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


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


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 ?

• Long-standing relationship in Scotland• History of collaboration on R&D• Similar strategy of volume building• Potential for standardisation, repetition• Their willingness to truly partner

Over 770 Plots of timber frame delivered and erected in past 12 months

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

Associate

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?


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


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


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



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


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


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


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


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

acoustically as a traditional metal stud wall.

Increased challenges for our acoustician.


LIVERPOOL PRIMARY SCHOOLS

− 2 no. new build schools both 2 storey 2

form entry, to be built adjacent to the

existing schools which will be demolished

− 2,715sqm GIFA

− £5.5M each delivered as part of the

Liverpool Schools Investment Programme

− Both schools bought into the concept and

joint client engagement reviews were held

− These highly successful sessions allowed

each school to particularise the design to

suit their educational vision

Prototype GA



− 2 no. new build schools both 2 storey 2

form entry, to be built adjacent to the

existing schools which will be demolished

− 2,715sqm GIFA

− £5.5M each delivered as part of the

Liverpool Schools Investment Programme

− Both schools bought into the concept and

joint client engagement reviews were held

− These highly successful sessions allowed

each school to particularise the design to

suit their educational vision

New Park GA



− 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



− Highly Commended ‘Architect of the Year’

Structural Timber Awards

− Morgan Sindall achieved ‘Contractor of the

Year’ at the same event


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.

Other areas include:

What is BIM?A geometric visualization of the components of an asset


A process for collaboratively creating, operating & disposing of the asset



The ability to access asset information across the Whole Life Cycle

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

Social Housing with BIM

Allows for full integration of designEnables clash check detectionOptimises room layoutFocuses the client on what is importantSpeeds up constructionCan integrate into facilities management

process’sSaves money & time

Advantages


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


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
