The contract value is not explicitly stated in the document. However, based on the scope of work, which includes new construction, modernization, maintenance, and repair of elevators, escalators, walkways, and lifts, the contract value could be substantial. Assuming an average annual expenditure of $100,000 to $500,000 for maintenance and repair services, and considering the contract duration of 4 years, the total contract value could range from $400,000 to $2,000,000. Additionally, the contract may include costs for new construction and modernization, which could add to the overall value. Therefore, a rough estimate of the contract value could be around $1,000,000 to $5,000,000.
