BIM for Spekkies?

•  BIM is on the horizon for most •  Some claim it, few do it, even fewer do it well •  One already talks convincingly about Beyond

BIM •  Like all new technology we start with chaos, as

we experiment, find dead end and finally steer a course to a good destination.

•  We are reliant upon others to provide the tools to exploit the full potential

•  So here is a whizz round a spec writers mind –  what do I want from BIM?

•  More importantly how can BIM help in the ‘Sustainability Revolution’? –  Resource efficiency/effectiveness in particular

Holy Trinity

•  Drawings show the assembly –  Shape, size, arrangement

•  Specifications describe the materials –  ‘Specification’ not a ‘Generalisation’

•  Bills of Quantities quantify the materials –  shopping list of quantities –  DWISOTC “Does what is says on….”

•  Each has a role –  None should undermine the other

•  Say it once in the specification –  Cross reference from the others

•  The demise of the Holy Trinity is nigh? •  Long live BIM? Inevitably



CAD

•  Computer aided design/drawing? •  computerized drawing board •  The barrier that stopped BIM from

developing for a few decades •  2D

– Lines in section or plan – Line length – Line weights – Line colours – Preset Line styles? (templates)

•  Create once and reuse

CI/SfB (Template Classification)

•  Library classification –  E.g. (24) Stairs Ramps

•  Drawing numbering –  AAA 1234 Z2 (24) 001

•  CAD Layers –  24_stairs_ramps_balustrades

•  Packages? –  3024 Stairs –  Procurement methods

•  RIP: CI/SfB? •  It was hard enough to learn CI/SfB

–  don’t expect us to learn something new! •  Long live: Elemental Uniclass?

Procurement methods

•  GC General Contracting –  M&W Prescriptive Specifications

•  D&B Design & Build (help reduce costs) –  B&D Build & Design (redraw in reality) –  Employer’s Requirements (EIR Information in BIM)

•  Performance Specifications (A90) •  CM Construction Management (speed up build)

–  Packages (trade or zone or phase) •  MC Management Contracting (speed up build) •  DMC Design Manage Construct (1 stop shop) •  PFI/PPP (Government Procurement route)

–  +FM Facilities management (Bankrupt the NHS) •  BOOT

–  Build Own Operate Transfer •  DBFO, DRFO,

–  Design, Build/Refurb Finance, Operate

OLE

•  Object Linking and Embedding •  XRef (to a piece you prepared earlier)

–  e.g. elemental section (template potential) •  Blocks •  Symbols (Templates)

–  Libraries and instances –  Annotation: say it once and link instances to it –  Correct a symbol once

•  all instances update instantly

•  Paper space (Template) –  A place to put things (assemble many Xrefs) –  Collections of related sections of assemblies

XYZ

•  3D: 3 Dimensional –  Lines in space, start/end point, direction, angle, length

•  Objects (Templates) –  not just lines in space –  joined up and knows it ‘awareness of self?’ –  Components + Accessories = Systems

•  Components > Sub-systems > Elements > Buildings •  Assembly, fixings, fasteners, edges, abutments, joints,

•  Size –  Geometry of part(s) –  Sub-components, permutations of sizes –  Multiple modules of components

•  Properties (Parameters) •  Awareness of appropriate sizes to avoid waste? •  Awareness of placement of openings to avoid cutting waste?

•  Solid and void –  Physical properties?

AI Artificial Intelligence

•  RUCAPS (>30 years ago) –  Clash detection, Panelled construction, –  M&E/Structure, never occupying same space

•  Bridge (>20 years ago) –  3D Relationships (Building to site, room to circulation)

•  Bubble diagrams which evolve into CAD model •  From Site to Building to Objects to fasteners

–  Objects (with information attached) Templates •  e.g. furniture/appliances •  Sticky-back fits to wall •  Sticky-bottom sits on floor

–  Connections: Services need connection points –  Passages: Holes for Services through objects –  Objects with passage holes: for services

•  Snap (not snap to grid) –  Don’t stretch objects or they snap –  Stuff has a size, work with it, not against it.

Standard Details (Templates)

•  Never, I am an artiste –  Never the same thing twice (BS plaster thickness and beads)

•  But they were/are popular –  GLC details –  PSA Spec MOB Method of Building –  Landscape Detailing books –  AJ Everyday details –  Detail magazine –  AJ Working details

•  Well that’s okay he’s famous, my peers will bow to me too •  copyright infringement is okay isn’t it?

–  Follow manufacturers recommendation or no guarantee •  TRADA still gets a call everyday from Architects getting

H21 weatherboarding wrong •  Standard competent approaches

–  Competent, safe, tried and tested solutions –  With standard specification clauses –  Feel free to change the profile on every job



AEC (Templates)

•  Architecture Engineering Construction •  Libraries of objects (Templates)

–  (Sizes and arrangement) –  RIBA CAD: do they still exist? –  Fasttrack: did they join forces?

•  Properties: potentially data attached •  We can now know the size of stuff

–  And design accordingly •  But mostly we do not

–  Bricks are easy but not everybody does •  Blocks are multiples of bricks

–  Plasterboard of know size •  off cuts 30% wasted BRE/CRWP



BBMs

•  Bio-based Building Materials •  Properties:

–  of conventional materials known and not questioned –  Strength, Workability, Durability, Appearance, k value,

•  Properties: of BBMs claimed, not understood –  DD Decrement Delay, H Hygroscopicity,

MM Moisture Mass, MP Moisture Permeability, •  Environmental Criteria

–  EE Embodied Energy, EC Embodied Carbon, SC Sequestered Carbon, EW Embodied Water

•  Big Open Data: in its infancy, •  Building Physics/Science v art, poetry & BS

–  not understood and not trusted yet –  Usually complex needs a specialist

FSC PC/FC & CofC

•  Origin Provenance (UK is ideal) –  Plantation Certification (choose if possible) –  Forest Certification (avoid forest if possible) –  Need some novel applications for Ash, quickly

•  Chain of custody (CofC) –  To UK yards and better still to sites

•  EUTR Legal sourcing by 2013 –  NEPCon Sourcing hub GBE G#16016

•  Transportation data –  Satellite GPS Logging and tracking?

•  BIM product data collection? –  Put to use later (See BREEAM)

Waste v Resources

•  Cost of resources, materials, products •  Cost of use •  Burden of waste, 109m tonnes/annum

–  33% is offcuts by loose cannons (designers) •  Shrinking landfill capacity

–  Landfill Gate Costs •  Landfill tax escalator

–  Rising costs –  Cost of different waste types

•  Cost of treatment before landfill –  Cost of segregation of waste or processing waste

•  Value of diverted resources •  Aggregates Levy encourages recycling

–  Provenance of recyclate (data collection & flow)

SWMP (Templates)

•  Site Waste Management Plans –  Workshops & Checklists (spreadsheets) –  Workshop Templates GBE G#551

•  Timber is biodegradable: Active waste? •  Treatment is hazardous:

–  Hazardous waste? –  but timber is now inactive?

•  Treated timber: hazardous or mixed? •  Provenance: (evidence of source and

spec) for resale and reuse or recycling –  Bar coding opportunity?

•  Material exchange websites



Waste Statistics

•  BRE own most of it – SMART Waste and SMART Audit

•  BRE collect it at your expense – Charge us to see it – But BRE can’t always audit trail to source of

data – BRE Fudge the data so excavation waste

does not skew the data/statistics •  If we all capture the data

– we need to make it publicly available –  to share and learn the truth

•  Not BRE’s version of the truth



RE/E

•  Resource Efficiency/Effectiveness •  Scale of problem, responsibility, blame

assignment •  awareness of size, assembly patterns and

rhythm •  Starting, stopping and positioning openings •  Ignore > interruption of rhythm, cutting waste, •  Cut & Fill: +ve & -ve •  Civil engineering: no import/export no waste •  Construction: Skip loads to landfill



DfRE

•  Design for Resource Efficiency •  33% of 109m tonnes/annum is off-cuts •  Because we do not know the size of

stuff •  Text books and standards

– Remain unread – Or ignored because its inconvenient – 500, 600, 150 mm few common factors



CAM

•  CAD CAM •  Computer Aided Manufacturing •  Not sizes and shapes

– collections of points in space •  Iteration:

– Tailoring, Patterns, resource optimization –  Ignoring SMM rules – Some greenwash: GLA building London



QRE

•  NEDO survey of construction industry 1987 report

•  Quality Related Events –  Any event that could effect the quality of the

end result •  Information: late, errors, conflicting •  Blame assigned:

–  50% design and specification –  50% materials and installation

•  Cause? –  2 different classifications –  SMM6 & CI/SfB –  CI/SfB is dead, long live CAWS, CI/SfB or

Uniclass



MS Office (Templates)

•  Projects: Record QRE – Wish lists (wish we could do this bettter) – Feedback loops (learn from mistakes)

•  Templates (Capture learning for next) – Reinforce learning (into every job) – Corporate Knowledge Management

•  Styles – Set once reapply in many instances

•  Paintbrush – Apply styles



SMM6 v CI/SfB

•  SMM6 12 divisions •  CI/SfB unlimited permutations •  Cross referencing impossibilities •  Conflict potential •  Gaps: between which to fall

SMM7 & CAWS 1987

•  Common Arrangement of Work Sections •  Common classification between Architects and

QS –  Some Specifications did not adopt and disappeared

•  By Trades and a few Elements –  Cross reference to supporting work sections: Prelims

A; P and Z sections –  Messy & Complex for Specifiers –  Especially for procurement methods –  Cross referencing and coordination –  Errors or omissions creep in –  Or DLSS cut down more trees to make more paper for

thicker specifications with endless repetition



A3u (Templates)

•  Specification – Physical Properties – Performance characteristics – Environmental characteristics – Certification, Accreditation, Endorsements,

Accolades •  Architects hate writing specification

– Errors creep in •  Ready-made product specifications to

adopt and edit if required (Templates)

GBE Robust Specification

•  Extended CAWS work section & clause numbering (therefore NBS compatible)

•  Robust against substitution unlike NBS – Product Specific clause content – The reason you specified it in the first place

•  is included in the clause •  For equivalency comparison

– Performance: described in detail – Accreditations: listed – All information for all men

•  Whoever reads it gets what they need to know



GBE BEST

•  Building Element Sustainability Test – Functional Components

•  All of them – Performance

•  Competency of assembly to meets requirements •  No degradation or diminishing over time

– Correct order in section •  To carryout task and prevent failures

– Compatibility of materials •  No reactions between each other •  No reactions over time



GBE PASS

•  Product Accessory System Screening •  400 criteria for success (so far) •  Not all apply to every application •  Traffic Light system •  Green is okay, Red is not, Violate is bad •  Screening against criteria

– Could and should have a project focus •  Spreadsheets contain the data



IAQ

•  Indoor Air Quality •  As buildings get more airtight

–  IAQ becomes very important – For H&W Health & Wellbeing

•  GGtS Expressly excludes: –  IAQ – Toxicity

•  So we can build unhealthy – and call it Green “BRE Green”



BIM

•  Building INFORMATION Modelling –  Better Information Management

•  Big Data: –  Everything everybody ever wants to know

•  Open Data: –  Everyone can contribute –  Accessible without fee –  Able to be selective when viewing (LOI)

•  A place of all the data –  Adopting right classification system(s) –  Digital Object Identification (DOI)

•  Reliable data –  Verified by independent 3rd parties (tests/certs) –  Data in all the right places

Excel spreadsheets

•  Prevents development of BIM! –  (Paul Fletcher Beyond BIM)

•  Collecting data –  Mammoth task

•  Maintaining data –  No budget?

•  Updating data –  No budget?

•  Everybody could add to this data –  A piece at a time –  At every stage of the process

•  Dynamic data collection (Open Source) –  Searches when you want it –  Like internet search engines –  Live links to live data sources (many) –  Every cell of spreadsheet: a search function –  Digital Object Identification (DOI) keeps track of data



APPs

•  Computer Applications •  Once the BInformationM exists •  There is too much to be helpful •  We need the APPS to read and interpret

or manipulate the BInformationM •  To become Design & Decision Tools •  To help us to use the answers wisely •  Without the APPS the BInformationM is

almost useless



Open Object

•  Scan shelf content –  not the shelf edge data

•  Scan logos, company and brand names –  Scan in 3D, reconfigure to 2D, –  Recognize them

•  Search the internet –  Bring back CSR and Environmental data –  All in 1 second –  Heading for milliseconds

•  Customers make choices –  Customers take control of retail policy

•  Shared auditable data layer linking siloes of data •  Confirm origin, continuity authenticity, human

rights at source, organic, etc. •  Comparing open and accountable information

about companies and goods •  Brand trust can be restored whilst we are in a crisis

of brand trust.
