TL;DR: It was found that productivity is higher when the robotic construction method is used for complex walls, indicating that it is possible to obtain significant economic benefit from the use of additive dfab to construct complex structures.
234 citations
TL;DR: An objective and data-driven review of the use of automation technologies in construction was done using text mining methods on publically available written documents, covering a wide range of relevant data including scientific publications and social media.
124 citations
TL;DR: In this paper, a review of empirical, analytical and numerical models to predict the time to cracking due to corrosion of reinforcing bars in reinforced concrete structures is presented. But, it was observed that the majority of the investigated models were only capable of adequately predicting the time-to-cracking for the experiments to which they were fitted.
108 citations
TL;DR: It is shown that the proposed methodology can be used to develop models to estimate the occurrence of road accidents for any road network provided that the required data are available.

TL;DR: In this paper, an alternative approach is suggested to take into consideration the physical phenomena underlying element deterioration, which is applied to chloride-induced corrosion of steel reinforcement, by far the most common deterioration mechanism in Switzerland.
Abstract: Condition assessment in the Swiss bridge management system (KUBA-MS) is performed on the element level. Five condition states are defined based on visual appearance. In order to forecast the condition states of any given element at any given time a relationship must be established between the element age and its condition state. This relationship, which describes the condition evolution, can be obtained empirically from statistical analysis of pairs of consecutive condition assessments (inspections). Markov chains are used in KUBA-MS to represent condition evolution and the transition probabilities are determined using regression analysis of pairs of inspections. Unfortunately there are almost no inspection data for the worst and second worst condition states. The forecasts made using Markov chains are therefore not always reliable. In this paper an alternative approach is suggested, which takes into consideration the physical phenomena underlying element deterioration. This alternative approach is applied to chloride-induced corrosion of steel reinforcement, by far the most common deterioration mechanism in Switzerland. The chloride-induced corrosion is modeled mathematically and numerical simulations of the condition evolution for different values of model parameters are performed. The simulation results have been mapped to condition states as defined in KUBA-MS and Markov transition matrices have been calibrated to fit simulation results.
