Estimates are midpoint selections from provided ranges.

[#27] Emergency response & contingency fund (reserve for rapid escalation, breach repairs, emergency evacuations); large one-time recommended reserve (midpoint of range).

[#21] Laboratory instrumentation (GC-MS, ICP-MS, isotopic analyzers, water/gas analyzers) for environmental/material analysis; estimate reflects instrumentation purchase (service contracts handled in recurring).

[#2, #16, #20, #23] Includes exhaust venting and air-scrubbing system installation, surveillance and sensor suite install (CCTV/IR/thermal/tamper sensors), high-resolution imaging/digitization equipment, and mapping/remote inspection gear (LiDAR/drones/borescopes).

[#26] Initial memetic/cognitohazard mitigation equipment and training (filtered displays, viewing protocols, memeticist consult); midpoint of provided initial range.

[#29] Initial vetting/background checks and baseline security training for ~20 personnel (~$2,000/person × 20).

[#6] Capital spare parts & deep maintenance event for exhaust scrubbers/catalytic units; one large replacement event estimate (every 3–7 years) included here as a one-time major replacement.

[#30] UPS/generator install to provide independent power for monitoring, ventilation, and alarms (midpoint of range).

[#32] Initial secure server/storage/encryption infrastructure and colocation setup (one-time purchase/retainer).

[#7] Acquisition (if required), physical modifications (welding of side doors, partition), and cover-style documentation; mid-range estimate assumes used van purchase and modifications.

[#25] Secure archival locker / climate-controlled storage unit purchase for SCP-5472-3 (unit cost). Small annual maintenance/power costs are recurring.

[#11, #18, #19] Salaries and benefits for dedicated security guard complement (8 guards) and research team (lead researcher + ~3 researchers) plus a full-time linguist/analyst; sum of midpoint salary estimates from notes.

[#15] Medical staff time, psychiatric care, medication, emergency interventions and pacification protocols (staff + meds + emergency care).

[#9] Pro-rated vehicle containment garage utilities & overhead allocation (electricity, HVAC, water, janitorial, admin).

[#17, #21, #22] Recurring costs for surveillance maintenance & data storage, instrumentation service contracts, and outsourced sample analysis (secure storage, server maintenance, instrument service contracts, and external lab fees aggregated).

[#12] Ongoing armed response readiness, specialized security training and equipment amortization (rapid-reaction team, non-lethal options, riot gear).

[#28] Annual legal, cover-story, PR, and liaison budget for fabricated ownership, maintenance contracts, and contingency payments to local authorities.

[#14] Operational costs per detainee (food, utilities, amenities, medical visits) aggregated for two humanoid subjects.

[#4, #5, #30, #31] Continuous fuel (~$13k–$18k/yr), engine/vehicle wear & maintenance, backup power fuel/maintenance, and hazardous waste disposal; aggregated logistics/transport costs.

[#26] Annual refresher training, audits, and consumables for memetic/cognitohazard mitigation protocols.

[#32] Recurring secure backups, colocation, encrypted storage, and cybersecurity maintenance.

[#24] Consumables, PPE, archival supplies (gloves, Tyvek, cleaning, archival sleeves) for daily handling and human interaction.

[#3] Environmental permits, emissions testing, and annual reporting driven by continuous engine operation and hazardous-waste handling.

[#29] Annual recertification and refresher training for security/technical personnel.

[#8] Periodic non-destructive testing / inspection and re-welding work on welded side doors/partitions.

[#25] Power and minor maintenance for archival locker/climate control for SCP-5472-3 (midpoint of $500–$2,000/yr).
