General Contractor vs Subcontractor
The contractual hierarchy on any construction project—from a three-unit residential build in Saipan to a federal infrastructure contract on Tinian—determines who carries legal liability, who pays whom, and who answers to the owner when work fails. Misreading the boundary between a general contractor (GC) and a subcontractor costs money, triggers compliance failures, and can void bonding arrangements on federal projects. Understanding the structural difference is not a credentialing formality; it is a practical operational requirement.
What a General Contractor Actually Does
A general contractor holds the prime contract directly with the project owner. That single fact drives everything else. The GC is the single point of contractual accountability for the full scope of work, budget, and schedule. According to the U.S. Bureau of Labor Statistics, construction managers and GCs earn a median annual wage of approximately $104,900, reflecting the administrative, financial, and legal burden that position carries.
The GC's core functions include:
- Executing and managing the prime contract with the owner or government agency
- Hiring, directing, and paying licensed subcontractors for specialty scopes
- Procuring materials, permits, and inspections for the full project
- Maintaining site safety compliance as the controlling employer under OSHA construction standards
- Providing performance and payment bonds on federally funded work
On federal projects, the GC operates as the prime contractor under the Federal Acquisition Regulation (FAR), which assigns specific obligations including flow-down clauses—contractual terms the prime must pass down to every subcontractor tier.
What a Subcontractor Actually Does
A subcontractor holds a contract not with the owner but with the GC (or in multi-tier arrangements, with another subcontractor). This is a critical legal distinction. The owner typically has no direct contractual relationship with a sub, which affects payment rights, lien rights, and dispute resolution pathways.
Subcontractors perform discrete scopes of work defined in their subcontract: electrical, HVAC, structural steel, concrete, roofing, or any other specialty. Their obligations run to the GC, not to the owner, unless the subcontract or applicable law says otherwise.
Multi-tier arrangements are common. A mechanical sub might hire a sheet metal fabricator as a sub-subcontractor. Each tier inherits flow-down obligations from the tier above, as required under FAR subpart 44 for federally contracted work.
Legal and Financial Separation: Five Key Differences
| Factor | General Contractor | Subcontractor |
|---|---|---|
| Contract Party | Owner or agency | GC or upper-tier sub |
| Bonding Obligation | Miller Act bond required (federal jobs >$150,000) | Payment bond protects subs |
| Tax Classification | Files as prime | May file as independent contractor |
| OSHA Liability | Controlling employer on site | Can be cited as creating or exposing employer |
| Davis-Bacon Compliance | Directly responsible | Must comply; GC liable for violations |
Bonding Under the Miller Act
On federal construction contracts exceeding $150,000, the GC must furnish both a performance bond and a payment bond under 40 U.S.C. § 3701. The payment bond is specifically designed to protect subcontractors and material suppliers who have no direct contractual relationship with the federal government. A sub who is not paid can make a claim against the GC's payment bond. This is not optional—it is a statutory protection embedded in federal procurement law.
Tax Classification
The IRS applies a behavioral control, financial control, and relationship-of-the-parties test to distinguish independent contractors from employees. Most licensed subcontractors qualify as independent contractors, but a GC who misclassifies workers—treating W-2 employees as 1099 subcontractors—faces back payroll taxes, penalties, and potential DOL enforcement action.
Davis-Bacon Wage Requirements
On federally funded construction, the DOL Wage and Hour Division enforces Davis-Bacon Act prevailing wage requirements. The prime contractor is directly responsible for compliance, but that liability extends to subcontractors at every tier. A sub paying below the applicable wage determination creates an obligation and potential liability that flows back up to the GC. Prevailing wage rates for CNMI federal projects are set by DOL wage determinations specific to American Samoa/Pacific Island classifications.
OSHA's Controlling Employer Doctrine
OSHA's multi-employer citation policy creates four possible employer categories on a job site: creating employer, exposing employer, correcting employer, and controlling employer. A GC almost always qualifies as the controlling employer because it has authority to direct all trades and correct hazardous conditions. That means a GC can be cited for a sub's safety violation even if the GC's own employees were not exposed.
Subcontractors can be cited as creating employers (if they caused the hazard) or exposing employers (if their workers faced the hazard). Running two separate companies does not dissolve OSHA liability—the site is one physical location governed by a unified safety program for which the GC bears primary responsibility.
Joint Employer Risk
The NLRB's joint employer standard holds that two entities may both be considered employers of the same workers if they share or codetermine essential terms and conditions of employment. A GC who exercises direct, immediate control over a subcontractor's workers—setting their schedules, supervising their methods, or controlling their discipline—risks being classified as a joint employer. That classification triggers collective bargaining obligations and unfair labor practice exposure.
Federal Contracting on CNMI Projects
The SBA's federal contracting program recognizes the prime/subcontractor hierarchy in all government contracts, including those executed in the CNMI under federal appropriations. Small business set-aside contracts require the prime to perform at least 15% of the cost of the contract with its own employees on construction projects. Subcontracting plans on larger federal awards must be submitted and approved before award.
