Quality Assurance
with Laser Scanning in Construction Management
and Revamp Projects Matthew Tait, assistant
Professor, Department of Geomatics Engineering,
University of Calgary Petrocanada and Canadian Natural
Resources are both examining how 3D laser scanning
data might improve their construction methods
in the Albertan oil sands development to benefit
the lifecycle of these multi-billion-dollar
engineering projects. However, the laser scanning
data must be reliable if engineers are to base
expensive decisions on it. While other 3D capture
methods like digital photogrammetry have resulted
in some negative experiences for owner companies,
fortunately some lessons have been learned over
this period, and laser scanning standards are
now being developed, but such benchmarking alone
is not the total solution for quality assurance
in 3D applications. This talk will cover the
primary causes of construction productivity
problems and the requirements for retrofitting
work, and how laser scanning technology can
solve some of these issues. How to ensure the
quality of the work in a continually varying
environment, and how the engineers can interpret
these 3D observations meaningfully will be explored.
Finally, a vision of the future of laser scanning
technology will be presented for discussion.

Choosing Laser Scanning
Over Traditional Methods of Manual Documentation Alba Lee Smith, lead
project designer, Hanover Company
Projects teams face a number of challenges when
attempting to meet or beat project budget or schedule.
Some of the most substantial include significant
field time and the time and cost of redrawing
or remodeling existing field conditions data,
the number of field welds due to inaccurate or
unknown tie points and unidentified interferences
during design from inaccurate or limited existing
field conditions data. What would the impact be
on field and remodeling time if your team could
access facility on their individual workstations
for virtual site visits? How would field welds
be affected if you could access a detailed report
containing an image, coordinates and even flange
information for each tie point to use as a basis
for design? Finally, what would the impact on
interferences be if you could clash proposed designs
against actual field conditions on their workstations
or could be provided with detailed reports containing
an image, coordinates and suggested resolutions
for any interferences before the designs were
issued for construction? This presentation will
address how laser scanning be used to answer these
questions and the associated benefits.

Case Studies: Remarkable Results and Real
ROI Chris Comardo, design
supervisor, special projects, Mustang Engineering
One laser survey on a project with 70-100 tie-ins
reduced the percentage of errors to less than
1%, when similar projects with no laser scanning
had error rates of 5% to 10%. At a Gulf Coast
refinery, an upgrade project used to require
8-10 people for nearly 6 months to take measurements
manually, but with laser scanning, only a few
short trips to the field were necessary, which
was much safer for the employees involved. At
one Equatorial Guinea project, the laser scanning
crew took only one week, as opposed to 6-8 weeks
for manual data gathering. Such phenomenal results
make laser scanning worth the investment.

Conoco-Phillips' Tyonek
Platform Retrofit Project Bill Beam, plant sales
executive, Western USA, Leica Geosystems HDS
VECO Alaska was tasked with upgrading several
major pieces of equipment for ConocoPhilips Alaska
to reduce particulates in produced gas for better
transmission through the pipeline. The project
schedule was tight, shutdown time minimization
was critical, and accurate drawing information
was not available. VECO selected 3D laser scanning,
Bentley CloudWorx and Bentley 3D AutoPLANT for
this important project. VECO was able to design
to true as-built conditions and check for interferences
in an extremely congested area. When issues were
discovered using 3D images, VECO was able to promptly
communicate with field operators and quickly resolve
any problems.
VECO was honored to receive a BE Success Award
in May 2005 at the Bentley International User
Conference in Baltimore for this successful project.
4:00 - 4:45 PM
Integrating Point Cloud Data with CAD Design
Software Ken Dooley, regional
manager, Trimble Navigation, Power, Process
and Plant
Advances in technology now allow point cloud
data generated during laser surveys to be used
directly with leading CAD and design tools.
What is the appropriate IT infrastructure needed
for this? What is the workflow to incorporate
laser scanning data into the design and visualization
programs? How does an engineer use the laser
model to optimize the revamp operations and
reduce field rework? What does the future hold
for laser scanning technology, and what data
standards are being developed?
