Industrial Laser Scanning for Shutdowns and Retrofits
Industrial laser scanning records visible plant geometry before a shutdown or retrofit. Plan the work around replacement routes, tie-ins, crane access, temporary works and fabrication interfaces. Define the coordinate controls and required coverage. Check and organize the cloud so the team can find the information it needs before the outage starts.
Our Approach
How we help your team
Your shutdown window leaves little room for unexpected site conditions. We help your engineering and construction teams investigate visible tie-ins, equipment interfaces and access constraints while there is still time to plan the work.
We plan scans around the work package and site operating rules. We include tie-ins, travel routes, lifting clearances, access and coordinate controls. We register, review and organize the data so engineering and fabrication teams can assess critical conditions before the outage.
Part 1 of 6
Move uncertainty out of the outage window
A shutdown puts demolition, installation, inspection and startup into a short window. A late discovery can delay the whole sequence. Existing drawings may show the original design rather than years of changes. Hand measurements can check selected dimensions. Dense pipes, cable trays, platforms and equipment make it harder to see how all the connections fit together.
A scan before the outage gives engineering, construction and fabrication teams a shared view of the site. They can review geometry, routes and the planned sequence while options remain open. Field checks and operational planning are still needed. The aim is to find and investigate differences before crews and equipment are committed to the shutdown.

Define the work package before defining the scan
Start with the work package. For equipment replacement, capture the equipment envelope, foundations, nozzles and nearby pipe supports. Electrical feeds, doors, laydown areas and the removal route may matter too. A pipe retrofit may need a closer look at tie-ins, support locations and flange orientation. Include nearby clashes and the route for installing the new spool.
An area description such as 'scan the mechanical building' does not define the whole task. Mark the systems to remove, retain or connect. Identify the smallest features that matter, operating limits and project coordinates. These details help the provider plan scan spacing, resolution, targets and field time around the work your team needs to do.
- List tie-ins, nozzle faces, baseplates and other interfaces that control the replacement design.
- Map exclusion zones, hot surfaces, hazardous areas, escorts and permitted work periods.
- Include removal, lifting and installation paths when constructability is part of the decision.
- Separate authoritative survey or process information from geometry observed in the cloud.

Plan safely for an operating facility
Scanning must follow the facility's safety program. The owner and provider should agree site orientation and personal protective equipment. Review energized systems, classified areas, hot-work restrictions and line-of-fire risks. Include moving equipment and work at height. Confirm any approvals needed for the scanner and its accessories. Measuring from a distance does not remove these site requirements.
Plan the fieldwork to limit disruption and keep scan positions safe and stable. Steam, dust, vibration and changing operations can affect the data. Temporary obstructions and reflective surfaces can leave gaps or noise. Review priority areas on site. If a view is unusable, replace it while access is still available.
Part 4 of 6
Protect the coordinate and registration network
Large plants can create long scan chains through similar pipe racks and narrow corridors. Repeated geometry may give the software weak clues in some directions. Add cross-connections and loops to check alignment. Targets and survey control can help detect drift. When required, they also connect the cloud to the plant's established coordinates.
Plan control with the responsible survey or plant team. Keep checkpoints separate from points used to align the scans when they are meant to verify the result. Review both the overall network and the local geometry at critical connections. A good plant-wide average does not replace a check at the tie-in that controls the work.
Part 5 of 6
Turn the point cloud into an execution resource
Agree the output for each work package. Engineering may need an indexed cloud to inspect. Fabrication may need pipe centerlines, flange planes, extracted geometry or a defined model. Construction planners may need access sections, comparison views or a visual record. Discuss asset records separately. Geometry alone does not establish an equipment tag, material, condition or maintenance history.
Model the detail that the decision needs and note any simplification. Existing pipe may not be straight, round or square to the plant grid. Insulation can hide its outside diameter. A cloud does not reveal wall thickness or internal condition. Delivery notes should separate measured surfaces, interpreted centerlines, owner records and assumptions that have not been checked.

Review readiness before shutdown approval
The handoff should explain what was captured and how it was checked. Include the source basis, registration report, coordinates and coverage limits. State the file formats and software versions, with sample quality-review evidence. Review the critical work packages rather than only touring the full cloud. Assign open questions before using the dataset as approved project input.
We manage planning, capture, registration, review and the agreed point cloud, CAD, BIM or documentation output. Tell us which equipment or line is involved and what decision the data must support. Share the access window and the output you need. Those details let us define the work more clearly than floor area alone.
Check the visible tie-ins and access routes before the shutdown starts. Deliver the data with its limits and review evidence so the team can plan the work.
