Deformations of foundations of windplant installation crane sites and their reasons

Abstract

Road and foundation deformations in modern Lithuanian construction are one of the most important problems. Constantly rising conflicts between customers and builders due to poor quality of foundations show that Lithuanian road builders do not ensure proper quality of work, do not perform the necessary road foundations and research, do not carry out continuous control of their work. One such example was the construction of the Pagegiai wind farm in 2014÷2015. Improperly installed road and crane installation foundations have forced the wind power plant to stop working, which resulted in enormous losses. Additional cluster engineering geological surveys that included a full range of field and laboratory work made it possible to identify the causes of poor quality work and to properly assess the properties of substrates and primers that are important for safe foundation operation.
