METHODS OF CONSTRUCTION DURATION ESTIMATION

This publication is devoted to topical issues of estimating the construction duration in time management in construction. The aim of the study is to analyze normative methods of estimating the construction duration, used at design and construction executive documentation developing. This aim is very important in terms of project management for selecting the most optimal methods of estimating the construction projects duration. Based on DSTU B A.3.1-22, SNiP 1.04.03-85 and DSTU B A.3.1-5, several principal methods of duration estimating were analyzed. Also, an assessment of the available methodologies accuracy and consistency was made. The study shows, that the techniques proposed in the normative literature have a number of significant drawbacks for their application in time management. The method of construction time estimating by averaged indicators, which used in Draft design, Feasibility Study, does not take into account a number of significant features of construction projects and performing organizations. Nevertheless, this technique can be used for a duration analysis in the initial stages of the project and business planning. The method of determining the construction duration, which based on the calendar plan, requires methodological refinement to the implementation of the "triple constraint" principle of project management. This principle allows to select the most optimal time, cost and work content and ensure the required quality of the project result with minimal resources outcomes. The obtained research results can be used by project managers when selecting methods for time management of investment and construction projects at various stages of project planning. The further research is possible to provide in the development of a method for estimating construction terms based both on the normative documents requirements and on modern project management methodology
