Earthworks and Subgrade Stabilization

The contract titled Earthworks and Subgrade Stabilization requires comprehensive excavation, grading, and soil stabilization activities to prepare a subgrade foundation suitable for subsequent base and pavement layers. All work must meet a strict compaction standard of 95% Modified Proctor Density as defined by ASTM D1557, ensuring the subgrade achieves the requisite structural integrity and load-bearing capacity. The performance location is specified as Panama, with no additional state or zip information provided, and the work is intended to support infrastructure development under the auspices of the US Embassy in Panama City, managed through the International Boundary and Water Commission: US-Mexico. This is a subcontract opportunity with a NAICS code of 238990, indicating it falls under other heavy and civil engineering construction services. The solicitation was posted on July 28, 2026, with responses due by August 25, 2026, at 8:00 PM. While no specific point of contact or set-aside details are provided, the nature of the contract and its association with a US government overseas mission underscore its strategic importance and adherence to federal construction standards. Interested parties must ensure full compliance with geotechnical requirements, particularly regarding soil preparation and compaction, as failure to meet the 95% Modified Proctor specification may result in rejection of work or contractual non-compliance. The absence of agency office address details suggests direct performance at the site in Panama with logistical coordination handled through the embassy’s established infrastructure channels.
