Abstract: The work is devoted to the state and prospects for the development of BIM technologies in Ukraine. A review and analysis of domestic and foreign publications on the problem under study was carried out. The regulatory framework has been analyzed. It is argued that many problems of introducing building information modeling in the construction industry of foreign countries and, especially, Ukraine still require solutions. Several groups of specific problems associated with the implementation of BIM technologies are considered: in terms of design; in terms of construction; in terms of operation. The main activities for the successful implementation of BIM technologies in Ukraine are highlighted: combining best practices for the formation of regulations for BIM processes, taking into account international experience; a single data exchange unit for CAD integration and state coordination of this exchange; revision of existing budget standards; additional development of new cost estimates that take into account new technologies, new materials, machines and mechanisms; a unified coding system for enlarged units and structural elements of buildings in CAD systems with reference to estimate standards; unified classification of resources and services for construction in accordance with BIM technologies and harmonization with international standards; creation and maintenance of a database of regional prices for material resources; a unified open data format for transferring an information model of an object at different stages of design, construction, and operation into various software products; mandatory regulatory and financial support from the state.

Abstract: Construction projects are a combination of high complicated procedures that rarely go with the plan. The greatest dangers projects are the construction since it linked with an extraordinary amount of ambiguity and threat and that because of the business activities nature, procedures, and the outside surroundings. This paper investigates the problems during the pre-construction phase and the optimal solution for this problem by using to algorithm, partial swarm and Gravitational search algorithm. The results show that the construction problems have a severe effect on both time and cost and these problems must be treated immediately and this requires sophisticated techniques by using computer science. GSA and PSO are both used and show excellent results in solving these problems, the GSA algorithm shows better results in both the velocity is taken to find the solutions and in the accuracy. PSO is still a good technique in finding the solution and their future recommendation in making an expert system to find the solution more than one project and their interdependency.

Abstract: Micro, Small and Medium Enterprises (MSMEs) have been noted to play a significant role in promoting economic growth in less developed countries, developing and also in developed countries. Worldwide, the micro and small enterprises have been accepted as the engine of economic growth of any nation. Small and Medium Enterprises are the backbone of the economies, because it trigger employment, output, export, poverty alleviation, economic empowerment, economic development etc. in developed as well as in developing countries. It is more important to developing countries as the poverty and unemployment are burning problems. MSMEs have been playing a momentous role in overall economic development of a country like India where millions of people are unemployed or underemployed. Therefore, the growth of small sectors is essential for the growth in the GDP, employment generation, total manufacturing production and export. India, being one of the fastest growing economies of the world, needs to pay an honest attention for the utmost growth of MSMEs for its increased contribution in above areas.
