Approach – All Disciplines

Observation• Coaching lessons required• Models built with schedules, rendering, walk through, construction

sequencing, etc.• BIM supports PM – planning, coordination, safety review, monitoring, etc.• BIM supports Client – virtual construction, site review

Deliverables at Project Level

Way Forward Identify Achievements

• Shop Drawings• Coordinated CSD / CBWD• Track Change Log / Change Histories*• Schedules of Quantities (QTO)#

• Progress Monitoring

* Change histories include all kinds of information received either through formal instruction or verbally or just a free hand sketch

# Quantities not necessarily 100% taken from BIM model. e.g.

formwork QS Approachconcrete BIM Approachrebar Engineering Approach

Virtual Construction Review

• Better study of construction programme & details• Work Environment study to improve safety• Clash analysis to resolve problems

16

Use for Project Handover

Way Forward BIM to Client / FM Team

• As-built Records & Drawings• Asset ID with Details• Form Part of Operation & Maintenance Manual

17

Setup for Long-term• Enhancement of modelling techniques• Library setup• Company standards establishment• Regular coaching by BIM consultant• 4D & 5D applications by BIM consultant• BIM Modelling as management toolsBIM Modelling as management tools

Way Forward Long-term Development

Checking & Monitoring• Audit system setup for regular review• Monthly report submission to PM by BIM consultant

- with findings & recommendations- follow-up actions by PM

BIM Run Thru Project Life Cycle

• BIM step in from DesignDesign• Allow early collaboration across disciplines• Clash analysis on critical elements• Identify potential construction constraints• Review on buildability & appropriate construction method

Design Stage

Construction Stage

• Virtual construction • Simulation on site planning for resources management• Identification of site issues -- reduce abortive work• Safety review & training

• Training• Coaching after Training

• Platform for Practice

• Start with something SimpleSimple• Step by step approach

BIM Is Not Difficult
