BIM Modeling of Metropolitan House Serviced Offices

Project Details

GIS-Point was engaged to update the digital documentation of an existing multi-storey commercial building following significant changes since the previous survey conducted in 2012.

The project involved processing newly acquired point cloud data and developing an accurate LOD300 BIM model covering the basement, ground floor, and seven upper levels.

The scope included modeling structural elements, architectural components, and visible building services, as well as generating coordinated 2D CAD drawings including floor plans, elevations, and sections at 1:50 scale.

The resulting BIM model provides an up-to-date digital representation of the building to support the client’s planning and design process.

Client: A UK-based architectural practice specializing in architectural design, planning, and project delivery for commercial and mixed-use developments.

Sector: Construction

Sub Sector: Private Construction

Services: Scan to BIM

Solution:
3D BIM modeling of the existing building based on point cloud survey data
Development of an LOD300 Revit model including structural elements, external envelope, and building services.
Generation of accurate 2D CAD drawings (plans, elevations, and sections at 1:50 scale) from the BIM model.

Location: Potters Bar, United Kingdom

People:
GIS-Point assembled a dedicated team of BIM specialists and a BIM coordinator to deliver the project efficiently.
The team collaborated closely to process point cloud data and develop an accurate LOD3 BIM model of the building, ensuring compliance with the client’s technical requirements and modeling standards.
Continuous coordination and internal quality control enabled the team to maintain consistency across all floors and deliver the required BIM model and CAD documentation within the agreed scope.

Technology and Software:
The project utilized Autodesk Revit for BIM model development, Autodesk ReCap for processing the point cloud data, and AutoCAD for generating 2D CAD drawings. Internal cloud storage supported the management and segmentation of the large point cloud dataset

Process & Challenges

Process:

The project began with the preparation and processing of the provided point cloud data to establish a reliable basis for BIM development.
GIS-Point utilized BIM workflows to interpret the scan data and reconstruct the existing building geometry within the BIM environment, ensuring consistency across all floors and compliance with the client’s technical requirements and LOD standards.

Our process included:

Importing and processing point cloud data within Autodesk Revit.
Developing the LOD300 BIM model including structural and architectural elements.
Modeling visible building services, plant equipment, and external building features based on the scan data.
Generating coordinated 2D CAD drawings, including floor plans, elevations, and sections at 1:50 scale.
Performing internal quality control and coordinating with the client to ensure accuracy and compliance with project requirements.

This workflow ensured the creation of an accurate digital representation of the building to support the client’s planning and design activities.

Challenges:

The project presented several technical challenges related to the very large point cloud and documentation requirements. GIS-Point addressed these issues through optimized BIM workflows and coordinated teamwork.

Key challenges included:

Very large point cloud:
The provided point cloud was extremely large and difficult to process within a single BIM environment. GIS-Point segmented the point cloud and distributed it among BIM specialists. Using powerful computers with high specifications and internal cloud storage, the team efficiently processed the data while maintaining model accuracy.
Multi-floor coordination:
The building included multiple levels requiring consistent alignment of structural and architectural elements. Standardized BIM workflows ensured accuracy across the entire model.
Missing Revit annotation library:
The client was unable to provide a Revit annotation library required for drawing documentation. GIS-Point developed a custom annotation library to ensure clear and consistent drawings.

Overcoming these challenges enabled the delivery of an accurate BIM model and coordinated CAD documentation.

Result

An accurate LOD300 BIM model of the building was developed from point cloud data in Autodesk Revit. The model includes structural and architectural elements, visible services, and external features across all floors.

In total, the model contains 13,500+ modeled elements and represents a building with an approximate processed area of 26,000 m². A coordinated set of 1:50 CAD drawings — including floor plans, elevations, and sections — was generated directly from the BIM model.

BIM Modeling of Kindergarten “Bitīte”

GIS-Point was engaged to develop a BIM model of a two-storey kindergarten building based on available architectural documentation and point cloud data. The project focused on creating an accurate digital representation of the building geometry, including key architectural elements such as walls, floors, roofs, and openings. The resulting BIM model was structured and optimized to support coordination workflows and prepared for export in IFC format to ensure compatibility with industry-standard BIM platforms.

BIM Modeling of Frenchton Farmhouse

GIS-Point was commissioned to develop a digital BIM model of an existing historic farmhouse based on laser scanning data. The project included point cloud processing and modeling of the building envelope and basic interior layout in Autodesk Revit at LOD 300.
Scan-to-CAD Documentation of Pied Chateau

GIS-Point was engaged to process the laser scan data and produce accurate architectural drawings of the building. Using the provided point cloud dataset, the team analyzed the existing structure and developed detailed floor plans, building sections, and façade drawings reflecting the current condition of the property. The project focused on transforming complex survey data into clear and structured documentation to support further architectural and engineering work.
