Did you know?

Safe Software and Consortech have been partners for over 10 years.

We are SAFE SOFTWARE - data lovers and the makers of

FME. What’s FME?

A powerful integration engine that can be deployed by Desktop, Server, or Cloud. Check out www.safe.com for a 2 minute demo.

Why use BIM?

➔ Digital representation of infrastructure:

both building information and 3D

➔ Includes descriptive info (dimensions,

materials, manufacturers, etc.)

➔ Aids in proper design, construction,

operation, maintenance & updates

➔ Drawback: files size and complexity

make data difficult to repurpose

Why use GIS?

➔ Map and analyze geographic features

➔ Uses location and imagery

➔ Conveys data on a large scale

➔ Data models, attributes, simple geometries, and domains

Why extract from BIM?➔ Visualization

planning, site suitability

➔ 2D floor plansrouting, maintenance

➔ Analysisspace management: scheduling / leasing, energy / HVAC

➔ Construction managementas built vs design

➔ Facilities management maintain and replace components, work plans, reporting

➔ Updates keep BIM current, add reference links

BIM Challenges➔ BIM is too complex for most

GIS applications➔ Data model differences and

gaps object vs relational➔ Limited geo-referencing➔ File size / instanced

geometries➔ Schema mapping

which source feature types match GIS ones

➔ External references

How Can FME Help?

BIM data is very complex.

BIM Software Exports

- Overly complex (IFC)

- Overly simplified (DWG)

With FME

- Keep info you need

- Discard info you don’t

§ First Steps towards BIM §  CAD to GIS for BIM with FME §  Sharepoint to Vault with FME

§ Role of FME in BIM §  BIM for Infrastructure §  BIM for Buildings

Design Tools Integrators Information Management

An Airport is like a City

• Manage real-estate

•  Large CAD inventory, all 2D

•  Sharepoint document management system •  Difficulties managing CAD specifics such as reference drawings

An Airport is like a City

•  Difficult to share plans across business lines •  Maintenance •  Operations •  Security •  Etc.

Objectives for BIM

ü Use BIM in both their construction projects and in internal management ü  Long-term: Integrate with asset and facilities management solution (SAP)

Challenges

•  The main challenge is moving data into different systems

Role of FME in CAD to GIS

Analysis Conversion Validation

FME was used at multiple steps

Analysis

• FME inventoried each drawing •  Layer names •  Object Types (lines, text, blocks…) •  Object Counts

Conversion

Example conversion (lines)

1. Read DWG

2. Angle Checking and Text matching by proximity 5. Write to Database

4. Prepare Attributes

6. Reporting

b) Extra validation a) Layers to do manually

Conversion Challenges

• Attribute mining based on proximity

• Matching text values to a domain value

• Keeping the Data Freeze short

Angle Calculation

• Match

Angle Calculation

Domain Challenge

Quality Control

• Validated counts of features that arrived in database against number expected.

• Validated attribute matches, and texts that were unmatched

Benefits of using FME

•  Restructuring (parsing layers names, text matching)

•  Validation and Reporting

•  Simulation

VAULT MIGRATION

Vault Implementation

Migration from Sharepoint to Autodesk Vault

Pre-migration conditions

•  Situation before Vault implementation

• Number of data editors: ~ 10

• Number who consult plans: 150-200

• Number who will comment plans: 50

• Number of plans that need to be migrated from Sharepoint:~ 40 000

Analysis

•  Sharepoint Database

•  Files are in blobs •  Metadata in different columns •  No plan history maintained

•  Vault Database

•  The first database conversion simulated in our office •  Files are stored as DWG in a file directory structure

§  Client wanted to maintain same file structure

Solution

• Used FME to extract the data from Sharepoint and load the metadata into Vault

Files

Metadata FFS

Extraction from Sharepoint

1.  to FFS Read content ID

Read XML Field

Write metadata to FFS

Domains process validation

Load into Vault

Read metadata FFS File

Read attribute definition from Vault

Generate specific insertion query

Generate importation report

Read related info from Vault

Challenges

•  The attribute definitions in Sharepoint are embedded in XML stored in the database

•  Colonne de type sql_variant pour la valeur des attributs dans Vault (générer le code d’insertion plutôt qu’utiliser un simple feature writer)

Benefits of FME

•  TurnKey solution

•  Avoided manual loading, minimizing risk

•  The translation could be simulated

WHAT’S NEXT WITH BIM?

BIM Continuation

• There are several ways that FME can help going forward

•  Interoperability between different BIM tools

BIM for Infrastructure Potential

• There are several ways that FME can help with future potential BIM for Infrastructure Workflows •  Prepping data for InfraWorks

§  Gathering different terrain data §  Integrating different 3D data

•  Extracting Infrastructure data to do Civil Design

•  Automate Civil 3D to GIS

Moving to BIM for Buildings

• Compare Revit files

Moving to BIM for Buildings

• Create lighter Building models for Integration into InfraWorks

BIM / GIS / CAD integration workflows in FME

Tip

Download FME 2016 for the latest support in formats and protocols.

Plus the new FME Workbench functionality helps you output the data whenever and however you need it.

GIS <-> BIM: Transformation

Attributes● Schema mapping● Resolving relationships

Geometry● Geo-referencing● Conversion / Extrusion

(2D to 3D)● Instances● Appearances● Validation

BIM Formats

Reading:● Autodesk Revit, FBX● IFC● CityGML, IndoorGML (BIM-lite)

Writing:● IFC● CityGML (ADE’s), IndoorGML

BIM: Key Techniques

A starting point BIM model can be quickly created from GIS

FME can extract IFC to Excel. Edits can be merged back into IFC.

Revit Data Views in FME produce 3D data ready for use.

Removing detail is necessary for efficient viewing.

Hierarchies are complex but can be tamed. Understanding geometry hierarchy informs workflow design.

GQuery (Geometry XQuery) empowers transformers for BIM

Problem: Create Slim-Bim from CAD & GIS

Solution

IFC Result: Create Slim-Bim from CAD & GIS

Key Takeaways

● A starting point BIM model can be quickly created from GIS

● IFCProperty Set Definitions are created in the workspace using

transformers

● IFC Property Sets are stored as part of the geometries in IFC and

are populated from GIS attributes

Problem: Reduce BIM Data Volumes

Solution

I-35 Bridge Workflow: Revit to linked CityGML

1. Bridge BIM created in Revit by DBI Architects

2. Revit Extension - FME Exporter - creates .rvz file

3. FME Workspace: Revit .rvz to CityGML conversion with embedded component uri’s

4. VirtualCitySystems imports CityGML into their 3D City Database

5. RevMac – uses linked data tools / rdf to analyze embedded component data

GeometryValidator for 3D

• Checks for solids with inverted faces, dangling surfaces, unsealed solids, etc

• Flag errors with descriptions and locations

• Chain multiple validators to isolate problems of interest (e.g 2d before 3d)

• Repair option

FME Server: Publish BIM / 3D to the Web

SummaryBIM is about information management through the building life cycle from planning through maintenance, not just design

Leveraging BIM’s value requires integration with CAD and GIS systems

This presents challenges that FME helps address with BIM - CAD - GIS workflows:

● Load from / export to any CAD, GIS or 3D format

● Transform / Validate schema, geometry and semantics

● Extract and filter from BIM – just what you need

● Automate enterprise services and updates

● Publish BIM data to client and mobile friendly formats
