Extension of Time: How Contractors Can Survive Delays and Fight Off Penalties

As a contractor, few things are more frustrating than a project running past its deadline. But when a delay happens, it isn’t just about missed schedules—it becomes a high-stakes financial battle. 

Suddenly, you are faced with a double whammy: you are spending extra money keeping your staff and equipment on-site, while the project owner is threatening you with Liquidated Damages (LDs)—the corporate word for penalties. 

To protect your business, you need to understand exactly how the project timeline is legally adjusted, who holds the cards, and how you can get paid for the extra time.

The Three Types of Delays (And Who Pays)

When a project goes over schedule, the Contract Administrator (the Architect, Engineer, or Project Manager) will investigate the cause. Legally, every delay falls into one of three buckets: 

1. Owner-Caused Delays (Time + Money for You): If the owner hands over the site late, delays drawing approvals, or orders major changes, they cannot penalize you. In fact, you are entitled to a formal Extension of Time (EOT), and you can claim your extended head office expenses using standard formulas like the Hudson or Emden Formula. 
2. Neutral Delays (Time Only): If the project is halted by exceptional weather, floods, or sudden labor strikes, it is nobody’s fault. You will be granted an EOT to protect you from penalties, but you cannot claim extra money from the owner. 
3. Contractor-Caused Delays (Penalties for You): If the delay happened because you mobilized late, managed subcontractors poorly, or faced internal labor shortages, the owner has the right to enforce Liquidated Damages. They will deduct a fixed percentage (e.g., 0.05% per day) directly from your monthly bills.

Who Decides the Fate of the Deadline?

The project timeline isn't arbitrary. The owner cannot simply wake up and declare you are late. 

• The Baseline: The "Original Completion Period" is fixed the day you sign the contract. 
• The Judge: During execution, the Engineer or Contract Administrator acts as an independent judge. They are contractually obligated to evaluate delay claims fairly. If you prove the owner caused a hitch, the Engineer is legally bound to push the official completion date forward.

3 Golden Rules for Contractors to Protect Themselves

If you want to win an EOT and claim your overhead costs, courts and arbitrators look for proof, not guesswork. Follow these rules on every project: 

• Rule 1: Document Everything Daily. If an owner verbally tells you to hold off on a section of the site, do not just agree. Send a written email or entry in the site measurement book that same day confirming the conversation. 
• Rule 2: Give Immediate Notice. Most contracts have a strict "Notice Period" (often 14 to 28 days). If the owner delays a drawing, you must formally write to them stating that this event will cause a project delay. If you miss this window, you may legally forfeit your right to an extension. 
• Rule 3: Update your Schedule. Keep a record of your original project plan versus actual progress. Show exactly how the owner's delay disrupted your critical path. 

Summary

Maintain a Site Diary/ Daily Log from Day One. Record all important details without fail.

An Extension of Time is your shield against unfair penalties, and formulas like Hudson are your sword to win back lost overhead expenses. Don't let owners bully you into penalties for delays they caused. Keep your paperwork airtight, issue your notices on time, and know your contractual rights!
