Analysis of the Impact of Input Data on the Planned Costs of Building Maintenance

Abstract

The aim of the article is to analyze the method of determining the maintenance costs of buildings based on the method proposed in Polish legal regulations. The analysis of the sensitivity of the method shows that the assumed number of product use cycles during the calculation period has the greatest impact, while the adopted warranty period has the lowest impact. A multi-functional building combining housing, office, service and commercial was analyzed in order to obtain a broader picture of the model’s operation. The results of the analyses allow us to conclude that despite the higher price of materials, the most durable solutions, which are the most expensive to purchase, turn out to be the most advantageous in the entire life cycle of the building. The method proposed in Polish law regulations has certain limitations. In order to level them, it was proposed to extend the method by using NPV (Net Present Value) for calculations and extending the life cycle of the building to 80 years.

Architectural, Civil, and Infrastructure Engineering in View of Sustainability: Editor’s Comment

“…Group (B) Economy-focuses on the life cycle, circular economy, and operating costs. Plebankiewicz & Gracki [6] deal with maintenance costs in the Total Life Cycle Costs. The analysis tool here is the Net Present Value method (NPV).…”

Selection of technological and organizational solutions for construction works with the use of a fuzzy relation of preferences

“…Some optimize the execution schedule in terms of time risk [8][9][10][11], others optimize the schedule taking into account the limitation of resource availability [12]. Noteworthy is also the cost approach, where the cost risk of the project is also analyzed [13][14][15][16][17]. In this respect, a developed mathematical tool in the field of probability theory, fuzzy sets theory [17,18] and multi-criteria decision making are used [19].…”
