SBA loans for other heavy and civil engineering construction

A code for the heavy work that fits nowhere else

Road, utility-line and water-line contractors have their own codes. This one holds the rest of heavy civil work: marine construction such as docks, piers, bulkheads, seawalls and dredging; outdoor recreation construction such as athletic fields, tracks, golf courses and parks; and rail, canal, flood-control and other specialty civil projects. The businesses differ, but lenders meet the same issues in each: project revenue, specialized equipment and a customer list that turns over as jobs finish.

SBA lending to them is sizable. The 198 loans had a median of $250,000 and a middle half from $100,000 to $670,950. The 90th percentile was $1,959,000, and 37 loans, 18.7%, reached $1 million or more. The median rate of 10.13%, with a middle half from 9.25% to 11%, sat just below the national 10.25%. SBA Express, which goes up to $500,000 with a 50% guaranty, carried 40.9% of loans, while start-ups were only 6.6% and franchises 0.5%: lenders here mostly see established operators with a record of completed jobs.

The industry's 30 SBA 504 loans, at a median of $777,000, are notable. A marine contractor needs waterfront with a bulkhead and room to stage barges, and a field or golf contractor needs a yard for equipment and materials. Property like that is hard to find for rent, which pushes owners toward buying. 504 finances owner-occupied real estate, typically 50% from a bank, 40% from the CDC and 10% from the borrower; property with few alternative uses may be treated as special-purpose, raising the borrower's share to 15%. See SBA 7(a) vs 504.

Where the revenue comes from, and how it pays

The customer mix decides the working-capital need and much of the risk. A lender will ask for revenue by customer type over several years, because each type pays differently.

Public and institutional work is usually bonded, and a surety reads the same work-in-progress schedule a lender does. The road and bridge contractor page covers bonding, over- and under-billings and retainage in detail. For the working-capital gap between payroll and payment, contractors usually need a line rather than a term loan: see lines of credit for government contractors and contract financing.

Normalizing a year that was not normal

Heavy specialty contractors have lumpy years, and lenders will not lend on the best one. A hurricane or flood season can fill a marine contractor's schedule with emergency seawall and dock repair for a year or two, then fall away. A single large field or rail project can double revenue in the year it is built. Lenders look at several years, identify what will not recur, and size the loan to the earnings that will.

Take a contractor whose earnings available for debt service were 450, then 700 in a storm-repair year, then 480. A lender will not average in the 700 as if it were repeatable; it will likely underwrite nearer 460. Against proposed payments of 380, that clears SBA's minimum of 1.15x, and 1.0x globally including the owners, but not the 1.25x on historical results that a change of ownership must show from 1 October 2026. The same contractor presenting the storm year as its run rate will lose credibility on the rest of the file. See lending on run-rate EBITDA and EBITDA addbacks.

• Backlog. Signed contracts not yet performed, with expected start dates, are the best evidence of next year. Bids outstanding are not backlog.
• Project concentration. When one job is a large share of a year's revenue, a delay or a dispute on it moves the whole year. See customer concentration and debt.
• Permits and work windows. In-water work often needs federal and state permits and may be limited to environmental work windows. Lenders ask whether backlog is permitted, because an unpermitted job cannot start on schedule.
• Gross margin by job. Profit that fades between bid and completion is the warning sign lenders look for in a job-cost report.

Specialized equipment as collateral

Barges, workboats, crawler cranes, pile-driving rigs, dredges, laser-grading and turf equipment are expensive and essential, and many have a thin resale market. Lenders value them on orderly liquidation value, not replacement cost, and for large requests order an appraisal. A general excavator holds value because many contractors want one; a spud barge or a sand-cap machine may sell slowly and at a deep discount. See equipment appraisals: OLV and FMV.

Vessel collateral works differently from other equipment. A barge or workboat documented with the Coast Guard is secured by a preferred ship mortgage, not only a UCC filing, and a lender will want the vessel documents and existing mortgages identified. Marine contractors also need coverage for maritime workers, under the federal Longshore Act for dock and shore crews or Jones Act liability for vessel crews, plus hull and protection-and-indemnity insurance; lenders ask for all of it.

Most of this equipment is already financed, often by equipment lenders holding a lien on each unit. An SBA 7(a) loan can finance equipment for up to 10 years, or 15 if its useful life supports it, and refinance existing equipment debt only if the new payment is at least 10% lower and the debt has been current for 12 months. See equipment financing vs SBA 7(a) and refinancing equipment loans.

SBA will not refinance an active merchant cash advance. From 1 October 2026 an advance becomes eligible only once converted to a term loan that has amortized for at least 24 months with no new advance since.

Buying a specialty civil contractor

Only 18 loans financed a change of ownership, 9.1% of the total, but their median of $1,802,500 was close to the industry's 90th percentile, at a median rate of 9.88%. A contractor worth buying brings crews who know the work, a fleet, licenses, a bonding history and relationships with the engineers and agencies that award jobs, and buyers pay for all of it.

Much of that value can walk away at closing. A surety bonds the contractor it knows, and after a sale it will underwrite the new owner and the new balance sheet. Agency and engineer relationships sit with the seller. SBA lets the seller consult for up to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026, but not stay on as an owner, officer or employee. Buyers with estimating and project management experience in the same niche fare better. See buyer experience requirements and financing an excavation company acquisition.

The equipment helps with SBA's valuation rule: an independent business valuation is required where the amount financed, less appraised real estate and equipment, exceeds $250,000, so a fleet appraisal reduces the goodwill the valuation has to support. The buyer injects at least 10% of total project costs, with a seller note counting toward half of it only on full standby for the life of the SBA loan, no earnout to the seller, and from 1 October 2026 a quality of earnings report is required on acquisitions of $3 million or more excluding real estate. See SBA's valuation requirement.

Preparing a heavy civil contractor's file

SBA's list is the base: business tax returns for 2–3 years, a P&L and balance sheet with a year-to-date P&L through last month-end, a debt schedule with copies of notes being refinanced, and personal tax returns and a personal financial statement for each owner of 20% or more. An acquisition adds the target's latest full year of figures and the letter of intent.

• A work-in-progress schedule and a backlog report with start dates and permit status
• Revenue by customer type and the largest contracts of each year, with storm or one-off work marked
• Completed-job margins against bid
• An equipment list with vessel documentation, liens and any appraisal
• The surety's current bonding line, and insurance certificates including maritime coverage

Transparent builds that into a full lender package — financing model, lender presentation, blind teaser and underwriting memo — in a day once the documents are in, and places it with the lenders that fit: 278 in its book write SBA 7(a) and 504, and 244 write equipment. On SBA loans the lender pays Transparent, not the borrower. See how we underwrite and the neighboring site preparation and water and sewer line pages.
