The budget for this project can be estimated based on the scope of work, which includes the installation of fencing infrastructure, custom gates, access control hardware, and system integration. Assuming an average cost of $50 per linear foot for the fencing infrastructure, the total cost for the fencing would be around $150,000 (assuming 3,000 linear feet of fencing). The cost of custom gates can range from $5,000 to $20,000 per gate, depending on the design and materials used. For four gates, the total cost would be around $40,000 to $80,000. The cost of access control hardware, including barrier arms and card reader pedestals, can range from $10,000 to $30,000. The cost of system integration, including labor and materials, can range from $20,000 to $50,000. Based on these estimates, the total budget for the project could be around $250,000 to $500,000. However, this is a rough estimate and the actual budget may vary depending on the vendor's pricing and the complexity of the project.
