The project requires the use of high-density polyethylene (HDPE) pipes with a diameter of 300mm for stormwater lines, ensuring durability and resistance to environmental factors. Construction must follow the specifications outlined in the tender documents, including trench dimensions, bedding, and backfilling procedures. The catch pits should be constructed using reinforced concrete, with dimensions conforming to standard design practices. All materials used must meet IS standards and be approved by the project engineer. The work sequence involves site clearance, excavation, pipe laying, road repair, and catch pit construction, followed by quality inspection and approval. Technical procedures must comply with safety and environmental norms to minimize impact and ensure longevity of the infrastructure.
