AbstractHow has Building Information Modeling (BIM) impacted the design and construction process? How does this affect the lighting industry and the workflow between lighting designers, architects and engineers? In this presentation, well discuss strategies for effective collaboration using Autodesk Revit and utilizing the data within a building information model for downstream uses.

Learning ObjectivesDescribe the pros and cons of different Revit workflows between architects, engineers and lighting designersUnderstand how to avoid common problems exchanging Revit modelsEffectively utilize the data in a Revit model in the design phaseUnderstand how the data in the Revit model can be used beyond the design phaseUnderstand the COBie standard and why it's important

Why Building Information Modeling?

Autodesk RevitCommonly Used BIM platform in the USAvailable via subscription (current version + 3 previous)Design Suite Premium (Revit, AutoCAD, 3ds Max, Navisworks) $340/month, $2,730/yr annual commitment per licenseRevit Collaboration (Revit, AutoCAD, BIM 360)$315/mo, $2,500/yearPerpetual Licenses (not available after July 31 2016): $6,825, add $1000 for cloud services and previous versionsRevit LT is NOT a good option-doesnt offer lighting toolsRevit is NOT backwards compatibleYou must use the same version as the rest of the teamThere is no saving down

PC SpecsSpend money on processor: Core i7 or XeonRAM is cheap, so MAX it out.General rule: file size x 20 = amount of RAMSolid State Drive is a necessityDedicated GraphicsUseful for working in 3dGaming cards work well and are significantly cheaper than Pro cards

Typical WorkflowEveryone on a team works in one modelCentral File = lives on office serverLocal File = lives on user workstationRevit keeps track of every element and who borrows it to make changesAll views, sheets and schedules live in this one model

Explain the copy/monitor workflow. Architects may start laying out lights in their file lighting designer can copy that into their file but also monitor its location. The monitor can work both ways if either architect or lighting designer shifts a fixture, each is notified. Copy/monitor can also map fixtures. Architect could use a fixture that renders accurately while a lighting designer could use a more generic fixture.10

Typical WorkflowSeparate models for each discipline Architectural, Mechanical, Electrical, Plumbing all separate filesLighting Designers typically control their own modelArchitects and Engineers may Copy/Monitor fixtures for their own use

Typical WorkflowLighting Designer links in Architectural Model (Origin to Origin)May use Copy/Monitor for initial fixture placementThree Strategies to place new fixtures:Face-Based Objects Hosted to Architectural ElementsPRO: Can attach to: ceilings/slabs/walls in Architectural modelCON: If host is deleted, object is orphanedFace-Based Hosted to Reference PlanesPRO: Reference Planes live in lighting model onlyCON: Still requires manual coordinationFree Floating ObjectsPRO: No risk of becoming orphanedCON: Must coordinate heights manually

A360 Collaboration for RevitRevit Models live in the cloud access from anywhereLighting Designer can now work directly in Architectural and/or Electrical model in real-time should they?$100/month/user or $800/yr (in addition to software cost)

This is where things are going.13

Where to Get Content?Autodesk Seek: seek.autodesk.comBIMObject: bimobject.usBIMStore: bimstore.comManufacturer WebsitesMake your own custom libraryConsistent graphic standardsConsistent parameter information for scheduling

What Makes Good Content?Not too heavy not every screw is modeledProper IES informationFace-BasedTip: Create as non-hosted and then nest in face-based templateDetail Levels properly definedMaterials defined2d Graphics in 2d ViewsElectrical Connectors

Good Content: Example

Clean 2d-graphicsNot over-modeledProper IES informationElectrical Connector

SchedulingWhen possible, schedules should be generated from model elementsSchedule structures can be re-used across projects, so include fixture schedule in a templateEditing data in a Revit schedule is tedious look for add-ins to allow export to Excel and re-importIf schedule lives solely in Excel, Ideate Sticky can link into Revit with format intact

Importance of DataOwners are looking at extracting BIM data for operationsGuidelines defined in a BIM Execution PlanCOBie = Construction Operations Building Information Exchangestandard for data exchangeWarranty Information, Expected Life, Replacement Cost, etc.COBie deliverable is a spreadsheet generated from the model IFC (Industry Foundation Classes) = openBIM file format
