Nowadays, the need for scientific and modernized engineering cost management has been increasingly prominent. Hence, this study compared the differences of the quantities’ terms, the management philosophy, the related institutions (or specifications), and other factors in engineering cost management between China and Germany accompanied by a case study for a warehouse building project in China. There are two main parts. Firstly, according to the literature research, the comparative analysis was conducted on the engineering cost-control mode, the list of bills of quantities, and other parameters between China and Germany. On the basis of this, the “differences” between China and Germany especially in the bidding process were further studied with the empirical analysis of engineering cases, which is a supplementary argument to the theoretical analysis. Finally, several related suggestions were put forward, including proposing a set of “universal” bills of quantities (which can be understood by Chinese enterprises and also accepted by foreign-funded enterprises), the establishment of the whole process, a dynamic and information-based project cost-management system, cultivation of talents with the advanced management concept, and the development of international engineering companies and project-management companies with core competitiveness. The conclusions are expected to provide some references for China’s construction industry to further expand the international market and to increase the influences in global markets.
