Andrew BagnallHVAC Engineer & ESD ConsultantGHD NewcastleRevit user since 2007Corporate Coordinator for Revit MEP in GHD
Introduction
Revit Technology Conference 2010
Multidiscipline professional services company est. 1928Approx 6000 staff in 16 countriesA&E practice of approx 2000 staff
GHD
Revit Technology Conference 2010
GHD Sydney’s first foray into multidiscipline BIM – November 2009Most staff coming from a zero Revit experience baseSeries of Laboratory jobs won – call made to deliver in RevitArchitecture, MEP & Structure all to be delivered from one team in one modelAll staff to train simultaneously and on the project!However…Substantial experience existed in nearby Newcastle & Canberra based teamsSubstantial content library already developed corporatelyHighly complex services requirements – perfect for coordination in Revit!
The Scenario
Revit Technology Conference 2010
A series of laboratory buildings

The Projects

Lessons Learnt!
Revit Technology Conference 2010
In large organisations – use A-Team approach:Core group of champions for each disciplineUse to seed new centres of capabilityEnsures consistency in approach across organisation
Training of New Teams
Revit Technology Conference 2010
Entire team should be BIM savvyENTIRE TEAM – yes includes seniors, principals & the client!Lots of meat on the BIM sandwich
Project Team Structure
Principals, Managers, QA
Core Modelling Team
Drafters & Detailers
Revit Technology Conference 2010
Keep it tight!Core of 1-2 modellers per discipline/area at any timeCreate integrated project teams where possibleLocate team in a cluster – or at least the Revit usersAll disciplines in the same package (Revit) for best success

Traditional Approach
Project Team Hierarchy
Revit Technology Conference 2010
BIM Approach
Project Team Hierarchy
Revit Technology Conference 2010
Linked Models vs Single Model??Single Model often better approach for multi-discp projectsLinking – consider splitting by area/wing/zone rather than disciplineSetup sheets at the outset – so drawings always availableStart from an up-to-date multidiscipline template.Appoint a model manager & hold accountable for maintenance
Model Setup
Revit Technology Conference 2010
Discipline your teams on this from the start!Organize view browser to suit projectBe diligent and descriptive in naming viewsBe creative with viewsUse 3D as much as possibleMake use of cropped views and ‘orient to view’
View Setup & Management
Revit Technology Conference 2010
Maintenance Activities:Monthly
Check systems – default, integrity & namesWorksets – check and clean up discrepanciesDelete unused / redundant views or name meaningfully
Weekly/FortnightlyPurge Unused (and encourage a “use it or lose it” mentalityRemake Central with audit
DailyCompact Central
Model Management & Maintenance
Revit Technology Conference 2010
Beware of segregating these roles too much…Engineers / Architects should be working in or with the model‘Modellers’ should be undertaking design decisions as they go, not just reproducing marked up instructions‘Drafting’ tasks – i.e. annotations on sheets, should be reserved for the end stages and can be delegated to appropriate junior staff
Designers Modellers Drafters??
Revit Technology Conference 2010
If markups are necessary – use dwf’s & Autodesk Design ReviewCan be imported into Revit & overlaid
Markups
Vs.
Revit Technology Conference 2010
Preferably avoid the markup model/draft routine completelyUtilise the rich BIM data in the model to aid design decisionsIf necessary have senior designers work alongside Revit savvy staffOr…. Have Revit savvy senior designers
Markups
Vs.
Revit Technology Conference 2010
Don’t ‘draft’ equipment schedules – use the data in the families
Parametric Scheduling…
Revit Technology Conference 2010
Maximise the use of design tools within the Revit platform
Design Tools
Revit Technology Conference 2010
Schedules as Design Aids
Revit Technology Conference 2010
Duct Sizing
Revit Technology Conference 2010
Structural Analysis
Revit Technology Conference 2010
Workshare Monitor – Useful for streamlining editing requestsInstant Messenger / Email with screen grabsTalk around screen!Remote Assistance
Communication & Collaboration
Revit Technology Conference 2010
Make regular use of interference reporting in RevitSet up specific views to use for clash detection to improve clarityFortnightly Navisworks export for rapid walkthroughs / coord meetings
Coordination
Revit Technology Conference 2010
Don’t get hung up on drawings!Educate client and/or team on benefits of model deliveryConsider “drawing-less” delivery for prelim stagesAutodesk Design Review & Autodesk NavisworksMaximise use of information from model on sheetsIssue 2d & 3D in .dwf format to preserve info & filesize
Deliverables
Revit Technology Conference 2010
Coal Mine Feasibility Study – ‘Drawing-less’ Delivery
Revit Technology Conference 2010
What Worked Well?Communication was excellentTeam hierarchy and dynamic altered & improvedCoordination meetings improved out of sight vs. 2D
What worked not so well…Engineering disciplines still adhering to the designdraft mentalityToo much doubling up of processesFull information capture still not quite happeningTiming of work activities needs to be brought forward
