Creating a 3D Scan to BIM Model of a 16th-Century Heritage Monument

HitechDigital helps a surveying and BIM services company from the UK to create a Point Cloud to BIM model at LOD 400 for a 16th-century heritage building.

Background

In 2014, a surveying and BIM services firm from Manchester, UK, took on a new project for renovation, maintenance, and facilities management of a 16th-century heritage building.

The project required 3D Point Cloud to BIM modeling of the building to create a digital replica preserving its signature architecture. This building information model in 3D was to carry information on all as-built conditions. The monument was laser scanned, generating 3D survey measurements and high-resolution survey images.

Challenges: Creating the 3D model of such a large area within a couple of months

This is one of the largest and most grandiose 16th-century monuments in the UK, spread across an area of 580,000 sq. ft. (13.3150 acres) with intricate architectural features. Its huge size and irregular geometric complexity made it challenging to scan the entire area including rooftops and roof components.?

The monument was laser scanned with every detail including survey measurements and survey photos. Preserving architectural prominence was a challenge for Point Cloud to BIM professionals, along with maintaining high-quality detailing at LOD 400. The 200GB of point cloud data that was generated posed another challenge in processing it into a single BIM model.??????

Solution: HitechDigital handles the Scan to BIM conversion

The laser scanning services provider contacted HitechDigital for Scan to BIM conversion based on scan data. A 3D BIM model in Revit at LOD 400 was created by validating geometric details and creating Revit families for components. Detailed documentation of the building elements was extracted from .....
