Five Ways Unexpected Asbestos Can Delay Your Construction Project

Construction projects are built around careful planning, tight schedules and strict budgets.

Whether you’re refurbishing a commercial office, redeveloping an industrial site or carrying out demolition work, unexpected issues can quickly impact programme timelines and increase costs.

One of the most common – and avoidable – causes of project delays is the unexpected discovery of asbestos.

Despite being banned in the UK in 1999, asbestos-containing materials (ACMs) remain present in many commercial, industrial and public buildings. If these materials are discovered after work has started, projects can grind to a halt while appropriate investigations and control measures are put in place.

At Acron Asbestos, we work alongside contractors, developers, property owners and project managers to help identify asbestos risks before work begins, reducing delays and supporting safe, compliant construction projects.

Here are five ways unexpected asbestos can delay your project – and how early planning can help avoid them.

1. Work Must Stop Immediately

If suspected asbestos is discovered during refurbishment or demolition work, construction activities within the affected area may need to stop immediately.

This pause allows the material to be assessed, sampled and, where necessary, managed or removed safely before work can continue.

For projects operating to strict deadlines, even a short delay can have a significant impact on the overall programme.

By arranging a Refurbishment and Demolition Survey before work begins, asbestos-containing materials can often be identified long before contractors arrive on site.

2. Additional Surveys and Sampling Become Necessary

Unexpected asbestos often leads to additional investigations that were not originally included within the project programme.

This may involve:

• Emergency asbestos sampling
• Laboratory analysis
• Additional asbestos surveys
• Risk assessments
• Consultant site visits

While these activities are essential for protecting health and safety, they inevitably add time to the project.

Planning asbestos surveys during the early stages of project development allows these investigations to be completed before construction work begins.

3. Contractors May Be Forced to Leave Site

If asbestos is identified unexpectedly, contractors may be unable to continue working safely until the issue has been resolved.

This can create several knock-on effects, including:

• Lost labour hours
• Rescheduled subcontractors
• Plant and equipment downtime
• Delayed follow-on trades
• Extended project durations

Where multiple contractors are involved, even a relatively small delay can affect the wider construction programme.

Early asbestos consultancy helps minimise the risk of these avoidable interruptions.

4. Project Costs Can Increase Quickly

Unexpected asbestos doesn’t just affect timescales – it can also impact budgets.

Additional costs may include:

• Emergency surveys
• Asbestos sampling
• Air monitoring
• Licensed asbestos removal
• Temporary site closures
• Programme extensions
• Additional contractor costs

Many of these expenses can be significantly reduced through effective planning and early asbestos management.

A professional asbestos consultancy helps clients understand potential risks before they become costly problems.

5. Compliance and Health & Safety Responsibilities Become More Complex

Construction projects involve a range of legal responsibilities relating to health and safety.

If asbestos is discovered unexpectedly, duty holders may need to:

• Review risk assessments
• Update construction programmes
• Appoint specialist contractors
• Arrange independent air monitoring
• Demonstrate compliance with the Control of Asbestos Regulations 2012

Failure to manage asbestos correctly can place workers at risk while also exposing organisations to enforcement action and reputational damage.

Planning ahead helps ensure projects remain compliant from the outset.

Why Early Asbestos Surveys Save Time and Money

One of the simplest ways to avoid asbestos-related delays is to commission the appropriate asbestos survey before refurbishment or demolition work begins.

A Refurbishment and Demolition Survey is specifically designed to identify asbestos-containing materials that may be disturbed during planned works.

Unlike an Asbestos Management Survey, it involves intrusive inspection of the areas affected by construction, allowing project teams to understand potential risks before work starts.

This enables:

• Better project planning
• More accurate budgeting
• Safe contractor scheduling
• Planned asbestos removal where necessary
• Reduced risk of programme delays

Early planning almost always proves more cost-effective than reacting to unexpected discoveries once work is underway.

Supporting Construction Projects from Start to Finish

At Acron Asbestos, we support construction professionals throughout every stage of a project.

Our services include:

• Refurbishment and Demolition Surveys
• Asbestos Management Surveys
• Asbestos Sampling
• UKAS-accredited Air Monitoring
• Independent Asbestos Consultancy
• Project Management
• Asbestos Training

Whether supporting a commercial refurbishment, industrial redevelopment, healthcare project or educational facility, our experienced team helps clients manage asbestos safely while keeping projects moving.

Why Independent Consultancy Matters

Independent asbestos consultants provide objective advice based on survey findings, legislation and best practice.

Rather than reacting to problems after they occur, we work with clients to identify risks early and develop practical solutions that support project delivery.

This independent approach gives property owners, developers and contractors confidence that asbestos is being managed professionally and transparently throughout the construction process.

Plan First, Build with Confidence

Unexpected asbestos remains one of the most common causes of avoidable construction delays.

By identifying asbestos-containing materials before refurbishment or demolition begins, organisations can protect workers, maintain compliance and keep projects on schedule.

Whether you’re planning a commercial refurbishment, industrial redevelopment or public sector construction project, early asbestos consultancy provides the knowledge needed to move forward with confidence.
