BIM in Practice -
Advantages and
Obstacles for
Structural Engineers

BIM- Where we are?
 The Government Construction Strategy was published by the Cabinet
office on 31 May 2011. The report announced the Governments
intention to require: collaborative 3D BIM (with all project and asset
information, documentation and data being electronic) on its projects
by 2016.

Standards overview
 PAS 1192 Collaborative production of architectural, engineering and
Construction information – Code of practice
 PAS 1192-2 Specification for information management for the
capital/delivery phase of construction projects using Building
Information Modelling.
 PAS 1192-3, offers guidance on the use and maintenance of the asset
information model (AIM) to support the planned preventative
maintenance programme and the portfolio management activity for the
life of the asset.
 BS 1192-4:2014 - Collaborative production of information. Fulfilling
employer’s information exchange requirements using COBie. Code of
practice
 PAS 1192-5:2015 Specification for security-minded building
information modelling, digital built environments and smart asset
management

Legal
 BUILDING INFORMATION MODEL (BIM) PROTOCOL CIC/BIM Pro

Employer's Information Requirement
 The Employer’s Information Requirements (EIR) form part
of the appointment and tender documents on a BIM
Project.

BIM roles and responsibilities
 BIM users  BIM professionals:
 BIM Modeller
 BIM Analyst
 BIM Application Developer
 Modelling Specialist
 BIM Facilitator
 BIM Consultant
 BIM Researcher
 BIM Manager

IFC - Industry Foundation Classes
 It is a platform neutral, open file format specification that is not
controlled by a single vendor or group of vendors. It is an object-based
file format with a data model developed by building SMART (formerly
the International Alliance for Interoperability, IAI) to facilitate
interoperability in the architecture, engineering and construction (AEC)
industry, and is a commonly used collaboration format in Building
information modelling (BIM) based projects. The IFC model
specification is open and available. It is registered by ISO and is an
official International Standard ISO 16739:2013.

COBie
 Construction-Operations Building Information Exchange
helps organising information about new and existing facilities. It is general
enough that it can be used to document both Buildings and Infrastructure
assets. It is simple enough that it can be transmitted using a spreadsheet
like MS-Excel. It is a means of sharing structured information, just like
CDM and BIM.
 There are currently 700 templates available in COBie, HTML,
XHTML, IFC and IFCXML formats at
http://www.bimtaskgroup.org/cobie/

COBie
 Yellow = a required field
 Green = optional field
 Orange = reference to other or pick list
 Purple = external reference
 Green = if specified required
 Grey = secondary info if required
COBie Drop 1: Requirement and constraints, massing model
COBie Drop 2: Outline solution
COBie Drop 3: Construction Information
COBie Drop 4: Operation and maintenance
COBie Drop 5 (or more): Operation and maintenance post occupancy

COBie
 The BIM Task Group states “BS 1192-4:2014 defines expectations for
the exchange of information throughout the lifecycle of a Facility. The
use of COBie ensures that information can be prepared and used
without the need for knowledge of the sending and receiving applications
or databases. It ensures that the information exchange can be reviewed
and validated for compliance, continuity and completeness.” BS 1192-4
also recommends a number of additional fields that can be added at
different levels of the model to provide further information within the
Attributes data of a COBie output.
 Component requires 2 core pieces of data as a minimum – Name and
Description. Each Component must have a unique Name. For example
for doors the Name field may be Door 101, Door 102, Door 103 etc

BIM benefits for structural engineers
 With this technology, structural designs can be incorporated early in the
building process, so that design interferences can be kept to the
minimum when construction work begins.
 Bidirectional connections to analysis applications from industry and
regional associates can help to cut down on coordination errors as well
as improve accuracy levels. In addition to improving coordination
between extended teams, the technology helps to efficiently
incorporate and accommodate design alterations as and when they
occur.
 The power to envision a building project prior to construction increases
productivity. BIM leads to lesser man-hours in every structural design
which, in turn, translates into low development costs. This feature can
also result in fewer billable hours.
