Offsite Construction Now & Where it Needs to Be
Richard Ogden, Buildoffsite
www.buildoffsite.com
2016 reminds me of 1989…
Why?• Canary Wharf & Channel Tunnel
• £1400 p/w tunnel face workers
• £1000 p/w steel workers
• Superheated economy
Recognise this?It’s happening again today• Price increase 6% in flat economy
• Clients nervous of cost increases
www.buildoffsite.com
UK Construction Stats• Circa 3 million employed
• Approx. £120 billion per annum (50/50)
• 7% of GDP
• London 2nd most expensive city in the world to build in (see table)
• UK 22nd in global productivity league
www.buildoffsite.com
Waste• Labour only 50% efficient
(skills)
• Waste in materials & design 30%
Safety• 48 deaths on construction sites 2013/14
• Over 50% of deaths due to scaffolding on housing sites
• Why do we still use scaffolding?

Barratt Vision and Drivers
Why Barratt choose Timber Frame?
Tried and tested – Established technology in wider industry, rarely used by Barratt in England since the 1980s.
Some understanding in the business already, step change in delivery and culture but some buy in already.
NHBC Building Control are familiar
Reduces many issues with the weather
Suitable for various building types, up to and including 7 storey apartments.
What is Timber Frame?
• Various options
• Open structural wall panels• Floor and roof cassettes• Pre-insulated panels• Closed Panels (Sigma 2 build system)• Pre-fitted window and door options
The Barratt Timber Frame Specification
• Current• Open /pre-insulated 140mm stud walls• I beam floor and roof cassettes • Trussed roofs build on the wall head• Crane erect process with safety decking
• Future• Pre-insulated walls• Roofs built on slab and lifted up• Scaffold-less erect system• Pre-fitted windows and doors
Why Stewart Milne?
• Long standing relationship with Stewart Milne in North Scotland
• Worked closely together on AimC4 project
• 2014 – Front runner following in depth review (6 month) and tender reconciliation process with 6 national timber frame suppliers
• Looking for a strategic partner to develop more advanced solutions with, not just the traditional manufacturer, client relationship
• Capacity
• Group Agreement finalised November 14 for solussupply to Barratt in England
Why Barratt ?

Projected to be over 8% of the Group’s build (1100+ units) in the current FY
Timber Frame Volumes
Benefits and overcoming challenges - Barratt
• Faster build – particularly apartments
• Weathertight quicker
• Easier to upgrade thermally if regs. change
• Less reliance on brick layers – who are becoming harder to find.
• Standardisation - Volume of Standard Housetype Designs
• Increasing Volume - Culture in some areas of the country
• Reducing Build Cost - True comparisons
• Site Expertise - Site training to realise time savings
• Reduce Programme - Understand impact on other trades
• Negotiation with Building Control
Challenges to overcome - Stewart Milne
• Greater Manufacturing efficiency• SMAS factory improvement plans• Design for manufacture / assembly
• Reduce design and site costs• Deliver benefits of repeatability• Supply chain integration• S&OP - planning work streams
Conclusions / what next ?
• Deliver benefits for both• Extend the relationship• Increase unit numbers• Reduce costs and increase value• Continue R&D - manufacture, development
process• Extract real benefits on site• Stewart Milne goal to become preferred build
method throughout the UK, as per Scotland
The Future
Largest housebuilder 16K homes pa – require a range of construction technologies to service 27 Operating Divisions
Traditional will still deliver the majority for the foreseeable.
Challenge is to deliver practical deliverable solutions to give our Divisions choice to combat local challenges.
Timber Frame is key to this strategy, and future housetype designs are being optimised for this.

Off-site timber frame construction
New Park & Northway Primary Schools, Liverpool
David Wood

OFFSITE OUTLOOK FEB 2016107 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
CASE STUDY
NEW PARK & NORTHWAY PRIMARY SCHOOLS
− Project drivers
− Design process
− Prototype schemes/ off-site structural
timber
− Liverpool schools
− Lessons learnt/ POE/ What next?
OFFSITE OUTLOOK FEB 2016108 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
PROJECT DRIVERS
− July 2011: Morgan Sindall assembled a
design team to respond to the findings of
the James Review and produce a cost
effective approach, learning from best
practice to ensure that schools could be
constructed quickly and efficiently
− Full design team, including timber frame
suppliers and educationalist
− First principles approach
− Re-examined design decisions on
previous primary schools, particularly
timber frame schools delivered in South
Lanarkshire
− Educational story was the main driver
whilst designing the structural timber
frame to be as efficient as possible
− Use of BIM where possible
OFFSITE OUTLOOK FEB 2016109 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
PROJECT DRIVERS
− Brief was to design a suite of 1, 2 and 3
form entry models with a standardised set
of details and specifications
− Target GIFA was to be in line with the
revised area guidelines issued by the
Education Funding Agency (EFA)
− Designs were to be flexible enough to
allow each school or local authority to
shape the buildings to suit their own
educational brief
OFFSITE OUTLOOK FEB 2016110 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
DESIGN PROCESS
− Site visits took place to many of the South
Lanarkshire schools, this allowed the new
design team to learn from their Scottish
counterparts
− Identified inefficiencies in timber frame
design
DESIGN PROCESS
− Simple organisation relating to education
best practice
− Efficient rules which can be applied to
schools of different sizes
− Repeating tartan grid that can allow for
streamlined construction/ off-site
practicalities
− Good perimeter to floor area ratio
− Repeatable/ standardised elements where
possible
− Quick construction period required
− Fabric first approach
OFFSITE OUTLOOK FEB 2016111 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
OFFSITE OUTLOOK FEB 2016112 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
DESIGN PROCESS
Development of the design DNA:
− Clear and simple school organisation
− Strong delineation between KS1 and KS2
− Define a clear entrance
− Good perimeter to floor area ratio
− Excellent connectivity between inside and
outside
− Maximum use of central hub as heart of
school
OFFSITE OUTLOOK FEB 2016113 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
PROTOTYPES
− Extensions and new builds
− Single and two storey
− Flexibility for clients to adapt/ develop their
own designs
− Variety of cladding options possible
− High quality internal environment not
compromised by reducing capital costs
Other options considered:
− LANTAC approval
− Breeam type approval
− Secure By Design type approval
− Review by Zurich
OFFSITE OUTLOOK FEB 2016114 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
OFF-SITE STRUCTURAL TIMBER FRAME
− Adoption of an efficient structural grid that
optimizes the classroom depth for natural
ventilation and daylighting along with other
educational drivers was key to developing
the timber frame
− Various timber sizes were considered to
maximize the external wall U-values
− Trada advice was sought (external timber
walls kept 150mm above external ground
level). Concrete upstand used on later
schemes
− Optimising eaves height to reduce timber
wastage
− Internal M&E service zone to protect
AVCL
Other considerations:
− Insulation between the studs, external
insulation, air-tightness strategy
− Breathability of the external wall
OFFSITE OUTLOOK FEB 2016115 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
OFF-SITE STRUCTURAL TIMBER FRAME SOLUTION
External walls:
− 220mm wide timber stud sections fully
filled with Glasswool insulation, OBS and
breather membrane externally. AVCL
internally with service zone
− Timber sole plate and head binder with
timber glulam ring beam at FF
First floor:
− Formed from metal web engineered joists
fixed to OSB and delivered as a cassette.
Resilient bars below with sound reduction
panel system above
Internal walls:
− Timber stud walls with resilient bars
Roof:
− Formed from metal web engineered joists
fixed to OSB and delivered as a cassette.
AVCL and insulation over
OFFSITE OUTLOOK FEB 2016116 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
OFF-SITE STRUCTURAL TIMBER FRAME
Benefits of off-site timber frame:
− Increased quality
− Better U-values and air-tightness
− Water tight quicker allowing internal
sealing of AVCL to occur in a dry
environment
− Low embodied energy
− Reduced construction period mitigating
impact on the wider community
− Safer construction techniques, less
personnel on site
However internal partitions formed from
timber stud do not perform as well

LIVERPOOL PRIMARY SCHOOLS
− The external footprint and elevations were
pretty much identical (however one red
and one blue)
− KS1 and nursery facilities located at GF
with KS2 at first floor. The double height
central spaces link both floors
− Other facilities include a stepped
assembly area, immersive space, multi-
purpose hall and open plan ICT/ library
space
− The buildings have been a very cost
effective solution, delivered for less than
the EFA equivalent whilst enjoying 23%
additional floor area
− A local spend of over 90% has been
achieved

OFFSITE OUTLOOK FEB 2016121 NEW PARK & NORTHWAY PRIMARY SCHOOLS, LIVERPOOL
LESSONS LEARNT/ POE/ WHAT NEXT?
− One of the project drivers was that each
project would inform the next in a continual
cycle of development and improvement, to
reduce overall project costs whilst
increasing the quality
− This included formal Post Occupancy
Evaluations as well as lessons learnt and
design team/ supplier reviews.
What next:
− Timber frame: The supplier on the
Liverpool Schools has identified even
further efficiencies, mainly with the design
of the internal stud walls
− Increased energy efficiency of the fabric
and M&E strategy
− Passivhaus? With the right site alignment
and a willing client/ local authority we
believe the Passivhaus standard could be
targetted

SUMMARY
− Lower cost/ sqm
− 23% more floor area for the same budget
− Quick construction period and looking to
reduce further on subsequent schemes
− Happy client

Integrating BIM into Housing
A Review of the Work of the BIM4Housing Forum
Patrick Wilson RIBA
Chairman BIM4 Housing Forum
Today’s presentation
• BIM4Housing Forum set up in December 2013 by Andrew Carpenter on behalf of BIM Task Group,
• Material drawn from 2 years of BIM4Housing Roadshows,
• Legal,
• Design,
• Development,
• Supply Chain,
• HM Government,
• Role of BIM4Housing & its Future Work.
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.

Advantages
West Gorton LANB Houses & Apartments
Manchester
It requires the client, design team & contractor to work in a different way
Lack of skill base means that professional teams are not quite up to speed
IT essential but also needs common format
Comes at a cost, £100,000
Challenges
West Gorton LANB Houses & Apartments
Manchester
Optimise option of room layout has saved West Gorton £160,000
Programme has been reduced by 6 weeks due to clash detection
Run through full design prior to build
The above two points have saved £60,000
Less waste which could save an extra £40,000
Total savings £160,000
