2. THE METHOD 2.1. UNDERSTANDING – CONCRETE Already in the project tendering and work preparation phase, the early strength development of individual concrete mixtures with different performance will be simulated with respective calibration and temperature assumptions. Necessarily, the intended concrete formulations can be re-adjusted. For this purpose, the early strength development of the intended concrete type is used as a performance indicator that can be planned, measured and controlled with Concremote (=real-time concrete monitoring system). Doka Concremote is used as a method to optimize the construction process and thus significantly increase productivity on the job site resulting in secured cycle time and optimized concrete costs in the execution phase (= ‘Concremote Value Engineering Methodology’, figure 1). Figure 1: The Concremote Value Engineering Methodology Ideally a construction company defines a concrete mix portfolio for example to consider ambient temperature changes (e.g. winter, summer, …) and other influences already before construction. In order to be able to create a portfolio of concrete mix designs a final design strength of specific structure member has to be defined by design engineers. To meet the requirements a wide set of scenarios for possible concrete mix designs are proposed for specific concrete structure (‘scenario gaming’, figure 2). 763
