Design to Fabrication Workflow

BIM MEP AUS workflow and add-in software

– Improve productivity

– Target zero re-work

Introduce new skills to existing drafting team

9 Networked Design Suite Ultimate (July 2012)

22 CADmep licences nationally

Implementation Plan

“........The single most devastating consequence of modernism has been the embrace of a process that segregates designers from makers.”

Design Shop

Drawing

Utilise and leverage the Design models

Create a constructible Revit Model using BIM MEPAus

Fully coordinate and construct in the Virtual world

Leverage the model for BIM-to-Field

Construction sequencing (4D)

Estimating & Procurement

Phase 3 – Construction / Fabrication

Proven the workflow

Project needs to commit to full BIM, not partial or lonely BIM

BIM MEPAus standards and Add-in enable the workflow benefits

Manufacturer’s content is key

Real leveraging of BIM goes well beyond clash coordination

BIM execution plans are the key

Model management/ distribution is critical

Much more knowledgeable

6-9 month implementation / perseverance

Lessons Learnt

BIM deliverable to the project construction team – preferably using BMA Add-in

BIM Execution Plan for collaborative development of the Design Model through to Constructible Model

Support manufacturer’s content development

Establishment of Robotic Layout System

Programme needs to be adjusted to suit the BIM based workflow and BIM to Field

Communicate & understand
