用BIM改造水泥厂建设

H O L T E C C O N S U L T I N G( K a p i l G o y a l ) Key Insights of the webinar To highlight the challenges faced in cement plantconstruction.To demonstrate how BIM (Building InformationModelling) addresses these challenges throughadvanced digital tools.To showcase the advantages of BIM in improvingefficiency, safety and cost-effectiveness.To present Holtec’s expertise and experience inimplementing BIM in cement industry projects.

Typical cement plants require80,000 and 120,000 cu m ofRCC for foundational andbuildings.Size of structure varies fromsmall electrical load center toPreheater (26m x 36m x 150mHigh).All building are havingequipment and machinesupports inside. Typical cement plantsrequire about 12,000Metric Ton of Structuralsteel fabrication anderection.Structures are complex asthese support Ducts (which are not straight) ,maintenance platformandcables. KEY CHALLENGES IN ENGINEERING Receipt of input in phases Improperly phased/delayed ordering of equipment impactsproject timeline Dimensional Clash Revision of Drawings Mismatch between mechanical GA andcivil construction drawings or with steelfabrication drawings. All stake holders to work onlatest revision of drawings Structural Fouling Improperly conceived GA may result infouling of ducts with equipment or withstructural members INTRODUCTION TO BIM(BUILDING INFORMATION MODELING) Define BIM asa digitalbuildingrepresentation BIM is the digital representation of thephysical and functional characteristics ofabuildingfacility,servingasacomprehensive information resource. Enable integratedprojectvisualization &collaboration BIMfacilitates teamwork by allowingstakeholdersto visualize the entireprojectandcollaborateefficientlythroughout the construction process. Recognize BIM asa transformativeconstructiontechnology Emerging over the last two decades,BIM is revolutionizing the constructionindustry by enhancing design,planning& execution phases. WHY BUILDING INFORMATION MODELING?KEY BENEFITS TO MEET THE CHALLENGES Holtec prepared and made all the Latest models available on cloud to all the stakeholders. Cloud services for theBIM was provided by the client only for having better control over the data as an OwnerLatest drawings and relevant data are also available on cloud to avoid any confusion at site.Due to phase wise availability of information, the frequent revision is confusing. This can lead to errors andmismatches . As per our experience the same is better taken care using BIM. There are different stakeholders in the construction of cement plant like mechanical supplier , civil and structuralengineer and electrical engineer.Conventionally all of them work in their separate and isolated environment.Flow of information and changes is not smooth in conventional methods, hence there are chances of errors andmismatches.We have implemented BIM in certain disciplines and found the flow of information very smooth.Using tools for clash check , we could by and large remove major site problems.There were lesser mismatches and no clashes in the drawings .i.e between civil , structural and Mechanical. FLOW OF BIM ENGINEERING INCEMENT PLANT 10 steps in BIM engineering in cement plant Technical conceptdevelopmentFlow sheetMass flow diagramPreparation of tenderdocumentReview of tender and ordering 2.PRELIMINARY LAYOUT PREPARATION a)Deciding different levels / benches as per terrainrequirement. Prime objective is to optimize the earthwork,keeping in mind Accessibility to each areaSlope of roads for loaded truck movementDrainageEase of maintenanceLower operational cost 2. (Contd.) PRELIMINARY LAYOUT PREPARATION b) Detail Calculation of earthwork is done using software which shows volume of cutting and volume of filling in theselected area on adoption of certain level bench. This also tell the level of bench at which cut, and fill are balanced. 2. (Contd.) PRELIMINARY LAYOUT PREPARATION c)Trying out different location of the buildings in 3Dlayout. We can place the different blocks in the layout atdesired location. We can easily change the location andtry different optionsd) Checking out Erectability of equipment and Structures 3.
