6 Key Phases Of Construction Projects (RIBA Plan Of Work)
The construction sector is a massive part of the UK’s economy, bringing together a diverse mix of roles from general contractors and project managers to the hands-on skilled labourers.
This industry is behind the creation of everything from housing developments to imposing commercial towers and vital infrastructure. At its core, construction is all about well managed projects, each uniquely demanding in terms of scope, budget and scale.
In this article, we take a more indepth look at the six key phases of construction, breaking down the crucial activities and roles at each step to give you a clearer picture of how a construction project comes to life from start to finish.
Integrating the RIBA Plan of Work into Construction Project Stages
The RIBA Plan of Work organises the process of briefing, designing, constructing, maintaining, operating and using building projects into eight stages (0-7).
This framework is essential in the UK and widely recognised as a definitive model for managing and executing construction projects efficiently.
Created in 1963 for architects to use on projects, the framework has become an industry-wide tool to follow. It explains the expected outcomes, core tasks and information exchanges throughout the life of construction projects.
Understanding how each phase of a construction project aligns with the RIBA stages can help ensure that all necessary considerations and activities are addressed systematically.
Introduction to the Primary Phases of Construction
Construction projects are structured into six key phases, each essential for the project’s success.
From initial conception and feasibility assessment to the detailed planning in pre-construction, sourcing materials in procurement, the actual building in the construction phase and finalising in post-construction, each phase is critical to ensuring the project meets all specifications and quality standards.
Phase 1: Project Conception and Initiation
RIBA Stage 0 – Strategic Definition and RIBA Stage 1 – Preparation and Brief.
This phase sets the groundwork for the project, focusing on defining its feasibility and scope, aligning with RIBA’s initial stages where the project’s strategic goals and brief are developed.

Clear Project Scope: Ensures all team members understand the project boundaries, deliverables and objectives, minimising the risk of scope creep.
Practical Tips and Challenges
Tip: Use advanced simulation tools during site analysis to predict potential issues like water drainage or structural instability.
Challenge: Securing permits can be time-consuming and unpredictable. Engage with local authorities early to understand all requirements and timelines.
Phase 3: Design Phase
RIBA Stage 3 – Developed Design and RIBA Stage 4 – Technical Design
These stages refine the design into detailed plans and specifications for the construction project, encompassing the development of design documents and technical specifications.
Exploration of Design Processes
Schematic Design: Initial concepts and sketches that outline the basic layout and functional elements of the project.
Design Development: Further refinement of the schematic designs into more detailed and specified plans.
Construction Documents: Final, detailed drawings and specifications used for construction bidding, permitting and building.
Iterative Design Process
Collaboration: Ongoing interaction among the design team, project management team and client ensures that the project meets all expectations and requirements.
Feedback Integration: Regular reviews and feedback from the client are integrated into the design to address any concerns or modifications needed.
Roles Involved in the Design Phase
Design Team and Architects: Lead the creative and technical aspects of project design.
Engineers: Provide structural, mechanical, and electrical expertise to ensure the project is feasible and compliant with regulations.
Client Feedback Mechanisms: Essential for ensuring that the client’s vision and requirements are accurately incorporated into the project.

General Contractors: Often involved in selecting subcontractors and managing supply chains for materials.
Subcontractors: Specialised roles depending on project requirements, selected for specific tasks within the project.
Practical Tips and Challenges
Tip: Develop a clear procurement strategy that includes vetting suppliers for reliability and quality, not just cost.
Challenge: Fluctuations in material costs and availability can disrupt your budget and schedule. Consider locking in prices with suppliers or keep a contingency budget for these variables.
Essential Phase 4 Construction Procurement Strategies
Understanding different procurement methods is essential for managing the impact on project costs and timelines. Here’s a concise overview of popular procurement strategies:
Design-Bid-Build (Traditional Method):
Process: This method involves three sequential steps, which are: design, bid and build. First, the design is completed by an architect or engineer, then bids are requested from contractors and finally, the project is built by the winning bidder.
Impact: Provides clear project specifications before bidding, often leading to more accurate budgeting but can be time-consuming.
Design and Build:
Process: This integrated approach assigns both design and construction responsibilities to one entity. The contractor is involved from the design phase and carries the project through to construction.
Impact: Can accelerate project timelines by overlapping design and construction phases. However, it may reduce the client’s control over the design.
Management Contracting:
Process: The client hires a management contractor to oversee the entire construction operation, while different works are subcontracted. The management contractor does not carry out the construction but manages the process.
Impact: This method allows for greater flexibility and faster project delivery as construction can start before the design is finalised. However, it might involve higher costs due to the need for intense management and coordination.
Each procurement strategy has its strengths and challenges and the choice depends largely on the project requirements, timelines, risk appetite and budget constraints.
Choosing the right strategy can significantly influence the efficiency and success of a construction project.
Phase 5: Construction
RIBA Stage 5 – Construction
Directly corresponds to the physical building activities, where the project is brought to life as per the planned designs and specifications.
Construction Process
Site Preparation: Involves clearing, excavation and levelling the construction site as necessary before actual building begins.
Building: The physical construction of the structure, following the detailed plans from the planning phase and specifications from the design phase.
Execution of Project Plans and Construction Schedule
Project Management: Ensuring that the construction adheres to the predefined schedules and plans.
Adaptability: Adjusting strategies in real-time to handle unforeseen delays or issues.
Ensuring Quality and Safety
Quality Control: Continuous oversight to ensure that construction meets all specified standards and codes.
Safety Measures: Implementing strict safety protocols to protect workers and the environment.
Change Orders: Managing changes in the project scope efficiently to minimise disruptions and cost overruns.
Roles Involved in the Construction Phase
Field Engineers: Monitor the daily operations and ensure that construction meets the architectural plans.
Construction Workers: Execute the physical work of building the project, from foundation to finishes.
Quality Control Specialists: Ensure that all aspects of construction adhere to the highest quality standards and comply with legal and contractual agreements.
Practical Tips and Challenges
Tip: Regular on-site meetings with the construction manager and all subcontractors can help keep the project on track and preemptively address issues.
Challenge: Safety incidents can cause significant delays and legal issues. Implement rigorous safety protocols and continuous training for all site workers.
Phase 6: Post-Construction
RIBA Stage 6 – Handover and Close Out and RIBA Stage 7 – In Use
This phase includes all activities necessary to transition the project from construction to operational use, ensuring all standards are met and the project is ready for handover as outlined in the final RIBA stages.
Completion and Final Assessments
Final Inspections: These ensure the building complies with all building codes, legal requirements, and matches the project specifications.
Punch List Completion: Addressing the final minor defects or unfinished elements identified during the inspections.
