At the beginning of a planning phase of a project we need to understand two main subjects:  What is being built?  How is it being built? _Understanding - What is being built? The reason for the question is to analyze the basics of the dam construction and forming the foundation for our future work on the concrete structure (e.g. consultancy, value engineering, ….). Based on the project’s unique requirements (“what is being built”, figure 8) a tailor-made formwork solution in combination with an optimized construction method between all main structures (e.g. dams, power houses, inlets, outlets, draft tubes or scroll cases) shall be the target of the communication between ‘formwork solution provider’ and the ‘contractor’. Figure 8: Influencers for optimized formwork solution (what is being built?) Building: building designs often depend on the geology and surrounding job site conditions. Discussing the given settings in an early phase may result in simplifying the construction process with minor adjustments on the building designs and the pouring sequences. Geology: type and size of dam structure is influenced by the geology. Most of the time earth and rockwork is influencing the time schedule of an entire project. Keeping the earth and rockwork to a minimum and compensate the mismatch with the concrete structure might be a possibility to save costs and time. Formwork versatility and optimized construction sequences provide the options of financial and time savings. building? geology? site infra- structure? quality demand? minimize risks? 768
