About us

Software for the construction industry

SOFTTECH is your source for construction-specific software. We have convinced many large and small companies to use SPIRIT in their daily work. Our focus is on easy CAD operation for the completion of planning through all design and construction phases of projects. Since 1985, we have been developing CAD software and AVA programs that support your overall business success. We have expanded our portfolio with additional BIM software and thanks to regular updates of our software you are future-proofed. The demands on our products are just as high as the demands on modern buildings and CAD tools are designed to assist with the quality of your work.

Our product portfolio comprises software that makes it easier for architects, planners, engineers, scaffolders and builders in the construction sector to work through the necessary construction documents with compatibility as well as intuitive and useful functions.


Architecture and Design

Building construction and presentation

BIM means that all programs work together. Start in SPIRIT with conceptual design and employ the same CAD program for the complete building process from execution to work planning. Your 2D or 3D building model can also serve as the basis for render-ings and visualisations in SketchUp Pro and SimLab. Working in 3D is much more time-consuming than drawing simple 2D plans – SPIRIT offers you the necessary flexibility because the software from SOFTTECH is continuously developed in 3D and 2D. In addi-tion the rendering software SimLab gives you an attractive and powerful acquisition tool for visualisations, animations and 3D PDF files.


Cost evaluation and quantity survey

Transfer quantities directly from your CAD to your contracting program and seamlessly trace your quantity take-off from AVANTI to your SPIRIT drawing – the easiest way to put BIM into practice. Avoid tedious and error-prone copying from and to Microsoft Excel© thanks to the optimized link between design and calculation when using AVAN-TI – the professional tool for graphical quantity take-off and cost estimation. Item lists will automatically be taken from databases and all data from the building model will directly be enhanced with cost estimations. Due to structured item lists you can evalu-ate and compare the cost calculations of potential contractors almost automatically. AVANTI is your contracting software for cost estimation and cost calculation accord-ing to DIN 276 and makes tendering, awarding and accounting so easy. You need quantity take-offs only and want to pay only for functions which you are really using? GRAVA enables you to calculate the scope of construction works from a digitized plan – simply, fast and according to DIN.

Cost and Controlling

BIM – Benefit from the smooth interaction of software solutions

SPIRIT is compatible with AVANTI (AVA software) as well as with all other BIM software solutions, such as SketchUp (Design Software) and facility(24) (CAFM software).

Transfer your SPIRIT building models and drawings quickly and easily to AVANTI; since the systems operate on the same database, the data can be fully processed. SPIRIT is also completely compatible with interfaces such as IFC, DWG, DXF, or GAEB CAFM with other "open BIM" software solutions. Thus, virtually loss-free data exchange is possible with all BIM software solutions. This is particularly im-portant since individual work phases are often performed by different employees, independent companies and in different software solutions.

Today I am a confident SPIRIT user, it still is my main CAD application, as an architect I do all of my technical documentation in SPIRIT (building permission drawings, construction documentation, detailing...). In public or government projects I use SPIRIT also to produce cost analysis lists of building elements. Models prepared in SPIRIT are easily exported to third part 3D applications for further visualization process.

Maria Demargne, Demargne Architect, London

I think Spirit is a great software, and when I started using it about 17 years ago it was one of the few softwares that would allow you to draw a 3D model and extract sections and plans with little effort. I have always been aware that Spirit can offer much more than what I use, including BIM and create various schedules. Spirit should have more recognition and be out there with the big players.
