Application of project management tools in construction phases to optimize the impact on quality, cost, and time: A case study

Abstract

This work deals with the disturbed construction process, evaluated using the parameters cost, time, and quality. The aim is to transfer the actual situation of the disturbed construction process into a structured construction process. In this context, the possibility of data analysis and the associated creation of a resilient initial situation is demonstrated. One factor, time, is classified into a measurability with the possibilities of Gantt and Lean Construction Management. A representation of the monetary situation is the determination of additional costs. Here, the best case and worst case are presented and evaluated. The execution of the quality requires the comparison with the fictitious, planning quality defaults at project initiation and the now under consideration of the default costs and dates possible degree of fulfilment. The realization at the considered object has the following initial situation. Construction delay approx. 1 year, delta costs approx. 250 million euros, quality approaches were revised and partly reduced. This was the base for the creation of a schedule. The milestones from the Gantt schedule were incorporated into the system for the Lean Construction system. The monitoring between the milestones or intermediate goals was measured in the target-actual comparison.
