BIM Use Process Copy

BIM is characterised by object-based modelling, the suite of tools extends beyond design modelling tools, such as Revit.

Some of the software tools are based on the project process (i.e. through briefing, design, analyse, plan, manage, review, cost and FM).

CDE solutions underpin all project processes.

BIM is not one single tool.

An IFC file is a model file created in the Industry Foundation Classes (IFC) format, which is an open file format used by Building Information Modeling (BIM) programs. It contains a model of a building or facility, including spatial elements, materials, and shapes.
The Design Review process includes systems and techniques to visualise and review Project Information Model.

This BIM Use includes further sub-activities such as technical design review and management visualization.

Visualization serves a critical function to ensure the design, construction and use of the project can be clearly reviewed for compliance with the standards and requirements set out by the Appointing Party.

The outcome of the review shall be used as a collaboration tool, in the form of 3D models, simulations and visual renders.

Additionally, the Contractor shall utilise BIM to review, examine and highlight safety and environmental risks.
‘Design Coordination’ describes the process of overlaying and coordinating the Project Information Model.

The BIM coordination model enables users to view how elements of architectural, structural, civil and MEP engineering systems are coordinated in a 3D space. The coordinated model is mainly used for carrying out clash detection.
To achieve a coordinated design, feasible for construction before the start of any construction activity.

Federation of Multidisciplinary Models, Spatial awareness.
Within a project, the designer and contractor are responsible for providing the systems required to coordinate models and conduct clash detection. The governance of clash detection is defined within the BIM Execution Plan (BEP).

The goal is to achieve a coordinated model feasible for construction before the start of any construction activity at the site.
Hard Clash – when two objects take up the same space, such as ducting running through a beam or when two different disciplines have modelled the same object.

Clearance Clash – Clearance may be for insulation or accessibility.
‘Engineering Analysis’ covers a range of additional specialist sub-activities such as structural, hydraulic modelling, traffic etc.

The Project Information Model will be used as the basis for conducting analyses and analytics (e.g. structural load analysis, pressure models or traffic simulations) to support better decision making and to predict and optimise project cost, schedule, value engineering, sustainability and safety of assets.

Depending on the analytics tool, the interface may be automatic/ semi-automatic or manual, but the Project Information Model data will be the input for analytics, and/ or the analytic results will be fed back to the Project Information Model.
Project Information Model should be intelligent models that have the ability to link individual elements to the material it represents.

This BIM Use includes additional sub-activities such as Bill of Quantity (BOQ) take-off and Bill of Material (BOM) creation.

The expected maturity of the measurements derived from the model must be aligned with the applied LOD (Level of Detail). The higher the Level of Detail provided by the model, the more mature/secure the measurements are.
‘Cost Management also referred to as 5D modelling, includes sub-activities such as cost forecasting, cost estimation and cost control. This BIM Use allows linking the model to project costs.

This BIM Use is relevant from the end of the design stage to the end of the construction stage.
Understanding the science behind moving earthing equipment is a main contributing factor.

Northumbria University has carried out extensive research and produced Use cases.

Earthmoving Cycle Components

Six Components

Primary Influencing Factors:

Load – Size & type of machines, Skill of the loading operator
Haul – Hauling distance, Haul road condition, gradients
Dump – Condition of the dumpsite, manoeuvrability
Return – Same as Haul
Spot – manoeuvrability, type of loading equipment
