General Building License Used for Engineering-Scope Site Work

The board looks at the nature of the work and whether it is integral to a building or is a separate engineering scope. A general building contractor typically constructs buildings and performs work incidental to the building, such as normal site preparation, foundations, and utility connections that serve the structure. A general engineering contractor typically performs roads, bridges, drainage systems, utility systems, grading, and other horizontal construction. The label used by the county engineer is not controlling; the board examines the plans, specifications, quantities, and whether the work can stand alone as an engineering project. A 300-foot access road and a drainage culvert are classic engineering-scope items. A retaining wall can be either building-related or engineering-related depending on its function, size, and location. Utility trenching may be incidental if it serves the building, but a large separate utility system may require an A or specialty license. The board would also consider whether Koa's own forces performed the work or a properly licensed subcontractor did.

Subcontracting the road and culvert to an A-licensed contractor was a prudent step, but it does not automatically make Koa's entire performance lawful. A B licensee may perform work incidental to the building, and the county engineer's characterization supports Koa on the retaining wall and trenching if those items truly serve the building. However, the board will not rely on the label alone. It will examine the retaining wall's height, location, and structural purpose, the extent of grading, and whether the utility trenching is part of a broader utility system. If the wall is a standalone engineering structure or the grading is substantial site engineering, self-performing it with a B license may exceed Koa's classification. Koa remains responsible for the work even when subcontracted, and it must ensure the A subcontractor's license covers the road and culvert scope. Payroll records will show whether Koa's own employees did disputed work, which is the key facts the board requested.

Koa should have reviewed the plans and specifications before bid and identified which scopes were building-related and which were engineering-related. If the access road, culvert, grading, or utilities were clearly A-scope, Koa should have listed a licensed A subcontractor for all of that work, not just the road and culvert, or formed a properly licensed joint venture with an A contractor. Koa could also have requested a pre-bid clarification from the county and, if necessary, a written determination from the Contractors License Board about the classification of the disputed items. The bid documents and scope breakdown should have matched the license classifications. Koa should not have self-performed ambiguous engineering work and then relied on the county engineer's after-the-fact "incidental" label. A clear scope split, licensed subcontracts, and documented board guidance would have reduced the risk of a protest and a license complaint.
