HDS Laser Scanners

• Gather 3-dimensional information in point clouds
  without hands on contact.
• Get information from unsafe working environments
  without entering the environment
• Get information on unreachable objects
• Gather mass information for an area.
• As-built verification on piping, structural
  steel, and equipment.
• Reduce re-work to 1 or less.
• Fast and Accurate
• Accurate to within /- 1/8 inch

6
How Scanners Work

• Scanners emit a laser beam that reflects off
  objects.
• The time it takes for a return of the laser and
  angle of the mirrors are converted and
  transferred to a laptop and stored as individual
  points in a 3-dimensional viewer.

A Typical Falk PLI Scan Job

• Determine what the client needs/wants done.
• Use scan targets for tie-in to local coordinate
  system and verify position of scanner is good
  from start to finish.

Sample Scan Work

• Blast Furnace
• Falk PLI can gather 3-dimensional information of
  ductwork before and after sections are removed.
  Falk PLI then can gather information on the new
  pieces to be installed. Creating 3D models of the
  pieces allows Falk PLI to assist our clients in
  making necessary adjustments to allow for a fit
  on the first lift. This work flow expedites the
  normal process of lift/check/adjust until the fit
  is correct. By adjusting the pieces on the
  ground, we give our clients a quality
  construction that has never been done before.

11
Sample Scan Work

• Oil Rig
• Falk PLI was asked to gather structural
  information to determine if a newly installed top
  drive was defective or if the structure it
  operates on was out of tolerance.

• Falk PLI gathered information to analyze the
  dolly rails and derrick structure. The
  information was gathered at several positions to
  determine the unusual failure of the top drive.

12
Sample Scan Work

• Plumbness/Flatness reports
• The points gathered from scanning are made into a
  3D surface, from which, a grid is generated to
  report the deviations of the wall.

13
Sample Scan Work

• Plumbness/Flatness Reports
• Ability to gather information inside smaller
  areas because of no hands on gathering system.

14
Sample Scan Work

• 3-dimensional modeling of an entire unit for
  determination of pipe routing

15
A Need for Precision

• Some clients need precise surveying
• Elevations within 0.005
• Alignments within 0.005
• Determination of equipment location within 0.005
• Falk PLI has a solution!
• Faro Tracker measures 3-dimensional coordinates
  at /- 0.001.

16
Falk PLI Laser Trackers

• Falk PLI understands and can meet our clients
  need for precision.
• Utilize Five Faro Trackers
• Measure /- 0.001
• Allows 3D alignment survey from one position
  relative to level, reference lines, planar
  reference lines, or radial reference lines.

17
How Laser Trackers Work

• Emit a laser that locks onto the center of an
  SMR
• The tracker has the robotic ability to follow the
  SMR as long as the SMR is aimed at the tracker
  and there is no direct inference in the beam
• Use of nests for tracker positioning
• 3 points of contact
• Best-fit (least squares) position determination

18
Advantages of Laser Trackers

• Repeatability
• Accuracy
• Dynamic Surveying
• Can gather information as the SMR is moving
• Assists in adjustments
• Determination of high/low points along a path
• Gather information for 3D alignments from one
  setup
• Fast re-survey after adjustments
• Ability to work in multiple coordinate systems
  simultaneously with no additional setups

19
Typical Falk PLI Tracker Work

• Industrial
• Caster alignment/replacement
• Equipment Alignment
• Foil Mills
• Galvanizing Lines
• Hot Strip Mills
• Pickle Lines
• Roll chock surveys
• Tandem/Temper Mills

20
Sample Tracker Work

• Roll Chock Surveys
• Verify distance of liners to the roll centerline.

21
Sample Tracker Work

• Mill Housings
• Verify distance on vertical liners from a
  determined centerline of mill stand.

22
Sample Tracker Work

• Caster Alignment
• Set oscillators
• Segment verification
• Determine best-fit radius point of caster based
  on segment pads
• Verify rolls, cams, pins
• Set permanent control (tracker plugs) for future
  verification surveys or adjustments

23
Falk PLI Goals

• Falk PLI prides itself on continuing to meet the
  demands of our clients through traditional
  surveying techniques and by continuing to plan
  and develop for a clients future surveying needs.
• Reduce re-work and expedite maintenance/constructi
  on on all jobs.
