Existing conditions (subbase) require assessment before proceeding. FEATURE OF WORK; Taxiway G (Golf) Construction SPECIFICATION SECTION: S-140; “Site Demolition”, section 140-2.5 “Compaction of Existing Base and Subgrade”, P-152; “Excavation, Subgrade and Embankment”, and P- 154; “Subbase Course”. INFORMATION REQUESTED: Requesting ICE-Engineer to address and advise how to proceed ASAP. Reference: Approved for Construction (AFC) Plans: Sheet C2.3. Specifications: S-140; “Site Demolition”, section 140-2.5 “Compaction of Existing Base and Subgrade”, P-152; “Excavation, Subgrade and Embankment”, and P-154; “Subbase Course”. Requesting the following Information: During Phase 2 construction (demolition activities, 12/8/25) base rock was removed, revealing subbase. (Location is the Northwest radius at the Taxiway G and Taxiway B tie-in area.) Contractor encountered existing conditions of subbase different than expected, causing a STOP in WORK (questioning attitude prompted by contractor). Existing conditions as follows: Subbase of 8-12 inches of gray sand with (undetermined amount; 1-3 feet possible) sub-layer of “muck” (decomposed organics/spongy peatmoss layer at water table). Ground unstable, “pumping and moving” under equipment load. RFI 0004 was prompted by ICE-Engineers to begin the process of determination regarding how to proceed with demolition and construction activities for Phase 2. We appreciate your prompt response/acknowledgement of this RFI, as this clarification/correction is essential for maintaining construction alignment with project specifications. CONTRACTOR’S RECOMMENDATION: RFI response. Additional time and or materials possible. Please advise. Thank you!

Excavation of Unsuitable Materials; Excavate all unsuitable subbase and underlying muck to a depth of 2.75 feet below the proposed finished grade to remove all unstable, pumping material. 2. Placement of Replacement P-219 Material (Subbase Replacement); Backfill the excavation with P-219 crushed aggregate base material placed in two (2) compacted lifts of 12 inches each. Each lift shall be moisture-conditioned, compacted, and proofrolled in accordance with the specifications. Field density acceptance is required on each lift to achieve in place dry density at least 100% of the standard proctor ASTM D698) max. dry density. 3. Placement of Final 6-Inch Base Layer: After acceptance of the two 12-inch lifts, place the final 6-inch P-219 base course per project plans and specifications. Compact and test to meet all specified requirements. 4. Measurement of Repair Area; The RPR will measure and quantify the limits of excavation and replacement for documentation and payment purposes. 5. Time Considerations; As the unsuitable subbase prevented proofrolling and halted construction activities, the Contractor may request additional contract time as needed, in accordance with the procedures outlined in the contract documents. Any requested time extension shall include supporting justification and requires owner's approval. I.C.E.
