Construction Material Management Project

Managing construction materials is a critical process for ensuring quality and efficiency. By monitoring material usage, the company aims to maximize the quality of final outputs, minimize material waste, and reduce unnecessary construction debris. To achieve this, the company tracks material consumption and continuously establishes acceptable loss percentages for construction materials. This enables ongoing performance assessment and effective monthly planning.

Example Project: Wastewater Treatment (WWT) Pumping Station Construction (Reinforced concrete work scheduled to begin in August 2024) CH. Karnchang has established a maximum allowable loss rate for reinforcing steel at no more than 3%, in compliance with construction industry standards. Materials, including concrete and reinforcing steel, are subject to strict quality control and closely monitored. Clear quality standards are set, and monthly inspections are conducted to track actual usage. According to the materials management report (as of December 2024), it was found that

• Reinforcement Steel (Rebar): Implementation began in August 2024, with a loss rate of 1.05%, which is below the specified standard. The loss percentage has remained steady at approximately 1.07%, staying within a manageable range.
• Concrete: The monthly loss rate is recorded to compare actual usage with the calculated design quantity. In September 2024, the cumulative loss percentage reached 3.84%, which requires further review to ensure losses remain within acceptable limits.
