You're staring at a stack of compliance paperwork or maybe a historical real estate audit and you see it: brick schedule 1. It sounds like something out of a masonry textbook or perhaps a very boring Tetris sequel. But in the world of federal procurement, historical infrastructure, and specialized material sourcing, it’s a specific designation that confuses almost everyone who runs into it.
Most people assume it's just a list of red blocks. It's not.
Actually, when we talk about what to do with brick schedule 1, we are usually diving into the weeds of the Federal Supply Schedule (FSS) or specific regional building codes that have grandfathered in older terminology. If you’ve found yourself responsible for managing, disposing of, or sourcing materials under this classification, you can’t just wing it. You need to know if you're dealing with a legacy government contract requirement or a modern architectural standard.
The Reality of Brick Schedule 1
So, what is it? Historically, "Schedule 1" in various industrial and governmental contexts refers to the highest tier of priority or the most basic, foundational list of approved materials. In the context of "bricks," this often points back to the General Services Administration (GSA) schedules or specific state-level procurement lists that dictate what kind of masonry can be used in public works.
Think about a post office built in 1950. Or a federal courthouse. Those buildings weren't just made with "whatever was on sale at Home Depot." They followed a rigorous procurement schedule.
If you are a contractor today and your bid documents mention this, you're likely looking at a requirement for Standard Grade or Severe Weathering (SW) bricks that meet ASTM C62 or C216 standards. But the "Schedule 1" nomenclature is often a holdover from older filing systems. You have to be careful. If you buy "Schedule 2" or "utility grade" when the contract demands the top-tier durability of Schedule 1, your inspector is going to have a field day. And not the good kind.
Identifying Your Specific Materials
Before you do anything, you’ve got to verify the physical properties. Bricks aren't just clay and fire. They are chemistry.
- Check the Compressive Strength: Schedule 1 bricks generally require a high PSI rating, often exceeding 3,000 pounds per square inch.
- Absorption Limits: If these are for exterior use, they need to resist water. High-grade bricks have low absorption rates (usually under 17% for some classifications).
- Color Uniformity: Older schedules were obsessed with aesthetics. If you’re doing a patch job on a historical building, "Schedule 1" might actually be a code for a specific shade of "Chesapeake Red" that hasn't been manufactured since the Carter administration.
I've seen guys try to match 40-year-old Schedule 1 bricks with modern modular bricks. It looks terrible. The dimensions are off by just enough—maybe an eighth of an inch—to ruin the mortar line.

Honestly, the first thing you should do is take a sample to a specialized masonry yard. Don't go to a big-box retailer. They won't know what you're talking about. You need a guy named "Murph" who has been smelling kiln dust since 1984. He’ll tell you exactly what that brick is.
Logistics and Compliance: What to Do With Your Surplus
Maybe you aren't building. Maybe you've inherited a pallet of these things and you're wondering if they're worth more than their weight in literal dirt.
If you have genuine, certified Schedule 1 bricks from a decommissioned federal project, they have value. But there’s a catch.
Resale and Reclamation
Reclaimed bricks are a massive market. Architects love them for that "industrial chic" look. However, if they are "Schedule 1," they are often structurally superior to the cheap stuff made today. You can sell these to specialized architectural salvage yards.
Testing for Hazards
Wait. Stop. Before you start grinding or cutting old bricks, you need to consider lead paint or asbestos-contaminated mortar. If these bricks came from an industrial site or a pre-1970s government facility, they might be "hot."
You don't want to be the person who turned a pallet of bricks into a Hazmat situation in your backyard. Get a lead test kit. It costs twenty bucks and saves you a lifetime of lung issues.
Handling the Paperwork Trail
For those of you in business or government contracting, "what to do with brick schedule 1" is a question of auditing. If these are listed on a property disposal manifest, you have to follow the trail.
- Verify the NSN: If there is a National Stock Number (NSN) attached, look it up in the FedLog system.
- Check for Restricted Use: Some government-sourced materials have "end-use" certificates. You can't just sell them on eBay if they were part of a sensitive facility project.
- Document the Weight: If you're disposing of them, get a weight ticket. Masonry is heavy, and tipping fees are calculated by the ton.
It’s easy to get frustrated with the bureaucracy. Trust me, I get it. But "Schedule 1" usually implies that someone, somewhere, once cared deeply about the quality of that specific clay.

Common Misconceptions About Masonry Schedules
A lot of people think "Schedule 1" means "the first bricks ever made." No. That's not how it works.
In the GSA world, schedules are updated. What was Schedule 1 in 1990 might be under a completely different category today. You have to look at the Effective Date on your documentation. If your paperwork is from the 80s, you are looking at a different set of standards than a 2026 procurement guide.
Also, don't confuse this with "Schedule 40" or "Schedule 80." That's for pipes. If you ask a supplier for Schedule 40 bricks, they will laugh at you. Or they'll sell you a very expensive piece of PVC and wonder why you're trying to build a wall with it.
How to Source Replacements
If you're trying to find more brick schedule 1 to finish a job, you’re in for a bit of a hunt. Since many of these specific schedules have been absorbed into broader ASTM standards, you need to look for "Matching Services."
Companies like Belden Brick or Glen-Gery often have "legacy" lines. You send them a chunk of your existing brick—about the size of a pack of cards—and they use a spectrophotometer to match the color and a lab to match the texture. It’s not cheap. But if you're working on a protected historical site, it's your only option.
Practical Steps for Management
If you have these bricks right now, here is exactly what you should do:
- Photograph the markings: Look for "frogs" (the indentations on the top). Often, the manufacturer's name is stamped right there. This is your "Rosetta Stone" for finding out what schedule it originally fell under.
- Check the "Ring": Tap two bricks together. A high-quality, Schedule 1 level brick will have a clear, metallic "clink." A dull thud means the brick is "soft" or "under-fired," which means it likely doesn't meet the high-durability standards of Schedule 1.
- Verify the Quantity: If you have less than a pallet (about 500 bricks), it’s a hobby project. If you have ten pallets, you have a commercial asset.
Bricks are surprisingly regional. A Schedule 1 brick in Pennsylvania is made of different clay than one in Texas. The "Schedule" was meant to standardize the performance, not the ingredient.

Storage Matters More Than You Think
If you're holding onto these for a future project, don't just leave them in the mud.
Even though they are "Severe Weather" rated, "Schedule 1" bricks can suffer from efflorescence—that white, powdery salt that creeps out of the pores—if they sit in standing water. Keep them on pallets. Wrap them in plastic, but leave the bottom open so they can breathe.
There's nothing worse than finally finding the perfect matching brick only to realize they've all turned white because you left them in a puddle for three years.
Moving Forward with Your Project
Ultimately, dealing with brick schedule 1 requires a mix of historical detective work and modern engineering. It’s about respecting the standard that was set when the building was first conceived.
Whether you are disposing of surplus, sourcing a match for a restoration, or trying to clear a line item on a government audit, the key is documentation. Find the original spec sheet if you can. If you can't, use the ASTM equivalents to prove that your modern materials meet or exceed the old Schedule 1 requirements.
Actionable Next Steps:
- Locate the Original Spec: Check the "Project Manual" or "Division 4" of the original construction documents for the specific ASTM equivalent to the Schedule 1 designation.
- Perform a Water Drop Test: Drop a tablespoon of water on the brick. If it disappears instantly, you have a porous, low-grade brick that likely doesn't meet Schedule 1 standards. If it beads or sinks in slowly, you've got the high-density stuff.
- Contact a Forensic Architect: If the project involves a historic federal building, don't make a move without a professional who specializes in masonry "petrography"—the microscopic examination of stone and brick.
- Calculate Total Tonnage: For disposal, multiply the number of bricks by 4.5 pounds (the average weight of a standard red brick) to get an accurate estimate for hauling costs.
Don't let the "Schedule 1" label intimidate you. It’s just a way of saying "this stuff was built to last." Treat it with that level of respect, and your masonry work—or your audit—will hold up for the next fifty years.
