Causes of Rework in Construction Projects in Ukraine

Abstract

The collapse of the Soviet Union was the cause of a significant decline in many economies of the newly created countries. However, many of them, including the Ukrainian economy, are slowly recovering. One of the largest branches of the economy in this country is construction, which, despite political turmoil, is constantly growing, especially in the private real estate development sector. Despite the fact that the construction market is constantly developing, it is limited by the costs of rework and alterations resulting from many reasons. The key negative effects of modifications to the results of the project are exceeding the budget and time of project implementation, dissatisfaction with the project team, violation of contractual requirements and lowering the quality of the final product. Therefore, the purpose of this article was to determine the reasons for the emergence of rework in the in Ukraine by analyzing the results of surveys conducted among construction enterprises.

Causes of Design Change Depending on Power Project-Types in Ghana

“…Furthermore, the experts' remarks suggest that this is a major problem in Ghana's construction industry as a whole, not just in the power sector. Quite different from past research, owner-related financial concerns are seen as a significant driver of design change, but they are not the major cause [25]. This may be attributed to differences in the discipline and region of research.…”

“…Design changes mainly originate from the owner side and are important causative factors to time and cost overruns [24]. In another study, poor working drawings and a lack of coordination among design documents were the leading causes of variation, also describing errors in design calculations and erroneous specification descriptions as two examples of design errors that resulted in variance [25]. Owner design changes during construction were identified as the most important cause generating delays in building projects in Egypt by the questioned owners, consultants, managers, engineers, and contractors, with a relative importance index value of 76.769%.…”

“…Several delay and cost overrun problems occur in projects mainly because of design changes which, according to the reviewed literature, account for the sizeable number of factors leading to delay and cost increase problems. Previous studies have elaborated on the effects of design changes on delay; in construction projects in Ukraine, the main cause of reworks is design change [25]. In a preliminary study on the causes of schedule delays and cost overruns of power projects in Nigeria, Ismaila et al [29] identified design change as an important cause for delays among three industry groupings, which included building construction, general power projects, and NPP projects.…”

Analysis of Rework Causes in Infrastructure Projects in Pulau Pinang

“…From the studies, it is found that rework causes can be divided to client related factors [9][10][11][12][13][14], design-related factor [10-11, 14, 16-17], subcontractor [9][10][11][18][19] and site management [6, 10-11, 14, 16, 19]. All listed causes were then used in the questionnaire survey in order to know the causes of rework in infrastructure project in Pulau Pinang.…”

“…However, a study conducted by Trach et al [13] stated that excessive workload and market conditions are external factors that contribute to the level of rework in the construction project. Restrictions on access for eligible skilled and knowledgeable subcontractors and employees cause increased defects and poor workmanship.…”
