How to Handle a Construction Project Delay

Construction projects are notoriously complex, with many moving parts that can shift timelines and strain budgets. For contractors and subcontractors working under the Construction Industry Scheme (CIS), delays can be even more damaging as they might also cause financial problems.

Sometimes, delays can lead to financial disputes and increased scrutiny from HMRC, which is why employing a specialist company to protect contractors and subcontractors, like the team here at Contractwise, is often a sensible decision. We offer a wide range of services to keep construction businesses CIS compliant, including payroll audits, which minimise the risk of a costly HMRC reclassification.

In this article, we’ll take a closer look at the issues construction project delays can cause, as well as how to properly handle them.

Reasons for a construction delay

Delays in construction projects are common, but they often stem from predictable causes. That’s not to say that sometimes unpredictable events may not crop up, which also cause a delay. Whatever the case, understanding these causes is the first step towards handling and mitigating them effectively.

The most common reasons for a construction delay include:

Lack of funding

Insufficient or delayed funding is one of the biggest reasons for a delay. This usually happens when clients or developers face financial difficulties, and it may cause payments to stall and progress on a site to grind to a halt.

Going over budget

Mismanaged budgets or unexpected costs can also lead to financial strain. If the allocated funds are inadequate to meet rising expenses, projects will often pause until more money is provided - resulting in a delay.

Shortage of labour

The construction sector is constantly facing skills shortages. A lack of qualified people to get the job done can slow progress, especially if specialist expertise is required in order to proceed.

Lack of proper planning

Poor planning during the early stages of a project can snowball into larger issues later down the line. Without detailed scheduling, risk assessments and resource allocation, a project will suffer from inefficiencies which can cause delays.

Weather

The UK’s unpredictable weather can also be a serious barrier to progress. Heavy rainfall, storms and freezing conditions can make it unsafe or impractical to work on outdoor sites, meaning work needs to stop until the weather changes.

Injury or accidents

Health and safety incidents not only affect the workforce but can also trigger investigations and, in severe cases, site closures that further delay completion.


Issues caused by a construction delay

Project delays can carry a wide range of negative consequences, including:

  • Increased costs: The biggest worry of an extended timeline is that it’ll make the project more expensive. This means more wages, equipment rentals and overhead expenses.

  • Cash flow disputes: Contractors relying on staged payments may struggle with finances if delays prevent certain milestones from being reached.

  • Legal disputes: Delays can lead to disagreements between contractors, subcontractors and clients. In extreme cases, this can escalate and may even result in litigation.

  • Reputation damage: Consistent delays can harm a company’s reputation, making it harder to win work in the future.

  • HMRC risks: Payment disputes and unclear records caused by a project delay can increase the likelihood of HMRC reclassification, especially under CIS. This can result in fines, penalties and significant administrative headaches.


How to handle a construction project delay

While delays may be unavoidable in some cases, effective handling can minimise the damage they may cause. Taking a proactive and structured approach will allow your business to recover any lost time and maintain client trust.

Some things you can do include:

Make fast decisions

Once a delay has been identified, swift decision-making is vital. The longer a decision is deferred, the more the problem compounds. So, whether it is sourcing alternative labour or securing more funding, rapid action can stop a minor setback from becoming a major issue.

Plan correctly

Preventing delays starts with strong planning. Comprehensive project management should include risk assessments, realistic costs and resource allocation strategies. Investing in project planning software or hiring experienced managers can pay off significantly.

Have realistic deadlines

Overly ambitious deadlines can lead to frustration and long delays. Make sure a project is always scheduled with allowances for any unforeseen issues. Having a realistic timeline builds trust with clients and reduces pressure on teams.

Have regular team meetings

Communication is key to identifying and resolving delays quickly. Weekly team meetings can help managers stay updated on progress and address issues before they escalate.

Keep track of progress

Monitoring milestones closely ensures that issues are flagged early. Many companies now use digital tools to track the progress of a project and allocate resources efficiently to mitigate any delays.

Document all aspects of the delay

Detailed records of the course, impact and response to a delay can protect your business from any disputes that may arise as a result. Having documented evidence can support any claims you need to make or defend you against financial or legal repercussions.

Reallocate tasks quickly

If certain aspects of a project become delayed, managers should reassign teams to other areas to make sure work can still progress. This ensures productivity remains as high as possible and avoids idle time at a site.

Reschedule as soon as possible

Once the cause of a delay has been addressed, revising the project schedule is essential. Updating deadlines, communicating changes and setting new milestones will keep the project moving forward and with clarity.
