• “Our results come out very close (within 10-15%) to the bottoms-up total that your group developed.  So, in my opinion this is a very good verification that the base for your cost model is good.

• Based on the file I sent you with the preliminary findings of our independent review, an uncertainty on the order of 25%-30% seems reasonable.

Collaboration with CIFE

• CEE 211 class “multidisciplinary modeling and analysis”

• Used the ILC equipment installation plan as a case in this class

• Project team: two graduate students (Esther Kweon, Jung In Kim) and Jonghoon Kim

• Goal of this case study– To explore the possibility of increasing the certainty of equipment installation

plan in ILC project– To test if the following software tools that enable 4D model based time-space

conflict detection and analysis are suitable for our project

• Software tools used and the capabilities of the tools tested– AutoCAD (3D modeling)– CATIA (3D modeling)– Primavera (Scheduling)– Navisworks (4D modeling and time-space conflicts detection)

Project results

• An example of time-space conflict in the original installation schedule

• Improved installation schedule– Decreased time-space conflicts– Same total duration

Original Schedule Alternative Schedule

Working on mitigationSequence change between “Supply and exhaust ventilation”, “Beam line”, “Fire suppression, and “”Chilled water skid and

piping”

Number of time-space conflicts 236 170(30% decreased)

“Fan Coil unit installation” and “piping installation” is too close and have a time-space conflict

Conclusions

• 4D-based time-space conflicts analysis can– Detect unpredictable time-space conflicts of equipment installation schedule– Provide detailed information about detected time-space conflicts

• Equipment and activity list that conflict each other

• Times of the time-space conflicts detected

• Locations of time-space conflicts detected

• Severities of time-space conflicts detected

– Visualize installation process and detected time-space conflicts– Make clear where the installation schedule needs to be improved– Consequently, enable planner to increase the certainty of equipment installation

plan

• Software tools that we used and tested are suitable for installation schedule optimization in our project

• Next, to test the above software capability to check for possible interference during the transport and installation of equipment
