How to Use This Checklist
- Enter the audit context on the checklist: conducted on, prepared by, and location for both office and site audits.
- Work through section 1, Management System, to confirm the system, structure, process groups, management manual, control loop (PDCA) and objectives are known and understood.
- Follow section 2, Own Process (Project / Order), through the sequence from quotation and feasibility review to execution, procurement, project management, documentation, site organisation, measurements, acceptance and archiving.
- Work through section 3, Occupational Safety / Health / Environment, checking that working conditions have been instructed and that safety-related records and site arrangements are in place.
- Answer each question using one of the two scales provided: 100%, 50%, 0%, n.a. or Yes, No, n.a. Use n.a. only where an item genuinely does not apply.
- Log anything that needs correction in the Actions section, with an owner and a due date, and record wider observations in Improvement Suggestions and Notes.

What this audit covers
This checklist supports a comprehensive internal audit for both office and site work, following the 9001, 14001 and 18001 standards. It is built around three areas of investigation: the management system in general, your own process as it applies to a project or order, and occupational safety, health and the environment. There are 100 questions in total, with space for improvement suggestions, notes and actions so that findings can be turned into corrections and improvements rather than left as observations.
Checking the management system in general
The first part of the audit tests whether the system is actually understood and used, not merely written down. You confirm that the management system is known and clearly understood, that the structure and process groups are known, and that the management manual is known. You check that the meaning and purpose of the system are clear, that the internal information platform is in order, that customer satisfaction figures are known, and that the control loop (PDCA) is understood. You also check that the quality management application is known and applied, that your own process (order or project) is known, that organisation and business unit objectives are known, and that information or a presentation was received from the business unit manager.
Auditing your own process (project / order)
The second and largest part of the audit follows a project or order through your defined process. It covers: - **Work execution:** work is carried out according to the defined process, the process specification is known, the team structure is defined and documented, and project risks are identified. - **Quotation:** the quotation is prepared and recorded, recorded in the customer relationship system, reviewed for feasibility, supported by a documented risk analysis, given a quotation number and prepared on the quotation sheet. - **Documentation:** the project or order is documented, and contract checklists, execution documents and a signed order sheet have been applied. - **Contractual basis:** the purchase order, the customer's purchase order, the work contract, the order confirmation and any additional orders or supplements are available and documented. - **Procurement and purchasing:** A-suppliers are preferred, price comparisons and purchasing records are documented, and liability and warranty periods are known and reviewed. - **Project management:** the target specification is defined, project status is known and documented, invoices and progress payments are in order, debtors and open items are in order, and to-do items are in order. - **Documents:** documents are clearly identified, carry the correct date and approval signature, show valid or invalid status, and are traceable and comprehensible. - **Site organisation:** the site folder is available, checklists have been applied and the information board is available. - **Measurements and handover:** measurements are carried out and recorded, the installation indicator or label is available, intermediate inspections are in order, acceptance and handover are in order, and measurement and test records are in order. - **Archiving:** old projects are archived, including completed projects older than one year.
Occupational safety, health and the environment
The third part of the audit addresses occupational safety, health and the environment. It checks that working conditions have been instructed. Alongside this, the site-related checks in the process section — site organisation, the site folder, the information board, measurements, intermediate inspections and acceptance — give you the evidence you need to confirm that safety, health and environmental practice is being followed on site as well as in the office.
Scoring and recording your findings
The checklist provides two assessment scales: 100%, 50%, 0%, n.a. and Yes, No, n.a. Use the scale that suits the question, and reserve n.a. for items that genuinely do not apply. Because the audit covers both office and site, and both system-level and project-level checks, use the context fields — conducted on, prepared by and location — to record where and when each audit took place. Use the Improvement Suggestions and Notes section for anything worth acting on beyond a simple score, and use the Actions section to record what will be corrected, by whom, and by when. Following up those actions is what turns the audit from a snapshot into an improvement.
