IntroductionWhy Do We Need BIM Classification?We have a problem in the construction industry.In terms of project planning and cost estimation, it is crucial for a classificationsystem to be capable of identifying and accurately describing any modelThat problem lies with the lack of a unified classification system. This isn’t newselement.to anyone and today, with the continued development of Building InformationModeling (BIM), this problem has become more topical than ever.The elements in a BIM model can be described by a number of parameters,such as:Apart from reducing design time and costs, the use of BIM technology issupposed to improve communication between the people involved. And this lack Functionof communication is where the real problem lies. Location MaterialFurthermore, the areas of project planning and cost estimation are still Structureunexplored. The industry simply has no means for these processes. Geometry, etc.Kreo is breaking new ground in this respect.These parameters are used by Kreo to define the construction method,sequence, and cost.So, the desired classification system should allow Kreo to organise BIMelements in several different ways at once. Clearly, we need to assign an activityto each element to compose a work breakdown structure (WBS), which isfollowed by Gantt chart generation.On the other hand, we have to group elements differently for cost estimates andit goes without saying that there should be an alignment with an actual costdatabase.The Definitive 2018 Guide to BIMClassification Systems2The Definitive 2018 Guide to BIMClassification Systems3
What Do We Have at Our Disposal Today?It seems a real issue now and, sooner or later, we will have to produce anup-to-date classification system which will fully meet the needs of BIM. Or doesit already exist and perhaps we are missing the elephant in the room?Let’s take a look at the key features of the existing classification rmatCountry ofOrigin / UseUKUSAUKUSAUKUSAYear ofPublication20152006 - 20132012201020122016UpdatesMonthly updatesNo updates---Annualy UpdatesDefinitionPurposeA unifiedclassification systemfor all sectors ofthe UK constructionindustry.The equivalent ofUniclass in the U.S. andCanada.

Element – a majorpart of a group element. A separatecost target can be established for eachelement. Sub-element – a part of anelement. As with elements, a separatecost target can be established for eachsub-element. Component – a measureditem that forms part of an element ora sub-element. The quantity of one ormore items will be measured and thecost estimated to ascertain the costtarget for an element or a sub-element.6Element is amajor component,assembly, orconstructionentity part which,in itself or incombination withother parts, fulfillsa predominatingfunction of theconstruction entity.Designed element isan element for whichthe work result(s)have been defined.The Definitive 2018 Guide to BIMClassification Systems7

Which One Shall We Use?Why Do We Choose UniClass for Kreo?No doubt, UniClass is the most effective classification system available today, iteven claims to be global. Unified approach to classification - simple mapping between classificationtables Regular updates and revisions Flexibility: over 120 thousand meaningful «System» «Product»combinations Claims to be a global classification systemAlthough UniClass and OmniClass have the same framework (ISO 120062:2015), UniClass has several advantages, such as: Unlike OmniClass, UniClass is being constantly revised and updated. Asa result, it remains up-to-date in every sense (up-to-date information,increasing compatibility with BIM, etc.). Redundant and confusing information, such as the Work Results table, isbeing removed. This makes it easier to use with BIM. UniClass tables have similar terminology, sequencing, grouping andcoding.The Definitive 2018 Guide to BIMClassification Systems12The Definitive 2018 Guide to BIMClassification Systems13
How Does It Work in Kreo?Instead of ConclusionsThe New Rules of Measurement (NRM) are used for preparing cost estimatesEver since the idea was thought up, it has become clearer and clearer in theand work schedules in the UK. Together with NRM1 and NRM2, the UniClassindustry that, in practice, BIM is not feasible without a flexible, universallySystem Product combination gives Kreo exhaustive description of any BIMapplicable classification system. Serving the interests of the constructionelement.industry, Kreo suggests a practical solution to the issue.Moreover, NRM are fully compliant with The Building Cost Information ServiceStill, another question remains unanswered: how can everyone follow the same(BCIS), the most comprehensive cost database in the UK. Both NRM and BCISrules when working with BIM models?are developed by the same institution - The Royal Institution of CharteredSurveyors (RICS).This is a question that is too big for any one eBook to answer, though we willharnessed.sslaic emUn ystSNRco M2desay that only through collaboration can the potential of BIM models be trulyBIMELEMENTIN KREOTo learn more about how you can improve your planning processes throughUPr niclod asuc st1RMN odecNRM2SsClassifiedBIM elementPrimproved team collaboration with Kreo, click the button below to book ameeting with Kreo’s founder, Magomed The collection ofcomponents that gotogether to carry out afunctionA specific material orcomponent of anelementA measured item thatforms part of anelement or asub-elementAn item of work to bemeasuredPurposePurposePurposePurposeBIM elementidentificationBIM elementidentificationCost EstimatingElement BreakdownStructure (EBS)compositionBill of QuantitiesWork BreakdownStructure (WBS)compositionThe Definitive 2018 Guide to BIMClassification SystemsBOOK TIME WITH MAGOMEDNRM1NRM214The Definitive 2018 Guide to BIMClassification Systems15
