Budget estimate

$150,000 – $300,000

The budget for this bid can be estimated based on the quantities and types of pipes required. The total length of pipes required is 10,000 LF, with 4,000 LF of 4-inch diameter HDPE, 1,000 LF of 4-inch diameter HDPE (perforated), 3,000 LF of 6-inch diameter HDPE, and 2,000 LF of 6-inch diameter HDPE (perforated). The cost of HDPE pipes can vary depending on the diameter, SDR, and other factors. Assuming an average cost of $10-20 per foot for 4-inch diameter HDPE and $15-30 per foot for 6-inch diameter HDPE, the total cost can be estimated to be around $150,000 to $300,000. However, this is a rough estimate and the actual cost may vary depending on the bidder's prices and other factors.
