Infrastructure refers to the basic physical and organizational structures and facilities needed for the operation of a society or enterprise. Infrastructure projects, therefore, refer to large-scale construction efforts that aim to develop or improve public works such as transportation systems, water supply networks, energy distribution systems, telecommunications networks, and other facilities necessary for modern living. These projects are typically funded by government agencies or private investors and can take years to complete due to their complexity and cost. They play a critical role in supporting economic growth, improving the quality of life, and enhancing the competitiveness of regions and nations.
