PREFACERider Levett Bucknall (RLB) is an independent, globalproperty and construction practice with over 4,000people in more than 120 offices across Asia, Africa,the Americas, Europe, Middle East and Oceania.Services provided include Cost Management andQuantity Surveying, Project Management andAdvisory Services.RLB fully embraces Building Information Modelling(BIM) and has the capability to work within a BIMenvironment across all of our service areas. BIMrepresents a huge opportunity for our industry toimprove the effectiveness and efficiency in variousaspects of design, construction, operation andmaintenance. We fully support collaborative workingenvironments, to enhance transparency and risingstandards within the built environment.5D BIM includes the addition of cost data to theinformation model. Cost-related information mayinclude capital costs or construction costs, therelated running costs as well as the replacementcosts. 5D BIM is often adopted in value engineeringexercises to evaluate the cost impact of differentdesign options and to allow designers in identifyingthe optimal design solutions effectively andefficiently. It also facilitates change management andprovides visibility of changes before any decision ismade.Promoting the implementation of 5D BIM, thisdocument is compiled to outline the informationsuggested to be included in BIM models for thepurpose of Quantity Take-off (QTO) from detaileddesign stage to the completion of the project. TheStandards shall be regarded as a communicationbridge between the quantity surveyor’s measurementrules and the BIM naming convention.Rider Levett Bucknall RLB 5D BIM STANDARDS FOR USE IN HONG KONGI

GUIDANCE NOTES FOR DESIGN CONSULTANTS1.The 5D BIM Standards (hereinafter called“Standards”) will provide a basis for discussionbetween the quantity surveyor (QS) andeach design discipline to work out a practicalapproach amongst the stakeholders to developa model that can serve different purposesincluding QTO and cost management. Deviationsfrom the Standards can be agreed based on theresult of collaborative discussions to suit therequirements of a particular project.(b) Sub-element (By Heading): These are theheadings usually adopted in individual BQ.2.The modelling approach and graphical details arenot mentioned in the Standards.Sections for both Architectural, Structural Worksand Building Services Installation3.All columns in the ten Sections of the Standardsunder the heading “General BQ/SOR” highlightedblue are related to items in the Bills of Quantities(BQ)/ Schedules of Quantities and Rates (SOR)prepared by QS, whereas all columns underthe heading “Naming Convention” highlightedgreen are related to the corresponding namingconvention suggested to be adopted by designconsultants in models.4.(c) System Name: These are commonly used forthe naming of individual BQ.(d) Sub-System Name: These are the headingsusually adopted in individual BQ.(e) BQ/SOR Item: These are the bill itemsin individual BQ. Keyword search mayhelp to identify the target object andthe corresponding suggested “NamingConvention”.5.Sections for Architectural and Structural WorksIIFor the “Dimension Attribute” under the “NamingConvention”, it is suggested to adopt “LabelDimension” and parametric modelling suchthat the shape of the model geometry will bechanged accordingly upon the dimension valueunder this column is modified. This could avoidinconsistency between geometry and nongeometrical information.8.For the “Additional Attribute” under the “NamingConvention”, it is suggested to adopt “SharedParameter” and “Instance Parameter” insteadof “Project Parameter” and “Type Parameter” inorder that the information input in models canbe extracted for QTO purpose.9.For void/ opening, it is suggested to use regularopening family (i.e. Generic Model) availablein Revit Libraries with dimensional informationprovided. “Edit Profile” mode is not suggested tobe used, unless unavoidable.Sections for Building Services InstallationThe sub-columns under the heading “GeneralBQ/SOR” highlighted blue are described asfollows:-(a) Element (By Bill): These are in generalidentical to the sections in Hong KongStandard Method of Measurement of BuildingWorks – Fourth Edition Revised 2018. Theseare also commonly used for the naming ofindividual BQ.7.6.All columns in the ten Sections of the Standardsunder the heading “Naming Convention”highlighted green are related to the suggestednaming convention in ensuring the BIMobjects are named systematically, logically andconsistently for better understanding by modelusers and for easy BIM object management andinformation exchange. The suggestions maybe varied to suit specific project needs and thepractice of design consultants.The Naming Convention in the Standards focuseson the functional/ informational requirementsinstead of the naming format.Rider Levett Bucknall RLB 5D BIM STANDARDS FOR USE IN HONG KONG10. It is suggested not to have void/ openingfor “extra over” items listed in the Standards.Otherwise, it is recommended to have an“Instance Parameter” for “Opening” with Boolean(Yes/ No) option to be added under “AdditionalAttribute” for indication.11.It is suggested to modify the “Constraints” and“Offsets” parameters in “Properties dialog” incontrolling the top and base of the Wall. “EditProfile” mode is not suggested to be used, unlessunavoidable.

QS may propose to thedesign consultants to provide “Size on plan” forthe calculation. However, if Category of “Floors”is used, “Area” under “Dimension Attribute” shallmean the actual area of that sloping surface.
