Description:
<jats:p>Abstract. The article describes a methodology for optimising the costs associated with managing the process of civil engineering construction during the design and implementation of the construction management plan (CMP). The general construction technology is determined by a sequence of partic-ular activities using construction equipment and qualified executive specialists. The costs of the work performed by technical and labour resources, together with the costs for enabling these works at the construction site, compose the total costs of construction companies. These costs are covered by the cost estimation documentation of a constructed facility. This article proposes an economic and mathe-matical model for optimising the volume of these costs during the development and implementation of CMP sections. The developed model is used for assessing the costs associated with constructing a residential building, considering various patterns of the used technical and labour resources. Conclu-sions on the dynamics of changes in the costs for this building are formulated, along with the effect of construction period on the volume of construction costs.</jats:p>
