Development of digital platforms for integrated control of the time, cost and quality of construction works

Abstract

The construction industry's transition to mandatory building information modeling has shifted construction supervision from selective documentary verification to continuous observation of three production parameters – time, cost and quality. The fragmentation of the software solutions used for this purpose generates a contradiction: digital tools are introduced along separate contours, while a management decision requires their joint interpretation, which is delayed under separate accounting. The aim of the work is to substantiate the architecture of a digital platform combining the three control contours into a single manageability indicator and to quantitatively assess the effect of such integration. The calculation is performed on the author's model of a portfolio of fourteen capital construction facilities using the chain substitution method and scenario modeling. The integrated manageability index rises from 0.627 to 0.841; the largest contribution to the increase comes from the time contour (0.089 out of 0.214), the smallest from the quality contour (0.051). The average lag in detecting a deviation is reduced from twenty-one to four days. The leading value of the time contour shows that manageability is achieved by synchronizing already collected data in a common environment rather than by increasing the number of autonomous control subsystems.
