The budget for this project can be estimated based on the line items. For Line 1, the bidder needs to provide a price per mile for 238.2 miles of three-pass road grading. The average cost of road grading can range from $5,000 to $20,000 per mile, depending on the location, road type, and other factors. Assuming an average cost of $10,000 per mile, the total cost for Line 1 would be approximately $2,382,000. For Line 2, the bidder needs to provide a per hour rate for 20 hours of hourly work. The average hourly rate for road construction workers can range from $50 to $100 per hour, depending on the location, job type, and other factors. Assuming an average hourly rate of $75, the total cost for Line 2 would be approximately $1,500. Based on these estimates, the total budget for this project could be around $2,383,500. However, this is a rough estimate and the actual budget may vary depending on the bidder's prices and the project's requirements. The factors that may influence the likely payment range include the bidder's experience, equipment, and labor costs, as well as the project's complexity, location, and timeline.
