The estimated magnitude of construction is between $1,000,000.00 and $5,000,000.00. All work will be performed within Cells 1, 3, 4, and 5 of Poplar Island, a remote location accessible only by boat. The Contractor shall provide all necessary labor, equipment, materials, and transportation to perform the construction. The anticipated period of performance is approximately 120 calendar days.
