BIM: Efficiency Through Collaboration
What is BIM?
Whole Life Costing
Whole Life Costing
Programme & Logistics
Risk Analysis
Use 3D Model to Eliminate Risks
Facilities Management
Fragmented process of passing information, progressing the project, monitoring the project and managing the project.
Delays of information causes increased costs and higher risks - can cause costly errors, variations / changes at later stages.
BIM brings all relevant parties to table earlier to reduce cost, improve efficiency and effectively manage the project.
View of some basic information required to assess effectiveness of a project.
Without anyone of these - how can the project be effective?
Without BIM/collaborative working gaining the best for the client is a much bigger challenge.
Location of pumping chamber.
Access and maintenance of pumping chamber.
Cost / benefit analysis and importance of whole life cycle analysis.
The 3D Model allows for realising possible threats through visualisation.
Building two models - Physical and Virtual
Risks Include:
Profit is about managing risk
BIM – Process for managing risk/ contingency.
Aim – to prevent delay;
Identifying Problems
Create preventative measures
Allow for detailed impact assessment - Financial and Durational
Asset Information Model (AIM)
BIM provides the construction industry with a collaborative method of collecting and using information across a construction project. It aims to provide a seamless link between the designers, the client, construction professionals, contractor and end user of a project from the project inception through to the final decommissioning of the project after its intended life has expired.
Risk Analysis
Risk commonly dealt with 10% contingency – inefficient
How BIM Manages Risks ?
Managing risk through clash detection
Hitting Target Dates.
Improving the Bottom Line
An Example; Crossrails Use of BIM

Farringdon Station
3D model linked to the delivery programme cost £120k but saved over £8million from risk contingency
Visualise build sequencing.
Strategise material and labour distribution.
Highlight high risk work areas at various times during the construction.
Efficiently manage logistics throughout the construction.
Clearer progress checks against the contract programme.
Litigation
And perhaps even bankruptcy
Example - The Channel Tunnel
The Channel Tunnel Construction started in 1988.

The project took approximately 20% longer than planned (at 6 years vs. 5 years) and came in 80% over budget (at £4.6 billion pounds vs. £2.6 billion pound forecast).

Three main factors delayed the project;

Changed specifications for the tunnel, there was need for air conditioning systems to improve safety that were not included the initial design
The communication between the British and French teams who were essentially tunnelling from the two different side was poor. It was said that junior employees were often more informed about project status than senior managers.
The contract was bid on by competing firms, which led to a low and optimistic price estimate from contractors.

All these problems could have been overcome through the use of BIM!!!!

Why Should You Use BIM?
Allows for more to be done off site – e.g. planned structures, lean construction
Onsite clashes of workforce are eliminated
Easier to solve on the model that it is on-site
Ultimate aim to eliminate possible delays and save you money.
