Abstract This paper presents modern application of fire safety engineering (FSE) in the shaping of civil engineering development. Presented scientific achievements of FSE become tools used in typical modern engineering workflow. Experience gained through successful implementations of these solutions is then further crafted into prescriptive laws that shape future fire safety. This diffusion of knowledge is limited by law requirements themselves, technical limitations, and yet unresolved challenges that are still being worked on by the researchers in this field. This paper aims to present the achievements of the FSE discipline that may and should be used by civil engineers and other participants of the building process. Explanations given for the choices of fire safety engineers allow a better understanding of their gravity by representatives of other engineering branches. That way it is possible to build empathy between different engineering disciplines, which may significantly improve both the building design process and safety of the buildings itself. The chosen framework of this paper is Appendix A to EU Construction Products Regulation defining basic goals for a fire safe building, with a possible application of FSE given for each of these goals. The current framework of performance-based FSE is presented in relation to the Polish legal system, with recommendations on how to improve both FSE and civil engineering in the future.

Risk Cost

Reliability and safety for hardware in computer systems have been sufficiently studied in recent years. On the other hand, a safety-related system (SRS) for software has not been assured with the proper method of calculating the software safety integrity level (SIL) in the functional safety standards, which is currently determined only by the number of development methods applied to practical safety-related system (SRSs). In this paper, we discuss quantitative assessment for it by applying quantitative measures based on software reliability growth models (SRGMs) that have been widely and successfully applied to practical software quality management activities. Based on a nonhomogeneous Poisson process (NHPP), the plausible methods of calculating software SIL in the functional safety standard are proposed. Further, we discuss the quantitative method for assuring software SIL based on the optimal release policies with the test cost during testing-environment and the risk cost after the software products will be released.

Hydraulic Operation

Hydraulic power development may be divided into two groups, first, one in which mechanical and civil engineering developments combine to use natural forces for power production, and second, the phase of hydraulic power development which it is proposed to consider, namely that appertaining to mechanical production and automotive traction. Until recent times, no phase of engineering development has remained comparatively stationary for so long a period as that of power operation by hydraulic means. It is true that there has always been a field where the characteristics of hydraulic power were essential, but in the more recent drawing and stamping industries, hydraulic operation was unable to compete until developments in collateral fields removed all disadvantages. Prominent amongst the developments to this end, has been the introduction of the variable-delivery pump to each machine, as against the central pumping station. These self-contained units are available with a normal maximum pressure of 1,000 lb. per sq. in., but in certain cases no less than 5,000 lb. per sq. in. can be obtained.
