NavVis VLX3 Gen 3 for Building Survey and As-Built Documentation Malaysia

NavVis VLX3 Gen 3 for Building Survey and As-Built Documentation Malaysia

Accurate and comprehensive building documentation is essential for renovation, construction planning, engineering coordination and facility management. The NavVis VLX 3 Gen 3 wearable mobile 3D laser scanning system provides a professional reality capture solution for documenting existing buildings, complex interiors and large facilities in Malaysia.

By combining dual LiDAR sensors, panoramic imaging and Simultaneous Localization and Mapping (SLAM) technology, NavVis VLX 3 enables operators to capture three-dimensional spatial information while walking through a building. The resulting point cloud data can support as-built documentation, building measurement, renovation planning, Scan-to-BIM and digital building records.

For surveyors, architects, engineers, construction contractors and building owners in Kuala Lumpur, Selangor, Johor, Penang and across Malaysia, wearable mobile scanning offers a practical alternative or complement to traditional static surveying workflows.

Why Building Survey and As-Built Documentation Matter

Existing building drawings do not always represent actual site conditions. Buildings may undergo modifications, extensions, equipment installations and interior renovations without every change being reflected in the original documentation.

When design teams rely on outdated information, they may encounter unexpected structural dimensions, service clashes, installation difficulties or additional site visits.

A 3D laser scanning building survey captures measurable spatial information from the existing environment. This information can support the preparation of updated plans, sections, elevations, 3D models and other project deliverables.

Common reasons to conduct an as-built building survey include:

Renovation and refurbishment planning.

Existing building condition documentation.

Architectural and structural measurement.

Mechanical, electrical and plumbing coordination.

Building Information Modelling (BIM) development.

Factory and industrial facility modifications.

Property asset and facility management records.

Verification of existing layouts before new construction work.

What Is NavVis VLX 3?

NavVis VLX 3 is a wearable mobile mapping system designed to capture high-quality 3D point clouds and panoramic imagery. An operator carries the scanner through a site while its sensors collect spatial measurements.

Unlike conventional terrestrial laser scanners, which generally require multiple stationary setups, NavVis VLX 3 uses a mobile mapping approach to capture connected spaces during continuous movement.

This is particularly useful when documenting multi-room buildings, corridors, industrial facilities and large commercial properties where numerous static scanning positions may otherwise be required.

However, the choice between mobile scanning and terrestrial laser scanning must consider the project's accuracy requirements, site geometry, control network and final deliverables.

Key NavVis VLX 3 Features for Building Surveys

1. Dual 32-Layer LiDAR Sensors

NavVis VLX 3 uses two 32-layer LiDAR sensors to capture surrounding geometry. Each sensor has a specified maximum measurement rate of up to 1,280,000 points per second, and the system has an operational range of up to 50 metres under suitable conditions.

These sensors help document walls, floors, ceilings, structural features and accessible building service areas.

2. Four 20 MP Panoramic Cameras

The system incorporates four 20-megapixel cameras to capture panoramic imagery alongside spatial measurements.

Panoramic images provide valuable visual context when identifying rooms, building finishes, doors, corridors, installed equipment and other site features.

3. SLAM-Based Mobile Mapping

SLAM technology allows the system to estimate its movement and construct a map of the surrounding environment during scanning.

For building surveys, this can reduce repeated scanner setup activities and help operators capture interconnected areas efficiently. Reliable results still require appropriate scan route planning, environmental features and quality checks.

4. Survey Control Point Integration

NavVis VLX 3 supports ground and wall control points. When accurate project coordinates are required, appropriately surveyed control points can support registration and alignment of the mobile scanning dataset.

For professional survey work, control points should be planned according to site geometry, project tolerances and the required coordinate reference system.

5. Live Scanning Feedback

The built-in 5.5-inch touchscreen provides live feedback to assist operators during data collection.

This helps the scanning team review coverage and tracking conditions before completing the site visit.

How NavVis VLX 3 Supports As-Built Documentation

Existing Building Geometry Capture

The first step in as-built documentation is capturing the physical geometry of the existing building. NavVis VLX 3 can record accessible interior spaces, structural surfaces and architectural features as a 3D point cloud.

Survey teams can use the processed dataset as a reference for identifying dimensions and preparing building documentation.

Floor Plans and Building Sections

Processed point clouds can be imported into compatible CAD or BIM software. Designers can then extract or model floor plans, elevations, cross-sections and architectural layouts according to the project's required detail.

The scanner captures spatial data; production of final CAD drawings normally requires additional processing, drafting and quality assurance.

Renovation and Refurbishment Projects

Before renovating an office, hotel, hospital, shopping centre or industrial building, contractors need to understand the existing conditions.

Mobile 3D scanning can help document the building before demolition, redesign or installation work begins, reducing reliance on incomplete historical drawings.

Mechanical, Electrical and Plumbing Documentation

Building services can include pipework, ventilation ducts, cable trays, electrical equipment and mechanical installations.

As-built 3D scanning for MEP coordination can provide spatial reference data for planning new services and reviewing available installation space. Small or concealed components may require additional targeted measurement.

Scan-to-BIM for Existing Buildings

NavVis VLX 3 point cloud data can support Scan-to-BIM workflows, where captured geometry is used as a reference for developing a Building Information Model.

Creating a BIM model typically involves interpretation, modelling, object classification and checking against specified levels of detail. A point cloud is not automatically equivalent to a complete BIM model.

Typical Building Survey Workflow Using NavVis VLX 3

Step 1 - Define Survey Requirements

Confirm the building area, survey objectives, required accuracy, coordinate system and final deliverables. Determine whether the project requires point clouds, CAD drawings, BIM models or visual documentation.

Step 2 - Conduct Site Reconnaissance

Review access restrictions, floor layouts, staircases, corridors, reflective surfaces, moving objects and any safety requirements. Identify areas that may need supplementary measurements.

Step 3 - Establish Survey Control

Where required, establish suitable control points using appropriate survey instruments and methods. Control distribution should support registration and independent accuracy verification.

Step 4 - Capture the Building

Operate the NavVis VLX 3 along a planned walking route. Maintain sufficient geometric overlap and follow the manufacturer's scanning recommendations to support reliable SLAM tracking.

Step 5 - Process Point Cloud Data

Transfer and process the captured data using the appropriate NavVis software workflow. Review processing results, trajectory quality, registration and coverage.

Step 6 - Verify Accuracy and Completeness

Compare selected measurements or independent check points against the project's acceptance criteria. Identify any areas requiring rescanning or supplementary survey work.

Step 7 - Prepare As-Built Deliverables

Export compatible datasets and prepare the required drawings, models or documentation in suitable third-party software. Record assumptions, limitations and survey quality checks.

NavVis VLX 3 vs Traditional Building Survey Methods

Consideration | NavVis VLX 3 Mobile Scanning | Traditional Methods |

Data Collection | Continuous wearable mobile capture | Stationary scanning or individual point measurement |

Large Interior Coverage | Can be efficient for connected accessible spaces | May require numerous scanner setups |

Point Cloud Output | Yes | Available with terrestrial laser scanners |

Survey Control | Supports surveyed control points | Can establish or use survey control |

Accuracy | Depends on SLAM, control, environment and processing | Depends on instrument, setup and survey method |

Best Application | Broad spatial documentation and mobile reality capture | Targeted measurements and applications requiring specific static survey methods |

Important: Mobile scanning does not eliminate the need for total stations, GNSS, terrestrial laser scanners or independent verification when project requirements demand them. Combining methods may provide a more effective survey workflow.

Common Building Survey Challenges

Incomplete Scan Coverage

Closed rooms, obstructed spaces and restricted areas may result in missing data. Review scanning coverage during fieldwork and plan additional capture where necessary.

SLAM Tracking Difficulties

Long repetitive corridors, large featureless spaces and certain dynamic environments can create challenges for mobile mapping. Suitable route planning, loop closures and control points can improve workflow reliability.

Reflective and Transparent Surfaces

Glass, mirrors and highly reflective materials can affect LiDAR returns. These surfaces may require additional interpretation or complementary measurement methods.

Incorrect Accuracy Assumptions

Do not assume that every dimension or coordinate automatically satisfies a 5 mm project tolerance. Verify the delivered dataset against independently established survey requirements.

Point Cloud to CAD or BIM Conversion

Capturing a point cloud is only part of the documentation process. Producing accurate drawings and models requires suitable software, technical skills and defined deliverable standards.
