Based on the provided information, the total value of the contract can be estimated as follows: The total bid price for Miller Bros is $4,071,639.18, for Telco, Inc. is $2,412,572.75, and for Wyoming Electric & Signal, Inc. is $2,542,270.00. Since the contract was awarded to all three vendors, the total contract value can be estimated as the sum of the three bid prices: $4,071,639.18 + $2,412,572.75 + $2,542,270.00 = $9,026,481.93. However, this is an overestimation as the actual contract value will depend on the specific items and quantities purchased. A more conservative estimate would be to use the lowest bid price, which is $2,412,572.75. Therefore, the estimated contract value is between $2,412,572.75 and $9,026,481.93.
