What information does the structural engineer need for the calculation?
Before one of our constructors can make a construction calculation of your roof structure, he needs two types of drawings:
- Original drawings of the building
- Drawing of the desired situation
Original drawings of the building
All these drawings are stored in the municipal archives. Here the construction drawings are especially important for the constructor. You can request these construction drawings, even if you are not yet the owner of the property. Would you rather have us request the original drawings for you? That is also possible, more information can be found in our quotation.
Drawing of the desired situation
Furthermore, a constructor needs information about the desired situation. A construction drawing of the desired situation makes it clear what your wishes are as a customer. For a roof structure that requires a permit, this drawing is in most cases made by the architect. For a permit-free renovation, these drawings may be less extensive. In these types of cases, we as a constructor can also draw the desired situation.
Install a roof structure and apply for an environmental permit
As is now known, it is mandatory to apply for an environmental permit before installing a roof structure. You can apply for an environmental permit via the municipality or online environmental counter. The procedure for applying for a permit takes on average between 8 and 14 weeks, so it is important that you apply for your permit on time. In many cases, the permit application for a roof structure is submitted by your architect. Based on these drawings, the municipality checks whether you meet the requirements of the building code, the zoning plan and the building regulations.
How far can I build up?
Local regulations apply per municipality to what type of roof structure is permitted. Therefore, take these regulations into account when designing and conduct research into the aesthetic requirements and zoning plan of your home. You can also leave this to your architect. Based on the research, you can determine what options there are for a structure for your home.
