A quality advisory system has been developed for the early stages of mechanical engineering design, the aim of which is to provide quality advice in a variant design situation. In the domain of software engineering CBR has been applied to advise on which metrics are appropriate fora assessing the quality of the software currently under design. The system integrates CBR with concepts from quality function deployment (QFD) and incorporates a case library holding past software quality histories. CBR has been applied in support of conceptual design: to capture detailed design histories by monitoring designer actions, and thereby support design reuse through the evaluation of designs, through the provision of query, browsing and replay facilities. The resulting system is aimed to support the design of safety critical systems, by assisting in the construction of safety arguments, and cooperative design.

Therefore, the productivity of this activity must be measured and recorded to help the planners and estimators to improve the accuracy of the productivity estimate. But the obstacle is that there are several factors affecting the productivity. Moreover, the accuracy of estimating the productivity could be challenging when the effects of multiple factors are considered simultaneously. The aim of this research is to identify factors affecting productivity of (PRMC) using tower cranes within building projects, and to rank these factors according to their relative importance from a construction engineer's viewpoint. The analysis of 36 factors considered in a survey indicates that the main factors affecting productivity are: skip size, pouring size, availability of materials (RMC), building element, equipment efficiency, carpenter and formwork performance, tower crane capacity, and pouring level (height).
