Abstract:
If extreme temperatures occur during the execution of civil engineering structures, technical measures become necessary to ensure the planned construction progress and the contractually agreed quality. These measures result from building material causes and normatively specified limit temperatures. For example, waterproofing work must not be carried out at temperatures below +5°C or in the presence of dew. The question of which limit temperatures apply, which technical measures can be taken and what additional costs are to be expected is answered in the diploma thesis.
In the second part of the thesis, the question is addressed as to how the aforementioned additional expenses can be taken into account in the supplementary design. The construction period is decisive here. In a regular construction process, the contractor bears the financial risk of extreme weather conditions. He can only be ordered to carry out special services that have not been taken into account in the contract, which gives rise to a claim for a supplement. In the event of a postponement of the construction period, the contractual basis for the claim and a concrete, construction-related description of the consequences of the hindrance are decisive. Weather-related additional expenses are the consequences of hindrances that occur as a result of the client's instructions or failure to cooperate. They can be taken into account in the design of the supplement.
