1. Scope and Applicability

This PCR defines the foreground methodology for a complete accepted long-distance communication or high-tension power-line construction object. It covers overland, underground and submarine transmission lines, long-distance railway electricity lines, and transformer stations/pylons belonging to that delivery, including separately accepted stations/supports where their complete physical interface is declared. The functional product is the delivered civil/electrical/communication entity, not installation labour or a bag of materials. CPC 3.0 53242 supplies scope context only (UNSD explanatory notes, p.280).

Exclude low-tension/local distribution (53252), fluid/gas pipelines, isolated factory cable/transformer manufacture, whole railway track infrastructure outside its line-power interface, and operational energy/telecom transmission service. Select every actual design branch and explicitly record its beginning/ending state, site, geometry, complete configuration, acceptance criteria and included/excluded lifecycle stages. The default is construction-to-accepted-delivery foreground, with upstream products and transport linked separately; it does not by itself establish complete cradle-to-gate or whole-life coverage.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.constructions-and-construction-services.constructions.long-distance-line-infrastructure-delivery
classification_refs	CPC 3.0 53242 — Long-distance communication and power lines (cables); context, not accepted mapping
covered_products	Accepted complete line object/defined section, transmission station or pylon with explicit endpoints and support/ancillary interface
excluded_products	Local low-tension distribution; pipelines; standalone component manufacture; construction-service contract; operation service

3. Reference Flow

Field	Value
What	Accepted long-distance communication or power-line infrastructure delivery
How much	1 item
How well	Meets the actual declared transmission/communication function and signed configuration/test requirements; disclose rated voltage/capacity or optical configuration, physical interfaces, geometry and limits
How long or cycle	One actual construction-and-acceptance event with real start/end/acceptance dates; future life, repair and operation are not part of this reference cycle
reference_flow_link	`reference_line`

Field	Value
Reference amount	1
Reference product flow	Accepted long-distance communication or power-line infrastructure delivery
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	object ID; actual site/country; start/end/acceptance dates; long-distance function; endpoints/chainage and actual route length; physical cable/conductor lengths and counts; rated voltage/capacity or fibre/type/system configuration; installed support/civil/station/terminal interfaces; actual dimensions and ground/seabed conditions; new/retained/replaced assets; supply state; applicable test results and signed acceptance; foreground/upstream/transport/operation/demolition coverage; applicability evidence under boundary_qualifiers for genuinely absent route/cable/rating attributes

item is the display alias of public Item(s); Chinese 件 denotes exactly the same Number of items unit. Each object is uniquely identified; no reference mass M or default per-item/per-km mass is defined. Optional results per actual route metre require an explicitly declared measured compatible route length and unchanged complete object burden; physical cable length must never silently replace route length. Required qualifiers belong in dataset metadata, process notes and reference-flow description; missing qualifiers make the concrete reference incomplete.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
`measurement_reference`	Accepted long-distance communication or power-line infrastructure delivery	Number of items `01846770-4cfe-4a25-8ad9-919d8d378345`	item	The fixed reference output is 1 item, one complete declared accepted object; cp_delivery verifies configuration and count. No mass conversion is implied.
`measurement_components`	material, component and waste rows whose native properties are mass, length, volume or count	Mass; Length; Volume; Number of items	kg; m; m3; item	Retain each actual primary property/state. Measure component mass, physical cable length, wet concrete volume and device count separately; component conversion requires actual same-design/state records in cp_materials; waste conversion uses cp_waste with its measured same-state volume, bulk density, moisture and provenance. Do not use public secondary screening factors. Exchanges declared in energy, transport and land units retain Net calorific value/MJ, Goods transport (massdistance)/tkm and area-time/m2*a under their specific rules. This does not impose MJ on a mass-based fuel: marine_fuel retains Mass/kg under cp_marine, with batch density for any volume conversion; component-specific cp_materials requirements do not apply to that separately collected fuel. No conversion of those quantities into material mass is implied.
`measurement_energy`	electricity and diesel rows declared with the native Net calorific value/MJ; excludes marine_fuel	Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66`	MJ	Retain public primary property; actual meter/batch data in cp_energy support kWh or mass/volume to MJ, with no assigned demand/density/heating value. The separately supplied marine_fuel retains its declared Mass/kg and cp_marine tank/bunker balance; volume conversion requires actual same-batch density. Auxiliary heating-value data do not create a second fuel input or replace that native kg exchange.
`measurement_resources`	Water and land	Mass; Volume; Area; Area*time	kg; m3; m2; m2*a	Keep resource input, wastewater and receptor release distinct; sea-water resource is Mass/kg with actual mass or volume and same-salinity/temperature evidenced density, never an assumed density. Preserve original volume balance separately. m2*a uses actual measured area/dates with 365-day conversion only, not asset life.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Documented actual site/route baseline and existing assets before this delivery work, with separately supplied completed materials/equipment received at their stated gates
starting_condition_role	Construction foreground start; existing condition and upstream receipts are not assumed burden-free
product_classification_scope	Complete delivered long-distance communication/high-tension/railway-power lines and transmission stations/pylons; excludes local low-tension distribution
recursive_input_rule	Record any in-category purchased/reused line section or station once with its source/interface and attributed prior burden; no recursive duplication of its construction
upstream_dataset_requirement	Link each actual material/component production gate, packaging, external transport and waste treatment separately with representative records; retain unlinked gaps
disclosure	Declare route branches, site, period, new/retained/replaced geometry, supply gate, actual work stages and tests, restoration, temporary/capital assets, allocation, environmental and lifecycle coverage, cutoffs and missing links

rule_id	Applies to	Rule	source_ids
`boundary_delivery`	Foreground stages	Include actual receiving/unloading, project survey/preparation, civil works, relevant line/station installation, site tests/commissioning, temporary removal and restoration through the signed delivery interface. Map all real branches; an absent branch needs documented not_applicable, not guessed zero.	`national-grid-overhead-2025`; `eirgrid-underground-2026`; `itu-submarine-g971-2024`
`boundary_qualifiers`	all reference qualifiers, cp_delivery geometry/fields, dq_geometry and publication metadata	Every object requires its identity, site/country, real dates, long-distance function, delivered physical interfaces, applicable dimensions and signed acceptance. Line sections require actual endpoints/chainage/route length and all delivered cable/conductor lengths/counts. For separately delivered stations or supports, measure the actual station/support geometry and interfaces; attributes of genuinely absent route/cable/rating branches are explicitly not_applicable with drawings/scope evidence, not zero or missing measurements. This exception applies to the required-qualifier list, all collection fields, geometry requirements and required_metadata. Unknown applicable values remain gaps; do not borrow an adjacent line or invent length/capacity.
`boundary_upstream`	Purchased materials, equipment and logistics	Manufacturing, quarrying/refining and supplier packaging are upstream. Link complete supplied components at their declared gate and actual transport legs; prevent counting embedded copper, steel, insulation, oil or gas again. A service dataset containing construction must not be added on top of this same foreground construction. Missing links must be disclosed before any expanded cradle-to-gate claim.	`eirgrid-underground-2026`; `national-grid-overhead-2025`
`boundary_existing`	Existing line assets and shared interfaces	Document pre-existing retained assets separately from new/replaced work. A purchased or reused in-category line section is one input with its source burden and interface; do not recursively re-create its installation or count it again in railway, station, wind farm or adjacent line datasets. Brownfield demolition needed before this delivery is identified separately; future demolition is outside.	`rdso-rail-ohe-2020`; `cpc3-explanatory-notes-2025`
`boundary_later_stages`	Operation, maintenance and end of life	Network transmission losses, delivered energy/traffic service, vegetation maintenance, leakage during use, repairs, replacements and end-of-life demolition/recycling are outside the default delivery inventory. Any extension declares actual scenario, dates, evidenced life/activity, replaced quantities and destinations separately; no default lifetime, salvage credit or full-life claim follows from acceptance.	`itu-submarine-g971-2024`; `ifc-power-ehs-2007`
`boundary_environment`	Environmental coverage	Separate technosphere water, direct freshwater/groundwater abstraction, contained waste liquids and actual direct receiving-medium releases. Inventory only evidenced chemical species/particle fractions with matching media and timing. Add actual route-specific contaminants, land changes, marine transfers and noise/habitat observations; unresolved identities or unmeasured potentially relevant releases are explicit gaps, not assumed absence.	`ifc-power-ehs-2007`; `eirgrid-submarine-2022`

6. Process Inventory Structure

Use the following atomic cards only when their individual physical conditions apply. The complete inventory is derived from the actual drawings/BOM and task ledger: retain required work for that design, document absent rows as not_applicable, and add each real missing component/chemical/waste/release as a specific atomic row with property/unit, collection and identity review. A blank UUID is a disclosed identity gap, not an instruction to substitute a broader flow. Direct releases are never presumed from equipment/fuel existence.

Process: Component receipt and external transport (`logistics`)

Check delivery tickets, supplier gates, actual transport legs and unloading. Road freight is one conditional mode card. Rail/sea freight, abnormal-load transport and returns require their own measured atomic service rows. Do not add direct truck emissions if already included in the linked transport service.

Inputs

Articulated Truck (`road_freight`)

When this actual vehicle mode delivers components or removes construction waste, collect each actual load, route distance and vehicle specification; record background service separately from site machinery fuel. Other modes need distinct actual rows. Adopt only the public diesel HDV cargo service with total vehicle weight 35.0–40.0 t, consumption mix to consumer. Payload, not gross vehicle weight, determines transport work; tkm is 1000 kgkm in its public unit group.

Process: Survey, access, excavation, foundations and reinstatement (`site_civil`)

Collect topographic/geotechnical survey and utility clearance; actual vegetation removal, topsoil stripping/storage, temporary access/pads, excavation/dewatering, foundation reinforcement/formwork/concrete placement/curing, joint chambers and drainage. Record HDD only at an actual trenchless crossing/shore approach. Distinguish retained excavated soil, imported fill and waste export. Restore topsoil, drains, roads and habitats actually disturbed; remove temporary crossing protection and works. Use actual dimensions and recipes, not generic trench depth or concrete per tower. Site batching, piling, asphalt reinstatement or coatings require their separate actual constituent/process rows; purchased wet concrete and its constituent manufacture cannot both be counted.

Crushed stone aggregate for construction access (`fill_aggregate`)

Conditional imported granular material for actual access tracks, working pads or substation platform. Record mineralogy, grading and supply state; retained on-site excavated material is an internal transfer.

Reusable steel concrete formwork (`steel_formwork`)

When steel formwork is used, attribute manufacture by the same identified formwork asset and measured mass, documented cumulative service and this project share. Sum of manufacture shares across all projects and periods must not exceed one; uncertain service denominator remains review.

Waste flows

Uncontaminated surplus mineral excavation soil (`excavated_soil`)

Actual surplus soil exported as waste; retain contamination tests and actual destination/compliance evidence. Missing testing or destination evidence remains a disclosed gap, not a reason to omit actual exported quantity or assume uncontaminated soil. Survey excavated/reused/exported volumes separately; mass requires weighbridge tickets or measured same-state bulk density. Contaminated soil needs its own row.

No separate exchange is declared here. Actual transfers of this type require their own measured atomic rows if present.

Process: Overhead line and railway-power installation (`overhead_install`)

For an actual line: receive/layout/erect supports by cranes and work platforms, torque/bond fittings, install insulators, string/sag/tension conductors and earth wire, install actual OPGW/ADSS and optical splices, and record temporary earthing/crossing protection removal. Pure aluminium, ACSR, ordinary steel earth wire, optical ground wire and railway contact/catenary wires are distinct. Actual railway feeders, masts/portals, droppers, tensioners, return conductors and traction-substation interfaces require complete measured configuration; the track/civil railway itself is a separate entity. Apply current project electrical/mechanical tests and actual wire geometry; no historical RDSO tension, alloy, span or speed default is imposed.

Transformer insulating oil (`insulating_oil`)

Only separately charged pure inhibited mineral transformer oil conforming to IEC 60296, at refinery gate, GLO screening identity. Exclude factory oil already included in transformer supply; ester/silicone/mixed oils need separate identities. The associated refinery screening dataset is not automatically a representative upstream production inventory.

sulphur hexafluoride (`sf6_air`)

Only measured or verified mass-balanced molecular SF6 actually released during site filling/testing to outdoor air, unspecified subcompartment, immediate release, CAS 2551-62-4. Retained charge and recovered gas are not emissions; indoor or delayed flows are different identities. A merely unexplained balance residual is not proof of leakage.

Process: Construction equipment, utilities and environmental transfers (`site_operation`)

Assign each measured site utility, plant fuel, water parcel, waste and direct release once to the actual task/route; this common ledger supports the branch processes and is not an extra copy of their fuel. Record crane, excavator, pump, winch, air-blower/compressor, concrete vibrator, testing equipment and actual vessel separately by equipment ID/activity. Additional fuels/lubricants or utilities need their own specific rows. Retain actual land transformation pairs, restoration, fugitive releases and spill evidence. Noise (airborne/underwater), vibration and habitat effects use location/time/spectrum/receptor observations; no invented sound-energy exchange or universal LCIA factor is assigned. Report unquantified environmental coverage.

Inputs

Product flows

Alternating current (`electricity_lv`)

Only actual CN user-side grid-average AC supply below 1 kV matching this public identity. Meter separate tasks including pumps, cranes, winches, cable blowing/jointing and acceptance equipment.

Waste flows

Discarded solid-wood cable drum (`wood_drum_waste`)

Only actual drums discarded during the included delivery/construction cycle, including pre-installation damage; distinguish supplier take-back/reuse from waste. Do not add another packaging manufacture input when the supplied cable inventory already includes that drum. Keep the actual discarded drum quantity and its collection, transport and treatment burdens. Any subtraction is limited to an evidenced duplicate input in the identified overlapping supply ledger, never the actual waste quantity. Metal drum fittings and plastic film leaving separately require separate waste rows. A broad wood packaging product cannot identify this waste.

carbon dioxide (fossil) (`co2_fossil`)

Only evidenced molecular fossil CO2, CAS 124-38-9, immediate release to outdoor air/unspecified from actual site or separately foregrounded vessel combustion.

All actual direct discharge to an identified freshwater receptor, including unpermitted or incident releases; record permit/compliance status separately without excluding a physical release. separately quantify specific dissolved/suspended contaminants as atomic releases from sampling. Do not count the same parcel as treatment wastewater; water resource input is not a discharge identity. Marine discharge needs another compartment row. Public identity is molecular water CAS 7732-18-5, immediate emissions to fresh water, Volume/m3; it does not identify any dissolved pollutant.

This index comes from verified structured.yaml and retains the canonical English rule text.

System boundary rules · 6

Rule ID	Applies to	Rule	Source IDs
`boundary_delivery`	Foreground stages	Include actual receiving/unloading, project survey/preparation, civil works, relevant line/station installation, site tests/commissioning, temporary removal and restoration through the signed delivery interface. Map all real branches; an absent branch needs documented not_applicable, not guessed zero.	national-grid-overhead-2025, eirgrid-underground-2026, itu-submarine-g971-2024
`boundary_qualifiers`	all reference qualifiers, cp_delivery geometry/fields, dq_geometry and publication metadata	Every object requires its identity, site/country, real dates, long-distance function, delivered physical interfaces, applicable dimensions and signed acceptance. Line sections require actual endpoints/chainage/route length and all delivered cable/conductor lengths/counts. For separately delivered stations or supports, measure the actual station/support geometry and interfaces; attributes of genuinely absent route/cable/rating branches are explicitly not_applicable with drawings/scope evidence, not zero or missing measurements. This exception applies to the required-qualifier list, all collection fields, geometry requirements and required_metadata. Unknown applicable values remain gaps; do not borrow an adjacent line or invent length/capacity.
`boundary_upstream`	Purchased materials, equipment and logistics	Manufacturing, quarrying/refining and supplier packaging are upstream. Link complete supplied components at their declared gate and actual transport legs; prevent counting embedded copper, steel, insulation, oil or gas again. A service dataset containing construction must not be added on top of this same foreground construction. Missing links must be disclosed before any expanded cradle-to-gate claim.	eirgrid-underground-2026, national-grid-overhead-2025
`boundary_existing`	Existing line assets and shared interfaces	Document pre-existing retained assets separately from new/replaced work. A purchased or reused in-category line section is one input with its source burden and interface; do not recursively re-create its installation or count it again in railway, station, wind farm or adjacent line datasets. Brownfield demolition needed before this delivery is identified separately; future demolition is outside.	rdso-rail-ohe-2020, cpc3-explanatory-notes-2025
`boundary_later_stages`	Operation, maintenance and end of life	Network transmission losses, delivered energy/traffic service, vegetation maintenance, leakage during use, repairs, replacements and end-of-life demolition/recycling are outside the default delivery inventory. Any extension declares actual scenario, dates, evidenced life/activity, replaced quantities and destinations separately; no default lifetime, salvage credit or full-life claim follows from acceptance.	itu-submarine-g971-2024, ifc-power-ehs-2007
`boundary_environment`	Environmental coverage	Separate technosphere water, direct freshwater/groundwater abstraction, contained waste liquids and actual direct receiving-medium releases. Inventory only evidenced chemical species/particle fractions with matching media and timing. Add actual route-specific contaminants, land changes, marine transfers and noise/habitat observations; unresolved identities or unmeasured potentially relevant releases are explicit gaps, not assumed absence.	ifc-power-ehs-2007, eirgrid-submarine-2022

Allocation rules · 3

Rule ID	Applies to	Rule	Source IDs
`allocation_direct`	Tasks and delivered objects	Use direct task/component metering first. If a campaign serves distinct objects, separate their measured quantities; allocate only irreducible shared work by a documented causal physical driver such as actual lift-hours, pulling time, vessel task-hours or serviced work volume. Shares are nonnegative and sum to one over all beneficiaries; explain standby/empty return. Route length alone is not an automatic allocator for dissimilar civil conditions or conductor configurations.	national-grid-overhead-2025, eirgrid-submarine-2022
`allocation_reuse`	Reusable machinery, formwork and temporary components	Keep one asset identity and manufacture boundary. When manufacture is included, attribute measured same-configuration mass/count multiplied by an evidenced dimensionless project share of total service; retain the public property. Maintain a cross-project/period/reuse ledger whose cumulative manufacture shares never exceed one. Unknown life or total service remains review; do not reset complete manufacture to every project. Site fuel/maintenance activities are separate and never reduced by the manufacture share.
`allocation_waste`	Scrap, excavated soil and recovered components	Waste export, supplier returns, internal reuse and a qualified recovered product have distinct gates. No automatic avoided-metal, avoided-fill or energy credit is applied. Keep collection/transport/treatment burdens and destination evidence; any separately justified recycling/substitution scenario states actual quality, recovery yield and counterfactual with independent review.	eirgrid-underground-2026, ifc-power-ehs-2007

Validation rules · 6

Rule ID	Applies to	Rule	Source IDs
`validation_object`	Reference object	Reject missing object ID, signed delivery state, defined endpoints/interfaces, actual geometry, configuration or relevant functional tests. One item is one complete declared object; do not use a service fee, cable mass or arbitrary work stage as its output. Different objects may not be compared without compatible function/configuration/boundary.	cpc3-explanatory-notes-2025, eirgrid-underground-2026
`validation_completeness`	Actual route/process inventory	Reconcile every actual drawing/BOM/work/utility/waste item to an atomic row and supplier/process boundary, including support, chambers/boxes, station structures, auxiliaries, railway/optical devices, temporary crossings and reinstatement. Baseline cards are conditional examples, never a universal complete BOM. Missing actual rows, unmeasured significant tasks, unknown shared denominators or unavailable upstream/treatment links remain incomplete/review; do not assert complete expanded lifecycle coverage.	eirgrid-underground-2026, itu-submarine-g971-2024, rdso-rail-ohe-2020
`validation_units`	Quantities and bases	All amounts must be finite, nonnegative and linked to real records for the same declared reference flow. Verify physical cable versus route length, count scope, same-state density/linear mass, fuel heating value, meter boundaries and gas/water/soil destination reconciliation. Do not infer fixed project mass, per-km intensity, concrete recipe, losses, demand or life. Record justified tolerances from actual instruments/specifications, not fabricated universal QA ranges.	eirgrid-underground-2026, eirgrid-submarine-2022
`validation_identity`	Selected public flow identities	Verify substance/material, fossil/biogenic origin, product/waste/elementary role, geography, route/state, primary property/unit group and compartment/subcompartment/timing before linking. Preserve exact public Chinese names and shared UUID/row IDs. A blank product reference identity remains the precise declared reference_line gap for this candidate; actual data must disclose every missing identity and dataset link. Neither an identity UUID nor a passed builder check approves methodology.
`validation_emissions`	Measured releases and environmental evidence	Reject inferred mandatory spill, SF6 leak or emission quantity from fuel/equipment presence. Molecular NO, NO2 and N2O and NOx-as-NO2 are different; immediate/outdoor and long-term/indoor are different; particle fractions must not overlap. Captured dust/slurry and treatment water are not direct environmental emissions. Missing quantified noise/habitat/marine coverage must be disclosed.	ifc-power-ehs-2007
`validation_acceptance`	Engineering and environmental acceptance	Use the actual applicable authority, project specification revision and test programme for this geography/AC-DC/optical/railway branch, with measured results and independent acceptance records. Sources here support process/method scope and give bounded examples; historic IFC/ITU/RDSO and another operator's numerical criteria are not current legal approval or automatic design compliance.	national-grid-overhead-2025, eirgrid-underground-2026, eirgrid-submarine-2022, itu-submarine-g971-2024, rdso-rail-ohe-2020
