BIM Scanning Project

Lifecycle Processes

▪ The application of laser

scanning technology has

been popular in the

topographic and survey fields

for many years. However,

recent advances in hardware

technology and Building

Information Modeling (BIM)

processes are promoting the

use of scanning technologies

in the building construction

industry. Researcher with FARO Focus3D X330 –

LASER SCANNER, Toronto, Canada32

Laser Scanning Technology in

Construction

▪Scanning for building construction is being

applied most often to existing structures or

facilities to model accurate as-built conditions,

but we are also seeing an emergence of

applications relating to new construction work.

33

Laser Scanning Technology in

Construction

Scanner utilized for project:

FARO Focus3D X330

▪Range: 330m

▪Accuracy: 2mm

▪Resolution: 1.5mm @ 10m

▪Speed: ~1 million points

per second

FARO Focus3D X330 – LASER SCANNER34

SUCES Scanning Equipment

The chosen structures that were scanned and

modelled at the SUCES campus were as follows:

▪English Style House (Landscaping Training

Facility)

▪Japanese Style House (Landscaping Training

Facility)

▪Agricultural Training Facility (Greenhouse)

35

SUCES Scanning Process

Researchers planning scans at Landscaping Training Facility (SUCES) – In-Field Photos

Before the scanning takes place, a scan

plan consisting of station locations and

desired structures/ objects to be

recorded is produced.

Researcher with FARO X330

Facility (SUCES) – In-Field

When objects and

environments are

too large to be

captured by a

single scan,

multiple scans are

performed in the

surrounding vicinity

of the structure and

are stitched

together using

software

37


English (Above) and Japanese

(Right) Style Houses with FARO

X330 – Landscaping Training

Facility (SUCES) – In-Field Photos

These two structures were scanned to obtain

building geometry at all angles

The houses were connected through an adjoining

walking path that encircled a man-made pond in

the middle

The pathways were also scanned and modelled

as topography, as the English house stood at a

higher elevation than the Japanese house

Agricultural Training Facility Exterior (SUCES) & FARO X330 – In-Field Photo

The multiple scans

taken by the

FARO Scanner

are tied together

or registered using

the software,

SCENE.

The white spheres

or “targets” placed

around the

structure aid in the

registration

process within the

software during

post-processing

40

SUCES Registration Process

(FARO SCENE)

White Spheres

how the white

spheres are

displayed in the

scan registration

software, SCENE

Also in the view is

the scanner head

showing where

the scan station

was situated

Another example

of sphere target

placement shown

in next slide41


▪ As scans are recorded in the field, each scan position is assumed to be 0,0,0

and one direction (north), without correction, the scans will stack on top of

each other in the SCENE software environment (left image)

▪ Post processing of the scan data involves transforming the X,Y,Z coordinates

and north orientation to fit scans together much like pieces of a 3D puzzle

(right image)

Example of Unregistered Scans – (SCENE) Example of Registered Scans – (SCENE)

42


▪The process of stitching

together multiple scans in

software is called scan

“registration”

▪There are several methods

to register scan data, we

will focus on target based

scan registration using the

sites at SUCES as an

example to explain

registration principlesExample of 3D Checkerboard Survey

▪ Example showing how physical placement of white

spheres at different positions and elevations is

necessary to obtain accurate spatial data (x,y,z)

44


Diagram showing the

conceptual scheme for

target based registration

using spheres

- 3 fixed spheres at the

start of the loop around

structure

- 6 spheres that move

with each movement of

the scanning station (3

in the back, 3 in the

front, at least)

Example of scheme shown

in next slide

45


Agricultural Training Facility Interior (SUCES)

& FARO X330 – In-Field Photo

Interior scans of structures are

registered using the same principle

(target based), using doorways or

windows to register the exterior

scans to the interior.

Scan Registration (FARO SCENE)

Screenshot in SCENE showing two different scans (red and green)

registered together using automatic cloud-to-cloud method (not covered in

this presentation) with an average discrepancy of less than 5 mm49


White Spheres

▪ Once all scans are stitched together or

“registered” the larger scan file can be

exported from SCENE into an

Autodesk ReCap file as a point cloud

▪ When the 3D point cloud is generated,

the data can be further exported to

many common CAD, modeling and

BIM programs to generate 2D CAD

drawings or 3D models

50

SUCES Point Cloud Data

▪ 3D laser scanning technology digitally captures the

dimensions and spatial relationship of objects using a line of

laser light. The scanner outputs point clouds, which

accurately replicate the scanned objects or structures. Point

cloud files can be viewed in Autodesk ReCap.

▪ In order to start modelling the point cloud needs to be

imported from ReCap into Revit.

▪ Modeling levels are then created based off the common

points across the point cloud.

structure is no longer editable. All of the systems

can then be added to the file

▪Plumbing systems were the

primary focus for the

model
