The Impact of the Additional Workload on the Productivity in Construction Projects

Additional works are not rare in construction projects. Their occurrence is often not anticipated on time. Practice usually only considers the direct impact on the organizational and technological aspect of them when planning the project, although it is known that they reduce the productivity and motivation as well. These hidden effects can reduce the dynamics of labour and thereby cause additional problems to managing the project. Moreover, constraints typically increase or are constant on projects through project phases and thus are completely maladjusted to the new conditions of increasing workload. Conducted research includes detail analysis and simulation of performance of 3 business residential building projects in Croatia, considering the relationship between the workload, time pressure and the work productivity. The technical, organizational and human component is considered. The paper proves the occurrence of productivity reduction in the case of additional work, no matter if the additional work is required or is consequence of prior poor performance. Based on the research results, the paper give the recommendation for reduced productivity compensation, which has direct impact on cost, time and resources and should be taken into account when deciding on additional work, if the project success is the main objective of project activities.
