Budget estimate

$200,000 – $500,000

No contract value is disclosed in the amendment. Based on typical fire‑suppression retrofit projects for a historic building of this size (approximately 20,000‑30,000 sq ft), labor and material costs are likely in the low‑to‑mid six‑figure range. Assuming $150‑$250 per linear foot of pipe work, plus testing, insulation, and overhead, the total award could fall between $200,000 and $500,000. Larger contingencies for historic preservation requirements could push the high end upward.
