Quantity assessment method for the sustainability of a construction company

Abstract

Introduction. Professional construction customers (investors) often face the problem of selecting a reliable contractor, when they have to assess construction companies for potential involvement in their projects guided, among other things, by a directly non-measurable emergent indicator of sustainability (from now on referred to as sustainability of a construction company). The given problem is of particular concern as most construction companies are now financially unstable.
 Materials and methods. The article defines the sustainability of a construction company. It also evaluates the sustainability of a construction company indicator by a number of statistical estimate iterations. The study proposes an evaluation method for quantitative integrated synthetic aggregators of sustainability of a construction company and identifies several private indicators Xj characterizing a construction company’s stable condition.
 Results. The advantages of the proposed evaluation method for the sustainability of a construction company are as follows: a unified information basis (construction operations indicators) for the assessment of qualitative and quantitative integrated synthetic aggregators of sustainability. This method is based on unified evaluation indicators of construction operations: technical, technological, organizational, and economical. The proposed method has an advantage of the versatility of the resultant own and comparative assessments of the sustainability of construction companies, visual clarity of obtained results, and relative ease of calculation procedures.
 Conclusions. This study illustrates a procedure developed for evaluating quantitative indicators of the sustainability of a construction company. This procedure offers a high level of accuracy in determining the reasons contributing to the lower sustainability of a construction company and identifying symptoms indicative of loss of sustainability. An integral indicator is formed that assesses the stability of the construction company according to the results of statistical analysis and represents a weighted sum of the values of the initial indicators of construction operations and activities of the enterprise. In this way, businesses can assess both their own condition and the condition of proposed contractors.
