The article focuses on highlighting the role of life cycle costing (LCC) in the preparatory and implementation phase of residential projects. It involves the evaluation of several investment scenarios in the pre-investment phase, the choice between variants of the design of the entire building or its parts, and the choice of variants of structures and equipment with acceptable parameters. An innovative method of evaluating the life cycle of buildings is described in the article. This method was tested in selected residential projects realized by Skanska in the Czech Republic. Experience from construction practice shows that the choice of variants, constructions, or equipment of buildings only on the basis of the lowest acquisition costs (lowest bid prices) is wrong. The LCC calculation tool has been designed to model life cycle costs of individual variants of construction designs with different input parameters. It is possible to analyze the components or equipment that have the greatest impact on total life cycle costs. The article presents a tool that evaluates the long-term economic efficiency of the proposed residential buildings in terms of analysis of life cycle costs. The article will also expand the knowledge of the professional and general public about the importance of examining investment and operating costs already in the phase of construction preparation.
The paper describes the innovative methodology for the evaluation of the life cycle of buildings, which will be used in construction projects of Skanska, or other construction companies, in selecting the optimal solution from the point of view of construction engineering and LCC. The aim is to help LCC to be perceived by construction practice as a topic that needs to be addressed at the beginning of each construction project. The quantification of life cycle costs based on relevant input data on the technical parameters of the construction, structural elements and equipment, the time period of incurring the related costs should be an important basis for the decision of the investor, designer and future user of the building also with regard to environmental and social aspects, and in particular the long-term economic consequences.
This work deals with the application of cost management processes in the selection of real estate intended for housing. The paper focuses specifically on apartments in the Czech Republic, Prague. The selection of real estate is considered as a project, since this activity has all possible aspects of project management. A frequent mistake in choosing is to assess only the bid price in relation to the conditions and the location. Here the costs of real estate operation are solved, without the liquidation phase. However, future costs associated with the operation of the property always differ. This paper presents all possible costs associated with the use of a housing unit. Cost management procedures are planning, cost estimation, budgeting and cost control. By adapting the cost management rules to buy an apartment, the risk of inappropriate trade is reduced for most consumer units. It is possible to avoid unreasonable purchases and distortions of the real estate market not only in the Czech Republic but also in other locations. The aim of the work is to present costs that the buyer must calculate when choosing a suitable property and how to subsequently manage or control it.
This work deals with the analysis and assessment of the offer and actual prices of housing units in the town of Sedlcany. This city is located in the Central Bohemia region, in the Pribram district. The subject of the analysis is the monitored period of two years, from December 2020 to November 2022. The analysis is supported by data from the real estate portals Sreality.cz and Reas.cz, where the offer and actual prices are found, which are entered in the real estate cadastre in purchase contracts. Furthermore, the analysis is based on a local investigation and information from the public portal of the Czech Statistical Office, the Land Registry and the website of the city of Sedlcany, more specifically on their flood plan. Within the monitored period, there are a total of 46 bid advertisements at an average price of 53,619 CZK per 1 square meter. For actual prices, 53 price data are calculated with an average purchase price of CZK 47,884 per 1 square meter. The total average prices differ, but also their development, for which a regression function is always created. Due to the development of the number of offers and their prices, also due to the presence of new housing units among older properties, the reliability value of the offer price model is very low. A higher reliability value can be observed for real prices, where the impact of housing units from the newly completed construction of an apartment building can again be seen. The goal of the work is achieved through an overall analysis and assessment with the conclusions that new buildings have a large impact on prices. The subject of further research will be adding information to the overall context of the issue.
This paper shows how drones can help with construction inspection, which is currently costly in terms of the safety of workers and time. The paper depicts the use of drones to collect construction data with drone software that allows people to create 2D plans and 3D models. Moreover, the study explains how unmanned aerial vehicles, or UAVs, could improve job site safety and reduce material waste in the construction industry. Finally, this paper presents an exploratory study that identifies specific ways in which UAVs could improve safety at construction sites. Data collection of large construction projects uses surveyors' tape measures, laser rangefinders, total stations, and mapping software. However, these are time-consuming and costly methods that are impractical for measuring more significant amounts of space.In contrast, the use of UAVs would enable the next level of data collection to occur more efficiently. Specific examples using 3D software will demonstrate the potential applications within the construction industry and the challenges that limit their implementation into the industry. A UAV can monitor worksites and equipment to provide information to those responsible for operations, health, and safety in a timely fashion. The footage creates inspection reports from a distance, thus reducing pressure on-site and providing accurate reports faster. UAVs for inspections will eliminate or reduce the need for risk assessments, supply chain audits, and quality control audits during construction.
