An integrated design system with a quality by design approach
BIM (Building Information Modeling) is a method for the parametric and digital representation of a system’s physical and functional properties and is a design method that enables the integration, optimisation and updating of its constituent parts throughout the design life cycle. It can be applied perfectly in both revamping and greenfield projects, because it simplifies the integration of Facilities and Utilities by means of a three-dimensional and parametric model which allows a set of defining attributes, such as geometrical and physical characteristics, maintenance procedures, energy performance and electricity, heating and cooling consumption, to be recalled and modified at any time.
The benefits of BIM
Thanks to the benefits it offers in terms of design quality and integration, the BIM method is an essential requirement for projects applying for EU funding, as defined by the Public Procurement Directive (EUPPD) approved by the European Parliament.
Construction of a 3D model with an extremely high resemblance to the final structure.
Higher design quality standards from every point of view.
Reduction of subcontractors’ construction times and modifications.
Effective review of the project on the basis of the parameters defined.
Greater integration of the skills of the architects and the various teams.
The BIM method integrates 8 dimensions of the system into a single design model
All elements of the 2D design are used to produce a three-dimensional model of the entire system or building.
All 3D elements are linked to the planning activities in accordance with the Gantt Chart.
All 4D elements are linked to the relative resources to define the final costs and those of each phase of the project.
All the building’s systems are evaluated in terms of Energy Management, acquiring information about the factors that define the various phases of the building’s lifecycle.
The adoption of BIM and its ability to model databases of 3D items revolutionises many maintenance processes and allows integration of a building’s lifecycle.
OCCUPATIONAL SAFETY AND HEALTH
The use of 3rd and 4th dimension BIM modifies the management of H&S processes, aiding risk reduction and the coordination of activities.
How the BIM model is applied
1. INTEGRATED PROJECT DELIVERY
BIM is implemented thanks to a team of people, systems, structures and practices that come together to maximise efficiency during design and construction.
2. LEVEL OF DEVELOPMENT SPECIFICATIONS
LOD is a benchmark for defining the contents, accuracy and reliability of BIM at all design levels, to support the team and produce documentation.
