The document discusses the challenges of improving productivity in construction through BIM (Building Information Modeling), highlighting that 30-40% of costs are due to rework. Several reasons for the lack of productivity gains are identified, including unclear information requirements from clients, disconnects in contract structures, and non-adherence to standards. The document emphasizes the necessity for better information management, automation, and standardized workflows to realize potential productivity improvements of up to 20%.

2. The need for change - PRODUCTIVITY
24 May 2018 2
30-40% of construction
costs are down to rework
Can we deliver more with
less – Automation –
Standardised Delivery

3. How are we going to achieve this?
Its all about Better Information Management
Standardising our best workflows with
technology providing automation.

6. The 2018 NBS report
58% of respondent thought that the UK BIM mandate has not been
successful

7. So BIM is the answer, but what has gone wrong?
Since the 2011 construction strategy and
BIM mandate productivity in UK up approx.
1%. Globally 1% over 20 years.
CEOs were expecting a big increase,
why hasn’t this happened? They are
losing/lost patience

8. So why hasn’t BIM improved productivity?
Theory: Better Information
Management = productivity
increases.
Why hasn’t this happened?

9. So why hasn’t BIM improved productivity?
1 – Info Requirements
Clients still not clear what information they want,
most EIRs are made by consultants, copy and
paste.
Action – Clients need to take control of what info
they require and how they will use it.

10. So why hasn’t BIM improved productivity?
2 – Contracts
Designer employed by client on time and
material and the contractor is also
employed by the client, there is A- Total
disconnect between supply chain (Silos). B-
No incentive to make savings
Action – Contracts for Value, Project 13

11. So why hasn’t BIM improved productivity?
3 – Standards
Not everyone adheres to them, e.g. IAN
184 allows free text field for a product
description with Uniclass. Result
everyone had their own names,
federating a model takes a life time
Action – Follow standards

12. So why hasn’t BIM improved productivity?
4 – Standards
Blindly trying to implement BIM L2 standards without
thinking about value adding
Action – Make sure whole supply chain develop BEP,
it has clear requirements, processes, it is agreed with
the client, used by the project team and benefits
monitored.

13. Making BIM useful for PMs
Allow the PMs to get benefit of BIM
Track project requirements,
functional, cost, programme etc
against the deliverables set in the
MIDP, and published in the CDE.

5 – Pic and Mix modelling.
Supply chain working in 2D and 3D, CDE and IDC not properly managed,
engineers still working in 2D = disaster
Action – All supply chain to agree on LOD, deliverables, CDE process, and IDC
period and process, and most importantly train their staff, then enforce and
measure

17. What about Automation and DfMA?
Need the basics of Information Management right first.
