Methodology for Increasing the Efficiency of Design Work in Construction

In this article modern design systems for construction have been studied what allowed outlining their positive and negative sides. The analysis of one-stage and two-stage development of working documentation is carried out. The positive and negative sides of each system are revealed. The main problems of developing documentation in the pre-design and design stages are shown, recommendations are given for their elimination. The fundamental difference between one- and two-stage design is only in parallel or sequential development of design and working documentation.Using network diagrams and Gantt charts the ways of improving the quality and profitability of construction production through an improved methodology for organizing design work has been presented. The proposed design system is based on a change in the system of two-stage design and cooperation of construction entities. The proposed system allows reducing the time and cost of design work. Outsourcing the development stage of project documentation to contractors will allow getting a quality project with reduced construction time and cost.
