11 CURRENT SITUATION Based on the study the cost effectiveness of steel construction in economics aspects performed by ISIT in 2008, it can be concluded that RC cost (baht/m 2 ) 1, RC vs. Steel 18 cases each Concrete 2,550 baht/m 3 Steel cost (baht/m 2 ) 2,034-3,383 Span No. of Stories Live load Rebar 19.5 baht/kg % More expensive 17% No fire proofing 4m 6m HRS 25.0 baht/kg 8m Labor 220 baht/day

12 CURRENT SITUATION Based on latest unit cost together with following assumptions. % cost of steel rebar in RC structure 40% % Labor cost 2008: 30% (expensive material + cheaper labor) Concrete 2,550 baht/m 3 Rebar 19.5 baht/kg 28 Rebar 42 Conc. 70 MAT. Steel 82 HRS 25.0 baht/kg Labor 30 Labor 35 Labor 220 baht/day RC (2008) = 100 STL (2008) =

13 CURRENT SITUATION Based on latest unit cost together with following assumptions. % cost of steel rebar in RC structure 40% % Labor cost 2008: 30% (expensive material + cheaper labor) Concrete +12% 2,850 baht/m 3 22 Rebar 47 Conc. 69 MAT. Steel 64 Rebar -23% HRS -22% 15.0 baht/kg 20.5 baht/kg Labor 45 Labor 53 Labor +50% 330 baht/day RC (2016) = 114 STL (2016) =

14 CURRENT SITUATION Conclusions from the above More optimization (value engineering) can be applied to steel structures than concrete structures. Design skill and construction efficiency for concrete structures are about to reach the best possible practices for Thai engineers and constructors. High strength steel (Fy > 360 MPa) and innovative form of steel structures have been introduced to construction market. Construction cost of steel structures will no longer be much more expensive than reinforced concrete structures. Steel price in foreseeable future will unlikely be reaching steel price in Labor cost will never be reduced, however will be subject to political situation. Concrete cost will gradually increase based on labor cost, energy cost, etc. Note: Steel construction has prevailed factory & warehouse segment, as well as petrochemical segment. Therefore, it is reasonable to address segments at which steel construction has potential growth. 14

15 CURRENT SITUATION FACTS Some home builders have started implementing structural steel construction. Prefabricated concrete load bearing wall system, which has been well developed recently in Thailand, will not be used by homebuilder sector because it is not economy of scale. Homebuilder believe that steel framing will eventually be replacing RC framing. Therefore, the sooner they start, the more skills they will gain. Prefabricated steel framing can be erected from the ground up within 7-10 days, which is much faster than RC beams & columns since formworking, shoring and concrete curing are all time consuming process. However, faster steel construction could not pick up construction speed because brick wall manual construction was time consuming. 15

17 FUTURE TREND Shop fabrication + Field installation system Prefabricated wall panel system with insulation capability 17

18 FUTURE TREND Shop fabrication + Field installation system Prefabricated wall panel system with insulation capability Prefabricated Prefinished Volumetric Construction (PPVC) 18

19 FUTURE TREND High strength steel products Seismic resistant steel structures Steel bridges for Highway Construction 19
