Constructive design starts after the sales contract has been signed.
We have separated design into two stages:
The preparation of approval drawings, during which the designer places the architect’s idea in the element building system and performs the strength calculations. In order to start with the approval drawings, we only need architectural drawings from the client with the correct dimensions or to scale.
The preparation of production and installation drawings produces product drawings for the factory and installation drawings of the house set for the installation team. The client’s acceptance of the approval drawings is the prerequisite for the preparation of production and installation drawings.
During the design process, we follow European standards, while also considering national standards and provisions of the country of installation.
During the first stage, our designer prepares the approval drawings. The approval drawings set out the dimensions of the house, heights and all the important assemblies, some of which, like window, corner and eaves assemblies, also influence the building’s visual style. The approval drawings also contain load drawings for the foundation and its overall dimensions. We then submit the approval drawings to the client for review and signing. If the client wants to make alterations to the drawings, then these are done before the client signs the drawings. The review of the approval drawings is a stage where the client or their competent representative is obliged to check that the data in the project documentation is in accordance with national standards. Involving the client in the preparation of the project is an important measure for avoiding mistakes during the following design, production and installation works.
After the client has signed the approval drawings, the second stage of the design process can start, during which we prepare the production and installation drawings. If the client wants to make alterations during the preparation stage of the production and installation drawings, they must consider that redesigning will mean additional time spent and additional costs.
In the second phase, we prepare production drawings that include drawings for all the building elements and the required material specifications for all the materials needed for producing the elements.
A detailed production drawing which includes all the material layers used in the element as well as their locations guarantees that the construction and the dimensions of the element are correct. The use of production drawings also assures documented tracking for quality management purposes.
We send the production drawings directly to the factory and generally the client does not see them.
The installation drawings for element buildings show the installation order and the locations of the elements and their required connections with the foundation and to each other. The installation drawings also include detailed drawings, which have to be observed exactly to make the element building correspond to the architectural and approval drawings.
We give the installation drawings to the client as well as to the installation team.
We have established requirements for the production and assembly drawings that guarantee in the best way possible the flawless production and installation of a house set. If, for some reason, the materials or structure should change during the design process, the existing design cannot be used and the drawings have to be altered accordingly.
The volume and importance of engineering drawings for an element building is remarkably high. As a rule, the constructive design is done by our own designers or reliable partners. Our project manager coordinates and supervises the entire design process.
The design of wooden structures is based on Eurocode 5 standards, which apply throughout the entire European Union as well as in non-EU countries. Snow and wind load calculations are based on Eurocode 1 and 2 standards. In addition to that, we take into account national standards. When concluding the contract, our sales manager will specify with the client or their competent representative the requirements and standards associated with that particular building and the construction site, which the designer will then take into account when making static calculations.
Drawings that are based on the initial snow and wind loads for a particular location cannot be used for an otherwise identical building when the loads at that location differ from the ones used for the original building design.
