The Statement of Objectives (SOO) outlines the need for a qualified contractor to perform in-place soils and concrete testing and analysis at two locations within Gwangju Air Base, Republic of Korea. This critical assessment supports future pre-engineered building construction by evaluating the suitability and integrity of existing subgrade and concrete. The scope includes sieve analysis, theoretical maximum dry density analysis, soil sample extraction and cataloging, detailed reporting, and coordination with government representatives for both areas. Additionally, concrete core samples will be collected and tested for compressive strength in Area 1. The project's completion date is set for October 31, 2025. Deliverables include a field sampling plan, certified laboratory test results, and a final soil analysis report with conclusions and recommendations.

This Statement of Objectives (SOO) outlines the requirement for a qualified contractor to perform in-place soils testing and analysis for a one-mile stretch of road at Osan Air Base, Republic of Korea. The primary objective is to assess the suitability and integrity of the existing subgrade for future road construction or rehabilitation. The scope of work includes comprehensive field and laboratory testing, such as sieve analysis, theoretical maximum dry density analysis (e.g., Modified or Standard Proctor Test), and the extraction and cataloging of soil samples. The contractor must provide detailed reports, including data tables, graphs, and professional interpretations, and coordinate closely with government representatives. The project is expected to be completed by October 31, 2025. Deliverables include a field sampling plan, certified laboratory test results, and a final soil analysis report with conclusions and recommendations.
