Cavemen wielding ipads! image source = caveman Hong Kong Approach The BIM implementation in Hong Kong s construction industry by CIC is taking both: Push Strategy = advocate project clients and asset owners to adopt BIM Pull Strategy = facilitate industry-wide buy-in and industry-wide ready 12

2 Roadmap for BIM share experience of construction industry practitioners using BIM in Hong Kong; present the industry s views and concerns on the adoption of BIM; realise the global trend toward adopting BIM in the construction industry; summarise the benefits and constraints of adopting BIM in Hong Kong; help industry stakeholders prepare to voluntarily adopt BIM; propose the way forward for strategic implementation of BIM in Hong Kong.

7 3 Key Initiatives Client defined Project BIM Requirements & Deliverables Architects, Engineers, Surveyors MUST generate & use the Models & Data Using BIM PXP to hand the design stage models & data to the Contractor Client Defined BIM Deliverables CIC BIM Standards are intended to be used by Clients to; define the scope of work for a BIM process, define the responsibilities of the project participants identify the deliverables from the BIM Process for the overall benefit of the project and owner.

8 Client Defined BIM Deliverables Planning, implementation, management and checking of the use of BIM on a project requires Client direction, involvement and leadership along with design consultant and contractor collaboration. Every project must have a clearly defined outcome from the BIM Process. Client Defined BIM Deliverables Project Information Client BIM Requirements BIM Management BIM Process BIM Procedures Hardware & Software

9 Client Defined BIM Deliverables Strategic Objectives for implementing BIM Level of development (LOD) List of BIM deliverables for each project stage Each disciplines responsibilities Co-ordination and clash detection procedure Collaboration and Model Exchange Process Schedule of Information & data to be included in BIM Definition of the co-ordinates and origin system Schedule of software formats BIM Uses Definition Client shall specify which BIM uses and deliverables will be implemented on a project. 19 BIM PXP shall identify which consultant or contractor will be responsible for producing the required Models for each stage of the project. The objectives and uses for BIM shall be defined at the start of the project as it will be difficult to implement additional functionality in the BIM models later

12 Design Authoring The process of using BIM software to create and develop a Building Information Model of a project which includes a database of properties, quantities, means and methods, costs and schedules. The architect, engineer, contractor and sub-contractor shall use the authoring tools to produce plan, elevation, section, detail, fabrication and shop drawings. The tools may also be used to produce schedules (room, door, window, finishes, etc). This applies to buildings, civil engineering and infrastructure projects and includes architecture, structure, building services and utilities. Design Review A process for stakeholders (client & users etc) to view a model, images from the models or animated walk-throughs of a project, provide feedback and validate numerous design aspects such as meeting client requirements and previewing spaces and layouts in 3D. The reviewer can check layout, sight lines, lighting, security, disabled access and egress, way finding, ergonomics, acoustics, textures and colours, etc. The review can be done by using computer software only or with special virtual mock-up facilities, such as CAVE (Computer Assisted Virtual Environment) or immersive lab. Virtual mock-ups can be performed at various levels of detail depending on project needs.

13 Existing Conditions Modelling The process of creating a 3D model of the existing site conditions. The model may be developed from laser scanning, photogrammetry, conventional survey methods and record drawings. For historic graded buildings, the author may include a heritage documentation and assessment Site Analysis A process in which BIM and GIS tools are used to evaluate a site to determine the most optimal location, position and orientation for a future project. The analysis shall include master planning, sun and shadow studies, daylight analysis and solar envelope analysis.

14 3D Coordination The process of using Clash Detection software tools to identify conflicts by analysing 3D models of the different building systems. The goal of the coordination process is to eliminate clashes before construction of the project. The 3D coordination process shall include checks for headroom requirements, working spaces for building operations and maintenance activities. Cost Estimation Accurate quantity take-offs may be extracted from models and used by quantity surveyors to develop cost estimates for a project. The quantity surveyor shall extract the data from the models provided by the architect and engineers.

15 Space Programming A process in which a spatial program is used to efficiently and accurately assess a design layout model in regard to client spatial requirements. The model may be analysed for compliance with building codes and regulations. Phase Planning (4D Modelling) A process of linking a programme to the model which is used to plan the phased occupancy in a renovation or to show the construction sequence and space requirements on a construction site.

16 Digital Fabrication The use of models to facilitate the fabrication of construction materials or assemblies such as sheet metal fabrication, structural steel fabrication and pipe cutting. The models can also be used for prototyping with 3D printers as part of a design intent review process. Site Utilization Planning The model shall include permanent and temporary facilities on site for all of the phases of the construction process. The models shall be linked to the construction schedule (4D) to review space planning, site logistics, sequencing requirements, temporary works and safety.

17 3D Control and Planning A process that utilizes a model to layout project elements such as the position of walls using a total station with survey points preassigned in the model. The process of automating the control of equipment's movement and location such as using GPS coordinates to determine if proper excavation depth is reached. As-Built Modelling The process of preparing an accurate record of the physical conditions and assets of a project. The As-Built model should contain information relating to the architectural, structural, civil and MEP elements with links to operation, maintenance, and asset data. Additional information and data for equipment and space planning may be included.

19 Design Stage BIM PEP The lead consultant shall confirm that the architect, structural engineer and E&M engineers have agreed and committed to the BIM PEP. BIM PXP Construction Project Information Client BIM Requirements BIM Management BIM Process BIM Procedures Hardware & Software

20 Construction Stage BIM PEP The design consultants will hand over their BIM databases, models and data to the Contractor upon approval of the Construction Stage BIM. The consultants and contractor shall agree a process for incorporating design changes and revisions in the models after the handover date. BIM Management Production of the Building Information Models will be carried out by architects, engineers and contractors at different times during the phases of the project. A Professional BIM Manager should lead and support the BIM process

21 Roles & Responsibilities Roles & Responsibilities At the start of a project it is important to identify the roles and responsibilities of the consultant and contractor team members. Roles should be defined, agreed and maintained for each stage of a project. On smaller projects, one person may take on multiple roles and responsibilities
