BIM4Housing Construction Working Group Meeting

George: how do we compare one product with another product? Testing regimes are different for each standard. And what is each product tested against?[Tom Cannon, hill construction, left working group, so George is leading this session]
BIM4HOUSING six working groups. Development, design, construction, manufacturing, advisory, operations. Construction working group not all constructors but various relevant specialties to combine knowledge.
Idea of individual groups is to focus on a particular topic and then they can relate across the board. Each group meets once a quarter.
WORKSTREAMS work intensively, take instructions from working groups and do things eg on SUSTAINABILITY or ACCESSIBILITY, then workstream is closed.
WORKSTREAMS: Data, MMC, Fire Safety.
DATA STANDARDISATION WORKSTREAM WORKED WITH MIM4HA, BRE and others, machine readable data critical (we cannot rely on people only) we make sense of different standards by working with BRE who have a free resource called Templater so we can gather together all the information /attributes and provide it to product manufacturers who can then describe their products in a standardized way.
SUSTAINABILITY WORKSTREAM GROUP report being produced by Cambridge University academic (phD). Purpose: to understand what community was doing in terms of sustainability – using a questionnaire presenting roles, type of project, what relative importance of sustainability in your work etc. Then fed back to Cambridge University to create final report.
Will merge this with new group: ZEROCONSTRUCT. Purpose: members of wider BIM community will also contribute.
MMC GROUP engaged with design working group to look at various aspects from an MMC perspective to be delivered through better practice. (38 mins)
Also Supply Chain Sustainability offers free training material.
Liability on Developers and Contractors increasing to 30 years. Responsibilities for defective premises act seem to be changing, we are trying to tackle this.
BUILDING SAFETY BILL we need to be looking at structured digital data, we need to have in machine readable way so non-COBie attributes can be tested.
FIRE SAFETY WORKING GROUP questionnaire with all information re data to inform a safety case. Working with 360’ photos and Specifications. Purpose: What information will be needed to clear gateway 2 then gateway 3?
Change management – are products that are being supplied are actually satisfying the performance requirements. Therefore, when something does get changed it will be picked up, so that procurement goes smoothly: what gets ordered is what gets delivered. So there is a correct record of what is installed. All registered by experts in each field.
Purpose: all stakeholders can see the same data but see only info that is relevant to them.
MASTER RISK LIBRARY, a standardized data catalogue- it is part of the fire safety group. One can go into each asset and can create more managed data. (End of George ~46:23)
Term (data scientists): ONTOLOGY something being used in a different context. E.g. if you have one type of product has to be used differently in different environment.
WHAT ACTIVITIES FROM THIS GROUP ARE IMPORTANT?
Martin: Golden Thread Tier 1 IQ group have done 3 meetings sharing experience/ understanding/ knowledge, now about to split into 3 workstreams, will now drill into exercises/tasks.
Mark: conversations about data and understanding it. Link between earlier stages and the gateways. How many people have validated stage 4 before moving on construction stage 5? In Dec 2023 we’re gonna have to be working with gateway 2 and gateway 3.
George: it’s important to have sustainability/accessibility information at, for example, work stage 3 even though you will not have the serial number until work stage 6. The Templater enables you to do this, to know which actor should do what action at which time.
Mike: important that constructors get the info they need to actually build the buildings. How much data is really useful and how much data gets in the way?
Asif: going round and round in circles with pre-construction element. (1:02)
Martin: we have a responsibility towards clients, who are not responsible for knowing – we are- the experts.
All data needs to be machine-readable. Danger: the fragmented data problem. A following-through process from start to finish. That s the purpose of BIM4Housing
Responsibility Matrix: knowing who is responsible for what data. A common way to access risk.
All the data standards are made by private companies, competing entities. How do we unify these? There are 800 standards in building regulations. George wants to identify what are the 3 things we need to know about for e.g. a fire door if we want to buy it/inspect it /install it etc. How can we take this complex set of knowledge and make it consumable?
TEMPLATER: BRE have made videos re what it's about. If you have a smoke detector it appears in different Uniclass tables but you have to know where to choose from. So based on what you want to do e.g. maintenance you go to the relevant one.
