Since start of trial in FY 2012, number of operations and construction projects utilizing BIM/CIM steadily increased. MLIT set goal of applying BIM/CIM principles to all public works projects except small-scale projects by FY 2023 and gradually expanding application. Full-fledged ICT-based construction work starts as part of promotion of i-Construction measures that began in FY 2016. DX Promotion Headquarters for infrastructure sector launched July 2020 to transform social capital and public services. DX Data Center being built with minimum display functions to utilize BIM/CIM and Web conferencing function for shared display of 3D data.

buildingSMART Japan is Japan Chapter of buildingSMART International aiming to create standardization to enable effective interoperability among software to use throughout building’s lifecycle. Vision: Enabling interoperability of construction industry. Throughout lifecycle of project defining and promoting use of specification of shared data used in software/application in each industry and public relations activities. Non-profit organization with open membership requirements, collaborative organization, decision making by consensus, public disclosure of research findings, international solutions, definition of standard specifications through collaboration between software experts and construction industry experts, publication of specifications.

Tokyo 2020 Olympic Stadium designed by renowned architect Kengo Kuma is prime example of BIM in action. Project utilized BIM for design coordination clash detection and construction management. BIM helped streamline construction process ensuring stadium was completed on time and within budget. Stadium cost 157 billion yen ($1.4B USD) with 68000-seat capacity completed 2019 construction began December 2016. Designed by Kengo Kuma Azusa Sekkei and Taisei Corporation. Features large roof eaves encourage air circulation oval-shaped design three tiers of seats beneath partially covered roof made from steel and latticed wood. Sourced 70000+ cubic feet timber from each of Japan’s 47 prefectures. Design inspired by Tokyo’s Edo-period temples.

Guesthouse constructed 2015 by Nikken Sekkei residential building designed as continuous spiral space flowing from approach to bedrooms. Whole structure exists as interconnected space with different elevations. Two-storey building stands on slope descends about 7 meters from road to lake. Architects used Archicad BIM CAD software from early stage to help produce 3D study model. Benefits: Better visualization – 3D BIM model helped architects visualize view of lake from building felt as though actually within structure. Analysis – software helped architects analyze best location for building within site scale of rooms shape and size of openings. Seamless collaboration – 3D BIM models clients and contractors better understand space and design intent.

Narita International Airport opened new terminal March 2015 for low-cost carriers. Designed to handle rapidly expanding budget airlines terminal handles 7.5 million passengers and 50000 aircraft movements per year. BIM software ArchiCAD used to realize structure. Benefits: Planning of structural design and MEP – traditionally concepts and final product require significant timeline development communication coordination execution BIM helped various stakeholders plan structure design MEP in single design. Detailed checks – BIM allowed structure visible from all aspects helped architects check safety of public building.

Ministry of Land, Infrastructure, Transport and Tourism established Japan Construction International Award (honored by Minister of MLIT) in 2017. Held three times up to present as symbol of Japanese quality infrastructure commends construction projects demonstrated Japan’s strengths along with small and medium-sized construction companies. Aims raise further awareness of quality infrastructure promote global understanding. Technology transfer: Japanese technology local engineers/technicians expect boost in skills and capacity improved productivity. Construction methods from Japanese corporations incorporated as standard in other countries contributing towards improvement of overall technical capabilities. Advanced technologies which have never been used before in country can be introduced.

Platform for stakeholder articulation and knowledge management around construction sector digitalization to increase company productivity and construction activity competitiveness. Vision: become 2025 national reference and technical authority for BIM use in Colombia. Objectives: promote digital transformation, develop strategic implementation agenda for all value chain actors, provide BIM adoption tools, support training framework and technical competencies, support national BIM policy and strategy development. BIM KIT: compilation of documents guiding companies step-by-step for successful BIM implementation, articulating all BIM actors in common language, leveling knowledge through technical documents.

BIM Forum Colombia BIM KIT: Guides for BIM adoption in organizations. Developed considering different international BIM modeling standards and guides plus experience from participating companies. References buildingSMART Spanish Chapter, CPNAA graphic standards, National Institute of Building Sciences buildingSMART Alliance US National CAD Standard. Defines modeling levels in BIM Execution Plan (BEP), covers architectural/structural levels, cover/foundation/structure independent levels, level divisions for multi-story elements. Comprehensive framework for standardized BIM modeling practices.

BIM Forum Colombia guide based on Project Execution Planning Guide v2.1 (Penn State). BIM working group developed basic BIM uses workflow for companies initiating BIM implementation. Covers: 3D coordination/clash detection (eliminate design rework, field conflicts before installation), 4D simulation (phased occupancy, construction sequence, site space requirements), design review (stakeholder feedback on 3D models for aesthetics/functionality/technical requirements), quantity takeoff and cost estimation (accurate quantities throughout lifecycle, cost variation analysis). Productivity increase throughout project lifecycle.
