A civil and site-preparation contractor — grading, excavation, clearing, drainage, paving, and sitework — carries some of the more complex insurance in construction, because the work touches heavy equipment, trucks, deep ground, and often underground utilities. A typical program runs workers' comp, general liability (with the underground exclusion bought back), contractor's equipment, commercial auto, and an umbrella, plus surety bonds for public and larger private jobs. On the workers' comp side, sitework trades rate high — often $6 to $15 per $100 of field payroll before the mod, and higher for deep or utility work. These are general ranges to set expectations, not a quote.
Civil and sitework is where a Southeast project starts — clearing, grubbing, mass grading, cut and fill, drainage, erosion control, and often the paving and utilities that follow. That means dozers, excavators, loaders, and articulated trucks moving dirt near property lines and buried lines, crews in and around open trenches, and haul trucks on public roads. Each of those is a distinct insurance exposure, which is why a real civil program is a coordinated set of policies rather than a single "contractor policy."
Civil work spans several NCCI codes because the crews do different things. Getting each crew into the right code — instead of everything in the highest one — is where most of the savings live.
| Example class code | Type of work | Relative rate level* |
|---|---|---|
| 8810 | Clerical / office / estimating | Lowest — split out |
| 5506 | Street & road — paving / surfacing | Moderate–high |
| 5507 | Street & road — subsurface / bridge & culvert | High |
| 6217 | Excavation & grading, clearing, drainage | High |
| 6229 | Irrigation / drainage construction | High |
| 6306 | Sewer & water main construction | High |
| 7219 / 7228 | Trucking — haul / drivers | Split out separately |
*Directional only. Exact NCCI codes and filed rates depend on your specific operation, carrier, and current filings, and change over time. Confirm your codes with a licensed agent. Not a quote.
The lesson: a civil contractor should never let laborers, equipment operators, and truck drivers all fall into one high code. Drivers and office staff belong in their own lower-rated codes, and the difference across a full season of payroll is real money.
If you read nothing else on this page, read this. The standard commercial general liability form carries the XCU exclusion — explosion, collapse, and underground property damage. Site-work contractors do exactly those things: they trench, bore, grade near structures, and work around buried gas, fiber, water, and electric lines. Cut an unmarked fiber conduit or gas main and the third-party damage can be excluded unless the XCU coverage has been bought back into the policy. The same applies to trench or structure collapse.
This is one of the most common gaps we see when a civil contractor brings in their existing policy for review — a GL that looks fine on the certificate but still has the underground exclusion in place. Confirm XCU is removed, and that any certificate you hand a GC or owner reflects it. A single utility strike can turn an uncovered claim into a six-figure out-of-pocket loss.
Public and larger private civil work almost always requires surety bonds — bid, performance, and payment. DOT, counties, municipalities, and school systems require them on most projects, and many private owners and GCs require them above a contract threshold. Bonding capacity depends on the contractor's financial strength, work-on-hand, and track record, and it's underwritten separately from insurance even though the two are usually arranged together. For a growing civil contractor, bond capacity often decides which jobs you can bid at all, so it's worth building the surety relationship early rather than scrambling at bid time.
Bettr Coverage is an independent commercial insurance agency serving Georgia and the Southeast, and civil and infrastructure construction is a specialty focus. We write workers' comp, general liability with XCU bought back where the work demands it, contractor's equipment, commercial auto, umbrella, and pollution for grading, excavation, sitework, and utility contractors — shopping each account across specialty construction carriers. We work owner-to-owner, we actually check the underground exclusion and equipment schedule most agents skim past, and when a job needs a bid or performance bond we coordinate it through our sister brand BettrBonds.

Sitework rates high — roughly $6–$15 per $100 of field payroll before the mod, higher for deep or utility work. A $500K field payroll might land $30,000–$75,000/yr depending on codes and mod.
Explosion, Collapse, and Underground property damage — excluded on the standard GL form. Site contractors who trench, bore, or work near buried utilities need it bought back, or a utility strike can be uncovered.
Usually yes for public and larger private work — bid, performance, and payment bonds. Capacity depends on financials and track record and is underwritten separately from insurance. Bettr Coverage coordinates them through BettrBonds.
Several — 6217 excavation/grading, 5506/5507 street and road, 6229 drainage, 6306 sewer and water main, plus separate trucking and clerical codes. Splitting crews correctly lowers the bill.
