A less-than-compelling deliverable can cause permanent damage to the relationship between provider and customer. As those customers demand better quality at faster speeds and lower costs, Service providers need to strike a fine balance between the those three dimensions. Improving along one can’t come at the expense of the others. During our March webinar hear from an Engineering and a Surveying service providers who are leveraging Building Information Modeling (BIM) and technology to improve the customer relationship across quality, speed and cost dimensions for scan-to-model projects. In doing so they’re increasing the value of their deliverable and their impact on the project delivery process. As a result, they’re delighting their customers and winning repeat business. Take a trip into the field and hear experiences from two active projects. Attend the webinar and you’ll learn: • The importance of ensuring highest levels of accuracy in a collaborative environment • How industry peers are ensuring and benefiting from automated workflows • Tips and tricks for increasing accuracy of BIM deliverables • Best practice data processing and modeling tips to speed your back office workflow Join laser scanning, modeling and BIM experts Daniel Niziolek of Ramboll UK and Les Carter of Cannon US share their experiences and best practices for capturing and accelerating scan-to-model workflows in case study format.

7. Commercial Building
Central London
Project Scope: Accurate as-built model for fitting in additional equipment

8. • Building renovation project
• Client was a Ramboll Building
Services team
• They designed original services,
but was built with major
differences to construction
drawings/models
• Client needed new design to fit
around what was actually built
• Brief was to survey and Revit
model the as-built environment

About the Project
Commercial Building Redevelopment

10. • Short timeframe – client needed
immediate start and fast
turnaround
• Took over from another survey
company who couldn’t meet the
deadlines
• Getting enough coverage of the
pipes and services in/out of
reach areas
Unique Challenges Faced
Commercial Building Redevelopment

11. Firm Name
• Z+F Imager 5010c scanner
• Active construction site –
safety and planning issues
• 33 scanner locations
• Over 3 billion points
• 1 day on site for 2 surveyors
• 1 day office post processing
(in Leica Cyclone)
• Target based registration
Field Collection Workflow

12. • 300 GB of data
• Process locally on SSD drives
• 1 modeler
• Approx. 8 days total modeling
time (6 in Edgewise and 2 in
Revit)
• Edgewise used for modeling
walls, pipes, columns and beams
• Revit used to model floor slab,
ceiling, plant (masses), windows
and doors
Back-office Modeling Workflow
Commercial Building Redevelopment

13. • Auto wall detection found vast
majority of walls
• Determines wall thickness if scan
data is on both sides, otherwise
default thickness
• Level extraction useful in Revit
• Window detection didn’t work
EdgeWise Building
EdgeWise in Action

14. • Used Pattern Extract wherever
possible
• Not a perfect structure and not
very repetitive
• Standard tools work great for
bracing / non-vertical / non-
horizontal members
• Biggest time-saving with
Edgewise Structure was sizing
beams and columns
EdgeWise Structure
EdgeWise in Action

15. • Some beams are fabricated from steel plate
• Model used for clashes/reference, not structural
• Decided to define custom I-Beam in Edgewise
• Tip: You need to include correct k value!

17. • Auto pipe extraction found majority
of the pipes
• Some manual work needed, but this
is pretty quick and easy
• Needed to manually extract about
25% additional pipes and
extend/connect those that were
found
• Tip: be methodical in moving around
the site – finish an area before
moving on
• Tip: For UK users, make sure you use
the US Metric Systems template

26. About the Project
Technology Academy Building
• 2-story Building Expansion and
retro-fit.
• Scan area: 34,000 ft2.
• Client; College District
• Provide point cloud and prepare
a REVIT Model.
• Client needed the updated “As-
Built” conditions of the building
• Required a high level of detail.

27. • Coordination of scanning during
ongoing construction operations
• Scanner locations obstructed by
equipment and construction
materials
• Dim lighting requiring battery
operated lights
Unique Challenges Faced
Technology Academy Building

28. • Smaller diameter pipe has to
have sufficient point cloud
coverage so It can be extracted
manually.
• More scans had to be taken due
to the density and size of the
piping.
• Creating the level of detail
needed in REVIT Model was a
key challenge.
Unique Challenges Faced
Technology Academy Building

29. • Dense structural features interfered
with the scanner line of site for the
piping
• 3D Modeling of unique non-standard
structural features
• Client required the model to show any
blocking and supports added as
additional structural reinforcement
during construction process.
Unique Challenges Faced
Technology Academy Building

30. Firm Name
• Created scanner location map for
each floor.
• On site field recon to verify site
conditions and access.
• Used FARO x330 Scanner.
• Used battery LED work lights in
some rooms for photo draped
color scans.
• Scans were performed during
ongoing construction. Required
close coordination with GC.
Field Collection Workflow
Pre-Planning

31. Firm Name
• Number of controlled scans: 134
• Field collection time: 7 days
• Existing multi story building with
drop ceilings, interior walls and
existing rooms.
• Project had to be in contractors
coordinate system.
• Registration software used: FARO
Scene
Field Collection Workflow
Field Operations

32. • Created Clear View and Recap
point clouds
• Working copies of point clouds
were stored locally on
workstations.
• Extracted walls, structure, and
piping in Edgewise.
• Point cloud and auto extraction
was ran overnight.
• “Minimizes potential errors in
human judgement”.
Back-office Modeling Workflow
Technology Academy Building

33. • 2 modelers worked together in
parallel.
• One working on mechanical
features and Revit model, and
the other working on Steel and
piping details.
• A great deal of user extraction of
smaller piping and custom
structural details was necessary.
Back-office Modeling Workflow
Technology Academy Building

34. • REVIT files were updated with
extracted elements.
• Wall openings and Custom
features were modeled in Revit
using a ReCap pointcloud.
• Revit project files were stored
on server location.
Back-office Modeling Workflow
Technology Academy Building

35. Firm Name
• Our Client needed a Revit
as-built which reflected
detailed “Reality Capture” of
the building.
• Finished Project was 244GB
of data.
• We also provided the full
registered point cloud as
Autodesk ReCap files.
Final Deliverables

36. Edgewise Workflow Time Savings
Technology Academy Building
• Old Workflow: 160+ hours
• Edgewise Workflow: 80 Hours
• By extracting walls, structure and
piping in Edgewise we achieved a
50% cost savings in the modeling
workflow.

37. • As for any project, the keys to
success are:
• A well defined scope of work and
a very specific and detailed
description of the level of details
to be shown in the CAD/Revit
Model.
• For this project:
• Highly detailed and “non-
standard” Structural features.
• Small diameter conduits.
• Non-standard HVAC features.
