What is required from designers when building a house?
Building regulations in Finland define the designers which are to be mentioned in an application: the principle design officer and the architectural designer. Oftentimes the architect acts as the principle design officer and the architectural designer, however an architectural designer can also act as the principle design officer or an equivalent site manager. According to the general practice, in a planning permission application, the architectural designer, the HPAC (heating, plumbing, air-conditioning) design engineer, the water and sewer contractor, and ventilation design engineer are mentioned. More information on building permits for single-family houses is found from the local Building Control Department.
Other central designers and experts are the electrical engineers, responsible site manager, electrical contractors, water and sewer contractor, and ventilation design engineer. In addition to these specialists, an interior designer, a lighting designer, and a land surveyor can be used during the building project. If needed, more information on the designers and their duties can be found from the local Building Control Department. This department is an essential authority relative to a building project due to them being the managing authority.
What permits are required?
When building a single-family house a building permit is one requirement. This permit can be obtained from the local Building Control Department. In the permit application a qualified principle design officer is named (usually an architect), who ensures that, for example the application and plans including their attachments are in order. Other design engineers mentioned in the application are the architect, the HPAC contractor, and structural engineer. The qualification requirements of design engineers can differ depending on the region.
The Building Control Department of Tampere and other units of the city have, with the help of Rane complied extensive instructions of the essential stages and necessary measures of a building project. The instructions also cover issues concerning building permits. In addition to the advisors at Rane, the permit handlers at the Building Control Department also offer individual consulting.
What common construction defects should be avoided?
- flaws in the documentation
- unapproved special plans
- insufficient support of the roof truss
- errors in fire partitioning or other fire safety issues
- insufficiencies in the stiffening or total stiffening of structures
- flawed elevation between the ground and building floor
- insufficient weather guard
- insufficient control of moisture at the worksite
- the damage done to hinges created by heavy energy efficient windows and doors
If a house is fitted with energy efficient windows and doors the weight of them must be assessed when considering the strain on the hinges caused by them. Energy efficient windows and doors are heftier than traditional ones and the strain caused to the frames is greater. When washing the windows it is important to remember sufficient support to ensure the hinges are not damaged.
