1. 3D Laser Scanning

2. Laser Scanning Definitions: 1.) Laser Scanning: High speed reflector-less distance measurements coupled with angles used to produce a 3D “Point Cloud” 2.) Point Cloud – collection of 3D coordinate nodes that spatially depict a scene. 3.) Point Cloud Software – database driven, highly graphic intensive software that allows rich point cloud manipulation and computation 4.) Accuracy – 3D spatial uncertainty

3. o Laser Scanning Benefits: o Reduction - Direct labor costs of field data collection. o Increased Safety of collection efforts o Tool for launching into new markets and services o Can provide traditional deliverables from scan data o Ownership of the data: o Completeness of data sets for deliverables and checks o Recurring service fees from one data set o More accurate finished product – higher density data

4. o Reduced errors and rework: o Traditional methods: Greenfield projects see excess of 1% of the project budget to errors and rework, and Brownfield projects see excess of 5 – 10% of the project budget to errors and rework o Laser scanning methods: achieve better, faster, cheaper and lower-risk project execution by reducing errors and rework. Virtually eliminates Greenfield project errors and rework, and laser scanning reduces Brownfield project errors and rework by 2-5% o Contractor benefits: increased competitiveness and profitability o Business benefits: faster time to market, fewer days of lost production and reduction of concerns in public safety and environment

5. o Technology drivers o Advantages over traditional methods o Accuracy: laser scanner’s direct digital measurement and recording of existing conditions reduces project execution risks and field rework o Speed: with the ability to capture thousands of point per second, laser scanning greatly improves productivity o Completeness: Laser scanning provides a more complete capture of existing conditions and reduces the potential for errors in new design work o Laser scanner measure methods o Time-of-flight: calculate distance by measuring the time of flight of a laser pulse. Good for long ranges and accuracy o Phase-based: measure distance by calculating phase differences in the laser beam. Good for short ranges and scan rate

6. o Work process practices o When to use laser scanning: o Completing manual methods are to expensive by comparison o Completing methods introduce safety risks o When methods provide inadequate level of detail o When other methods would take too long o When errors represent a significant risk to project cost and schedule o Laser scanning project: o Determine the deliverable: work with customer to determine deliverable to guard against unnecessary work o Execute scanning project: use proper field techniques to capture desired data and determine registration method and set targets accordingly o Manage point-cloud data: process data to meet customer’s deliverable

7. o Deliverables o Process and power: o 3D models: of piping and building interiors to accurately map alignments of pipes and interior features for retrofit, new equipment install and capture of existing conditions o 2D drawings: traditional drawings for as-built conditions, documentation and biding o Snapshot Photos or Images o Civil, building and transportation: o 3D models: of existing conditions used for retrofit, road design, historic preservation and expansion design o 2D drawings: traditional drawings for as-built conditions, documentation, point creation and biding o Point clouds with 3 rd Party Software

8. Laser Scanning Best Practices Finish level one learning curve before attempting the first real project. Find inside technical champion that wants to drive it… Start using on existing projects immediately – even if only an hour a day. Most projects require that you mix scanning data with traditional survey data. (Total Station or RTK data) Deliver Snap Shots and Fly thru videos with your fee proposals as well as final deliverables. Bill by the job – not the hour if possible Branch well outside your traditional client list Don’t “Over Scan” the project Utilize other 3 rd party software including point cloud viewers Focus on developing “solution” workflows and deliverables; i.e. don’t just scan to say you scanned.
