Pre-qualification checklist for contractors, subcontractors and suppliers
Many construction and energy clients will not send you an enquiry until you are pre-qualified. Pre-qualification is mostly paperwork, but missing a single document can cost you a whole project. Prepare this pack once, keep it current, and you can respond to any pre-qualification within days.
1. Legal and company documents
- Commercial registration / trade licence (valid, with permitted activities matching the work).
- Tax registration (VAT or equivalent) and tax clearance certificate where required.
- Chamber of commerce membership and, in some countries, contractor classification or grading certificates.
- Articles of association, ownership structure and authorised signatories (power of attorney).
- Local-content or localisation certificates where the client scores them.
2. Experience and references
- A list of completed projects for the last five to ten years: client, location, scope, contract value, start and finish dates.
- Completion certificates or reference letters for your most relevant jobs.
- A list of ongoing projects with their remaining value – clients use this to judge your spare capacity.
- Photographs and short case studies of two or three projects similar to the one you are bidding for.
3. Financial capacity
- Audited financial statements for the last three years.
- Bank reference letter and evidence of credit or guarantee facilities.
- Average annual turnover – many tenders set a minimum, often a multiple of the contract's yearly value.
4. Quality, health, safety and environment
- ISO 9001 quality management certificate and your quality manual or project quality plan template.
- ISO 45001 occupational health and safety and ISO 14001 environmental certificates, if you hold them.
- HSE policy, organisation chart and statistics for recent years (man-hours worked, lost-time injuries, frequency rates).
- Sample method statements and risk assessments for your main activities.
5. People and resources
- Organisation chart and CVs of key staff (project manager, engineers, HSE and QA/QC leads).
- Workforce numbers by trade and nationality where relevant.
- Owned and rented plant and equipment list, with capacities and age.
- Workshop or factory details, production capacity and certifications for fabricators and manufacturers.
6. Technical evidence for suppliers
- Product catalogues and data sheets.
- Type-test certificates, third-party approvals and country-of-origin documents.
- Manufacturer authorisation letters if you are a distributor.
- Warranty terms and after-sales support arrangements.
7. Insurance
- Third-party liability, employer's liability / workers' compensation and, for designers, professional indemnity.
Tips that save time
Keep everything in one folder with expiry dates in a spreadsheet, so nothing lapses during a tender. Prepare a two-page summary profile and a full pack; send the summary first. Tailor the reference list to each client's sector – a hospital client wants to see hospitals. Finally, answer every question in the client's form even if the information is elsewhere in your pack: evaluators score the form, not your brochure.
Once you are ready, browse open pre-qualifications and expressions of interest, or read our glossary of tender terms.
