A few years back, using three different programs for the areas:
A - Sales / Presentation
B - Building application / construction design
C – Timber construction / construction design
was absolutely normal in timber construction.
Various market participants realized that there was enormous potential for optimization from an economical point of view. The first result, DtH, was introduced in Rosenheim, Germany in 1999; a format that was supposed to enable the exchange of data between various timber construction programs. Some interface formats originated from this basic idea. Those can be found in Vi Plan today and allow a data transfer to SEMA, cadwork, bocad, Dietrichs and Weto. Simultaneously, a 2-system strategy was developed. The objective was to enable data exchange that makes reacquisition of existing information virtually obsolete.
It was inevitable to expand the sales program to the area of building application planning, due to its inherent calculation competence, as was to expand the timber construction programs in the area of construction design. The planning application and / or the sampling virtually predetermined reasonable hand-over times.
After the geometry transfer in 3D was implemented with various programs at different levels of integration and more and more companies started to implement these options, relatively quickly, the calculation surfaced as another relevant aspect. Many construction details, such as wall and ceiling structures are defined and their prices considered in the calculation. Re-entering these details in the designs would not have yielded an economic advantage compared to working with three systems.
And this is how the idea was born to access all the details of the calculation when transferring the 3D data of the design. This development was realized in different depths with SEMA, cadwork and Dietrichs. The following description references to the SEMA interface.
First, data couplings were created for the classic project data such as client, place of construction etc. The "mindset" of the systems, e.g. what is inside / outside, what is a floor and where does the term come from, were made translatable piece by piece. Next, options were created to define in which layer - for example when constructing the exterior walls - the geometry is to be read in the timber construction program. Once the implementation has been pursued with different companies, all participants realized quite soon that each company likes to have their very own structure and content of their master data.
For each company to maintain its own way of interpreting the master data - and this applies for Vi Plan AND Vi Kalk AND the timber construction program - the timber configurator was developed to serve as a translation level, which allows companies to have the data translated from A to B. For this purpose, we will give you a few examples:Example A
Different outer wall constructions are executed. For this, different master data sets exist in the timber construction program. The planning permission application is executed in the purchased standard wall structure, which can definitely be changed in the calculation, e.g. by another timber formwork, beam design or planking.Solution
: When transferring the exterior walls, the geometry of the configurator, which uses the settings of the calculation, is moved to the axis of the beam and transferred to the tinder construction program including the correct master data name. If it is a building partition wall, the configurator replaces the normal plaster base by a fire-resistant configuration within the master data record of the timber program – take notice that this is done without the need for a separate master data set.Example B
Both, closed ceilings as well as ceilings with exposed beams are used. No difference is intended in the preliminary planning, as this decision will be made later for financial reasons. In the calculation, the ceiling version can be controlled per floor and detailed specifications can be defined e.g. which stiffening plate is chosen. The outer walls are generally placed on the ceiling beams, the inner walls on the reinforcing/stiffening planking of the ceiling. The planking for closed ceilings measures 20mm and 35mm for exposed beams.Solution
: In the planning permission application, the ceiling is set to the strength of the framing. Everything else is set as/to planking or as part of the floor structure. During the transferal, the configurator checks, which ceiling version was sold and each inner wall, on which the ceiling it is positioned. This determines whether the configurator geometry cuts the bottom edge of the inner wall geometry by 20mm or 35mm. The corresponding correct values will arrive at the timber program.
Your added value
The economic value always depends on the used programs, the structure of the master data and the decisions to be taken on the data coupling. It will, however, be certainly well above what most people expect - IF you make the right decision.
