The 6 Key Construction Project Phases: Complete Guide

What Are the Six Key Construction Project Phases?

Dividing projects into phases ensures you don’t miss any detail while allocating resources. Construction projects are no different. By following a structured path of six key phases, you lay a foundation for smooth execution and reduced risks throughout your project.

Here is a quick overview of the six phases of construction projects.

1. Pre-construction phase

This is the first phase of construction project management and typically involves feasibility studies, budgeting, site analysis, and assembling the project team. The pre-construction phase ensures all stakeholders are aligned before design work begins.

2. Design phase

Here, architects, engineers, and planners work together to develop detailed plans and specifications. The goal during this planning phase is to create detailed and comprehensive designs that determine the scope of the project.

3. Procurement phase

During procurement, materials, equipment, and subcontractors are sourced. The procurement phase is a delicate one as strategic purchasing helps ensure that everything is available on time, preventing potentially costly delays.

4. Construction phase

The construction phase is the execution stage where plans come to life. During this phase, the project manager oversees daily operations to ensure quality control, safety, and adherence to the project design.

5. Close-out phase

After construction comes the close-out phase, which includes final inspections, checklists, and handovers. This phase ensures all contractual obligations are fulfilled and the client receives a complete, functional asset.

6. Post-construction phase

Even after project delivery, you’ll typically need to provide continued support through maintenance plans and performance evaluations. This ensures long-term client satisfaction and repeat business.

Keep reading as we dive into the finer details of these six phases.

Phase 1: How Does Pre-Construction Set the Foundation for Success?

The pre-construction phase lays the groundwork for construction success as it’s the stage where ideas are translated into executable plans. During this planning phase, specific goals are defined, budgets are created, risks are anticipated, and teams are aligned. Done right, it sets the tone for clarity and control throughout every other phase.

We’ll break down the pre-construction phase into two stages.

Conducting feasibility studies and defining project scope

This first step is all about asking the right questions: 

• What are we trying to achieve?

• Is this project viable? 

• What are the constraints? 

Feasibility studies examine everything from job site conditions to regulatory requirements to determine whether the project should proceed. Once feasibility is confirmed, the next step is drawing up a clear project scope. Misalignment at this stage, such as vague deliverables or poorly written contracts, can create confusion and other issues as the project unfolds.

Creating detailed project plans and budgets

Once you get the green light to proceed, your construction team can begin building out the project roadmap. This typically includes creating a Project Initiation Document, outlining timelines, key milestones, and cost projections. 

ServiceTitan can help here.

With ServiceTitan’s Estimate feature, you can create budget scopes and pricing breakdowns for your construction project quickly and accurately. This feature lets you draw up comprehensive estimates that include everything from labor costs to materials and equipment costs, ensuring that nothing is overlooked during budget planning.

In addition, you can customize these estimates for various phases of the construction project, or to reflect change orders. This way, you reduce the chances of financial surprises later on in the project. 

Phase 2: Why Is Design Crucial in Construction Project Management?

From blueprints to budget planning, the design phase helps align the vision with the results from the feasibility studies.

Here are the two primary aspects of the design phase in construction project management.

Developing blueprints and risk assessments

During this stage, architects, engineers, and project managers collaborate to create detailed blueprints outlining the proposed project’s structural, electrical, and mechanical components. The team typically conducts risk assessments to ensure the design aligns with financial and environmental realities. 

This process helps flag potential issues such as zoning limitations, utility conflicts, or environmental hazards. 

Establishing roles and responsibilities

Another goal of the design phase is to define team roles and responsibilities to avoid confusion during execution. When every stakeholder and team member knows their role, you’ll achieve smoother coordination and clear accountability as the project progresses.

Here’s a quick overview of key stakeholders in a construction project and their responsibilities:

• Project Owner: Typically responsible for setting the vision and approving plans and budgets.

• Architect/Engineer: The architect designs the functional and aesthetical aspects of the project while the engineer handles the structural design to ensure the construction is up to code.

• General Contractor: Oversees day-to-day operations on the job site.

• Subcontractors: Typically handle specialized tasks like electrical, plumbing, or HVAC.

• Construction Manager: Coordinates scheduling and resources, while ensuring clear communication between all parties.

• Safety Officer: Ensures the construction site meets safety standards and handles first aid in the event of a work incident.

ServiceTitan’s Dynamic Forms helps during the design phase of construction by enabling teams to document design approvals, responsibilities, and change requests digitally. All stakeholders can see real-time project updates and stay aligned as developments occur.

With automated tracking and centralized online storage, there’s a reduced risk of miscommunication or misplaced paper records of project details.

Phase 3: What Happens During the Procurement Phase?

At this stage, construction managers secure the necessary equipment, materials, and labor force to execute the project. While it may seem like mere buying or hiring, the procurement phase is a high-stakes process that requires precise coordination, good vendor relationships, and financial oversight to ensure everything arrives on time, within budget, and to the expected quality.

Here are the two main parts of the procurement phase:

Sourcing materials and hiring contractors

During procurement, you’ll source the right building materials, select qualified contractors, and manage supply chain logistics, which typically involve vetting vendors, negotiating terms, and coordinating deliveries. Unfortunately, fluctuating market prices or unexpected supply chain disruptions can easily derail project timelines.

ServiceTitan’s Inventory Tracking feature can help you avoid such setbacks by providing real-time visibility into material availability and equipment usage. With tools like Purchase Order Management, you can create, track, and manage POs and returns, manage approvals, and record receipts, all from one dashboard. 

Meanwhile, the Requisition Management feature ensures seamless coordination across multiple projects by allowing you to generate and track requisitions linked directly to your purchase order fulfillment.

Managing contracts and payments

Clear, legally sound construction contracts are critical for setting expectations and avoiding disputes during your project. A good legal agreement clearly defines deliverables, responsibilities, timelines, and payment terms. It’s also important to keep track of work progress and ensure payments are made on time.

ServiceTitan helps to simplify your financial oversight process with its Progress Billing feature, which enables your team to invoice payments based on completed milestones, improving cash flow accuracy. 

Its Work-in-Progress Report feature can also keep accurate snapshot records of the work status across your construction project, ensuring your billable amounts remain perfectly synced with the work done and the project timeline.

Phase 4: What Happens During the Construction Phase?

The construction phase is where you execute the project plans. Generally, this is the most visible and labor-intensive part of the project life cycle, requiring sharp coordination, real-time decision-making, and constant communication. Any gaps in the groundwork laid during the pre-construction and design phases will be exposed here. 

The construction phase involves three crucial aspects.

Mobilize teams and break ground

Before construction begins, you’ll typically need to carry out some preliminary work to ensure the site is ready for building and team members have all the necessary information, materials, and equipment for effective work.

• Site preparation: This includes demolishing existing structures, grading, and clearing land.

• Resource allocation: Equipment, materials, and labor are deployed to the site, ensuring everything needed is available from day one.

• Administrative setup: Clear communication protocols and safety systems are established to ensure smooth daily operations.

• Logistics coordination: Deliveries and equipment arrivals are scheduled to minimize delays and congestion on-site.

Track progress and manage daily operations

Once construction commences, it’s essential to conduct regular monitoring to ensure tasks are completed according to the construction schedule. This allows you to identify potential issues quickly before they snowball into costly delays or rework.

With the ServiceTitan Field Service App, you can unlock real-time communication between field and office teams, ensuring all stakeholders remain in sync throughout the project. 

In addition, its Crew Management feature helps you make smarter job assignment decisions based on real-time availability and skill. Its Automated GPS Timesheets ensure managers can track crew attendance and productivity, reducing time theft and improving oversight.

Handle change orders and on-site issues

Whether it’s weather delays, unexpected site conditions, or client changes, flexibility is vital in construction. 

It’s important to document change orders clearly and ensure they’re approved quickly to avoid scope creep. You can also use a centralized system to keep track of these changes, ensuring transparency and accountability.

Phase 5: What Is Involved in Close-out?

After months of project execution, the close-out stage is where you conduct a quality check to ensure every construction detail meets contract specifications and all stakeholders are aligned on the final deliverables. 

Here’s what you’ll need to do during the close-out stages of your construction project.

Conduct inspections and walkthroughs

First, you’ll need to conduct thorough inspections and walkthroughs to verify that all work aligns with the design brief and quality standards. You’ll also need to create a punch list, a list of tasks that still need correction or completion before final sign-off, to make sure everything is up to speed before handing over the project.

It’s also important to confirm all aspects of the project comply with local building codes and safety standards during this stage.

Collect documentation and release retainage

Once you’ve completed your quality checks, you need to create a comprehensive close-out document for the project. This document typically contains details of warranties, lien waivers, equipment manuals, and as-built drawings. Once you’ve compiled this file, you can then submit it and trigger the release of your retained payments. 

ServiceTitan’s Project Tracking feature helps you centralize all relevant project documentation, making it easier to upload, organize, and retrieve critical files throughout the project life cycle.

Transition to post-construction support

Finally, even after you’ve formally handed over the construction project to the clients, you retain the responsibility of carrying out warranty work and related client support. It’s a good idea to establish a clear process for post-construction services, including maintenance schedules and issue reporting.

Ensuring a proper transition to post-construction support demonstrates professionalism and reinforces client trust.

Phase 6: Why Is Post-Construction Important?

This phase focuses on finalizing the handover, supporting ongoing operations, and capturing key insights to improve future project delivery. While the post-construction phase is often overlooked, it actually plays a vital role in the construction project life cycle as it sets the stage for repeat business. 

Here’s what you typically need to do during the post-construction phase.

Ensure a smooth handover and occupancy

Successful construction management involves more than just turning over the keys. You’ll also need to transfer all operational information, such as user manuals, maintenance guidelines, and system training, to the property owners or tenants. This ensures occupants understand how to use and maintain the building systems, thereby minimizing future disruptions.

Deliver post-construction maintenance and support

After the handover or commissioning, you’ll need to offer post-construction support to ensure your client gets a good experience. Warranty checks, repair requests, and scheduled maintenance are all part of the builder’s continued responsibility. 

ServiceTitan’s Asset Tracking feature makes this process more manageable by providing a centralized record of installed equipment, service history, and upcoming maintenance schedules. In addition to helping you carry out post-construction duties more efficiently, it ensures systems stay operational long after the build is complete, since they’ll get regular maintenance.

Conduct a project review and lessons learned

Finally, you want to organize an in-house, post-project debrief to gain insight into how the construction project went. You should discuss what went well, what could be improved, and what processes can be refined. These insights play a key role in helping you fine-tune your workflows and improve performance on future jobs.
