Preparation guide

Prepare a plant shutdown around a clear scope

A starting checklist for organizing information, interfaces and decisions before the work window.

Industrial team coordinating a plant-shutdown work sequence

Limited time makes preparation visible

Groupe Tremblay approaches plant shutdowns as interventions where time is limited. That constraint does not define the assignment by itself. Before a team mobilizes, expected work, responsibilities, access, dependencies and conditions for starting all need to be established.

This guide supports an initial discussion. It does not replace the plant's shutdown plan, risk assessment, facility procedures or approved work methods.

Describe the required outcome

Begin with what needs to be available, replaced, repaired, maintained or inspected at the end of the intervention. Separate mandatory work from conditional tasks and desired improvements.

For each work package, identify the equipment or area, known condition, available documents and the person authorized to confirm scope.

Map the interfaces

A work package may depend on equipment being stopped, an access route becoming available, scaffolding, lifting, another team or a review. Document those interfaces without assuming they belong in the contractor's scope.

Groupe Tremblay offers several industrial capabilities, including maintenance, custom scaffolding and lifting. Availability and inclusion need to be confirmed separately for the shutdown in question.

Assemble field information

Authorized drawings, photographs, surveys, intervention history and condition descriptions can support preparation. They may not replace an on-site validation.

Identify site-access requirements, permitted hours, controlled areas, onboarding processes and communication or photography restrictions. Do not transmit confidential content without authorization.

Build an understandable sequence

The sequence should connect prerequisites, activities, decision points and handoffs among teams. Durations should not be confirmed before scope and conditions are sufficiently understood.

Establish a method for discovered conditions: who records them, who decides, how the impact is assessed and how revised information is communicated.

Prepare closeout

Define the documents or confirmations expected at assignment completion. Closeout may address return of the work area, a record of work performed, remaining items and agreed documents. Exact content depends on the contract and facility practices.

Starting checklist

  • Shutdown objective and required outcome
  • Mandatory, conditional and optional work packages
  • Equipment, areas and known conditions
  • Drawings and documents with revision
  • Desired window and milestones
  • Access, interfaces and other participants
  • Decision responsibilities
  • Confidentiality requirements
  • Process for discovered conditions
  • Expected closeout deliverables
Next step

Is the scope of your next shutdown being prepared?

Share the planned work, desired window and known dependencies. The team can confirm which information is required to assess participation.
