Budget estimate

$100,000 – $500,000

The budget for this opportunity is difficult to estimate, as the Iowa DOT is seeking bids for the supply and delivery of Class A crushed stone or Class C gravel for shoulder aggregate to various locations in District 2. However, based on the quantities listed in the solicitation document, the total budget could be in the range of $100,000 to $500,000. This estimate is based on the assumption that the average price per ton of the material is around $50 to $100, and the total quantity of material required is around 10,000 to 50,000 tons. Factors that may influence the likely payment range include: • The number of bidders and the competitiveness of the bidding process • The prices quoted by bidders for the supply and delivery of the material • The quantities of material required by the Iowa DOT • The duration of the contract period
