ABSTRACT
Worldwide population growth is accelerating, which is driving up demand for essential items to meet demands. As time goes on, an increase in need has resulted in system degradation and deterioration because of an increase in global warming and a reduction in the amount of resources that are accessible. For humans to survive on Earth, water is a vital component. To properly collect, transmit, treat, store, distribute, and dispose of potable water and wastewater, a well-developed infrastructure is necessary. The water supply and sewage systems include fittings, transfer pumps, reservoirs, water channels, and piping systems. Systems for pipelines, reservoirs, water channels, transfer pumps, and fittings make up the water supply and sewage systems. Reinforced concrete, steel, ductile iron, asbestos cement, and reinforced concrete were used as materials for water delivery pipelines. Such systems require significant time and financial investment to build. The phenomenon of delays, which is recognized as one of the most common issues in the sector, has an impact on the building industry globally. This study investigates the impact of inflation on construction materials, particularly cement, used in water supply and sewerage infrastructure projects. Through a comprehensive survey of twelve construction industry stakeholders, the research identifies that inflation leads to significant cost overruns and project delays. These delays are primarily due to increased material costs, procurement delays, and conflicts among stakeholders. The study highlights that the rising prices of building materials reduce the purchasing power of clients and stakeholders, causing delays in material procurement and extending project timelines. To mitigate these effects, the research suggests promoting domestic purchases over imports and managing resources efficiently. The findings underscore the importance of considering inflation rates in project budgeting and recommend developing a budget estimation model that accounts for fluctuating material prices due to inflation.
