All about builders

The Builder is Construction Law The legally and economically responsible Client in the implementation of Building project. As a builder is someone who can prepare their own behalf or for the account of others or their own building projects or to prepare or execute or run can be. He can be both a natural person and a legal person be.

The developer has to prepare, monitor and execute a construction project requiring approval or notification one author of draft and to appoint a contractor, so depending on local legal requirements. The builder is also responsible for the public service regulations necessary applications, documents and notices to building control authority. He may delegate these tasks to the draft author.

Are the persons appointed by the client for their duties after expertise and experience is not suitable, then the building control authority before and during construction may require that unsuitable officers replaced by a suitable or appropriate expert can be used. The building control construction work can be set, are ordered to appropriate officers or experts.

Changes the client, and then notify the new owner of the building control authority in writing immediately. Furthermore, for the builders Security and Traffic Safety on their Site responsible and bear responsibility if third parties were appointed to handle and oversee the building project.

Live 20 years longer thanks to healthy diet

That healthy eating is important for a healthy life and a healthy body that is not a Gehmeinis. Now Ernärhungswissenschaftler discovered in an investigation: Who eats properly, can hope to be up to age 20 years.

Much fat, sugar and much salt: Today's diet is often so unhealthy that it not only makes fat. Because according to German Nutrition Society (DGE) in Germany are "food-related illnesses for 68 percent, more than two-thirds of the deaths." Go Of the approximately 850,000 deaths annually in the country more than 550,000, at least in part on the account of the diet. 

In reverse, a healthy diet can obviously extend the life. "Those who can properly nourished, may hope for a further bonus of up to 20 years," the Jena nutritionist Michael Ristow says to the world. Eating plenty of fruits and vegetables, lots of fish and little meat included in the opinion of Ristow to the diet. This red meat is particularly unfavorable. Ristow cautioning against compensate for the vitamin requirements with tablets. No amount of high-dose vitamin capsule can replace an apple with its hundreds of individual substances.

The non-ventilated flat roof (warm roof)

Basically a non-ventilated flat roof of a support structure for example consists of reinforced concrete, wood or steel trapezoidal profiles, which connect to the insulation and the roof skin flush. If you look more closely at the structure again, we see how many layers there is really a hot roof.

•    To get the required angle of the roof is applied in concrete structures (ceiling of the building) a concrete layer gradient (slope screed). This is obviously connected with an unwanted weight gain. They used either unreinforced normal weight concrete or lightweight concrete. However, there are disparities insulation panels that can take over this function. For wood and trapezoidal sheet roof structures may be contacted by the slope without great technical effort.

•    The supporting structure, in addition to the space separating the tasks still function to absorb the expense and pay off as well as to ensure sound and fire protection. Supporting structures made of reinforced concrete and profile sheets available on their surface a primer for bitumen emulsion or bitumen solution. The primer is applied to improve the adhesion of the adhesives. In addition, it binds the remaining dust and has a water repellent effect.

•    The following is a compensation or separation layer. Its task is to separate incompatible materials and also serves as a sliding layer. The separating layer may for example consist of perforated glass fleece bitumen or bitumen roof membranes with an insert made of aluminium or copper foil.

•    Recommended for the subsequent vapour barrier or vapour barrier is a PE film or roofing sheets, depending on the requirement of different support insert.
This vapour retarder / vapour barrier is to retard or prevent the diffusion of water vapour in the insulation and the seal or under.

•    For example, thermal insulation are mineral wool, polystyrene PS, EPS expanded polystyrene, extruded polystyrene XPS foam and glass. For sparkling glass on concrete structures is a vapour barrier is not necessary because it is moisture-resistant high pressure loads and after the installation. As already mentioned, the insulating layer can serve also to produce the required minimum gap.

•    The task of the vapour pressure equalization layer to local vapour pressure generated when heated or immigrant trapped moisture to distribute, and to relax by. It also allows relative movement between the roofing (roofing) and thermal insulation. The compensation layer usually has a multilayer structure. For example, as materials are perforated glass fleece bitumen or bitumen roof membranes with an insert made of aluminium or copper foil.

•    To get the waterproof construction, there are roughly two ways: the structure and the bituminous film structure. At least two layers are bituminous constructions, while foil seals are generally carried out in one layer.

•    A gravel layer with a thickness of 5 to 10 cm is used to protect against direct sunlight, wind suction and mechanical damage. Please refer to the paragraph "Gravel on the roof - yes or no?" But also as a surface protection plate covering, roofs, slate and ceramic chips using interference.
