Laser Scanning 101: Introduction

LiDAR…used to create point clouds

3d measurement for a 3d world

What is Laser Scanning?

Point Clouds--Advantages

Comprehensive

Non-Contact

Distance

Accurate

Fast!

Updateable

Software integration

Proven

Photogrammetry

Total station

Penetrating

Metrology

Limitations Include:

• Line of sight

• Distance

• Scanning/Processing techniques

• Material being scanned

• Angle of incidence

• Type of scanner

• Instrument calibration

Laser Scanning…It’s Not…

What’s the Goal/Objective?

Laser Scanning Platforms

Nothing is built per the plan--100% failure rate

Human error in construction

Poor design

Scheduling pressure

Problematic/inexperienced owner

Competing objectives—trade labor

Financing issues

Change orders

Rework issues

Laser Scanning—Driving Market Factors

Adoption & Current Users

Adoption remains incredibly low

Current market includes:• A/E/C Industry…driven by architects & GC’s• Oil/gas• MEP• $100m+ renovation projects• Automotive• Surveyors• Government—civil• Youth..!

Almost exclusively used in renovation/retrofit projects…

Extremely low implementation in new build/construction markets

Diffusion of Technology CurveDr. Everett Rogers

LABOR

• Planning• Engineering/design• Building--construction

Laser Scanning Ultimate Driving Force…SAVINGS!

MATERIAL

• Aggregate/concrete• Steel• MEP• Drywall• Building envelope• Finish carpentry

Return On Investment

Case Study Examples

Scan Data = 2d Deliverables

Scan Data = Site Work Deliverables

Scan Data = Civil/Topo Example

Scan Data = Topo

Scan Data = Floor Flatness

Scan Data = Topography Report

Scan Data = Building Envelope & Prefabrication

Scan Data = Pre-installation Design Conflict

Deviations

Scan Data = Fabrication to Existing Conditions

Scan Data = Quality Control

Validation of the deck edge

Scan Data = Accurate As-Built Conditions

Scan Data = Leasable SF

Scan Data = 3d Models

Laser Scanning and Pre-Fabrication

Other Important Stuff

How Much Does it Cost?

Capture the Subject = 10-20%

Creating the Deliverable = 80-90%

When to Bring Scanning In-House (Self Perform)

Recurring needs/demand

• Changing/evolving environment

Ability to process—create usable deliverables

Costs associated are fully understood

• Scanner

• Software

• Calibration

• Training

Less expensive than a service provider

Laser Scanning—Service Provider Selection

Picking a service provider…

• Experience in the specific market/project type

• Outsourcing the deliverables [good/bad]

• Insurance

• Scheduling

• Consultation/coaching--implementation

• Full disclosure (who’s doing the work)

• Price is NOT as important at VALUE

“Best” Hardware/Software

Buyer beware…

• Trust but verify

• Know your goal(s)

• Actual costs

• Evolution

• Small guys

• Golf clubs and golfers…

The Future…

Trade labor shortage will drive

VR/AR !

Indoor mobile scanners

Lower cost software

Easier to create deliverables

Owners demand more

Prefabrication

Lien building practices will lead

New construction QA/QC
