The design of Kv. Järnvägsstationen 2 in Sundsvall, Sweden is groundbreaking, with the model predicting the future reality.
“If it is not in the model, then it doesn’t exist,” says Anders Lindblad of Sweco Systems, head of heating, ventilation and sanitation system designs. Anders and his colleagues know that they can rely on the virtual reality developed on the computer screens. Deviations from the model must be avoided at all costs, because they inevitably lead to problems, delays and increased costs during the build.
What would happen if the model is not followed? It can be compared with a car factory which suddenly discovers that a door does not fit and therefore begins to rebuild the car there on the assembly line. For the car industry, this is a completely unrealistic example. The goal of BIM is that such events should become similarly unrealistic within the construction industry.
Model begins in MagiCAD Room
Integrated designs help Sweco’s consultants to see into the future. By starting out with the architect’s plans and transferring the measurements to Magi- CAD Room, it is possible to create an accurate digital model of the building’s geometry – dimensions, floor plans, wall thicknesses, etc.. The model is then followed throughout the entire design process.
Sweco uses data from the MagiCAD Room model as input values in a climate simulation program. Positioning the building on the correct compass bearing and using climate data for Sundsvall, they can predict the building’s interior climate and energy consumption, the degree to which it is sealed against the elements and other parameters with excellent reliability. Even when the house is at the planning stage, it’s clear if it meets the requirements.
MagiCAD for all building services
Sweco’s designers produce both 2D and 3D drawings with MagiCAD for all HVAC and piping installations. Calculations of noise levels and pressure drops in the ventilation system are made directly in MagiCAD, removing the need for some external calculation programs.
Electrical installations are designed as 3D models in MagiCAD Electrical by consulting firm Teldako. The electrical installations are among the most advanced ever produced, with intelligent control modules and a router system where each fitting has a unique identity.
More effective logistics and installation
The designers use the MagiCAD models to compile bills of quantities and parts lists, enabling the flow of materials at the workplace to be directed to the right area, even to individual rooms. By reducing the time required to move materials around, additional time can be released for more efficient installation work. This is a decisive factor in enabling consultants and contractors to meet clients’ demands for faster, better and cheaper builds.
