The article is devoted to the organizational aspect of solving the urgent problem of shortening the terms of implementation of investment and construction projects in modern conditions at the stage design The article examines the procedure for drawing up a design task by the customer at the stage of preparing tender documentation for construction objects in Ukraine, the financing of which is carried out with the involvement of budget funds, funds of state and communal enterprises, institutions and organizations, loans provided under state guarantees and defined and disadvantages The provisions of regulatory and technical documents regulating the procedure for drawing up a design assignment and its content have been reviewed. The list of problems that arise at the design and construction stage during the implementation of investment and construction projects due to the uncertainty and variability of data for project development, provided by the customer in the design task, is defined. The analysis of open sources of information regarding the procurement of design works showed that customers fill out the design task form, defined by the regulatory framework, on a formal basis, without actually expressing their real requirements for the future construction inspection. In "design and build" projects, the design task occupies a special place, since the contractor, on the basis of the customer's technical task, can determine not only the cost of the design work, but also the price of the construction work for which he is willing to perform it, while this price depends on technical and economic parameters of the building, which has not yet been designed, from the applied finishing materials, engineering systems, structural solutions, etc. An analysis of completed contracts for the purchase of construction works on "design and build" schemes was carried out, and they were divided into groups depending on the sufficiency of information in the design task. The foreign experience of organizing design works was analyzed, in particular, when implementing the "design and build" approach. It is proposed to improve the organization of the design process by separating the process of drawing up the design task into a separate procedure with a toolkit based on digital technologies, formulating the customer's requirements for design solutions and checking the validity of the customer's requirements. The feasibility of developing a toolkit based on digital technologies, which can be applied by the customer for drawing up a design task in investment and construction projects.
