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.

BIM- What do I need?

Training – information

Standards

MS-Excel

2D, 3D software

Material library

STANDARDS AND

REQUIREMENTS

Publicly Available 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

Employer's Information Requirement

The Employer’s Information Requirements (EIR) form

part of the appointment and tender documents on a

BIM Project.

The BIM Protocol

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

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.

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

SOFTWARE

Google - SketchUp pro

Google SketchUp Pro is used to

quickly create accurate 3D

models for pursuit and marketing,

preliminary estimation, detailing,

site logistics and staging, design

and construction validation,

sequencing and line-of-sight

analysis. It enables collaboration

and communication between the

various stakeholders on a project.

SketchUp pro imports 3D models

in DAE (COLLADA), 3DS, KMZ

and DEM formats and DXFs and

DWGs and IFC

€657.00 per license

SketchUp is a great software for

creating 3D or 2D geometry that can

then be imported into analysis

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.

Technology helps to efficiently incorporate and accommodate design

alterations as and when they occur.

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.
