The execution of work in hydro-engineering and land reclamation takes place in difficult conditions, because of the presence of water, the variety and changeability of conditions, the changes of the work-stands and work-fronts, the seasonal employment of the workers, the necessary of interference in the environment. This attributes result in appearing of different risk types. In this paper we present the identification and description of factors generating the unpunctuality of work execution. These factors are presented on a Ishikawa diagram. These are: management of investment process, organization and technology of work, machines, workers, building materials. These factors were divided in subfactors which are the sources of breach of contract of the time limit realization. These subfactors are: insufficiency of funds, absence of modern technologies, high work costs, seasonality and special requirements of work execution, necessity of nature protection in the water-course bed, incomplete dates of work quantity, absence of standard work time, planning using method with sequence work execution, planning of the work execution by deterministic methods, difficult selection of machine parameters, variety and changeability of work field, using of alternative schemes, inconvenient weather conditions, limited accessibility to the work-station, technical and organization breaks, tough and dangerous work conditions, deficiency ...
