The mobilisation has three parts: what the team brings, what the team can demonstrate, and what the site will allow. All three have to be complete before the work begins.

What mobilisation involves before site access

The equipment has to be assembled, checked against the test scope and verified as within calibration. The documentation has to be prepared: procedures, risk assessments, method statements and the test plan.

The access arrangements have to be in place: the induction, the permit to work, the isolation and earthing arrangements and the physical access to the equipment to be tested.

The logistics have to be settled: transport for the equipment, storage on site, a power supply for the test sets and the welfare arrangements for the team over the duration of the work.

Equipment list and transport plan

The transport plan should account for the weight and the number of pieces, the lifting available at both ends and the route into the site. A set that cannot pass through the access route is a set that will be unloaded outside and carried, which takes longer than the test.

Documentation: procedures, risk assessments, permits

The documentation package should contain the test plan with the sequence and the acceptance criteria, the method statements for each test, the risk assessments for the site conditions, and the permits required by the site.

Where the site operates a permit-to-work system, the application has to be made in advance and the permit issued before work starts. The same applies to any isolation or earthing that the site controls.

The documentation should be in the form the site expects. A test plan in the contractor’s own format may be acceptable, and a risk assessment that does not match the site’s template may not, and the difference is discovered at the gate rather than in the office.

The record content that the mobilised team will produce should also be settled in advance, with the acceptance practice that many utilities reference published by NETA and the traceability requirements for the instrument records described in the NIST handbooks.

Team composition and competence records

The team composition has to cover the tests in scope. That means the authorised persons for each method, the supervisor who can authorise energisation and sign the results, and the supporting members who prepare and connect.

The competence records should travel with the team. A site that asks for authorisation evidence and does not receive it may refuse access or restrict the work, and the delay is measured in days.

The composition should also account for the working pattern. A test that requires continuous attendance has a minimum team size, and a programme that runs across shifts needs the competence coverage on each shift rather than across the team as a whole.

Calibration status and instrument verification

Every instrument should be confirmed as within calibration before departure, with the certificate available. On a programme of any length, the instruments whose calibration expires during the work should be identified in advance so that the replacement or the recalibration is arranged rather than discovered on site.

The pre-use check should also be planned: the functional verification that the instrument powers up, responds as expected and, where possible, gives a sensible reading against a known reference. That check belongs in the procedure rather than in the individual’s judgement.

The verification between calibrations should be scheduled for long programmes. A set that is in continuous use for months benefits from a verification partway through, which is also the interval at which a fault is most likely to be caught before it affects a result.

Consumables and spares for the duration

Consumables should be calculated from the number of tests and the duration, with an allowance rather than an exact figure. The calculation should include the items consumed by preparation and by repeat tests, which are the ones that exhaust a stock unexpectedly.

The forgotten items tend to be small: connectors and adapters for specific test points, cleaning materials, earthing leads, labels and the spares for the leads most likely to fail. Each stops work when it runs out, and none is available locally.

The spares should include anything whose lead time exceeds the tolerance of the programme. A consumable that can be obtained locally in a day is not a mobilisation requirement; one that has to be shipped is.

Site induction and access constraints

The induction requirement and its timing should be established before the team travels. Some sites run inductions at fixed times, which can cost a day if the arrival does not coincide with one.

The access constraints follow from the equipment to be tested: which bays are available, when the isolation takes place, whether the work can proceed while adjacent circuits are live, and what the site requires in terms of supervision.

Where the work depends on equipment being made available by another party, the dependency should be named with its date. A test team that arrives to find the equipment not yet isolated has lost the day, and the reason belongs in the mobilisation plan rather than in a post-event discussion.

A mobilisation checklist

The checklist should be of the work rather than of the team, and the first section should be the equipment list, and the second the documentation package, and the third the access arrangements. The remaining sections should cover the team composition and competence records, the calibration status of the instruments, the consumables and spares, and the logistics of transport, storage, power and welfare.

Each section should name the person responsible for confirming it and the date by which it is confirmed. A checklist without owners becomes a document that is filled in after the fact.

The checklist should also identify the dependencies held by other parties, with the date each is required. Those dependencies are the ones most likely to delay the start of work, and naming them is what allows them to be pursued before the team mobilises. Equipment, training and support arrangements that a mobilisation draws on are described under testing services and OEM/ODM solutions; the product range is listed under all electrical testing equipment; the measurement system requirements that the instruments have to satisfy are set out in IEC 60060-2; the safety framework for the work is described by the guidance published by the UK Health and Safety Executive and, for the United States, in the eCFR; comparable project delivery references are listed under typical achievements; and practice is coordinated through CIGRE study committees.
