Power Tool Job Pack Builder

Seven stations compose a provisional generic class and only the calculations your complete entered data can support. Unsupported, unknown and conflicting routes fail closed.

Planning record only. This builder does not select a product, confirm capacity, produce a risk assessment or method statement, or give permission to work. No data is transmitted.

Static seven-station method

  1. Write the task, exact material/subtype, dimensions and quantity.
  2. Stop for suspected asbestos, toxic coating, unknown material, structural uncertainty, reinforcement/post-tensioning or unresolved services.
  3. Find the exact task/material row in the supported map. If there is no exact row or a prerequisite is unknown, write “no automated suggestion” and seek manufacturer/supplier/competent confirmation.
  4. Record the generic class only; obtain the exact machine, accessory, capacity and instructions separately.
  5. Record environment and choose a user-confirmed power path. Use the linked individual worksheet for transformer, generator, lead, battery or compressed air; do not infer missing nameplate values.
  6. Record actual trigger time and representative in-use vibration/noise values. If absent, write “not calculated”.
  7. Record source control, extraction/water, RPE assessment, duration, user-entered quantity and hire dates.
  8. Review every confirmation and stop before signing the worksheet. The worksheet is not a risk assessment, method statement or permission to work.

Supported means provisional

An exact sourced cell can emit a generic class after its branch, subtype, structural, services and specialist screens are answered. Exact machine, capacity, accessory and site controls remain separate confirmations.

Unsupported means no neighbour fallback

No automated suggestion — confirm the method and equipment class with the manufacturer, supplier or a competent person. Unknown, mixed and unlisted inputs never fall through to a nearby row.

Fixed worked example — not worksheet output

Reinforced-concrete core · floor · outdoors

For a 180 × 350 mm wet core after structural, reinforcement and services confirmation: Provisional heavy stand-system wet diamond-coring class. The fixed calculation checks are 2.653 kVA running / 3.183 kVA planned, 200 HAVS points / 3.536 m/s² A(8), 84.98 dB(A) LEX,8h, 9 estimated consumable units and 5 planned calendar days. These are example inputs, not a result for your job.
