10 Regulators & Associations Building construction o Government authorities 1. Public Works, Town and Country Planning (DPT) 2. Thai Industrial Standards Institute (TISI) o Statutory organization 1. Council of Engineers (COE) 2. Architect Council of Thailand (ACT) o Associations 1. Academic - Engineering Institute of Thailand (EIT) - Thailand Structural Steel Society (TSSS) 2. Professional - Consulting Engineers Association of Thailand (CEAT) - Thai Contractor Association (TCA) - Thailand Steel Constructor Association (TSCA) 3. Others - Iron and Steel Institute of Thailand (ISIT) 10

11 Product Standard Structural steel products in Thailand are referred Thai Industrial Standards (TIS) TIS107 : Standard for Hollow Structural Steel Sections TIS1227: Standard for Hot-Rolled Steel Sections TIS1228: Standard for Cold-Formed Steel Sections TIS1390: Standard for Hot-Rolled Steel Sheet Piles TIS1303: Standard for Welded Structural Steel Sections TIS1479: Standard for Hot-Rolled Carbon Steel Coil, Strip, Plate and Sheet for General Structure TIS1499: Standard for Hot-Rolled Carbon Steel Coil, Strip, Plate and Sheet for Welded Structure Ref TIS107 Hollow Structural Steel Sections Note That most of structural steel product standards are adopted from Japan Industrial Standard (JIS) Ref: TIS1227 Hot-Rolled Steel Sections Ref: TIS1228 Cold-Formed Steel Sections 11

12 Design Standard For steel structures, most design engineers in Thailand follow the standards from the Engineering Institute of Thailand (EIT) Ref: eitpr.com EIT1020 Steel Design Standard For Steel Section Ref: ubook.msu.ac.th EIT1024 Steel Design Standard For Cold-Formed EIT1020: Load and Resistance Factored Design Standard for Buildings using Steel Sections. EIT1024: Design Standard for Buildings using Cold-Formed Sections. 12

13 Fabrication Standard No steel fabrication standardization authority is yet established in Thailand. The reasons behind are that; The most major steel fabricators focus on export markets, which require international standard per the requirements from their clients. The steel construction for general buildings in Thailand are not very popular, resulting in unavailability of steel fabricators focusing domestic construction market. However, Thailand Structural Steel Society (TSSS), a recently established association, identify their priorities to standardize and establish Thai steel fabricator accreditation scheme, as well as to prepare steel fabrication guideline and quality check list.

14 Construction Standard There is also no construction standard and code of practice yet available in Thailand. So Thai Contractor Association (TCA) has been a key support for the establishment of Council of Thai Contractors, with the main objective to develop required skill sets for construction technicians and to classify level of competency, as well as to obtain accreditation scheme among contractors for particular types of works. Please note that the achievement of Thai contractors is to perform construction works that meet the requirements in the specification and design documents. As a result, the key corporate strategy of most Thai contractors is cost leadership, resulting in the single-path innovation towards process optimization, i.e. no innovation towards design or material optimization as a maker for what is designed. 14

15 Building Codes Steel Applications in Construction Sector Sub-committee The Building Control Act B.E (A.D. 1979). From that point on, the Public Works* under the Ministry of Interior had taken full responsibility to control building construction in Thailand Ministerial Regulation No. 6 B.E. 2527: Load, Resistance Durability, Construction material properties, Modification and retrofit of buildings and Site stability Ministerial Regulation No. 33 B.E. 2535: Criteria and Equipment for Tall Buildings and Extra Large Buildings Ministerial Regulation No. 41 B.E. 2537: Size and Geometry of Parking Structures with or without the Installation of Elevators Ministerial Regulation No. 48 B.E. 2540: Construction Material Properties for Main Structural Members and Glass Panel Ministerial Regulation No. 50 B.E. 2540: Addendum to Ministerial Regulation No. 33 B.E Ministerial Regulation No. 60 B.E. 2549: Addendum to Ministerial Regulation No. 48 B.E Etc.

16 Future Direction Steel Applications in Construction Sector Sub-committee Skilled labor will be more expensive and much more difficult to find. Less labor intensive approach will be a key success factor for construction firms. Prefabricated steel construction would likely be one of contractors preference. Since Internet of Thing (IoT) and Big Data have become key driving forces to the industry, more tools and applications will individually be created in order to effectively communicate with their clients and to obtain better clients insight and needs. New innovation through Building Information Modeling (BIM) will most likely take a major part in prefabricated steel construction for more productivity. The supports from Thai government for normalization of fire protection demand to be as per international standards and standardization of steel bridges for highway constructions will exponentially expand the market size of steel construction in Thailand.
