Contractor Selection and Interface Control
Proportionate prequalification, mobilisation, coordination, monitoring and handover.
How to prepare for an IOSH construction course
Use the developing site scenario to practise proportionate decisions, then confirm the exact assessment and delivery arrangements with your IOSH-approved provider.
Core concepts
Concept 1
Contractor checks should be proportionate to the work and test relevant capability, resources and past performance.
Exam cue: Verify evidence relevant to the actual package.
Concept 2
Mobilisation confirms scope, responsibilities, information, methods, competence and site arrangements before work begins.
Exam cue: Name the owner of each shared hazard and handover.
Concept 3
Managers coordinate simultaneous operations and temporary changes so one contractor does not defeat another's control.
Exam cue: Monitor field performance and correct systemic causes.
Risk pitfalls and guardrails
Selecting solely on generic accreditation or lowest price.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.

Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Leaving isolations, access or housekeeping interfaces implicit.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.

Mobilise Before Motion
Resolve methods, people and interfaces before starting.
One Interface, One Owner
Make coordination responsibility explicit.
Monitor What Happens
Review workface control, not paperwork alone.
Checkpoint rule
