Case Study 1

Motivation & Background Case Study 1

• What are the repercussions of using a drilling robot on site? What are the potential benefits? -40hs, +$29K

• What are the planning activities and workflow required? Collect design information, automate hanger-placement, and clash detection (+10d)

• What are the safety and quality differences? 98% reduction on muscle strain hs, -50 clashes

• How does it affect decision making? Until 1 day before to make changes

• How many product, organizational, and process boundaries have to be crossed to make a robot cost-and schedule-effective? 4 main boundaries

Research answers

Motivation & Background Case Study 1

EXTRA COSTCHANGES IN WORK PROCESS ANDCOORDINATION TIME

INCREASE LEVEL OF BIM DEVELOPMENT

ORGANIZATION CHANGES (PROJECT PARTICIPANTS)

Social acceptance of technologyAvailability of human resources

Automation benefits:Safety and qualityCalendar time reduction (scale)

Technical feasibility Extra clash detection and prefabrication

Faster installation (33% reduction thanks to pre-drilled holes)Predictability

MANUALROBOT

Motivation & Background Case Study 1

Product, process, and organizational barriers

Lack of manual drilling metrics

Variability

• Drilling and installation rework• Overtime work• Number of clashes• Percent plan complete

• Waiting time to access a zone• Sequencing and use of resources• % manual rework • Adoption of new technology• Project zones and accessibility• Diameters used for robot

Observed analysis challenges

Motivation & Background Case Study 1

1. Shorten the effort and duration for coordination of robot work

2. Consider the scale of the project and the key benefit for automation (shorter duration, safety, quality, reliability, other?)

3. Obtain benchmark data of manual and robot work to back-up the decision

Recommendations

Motivation & Background Case Study 1
