Delays and change orders are routine in complex builds, yet many contractors lose rights by treating notice as optional. A disciplined approach begins with understanding the contract's notification windows, whether they are days or business days, and recognizing the critical moment when a change or delay arises. The contract should spell out who must be informed, what facts to include, and the method of delivery. Proper notice isn’t mere formality; it creates a paper trail that supports future claims for extension of time, additional costs, or equitable adjustments. Without timely notice, a party may be deemed to have waived its right to recover or to seek protections against liquidated damages.
To implement a reliable notice process, set up internal checklists that mirror contract requirements and deploy them across project teams. Train field supervisors, project managers, and procurement staff on the exact language required for notices, the deadline calculations, and the preferred delivery channels such as email or certified mail. Maintain centralized records that timestamp every notice and its receipt. Assign a responsible person to review each potential delay or change order, determine whether it triggers a notice event, and confirm whether the timing aligns with the contract’s definitions of time impact. This discipline reduces disagreements when negotiations occur later in the project.
Systematize notices to protect costs, time, and project integrity.
As changes emerge, a contractor should document the scope, basis, cost impact, and anticipated schedule effect before issuing a notice. The notice should reference the specific contract clause, the event that prompted it, and the expected remedy, such as an extension of time or a price adjustment. Clear, concise, and factual language helps owners and sureties evaluate the claim without spin or ambiguity. Proactively outlining the impact on performance milestones creates a constructive dialogue rather than a reactive dispute. When notices are precise and timely, they support enforceable change orders and help preserve access to dispute resolution paths if negotiations stall.

Delays caused by design revisions, field conditions, or late deliverables from subcontractors require careful timing. The notice should capture the change’s origin, the affected work, and the modified sequence or resource plan. Contractors should also attach supporting documents—daily logs, correspondence, revised schedules, and cost estimates—so sponsors can assess the claim with a full understanding of the scenario. A well-crafted notice enables the project team to adapt, reallocate resources, and minimize ripple effects. It also demonstrates the contractor’s intent to cooperate while preserving rights to additional time and costs under the contract.
Capture every event with timely, well-documented notices and cooperation.
When communicating delays, distinguish between excusable delays and those that are at fault. The notice must establish which category applies by referencing the contract’s defined events, such as weather, shortages, or owner-caused changes. By doing so, a contractor preserves the right to a compensable extension and prevents a later claim from being deemed unwarranted. The process should include an initial notice, a detailed subsequent update, and a formal claim if the delay extends beyond the anticipated window. Consistency matters; inconsistent notices undermine credibility and invite disputes. A structured approach reassures owners and lenders that the project remains under careful control.

Change orders require a precise sequence: notification, acknowledgment, scope clarification, and price reconciliation. The initial notice should identify the change’s nature, the expected effects on performance, and the anticipated cost. The contractor should request a formal change order documented by the owner or architect, with an agreed baseline for progress tracking. If the owner disputes the change, the contractor can rely on the notice record to demonstrate timely compliance and to support a claim for adjustment. Maintaining open dialogue through every stage helps prevent claims from becoming legal battles and keeps the project moving forward.
Proactive documentation and clear communication prevent escalation.
Contract language often determines how notices are served—email with read receipts, certified mail, or a project management portal timestamp. Your practice should align with the preferred method in the agreement and any local requirements. Deadlines are typically calculated from receipt rather than dispatch, so confirm delivery and ensure the recipient understands the content. Acknowledging receipt is essential; it confirms that the other party received the notice and can proceed with the intended process, such as issuing a change order or adjusting the schedule. An apparent failure to receive a notice during a critical window can derail a claim, even when the underlying facts support it.
In addition to formal notices, keep transparent communication logs that summarize discussions, decisions, and tentative outcomes. These logs should be accessible to project stakeholders and include references to supporting documents. While formal notices drive legal protections, ongoing dialogue helps resolve issues early and reduce the likelihood of escalation. When team members document conversations, they create a collaborative record that supports negotiation and compromise. This proactive approach can prevent minor misunderstandings from evolving into costly disputes, while still maintaining a robust defense for legitimate time and cost adjustments.

Designate a dedicated administrator to oversee notices and changes.
The project’s risk management plan should feature a dedicated section on notices, change orders, and suspension procedures. It should specify who is authorized to issue notices, how to handle ambiguities, and how to escalate disputes about timing or cost. The plan should also include templates for common notices, with placeholders for dates, descriptions, and dollar figures. Templates help standardize submissions, ensure completeness, and speed up the approval process. A well-designed framework reduces missed notices and supports timely adjustments, which in turn preserves project continuity and protects the contractor’s financial interests.
As part of governance, appoint a contract administrator with the authority to make day-to-day decisions about notices and changes. This role ensures consistency, accountability, and rapid response to emerging issues. The administrator should coordinate across design teams, field operations, and finance to gather the necessary information for a robust notice package. By centralizing control, the project can avoid conflicting messages and inconsistent interpretation of contract terms. The administrator’s leadership also reinforces the expectation that notices will be accurate, timely, and fully documented for audit or dispute resolution purposes.
Finally, maintain a culture of compliance that values notice discipline as part of ethical contracting. Reward timely, correct submissions and visibly address gaps when they occur. Regular audits of notice practices help identify weaknesses, such as missing data, late deliveries, or ambiguous language. Use audit results to improve training, templates, and internal controls. A culture of compliance doesn’t merely avoid penalties; it strengthens professional credibility with clients, lenders, and subcontractors. When all parties understand the importance of proper notices, delays and changes become manageable variables rather than existential threats to a project’s success.
Evergreen lessons emerge from ongoing practice: every delay and every change order demands prompt, precise, and well-supported notices. The core objective is to preserve the right to extend time, adjust price, or secure other contract remedies while maintaining constructive collaboration with owners and architects. By aligning actions with contract provisions, documenting thoroughly, and communicating clearly, contractors can reduce disputes, safeguard margins, and keep projects on track. This disciplined approach becomes a lasting asset—one that elevates professional reputation and contributes to smoother, more predictable project delivery across the industry.
