Construction projects can differ from one another in terms of complexity, scope, and objectives. Nevertheless, almost all construction projects go through the same fundamental stages of the construction process.
Understanding this process properly allows better decisions to be made from the initial idea of a project through to its completion. Although the construction process is complex and demanding, proper planning forms the foundation of a successful construction experience.
The construction process can generally be divided into the following six main stages:
Project concept, design, and planning
Obtaining construction permits
Preconstruction phase
Procurement and purchasing phase
Construction phase
Post-construction phase
Proper construction project management clearly defines what will happen at each stage, what tasks need to be completed, and what objectives need to be achieved.
Maintaining continuity throughout all stages of the project is extremely important. This approach helps ensure that the project is completed according to the planned schedule and within the established budget.
Proper execution of each construction stage creates the foundation for the successful completion of the project.
1. Project Concept, Design, and Planning
The project concept is the stage where the initial ideas are developed before construction begins. At this stage, the location of the project is determined, while the main requirements for the building and applicable construction regulations are investigated.
It is important to involve an architect in the process at this stage because the architect evaluates whether the project can be implemented from both technical and functional perspectives.
Feasibility studies determine whether the proposed solutions are consistent with the main objectives of the project.
After the concept stage, the client, architect, and construction manager move into the design stage. This stage creates a roadmap that defines the project objectives, expected challenges, and implementation strategy.
Design Stage
After the concept has been developed, the design process begins. Design work is carried out before the procurement of materials and services and before the construction process.
The architect and their team transform the client’s ideas into technical documentation and design solutions.
The design process includes the following stages:
Schematic design
Preparation of contract documents
Design development and detailed design
Before starting the schematic design, the main objectives and expectations of the project are established. Important decisions regarding the size of the building, its functional use, and spatial organization are made at this stage.
The design is then developed to demonstrate the organization of spaces, material selection, and initial technical solutions.
At this stage, an initial cost estimate is prepared and preparations are made for the tender process.
Architects evaluate the feasibility of the project and apply modern architectural solutions. Engineers ensure the safety and technical stability of the structures.
Architects and engineers complete the main design work during the preconstruction preparation stage.
After the design is completed, the project planner develops a strategic implementation plan. The project is divided into smaller stages, and implementation periods are established for each part.
2. Obtaining Construction Permits
All necessary construction permits must be obtained before starting the implementation of the project.
This process may continue throughout different stages of the project because various permits and approvals may be required for different aspects of the development.
Obtaining construction permits can sometimes take a considerable amount of time. This is because different government and local authorities may assess the project separately.
If special approvals or urban planning permissions are required for the project, they must be obtained before construction begins.
These approvals determine the intended use of the building and whether it complies with urban planning regulations.
While this process may be relatively simple for some projects, it can take months or even years for large and complex developments.
Working with an experienced project manager can help manage this process more efficiently and reduce potential risks.
3. Preconstruction Phase
This stage includes all preparatory activities carried out before physical construction begins.
Once project planning has been completed, design solutions have been finalized, and the organization of materials and labor has been determined, the preparation for construction begins.
Preconstruction services are important for determining:
Project cost
Scope of work
Construction schedule
Implementation strategy
At this stage, the project team is formed and the project management structure is established.
The team typically includes:
Project manager
Site engineer
General contractor
Construction manager
Health and safety specialist
The condition of the site is also carefully examined during this stage.
After the site has been assessed, the actual project cost is calculated. The following factors are taken into consideration:
Labor
Materials
Schedule
Site conditions
Legal and technical requirements
The contractor evaluates whether the project can be completed within the established budget.
Following this stage, a legal contract is signed between the parties, giving the contractor the authority to carry out the construction works on behalf of the client.
4. Procurement and Purchasing Phase
During the procurement stage, the resources required for the project are secured, including:
Materials
Equipment
Labor
The complexity of this stage depends on the size of the project, its planned start date, and the availability of resources.
At this stage, the general contractor enters into agreements with various specialized subcontractors.
Based on the construction drawings, the required scope of work is determined, and subcontractors prepare their work programs, material requirements, and resource plans.
A proper procurement strategy helps reduce the overall cost of the project.
Contractors with a reliable network of suppliers can obtain more competitive prices and improve the economic efficiency of the project.
5. Construction Phase
The construction phase is the stage in which the project is physically implemented. During this stage, the planned ideas are transformed into a physical structure.
Before construction begins, an initial coordination meeting is held to ensure that all participants are working toward the same objectives and following the same plan.
The following issues are discussed during this meeting:
Logistics and material storage
Main contract conditions
Health and safety
Quality control
Possible project changes
Once construction begins, the general contractor takes overall responsibility for management.
The contractor:
Manages resources
Controls documentation
Reports on project progress
The architectural and engineering team, meanwhile, checks whether the work complies with the approved design.
They review:
Material changes
Additional work orders
Technical submissions
At this stage, each team has its own work schedule. The completion of one team’s work may affect the activities of other teams.
For this reason, effective management is extremely important during the construction phase.
Monitoring and Control
Monitoring and control are particularly important in construction project management.
The construction manager monitors:
Budget
Risks
Insurance matters
Scope of work
Key performance indicators (KPIs) are used during this stage.
Examples of KPIs include:
Cost tracking
Schedule compliance
Project objectives
Deliverables
6. Post-Construction Phase
The completion of construction does not necessarily mean that the project is completely finished.
At this stage, all final activities are carried out before the building is handed over to the client.
Resources that are no longer required for the project are removed from the site, rented equipment is returned, and the construction site is cleaned.
The project manager and engineers inspect the facility and identify any incomplete works.
Any deficiencies identified are documented and corrected by the contractor.
The following documents are provided to the client:
Operation manuals
As-built drawings
Financial documents
Insurance documents
For large projects, this stage is often carried out as a dedicated commissioning process. During commissioning, engineering systems are tested and their compliance with the project requirements is verified.
Conclusion
The construction process is a multi-stage process that begins with the formation of an idea and continues through to the full commissioning and use of the facility.
Each stage — design, obtaining permits, preparation, procurement, construction, and final evaluation — plays an important role in the successful implementation of the project.
A properly planned and professionally managed construction process forms the foundation for high-quality, safe, and long-lasting projects.
