Project Overview



Government Construction Strategy May 2011


Red Letter Days:

Construction 2025July 2013



Phone call from Ministry of Justice 9 November 2011

Q: “You know the project you have designed in 2D, it’s now a BIM project and this

Red Letter Days:

now a BIM project and this fact must not affect the programme. Can you do this?”

A: “Why of course we can....”


Why Cookham Wood andwhat made the team soenthusiastic to take part?

• MoJ’s eagerness to adopt BIM and the timing – 6 months after the Government Construction Strategy was released

• A willing supply chain who saw the advantage of taking part in an early adopter BIM project


• Assurances all round that the adoption of BIM would not affect the programme

• Project type

• Project scale


• MOST IMPORTANTLY – an engaged, intelligent and equally enthusiastic client

BIM: Practical Lessons LearntThe Challenges

1. Defining the Clients BIM Requirements and communicating these to the MoJ’s Constructors Framework

2. The lack of BIM Standards and Best Practice (BIM Task Group formed at the time that the Cookham Wood project started)

3. A large spread of BIM understanding and BIM maturity


The Advantages

1. PPC2000 partnering contract ethos leant itself to the adoption if BIM as a collaborative tool

2. The MoJ’s Lean Delivery Management could benefit from the use of BIM – for example modelling, programming and design efficiency

Better / earlier design certainty and collaboration,

resulting in efficiency savings and waste reduction

3 MoJ Requirements: Summary

1. Better / earlier design certainty and collaboration

2. Informing a BIM technical library, deriving demonstrable lessons learnt and ensuring that over time increased built asset as a percentage of spend (eliminating unnecessary re-design on each new project)


3. Having the right data to take through the life of a project and efficient transfer of data to CAFM systems

With these objectives in mind we were able to make sure we kept focused and delivered the MoJ’s requirements

This was in effect the first draft Employers Information Requirements document (EIR)

BIM: Practical Lessons LearntGoing Out to Tender

First draft ‘Employers Information Requirements’ document EIR, issued to the Constructors at ITT


Eventually the production of the MoJ’s EIR was aided by the development of:

‘Plain Language Questions’


Tender ResponsesFirst Draft BIM Execution Plan (BEP)

Ensuring not only the Common Data Environment, software, collaboration processes etc were described, but importantly also describing how MoJ’s requirements were to be met (Arup produced this for Interserve)

Example: Examining Planet (CAFM) data requirements and ensuring that the Handover (Stage 6) COBie data drop contained this information as a minimum

Immediate Advantages of BIM:

BIM: Practical Lessons LearntImmediate Advantages of BIM:

Mike Potten, Head of Works

“In my new role being appointed as temporary Head of Works and new to the establishment, I was invited to a soft landings meeting... the BIM model was displayed on a projector and I was walked through the model. [This] helped no end in getting up to speed with the


[This] helped no end in getting up to speed with the project. I was able to look at access and maintenance arrangements in plant rooms... making sure that what was being offered met the needs and practicability of the in-house maintenance teams and service contracts that they would have to put in place...”


LIDAR survey used as validation



Health & Safety and Site Induction



Defining Access for Maintenance



Other Advantages

• Empowering real collaboration, resulting in:- Early full design coordination (inc MEP spatial design)

- Design confidence- Getting things right first time


• Providing one source of all design information, including data, for each design discipline

• Helping to streamline construction and reduce the programme

• End user induction for efficient commissioning, handover and occupation


Continuous Learning


Cookham Wood: Some of my personal lessons learnt

• Be pragmatic – don’t let the best be the enemy of the good

• Put BIM at the centre of what you do, you’ll be surprised just how many benefits it drives

• A well written comprehensive BEP is key (and a well written, comprehensive EIR is a essential starting point)

• Regular comprehensive model federation / design coordination


• Regular comprehensive model federation / design coordination

• MEP: early spatial not schematic design

• As early as possible agree a method for clash detection, reporting and scheduling

• Keep model up to date at all times (early stakeholder engagement / sign off helps)

• Keep data up to date at all times (supply chain involvement in BIM helps)

Cookham Wood: Some of my personal lessons learnt

• COBie Data / Data Management – employ expertise or select / comprehensively train existing staff

• Be proactive: with lessons learn workshops ongoing throughout projects

MoJ BIM ProjectsExemplary practice and also many challenges

To date projects have had early(ish) adopter status:

• all have had some issues, but there have been immediate tangible benefits

• there has been an impressive uptake of BIM


• there has been an impressive uptake of BIM

• and continuous improvement (HMP Winchester project early COBie Drop 6, prior to the end of Stage 6)

MoJ is very close to delivering the Government’s objective of achieving Level 2 BIM on all its projectswell in advance of 2016
