DESCRIPTION
Whether you are embarking on a new facility, addition, or historic renovation, laser scanning can provide detailed information quickly that can be critical to the success of your project. Laser scanning allows the project team to cost effectively capture existing facility and field conditions to ultimately deliver value through increased certainty, quality, and efficiency. Please join us for a presentation as we share some of our success stories and answer questions you may have about laser scanning.

Agenda
Mortenson Construction
• Family Owned firm founded in 1954
• Building in Chicago for over 25 Years
• 26th Largest Construction Firm (ENR)
• $3 Billion annual revenues
• Zero lost time injuries in 2013
Laser Scanning - Definition
• 3D Laser Scanning is a means of rapidly collecting detailed and accurate as-built data.
• A 3D Laser Scanner emits a laser beam that “sweeps across” a target object gathering millions of measurements.
• This data can be viewed, navigated and analyzed much like a 3D model created in a traditional CAD system.
Why does Mortenson Laser Scan???
Scanning is the most time effective way of capturing a three –
dimensional moment of existing objects and structures.

Started with only Point
Cloud – Modeling with
indexed point cloud in
Revit Structure

Converted into
BIM – Rendered

This is how Mortenson is leading the
Construction Industry in Laser Scanning…

Workflow
Integrated Work Plan
• Plan the work
• Determine how many setups are required
• Determine with the client what deliverable is required (Point Cloud / Revit model / Navisworks model)
• Review plan with the design team
• WORK THE PLAN!
Estimate Example
• IWP determines how much time will be required to complete scan project.
•Communication tool for scheduling craft workers and ordering equipment from the yard
•Proper planning for travel and gives the internal client idea of what travel will cost
•Review the estimate with team before approval
Project Geography•Scanned over 70
projects for internal projects, architects, and engineering firms
•We have traveled to over 12 different states

Complexity Scale
• Planning = Logistics, scheduling, travel, estimating, & meetings
• Capture = Targeting, survey, building control, & scanning
• Processing = Registration, stitching, indexing into Revit, & uploading to WebShare

What is the VALUE added to the project???
Mortensen staff worked with
the design and construction
team to verify pipe and
conduit routing in the
model prior to construction,
which saved the project both
time and money. The
accuracy of their model
was very good and the
installation went well and
without issues.
