Â· I have been searching for Geotechnical Engineering books and resources that talk about the cost estimates for various projects. I have done the preliminary designs and calculated the quantities. All I need to do now is to survey the operations that are involved in the project to make sure I donâ€™t miss any operation or at least I have covered most of the operations. I am actually referring to sources and books concerning geotechnical investigations, construction, design, and construction monitoring and costs. Iâ€™m a geotechnical engineer and I know that this should be based on experience but I really want to know more.
