SCP-1683

Expected annual

$2.6M

One-time setup

$7.3M

Annual recurring

$2.5M

Personnel

Initial capital to acquire and harden a residential block and install specialized sensors/robotics is roughly $7.29M one-time; annual operating costs are about $2.50M driven primarily by security/research staffing, D‑Class program costs, and ongoing monitoring/response.

🏗️ One-Time Capital Costs Total: $7.3M

Facilities $2.8M

[#1, #2, #3, #17] Property acquisition, structural reinforcement, refractory lining, and fire-suppression/HVAC upgrades (closing/due-diligence, heavy engineering, refractory installation and physical upgrades).

Contingency Reserve $2.8M

[#25] Capital reserve to cover escalation, relocation, litigation or large-scale specialist procurement.

Dedicated Space Capability Build $1.2M

[#15] Optional one-time build of a dedicated small-satellite / deep-tracking capability (alternative to per-task purchases).

Equipment $363K

[#4, #5, #10, #11] Hardened sensor suite initial purchase, redundant generator(s) install, remote/robotic manipulators, and telescope lockout/interlock hardware.

Initial Research And Lab Setup $30K

[#14] One-time secure archival shelving, conservation equipment and initial laboratory setup for recovered materials.

Shell Company Setup $25K

[#24] One-time setup costs for front company/billing, legal incorporation and initial shell operations to support cover story.

Sop Development $20K

[#21] One-time SOP development for entry, activation response, and special handling protocols.

Ppe Initial Purchase $10K

[#12] One-time aircraft-technician-grade hearing protection initial procurement for staff (~50 personnel).

🔄 Annual Recurring Costs Total: $2.5M/yr

Staff Wages $1.6M/yr

[#6, #7, #13, #26] Ongoing salaries/benefits for continuous security shifts (guards + supervisors), specialized quick-response/containment team, scientific/research staff, and site administrative oversight.

D Class Program $270K/yr

[#8] Costs for D-Class recruitment, lodging, food, medical screening, transport and replacement for a small pool (~6 D-Class).

Research And Monitoring $225K/yr

[#14, #15] Annual lab operations/analysis budget plus per-task satellite/radar tracking purchases (assumes occasional paid tasking rather than building own capability).

Cover Story And Legal $115K/yr

[#18] Ongoing cover-story maintenance, PR/legal fees, permits, fake work orders and local liaison payments as required.

Facilities Maintenance $75K/yr

[#2, #3, #16, #17] Routine maintenance and baseline repairs including replacement of sacrificial liners, refractory repairs, HVAC/fire-suppression upkeep and periodic structural maintenance after activations.

Per Activation Experiment Costs $60K/yr

[#9, #16] Budget for single-use experiment consumables, replacement of sacrificial panels and immediate forensic/clean-up assuming a small number (~3) of controlled activations per year at ~$20k each.

Amnestics And Witness Suppression $60K/yr

[#19] Amnestic drugs, medical personnel and campaign costs for witness suppression contingencies.

Medical And Psych Support $30K/yr

[#20] Regular hearing tests, medical monitoring, PTSD/psychological support and associated care for staff.

Logistics And Transport $15K/yr

[#22] Chain-of-custody secure transport, couriers and secure vehicle operations for recovered items.

Sensor Maintenance And Data Storage $15K/yr

[#4] Annual maintenance, replacement budget and secure data storage for high-speed camera/acoustic/thermal/seismic/radiation instrumentation.

Robotic Maintenance And Consumables $10K/yr

[#10] Maintenance, consumables and replacement budget for remote manipulators and retrieval tooling.

Training And Drills Refreshers $10K/yr

[#21] Annual refresher training, drills and SOP updates following initial SOP development.

Shell Company Maintenance $9K/yr

[#24] Annual maintenance costs for shell company bookkeeping, bank accounts and minimal legal compliance to sustain cover operations.

⚡ Cost Scenarios

📊 Baseline (baseline) $2.5M/yr

78.0% probability / year

Normal year with controlled experiment cadence (few activations), routine maintenance, and no major incidents.

scheduled experiments routine maintenance

🚨 Minor Incident $2.7M/yr

15.0% probability / year +$195K vs baseline

Single notable activation causes extra repairs, increased forensic/amnestic workload and overtime response.

unexpected activation replacement of sacrificial panels increased amnestic campaigns

🚨 Major Incident $3.5M/yr

5.0% probability / year +$1.0M vs baseline

Activation or containment failure causing major structural damage to corridor/site requiring heavy repairs and equipment replacement.

structural damage sensor suite replacement temporary relocation/major repairs

🚨 Political Exposure $4.0M/yr

2.0% probability / year +$1.5M vs baseline

Local publicity or law-enforcement scrutiny forces expensive legal/cover operations or relocation efforts.

media exposure local investigation forced relocation

👥 Personnel 23 total

Role	Count	Notes
Security Officer / MTF Agent	10	[#6] Day-to-day guards covering 3 shifts (example: 8–10 guards).
Security Supervisor	2	[#6] Supervisory staff for perimeter and barred entrance monitoring.
Quick-Response / Containment Team	4	[#7] Armored specialist response team for breaches and alarms.
Research Scientist	4	[#13] Scientists and analysts (audio/video/astro/materials) to manage experiments and data analysis.
Site Director / Administrative Staff	3	[#26] Site leadership, admin, HR/procurement time allocated to Site-142 oversight.

📋 Confidence Notes

Detailed line-item estimates exist, but the anomalous high-temperature effects and uncertain activation frequency introduce wide uncertainty in repair/contingency needs and long-term costs; ranges are broad and escalation could be orders of magnitude higher.
