Analysis of the impact of the global crisis in 2021–2024 on the development time of multifamily blocks

The study describes the timeline of a construction project comprising six residential buildings, green spaces, and a playground. The project was carried out in the Warsaw area between 2022 and 2024. The investment was undertaken following significant events such as the COVID-19 pandemic, rising inflation, and the armed conflict in Ukraine. The study focuses on the analysis of selected phases of construction work performed as part of the investment described. The specific tasks highlighted include the installation of window joinery, the construction of internal masonry walls, the installation of partitions and balcony railings, as well as the delivery and installation of lifts. Additionally, general data on the work progress, construction schedule, and entries from the construction logbook referring to the specific completion dates of various stages were examined. Based on the provided data, an analysis was conducted to compare the time required to complete individual construction tasks against the schedule established during the project planning phase. The text addresses the challenges of meeting deadlines in large construction projects, where the technology used, the number of personnel employed, and the scale of the investment contribute to the extension of the construction process by the contractor.
