1. Understand the history of laser-scanning and its development within the built environment.

2. Utilizing Scan to Building Information Modeling (BIM) tools.

3. Implementing Sustainable Practices through Scan to BIM.

Learning Objectives

History of Laser Scanning

• LIDAR (Light Detection And Ranging)

• Laser scanner emits laser pulses in a predefined array pattern. Pulse reflects back to scanner upon registering a solid object. Coordinate values are calculated for the point struck by the laser. In addition, coordinate points are assigned an "intensity value." By recognizing changes in intensity value between points, different building materials can be identified.

• Individual scans are then registered together to form overall “point cloud” of the building.

• This point cloud — made up of more than 60 million points, yields a level of detail down to one quarter-inch.

• Unfortunately the file size of the “point cloud” is often several gigabytes in size.

Laser Scanning

Scan – Up to 500,000 pts./sec

Range – 900 feet

Accuracy - 1/4”

Laser - Eye safe Class 3R - DIN EN 60825-1

How to Implement Scan to BIM.

• Building Information Modeling (BIM)

• Database of information rather than electronic

drawing.

• Model queries-

– How many?

– What type?

– Interface and collaboration

– Network Solutions

Building Information Modeling

• Parametric Information

• 4d – cost

• 5d – schedule

• 6d – sustainability

• Geographic Information System (GIS)

• Transformative software beyond CAD

Scan to BIM

enables an interactive engagement

with the existing environment.

• Ability to create smart structures out of existing

conditions (or as-builts)

• Integrate campuses into an integrated network.

• Remote review and management of holistic

systems not just individual structures

Examples

• Different types of Scanning

• Photo graphic

• LIDAR

• Portable LIDAR

Selling Scan to BIM as an Added Value

• Selling Scan to BIM as an added value service to

clients through stand-alone development or an

integral component of project life-cycles.

Implement 3D imaging into your practice

• Team up with a local 3D imaging service provider.

• Extend your service into creating existing

conditions

• BIM execution and management plan

Laser Scanning Benefits

SURVEYING/PRE-DESIGN

1.Immediate orthographic projections for survey.

2.Accurate accounting of scope for design purposes.

3.Dimensionally accurate data

4.Reduced surveying time.

CONSTRUCTION DOCUMENTS (DESIGN)

1.Precise location of all Architectural features

2.Orthographic projections increase dimensional and

architectural accuracy while reducing production time and

saving money.

3.Remote access reduces site visits and improves design

efficiency.

4.3D visualization facilitates troubleshooting, leading to

improved design.

Laser Scanning Benefits

BIDDING

1. Remote access results in more accurate contractor pricing.

2. Remote access reduces bid qualifications.(Less Exclusions)

3. Reduces site visit coordination.

CONSTRUCTION/CONTRACT ADMINISTRATION

1.Remote access improves communication between all parties

2. Fewer change orders

3. Eliminate unnecessary site visits

POST-CONSTRUCTION

1. Remote access for property management to obtain services

from vendors

2. 3D archive of scope at time of data capture.

3. Foundation for future development of 3D database of building

information

4. Marketing

Selling Scan to BIM as a Service

• Treat BIM more than CAD

• 3D imaging is part of Lifecycle BIM.

• Useful at the design and construction level,

necessary for operations.

Photogrammatry

• Non-Laser Scan 3d Imaging

• Digital photo

• Map photo over 3d model

The Future

• 3d printing

Summary

• Build BIM files from Point Clouds (3d

imaging)

• Use new BIM models for

– energy modeling

– facility management services

• and Point clouds (3d imaging) can be

brought into a BIM
