Bookkeeping for Steel Erection Contractors

Steel erection is high-stakes work. Big crews, heavy equipment, expensive materials, and insurance costs that would make most trades flinch. A single crane rental can run more than most contractors spend on materials for an entire job. And if your books don’t separate fabrication costs from erection costs from equipment costs, you’ll never know the true margin on the work you’re putting up.

What Steel Erection Contractors Need From Their Books

Fabrication vs. erection cost separation. If you fabricate and erect, those are two fundamentally different operations with different cost structures. Fabrication is shop-based: cutting, welding, assembly, coatings. Erection is field-based: rigging, cranes, ironworkers, connections. We track them as separate cost centers within each job so you can see the margin on each phase independently.

Crane and equipment rental allocation. Crane costs are one of the biggest line items on a steel erection project. Whether you own the crane or rent it, the cost needs to be allocated to the specific job. We track crane hours, mobilization charges, and operator costs by project so your job cost reports reflect the real equipment burden.

Insurance cost tracking and allocation. Steel erection carries some of the highest insurance rates in construction. General liability, workers’ comp, and builder’s risk premiums are significant expenses that affect your real cost per ton of erected steel. We track insurance as part of your overhead allocation so every bid reflects your true cost of doing business.

Job costing by project phase. Detailing, fabrication, delivery, erection, bolting and connection, touch-up and punch. We set up cost codes for each phase so you can see where the money goes on every job.

Subcontractor and specialty labor management. If you sub out detailing, coatings, or specialty welding, those costs need to be tracked by job and reconciled against your sub contracts.

Equipment depreciation for heavy iron. Cranes, forklifts, welders, torches, rigging equipment. We maintain your fixed asset schedule, coordinate depreciation with your tax strategy, and track equipment costs per job.

The Problems We Solve for Steel Erection Contractors

Steel erection contractors come to us when crane and equipment costs are a black box in their books. When they bid at a healthy margin but the actual numbers tell a different story once the crane hours and insurance are factored in. When their surety is asking for financial statements that show job-level detail and their current books can’t produce them.

We also work with steel contractors who are growing into larger structural projects and need the financial infrastructure to support bigger jobs, longer timelines, and higher bonding requirements.

Common Questions From Steel Erection Contractors

How do you handle crane costs? We track crane costs by job, including rental, mobilization, operator, and fuel. For owned cranes, we calculate a fully loaded hourly rate and allocate it based on job usage. Every job cost report reflects the true crane burden.

Can you handle multi-entity structures? Yes. If you run a separate entity for equipment or fabrication, we manage the intercompany transactions and consolidated reporting.

What about safety and compliance costs? We track safety-related expenses, including training, equipment, and compliance costs, as a defined overhead category. This gives you visibility into safety spending and ensures it’s factored into your overhead rate for bidding.
