BIM: Why?

Previous Studies have led Government towards BIM:

• Coordinating Working Drawings Report by BRE (1976) Noted: 

“unclear/missing Project Information as main cause for mistakes”

• Constructing the Team by HMG (1994) Noted:

“The Construction Industry is ‘ineffective’ ‘adversarial’ and ‘fragmented’

• Rethinking Construction by Sir John Egan (1998) Noted:

“Industry should create an integrated project process”

BIM: Why?

• Key Government Strategy – BIS BIM Strategy 2011

• “Government as a Client can derive significant improvements in cost, value and carbon performance through the use of open shareable asset information”

• Government will require fully collaborative BIM Level 2 by 04 April 2016

BIM: What.The Key Documents we use

BIM: What.Roles and Responsibilities

BIM: What.The information delivery cycle

BIM: What.

BIM: What.What BIM Software do HOP use?

BIM: How.HOP’s First Revit Project: Old Portsmouth – 2007!

BIM: How.HOP’s First Revit Project: Old Portsmouth

BIM: How.Drawings produced 

from Model

BIM: How.What Happened Next…………… Lonely BIM!

The Amex Stadium: 2008

BIM: How.

Using different software to help ‘bridge the gap’!

The Amex Stadium: 2008

Groundworks

Civils 3D

Structure

Revit

BIM: How.Lonely BIM… Structure only.

Northbrook College – Phase 1: 2010

BIM: How.Then we started COLLABORATING…. The BIM Way!

Northbrook College – Phase 2: 2013

BIM: How.Working with other Designers using Revit…..

Northbrook College – Phase 3: 2014

BIM: How.Key Benefits of why we started using Revit/BIM:

• Coordinated documents and designs with other teamdisciplines

• Production of Design Prototype… rich in data• Integrated Modelling – analytical and draughting• Accuracy of quantification / costing / measurements• Supports design investigation to study multiple

alternatives simultaneously• Analysis (Space, Structure, cut and fill, etc.)• Clash detection with Coordinated model• Drawing production quality (3D and images)

BIM: How.Key Revit/BIM Lessons Learnt.

• Make sure you follow the process and produce a BIM Execution Plan (BEP) before any design.

• Ideally all Designers work on the same software platform.

• Detail attribute information as the model as it is produced.

• We have found the process suits larger framed projects,  where there is a more defined split of design disciplines.

• Hold regular BIM workshops with all the design authors.

• Get early sub‐contractor buy‐in for the M&E Model.
