worker transfer between construction sites induction evidence

Direct answer. A worker's training, qualifications and experience may be portable, but a suitable induction must address the receiving construction site's actual rules, hazards and controls. Under Great Britain's Construction (Design and Management) Regulations 2015 (CDM 2015), a principal contractor on a multi-contractor project must ensure a suitable site induction is provided and prevent unauthorised access. HSE guidance says every site worker needs a site-specific induction. Before releasing a transferred worker, the receiving team should verify their role-relevant evidence, explain and confirm site-specific arrangements, and make a named access/work decision. Do not mistake a prior site's green status or a generic certificate for authorisation at the new site. CDM 2015 regulation 13; HSE site rules and induction.

This guide is for principal contractors, contractors and workforce coordinators on Great Britain construction projects. It focuses on the *transfer event*: the handover between sites. The existing construction site induction guide owns the broad “what belongs in an induction” question; this page asks which evidence can be reused and what the receiving site must reassess. Northern Ireland has separate construction legislation and is outside this page's legal scope.

Separate portable evidence from site-specific permission

An operator's valid qualification, relevant work-equipment training, professional registration or trade card may remain relevant when they move. That does not prove they know a new site's traffic plan, emergency arrangements, welfare facilities, restricted areas, high-risk interface, permit process or supervisor. The receiving site may also require different equipment or methods from the site they left. The new decision has two parts: can this person safely perform this task? and have they been briefed and authorised for this place and time?

CDM 2015 gives the principal contractor coordination, induction and site-access responsibilities on a project with more than one contractor. HSE says the induction should highlight the particular risks and control measures workers need to know. The contractor employing or engaging the worker also retains duties to provide suitable information, instruction, training and supervision for its work. A principal contractor's induction is not a substitute for the trade contractor's task training, and a contractor's portable training file is not the site's induction. HSE principal contractor roles; HSE site induction guidance.

For a single-contractor project, CDM allocates duties differently: the contractor in control must provide a suitable site induction where one has not already been provided by a principal contractor. Do not assume there is always an appointed principal contractor. CDM 2015 regulation 15.

A receiving-site workflow

1. Identify the person and assigned task. Confirm the worker's name, employer or subcontractor, receiving supervisor, work package, planned dates and the person who has authority to release them. Do not approve “two electricians” as a group without knowing which individuals will attend.

2. Review portable evidence. Check the role-relevant training, cards, licences and authorisations; verify their scope and validity; note anything that expires during the assignment. Do not require every historic certificate if only a subset matters to the job. Where a document appears inconsistent, resolve it before access. An expired certificate decision is its own task; consult a specific owner for that rather than assuming expiry always has one legal outcome.

3. Compare the new task and site. Ask whether the worker will use unfamiliar equipment, take on a new role, use a different method or face a new hazard. Great Britain's Management of Health and Safety at Work Regulations 1999, regulation 13 requires employers to consider capability and train employees exposed to new or increased risks through transfer or changed responsibilities. The proposed role-change competence guide covers that separate decision; only activate the cross-link after integration.

4. Give the site-specific induction. Cover the receiving site's access and egress, traffic routes, emergency signals and muster points, welfare, first aid, site rules, high-risk work controls, relevant live work interfaces, incident reporting and who to contact. Tailor the depth to the actual project and the worker's work. A generic induction slide deck is not enough if it never mentions a material site risk. HSE says a suitable induction must be site specific and highlight relevant particular risks and controls. HSE site rules and induction.

5. Check understanding and any work-specific permission. Use a brief conversation, questions or practical demonstration where suitable. If a task requires a permit, authorisation or supervised first use of plant, handle that separately. An induction record does not itself issue a permit to work, establish specialist competence or lift a restriction in a risk assessment.

6. Record the release. Keep the induction date, version or key topics, person delivering it, worker acknowledgement, any language or accessibility support, outstanding restrictions, receiving supervisor and site/work permission decision. If an issue remains open, state whether the worker may enter only for a limited purpose, work with supervision or not start. Avoid a misleading all-purpose “compliant” badge.

7. Review when the site changes. A transferred worker may return months later after a new phase, changed traffic layout, different emergency arrangements or a changed contractor interface. Use a targeted update or re-induction when the relevant site information has changed; HSE does not prescribe a universal “repeat every X days” interval for this situation. The receiving manager should decide what information the person needs now.

What to hand over from the sending site

The sending team should provide factual worker records, not its own green light as a permanent transferable approval. A useful handover contains identity/worker reference, current employer, completed training and authorisations with scope and dates, any relevant work restrictions communicated through appropriate channels, prior incident or competency concerns that legitimately affect assignment, and the work the person is expected to perform at the new site. Share personal information proportionately and securely.

The receiving site should also know which records it must obtain or verify itself. A passport or right to work file, for example, belongs in a separate immigration-compliance process and should not be copied indiscriminately as part of every site transfer. A contractor can send proof that its worker's role-relevant checks are complete, while the site separately verifies its own induction and access conditions. Legal check ownership varies by relationship; do not conflate it with CDM induction.

Common transfer scenarios

Same worker, same trade, different project. A bricklayer's core competence evidence may remain useful. The new principal contractor still needs to explain the project's actual site rules, welfare, emergency arrangements, vehicle/pedestrian interface and current work-zone hazards, then record the induction. Requiring the same basic external trade course solely because the site changed may add little; failing to brief site hazards is the more serious gap.

Same site, changed phase. A worker moves from groundworks to an occupied-building fit-out. The badge and initial induction may still be valid as records, but the work area, dust controls, emergency arrangements and occupant interfaces may differ. Issue a targeted update and review task-specific capability and controls. A site-specific induction is an ongoing information process, not a once-only paperwork event.

Worker moves into plant operation. A labourer transferred to a new site is now expected to use a machine. Site induction is necessary but not enough. Check task/equipment training, supervision, authorisation and the machine's local safe system before release. HSE's work-equipment training guidance explains why adequate training depends on the task and equipment.

Agency or subcontractor substitution. A contractor says a different worker will attend tomorrow. Reopen the identity, competence and induction decision for the actual person. Do not reuse another worker's record or simply alter a name on an induction certificate. The employer/agency may also have separate right to work duties.

Evidence that helps an audit without creating a duplicate file

Keep a dated record of the specific worker, receiving site, employer, role, portable evidence reviewed, any gap and how it was closed, induction completed, site-specific restrictions, named release decision and relevant changes. Link to the source certificate or training record rather than saving multiple inconsistent copies. Make clear which status belongs to which site and task. This is useful for proving that a decision was made on the actual information available, but a database entry is not itself proof the worker understood an emergency procedure or was competent on a machine.

If a client or inspector asks why someone was working, a good file answers: who was this person, what were they authorised to do, which evidence was checked, what did the new site tell them, who made the decision, and what changed afterwards? It should not require reconstructing a chain of emails and shared-drive folders.

Mistakes to avoid

• Treating the previous site's induction as valid at every later site.
• Requiring fresh generic training while missing the new site's unique hazard or work method.
• Assuming a trade card alone establishes competence for unfamiliar equipment or a changed task.
• Letting a person start because their employer says “approved,” without the receiving site's induction and access decision.
• Applying one site-wide status to all roles, locations and tasks.
• Reusing a previous worker's induction when a substitute attends.
• Assuming a QR or software status, even if live, automatically fulfils CDM duties or the need for human judgement.

Where Complys fits

Complys worker compliance software is a place to evaluate organising workers' training, card and induction evidence across sites. The current marketing page includes stronger passport, QR and ready-status statements whose implementation and release status must be verified before using them as article claims. This guide therefore treats Complys as a possible record-support tool, not an automatic site-access decision maker or legal competence assessor. A principal contractor and each employer still need to perform their own CDM and training responsibilities.

Next step: select the next worker moving between projects. Send the portable evidence early, identify new-site hazards, complete a suitable receiving-site induction and record the named task/site release before the worker starts.
