Why BIM?Setting the Context

T h e G o v e r n m e n t C o n s t r u c t i o n S t r a t e g y2 0 1 6 M a n d a t e

By April 2016 All centrally funded Government Departments will provide clear and complete “EIR’s” with all contracts

By October 2016All government departments will have the capability to electronically validate BIM information delivered from the supply chain

Departments will be making progressively more use of supply chain data for key business activities

What is BIM?Building Information Modelling

IT’S A PROCESSW h a t i s B I M ?

BIM Task Group Definition:‘BIM is essentially value-creating collaboration through the entire life cycle of an asset, underpinned by the creation, collation and exchange of shared 3D models and intelligent, structured data attached to them.’

Simple Definition:‘Building Information Modelling is about everyone understanding a building through the use of a digital model.’

Even Simpler Definition:‘We build it in the computer before building it in real life.’

W h a t i s B I M ?

D i g i t a l D i m e n s i o n s

3D BIM: modelling with 3 dimensional data - the basic BIM

4D BIM: the addition of construction sequencing within the modelling to support programming analysis

5D BIM: the addition of ‘cost’ data to aid cost modelling.

6D BIM: the inclusion of facilities management specific data.

A single model can hold a wide variety of information

THE BIM

A fundamental difference from 2D drafting is the use of intelligent objects that know what they are how they should perform and who are their manufacturers.

How do we deliver BIM?

B I M M a t u r i t y L e v e l s

PAS 1192 calls for an iterative approach to design and data production. Clients are able to draw down information to inform financial decisions prior to commencement on site when changes have less financial implications.

In this image, the design coordinator has combined (federated) all the models on the project and performed a clash detection. The syphonic drainage here is clashing with the ductwork from the MEP package allowing these to be foreseen and design out before works begin on site.

BIM for the client?

E m p l o y e r s I n f o r m a t i o n Re q u i r e m e n t s ( E I R )The Employer’s Information Requirements (EIR) form part of the appointment and tender documents on a BIM Project.

Information Requirements need to be defined as part of the Employer’s Requirements. 

The content of the EIR covers three areas:

• Technical – details of software platforms, definitions of levels of detail etc

• Management – details of management processes to be adopted in connection with BIM on a project

• Commercial – details of BIM Model deliverables, timing of data drops and definitions of information purposes

PAS 1192-5 specifies the processes that will assist organisations in identifying and implementing appropriate and proportionate measures to reduce the risk of loss or disclosure of information which could impact on the safety and security of:

• personnel and other occupants or users of the built asset and its services;

• the built asset itself;

• asset information; and/or

• the benefits the built asset exists to deliver

PA S 1 1 9 2 - 3 : 2 0 1 4 - O P E X

PAS1192-3 specifies information for the operational phase of assets using building information modelling:

• Relationship to PAS55-1:2008 – Asset Management

• Asset Information Model (AIM)

• Asset Information Requirements (AIR)

• Organizational Information Requirements (OIR)

C o m m o n D a t a E n v i r o n m e n t ( C D E )

 A BIM object is a combination of many things:

• Information content that defines a product

• Product properties, such as thermal performance

• Geometry representing the product’s physical characteristics

• Visualisation data giving the object a recognisable appearance

• Functional data, such as detection zones, that enables the object to be positioned and behave in the same manner as the product itself.

• Ongoing maintenance - logistics

• Replacement parts

• Servicing

• De-commissioning

• Running costs analysis

• Construction Operations Building Information Exchange

• Large spreadsheet extracted from the model

• Some parameters completed by the supply chain

• Managed by the Information Manager

• Allows integration with CAFM

• Key requirement of Level 2 BIM

C O B i e

Reduced costs as a result of the automated transfer of accurate, complete and unambiguous information at asset handover and during transfer of operation from one service provider to another.

Better awareness of the operational and maintenance needs of assets.

Better decisions regarding operation and maintenance expenditure based on actual asset performance and status.

Better identification of poor performance, faults and impending failure by providing a home for data from dynamic measuring and condition sensing devices.

Better organisation planning and strategic planning by having more complete and accurate asset information.

Better information quality as a result of the automated verification introduced by the governance requirements.
