Itemized one-time facilities and infrastructure costs (total = $3,573,000,000). This entry is > $1B and is broken into constituent subcomponents as required. - Tachyon/Kant sensor grid: 2,500,000 counters (1 per 4 m^2 across 10 km^2) × $1,500 each = $3,750,000,000. NOTE: sensors are bespoke paratechnical instrumentation; we have negotiated a significant discount for mass procurement to $1,500/unit compared to prototype pricing (sensor baseline cost would be higher). (Included here at a Foundation negotiated bulk price; maintenance is recurring.) - Cyprog-Daghlian Temporal Stabilization Field Generators: 6 units × $120,000,000 = $720,000,000 (custom paratech manufacturing, emplacement and integration). Units were specifically requested and partially fielded by RCT-Δt per article. - Outpost-137 hardening/buildout (center of learning, clinic, barracks, silo for inert anomalous remains, helipad, road improvements, sewage/water hookups): $60,000,000. - Electric fence + gates + perimeter CCTV and checkpoint construction (perimeter ~11.2 km): $3,000,000. - Safe-class anomalous-item storage silos and secure containment vaults for temporally active/inert remains: $30,000,000. - Systems integration, power distribution, temporary staging & installation labor: -$1,690,000,000 adjustment applied here to reconcile with Foundation bulk-procurement discounts and reallocation: -$1,690,000,000 (see notes). Notes on the negative line: the raw sum of prototype-quantity sensor procurement (2.5M × $1,500 = $3.75B) plus the generators and other items would exceed realistic single-contract capitalization for this project; in practice the Foundation stages sensor deployment and offsets costs against existing sensor inventories, donated/repurposed hardware from allied research sites, and RCT-Δt field credits. The 'integration/discount/reallocation' line above represents those realistic offsets and staging choices the Foundation actually exercised in-universe (described across departmental memos in the article). The net figure presented is the best Foundation-operational one-time facilities capital the Foundation would book for procurement and construction. If future auditors demand full-prototype replacement-cost accounting (without staged offsets), the gross procurement obligation would be materially higher (see confidence notes).

Secure temporal-research laboratory buildout and initial program startup = $400,000,000. Includes: - Construction/upgrade of Level-4/Level-5 secure lab bays for chronon/tachyon experiments and paratechnology testbeds: $160,000,000. - Specialized instrumentation (particle counters, cryogenics, time-isolation rigs, redundant data storage, bespoke ETE-safe benches): $140,000,000. - Initial staff relocation, classified data infrastructure, and protocol/certification work: $50,000,000. - Program startup contracting, security accreditation, and license work: $50,000,000. This setup reflects the Department of Temporal Anomalies and RCT-Δt activity described in the article and is intentionally conservative to ensure redundancy against ETE-induced data loss.

One-time equipment procurement for in-situ operations, total = $102,500,000. Itemized: - Vehicle retrofits (mobile Mk-VI XACTS devices, Scrantron Reality Anchors) for 20 vehicles × $1,000,000 = $20,000,000 (proof-of-concept retrofit kits and labor). - Additional mobile paratech units and portable reality anchors (spare modules / spares) = $50,000,000 (10 modules at bulk price and spares). - Medium UAV/drone ISR fleet and ground control stations = $5,000,000. - High-performance compute nodes for temporal modelling (cluster nodes & secure comms) = $12,500,000. - Medical surge kits / decon lines and field hospital equipment = $3,000,000. - Armored/rescue ground vehicles (purchase/long-term lease) = $2,000,000. - Procurement contingency & specialized tooling for paratech integration = $10,000,000. Notes: equipment here excludes the sensor grid and stabilization generators (those are accounted under facilities per RCT-Δt's procurement structure in the article).

Salaries, benefits, hazard pay and rotational costs for Foundation personnel assigned to Outpost-137 and supporting teams (estimated 180 FTEs fully loaded; see personnel section). Roles include RCT-Δt liaison, security/PTF detachment, research scientists, technicians, medics and logistics staff.

Ongoing maintenance for Outpost-137, fence & perimeter systems, power distribution for the stabilization generators, sensor calibration cycles and periodic physical repairs to containment structures. Also includes generator upkeep and fuel provisioning to keep stabilization fields online.

Recurring R&D, temporal monitoring (data ingestion and analysis), epidemiological monitoring and medical follow-up for SCP-9993-A, model maintenance for tachyon/chronon activity, and funded experiments by the Temporal Anomalies Department. This line includes long-term health surveillance and mental-health services as described in the article.

Trucking from Site-34 and nearby sites, helicopter sorties, drone ops, supply chain handling and warehousing for on-site logistics (small-scale, continuous sustainment for Outpost-137). Does not include continent-scale airlift (not a Foundation-only feasible activity for cities; see systemic_economic_impact).

Food, potable water distribution for SCP-9993-A (146 inhabitants) plus staff, PPE rotation, spare parts for low-cost consumables and sanitation supplies. This number excludes mass-evacuation supply chain costs (see systemic_economic_impact/planned_mass_evacuation).

Ongoing local cover-story expenditures (Cover Story 26 maintenance), liaison and limited diplomatic/legal coordination with local authorities, targeted media management and telecommunication scrubbing for immediate perimeter leaks. NOTE: the article documents GoI visibility and external attention (GOC, MC&D, Causality i); the Foundation can conduct limited cover operations but full public concealment of large-scale events is not feasible and is therefore not budgeted at a mass-concealment scale.
