Review a lifting plan when site conditions change

A lift plan is based on assumptions about the load, equipment, ground, route, people and surrounding work. If any material assumption changes, the lift team must decide whether the existing plan remains valid. Continuing under a signed document that no longer describes the site can be more dangerous than having no document at all, because it gives false confidence to everyone involved.

The Health and Safety Executive (HSE) LOLER overview says lifting operations must be properly planned by a competent person, appropriately supervised and carried out safely. The LOLER Approved Code of Practice and guidance says an initial plan for routine work may be reused only while still valid and may need review if circumstances change. This page covers the reassessment trigger and controlled new decision, not a generic lift-plan template or a single issue such as changed crane ground.

Identify the changed assumption

Compare today's conditions with the plan: load weight and centre of gravity, lifting points, crane or hoist configuration, rigging, ground or support, travel path, exclusion area, weather, visibility, nearby services and other trades. A substitute lifting accessory or altered pick point can matter even if the nominal load is unchanged. Record exactly what changed, when it was discovered and who identified it.

Distinguish a variation already included in the plan from a new scenario. Some routine operations have planned ranges or alternative positions. The competent planner must decide whether today's condition falls within those parameters. The crane operator or slinger should not have to improvise a technical calculation at the workfront because a document owner is unavailable.

Stop the affected lift and secure the area

If the plan cannot be confirmed, pause the lift or do not start it. Stabilise any suspended or partially handled load under the lifting team's safe procedure and keep people out of the danger zone. Tell the lift supervisor and affected contractors. A brief interruption to replan can prevent a much larger loss; an informal “we have done similar before” is not evidence that this lift remains controlled.

Record the temporary restriction and who may authorise a restart under the employer's arrangements. If site changes affect adjacent work, coordinate the exclusion zone and sequence with those teams. The HSE planning guidance places construction-phase coordination with the principal contractor where applicable.

Reassess with a competent planner

Give the planner updated site facts, drawings, equipment information and any technical reports. Ground-bearing information may need specialist input. A changed load may require confirmed weight or lifting-point details. A different crane configuration may alter radius and capacity. The planner should update the risk assessment and method at the level appropriate to the operation's complexity. HSE's LOLER guidance says planning complexity and resources should reflect the operation's difficulty.

Do not assume a new plan resolves equipment condition. Check the relevant inspection and thorough-examination evidence separately. A safe lift method requires both a suitable, maintained item of equipment and a workable operation. If a defect or missing certificate is discovered, keep that as a distinct restriction with its own competent review.

Approve and issue the operative version

Give the revised plan a version, date, reason for change, competent planner and defined scope. Preserve the superseded plan but remove it from the crew's active pack. Record any separate technical approvals, permits or temporary-works dependencies. The person supervising the lift should have the current document and be able to explain its key controls. A revised page in a central folder does not help if the team at the crane is using an older printout.

Where the change is limited, an approved amendment may be sufficient under the organisation's method. Where the lift is fundamentally different, a new plan may be needed. The form is less important than whether a competent person reassessed the actual operation and the crew understands the result.

Rebrief the complete lifting team

Tell the crane operator, slinger/signaller, lift supervisor and affected contractors what changed. Confirm signals, communications, exclusion boundaries and stop-work conditions. If crews change shifts, brief the replacements. Ask for a practical read-back of the critical difference, rather than treating signatures as proof of comprehension. Monitor the first execution against the revised plan and pause again if site conditions differ further.

Example: altered load route

A planned plant lift crosses a clear compound. Before the lift, another contractor installs a temporary service trench along the agreed crane route and moves a materials stack into the landing area. The lift supervisor stops the operation and notifies the principal contractor. The competent planner checks the new ground and route information, revises the position and exclusion zone, and confirms the equipment configuration. The site moves the conflicting materials, updates the plan and briefs every person in the lifting team. Only then does the lift proceed.

The issue was broader than the trench alone: the landing area and coordination with another contractor also changed. A site note saying “ground checked” would not have addressed the whole lift.

Keep a decision trail for repeated operations

Retain the original plan, change trigger, updated facts, competent review, approved version, briefing and actual outcome. For recurring lifts, identify parameters that require a fresh review each time. If similar last-minute changes occur regularly, improve scheduling and interface planning rather than accumulating one-off exceptions. A later reviewer should be able to see why the team believed the operation was safe on that day.
