You’ve returned from official travel—fatigue in your bones, receipts in your pockets, and the quiet hope that your reimbursement will go smoothly. Yet, there it is: the constructed travel worksheet—confusing, technical, and seemingly designed to trip you up.

Sound familiar?

You’re not alone. For federal employees, government contractors, and military travelers, this worksheet is often a source of stress. But here’s something that rarely gets said: once you master this form, you’ll gain control over a critical part of your travel process. No more delays. No more denials. Just faster reimbursements and fewer headaches.

This guide breaks down every step in plain language, so you can confidently complete your worksheet, submit your travel claim, and move on to what truly matters—your mission, your purpose, and your peace of mind.

What Is a Constructed Travel Worksheet, and Why Does It Matter to You?

If you travel for official government purposes, you’ve likely heard the term constructed travel—but what does it actually mean?

Constructed travel occurs when your personal preferences (like a layover to visit family, different departure dates, or an alternate airline) differ from the most direct, government-approved route. Since taxpayers fund federal travel, you’re only reimbursed for what the government would’ve spent had you taken the official route.

That’s where the constructed travel worksheet comes in: it’s your tool to compare actual expenses with authorized costs.

Who Needs This Worksheet?

You’ll be required to complete one if:

• You deviate from your official route
• You combine personal and official travel
• You use non-contract carriers or different lodging
• You book your own travel instead of through a government system (like DTS or E2)

How to Fill Out a Constructed Travel Worksheet (Step-by-Step)

You don’t need to be a financial analyst to complete this form—you just need the right guide. Here’s exactly how to do it.

Step 1: Collect Your Travel Data

Before anything else, gather:

• Constructed route cost (GSA city-pair fare, standard lodging, per diem)
• Actual costs (what you truly paid for airfare, lodging, meals, etc.)
• Travel dates and trip segments
• Receipts (save every one!)
• Documentation for deviations (medical, family emergencies, etc.)

Step 2: Understand the Structure of the Worksheet

Here’s a breakdown of typical sections you’ll find:

Worksheet Section	What to Include	Pro Tip
Constructed Cost	Airfare (GSA rate), gov-approved lodging, per diem	Use GSA City-Pair Search
Actual Cost	Your real airfare, lodging, meals	Include copies of receipts
Difference Summary	Cost variance between actual vs. authorized	Justify overages with memos or email approval
Traveler Justification Notes	Why you chose an alternate route or method	Keep it factual, brief, and specific

Step 3: Provide Solid Justification for Your Choices

Without proper justification, your claim could be reduced or denied.

Use cases that are commonly accepted:

• Personal Convenience: Visiting family or combining personal leave
• Medical or Emergency Need: Unforeseen health or safety circumstances
• Mission Requirement: A change approved by your supervisor or agency

Justify with:

• A short paragraph explaining the change
• Proof (emails, memos, letters, or screenshots)

Step 4: Attach Supporting Documents

You’ll need to back everything up with proof. Attach:

• Official GSA city-pair fare screenshots
• Hotel confirmations
• Airfare receipts
• Booking documentation
• Authorization memos for deviations

Tip: Use PDF or Excel format with clear file names like “Constructed_Fare_Comparison_June.pdf.”

Constructed Travel Worksheet Example

To make this easier, let’s look at a real-world example of how to fill this out:

Segment	Constructed Cost	Actual Cost	Variance
Airfare (GSA Fare)	$350	$480	-$130
Lodging (Standard)	$120/night x 2	$135/night x 2	-$30
Per Diem (Meals)	$70/day x 2	$70/day x 2	$0
Total	$710	$885	-$175

Add your justification: “Traveled via NYC to visit family post-assignment. No impact on mission. All expenses self-funded above constructed cost.”

Avoid These Common Mistakes

Too often, claims are rejected for minor, avoidable reasons. Learn from others’ missteps.

Most Frequent Errors:

• Using estimates instead of GSA-verified constructed costs
• Submitting without receipts
• Forgetting to include a justification memo
• Leaving blanks in the worksheet
• Overstating or rounding up expenses

How to Avoid Them:

• Use GSA.gov for accurate fare data
• Save every receipt
• Double-check every section
• Use concise, professional language in justifications
• Label your files clearly and consistently
