BIM Journey Not a project requirement. Instigated by the BMPX acting as the D&C Contractor. Not by the Client or Anchor Tenant (QLD Government). REVIT Architect, Services Engineer and Structural Engineer.

BIM Journey Services design produced in 2D CAD until the tender documentation stage. Mechanical tender documentation in REVIT. Electrical, hydraulic and fire services documented on 2D CAD with REVIT model as a guide for co-ordination purposes only.

Post Tender design development EMF Griffiths retained to complete the mechanical design. Remaining services 80% designed, the remaining 20% to be documented by the specialist D&C sub-contractors.

BIM Co-ordination EMF Griffiths as mechanical designer took on the ‘BIM’ coordinator role and lead weekly coordination workshops as the using Navisworks. Participants issued models 24hrs before the meeting. Meetings held for 8 months, initially 6hrs reducing to 2hrs as the design was refined.

BIM design workload 60% Modeling 40% co-ordination and management

BIM Co-ordination Coordination workshops attended by specialist BIM modelers & specialist design engineers. Key to achieving an effective model which accurately depicts practical compliant engineering systems

Lower Ground Overview

REVIT benefits Know it works, don’t just think it can be made to work. Initial input time consuming, but impacts of changes are realised more quickly. Upfront problem solving. Navisworks model available on site Lower project risk!

16

REVIT benefits Management of sub-contractors. Upfront problem solving.

17

Navisworks available on site to aid decision making.

REVIT - Disrupting the status quo! The balance of effort between the Design Team (input) and the Construction Team (output) fundamentally changed. Bucking the recent trend.

18

REVIT MEP is continually improving but is often frustrating. Shortage of experienced modelers.

Design to Fabrication Specialist services sub-contractors not directly using the REVIT model other than for clash detection through Navisworks. They are using independent specialist fabrication ‘BIM’ tools which export files for incorporation into the Navisworks model.

BIM’s future a Design Engineer’s dream

A single model which EFFECTIVELY allows a single data input to analyse: 1) Thermal loads 2) Façade performance 3) Day-lighting 4) Electrical Lighting 5) Energy consumption

BIM’s future an Engineer’s view

Greater industry familiarity will increase knowledge of the benefits and reduce associated costs. This has been demonstrated by the GBCA Green Star initiative. EMF Griffiths recently completed 100 Green Stars that is our projects Green Star’s tally 100. We’ve noticed a huge difference in the market’s perception of the associated risks .
