# Special-purpose civil installation delivery

## 1. Scope and Applicability

This method covers actual physical construction, installation and accepted delivery of military engineering works, satellite launching sites, waste dumps/incinerators and nuclear-material processing facilities. The shared object is a special-purpose installation with a delimited site, system interface and functional configuration, not a construction service or a bundle of materials. CPC53290 supplies classification context; routes are not interchangeable technologies. An n.e.c. work must establish exclusion from other construction categories and complete its own real route from project evidence.

Ordinary buildings and standalone roads, bridges/tunnels, ports, waterworks/dams, power/mining/general manufacturing facilities, sewage/water-treatment and recreation works are not new entities under this method. Integral roads/buildings/utilities have explicit interfaces and are counted once; necessary permanent process systems cannot be omitted by relabelling the output a civil shell. Nuclear routes retain the real nuclear-material treatment scope, with reactor generation assigned to power facilities; landfill, incineration and nuclear operations are not merged by the word waste. No default recipe, mass per installation, life, design load, emission or compliance approval is assigned.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.constructions-and-construction-services.constructions.special-purpose-civil-installation-delivery |
| classification_refs | CPC 3.0 53290 — Other civil engineering works |
| covered_products | Accepted forts/blockhouses/bunkers/military ranges and test centres, satellite launching sites, waste dumps/incinerators, nuclear-material treatment/processing installations with measured functional configuration; n.e.c. facilities require separate route evidence |
| excluded_products | Construction services; bulk materials and factory-gate equipment; ordinary buildings; other dedicated construction categories; post-handover operation, maintenance, closure and decommissioning |
| representative_product | One complete special-purpose civil installation with declared route, site, as-built configuration and acceptance scope; no single default technology represents every branch |
| production_route | Actual site/civil works → required containment/protective/thermal/launch/nuclear installation → real inspection and commissioning → delimited physical handover |
| market_state | Fixed installation delivered at the declared acceptance endpoint, not lifetime operating service |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Constructed special-purpose installation performing the declared site function within its actual route and system interface |
| How much | One complete delivered entity; measured site area, lengths/heights, cell volumes and actual capacity are route-specific qualifiers |
| How well | Matches the same as-built specification, operating conditions, component completeness and actual acceptance evidence; regulatory authorization is not inferred |
| How long or cycle | One actual construction-to-declared-handover cycle; no service life or future operating cycles assigned |
| reference_flow_link | `accepted_installation` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Accepted complete special-purpose civil installation |
| Reference flow property | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` |
| Reference unit group | Units of items `5beb6eed-33a9-47b8-9ede-1dfe8f679159` |
| Reference unit | item |
| Required qualifiers | facility identifier/route; site and interfaces; complete system/retained-asset register; measured geometry and actual functional capacity; structure/materials/conditions; construction dates; acceptance and cold/hot/active-test endpoint; upstream/logistics/operation/maintenance/demolition coverage and gaps |

item is the single-count display alias of public Item(s). Every inventory row and collection protocol is attributable per declared reference flow, which is the same one physical entity above. Site area/dimensions/capacity qualify the function; do not infer area, length or mass from count without an independently supported physical relationship, or replace the entity with cost, operating throughput or assumed life. Required qualifiers belong in the data package; absence makes the reference definition incomplete.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_count | reference product | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | item | Output is 1 item of the same accepted complete installation; use cp_acceptance. All rows/protocols aggregate per declared reference flow; item and 件 are public Item(s) single-count aliases. |
| volume_state | fresh_concrete; soil_disposal; site_water; washwater; groundwater; fresh_discharge; shield_concrete | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 | Use cp_civil, cp_waste, cp_water and cp_install to retain actual volume state; bank/loose soil, fresh concrete and supply/extraction/discharge water are distinct. Volume-to-mass uses measured/evidenced density at the same state, temperature/moisture/salinity; no default 1000 kg/m3. |
| sheet_area | hdpe_liner; geotextile | Area `93a60a56-a3c8-19da-a746-0800200c9a66` | m2 | cp_liner records actual supplied/installed area, thickness, overlap and coupons; area numerator is attributable per declared reference flow. No kg inferred without evidenced areal mass/density. |
| electricity_energy | electricity_lv | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Preserve public Net calorific value and energy unit group; cp_activity records actual CN/<1 kV user conditions. Convert original kWh by 1 kWh=3.6 MJ, never confuse it with diesel mass. |
| asset_share | steel_formwork; crane_share | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | cp_assets uses measured net mass or traceable supplier weighing of the complete same-configuration asset, not facility mass. A separate dimensionless manufacture share requires lifetime-activity evidence and cumulative conservation ≤1. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Surveyed actual site, retained/clearance/remediation state and supplier-gate/site interfaces |
| starting_condition_role | Recorded construction start, not a zero-burden assumption for land, existing works or equipment |
| product_classification_scope | Special-purpose fixed installations identified by CPC3.0 53290 context and actual exclusion boundaries |
| recursive_input_rule | Retained/purchased same-category installation modules are real assets with supplier and prior-burden records, not recursively created complete entities |
| upstream_dataset_requirement | Separately link upstream materials/equipment and logistics matching real material/interface/route; disclose gaps |
| disclosure | Route/function/completeness, site geometry, dates/acceptance, embedded components, shared-asset shares, water/releases/land/noise, later stages and unmeasured gaps |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_entity | reference product | The output is the constructed physical installation, including integral permanent equipment/services and real acceptance needed for its declared function. Standalone ordinary buildings, roads, dams/flood schemes, power plants, manufacturing/mining plants, sewage/water-treatment plants and outdoor recreation works remain their own categories. Bound shared interfaces and account for every integral asset once. | `un-cpc-civil-2025` |
| boundary_stage | dataset | The base foreground covers actual supplier-gate-to-site logistics, surveyed site preparation, civil construction, route-specific installation, temporary works, inspection and commissioning through the declared handover. Supplier material/equipment manufacture is linked separately with compatible datasets and explicit gaps. This is not evidence of complete cradle-to-gate or full lifetime coverage. | `un-cpc-civil-2025` |
| boundary_route | all inventory rows | Select the real route before collecting the inventory. The cards are distinct conditional exchanges, not a universal recipe. Reconcile the full as-built functional-system register: landfill cells/liners/leachate; military earth protection/structures/targets/support; launch pad/trench/ground fluid and control systems; incinerator reception/thermal/cleaning/ash/recovery; nuclear processing/containment/shielding/safety. Add one exact atomic row for every actual missing component, batch ingredient, test consumable, packaging, waste and release. A residual n.e.c. work needs its own evidenced route/system closure and exclusion check; this PCR alone does not establish its technical design. | `un-cpc-civil-2025`; `epa-industrial-waste-guide`; `dod-firing-ranges-2025`; `nasa-launch-construction-2018`; `jrc-waste-incineration-2019`; `iaea-ssr4-2017` |
| boundary_embedded | all inventory rows | Record either supplied complete assemblies or their actual on-site fabrication inputs for the same scope; do not count both. Exclude contained steel/lining/filter/controls from separate rows unless genuinely outside the assembly. Record existing foundations and reused equipment with retained-state, repair and prior-burden evidence. Maintain internal versus external material/water interfaces. | `jrc-waste-incineration-2019`; `iaea-ssr4-2017` |
| boundary_tests | acceptance | Declare mechanical/cold/wet/hot/active test stages actually needed and completed. Include actual test fuel, water, electricity, purge substances, trial feed, products, residues and measured releases before the endpoint, adding exact individual rows. Do not assume a launch/firing/active-nuclear/waste-incineration trial occurs or is zero-burden. Necessary unfinished tests prevent complete handover claims; split later regular operation by records. Test results do not establish regulatory approval. | `dod-firing-ranges-2025`; `nasa-launch-water-test-2018`; `iaea-ssr4-2017` |
| boundary_environment | site_support | Separate direct resource extraction, purchased water, waste-liquid transfers and liquid receptor releases. Land transformation/occupation requires measured prior/post land use and actual area/time; noise requires source/receptor, levels, duration/frequency and method, not a fabricated additive mass exchange. Actual pollutants, soil contamination, blasting and marine releases need separate identity/activity evidence. Missing characterization or measurements remain gaps, not zero impacts. | `epa-construction-dust-1995`; `epa-concrete-washout-2012` |
| boundary_later | dataset | Operating waste receipt/incineration, launches, military use and nuclear material processing after handover are separate stages. Maintenance, relining, component replacement, closure, demolition, radioactive decommissioning and destinations are separately modelled only from evidenced schedules and quantities; no default life, waste conversion or recycling credit. Construction commissioning is not hidden in later operation. | `un-cpc-civil-2025`; `iaea-ssr4-2017` |

###### Fresh ready-mixed Portland-cement concrete before placement (`fresh_concrete`)

Record only actual purchased fresh concrete at the batch-plant gate, before placing, with delivery volume, mix identifier, strength/exposure specification and acceptance tickets. Record transport, pumping, vibrating and curing separately. The placed-concrete identity does not represent this input; site batching requires separate cement, each aggregate, admixture and mixing-water rows instead of counting both routes.

- Selected flow: Fresh ready-mixed Portland-cement concrete before placement
- Flow property / unit: Volume `93a60a56-a3c8-22da-a746-0800200c9a66` / m3

###### gravel 2/32 (`gravel_drainage`)

Use only actual undried 2/32 gravel from a matching wet/dry quarry plant gate. Its use in drainage or a base is conditional on approved project grading and filtration design, not prescribed by this PCR. Keep delivered wet mass and moisture evidence; other sizes, washed state or recycled aggregate require separate rows/identities.

##### Waste flows

###### Hardened Portland-cement concrete offcuts sent for treatment (`concrete_debris`)

Record segregated hardened concrete leaving the construction boundary by weighbridge and destination. Retained fill and returned fresh concrete are separate; neither a mixed construction-waste flow nor recycled aggregate product establishes this waste identity.

- Selected flow: Hardened Portland-cement concrete offcuts sent for treatment

###### Non-contaminated excavated mineral soil sent for disposal (`soil_disposal`)

Conditional on actual export for disposal. Collect measured bank/loose volume separately, water content, contamination assessment, waste status and destination. On-site cut-and-fill is an internal transfer, not an exported exchange. Contaminated soil requires its own material/contaminant specification.

- Selected flow: Non-contaminated excavated mineral soil sent for disposal

###### Diesel fuel (`diesel`)

Record actual diesel consumption of excavators, compactors, pumps, cranes, generators and attributable delivery/return trucks, disaggregated by equipment and work package. This identity has unspecified grade, formulation, refinery and geographic supply: declare the real supplier, batch, fossil/biogenic fractions and boundary. It represents fuel, not a combustion-service exchange or an emission quantity.

###### Alternating current (`electricity_lv`)

Only actual CN grid-average consumption supplied to the user at <1 kV uses this identity. Meter construction, liner welding, equipment installation and tests separately by work package. Preserve public Net calorific value/MJ; record kWh and convert exactly by 3.6 MJ/kWh. Other countries, voltages, contractual mixes and generator output need distinct verified identities; do not also count generator output and the fuel used to make it.

###### Supplied liquid freshwater for construction and acceptance tests (`site_water`)

Collect actual metered freshwater supplied at the declared site delivery interface for curing, dust suppression, washout, pressure testing or deluge tests. Declare source, treatment, supplier and distribution links. A Hong Kong treatment-plant gate flow or a Korean soil-washing case is not generic site supply; do not use water-resource or effluent identities. Quantify internal recirculation separately without counting it as new supply.

###### Reusable fabricated steel formwork panel manufacture share (`steel_formwork`)

Include only the attributable manufacture burden of actual reusable fabricated panels. Collect same-configuration net panel mass, asset identifier, prior allocations and evidence for the dimensionless project share. Sum shares across all projects/periods/uses must not exceed one; unknown reuse history or lifetime activity remains a review item. Record present transport, cleaning and repair separately at their actual quantities.

Conditional on actual direct extraction of fresh groundwater for construction/dewatering/test use within the foreground. This is a Resources from water/renewable material resource, Volume/m3 identity. Record extraction location/country, aquifer, metered volume, use and return; contaminated extracted groundwater and supplied product water are distinct.

###### Collected alkaline concrete washout water sent for treatment (`washwater`)

Conditional on contained liquid washout actually exported for treatment. Meter the liquid, retain pH/composition and receiver records, and separately weigh settled concrete solids; the two are not a single exchange. No assumption of a direct water/soil release is allowed. On-site recovered washwater remains internal until it crosses the boundary.

Use only actual external-air particulate release with particle size unspecified, after controls. Collect source operation, weather, soil moisture/silt, receptor boundary and measured or independently justified site-specific release. The historical AP-42 overall TSP construction factor is not a PM2.5/PM10 factor or a default for this category.

#### Inputs

##### Product flows

###### Clay (`liner_clay`)

Only actual natural clay supplied at a mining-site interface uses this raw-clay identity; document supplier mineralogy, moisture and delivery/transport. Compaction, lift geometry and permeability are separately measured construction conditions, not properties supplied by the UUID. In-situ reused soil and geosynthetic clay liners are distinct routes. The cited historical US guide supplies component examples, not worldwide mandatory thickness/permeability.

###### Installed firing-range extraction fan assembly (`range_fan`)

Only for an actual covered/enclosed firing range requiring this installed extraction system. Record fan configuration, duty and control interface, installation and measured acceptance airflow/control tests; actual filter assemblies are separately recorded.

###### Fabricated steel launch flame-deflector assembly (`flame_deflector`)

Only for a documented steel-deflector launch-site design. Use supplier net as-built assembly mass or reconciled same-scope BOM, excluding packaging; record actual supports, liners and embedded content. NASA Pad39B is a historical assembly example, not a default material quantity, rocket capacity or life. Site-fabricated plates/weld inputs replace, rather than supplement, the same complete assembly burden.

###### Installed rotary-kiln waste-incinerator assembly (`incinerator`)

Only for actual rotary-kiln technology. Count the accepted supplied assembly and declare steel shell, drive, refractory and burner inclusion from the supplier BOM. Grate/fluidised-bed/other thermal routes require their own exact furnace row. The facility additionally reconciles reception bunker/crane, fire protection, boiler/heat recovery, flue-gas treatment, ash handling, wastewater and stack where present; a furnace alone is not the complete delivered incinerator facility.

###### Fresh heavyweight cement concrete for nuclear shielding (`shield_concrete`)

Only where the real nuclear fuel-cycle design specifies this concrete. Collect actual aggregate species, mix, density at placement, shielding thickness, openings, QA and delivered/placed volumes; ordinary concrete tickets do not prove shielding performance.

Conditional on an actual glovebox process and containment configuration. Count assembled accepted boxes with supplier material/lining/window/glove/ventilation boundary, leak/containment tests and equipment QA.

###### Accepted complete special-purpose civil installation (`accepted_installation`)

One physically delimited accepted installation of the declared route and configuration, including permanent systems necessary for the specified delivered function. Geometry/capacity and acceptance endpoint come from as-built records. A waste cell, launch site, bunker or processing plant is not interchangeable merely because each is counted once; identify the exact entity. Missing necessary commissioning or systems prevent a complete delivered-entity claim.

## 7. Allocation and Co-product Handling

The attribution requirements below are authored foreground-accounting rules grounded in actual project subdivision and cp_assets records; classification evidence does not establish allocation coefficients. Unknown beneficiaries/activity/lifetime data remain under review with no default shares.

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_subdivide | construction work packages | Use measured physical subdivision before allocation: delivered entity/cell, retained asset, regular-operation output and other project beneficiaries must have separate identifiable records. Shared logistics, test utilities and civil structures use traceable actual meters, work activity and geometric interfaces. Cost alone does not establish physical attribution; unknown shares remain review. |  |
| allocation_assets | steel_formwork; crane_share | Maintain a cross-project/period/reuse asset register. Manufacture share is dimensionless and supported by actual lifetime activity or a justified beneficiary basis; cumulative assigned shares ≤1. Do not reset full burden each project or invent life/uses. Physical net mass/configuration and share are distinct fields. Current fuel, transport, repairs and new consumable replacement are separately attributable; incomplete lifetime evidence blocks a final allocated burden. This is an authored foreground-accounting requirement based on cp_assets, not a CPC classification rule. Where service is expressed on a comparable actual activity basis, the project share is attributable project activity divided by evidenced total same-asset service; retain prior shares and update the common denominator consistently. |  |
| allocation_residues | waste and trial outputs | Do not grant automatic avoided-production or energy-recovery credits. Segregated exported scrap/soil/concrete, returned products and internal reuse have distinct status, quantity and receivers. If saleable commissioning output coexists, subdivide actual activities or document a reasoned physical allocation with complete balances and uncertainty; never substitute operating waste throughput for the construction reference. | `jrc-waste-incineration-2019`; `epa-concrete-washout-2012` |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| attribute_entity | all inventory rows | Aggregate each measured attributable atomic exchange within the same accepted entity; output is 1 item with no further division by assumed mass/area/life. Physically subdivide shared interfaces first; unknown stays unknown. | raw ledgers; cp_acceptance; actual interface/attribution records | each atomic quantity per declared reference flow |  |
| convert_energy | electricity_lv | MJ = measured kWh × 3.6; preserve original readings and actual voltage/region. | cp_activity; kWh | MJ | `nist-si-energy` |
| convert_density | fresh_concrete; soil_disposal; diesel; site_water; shield_concrete | Only when a mass/volume conversion is needed and same-state density is evidenced: kg = measured m3 × same-state kg/m3. Retain raw quantity, density method, temperature/moisture/salinity and uncertainty; never guess unknown density. | measured volume; same-state density evidence; relevant collection protocol | traceable converted kg and original m3 |  |
| allocate_manufacture | steel_formwork; crane_share | Attributable manufacture-equivalent kg = measured same-configuration asset net kg × evidenced dimensionless manufacture share; sum across every project/period/reuse for each asset ≤1. Unknown lifetime-activity/beneficiary evidence prevents final shares; current operation is separate. | cp_assets; net mass and cumulative-share records | manufacture-equivalent kg per declared reference flow and unresolved shares |  |
| material_balance | all inventory rows | For the same material/state reconcile receipts + opening stock = installed/consumed + returned + exported waste + closing stock + evidenced loss; do not duplicate internal transfers. Do not add different volume states or solid/liquid phases; explain discrepancies. | same-state ledgers; original measurements/destinations | material balance and discrepancy disclosure | `epa-concrete-washout-2012` |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |

| quality_coverage | all inventory rows | Cover every actual work package/subcontract, permanent system, test and atomic exchange; label occurred, evidenced absent, unknown and gaps | full system/BOM and amount/destination ledgers |
| quality_source | dataset | Historical sources are bounded component/method examples; no design numbers/life transferred; current project standards/authorization independently checked | original sources, scope/date and actual project technical evidence |
| quality_identity | all inventory rows | Match actual material/form/route/geography, reference property/unit and environmental compartment; unresolved identities retain exact rows; official Chinese names agree | verified originals and project qualifiers |
| quality_time | dataset | Use complete actual construction/test period; disclose supply-year/technology representativeness, rework and metering gaps | schedule, shift logs, calibration and correction evidence |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validate_scope | dataset | Verify the route, site and complete physical system against the as-built/acceptance register and classification exclusions. Missing required systems/tests must be reported as incomplete; an empty or unrelated route is not a complete facility. | `un-cpc-civil-2025` |
| validate_basis | all inventory rows | Require 1 item output and per-declared-reference-flow inventory/protocol coverage for the exact same accepted installation. Check actual geometry/capacity, volume state, stock/returns/waste and unit conversions. No implicit count-to-mass/area/lifetime conversion or unsupported density. | `un-cpc-civil-2025` |
| validate_identity | all inventory rows | For each selected identity recheck substance/form, route, grade, region/interface, reference property and unit group; elementary compartment/subcompartment and temporal nature must match. Unresolved UUIDs stay specific and registered. Official localized names must agree. Fuel occurrence does not prove emissions, NOx-equivalent does not prove molecular NO/NO2, and untreated effluent transfer is not water emission. | `epa-concrete-washout-2012` |
| validate_closure | dataset | Check mandatory and actual conditional work packages, installed-system/BOM coverage, commissioning records, environmental gaps and cumulative asset shares. Unmeasured rows and omitted significant interfaces are unresolved coverage, never zero. Report checked/skipped scopes and uncertainty; do not assert full cradle-to-gate, lifetime or regulatory/methodology approval. | `iaea-ssr4-2017`; `epa-construction-dust-1995` |
