Project Overview

Overview

At 17,275 square metres and spread across seven occupied levels, this UK commercial building was not a small Scan to BIM project. The structure housed basement plant areas, a full ground floor, five upper floors and a roof structure, each with its own structural logic, own floor profile and its own mix of columns, beams, joists, bracing and ceiling conditions. All needed to be captured from point cloud data and translated into a single coordinated LOD 300 Revit model.

The building was in active use. The point cloud had been captured by the client’s survey team and handed to Tesla CAD UK as the primary source of data. There were no simplified floor plates, no repetitive, typical floors to copy and no shortcuts. Every level had to be modelled from the scan.

The deliverable was the model plus a complete set of construction sheets, all extracted from the live Revit model and ready for use.

The Challenge

Large commercial buildings present Scan to BIM challenges that smaller projects do not. The structural elements across seven levels had to be modelled individually and correctly, family by family, with accurate naming and sizing throughout. Every shortcut, if taken, will eventually show up as an error in the model.

The major challenges were:

Floor slab profiling at scale: Commercial floor slabs are not flat. Years of loading, deflection and settlement mean the actual slab profile deviates from the design intent in ways that are invisible to the naked eye but visible in a point cloud. On this project, every floor was modelled by modifying sub-points on a 2m × 2m grid to match the actual surface profile captured in the scan. This is technically demanding and time-intensive, but non-negotiable for a model that is supposed to represent the building as it actually is.

Full structural scope: The scope covered structural walls, columns, slabs, beams, rainwater pipes, joists, bracing, roof structure, rafters, trusses, stairs, ramps, external and internal walls, ceilings, and bulkheads. Every element required correct family naming and sizing.

Sheet creation as a deliverable: The model was not the only deliverable. A complete sheet package had to be extracted from the finished model. The drawings had to be derived from the 3D model and construction-ready.

The Approach

Step 1

Point Cloud Setup & Level Establishment

The project began with the client’s point cloud data, imported into Revit. With a building of this scale, establishing accurate level datums and reference grids before modelling begins is critical.

Our team set project base point, survey point and level markers against the best-available reference data from the scan, then systematically identified coverage gaps or registration anomalies before production started.

Step 2

Structural Modelling, Floor by Floor

Modelling proceeded floor by floor from the basement to the roof. The floor slab profiling was carried out at each level using the 2m × 2m sub-point grid modification method, which is the most accurate technique available in Revit for replicating non-planar slab surfaces from point cloud data. This was applied consistently across all seven floors. All Revit families were named and sized correctly as work progressed.

Step 3

MEP Elements & Sheet Package

With the structural model complete, the limited MEP scope was added. Rainwater pipes and manhole covers were correctly located and sized from the scan data. The sheet package was then extracted directly from the finished model. Every sheet was checked for completeness, level referencing and drawing accuracy before being prepared for delivery.

The Outcome

The client received every deliverable required for the next stage of the project.

01

3D Revit Model

Complete LOD 300 structural model (basement to roof) with all families correctly named and sized. Rainwater pipes and manhole covers included.

02

Full Sheet Package

7 floor plans, roof plan, 7 reflected ceiling plans, 2 cross-sections, 4 elevations. All were extracted directly from the coordinated model.

03

Profiled Floor Slabs

Every floor slab modelled using 2m × 2m sub-point modification to capture the actual surface profile from the point cloud.

A model at this scale is only as useful as its accuracy. Tesla CAD UK’s approach on this project (profiling every floor to the point cloud, naming every family correctly and extracting the sheet package from the live model) is the difference between a Scan to BIM model that supports decisions and one that creates new ones.
