Contractor Qualification Programs
How coating contractor qualification programs such as SSPC-QP 1 and QP 2 work, what owners gain by requiring them, and what contractors should expect from the audit process.
Key takeaways
- Contractor qualification programs evaluate a company — its quality, safety and technical systems — rather than individual workers.
- The best-known coating programs are the SSPC QP series, now administered by AMPP: QP 1 for field work on complex industrial structures, QP 2 for hazardous coating removal and QP 3 for shop painting.
- Owners use qualification requirements to screen bidders before price is considered; contractors use certification to access work that would otherwise be closed to them.
- Qualification raises the floor but does not guarantee a good job. Inspection, a sound specification and a working QC plan are still required.
On a high-value coating project, the owner is trusting a contractor to perform work that will be hidden under the final coat within days. Contractor qualification programs give owners a way to judge, before award, whether a bidder has the systems, people and experience to do that work properly. For contractors, they are both a credential and a management discipline.
Why qualification matters
Low-bid procurement rewards the lowest price among those allowed to bid. If anyone can bid, the lowest number may come from a firm that does not understand the specification or lacks the equipment, training or safety program to carry it out. Qualification requirements narrow the field to firms that have demonstrated basic capability, so price competition happens among comparable bidders.
For contractors, the process of preparing for an audit often improves the business itself: written procedures, training records, equipment maintenance logs and a functioning quality control plan are useful whether or not a client asks for them.
Types of qualification
| Type | Who or what is evaluated | What it demonstrates |
|---|---|---|
| Industry contractor certification (e.g. SSPC/AMPP QP programs) | The company, through document review and field audits | Management, quality, safety and technical systems meet a published standard |
| Manufacturer approved-applicator programs | The company and often its crews, for specific products | Training on and experience with that manufacturer’s systems; often linked to warranties |
| Owner prequalification | The company, against the owner’s own criteria | Safety statistics, insurance, financial strength, references and experience |
| Quality management certification (e.g. ISO 9001) | The company’s quality management system | Documented processes and continual improvement, not coating-specific skill |
| Individual certifications | Workers and inspectors | Personal knowledge and skill, such as applicator or inspector certification |
These layers complement one another. A certified company still depends on trained individuals, and skilled individuals perform best within a company that has sound systems.
How the QP programs work
The QP standards were developed by SSPC, which merged with NACE International to form AMPP; see AMPP, SSPC and NACE explained. Specifications may cite them as SSPC-QP or AMPP QP. The commonly specified programs are:
- QP 1 — contractors performing field surface preparation and coating application on complex industrial and marine structures.
- QP 2 — a supplement for contractors removing hazardous coatings, such as those containing lead, covering containment, worker protection and environmental controls. It is relevant wherever lead paint removal is part of the scope.
- QP 3 — shop painting operations, typically at fabricators and coating shops.
- QP 5 — companies providing coating inspection services rather than application.
In general terms, certification involves documentation of company procedures and records, an evaluation of technical capability, safety and quality systems, and field or shop audits of active work. Certification is maintained through periodic renewal and continuing audits. Exact criteria, categories and fees are set by the program administrator and change over time, so check the current program documents rather than relying on summaries.
Preparing for certification
- Obtain the current standard. Read the program requirements in full and identify which category fits your work.
- Gap assessment. Compare existing procedures, records and training with the requirements and list what is missing.
- Write and implement procedures. Quality control, safety, equipment calibration, training, document control and corrective action — and use them on real jobs.
- Build the record. Auditors look for evidence: inspection reports, calibration certificates, training logs and job files.
- Apply and host audits. Submit the application, then support office and field audits with knowledgeable staff available.
- Close findings and maintain. Address any nonconformances promptly and keep the systems running between audits.
Choose a job with a capable foreman, good access and complete records for the first field audit. Auditors want to see the system working in normal conditions, and a well-run job shows that best.
Requiring qualification in a specification
Owners and specifiers who require qualification should state the requirement clearly in the bid documents and the specification:
- Name the program and category, and whether certification must be held at bid time or at award.
- State how proof is submitted and whether certification must be maintained throughout the work.
- Address subcontractors: if the prime contractor is certified but the coating work is subcontracted, say who must hold the certification.
- Consider whether to allow equivalent qualification and how equivalence will be judged.
Requirements that are too narrow can limit competition and raise prices, especially in regions with few certified firms. Match the requirement to the risk: complex, hazardous or critical work justifies it more than simple, low-consequence painting.
What qualification does not guarantee
Certification shows that a company has systems and has used them successfully. It does not guarantee that every crew on every job follows them, or that the specification is appropriate. Owners still need independent inspection, clear hold points and a contractor QC program that is enforced. Contractors still need supervision that catches problems before they are coated over. Qualification is best viewed as one layer in a system of checks, not a substitute for them.
Frequently asked questions
Is QP certification required by law?
Generally no; it is a contractual requirement set by owners in their bid documents. Some public agencies routinely require it for certain kinds of work, such as bridge painting.
How long does it take to become certified?
It depends on how complete the company’s existing systems are. A firm with documented procedures and good records can move faster than one building them from scratch.
Does manufacturer approval replace QP certification?
No. Manufacturer programs focus on specific products and are often tied to warranties, while QP programs evaluate the contractor’s overall systems. Owners may require either or both.
Do workers also need certification?
Company certification and individual certification are separate. Some specifications require both — for example a QP-certified contractor plus certified applicators or inspectors.
Educational reference. Coating performance varies by formulation. Always follow the manufacturer’s product data sheet, safety data sheet and your project specification.
