Bim Uses Definitions - BIM NEW ZEALAND

[1]

The applicability of BIM (as methodology objectives or opportunities) is detailed in Appendix D Application of Bim Definitions - The 2019 New Zealand BIM Handbook [2]. The document covers 22 distinct applications broadly described. Each item is provided with a process description, potential values, required resources and competencies of the BIM team, and procurement notes. BIM applications are defined for:

Cited Online Document

• Modeling of existing conditions
• Cost estimation (5D costing)
• Phase planning (4D modeling)
• Spatial programming
• Site analysis
• Design review
• Create projects
• Engineering analysis (lighting, energy, mechanics, etc.)
• Structural analysis
• Energy analysis of the facility
• Sustainable development
• Code validation
• 3D coordination
• Planning of land use
• Structural system design (virtual mockup)
• Digital production
• 3D control and planning (digital system)
• Modeling of records
• Asset management
• Schedule of (preventive) maintenance of buildings
• Building systems analysis
• Space management and space tracking

Each of the above-mentioned items has its own specification, below are three representative items:

PROJECT CREATION: The process by which project creation and audit and analysis software is used to develop a building information model based on criteria important to the building design or specified in the MEA schedule. Design tools are the first step towards BIM and combine the 3D model with a powerful database of properties, quantities, methodologies, costs and schedules;

Potential value • Transparent design to all stakeholders • Better control of the design, costs and schedule • Efficient project visualization • True collaboration between project stakeholders and BIM users • Better quality control and assurance;

Resources required • Project development software and / or project analysis software;

Required team competences • Ability to create and develop a BIM model • Knowledge of construction methodology • Design and construction experience;

Procurement Notes • Define in MEA the expected level of detail required for the design elements at each stage and by whom;

SUSTAINABILITY: The process by which a BIM project is assessed against NZGBC Green Star, NABERS NZ or other sustainable criteria. BIM enables more sustainable practices in all phases of a facility's life, including planning, design, construction and operation. The use of BIM technology facilitates more sustainable design techniques by capturing and incorporating key data into the decision-making process, thus making it possible to compare the sustainability profiles of different building / system designs. It also enables complex analysis of energy and material consumption, facilitates more efficient coordination of supply chains, and reduces the need for rework and subsequent waste. Applying sustainable features to a project in the planning and early design stages is more effective (the possibility of influencing the project) and efficient (decision cost and scheduling). This end-to-end process creates an integrated building design philosophy that aims to involve all team members from the very beginning of the project to capture valuable insights. This integration may require contract integration at the planning stage. In addition to achieving lasting goals, applying for NZGBC certification requires the submission of specific calculations, documentation and verification. Energy simulation, calculations and documentation can be performed in an inclusive environment when responsibilities are well defined and clearly segregated.

Potential value • Facilitate interaction, collaboration and coordination of team members early in the design process • Enable early and reliable evaluation of design alternatives • Early availability of critical information helps to efficiently resolve cost issues and schedule conflicts • Shorten the design process by facilitating early design decisions, which results in cost and time savings • Improved project quality • Reduce documentation workload after design and accelerate certification when parallel calculations are used for verification • Reduction of facility operating costs through better energy management resulting from optimized building performance • Increased emphasis on environmentally friendly design and sustainable • Assisting the design team with potential future changes throughout the facility's lifecycle;

Resources required • Project development software;

Required team competences • Ability to create and view a 3D model • Knowledge of current NZGBC Green Star credit information  / NABERS NZ • Ability to organize and manage a database;

3D COORDINATION: Process used throughout the coordination process to identify geometry conflicts in a BIM model that can cause problems on site. This process can be completed using collision avoidance software that will automate the manual conflict checking process. The goal of 3D coordination is to eliminate any serious system conflicts prior to installation.

Potential value • Coordination of the construction project using the model • Reduction and elimination of on-site conflicts that significantly reduce RFI compared to other methods • Visualize the construction • Increase productivity • Reduce construction costs with potentially fewer variants • Reduce the number of on-site corrections • Reduce time construction • Increase on-site productivity • More accurate as-built drawings;

Resources required • Design development software • Model review application • Collision detection software;

Required team competences • Ability to deal with people and design challenges • Ability to manipulate, navigate and view the 3D model • Ability to run clash detection software • Knowledge of BIM model applications for facility updates • Knowledge of building systems;

Procurement Considerations • Define BIM briefly the minimum number of formal 3D coordination reviews • Define in a BIM brief the responsible party (ie Lead Consultant, Architect, third party) • Define short expected workflows or processes (if applicable) in BIM;

Over the past five years, the BIM Acceleration Committee in conjunction with EBOSS has been collecting data on usage levels for each of the BIM applications listed above. Data was taken from an industry control group of small and large pages covering all stages of the cycle.
