The contract value can be estimated based on the quantities and types of PPE items listed in the contract. However, without the unit prices of each item, it is difficult to provide an accurate estimate. Assuming an average cost of $10 per unit for nitrile gloves, $5 per unit for face shields, $10 per unit for N95 surgical face masks, $20 per unit for medical safety goggles, and $50 per unit for disposable coveralls, the total contract value could be estimated as follows: 1,000 units of nitrile gloves (small) x $10 per unit = $10,000 1,000 units of nitrile gloves (medium) x $10 per unit = $10,000 15,000 units of nitrile gloves (large) x $10 per unit = $150,000 14,000 units of nitrile gloves (x-large) x $10 per unit = $140,000 3,500 units of face shields x $5 per unit = $17,500 14,500 units of N95 surgical face masks x $10 per unit = $145,000 2,200 units of medical safety goggles x $20 per unit = $44,000 18,500 units of 3-ply face masks x $5 per unit = $92,500 1,000 units of disposable coveralls x $50 per unit = $50,000 6,000 units of surgical gowns x $20 per unit = $120,000 The estimated total contract value would be approximately $639,000. However, please note that this is a rough estimate and the actual contract value may vary based on the actual unit prices and other factors.
