Construction Delays: Causes, Claims & Cures
Why “Time Is Money” on Site
Construction projects, much like a carefully orchestrated sequence of events, need to adhere to timelines to ensure success. However, the reality of construction often involves unforeseen circumstances that can lead to delays, sometimes derailing the entire project schedule. While delays might seem like an inevitable part of the process, they frequently escalate into formal claims, particularly when these delays result in added costs and hardships for either the property owner or the contractor. In fact, a significant majority of construction project managers report experiencing delays frequently, highlighting the pervasive nature of this challenge within the industry. This article aims to shed light on the intricacies of construction delays, exploring what constitutes a delay claim, the common reasons behind these delays, the various classifications they fall under, and the critical steps for effective management and mitigation.

What’s a Construction Delay Claim Anyway?
When a construction project’s schedule is extended beyond the agreed-upon timeframe, and a contractor believes they have suffered financial losses as a consequence, they may file a construction delay claim. This formal request for compensation is a crucial mechanism for contractors to document setbacks and seek remedies for damages incurred due to factors that have impeded the project’s progress.
Essentially, a delay claim represents a legal demand made by one party involved in a construction project against another, typically alleging a breach of contract or negligence that has resulted in a delayed completion. The fundamental purpose of such a claim is to seek recompense for the time lost and the additional expenses that have arisen due to the project’s extended duration.
Construction projects are complex undertakings involving numerous stakeholders and intricate processes. Consequently, delays can arise from a multitude of sources. Some of the most common reasons why construction projects experience delays that subsequently lead to claims include:
| Cause of Delay | Typical Excusability | Typical Responsibility |
|---|---|---|
| Severe Weather | ExcusableForce Majeure | Neither |
| Natural Disasters | ExcusableForce Majeure | Neither |
| Labor Shortages | Inexcusable / Excusable | Contractor / Neither |
| Material Shortages | Inexcusable / Excusable | Contractor / Third Party |
| Design Errors/Omissions | Excusable | Owner / Third Party |
| Owner-Initiated Design Changes | Compensable | Owner |
| Equipment Malfunction | Inexcusable / Excusable | Contractor / Neither |
| Permitting Delays | Excusable | Owner / Third Party |
| Financial Issues | Inexcusable | Owner / Contractor |
| Communication Breakdowns | Inexcusable | Owner / Contractor / Third Party |
| Unforeseen Site Conditions | Excusable | Owner |
| Poor Planning/Management | Inexcusable | Contractor |
| Subcontractor Delays | Inexcusable | Contractor |
| Regulatory Agency Actions | Excusable | Third Party |
Excusable delays arise from unforeseen circumstances beyond the contractor’s reasonable control, such as force majeure events (severe weather, natural disasters, war, regulatory actions). These usually entitle the contractor to a time extension.
- Unusually severe weather events
- Natural disasters (earthquakes, floods)
- Hindrances by regulatory agencies or third parties
- Design errors/omissions
- Owner-initiated design changes
Inexcusable delays are caused by factors within the contractor’s control (poor planning, resource issues, late mobilization). The contractor is liable for costs/damages.
- Poor construction quality requiring rework
- Late procurement of supplies
- Inadequate supervision
- Delayed mobilization or submissions
Critical path delays affect activities that directly determine the project’s completion date. Any delay here pushes the entire project back (e.g., foundation work delays).
Non-Critical path delays have float—these can be absorbed without moving the overall completion date (e.g., landscaping work with sufficient buffer).
To claim major damages, a contractor must prove the delay impacted the critical path and completion date.
Compensable delays entitle the contractor to extra payment (and time). These are caused by the owner (scope changes, late approvals, defective plans).
- Owner-initiated changes
- Late approval of drawings
- Failure to give timely site access
- Differing site conditions
Non-Compensable delays grant only a time extension (no extra payment)—often force majeure (e.g., floods).
Concurrent delays happen when two or more independent causes impact the project at the same time (e.g., owner design change + contractor supply delay). Responsibility and compensation get complex: often, neither party recovers damages, but the contractor may get a time extension.
Modern contracts may split or “apportion” responsibility if causes/durations are clearly separated and proven.
The classification of a delay directly shapes the remedies: whether the contractor gets a time extension, compensation, or both. The exact terms in the contract always rule.
In the realm of construction, unforeseen events can throw even the most meticulously planned projects off track. This is where the concept of force majeure comes into play. Force majeure, often translated as “superior force,” refers to extraordinary and unpredictable events beyond the control of the contracting parties that prevent them from fulfilling their contractual obligations. Many construction contracts include force majeure clauses that aim to allocate the risks and responsibilities when such events occur.
Common examples of events typically classified as force majeure include natural disasters such as hurricanes, earthquakes, and floods, as well as pandemics, government actions like shutdowns or new regulations, acts of war or terrorism, and sometimes labor strikes or significant supply chain disruptions.
Natural disasters can have a devastating impact on construction projects, leading to delays due to site damage, material loss, and unsafe working conditions. The economic toll of such events can be substantial, with projects facing delays while rebuilding or restocking, and potentially experiencing price surges in essential construction materials due to increased demand.
Similarly, global events like the COVID-19 pandemic have had profound effects on the construction industry. These events have led to labor shortages as workers fall ill or face quarantine requirements, material escalation due to supply chain disruptions, and the implementation of new safety protocols that can reduce efficiency and increase project costs.
Not always. Whether a pandemic qualifies as force majeure depends on the contract’s specific language and the timing of its execution. If a contract was signed before the pandemic and lists “epidemic” or “pandemic” as a force majeure event, the claim is stronger. If signed after the pandemic’s onset, foreseeability becomes an issue and a claim may be rejected. Always check how your contract defines force majeure events and any exclusions.
Generally, delays resulting from force majeure events are considered excusable, entitling the contractor to an extension of the project timeline. However, whether these delays are also compensable depends on the contract terms. Some contracts may contain “no damages for delay” clauses that could preclude financial compensation even for force majeure. To claim a force majeure delay, the affected party must show the event was truly beyond their control, directly caused the inability to perform, and that reasonable mitigation steps were taken.
The increasing frequency of significant unforeseen events has highlighted the critical importance of carefully drafted force majeure clauses in construction contracts. These clauses need to be specific, clearly define the events covered, and address the implications for both time extensions and financial relief to avoid potential disputes down the line.
- Are force majeure events specifically defined (e.g. pandemic, epidemic, supply chain disruption)?
- Is there a “no damages for delay” clause that limits compensation?
- What are the notice requirements and deadlines for reporting a force majeure event?
- Does the contract require you to mitigate the impact as much as possible?
- How are extensions of time and compensation for additional costs addressed?
Delays in construction projects can often be attributed to the actions or inactions of various parties involved. Understanding who is responsible for a particular delay is crucial for determining entitlement to time extensions and potential compensation.
- Late design changes or scope modifications
- Defective plans/specifications
- Delays in approvals, permits, or site access
- Suspensions of work or late notice to proceed
- Interference or lack of timely decisions
- Financial issues (late payments, lack of funding)
- Poorly written or misunderstood contracts
- Poor quality of work or rework needed
- Late procurement of equipment/materials
- Insufficient supervision or delayed mobilization
- Late submissions (drawings, permits)
- Inadequate planning/resource allocation
- Subcontractor delays
- Regulatory agency delays (approvals, inspections)
- Utility company service delays
- Material supplier failures
- Other contractors working for owner
- Labor strikes (not contractor-caused)
- Land acquisition or statutory clearance delays
Determining the party responsible for a delay often requires a thorough analysis of the contract documents, project schedules, and the specific sequence of events leading to the delay. Clear contractual language that explicitly allocates responsibilities for various potential delays is essential for preventing disputes and ensuring a fair resolution when delays occur.
Construction delays have far-reaching consequences that extend beyond simply pushing back the project’s completion date. These delays can significantly impact a project’s financial health, schedule, and overall success.
- Increased labor costs (including possible overtime)
- Escalated equipment rental and idle equipment costs
- Material price hikes, storage fees, replacement of obsolete/expired materials
- Extended overhead costs (field/home office)
- Liquidated damages (contractual penalties)
- Owner: extra financing, interest, lost revenue/profits
- Other: higher insurance, de/re-mobilization costs
- Critical path delays push back the final date
- Domino effect: each delayed task impacts the next
- May require schedule acceleration/recovery measures
- Revised timelines and milestone adjustments
- Strained relationships between stakeholders
- Potential legal disputes and litigation
- Damage to contractor/project manager reputation
- Client dissatisfaction and lost future business
In the event of a construction delay that leads to a claim, the importance of thorough documentation and evidence cannot be overstated. A well-documented claim provides the necessary support to demonstrate the cause of the delay, its impact on the project schedule, and the resulting financial damages.
