Jitka Matějková — 2024-12-31

This article provides an in-depth analysis of recent legislative changes in the Czech Republic’s public procurement framework, focusing on the transition to the new Act on Public Procurement, which harmonizes national law with European Union directives. The new legislation introduces several key reforms aimed at modernizing and improving the procurement process. Among these, mandatory electronic communication stands out as a significant advancement, designed to streamline procedures and enhance accessibility for a wide range of stakeholders, including suppliers and contracting authorities. The Act further requires the disclosure of beneficial ownership information, representing a critical step toward fostering transparency and accountability in procurement transactions. Moreover, the integration of socially responsible procurement principles encourages public authorities to evaluate the social, environmental, and ethical impacts of their procurement decisions, thereby promoting sustainability and broader societal benefits. These reforms collectively aim to strengthen transparency, efficiency, and ethical standards in public procurement, ensuring more responsible use of public resources. This study offers valuable insights into the implications of these developments for various stakeholders in the public procurement ecosystem.

Enhancing BIM for more efficient energy performance calculations of buildings

Tomáš Funtík — 2024-12-31

Building Information Modeling (BIM) has the potential to revolutionize energy management by enabling stakeholders to analyze and optimize energy efficiency throughout the entire life cycle of a building—from initial design, through construction, to operation and maintenance (facility management). A BIM model serves as a foundational tool for decision-making processes, encompassing not only geometric data but also non-graphic information about the building's properties, systems, and environment. This rich data set facilitates various simulations and design optimizations, including those related to energy efficiency. For designers, BIM provides a powerful resource that aids in assessing measures by considering the characteristics of construction in relation to the future operation of the building. A significant advancement is the ability to conduct initial evaluations during the early stages of the project cycle, allowing for better-informed decisions and more effective planning right from the outset.

Overall, the integration of BIM into energy management processes underscores its critical role in promoting sustainability and operational efficiency in building projects.

Methodical Conflict among the Ways for Drying out of Historic Masonry

Alexander Németh — 2024-12-31

The purpose of this paper is to give a focus on evaluation of effectiveness of technologies aimed on remedy of unwanted moisture in masonry constructions of historic architectural heritage buildings standing under architectural heritage protection. There are many ways how to achieve the wonted state of the constructions, but some of them are quite invasive, some are not that much invasive and some of them are doubtful. The usual resistance of a group of officers of Heritage authorities to invasive technologies makes the practise complicated, as the, so called invasive technologies are usually the most effective. Officers usually welcome not that much invasive technologies and a special place in their understanding of this problem is held by the Method of Sequential Steps. This method is based on step by step introduced ways of solving of the problem, which should start with minimal interventions and continue towards more intervening interventions. This approach might be relatively sensitive to the structures, but it takes a lot of time and a success is not ensured.

Possibility of Using Building Structures Maintenance Planning

Martin Hanko — 2024-12-31

Maintenance of building structures in the use phase of a building is an important part of its life cycle. Planning the maintenance of buildings is not only about ensuring their technical condition, but also about efficient management of financial resources. A proactive approach to maintenance allows you to prevent costly emergency repairs, extend the lifetime of building structures, optimize energy consumption and preserve the value of the property. Regular maintenance helps in the early detection of potential problems, reduces the need for extensive repairs and keeps buildings energy efficient. The article highlights the importance of facility management, especially in the context of rising costs and economic challenges in Slovakia, while emphasizing the need for strategic planning to maintain efficiency and reduce operating costs and ensure sustainability. The article describes a proposal for a methodology that could be helpful for designers and investors when deciding on the material solution of a building. The methodology addresses the impact of the material solution on the future costs of maintenance and operation of the facility and suggests involving facility managers during the building design phase in order to optimize the costs of the operational phase of the life cycle.

Public Procurement of Construction Works: Significance, Challenges, and the Impact of VAT Changes on Procurement Efficiency

Simona Štastná — 2024-12-31

Public procurement plays a pivotal role in the functioning of government and public sector organizations, facilitating the acquisition of goods, services, and construction works essential for delivering public services and infrastructure development. In the context of construction, public procurement ensures the planning, funding, and execution of critical projects such as roads, bridges, schools, and hospitals, contributing to economic growth and societal well-being. However, the complexities inherent in public procurement processes often lead to significant challenges that can hinder efficiency and effectiveness. These challenges are particularly pronounced in the procurement of construction works, where issues such as cost overruns, delays, and quality control frequently arise due to the scale and complexity of projects.The impact of Value Added Tax (VAT) increases on public procurement is a multifaceted issue that has garnered significant attention in economic research. For construction projects, VAT changes can substantially affect project budgets, contractor pricing, and overall fiscal planning. A nuanced understanding of these dynamics is essential for developing procurement strategies that can adapt to the challenges posed by changing tax policies, ensuring that critical construction projects are delivered efficiently and within budget.

Calculation bases of finished works for budget item dimensions

Adam Hopocký — 2024-12-31

The preparation of an accurate and comprehensible bill of quantities is crucial for the financial management of construction projects. This process involves the analysis of project documentation, defining the technological process, and quantifying construction works, structures, and materials. The bill of quantities serves as a basis for the valuation of the construction and determination of the contract price. Its creation is time-consuming and requires expertise. In practice, we often encounter incomplete, inaccurate, or non-existent project documentation, which can lead to disputes and financial complications. Various methods can be used to verify the scope of completed works, including photographic documentation, 3D scanning, and direct measurement. Modern technologies enable efficient documentation of the building's condition and simplify the process of quantifying works. The accuracy and comprehensibility of the bill of quantities are essential for transparency and minimizing financial losses. This article gradually analyzes the bill of quantities and the possibilities for obtaining underlying values and measurements.
