building Code compliance, with the 2024 edition having become mandatory from 30 June 2025.
- Civil Defence review of fire strategy and fire-related scope.
- Occupancy certificate. A decision in October 2024 amended the SBC Implementation Law to make the occupancy certificate a prerequisite for full activation of electrical current — which turns a documentation gate into a functional one.
United Arab Emirates
- Plot data and affection plan — permitted use, built-up area, height and setbacks. Everything begins here.
- Master developer design review on master-planned plots, operating alongside statutory approval rather than instead of it, and on its own meeting cadence.
- Municipal review by Dubai Municipality or the Abu Dhabi Department of Municipalities and Transport. Dubai Municipality introduced BIM model submission for new building permits in IFC format following a circular issued in October 2023.
- Civil Defence review of fire-related scope under the UAE Fire and Life Safety Code.
- Green building requirements under Al Sa’fat in Dubai or Estidama in Abu Dhabi, with design-stage obligations.
- Utility approvals for connection and energisation.
What this means for the programme
- Approval durations are activities, not overheads. They belong in the baseline with predecessors, not as an assumed instant.
- They are sequential. Authority review follows consultant review, so a package that only just cleared internal review has no float when the authority responds.
- They are layered. A single project may face master developer, municipal, Civil Defence, green building and utility gates — each with its own submission requirements.
Need deliverables that clear the gate, not just the internal review?
We structure federated models for authority submission — classification, property sets, naming and coordinate systems — and coordinate all disciplines before the export is ever tested.
What BIM Delivers at Each Stage of a Construction Project
BIM is the thread that runs through every stage of a construction project, and its value increases sharply when information requirements are defined consistently across them rather than reinvented at each handover.
| Stage | What BIM contributes | Typical LOD |
|---|---|---|
| 1. Feasibility | Massing options tested against area, envelope and orientation; order-of-magnitude quantities | 100–200 |
| 2. Design | Multi-discipline coordination, spatial validation, design option comparison, drawing production | 200–300 |
| 3. Preconstruction | Constructability review, 4D sequencing, site logistics, quantity extraction | 300 |
| 4. Tender | Measured quantities supporting the bill; scope clarity reducing tender queries | 300 |
| 5. Construction | Clash detection, shop drawing basis, penetration drawings, field coordination, progress tracking | 350–400 |
| 6. Handover | Verified as-built model, asset tagging, structured asset data, open-format delivery | 500 |
| 7. Operation | Asset register, maintenance planning, fit-out basis, digital twin foundation | 500 |
Two supporting guides cover the mechanics: BIM levels of development for what each LOD actually supports, and ISO 19650 and BIM standards for the information management framework that keeps requirements consistent across stages. For the wider picture, see our guide to BIM in construction.
Who Owns What
Across the stages of a construction project, no single person controls every lifecycle responsibility, and pretending otherwise is how gaps appear at stage boundaries.
| Party | Owns | Most active in stages |
|---|---|---|
| Owner / client | Project objectives, budget, approvals, information requirements | 1, 4, 6, 7 |
| Project manager / PMC | Coordination of delivery across all parties | All |
| Design consultants | Design, documentation, submittal review, site support | 2, 5 |
| Cost consultant / QS | Estimates, bills of quantities, valuations, variations | 1, 4, 5 |
| Main contractor | Construction, programme, subcontract management, quality | 3, 5, 6 |
| BIM / information manager | Information standards, CDE, coordination process, handover data | All |
| Commissioning team | Testing, balancing, performance verification | 6 |
| Facility management | Operation, maintenance, asset performance | 6, 7 |
The party most often missing from early stages is the one that matters most at the end: facilities management. An FM team consulted at Stage 2 can state what the asset information deliverable needs to contain. Consulted at Stage 6, they can only report what is missing.
Seven Construction Project Stage Failures
| Failure | What it causes | The fix |
|---|---|---|
| Framework never agreed | “Stage 3” means different things to different parties in the same meeting | Establish the governing framework and stage definitions at appointment |
| Committing on a feasibility estimate | Cost growth as design develops, treated as failure rather than as expected | Match the estimate class to the decision; state the accuracy range |
| Design closed without written approval | Abortive work when the scheme changes after the next stage starts | Close each stage with a documented gate |
| Approvals assumed instantaneous | Every fabricated package starts late | Model approval durations as activities with predecessors |
| Preconstruction compressed | An unexecutable programme and a baseline nobody can defend | Protect the planning stage; a compressed plan costs more than it saves |
| Handover requirements written at handover | An operator inheriting files they cannot use | Write asset information requirements at Stage 1 |
| FM consulted at the end | Nobody stated what the asset deliverable had to contain | Bring facilities management into the design stage |
Frequently Asked Questions
What are the stages of a construction project?
The defined phases a project moves through from the decision to build to operation of the finished asset. A practical seven-stage view runs: feasibility and initiation, design, preconstruction and planning, tender and procurement, construction, commissioning and handover, and operation and maintenance. Each stage produces something the next depends on.
Why do sources say four, five, six or seven stages?
Because the stages organise responsibility rather than describing an objective property of the building, and responsibility looks different depending on who is asking. A project manager’s framework runs initiation to closure. An owner’s runs feasibility to decommissioning. A contractor’s runs award to handover. A designer’s runs brief to construction documents. None is wrong; they answer different questions.
What is the CMAA five-stage framework?
A widely used framework from the Construction Management Association of America defining the construction lifecycle in five stages: pre-design, design, procurement, construction and monitoring, and post-construction. It is one of the few frameworks in common use that is attributable to a named professional body.
How do RIBA stages map to these frameworks?
Broadly: RIBA Stages 0 and 1 cover feasibility and briefing, Stage 2 is concept design which corresponds to AIA schematic design, Stage 3 is spatial coordination, Stage 4 is technical design, Stage 5 is construction, and Stages 6 and 7 cover handover and use. The mapping is a translation rather than an equation, and RIBA stage numbering has changed between editions, so always read the actual scope of services.
Does the project end at handover?
It depends on the viewpoint. A contractor’s main delivery obligations reduce after contractual handover. From the owner’s asset perspective, the lifecycle continues into operations, maintenance, warranty, refurbishment and eventually replacement or decommissioning — which is usually the longest and most expensive part of the whole lifecycle.
Which stage is most often compressed?
Preconstruction and planning, because it produces no visible progress and sits between an approved design and a client wanting to see work start. Compressing it produces an unexecutable programme and a baseline nobody can defend later, which costs far more than the time it appeared to save.
What approval gates apply on Gulf projects?
In Saudi Arabia: land use and plot regulations, municipal permit review, Saudi Building Code compliance, Civil Defence review, and the occupancy certificate — which since a 2024 decision is a prerequisite for full activation of electrical current. In the UAE: plot data and affection plan, master developer design review, municipal review including IFC model submission in Dubai, Civil Defence, green building requirements, and utility approvals.
How should approvals be handled in the programme?
As real activities with real durations and predecessors, not as assumed instants. They are also sequential — authority review follows consultant review, so a package that only just cleared internal review has no float remaining. And they are layered, with a single project potentially facing master developer, municipal, Civil Defence, green building and utility gates.
What does BIM contribute at each stage?
At feasibility, massing options and order-of-magnitude quantities. At design, multi-discipline coordination and drawing production. At preconstruction, constructability review and 4D sequencing. At tender, measured quantities supporting the bill. During construction, clash detection, shop drawing basis and penetration drawings. At handover, a verified as-built model with asset data. In operation, the asset register and digital twin foundation.
Who is responsible across the stages?
No single party controls every responsibility. The owner retains project objectives and information requirements. Project managers coordinate delivery. Designers, cost consultants, contractors, BIM managers, commissioning teams and facility managers each lead different activities at different stages. The party most often missing early is facilities management, which is the one that matters most at the end.
When should handover requirements be defined?
At Stage 1, in the information requirements, not at Stage 6. Everything an operator needs exists during construction in the hands of people who will move on, and capturing it then costs a fraction of reconstructing it afterwards. Writing the requirements at handover produces an operator inheriting files nobody structured for them.
What closes a stage?
A documented gate — a decision, an approval or an issued deliverable that the next stage depends on. Stages that end because the programme said so rather than because the gate was passed push unresolved work forward, and the failures that hurt most on construction projects happen at these joins rather than inside the stages themselves.
Conclusion
The disagreement about how many stages a construction project has is not a problem to resolve — it is information. Each framework tells you whose job it was written to organise, and the practical requirement is simply to know which one governs your deliverables before someone says “Stage 3” in a meeting.
What the frameworks share is more useful than what divides them: every stage produces something the next depends on, and the expensive failures happen at the joins. In Saudi Arabia and the UAE the joins are harder, because several of them are decided by an authority rather than by the team — and those gates are activities with durations, not administrative formalities. Map them at the start, close each stage with a documented gate, and write the handover requirements while the information still exists.
Let’s get the deliverables right at every gate.
AMC Engineer delivers federated LOD 300–500 BIM modelling, clash detection and construction documentation for contractors, consultants and developers across Saudi Arabia and the UAE — from feasibility massing through to a handover model an operator can actually use.
