The government intends to down-select up to three Companies to proceed to Step 2. Step 2-Pitches: Selected Companies will participate in pitch meetings. One company will be selected as the Construction Agent for award of the initial preconstruction services with a modification for construction award. AwardThe agreement will be awarded to the most qualified Construction Agent to provide preconstruction services and construction. Post-award Phase 1 of the CM@R includes Pre-construction services and Post-award Phase 2 includes the construction. The agreement will be Firm-Fixed-Price (FFP). The FFP for construction milestones will be agreed to as the design is finalized and funds are available. Key Qualifications that will be used for the a. Demonstrated experience with heavy civil construction in remote locations. (Experience specific to radar arrays, other OTHR systems, and work with Tribal observers will be given more consideration)b. Demonstrated experience in remote locations requiring establishing and maintaining man camps.c. Demonstrated experience with work in remote locations requiring a tight schedule.d. Demonstrated experience with work in remote locations requiring heavy logistical coordination.
