Construction Delays: Breaking Down the Definitions, Claims, and Mitigation Strategies

As new projects increase in size and complexity, the scenarios that lead to construction delays have become varied and multiple. Strategies have evolved to plan for the inevitable, but it is also important to combine commonsense practices and construction software solutions to reduce avoidable delays. Let’s get to the bottom of how construction delays come about, the impact they have on builds, and what to do about them.

Key Takeaways:

• Construction delays are extensions or interruptions that prevent work from being completed on time, caused by a variety of material, environmental, and interpersonal factors.
• While drawing interpretation issues, safety violations, inadequate resource planning, and subcontractor delays can be attributed to the contractor, clients are often responsible for the approval lags, late design changes, and funding issues that lead to delays.
• The consequences of delays include financial losses, strained relationships, potential legal complications, and reputational damage.
• Delays in construction are classified based on their criticality, responsibility, compensation structure, and other standard factors used to divide these issues into assignable categories.
•  Legal options for delays are based on timing, circumstances, and contract terms, and help to define who is responsible for any additional costs and necessary rework activities.
• Time management skills, clear lines of communication, contingency planning and the use of construction software tools are among the practices recommended to reduce the frequency and duration of delays.

What Are Construction Delays?

Construction delays are extensions or interruptions in project schedules that prevent work from being completed on time. Project delays can be caused by various factors, including weather, material shortages, and disputes between stakeholders and workers.

Delays are almost inevitable, and while many are caused by uncontrollable forces with no one to blame, there can still be significant financial and legal fallout when planned deadlines and budgets are not met.

Top Reasons for Construction Delays

Weather events, natural disasters, vandalism, and other unforeseen issues can certainly lead to project schedule setbacks, but many types of construction delays are directly attributable to either the contractor or the client. This is an important distinction since the potential for financial repercussions may boil down to accountability. Delays that are typically originate with the contractor include:

• Drawing misinterpretation and mistakes: These can trigger a flood of requests for information (RFIs) leading to delays in construction projects while they are resolved, or worse yet, when incorrect interpretations require time-consuming rework to correct.
• Safety violations or accidents: Each safety incident or accident brings the entire construction process to a halt until a thorough investigation can be completed, and corrective actions are implemented.
• Inadequate resource planning: Material and labor shortages can lead to delays when mistakes are made in resource planning, or material delivery schedules and labor assignments. Overallocation can also lead to delays in construction when budgets are depleted and tasks must be re-evaluated.
• Communication lags between independent teams: The contractor should focus on facilitating communication between specialists to avoid bottlenecks, confusion, and avoidable schedule conflicts.
• Subcontractor delays: Poor vetting and tracking processes can stall progress when unqualified teams must be replaced, or poor workmanship creates an unexpected need for rework during the later stages of the project.

On other occasions, it’s the client that makes decisions or initiates changes that can significantly impact the schedule. Examples include:

• Late design changes: Most design changes are requested during the early stages of a project, but late requests changes can lead to delays based on drawing updates, material procurement, and resource management issues.
• Approvals for contract document updates: Slow approval of construction contingencies and other project documents often leads to delays, since work cannot proceed without the proper approvals in place.
• Contract disputes that lead to work stoppages: Disagreements over scope changes, timelines, defective work claims, and other contract issues can prevent tasks from proceeding on schedule.
• Delays in funding: When agreed-upon payments to contractors and suppliers are not completed on time, this can lead to delayed deliveries and work interruptions.  
• Unanticipated site access issues: Environmental regulations, zoning issues, and security problems are among the issues both clients and contractors must resolve to prevent site access from causing project delays in construction.

Consequences of Delays in Construction Projects

It helps clients, contractors, and other stakeholders to be aware of the sources and types of construction delays, so they can handle the potential consequences. While most of the focus is placed on the schedule and financial impact, delays also pose a threat to the reputation and success of all team members.

Consequences for contractors

Delays can lead to unexpected increases in labor, equipment, and material costs, as well as storage fees and administrative expenses. Depending on the contract structure, the contractor could be subject to financial penalties if deadlines are missed, which puts a strain on client relationships.

Construction delay claims can damage a contractor’s reputation for reliability and embroil them in legal disputes that take time and attention away from future projects. Contractors might also experience conflicts with subcontractors over payments, responsibility for rework completion, and overlapping time commitments.

Consequences for clients

Delays are equally stressful for clients, potentially disrupting carefully planned budgets and financing agreements. There may be additional out-of-pocket expenses and accrued interest required to bridge the gaps created by extended timelines. There’s a potential for revenue loss to consider when buildings go into operation later than expected.

Clients are not immune to the domino effect impacting contractors and subcontractors of one delayed project impacting the start of the next. This adds financial strain and may lead to more disputes in construction, especially when the responsibilities for overruns, rework, and scope changes are not clearly defined in the project contract.

Types of Construction Delays

Construction project delays are so common that classification systems have evolved to characterize each claim and assess its impact. The logic used to classify the types of delays in construction projects follows three tiers that filter into assignable categories.

Critical vs. non-critical

A critical delay directly impacts the project completion date and cannot be recovered. One example is a failure to obtain necessary permits, which pushes out the project start date by several months.

By contrast, a non-critical delay impacts the completion of specific activities that are not on the critical path, meaning the lost time can be made up without impacting the overall schedule. An example would be the re-trimming of a building interior, which is done in parallel with other finishing processes.

Excusable vs. inexcusable

As the name implies, an excusable delay is one over which the contractor has little or no control and is therefore not responsible for the financial fallout. This category includes circumstances entirely out of the contractor’s hands, like vandalism and major weather events or minor errors and omissions that are to be expected.

Inexcusable delays point directly to the contractor with no plausible reason or explanation. An example of an inexcusable delay is the hiring of unqualified subcontractors – without proper vetting or license reviews by the general contractor – who then performs work incorrectly.

Compensable vs. non-compensable

Compensable delays happen when the impacted party will be given more time or resources to complete their tasks. Excusable delays are almost always considered compensable, making the previous distinction important. A major weather event would certainly be compensable, while delays caused by mistakes or mismanagement by the contractor are likely non-compensable.

Legal Options for Construction Delay Claims

Once the type of delay has been properly assigned, the issue can be assessed from a legal perspective to determine if it represents a breach of contract or merits some other legal or financial action. This can result in one of several different courses of action.

1. Concurrent delay

A concurrent delay occurs at the same time as another setback, such as a material shortage overlapping a labor dispute. Concurrent delays also define other circumstances beyond the control of contractors, such as waiting for a previous contractor to complete their work or vacate the site. In either circumstance, valid concurrent construction delay claims are usually considered compensable.

2. No damages for delay

This type of clause in a construction contract is used to protect the owner or client from additional charges by the contractor based on excusable delays. This includes delays caused by the client or any other external factors. A ‘No damages’ clause provides contractors with more time, but not more money, to complete their assignments.

3. Improper notice

This category of delay claims in construction refers to situations where delays are encountered, but the client is not notified in a timely manner. These cases can be difficult to resolve if the notification type(s) and time limits are not clearly stated in the contract. For contractors, it is always advisable to err on the side of caution and notify clients of any construction schedule delays immediately while providing documented evidence to explain the reasons for the setback.

4. Time is of the essence

This clause runs somewhat counter to the trend of delays in construction being the norm rather than the exception. With a ‘time is of the essence’ clause in place, no delay is considered either excusable or compensable, and the contractor may be considered in breach of the contract if their tasks are not completed by the original deadline. The likelihood of delays in construction projects obviously makes this clause unfavorable to contractors.

5. Force majeure

A force majeure clause in a contract frees both parties from financial obligation when an event such as a hurricane, fire, war, or pandemic impacts the schedule or prevents either party from fulfilling their obligations. To qualify under this designation, the critical and excusable delay must have been unforeseen, making it impossible to complete tasks on schedule.

How to Manage Construction Delays: Top Tips & Best Practices

For every force majeure driving up costs and pushing out completion dates, many other causes of construction delays are entirely avoidable with the right strategies, tools, and processes in place.   

1. Manage and Plan Time Efficiently

Many project delays are simply the result of poor planning and schedule management. Among the tactics that prevent unrealistic or overly aggressive schedules from turning into delays, it’s advisable to evaluate resource availability carefully, buffer schedules to allow for some level of unforeseen circumstances, and to regularly track progress.

2. Communicate Clearly among Parties

Poor communication on the job site can lead to everything from errors and rework to construction hazards and conflicting subcontractor schedules. Transparent communication channels keep misunderstandings and incomplete information from holding up progress.

3. Show Flexibility and Understanding

It’s more effective to take a proactive approach to delay analysis that emphasizes collaboration and logic over finger-pointing and emotional responses in the effort to avoid delays and limit their impact when they occur. Construction analytics are a useful tool for stakeholders to exchange ideas and solutions.

4. Do Contingency Planning

Construction contingencies are pre-established sums of money, based on a percentage of the overall budget, set aside to cover unforeseen circumstances. Well-planned and adequate contingencies soften the impact of delays by helping projects adapt to unplanned events with minimal schedule impact.

5. Perform Accurate Estimates and Takeoffs

When materials, labor, and other resources (and their costs) are projected accurately in the project’s early stages, it helps prevent delays caused by downstream shortages. Software-based quantity takeoff and estimation methods keep all information up to date to avoid cash flow issues later on or long waiting times for additional materials.

6. Manage Risks Effectively

Construction risk management practices begin with a thorough assessment of all project risk factors, including schedule constraints, environmental issues, and design complexity. Many of these risk factors can lead directly to construction delays if not addressed. Prioritizing these issues via effective risk management helps minimize their impact.

7. Build Supplier Partnerships

Suppliers play a key role in managing project delays – missed shipments, incorrect materials, or poor material quality can easily derail project schedules. Strong supplier partnerships and construction procurement strategies help minimize the frequency and impact of material-related issues by improving response times and allowing for collaborative problem-solving.

8. Utilize Software Tools

Software for schedule management, project tracking, takeoff and estimation, and procurement provide the visibility and reporting capabilities needed to keep setbacks to a minimum while providing an effective forum for stakeholder collaboration. BIM management software also improves outcomes by capturing issues like clashes or design weaknesses in the virtual realm.

9. Secure Permits Early

Obtaining the building permits and inspections required to begin construction can be time-consuming. So, it’s best to apply for all required permits as early as possible. This provides additional time to address issues that come up during the application process, such as documentation gaps, new regulations, or processing backlogs. 

10. Conduct thorough Design Reviews

Few projects or products are more complex than modern buildings and infrastructure construction – it needs enough time to be set aside for thorough cross-functional design reviews and discussions. This allows the team to identify and correct design flaws while clarifying drawings and specifications to prevent costly and time-consuming rework.

11. Utilize Automated Resource Management

Ensure that the right materials, labor, and equipment are available precisely when needed. With so many moving pieces on complex jobsites, this task can be challenging. Software tools that automate resource allocation and analysis activities, along with the stakeholder approvals and notifications help focus attention correctly to avoid those construction delays.

12. Emphasize Quality Assurance and Control

Construction quality management is about setting appropriate material and workmanship standards, then verifying they are being met consistently. Taking QA and QC steps also prevent delays in construction by catching issues before they escalate, and establishing monitoring systems and corrective actions to ensure quality problems are contained or eliminated.

13. Learn from the Past

When a new team wants to learn how to avoid delays in construction projects, a review of past projects is a great place to start. This includes any delays caused by specific suppliers and subcontractors, as well as problems related to building methods, site conditions, or complex features that are likely to recur on future projects unless they are addressed in advance. 

FAQs: Construction Delays

Given the common occurrence of construction delays, it is hardly surprising that professionals around the world would raise the same issues. Let’s address their most frequently asked questions:

How does poor scheduling contribute to delays?

Poor scheduling is one of the leading causes of project delays in construction, since it can impact estimation, resource management, and task assignments with the combined effect of limiting progress while increasing project costs. When schedules are overly optimistic and don’t fully account for the complexity of tasks, this leads to scope creep and delays when activities are not completed on time.

Scheduling issues can also lead to insufficient crew sizes, material shortages, and equipment availability issues that slow down task completion. An accurate schedule is needed to complete proper estimation, procurement, and planning activities for each task. Failing to add contingencies or buffers to the schedule is another common mistake that can cause the completion deadline to be missed based on a series of minor setbacks.

What should be included in a delay mitigation plan?

Construction delay analysis precludes the creation of a delay mitigation plan, which is a written document created during the preconstruction phase to define potential delay types and establish workflows that will lessen their frequency and severity. 

An effective delay mitigation plan includes general information about the project, timeline, and deliverables, a discussion of risk factors that might cause delays, contingency plans based on the identified risks, and instructions on how delays should be classified as excusable or non-excusable, depending on the circumstances. The plan should also define the lines of communication between team members to accelerate decision-making and problem resolution, along with any schedule monitoring and early warning systems put in place to mitigate delays.  

How does poor communication contribute to delays?

Poor communication is another leading cause of delays in construction – it can lead to confusion, delayed information flows, and misaligned expectations, all of which can eventually lead to mistakes or unnecessary work or rework to undo. This includes issues with verbal communication as well as written instructions and specifications.  

Most contractors and workers are accustomed to communicating with a combination of emails, texts, phone calls, and verbal instructions, but this creates clutter. Construction software tools can be useful in clearing the communication clutter and establishing a single source of project truth.

How can BIM and digital construction tools help reduce delays?

The building information modeling (BIM) process moves design, schedule, cost, material, and sustainability information into the digital realm, creating a centralized platform for enhanced collaboration before, during, and after construction. BIM can help prevent or reduce delays by eliminating communication lag, detecting design problems and clashes early, and streamlining scheduling and change management processes.

Other digital construction tools like specification writing, cost estimation, resource management, and construction planning software, also reduce delays by eliminating manual processes and errors while providing real-time project visibility to all stakeholders. Advanced software tools can identify bottlenecks and resource issues automatically, so their impact can be minimized.  

What is a reasonable delay buffer in project scheduling?

The use of delay buffers is somewhat controversial and viewed by some as a crutch that can cause teams to work less efficiently, because they know a buffer is available to pick up the slack. In any event, most construction professionals recommend a buffer of between 5% and 20% of the total project duration, depending on its complexity, risk factors, and historical data. For example, a low-risk activity with an experienced team and similar projects providing historical information might call for a 5% buffer, while a complex project using newly developed materials and methods might increase this to 20% or more.
