3D Laser Scanning for Hunter Valley CHPP Upgrades
3D Laser Scanning for Hunter Valley CHPP Upgrades
Modifying an existing coal handling and preparation plant requires more than a set of historical drawings.
Conveyors may have been repositioned. Chutes may have been repaired or replaced. Platforms, pipework, electrical services and structural supports may have been added over many years of plant operation.
When the available drawings no longer represent the installed condition, mechanical design can begin with uncertainty.
Hamilton By Design uses engineering-grade 3D laser scanning to capture the existing condition of Hunter Valley coal handling and preparation plants before mechanical, structural and materials-handling modifications are developed.
The Challenge with Brownfield CHPP Engineering
Coal handling and preparation plants are often densely arranged industrial environments.
A relatively small project area may contain:
conveyors and transfer points
chutes, hoppers and bins
structural steelwork
equipment support frames
platforms, stairs and handrails
pipework and electrical services
maintenance-access areas
existing equipment and guarding
New equipment must fit within this existing arrangement.
Even a small dimensional error can affect fabrication, installation access, chute alignment, conveyor interfaces or structural connections.
Traditional site measurement can provide selected dimensions, but it may not fully capture the relationship between surrounding equipment, steelwork and services.
Capturing the Existing Plant
Terrestrial 3D laser scanning records the visible plant geometry from multiple scanner positions.
The resulting scans are registered into a coordinated point cloud that can be reviewed by engineers, designers, fabricators and project teams.
Depending on the project scope, the point cloud may capture:
conveyor head and tail arrangements
transfer chutes and discharge points
hopper and bin geometry
structural columns and support frames
equipment centre lines
platform and walkway arrangements
floor and structural elevations
maintenance clearances
pipework and service routes
proposed removal and installation paths
This creates a detailed spatial record of the actual installed plant.
From Point Cloud to Engineering Information
The purpose of 3D laser scanning is not simply to produce a visual model.
The point cloud becomes a practical engineering reference that can support:
existing-condition verification
conveyor modification design
chute replacement and redesign
transfer-station upgrades
equipment replacement
structural support modifications
platform and access design
pipework rerouting
mechanical fit-up verification
clash detection
fabrication planning
shutdown installation sequencing
Critical dimensions can be extracted from the point cloud while the broader plant arrangement remains available for engineering review.
This helps the design team understand not only where an item is located, but how it relates to the surrounding plant.
Reducing Brownfield Project Risk
Brownfield modifications frequently encounter problems when design work is based on incomplete or outdated records.
Typical risks include:
fabricated components not fitting the installed plant
unexpected clashes with structural steelwork
insufficient maintenance clearances
incorrect equipment interface locations
restricted crane or installation access
unplanned site modifications
additional shutdown work
return visits for missing measurements
Capturing the existing condition before detailed design can identify many of these constraints earlier.
The design can then be developed around the real plant arrangement rather than assumed dimensions.
Supporting CHPP Shutdown Planning
Shutdown periods within operating coal plants are often limited.
A component that cannot be installed as planned may affect several trades, crane movements and dependent activities.
A coordinated point cloud can assist the project team in reviewing:
equipment removal routes
installation envelopes
temporary access requirements
lifting and handling constraints
structural interfaces
work sequencing
surrounding obstructions
maintenance access after installation
This does not replace detailed shutdown planning, but it provides a stronger geometric basis for that planning.
Engineering Deliverables
Depending on the requirements of the project, Hamilton By Design can provide:
registered point-cloud datasets
E57 point-cloud files
Autodesk-compatible point clouds
extracted engineering dimensions
existing-condition CAD geometry
SolidWorks models
Autodesk Inventor models
STEP and SAT files
general arrangement drawings
sections and elevations
fabrication drawings
installation drawings
demolition drawings
clash-review information
The deliverables can be tailored to suit the engineering stage, from early investigation and feasibility through to detailed design and fabrication support.
Engineering-Led 3D Laser Scanning
The value of the scanning process depends on understanding what the engineering team needs to confirm.
Before site capture, the scanning envelope should be defined around the relevant mechanical, structural and installation interfaces.
This may include identifying:
critical equipment connections
design tie-in points
structural support locations
areas requiring greater scan density
elevated or restricted areas
potential hidden surfaces
future equipment positions
required installation clearances
This engineering-led approach helps ensure the point cloud contains useful design information rather than unnecessary data alone.
Hunter Valley CHPP Engineering Support
Hamilton By Design provides 3D laser scanning, mechanical engineering, CAD modelling and drafting support for brownfield industrial projects throughout the Hunter Valley and regional New South Wales.
Applications include:
coal handling plants
preparation plants
conveyors
transfer stations
chutes and hoppers
processing facilities
workshops
maintenance facilities
structural access systems
equipment replacement projects
Our objective is to provide reliable existing-condition information that helps project teams reduce uncertainty before design, fabrication and installation.
