# Construction and delivery of outdoor sport and recreation facilities

## 1. Scope and Applicability

Applies to complete accepted outdoor sport/recreation civil entities at actual sites: open-air football, baseball, rugby, athletics, tennis, car/bicycle/horse racing grounds; golf courses, beach installations, pleasure-boat marinas; public parks/gardens and zoological/botanical gardens. Independent indoor sport buildings, engineering services, material/equipment manufacture, operations and animal husbandry are not the reference product. Official scope is context; actual function/configuration/handover state establish identity. [un-cpc3-2025]

Sport surface/rootzone, living-plant establishment, animal containment and coastal recreation require selected construction routes tied to complete acceptance; material/road/building/harbour methods alone cannot replace the entity. Default scope is actual construction through declared final acceptance including contractual establishment/correction with consistent measured functional geometry/configuration. A square metre of turf or kilogram of materials cannot replace the whole category. No complete cradle-to-gate or whole-life claim is established.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.constructions-and-construction-services.constructions.outdoor-sport-and-recreation-facility-delivery |
| classification_refs | CPC 3.0 53270; context only, no accepted mapping implied |
| covered_products | Complete outdoor sport/racing, golf, beach, pleasure-marina, park/garden and zoological/botanical facilities with integral components |
| excluded_products | Independent indoor sport buildings, material/equipment manufacture, engineering services, operations/husbandry and separate transport harbour/waterworks/utility entities |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provide declared outdoor sport/recreation/garden/zoological-botanical display function and necessary access/containment through accepted entity |
| How much | One complete declared facility; measure type-specific field/track length-width, net playing/gross site areas, course zones, planting/enclosure, beach access and berth/water geometry; no assumed standard dimensions |
| How well | Actual contractual use/acceptance with as-built survey/layers/drainage/surface/establishment/containment/installation tests and correction evidence; no automatic certification/approval |
| How long or cycle | One actual construction-through-final-acceptance campaign including contractual establishment; no default operation years/life/renewal cycle |
| reference_flow_link | `finished_facility` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Accepted configured outdoor sport or recreation facility |
| 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 | site/perimeter/all functions; new/retained assets; measured original/as-built coordinates/datum/geometry; sport layers/track/zones; taxa/rootzones/establishment; zoo containment/life-support; beach access/protection/nourishment; berth/water/fixed-floating structures/salinity; equipment specifications; actual acceptance/establishment endpoint/dates; supply/transport interfaces; reuse ledger; material state/measurements; water receiver/contaminant tests; excluded stages |

item is the single-item display alias of public Item(s); 件 is the same count unit. All inventory/collection use per declared reference flow for the same actual accepted configuration. Geometry/function/quality qualify complete handover without facility mass, assumed loads, cost or life; missing qualifiers make a package incomplete.

Type-specific qualifiers apply to the declared configuration: document sport/course geometry for sport works, taxa/enclosures for actual gardens or zoo works, and marine/berth geometry only for actual beach/marina works. Mark each inapplicable qualifier with drawing/site evidence; this does not permit omitting an installed component.

## 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 | Exactly 1 item complete accepted facility, collected with cp_handover; all inventory/protocols per declared reference flow. |
| physical_records | materials and geometry | Mass; Volume; Area; Length; Number of items | kg; m3; m2; m; item | Measured/certified deliveries/geometry; volume/area-to-mass needs same-material/state measured density/areal mass, no invented facility mass. Number of items/item applies to live planting materials garden_tree and garden_shrub under cp_plant; retain actual species, specification and counted quantity. Mass/kg, volume/m3, area/m2 and length/m apply only to matching native quantities. Convert only with measured applicable evidence; do not force living plants into mass or geometry. |
| energy_property | electricity and diesel | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66`; Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | MJ; kg | Electricity MJ, metered kWh times 3.6; diesel kg, volume-to-mass needs batch density. Property coefficients are not physical density/heat content. |
| cable_length | `cable` | Length `838aaa23-0117-11db-92e3-0800200c9a66` | m | Preserve public Length/m; reconcile installed/cut/return length, never rewrite to Mass. |
| water_state | water interfaces | Volume `93a60a56-a3c8-22da-a746-0800200c9a66`; Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | m3; kg | Conserve volume ledger separately; sea-resource primary Mass/kg needs weighing or supported same-salinity/temperature density, discharge Volume/m3; constituents separate. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Surveyed preconstruction site/vegetation/soil/water/retained assets, actual material/assembly gates and transport origins |
| starting_condition_role | foreground_start |
| product_classification_scope | Complete declared outdoor sport/recreation entity with integral installations; classification does not replace function judgment |
| recursive_input_rule | Retained facility is starting stock; independently acquired completed works use bounded upstream links, no self-output recursion/assumed historic burden reconstruction |
| upstream_dataset_requirement | Independently verify supplied state/process/geography/property-unit/manufacture-transport boundaries of materials/components/utilities/equipment/separate works; disclose gaps |
| disclosure | Onsite construction through final acceptance; upstream coverage/operation/renewal/demolition separate, no complete cradle-to-gate or whole-life claim |

| rule_id | Rule | source_ids |
| --- | --- | --- |
| b_delivery | Include actual preparation, selected drainage/surfaces/planting/structures/installations, utilities/logistics/testing/correction through declared final acceptance including contractual establishment. Select the real complete configuration and evidence absent alternatives. | un-cpc3-2025; cedd-landscape-2026; se-natural-2025 |
| b_consumed_inputs | All purchased input rows retain actual attributable consumption, including damage, rejects, cutoffs and replacements before final acceptance. Local installed/applied/planted wording identifies intended route/configuration and has this explicit exception for consumed pre-installation or establishment losses; it does not restrict inputs to successful installation. In native units reconcile gross attributable receipts + opening stock - verified returns/transfers - closing reusable stock, keeping installed/accepted quantities and actual waste separate. Preserve exact supplied state and assembly boundaries; do not add embedded constituents again.  The stock-consumption equation applies to consumed materials/components, not to manufacturing-share rows under cp_reuse. In particular excavator_capital and timber_formwork retain actual asset mass times their supported conserved manufacture share under c_share even when the physical asset is returned, transferred or held as reusable closing stock; keep physical movements separate and never charge both full consumed manufacture and a share for the same asset. | |
| b_supplied_state | Material and assembly manufacture are separate upstream links at actual supplied gates. Onsite concrete batching, soil stabilization, hydroseeding, rubber mixing, welding/coating need actual ingredients/equipment/releases separately; do not charge complete purchased assembly plus its embodied ingredients. | se-artificial-2013; cedd-landscape-2026 |
| b_interfaces | Integral works count once. Independent complete building/road/harbour/pipeline/cable works need bounded upstream interfaces; their methods may inform components but do not replace complete recreation-facility methodology. Retained assets are starting stock. | un-cpc3-2025; epa-marina-2001 |
| b_environment | Separate supply/abstraction/discharge/treatment liquid and waste sediment/plume. Actual contaminants, infill losses, chemical releases and soil/land-use carbon require evidence and individual rows. Noise/vibration/habitat/occupation need independently bounded assessment; unmeasured is not zero. | epa-marina-2001; epa-heavy-construction-1995 |
| b_later | Default excludes post-acceptance sport/visitor/boat operation, husbandry, routine irrigation/mowing/fertilizing, maintenance dredging, future surface/plant/equipment replacements and demolition. Extensions need actual time/activity/replacement/removal/destination inventory without default life. Pre-acceptance establishment/removal/rework included. | cedd-landscape-2026; epa-marina-2001; defra-zoo-2012 |
| b_extensions | Cards are specific candidate routes, not every facility BOM. Before dataset completeness, cover all actual sports/racing/golf/park/garden/beach/zoo/botanical/marina requirements; add each other taxon, surface/marking/joint material, civil assembly, equipment, chemical, packaging, waste and release atomically. UUID gaps cannot justify scope narrowing. | un-cpc3-2025; se-artificial-2013; defra-zoo-2012 |

| logistics | Logistics and reusable construction assets | conditional | Actual external transport or explicitly included manufacture module | foreground_process | per declared reference flow |
| handover | Testing, correction, cleanup and accepted output | required | One complete actual facility with final acceptance endpoint | reference_process | per declared reference flow |

Utilities/water/releases are tagged to actual tasks once in support. Conditional exchanges receive amounts only on occurrence; non-applicability requires evidence. Named taxa/materials do not restrict the category; actual alternatives require separate verified rows.

###### Perennial ryegrass seed (Lolium perenne) (`grass_seed`)

Only actual separately supplied ryegrass seed; record cultivar, purity, germination and application. Separately purchased seeds of other taxa and inputs actually mixed onsite require their own rows, with real mixing activity retained. A purchased preblended seed mixture instead requires one row for that actual supplied mixture with supplier composition, batch and upstream mixing/supply boundary; its embedded seed species are composition evidence, not additional purchased input rows. Separately added seed outside the purchased mixture remains an extra exchange. No compulsory one-species route is assumed.

###### Artificial grass carpet (`artificial_carpet`)

Only an actual supplied synthetic carpet assembly with independently verified supplier bill of materials, fibre/backing composition, pile, measured areal mass and installation/cutting records. Confirm whether infill, adhesive and shockpad are included or separately supplied, and count each component once. Verify the physical supplier and assembly inclusion scope independently. Performance, safety and service-life claims used in modelling require evidence for the actual product and conditions; no universal duration or safety/non-toxic promise is assumed. This synthetic assembly cannot substitute for living planting stock.

Independently verify supplier mineral composition, actual production route, dry/moist state, particle grading/purity, surface-compatible specification and real loading/return records. Determine the actual processing steps from supplier evidence. Any accepted particle envelope, narrower project grading and dosage require physical evidence; no default envelope or dosage is prescribed. Keep this infill exchange separate from drainage/rootzone sand.

| v_coverage | Report checks, findings, omissions and measurement/identity/route/stage coverage separately. Upstream links do not make this whole-life/complete cradle-to-gate/comparative-equivalence methodology; technical candidate checks grant neither scientific approval nor publication. | un-cpc3-2025 |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Foreground construction/accepted facility entity record |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Matched site/function/configuration and declared construction-delivery boundary; full life requires independent evidenced upstream/downstream stages |
| excluded_use | Unqualified full-life/complete cradle-to-gate/comparative equivalence; operational/husbandry service; assumed mass/life/recipe/certification/legal approval |
| required_metadata | Reference measured geometry/configuration; all routes/tasks; supply/transport; dates/acceptance/establishment; taxa/material states; grid/voltage; water resource/receiver; ledger/protocols; reuse shares; external links |
| required_quality_disclosure | Measured/modelled evidence/uncertainty/identity-range gaps; route/stage coverage; uncharacterized noise/habitat/land carbon/water contamination/missing releases; scientific review governed by metadata |
| update_trigger | Changed function/site/configuration/layers/taxa/supply/acceptance-establishment/water receiver/reuse denominator or new actual evidence/identity |
