Overview

Context: Collection of (geo-)dataData overloadInformation-driven decisionsOpen, Big, Linked3D CitiesOpen standards (information models)Importance of underground infrastructures

Overview

Goal: Integration of information via- As-designed and As-built- 2D (GIS) turns 3D (or 4- or 5D)- Underground- Rich semantics- Asset management

Examples: BIM @ RotterdamPort of RotterdamRotterdam 3D

Background: goals of GIM

§ Information is consistent and managable

§Good quality of information

§Object-oriented information & semantics

§Collected once, used many times

§Open data standards for information models, national and

international

§Any number of representations (GIS, maps and models) and

formats (shape, XML, etc..)

Aspects of BIM in projects

§Systems engineering for specification of requirements

(including stakeholder-analysis)

§Modelling surroundings (included in BIM) from geo

§3D design and engineering

§Tender

§Build

§Delivery of information to Asset Management Systems

Asset management @ Public Spaces

Asset management @ Public Spaces

Traditional outcome:§Management, Facility, Maintenance§Tenders§Operational programs

But now:§ Domain specific becomes generic§ Geo-information and asset information together are a

source for BIM

New ideas on collection and sharing (data to information)

Rotterdam 3D – Approach

3D should be an

integral part of

processes within the

city.

Which includes BIM

and Asset

Management.
