Offer preparation has always been a specific part of a building process which has significant impact on company business. Due to the fact that income greatly depends on offer’s precision and the balance between planned costs, both direct and overheads, and wished profit, it is necessary to prepare a precise offer within required time and available resources which are always insufficient. The paper presents a research of precision that can be achieved while using artificial intelligence for estimation of cost and duration in construction projects. Both artificial neural networks (ANNs) and support vector machines (SVM) are analysed and compared. The best SVM has shown higher precision, when estimating costs, with mean absolute percentage error (MAPE) of 7.06% compared to the most precise ANNs which has achieved precision of 25.38%. Estimation of works duration has proved to be more difficult. The best MAPEs were 22.77% and 26.26% for SVM and ANN, respectively.

The awareness of positive influences of outdoor environment on patients' healing process has long been present in hospital architecture. Despite the fact that economic factors had the greatest impact on hospital design during the past century, which caused a neglect of possible restorative benefits of hospital surroundings, recently developed and integrated healthcare systems are more focused on patients' needs regarding the effects of treatments and services on their satisfaction. With the aim to reduce costs of medical therapies without sacrificing their quality, this new approach resulted in a substantial shift in planning and designing of both indoor and outdoor hospital spaces. This paper presents an analysis of various aspects that need to be taken into account while planning of hospital outdoor spaces. It proposes a list of design considerations that may contribute to achieving a healing environment with positive effects on patients' well-being and outcomes of their medical treatments, while simultaneously raising the overall hospital's efficiency. Having in mind specific organizational structure and functional flows that an institution of this type comprises, these considerations are determined, preconditioned and set up to meet strictly defined norms, regulations and criteria. The purpose of this research is to examine which elements and features and to what extent may assist in generating a supportive, inviting, secure and non-threatening atmosphere of the outdoor hospital surroundings that discharges negative reminiscences, experiences or assumptions on how unpleasant the stay in a hospital may be

The research presented in this paper addresses the process of architectural design and particularly the role of graphic representations in that process. The present paper gives a brief state-of-the-art in the fields of design process and drawings that are involved in that process, but also tries to emphasize the importance of process drawings in the context of the architectural studio which represents the basic framework for acquiring the skills of architectural design. The findings of this study indicate that different types of drawings play a key role in the design process and that the creation of these graphic representations can be identified with the thinking process in architecture.
