This document summarizes a presentation on geospatial BIM (GeoBIM). The presentation discusses: 1) The role of geospatial data in design, construction, and maintenance of built assets including its use on mega-projects and for planning and decision making. 2) How GeoBIM and BIM convergence can support intelligent location information and urban density. 3) Future opportunities for GeoBIM including its role in digital transformation, smart cities, and emerging technologies like IoT, big data, and artificial intelligence.

16. Why BIM?
• What are the drivers?
• Government Construction Strategy (2011)
• Construction 2025: strategy (2013)
• ‘BIM Level 2’ Government Mandate
• Time saved on finding information
• Hand-over / Hand-back
• Align with CDM information requirements
• Clash avoidance (not clash detection)
• Avoid rework
• De-risk projects
• Improve reputation – trusted information
• Provide added value to your clients

The Challenges We Face

25. How does GIS add value to BIM?
• Persuading design
teams to utilise (at any
level) what GIS type
data can bring to a
project:
• Align project to World to
other coordinates
system
• Provides ability to utilise:
– Ground topography
– Existing buildings / asset data
– Transport and services data
– Linear assets
– Augmented reality
– Laser scans
– Rights of light

26. BIM & GIS
• Simplification of complex datasets
• Spatial Co-ordination and Spatial are key
• Context, relationships
• Focus on information
• Focus on metadata
• Master Data Management (MDM)

27. King’s Cross GIS

29. When is a Polygon a Polygon?

30. When is a polygon a polygon?
1.[ESRI software] In ArcGIS software, a shape defined by one or
more paths, in which a path is a series of connected segments. If a
polyline has more than one path (a multipart polyline), the paths may
either branch or be discontinuous.
1.[data models] On a map, a closed shape defined by a connected
sequence of x,y coordinate pairs, where the first and last coordinate
pair are the same and all other pairs are unique.
2.[ESRI software] In ArcGIS software, a shape defined by one or
more rings, where a ring is a path that starts and ends at the same
point.
If a polygon has more than one ring, the rings may be separate from
one another or they may nest inside one another, but they may not
overlap.
Polygon
The POLYGON command allows you to create regular polygons
(polygons with equal sides and angles).
--Prompt: Number of sides: Type in a value for the number of sides
for the polygon.
--Prompt: Edge/ <Center of polygon>: Select the location for the polygon's center with an
Absolute Coordinate, a Relative Rectangular Coordinate,
a Relative Polar Coordinates, or an Osnap and press Enter.
Polyline (closed)
The PLINE command allows you to create "grouped" objects that can be
extruded, given line width on the screen, and can contain arc segments. Close
- Connect the last segment of a pline with the first.
Length - Draws a pline segment at the same angle as and connected to the previous
segment using a length you specify. If the last element was an Arc, the new segment
is tangent to the Arc.

32. How to tackle the language challenge?
Slide 32

33. Remember
• Try to keep things simple
• Most people won’t even know what
‘geospatial’ means
• Even across the ‘geo’ sector we have
differing terms
• Some people just don’t understand
plans
• Try to not go to detail initially

34. The big challenge is communication
Slide 34
• Between systems
• Between data formats
• Between organisations
• Between disciplines
• Between different roles
How are your
cross-discipline
communication
skills?

35. GeoBIM and Mega-projects
►Use on mega-projects
►Use on not-so-mega projects

40. Relationship between GIS and Maximo
GIS shows assets &
work orders etc..
geographically
Maximo sits on Oracle
database, geometry
held in spatial
cartridge, asset and
work order data
geometry
Maximo
Asset data
Work orders
Maximo
Applications – Work
Management &
Asset Register
Access databases, with asset data
(being migrated into Maximo wherever possible)

41. • Network design rationale:
– Station to Station defines a unique asset/network segment.
– Each asset/network segment has detailed characteristics with an
associated linear measure.
– Track Asset Register and Fault Management Grouped into:
• Check Rail
• Conductor Rail
• P&C (Switches)
• Running Rail
• Sleepers
• Track Support, Drainage and Formation
• Lineside Equipment
• Off Track Items
Requirements - Storing of track linear assets details
in Asset Management System
0m 100m 200m
Rail type LH
Sleeper type
Ballast type limestone
wooden
flat bottom
granite
concrete
bullhead

42. Track Assets in Maximo
Track linear asset details - rail type, age, ballast , rails joints etc. for
one track section held with start and stop positions along the asset.
