2.2. UNDERSTANDING – FORMWORK Understanding, the building and job site requirements as well as the clients’ intention of the construction method, is one of the main subjects to discuss before talking about an optimized formwork solution. Different to the common procedure on standard projects, the construction method and the corresponding formwork solution for dam constructions shall be defined already in the design phase of a project in order to optimize the processes during execution phase. The optimized formwork solution can be influenced for example by the geology, the geometry of the structure, the construction method as well as the construction schedule (see figure 7). Vice versa an optimized formwork design can influence the geometry of the structure (e.g. increased block size resulting in less construction and block joints), improve the construction method and speed up the construction schedule resulting in increased productivity and ideally reduced construction costs. An optimized formwork solution means to meet the right balance between the influencers and the formwork or accordingly align the specifications on both sides in order to meet the project and client expectations and furthermore assure the demanded final quality of the dam structure.
