Overview 1. The Context of BIM 2. Getting into BIM 3. BIM & Passivhaus

1. The Context of BIM

BIM isn’t new!

Why now? 1. Software & Hardware capabilities 3d Modeling Structured Information Digital Collaboration

Why now? 2. Digital / Social Media ‘Tsunami’ Digital everything Social everything … will the construction industry catch up?

Why UK Gov + BIM?

EU Directive Energy Performance of Buildings Buildings consume 40% of energy in EU By 2018 All new public buildings “Nearly Zero-Energy” By 2020 All new buildings “Nearly Zero-Energy”

UK Gov Strategy

Mandated BIM

What is UK Gov BIM? “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Office 2012

UK Gov Purpose 20% reduction in capital costs 20% reduction in CO2 emissions + reliable outcomes + predictable building (asset) performance

UK Gov BIM + GSL

BIM standards

BIM Protocols

2. Getting into BIM

Observing Pre-BIM Duplicate working Designing in 3d, documenting in 2d CAD standards not always enforced

Proposing BIM Quick “proving exercise” Demonstration of key benefits Overcoming doubts & resistance to change

BIM Pilot Project Rules Small / Medium single storey Short duration Bland, not too creative Plan for pulling back to CAD

BIM Pilot Project Rules

Benefits Carefully manages risk, minimises potential losses Facilitate a gradual transition / learning Allows for easy comparison between projects

Risks No benefits of BIM gained No memorable experiences No mindset-shift

Following the Rules: “BIM is a RISK to be managed”

OR… No Rules? Large project, multi-storey Long duration Highly creative, challenging design Commit to BIM, no plan to pull back to CAD

Start! With a project that matters to your business

Benefits Maximises all available benefits of BIM Longer duration allows for learning & mistakes Exciting, interesting, engaging… the BIM mindset sticks

Risks Much more at stake that could go wrong High level of training & support needed Takes longer to see the results, harder to compare

No Rules “BIM is an OPPORTUNITY to be realised”

Our Pilot Project

The Willows £17m / 6500sqm Lifelong learning campus Multiple clients Complex geometry 6 Phases, 10 Mineshafts

Ensuring Success Training / Support Project based bespoke training At desk training In-house expert (guess who?!)

Ensure Success The Team Tasks to suit abilities (not roles) Focus on LOD for outputs & outcomes Involve whole team in the real-world project

Results Stage D output in 4 weeks, reduced Stage E-F team 500+ drawing sheets,1355 unique views directly from the digital model Massive productivity gain Site RFI turn around in hours (not days!)

Bonus Results Unexpected use of the model Staff exceeding expectations Spread of BIM skills

5 Stages of BIM 1.  Initial Excitement “Wow, Look what I can do with this thing!”

5 Stages of BIM 2.  First Bump “Why won’t it do what I want? …It was easy in CAD!”

5 Stages of BIM 3.  Creamy Middle “Things are going smoothly now”

5 Stages of BIM 4.  WTF!? “Component Creation eats you up and spits you out”

5 Stages of BIM 5.  Enlightenment “Things really click. You understand why things happen in the model, how to control them and how to avoid problems”

State of Mind vs Skill

State of Mind vs Skill

State of Mind vs Skill

Beyond the first project Internal uptake External demand The wider design team / Level 2 BIM

Bidding

LOD

Designing

Communicating

Almost Level 2

3. BIM & Passivhaus

Passivhaus Standard “…the world’s leading standard in energy efficient design” Rigorous performance standard Quality assurance Optimal comfort (ISO 7730) Minimal energy Climate specific – works anywhere

PHPP: BIM or BEM? “simplified models, precise data” Accurate Open Parametric Instant

Data 4 QA Passivhaus can be seen as a quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable robust energy performance & comfort.

BIM + Passivhaus Process + Information + Model and test Not box ticking Not sexy graphics Not on site

BIM 4 Passivhaus Simple + Useful + Productive 1.  Visual interrogation 2.  Accurate Live Numerical Data

Visual Interrogation Design coordination / integration Thermal Continuity Heat Loss Envelope

Design Coordination

Design Coordination

Thermal Continuity

Thermal Bridges

Heat Loss Envelope

Accurate Live Data Treated Floor Area (TFA) Actual Volumes Ventilation Volumes Heat Loss Areas Window / Door Opening Areas

Areas and Volumes

Heat Loss Areas

Opening Areas

What does this deliver? 2 x 65kW Boilers for a 2200m2 School 25kW peak heat demand = 5x oversized! 90% reduction in gas consumption

Breathe easy!

“We feel that our children are more alert and attentive in lessons due to the amount of daylight in classrooms and the fresh air throughout the school ... learning has been enhanced” Sara Morris, Head Teacher Client Satisfaction
