Quality management in construction: 12 processes to succeed

Quality has always been the mark of good construction. From master builders inspecting stone by hand to today’s digital site teams, the goal has stayed the same: deliver work that meets the required standard the first time.

According to the 2026 Construction Management and Chartered Institute of Building (CIOB) client survey, 76% of clients rank quality of work as their top priority when choosing a contractor, even ahead of cost certainty.

But delivering quality is more challenging than it used to be.

Projects are bigger, teams are more fragmented, and compliance requirements are more demanding than ever. That’s why getting quality management right takes structured planning, inspection, and oversight at every level of a project.

If you’re looking to improve quality management in construction, start with the 12 essential processes outlined below.

Key takeaways

• Quality management combines QA and QC
  QA prevents defects through the right processes, while QC verifies that completed work meets the required standards.

• Quality starts before construction begins
  Strong planning, design reviews, workforce training, and supplier approval reduce defects before work starts on site.

• Continuous improvement reduces repeat issues
  Tracking non-conformances and lessons learned helps strengthen your quality management system over time.

• Digital quality management simplifies compliance
  Onetrace centralises inspections, approvals, documentation, and reporting, making it easier to deliver compliant, high-quality projects.

What is quality management in construction?

Quality management in construction is the system of processes used to plan, monitor, deliver, and improve quality throughout a project.

It combines quality assurance (QA), which focuses on preventing defects through the right processes, and quality control (QC), which checks completed work against the required standards.

Together, QA and QC cover every part of project delivery, from people and processes to materials, workmanship, and finished work.

The ultimate goal of QA and QC processes is to stop failures reaching the finished work. When successful, these processes help:

• Reduce costly rework

• Keep projects on programme

• Support compliance

• Protect tight profit margins

Effective quality management also creates a consistent standard of delivery across multiple field teams and subcontractors.

Who is responsible for quality management in construction?

In construction, quality management is a shared responsibility.

While a dedicated quality manager or QA/QC team often coordinates the process, delivering quality depends on everyone involved in planning, supervising, executing, and inspecting the work.

Quality management in construction: 6 essential QA processes

Here are the six QA building blocks of effective quality management in construction.

1. Quality Management System (QMS) and quality planning

A Quality Management System (QMS) is the framework that defines how quality is managed across a construction business. It sets the policies, procedures, responsibilities, and standards that help teams deliver consistent results, meet regulatory requirements, and continuously improve.

Many contractors base their QMS on ISO 9001, the world’s most widely used quality management standard.

A company-wide QMS should then be translated into a project-specific Quality Management Plan (QMP) before work begins.

The plan defines the project’s quality objectives, roles and responsibilities, inspection requirements, documentation, and acceptance criteria, giving everyone a clear understanding of how quality will be managed on site.

A well-built quality plan should be practical rather than performative. This means it should:

• Reflect how work will actually be delivered on site

• Be accessible to everyone who needs it

• Stay up to date throughout the project

Pro tip:

Build your quality plan around the client’s priorities, not just your internal processes.

Understanding whether quality, programme, cost, sustainability, or long-term performance matters most to your client helps set realistic objectives and focus quality efforts where they’ll have the greatest impact.

2. Building Safety Act and the golden thread setup

A single construction project can generate thousands of documents, including drawings, specifications, RFIs, material declarations, inspection records, test results, and design changes.

Managing these records properly isn’t just about staying organised.

It’s what allows every contractor, subcontractor, and inspector to:

• Work from the same approved information

• Maintain a complete record of key decisions

• Prove that work was carried out in accordance with project requirements

For higher-risk buildings, effective document management is also a legal requirement.

Under the Building Safety Act 2022, dutyholders must maintain a golden thread of information—a secure, accurate, and up-to-date digital record of safety-critical information that follows the building from design through construction and into occupation.

Even where the Building Safety Act doesn’t apply, the same principles represent good practice.

Maintaining accurate, accessible, and version-controlled project information offers numerous benefits, including reducing quality risks, simplifying handover, and providing a reliable audit trail throughout the project lifecycle.

Pro tip:

Start building handover documentation and O&M manuals from day one.

Keeping records up to date throughout the project makes handover much smoother and ensures the golden thread continues into the building’s operational life.

3. Design risk management and constructability reviews

Many construction quality problems originate long before work starts on site.

Design reviews and constructability assessments help identify these issues early, when they’re far easier and less expensive to resolve. A typical review should cover:

• Compliance with the Building Regulations 2010 and other project requirements

• Coordination between structural, architectural, and MEP designs

• Buildability and sequencing before work begins

• Design clashes using BIM and other coordination tools

• Safety risks and designer duties under the Construction (Design and Management) Regulations 2015

Resolving design issues before construction begins reduces uncertainty on site, minimises changes during delivery, and gives every contractor and subcontractor a clearer standard to build against.

Pro tip:

Involve site teams and specialist subcontractors in design reviews wherever possible. They often identify practical construction issues that aren’t obvious from drawings alone.

4. Workforce competency and quality training

An older exploratory study published in the International Journal of Quality & Reliability Management ranked human resource management as the single biggest driver of quality in construction, ahead of customer satisfaction and construction-specific factors like code compliance, technical specification adherence, and design constructability.

In practice, this means that construction quality is largely determined by how well people are prepared to do the job.

That’s why quality management should include:

• Structured inductions

• Toolbox Talks

• Trade-specific training

• Competency assessments

• Ongoing professional development

In addition, everyone carrying out specialist work should have the appropriate qualifications and certifications, such as relevant CSCS cards.

Investing in workforce competency reduces errors, improves workmanship, and helps close the gap between how a building is designed to perform and how it performs in practice.

Pro tip:

Use a construction site management platform like Onetrace to manage workforce competency in one place.

With the platform’s Signed Docs feature, you can:

• Store certificates, job instructions, and other competency records in a central location

• Distribute Toolbox Talks and other mandatory documents directly to operatives while tracking acknowledgements and signatures in real time

• Maintain a complete audit trail demonstrating that operatives were trained, informed, and authorised to carry out the work

5. Supply chain pre-qualification and material compliance

Even highly competent site teams can’t deliver quality if they’re working with the wrong suppliers or non-compliant materials. That’s why every organisation involved in the project should have a structured and standardised process for approving specialist subcontractors, suppliers, and products before work begins.

For subcontractors and suppliers, the verification process may include recognised pre-qualification schemes such as the Common Assessment Standard (CAS).

As for materials, businesses should ensure compliance with:

• The contract specification

• Relevant British Standards (BS/BS EN)

• Applicable product certifications, such as UKCA marking

Technical submittals, manufacturer documentation, and third-party certifications provide evidence that products are suitable before they reach the site.

6. Continuous improvement and corrective actions

Quality management doesn’t end when a project is complete.

Every audit, non-conformance, recurring defect, and lesson learned should be used to strengthen the processes behind future projects.

The ultimate goal is to improve the QMS so the same problems are less likely to happen again.

Pro tip:

Maintain a non-conformance (NC) register and analyse recurring issues over time.

Identifying patterns across multiple projects and targeting the root causes of quality failures costs less over time than repeatedly fixing the same defects.

Quality management in construction: 6 essential QC processes

Once construction begins, the focus shifts from preventing defects to verifying quality. These six QC processes ensure work complies with project requirements before it progresses.

1. Incoming material inspection

Before materials are incorporated into the works, they should be inspected to confirm they match what was specified and approved. This inspection typically includes verifying:

• The correct product, quantity, and dimensions

• Product condition and any signs of damage

• Compliance with the approved specification

• Required certifications and accompanying documentation

Materials that don’t meet the project requirements should be identified, segregated, and rejected before installation.

2. Inspection and Test Plan (ITP) execution

Inspection and Test Plans (ITPs) are developed during the quality planning stage. Once construction begins, they become a vital QC tool, ensuring inspections and testing take place at the right stages before work progresses.

An ITP typically defines:

• What needs to be inspected or tested

• When inspections or hold points occur

• Who is responsible for carrying them out

• Which acceptance criteria must be met before work can proceed

Executing the ITP involves carrying out and digitally recording all required quality verification activities throughout construction.

Depending on the scope, these might include:

• Concrete cube compressive testing

• Airtightness testing

• Acoustic performance testing

• Passive fire stopping inspections

• MEP commissioning

• Third-party accredited testing

Inspection records, test results, commissioning certificates, and sign-offs form part of the project’s golden thread of information.

3. Benchmarking, mock-ups and sample approvals

Before large-scale construction begins, benchmark installations, mock-ups, and material samples establish the expected standard of workmanship, appearance, and performance.

Once approved, they become the reference point against which the remaining work is inspected.

This process is particularly valuable for complex details, high-value finishes, or repetitive work, where identifying issues early prevents defects from being repeated across the project.

4. Site inspections and workmanship verification

Regular site inspections validate that work is being carried out in accordance with the approved drawings, specifications, and quality standards. Unlike benchmark inspections, they assess the quality of ongoing work throughout the project.

These inspections should verify:

• Workmanship and installation quality

• Compliance with approved drawings and specifications

• Dimensional tolerances and alignment

• The quality of finishes and completed work

Any non-conformities should be recorded and corrected before subsequent activities begin.

Pro tip:

Use QR codes to link completed work to its inspection records.

With Onetrace, operatives can tag installations with a QR code that provides instant access to the full history of inspections, job sheets, and maintenance activities, making workmanship easier to assess.

5. Non-conformance and defect management

When work fails to meet the required specification, the issue must be formally recorded, investigated, and corrected before construction can continue.

A structured non-conformance process prevents defective work from being concealed by subsequent trades and ensures all quality issues are resolved before handover.

As part of this process, you should create a Non-Conformance Report (NCR) to:

• Document work that fails inspection

• Identify the immediate cause

• Assign corrective actions

• Verify remedial work

• Formally close out the issue

6. Practical completion, snagging and final verification

Before a project can be handed over, the completed works must be inspected, tested, and verified to confirm they meet the contract requirements, design intent, and applicable statutory standards.

This final stage ensures all outstanding issues have been resolved, required documentation has been completed, and the building is ready for occupation or client acceptance.

Key parts of this QC process include:

• Snagging and final defect verification: Conduct pre-handover inspections, produce snag lists, track outstanding items, examine remedial works, and confirm all defects have been closed out before practical completion.

• Final inspection, testing, and commissioning: Complete final inspections, statutory testing, and systems commissioning, including Building Control approval and, where applicable, compliance with the Building Safety Act requirements for higher-risk buildings.

• As-built documentation and handover: Verify as-built drawings, O&M manuals, warranties, test certificates, and other handover documentation to demonstrate compliance with contractual and regulatory requirements.
