1 Viterbi School of Engineering. USC Application in Construction

2 Viterbi School of Engineering. USC Why automate construction? Labor efficiency is alarmingly low Skilled workforce is vanishing Work quality is low Control of the construction site is insufficient and difficult Accident rate at construction sites is high (> 400,000 / year in US) Waste and trims are high (3 To 7 tons per average home; 40% of all materials used worldwide are for construction) Low income housing and emergency shelters are critical Construction is the largest sector of almost all economies All other products are fabricated automatically – construction is still largely a manual task

3 Viterbi School of Engineering. USC Construction productivity decline Labor productivity comparison for non-farm industries and construction industry developed by Paul Teicholz Construction Productivity index Non-farm productivity index

4 Viterbi School of Engineering. USC Edisons concrete houses $175,000 for molds More than 2000 pieces 500,000 pounds

5 Viterbi School of Engineering. USC Automated construction in Japan 89 single task construction robots 11 different automated construction systems Concrete Surface Treatment Robot This robot absorbs the water which remains after concrete has been set.

6 Viterbi School of Engineering. USC Big-Canopy high-rise pre-cast concrete construction system. Used to construct the 26 storey pre-cast concrete 30,726m 2 Yachiyodai Condominium building in Japan. The system realized a 60% reduction in labor requirements for the frame erection.

14 Viterbi School of Engineering. USC What constitutes construction cost ? PortionDue toIf Automated by CC 20%-25% Financing Short project length and control of time to market will dramatically reduce this cost 25%-30% Materials Will be a wasteless process 45%-55% Labor Will be significantly reduced
