Today’s presentation

• BIM Background

• Introduction of UK BIM Alliance

• Case Studies drawn from BIM4Housing members, • Legal,

• Design,

• Development,

• Supply Chain,

• HM Government,

• Role of BIM4Housing & its Future Work

BIM Background • March 2016: HMG Construction Strategy 2025

updated

• April 2016 BIM mandate for centrally procured Projects

• September 2016 BIM Task Group becomes Digital Built Britain (DBB)

• 25th October 2016 BTG role transferred to UKBIM Alliance

• DBB work to implement Level 3 BIM

Government Construction Strategy

• Better Client Briefs and reduced scope • More supply chain engagement • More price benchmarking • More offsite manufacture and

prefabrication • Better visibility of forward program • Replace adversarial with collaborative

cultures • Better alignment of design, construct,

occupy and manage

BIM forms part of the whole strategy.

Other areas include:

HM Government 2013 Industrial Strategy: government and industry in partnership

Towards a Digital Built Britain.

BIM is about digital information

The right information

In the right place

At the right time

In the right format

To the right level of detail

With the right assured processes

To make the right decisions

For significantly improved

What does this mean for the

housing sector? •Early collaborative stakeholder engagement •Early design visualisation & optioneering •80% modular kit of parts, 20% bespoke •Option variation through configuration •Reduced initiation to handover •Reduced risk premium •Improved operational performance •Improved whole-life value

Case Study 1 With thanks to

Richard Whittaker, Nottingham City Homes

Building a Better Nottingham

Meadows and Cranwell Design

Meadows Q blocks currently out to tender in

conjunction with Cranwell Road and consists of:

8 x 2 b semi-detached bungalows

1 x 2b detached bungalow

16 x 2b terraced houses

24 x 2b semi-detached houses

1 x 2b detached house

4 x 3b semidetached houses

National BIM pilot

Cranwell Road consists of:

12 x 1 bedroom flats plus study

10 x 2 b terraced bungalows

1 x 1b detached bungalow

14 x 2b semi-detached houses

10 x 2b with study semi-detached houses

1 x 2b detached house

Building a Better Nottingham

Two sites – One constructor partner Meadows – BIM – Modern Methods of Construction

Cranwell – Traditional construction methods

Construction Project Information Exchange (CPIX)

All documents for exchange of information are prepared using the

rules of CPIX

Project Implementation Plan (PIP)

This is submitted pre-contract-award to convey each potential

supplier’s capability

related to information management.

Task Information Delivery Plan (TIDP)

Building a Better Nottingham

Difficulties to Date

A significant amount of effort to set up

Contractor buy in, early engagement

Contractors not using BIM models to price work

Supply chain using BIM to inform the model

Client not managing the change process.

Case Study 2 Meadow Road, Worthing

2013 - 2015 With thanks to

Worthing Homes/Clarkson Alliance

Worthing Homes, ClearBox & The Clarkson Alliance

• Collaboration Partners

• Worthing Homes, PMC Construction

• The Clarkson Alliance, ECE Architecture

• Clearbox BIMxtra (middleware platform)

• Host project - Meadow Rd • The project comprises the re-development of 12 new-build 2

bedroom houses of 77 - 79m2 arranged in three blocks units

• Contract Value £1.39m

• Full Interim Report http://www.worthing-homes.org.uk/media/BIM-Interim-report-Feb-2015.pdf

• See also: http://www.bimplus.co.uk/projects/meadow-road-sheltered-housing-scheme-worthing/

Progress June 2015

(Some of the) Lessons Learnt

• EIRs Specification and Performance Specification, which takes contractual priority?

• Involving the supply chain • Early Contractor and supplier involvement

• 2 stage tendering for D&B contract,

• Early sub-contractor, supplier and manufacturer involvement

• BIM objects - BIM (non)-readiness of supply chain

• It’s not just about the supply of components it’s also the supply of information

Summary of Outcomes:- • BIM has the opportunity to revolutionise our industry

• For any revolution to take place there is a need for us all to change

• Benefits are significant

• Design Costs reduced by 10%,

• Construction Costs reduced by 20%

• Contract Period reduced by 10%

• Defects reduced by 25%

• Post Contract Change reduced by 90%

• Improve quality & reduce waste

• Improving buildability

• Moving Construction to an assembly process

• Achieving targets set for 2025 Construction Strategy

BIM4Housing Forum • Part of BIM4Communities working with BIM4SMEs,

BIM4M2 etc.

• BIM4 Communities will take over the role of BIM Task Group in September 2016

• Purpose • Industry Self-Help

• To advise, encourage, demonstrate how BIM can assist • Developers

• Housing Associations, Local Government/RPs

• Makeup • Loose participation so far, providing feedback & information to

participants, draws on wide industry knowledge (including Norwegian HomeBuilders’ Federation)

• Formal Steering Group established

• Continuing Volunteer basis

BIM4Housing Work In Progress

Preparation of website as Interactive tool for advancement of “Better Practice”

BIM4Housing Forum - Future Work 2016

• Demonstrations to Industry, particularly HAs/RPs, but also smaller Builder Developers

• Provide advice to meet requirements of OJEU Tenders

• Templates for OIRs EIRs BEPs

• Build Housing Live Summer 2017 to • Showcase successful work

• Identify pressure points

• Identify information needed by long-term Housing Asset Owners

• Identify information for Home Performance Labelling

• Identify methods to capture existing Asset information • Existing Housing Stock: 24.5m households !! (Just like CO2 reduction)

• New construction adding up to 200,000 units pa. < to 1% increase

BIM Benefits - whom? • Commercial, Financial, Tenant Liaison?

• Decisions Required: • What Data is needed for better Asset Management?

• How is data used?

• Hand-Over information formats - • H&S/O&M ?

• Hard copy, Digital, pdf?

• Security • Who should have access?

• What Level of Detail?

• All part of Employer’s Information Requirements
