Class Summary

� Often BIM requirements are driven by the owner or developer who is interested in getting the 6D (Facilities Management) benefit at the end of a BIM delivery process. This class will describe the challenges and level of integration required between all parties involved in the process (general contractor, subcontractors,

quantity surveyors, and design consultants).

� The key goal will be to highlight the importance of a continuous delivery

process at levels, gradually building towards the final 6D target.

� Using real project scenarios, we will demonstrate how to put the pieces of the puzzle together and analyze the consequences and impact on all parties involved at different stages of the project.

� Why BIM?

Internal benefits to individual parties

� Why 6D?

Owner or developer requirement

� What is 6D?

Model information to enable facility management and maintenance

� What are the consequences?

Financial and workflow Impact on designer, fabricators and builders

� Capabilities of technology

Technology can support all aspects of the delivery process

(3D, 4D, 5D)

� Challenge: Connecting the dots

Get everyone working toward a common goal without compromising the advantages of using

BIM for each speciality

� Design Monitoring Process Concept

� The why’s

� The quantity of design documents to review is enormous.

� On the Sports Hub, the contractor iis the main co-ordinator.

� How do we effectively demonstrate to the consultants that the design is not as co-

ordinated as the consultants would like us to believe

� The how’s

� Through this system the process of co-ordination is demonstrable and trackable.

� We are using this successfully on the NST, AQC and MPIA and will soon roll it out to all

buildings.

Issue Highlighted by DSPL. Opening in Wall Missing

The revised model is inserted into the same view and we see that the consultant has fixed the issue.

On the schedule we change the status from “issue outstanding” to “issue resolved” and the relevant comment in the report changes from red text to grey text.

� Visualisation


� Impacts

� Better reactivity to the design coordination problem

� Better collaboration between the consultants and the main contractor

� Better confidence in the post process such as the QTO or Set-outs drawings

and so on

Situation 2: Using a consultant Revit model for

costing purposes

35

Situation 2: Using a Revit model for costing purposes

� Project requirements

� Model and workflow established for coordination

purposes initially

(Architecture, Civil, Structure MEP)

� Challenges

� QS performing quantity take-off from the models

� Models enabled to support their requirements

36

© 2011 Autodesk


� Solution implemented

� Analysed the scope of work to comply with the new

QS requirement

37

© 2011 Autodesk



� Reviewed information in current models

� Understand the interoperability between Revit

and the costing software

Had no other choices than to remodel

all the structural elements

38

� Impacts

� Delivery schedule

� Human impact (frustration)

� Financial impact

Situation 3: Managing the services openings

(CBW) request process

40

© 2011 Autodesk

Situation 3: Managing the CBW requests process


� CBW accuracy and traceability

� Collaborative work with Structural and Architectural department

� Challenges

� Getting builder’s work holes in the right place on a large project is very difficult and the

failure to get it right is one of the biggest causes of rework in the construction process:

� More labor, more time, more cost

� Loss of opportunity to focus on critical path activities

� With BIM we can improve the proportion of holes which are cast/cored/cut in the right

place first time.

� Impacts

� Less labor, less time, cost effective

� Better opportunity to focus on critical path activities

With BIM we can improve the proportion of holes which are cast/cored/cut in the right place first time.

Situation 4: SOA and Room Data Sheets in a

contract maangement sense

49

© 2011 Autodesk

Situation 4: SOA and Room Data Sheets


� Deliver according to the contract

� Prove that the building is comp[lying with the contraact

� Challenges

� Long and manual process if performed on the as built documentation

� Cost factor associated to the rectification of some parts of the building to match the

contract

� Constant negotiation with the client in a pressure period of the prpject just before final

delivery.

� Linked the Revit Model to the Contract

� Visualied the problems graphically with the help of the model

Conclusion

60

� To be successful in delivering a 6D process:

� Establish collaborative workflows as part of your

BIM execution plan

� Ensure project’s workflows and process remained

in check at all times
