Leveraging Laser Scanning Point Cloud BIM
(Virtual Reality) to Provide Enhanced Customer
Service

What is Scan to BIM?

• SCAN to BIM Provides Single Reference File in
• Precise Digital Model
• Facilitates Customers To
• Manage, Benchmark, Synchronize Supervise
• Incoming Data
• Obtain Verified, Reliable Reference Data in Real
  Time
• Manage Change, Plan Ahead Optimize Performance
• of New Buildings

Laser Scan to BIM Uniqueness

• Design Build is one of the most challenging
  projects for Engineers, Consultants
• Stakeholders.
• Laser Scanning to BIM technology convinces
  Stakeholders by yielding cost
• effective result for Major Construction
  projects.
• The whole process facilitates stakeholders in
  Optimizing Quality Maintaining
• Project Progress as per Schedule.

Working Methodology

• 3D Laser Scanning from Faro Focus S Scanner
• Registration of Scans using Autodesk Recap Pro
• Point Cloud Model Creation from Laser Scans in
  Global Coordinates
• Progress Model Creation from Laser Scanning
• Construction QA/QC by Comparing the As-Built to
  As-Design Models
• Stockpile Volume Measurement from Laser Scanning
  using
• CIVIL 3D Bentley

Strategy - Successful Implementation of
LaserScanning to BIM

• Value Proposition/Technology Leverage
• BIM Point Cloud helps accurate 3d model creation
  for renovation extension from scan data,
  allowing reliability quality assurance
• During renovation, Construction Scan to BIM Model
  provides an enhanced platform for preparing
  detailed design work
• Improved transparency streamlined communication
  with 3D visualization facilitate decision making
• Eliminates work stoppage rework by checking
  accuracy completeness of 3D Model from scan
  data, saving time money for clients

Work Process 3C Formula

• CAPTURE- Using laser scanners, a site is scanned
  detailed set of data or 'points' is captured
  for further processing
• COMPUTE- Using laser scanning to BIM software,
  scan data is automatically registered, stitched
  into coordinate system, cleaned up analyzed.
  The final product is a point cloud ready for BIM
  authoring tools
• CREATE- Design, knowing that the base
  information is a model up-to-date data of actual
  site conditions

7
Progress Model Creation from Laser Scanning

• Construction QA/QC Comparing As-Built to
  As-design Models
• The uses of point cloud model have drastically
  increased the QA/QC process of construction with
  As-design models.
• As-Design As-Built Models in Autodesk
  Navisworks are compared with 2 methods-
• Manual Comparison of Both Models
• Using Some Advance Plugin(ClearEdge3D) to check
  Standard Deviation between Both Models

Process Solution

• Stockpile Volume Measurement from Laser Scanning
• using CIVIL 3D Bentley
• Measurement of Stockpile Quantity using Laser
  Scanning plays an important role in Tracking
  Project Cost on Timely Basis
• Invoicing of Aggregate Stock Processed as per
  Volume by Laser Scanning
• Internal Schedule for Scanning Includes Stockpile
  Scanning at the end of every month to check the
  Quantity of Stock

9
Triangulation Surface Volume of Stockpile

• Civil 3D software creates surfaces with the
  orientation of points in 3 Dimensional Point
  Cloud Model
• Calculates Volume with Triangulation Algorithm

10
Issue - Challenges Faced by Current Construction
Professionals

• The current practice for capturing existing field
  conditions is tedious, manual, analog and
  inaccurate, leading to costly rework
• Be it a building renovation or large-scale
  infrastructure project, the surveying
  documentation cannot be accurately captured in a
  simple efficient way
• This is a time-consuming, manual inefficient
  process, where one
• is left with site sections site that cannot
  be measured accurately

11
Overcoming Challenges with Point Cloud BIM,
Meeting Industry Needs

• With an increase in BIM usage, there will be a
  knock-on effect, generating more requests for 3D
  surveys, resulting in more laser scanner use with
  point cloud deliverables
• The growth of BIM will play a significant part in
  the adoption of point clouds across non-survey
  disciplines
• Laser Scanning can help to create on an older
  structure with static image documentation of
  existing conditions. It is difficult to check
  update the old blueprints manually. Laser
  scanning can help to work on these projects with
  an alternative and better approach

Key Takeaways

• ACCURACY - With photo-to-point cloud creation
  laser scanning, Realty Capture delivers
  incredible detail, preventing costly rework
  later. Each point captured is mapped on to a
  coordinate system, for an intelligent survey
  output, ready to export as per need
• BUILT-IN EFFICIENCY - A site scan immediately
  creates digitized 3D replica accelerating the
  surveying documentation, reducing labor costs.
  Reality Capture creates efficient workflows,
  enhancing productivity reducing time manual
  effort
• LESS MANUAL WORK - Digitized data provides
  analytical connected insight, surveying
  specialists can use time to point out
  opportunities/pain points of design
  construction teams
• DESIGNING IN 3D - Realty Capture is a bridge
  between raw site conditions intelligent BIM,
  helping project teams to avoid manual design
  documentation rework, reducing delay in
  construction design schedules by 30

13
Long Term Benefits - Sustainability Gains the
Initiative could bring

• 3D scanning provides average person an ability to
  customize almost anything they want
• With more affordable price points, 3D scanning
  will become more accessible to consumers for
  personal use
• Future Outlook - Global 3d Laser Scanning is set
  to boom in the coming years -The 3D scanner
  market is expected to grow from USD 3.41 Billion
  in 2016 to USD 5.90 Billion by 2023, at a CAGR of
  7.8 during the forecast period.
