Key takeaways
- In self perform construction, the contractor runs its own crews and equipment, often through an internal equipment company that rents to its own projects.
- Utilization tells you whether a machine is busy. It does not tell you whether your internal equipment company is earning its place in the business.
- Capture rate divides a project’s spend with your yard by what that project billed the owner.
- Pair capture rate with margin by source, region and project, and you can see revenue and margin move through the whole business.
In self perform construction, every month, equipment dollars leave your projects. Some flow through your yard and come back to the business as revenue and margin. Some go straight to outside suppliers and never show up in the equipment company’s numbers at all. Most contractors cannot tell you the split.
Most self-perform construction companies that run an internal equipment company measure the machines. Time utilization, dollar utilization, hours on the meter. Those numbers matter, and construction equipment utilization is worth tracking well, but they answer a narrow question: is this asset busy? They do not answer the question leadership keeps asking: is the equipment company earning its place in the business?
One number answers that question better than any other. Call it the equipment spend capture rate. If you are not running it every month, you are managing your yard as a cost center, even if the org chart calls it a profit center.
What Is Self Perform Construction?
Self perform construction means a general contractor completes part of the work with its own crews instead of subcontracting it. Concrete, carpentry, structural steel, sitework and electrical are common self-perform trades. Because those crews need equipment every day, a self-performing contractor usually owns a large share of its tools and machines.
Many self-perform contractors run that equipment as its own business unit. The internal equipment company charges projects for what they use, sources what the yard does not carry, and reports revenue and margin like any other division. That is where measurement gets hard, and where most contractors stop at utilization.
Why Revenue Is the Wrong Scoreboard for an Internal Equipment Company
An outside rental company lives and dies on revenue because every dollar comes from a customer who could have gone elsewhere. An internal equipment company is different. Its customers are its own project teams, and its revenue can rise simply because someone raised internal rates. That moves money from one pocket of the company to another. It does not prove the yard created value.
The internal equipment companies that run most like real businesses watch margin first. They track it month over month and are comfortable seeing margin climb in a month when revenue dips. Many also run a separate P&L for each region or location, with shared overhead spread across regions based on each one’s share of total revenue.
That structure creates accountability, but it leaves a blind spot. A region can hit its revenue number and grow margin while project teams quietly send a large share of their equipment spend to outside suppliers. Neither metric shows the work you never saw. Capture rate does.
What Is the Equipment Spend Capture Rate?
Capture rate measures how much of a project’s work flows through your equipment company, relative to the size of the project.
Owner billings are a firm, approved number already in your ERP, and they scale with the real size of the work.
Owner billings make a better denominator than project budget for two reasons. Billings are a firm, approved number that already lives in your ERP. They scale with the real size of the work, so you can compare a $20 million interiors package to a $400 million data center on the same line.
How to Read Capture Rate at Enterprise Scale
There is no published benchmark for capture rate, but the math sets useful guardrails. Industry estimates put equipment at roughly 5 to 10 percent of total project cost. On an enterprise building project, much of that spend belongs to trade partners and general conditions, so a yard that only serves its own self-perform crews will sit near the bottom of the range. Yards that also supply site logistics and the trade partners on the same jobs can capture far more of it.
Going around the yard
The team rents outside, or the scope does not match your inventory.
Core needs covered
Self-perform crews use the yard, but site services and trade partners still go outside.
The yard runs the jobsite
Self-perform crews, site logistics and trade partners all source through the equipment company.
Treat these ranges as illustrative for enterprise general contractors that self-perform core trades such as concrete, carpentry and drywall. Heavy civil and earthwork contractors will run well above them. Set your own baseline from twelve months of history, then watch the spread.
The spread is the real insight. A 4% project and a 1% project with similar scope are not a pricing story. They are a behavior story, and behavior can be managed.
Seeing Revenue and Margin Move Through the Business
Capture rate is the front door. Once you know how much project work flows through the yard, the next question is what that work earns. That means following an equipment dollar all the way through the business, from the request on site to the margin on the equipment company’s P&L.
Margin by source
Owned equipment, re-rents and site services each earn a different margin. Split them to see what really drove a strong month.
Margin by region
A P&L per region, read next to capture rate by region, tells a cost problem apart from a growth problem.
Margin by project
What each job spent with the yard, what the yard earned on it, and what the job spent outside.
Margin by Source
Not every dollar the yard bills carries the same margin. Owned equipment earns the most once it is paid off. Items the yard sources from outside suppliers and re-rents to the project earn only the re-rent markup. Site services and consumables carry margins of their own. When you see revenue and margin split by source, you can tell whether a strong month came from owned inventory working harder or from a spike in re-rents that barely cleared cost. A category you re-rent every month is probably one you should own.
Margin by Region and Location
Contractors that grew by acquisition often run each region as its own company, with different equipment and different processes inside the same parent. A region-level P&L, with shared overhead allocated by each region’s share of revenue, shows which locations are pulling their weight. Paired with capture rate by region, it shows why. A region with thin margin and a high capture rate has a cost problem. A region with healthy margin and a low capture rate has a growth problem, because project work is walking past the yard.
Margin by Project
Project-level numbers close the loop. When every rental, re-rent and charge is tied to the right project, you can see what each job spent with the yard, what the yard earned on it, and what the job spent outside. That is the view that turns a conversation with operations leadership from opinion into evidence.
Revenue tells you activity. Margin tells you value.
Capture rate tells you how much of the opportunity you are actually winning. An internal equipment company that reports all three, by source, region and project, is reporting like a business.
Most contractors can produce one of these views with effort. Very few can produce all three every month without someone rebuilding a spreadsheet, which is why the yard so often gets judged on cost alone.

Four Levers That Raise Capture Rate
Four levers come up again and again among contractors who have pushed capture rate up.
A top-down rent internal first policy
Senior leadership says it plainly: project teams rent from the equipment company. When the yard does not carry an item, it sources it outside and re-rents it to the project. Spend stays visible, and the yard earns a margin on the transaction.
Monthly superintendent meetings
Project teams cannot use what they do not know you have. A standing monthly meeting with superintendents and foremen is the place to show new inventory, new services, capture rate by project, and how to request equipment the right way.
Insource the categories that leak
Every outside rental invoice is a map of where your yard could grow. Site services such as temporary power, lighting, office trailers, restrooms, fencing and scaffolding have become growth lines for internal equipment companies.
Someone who owns the relationship
An outside rental company would never leave its largest customer without an account manager. Some equipment leaders recruit the rental reps their superintendents already trust to carry capture rate and margin results to every project review.
Some of the largest general contractors are taking this a step further, standing up equipment and site services companies that also serve the trade contractors working on their projects. Every trade partner that rents from your yard instead of an outside supplier raises capture rate without adding a single self-perform hour.
When every region is making money in one category, ask why yours is not. A system that shows which categories earn the most in each region tells you where to insource next.
The Data You Need to Run the Number Every Month
Capture rate is simple math. Getting clean inputs is where most contractors stall. You need five things.
- Owner billings by project, from your accounting system or ERP.
- Internal equipment charges by project, including owned equipment and anything the yard re-rented on the project’s behalf.
- Outside rental spend by project, so you can see what leaked and to whom, not just what you captured.
- A clean project structure. When master agreements bundle dozens of small jobs under one project number and a rental gets charged to whichever sub-job still has budget, it lands on the wrong job and your project-level capture rate stops meaning anything.
- Margin by source, category and region, so you can see which lines of business earn and where to insource next.
For most contractors, these inputs live in three or four places: a tool tracking system that knows where assets sit, an ERP that knows what the owner was billed, AP invoices that show outside spend, and a spreadsheet someone rebuilds every month. Tracking tools can tell you where a drill is. They cannot tell you what it earned.
RentalResult runs your internal equipment company as a business system, not a tracking tool. Rental contracts, re-rent purchase orders, workshop orders and transfers can all carry a project code, and transactions can be set to require one, so charges land on the right job. Re-rent uplift can be set by item, project or customer account, so outside sourcing still earns the yard a margin. Rental and re-rent cost postings flow through the general ledger interface to the ERP you already run, with integrations for systems such as SAP, Oracle, CMiC and Vista. Utilization snapshots summarize by day, week or fiscal period and record invoiced revenue alongside contracted and target rates.
The result is that both halves of the capture rate finally sit in the same place. See how construction equipment management software built for self-perform contractors turns a monthly spreadsheet exercise into a number leadership can trust.
Start With One Quarter
You do not need a system change to start. Run this exercise on last quarter.
Ask the top performers what makes the yard easy to use. Ask the bottom performers what they rented outside and why. You will learn more about your equipment company in that one exercise than in a year of utilization reports.
A yard that can prove its capture rate is no longer a cost to defend. It is a business to grow.
