Value Analysis on the Utilization of High-Density Polyethylene (HDPE) Pipes as an Alternative to the Conventional Reinforced Concrete Pipes

Depending on their usage and structural capability, various materials are used for drainage systems. Because of its structural integrity and market availability, the reinforced concrete pipe has been widely used since the 1800s. However, with the introduction of plastic pipes and associated technology, it has become a formidable competitor to reinforced concrete pipes. The main impediment to using HDPE is the lack of knowledge about this technology, its unavailability in the local market, and the high freight and handling costs. This paper compares the cost-effectiveness of high-density polyethylene pipe versus conventional reinforced concrete pipe using value engineering analysis tools such as force field analysis and FAST diagram. Regarding maintenance costs over the product’s life, HDPE is more cost-effective than RCP. The lack of awareness about using HDPE pipes and their scarcity in the local market drives up their unit price in the short term. However, due to the ease of installation of HDPE over its RCP counterpart, there is a significant difference in labor costs. Our study found that HDPE pipes can save you about 5.88% in operation and maintenance costs compared to reinforced concrete pipes. This feature makes them an excellent choice for small-scale drainage systems like the ones frequently used in local areas. Our research suggests that using HDPE pipes as an alternative to reinforced concrete pipes in highway drainage design is bright and encourages more designers and engineers to consider them.
