Quality is a requirement of the 21st century, ranging from education to construction. Hence, this paper aims to treat in a theoretical but especially in an applied manner the set of concepts which lead to the achievement of quality in construction. The article is structured in five sections, followed by the resulting conclusions at the very end. The first section deals with the introductory elements of this article. The second section refers to the definition of the concept of quality in construction. The third section concerns the definition of the concept of planning in construction, as a necessity to reach the quality level required by the Romanian legislation. The fourth section deals with the elements of a database design for a construction project, its stages and the information that is processed. The fifth section refers to the case study that presents the elaboration of the project plan and the logical matrix of a project.

This article presents an original experimental and numerical approach to examining the pull-out behavior of fastening systems made of steel bars simultaneously embedded in both ends of concrete samples. This double-embedded configuration simulates a connection between the existing concrete structure and a new external exoskeleton, promoting seismic strengthening. Pull-out tests were performed across six specimen configurations combining different concrete strength classes in order to compare the adhesive solution against traditional monolithic cast-in rebar embedments. The adhesive-anchored bars achieved a peak pull-out force of ~28.6 kN, which is about 18% higher than with mixed anchorage (one end adhesive, one end cast-in). All specimens failed in concrete cracking and pull-out cone formation, with no steel bar yielding, indicating that failure was governed by concrete strength. Finite element simulations in ANSYS Explicit Dynamics were validated against these experiments, confirming the observed behavior and enabling the extension of our analysis to broader concrete strength ranges. Overall, the results demonstrate that double-ended adhesive anchorage significantly increases the connection’s load-bearing capacity and ductility compared to mixed configurations.

This article examines the financial management of a construction company over a period of nearly two decades (2005-2022). The impact of legislative modifications on small and medium-sized company (SMEs) within the Romanian construction industry was analyzed. The results of the data analysis reveal the susceptibility of a micro-entreprise (SME) in the construction sector to significant events during this period, indicating that both positive and negative effects were influenced and altered by about 50% . The study examines the impact of economic volatility and regulatory changes, including the 2009 global financial crisis and the COVID-19 pandemic, on the financial and development performance of the enterprise. The comparative analysis of construction sector statistics emphasizes the importance of regulatory stability for microenterprises within this domain. This offers valuable insights for the financial management of these enterprises and the development of small businesses during difficult economic conditions.

In the evolving field of construction, the use of advanced structural materials is becoming increasingly important. These innovative materials offer the potential to enhance structural strength, longevity and durability. The present study focuses on the analysis and comparison of two thermally insulating materials, specifically on Polyisocyanurate Foam (PIR) sandwich panels used in industrial construction.

Construction is very complex and affects both the environment and people’s lives and safety. At the same time, the construction sector is very dynamic and responds to the requirements and demands of customers, constantly adapting to engineering innovations and new technologies. In order to have safe buildings it is necessary to implement a quality system compatible with the quality system in force in the European Union. Thus, in accordance with the standards and regulations of the European Union, in Romania the activity in construction has continued, maintaining the tradition and the basic rules of the period before 1989, which have been updated and completed in order to meet the current legal requirements valid in the EU and the current challenges.

The changes occurred on the climate are a reality that produces changes within the socio-economic environment. Climate change is largely due to greenhouse gas emissions generated by human, domestic and economic activities. In this climate, the constructive solutions of buildings must take into account climate changes and meet new requirements. In this context, building materials must improve and correspond to the new paradigm so as to fulfill their basic role, namely: - creating an indoor climate corresponding to the hygienic-sanitary and thermal, - comfort requirements in residential and socio-cultural buildings, - ensuring the necessary indoor climate for carrying out economic activities reducing, as much as possible, the energy consumption for space heating.
