# Institutional, hospitality and other non-residential building delivery

## 1. Scope and Applicability

This PCR covers physically constructed, accepted non-residential buildings for public entertainment, accommodation and restaurants, education/libraries/archives/museums, healthcare including veterinary care, indoor sport/recreation, conventions, religious use, prisons, law courts/parliament, communications and residual non-residential farm uses, consistent with the occupancy boundary in un-cpc-3-53129. It covers the entire declared delivered entity rather than only one easier school or hospital route. Construction services, supplied material packages, commercial office/retail/warehouse/transport-terminal buildings, industrial factories, agricultural storage buildings/silos, residential/community residences, mines, power/chemical plants, other specialized industrial facilities and outdoor sport installations are excluded. Physical farm shelters other than industrial/storage facilities remain eligible according to documented predominant use. Mixed-use sites require a declared building and shared-system scope; a classification label alone proves no methodology applicability.

Actual designs may use reinforced/cast-in-place or precast concrete, steel, timber, masonry or combined construction. Each applies through evidenced project work packages. Fixed services and fit-out must reflect the real delivered function: e.g. air/pressure/cleanliness systems in healthcare, teaching/laboratory spaces, hotel sanitation, kitchen exhaust, auditorium acoustics and long-span indoor sport roofs, secure institutional installations or communications infrastructure when actually delivered. These are applicability prompts, not mandatory generic equipment recipes or design thresholds. Owner business equipment, movable furniture, medical machines, broadcast/IT equipment and later occupant fit-out are separately disclosed exclusions unless the declared entity includes them with distinct inventories.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.constructions-and-construction-services.constructions.institutional-hospitality-and-other-building-delivery |
| classification_refs | CPC 3.0 53129 — Other non-residential buildings |
| covered_products | Complete accepted institutional, hospitality and residual non-residential building entities of the stated occupancy classes |
| excluded_products | Residential, industrial/storage, commercial-office/retail and specialized civil facilities; services and material kits; undeclared operating equipment |
| representative_product | One actual accepted building of a documented occupancy/configuration, not a hypothetical class-average building |
| production_route | Actual preparation, foundations/structure, envelope/fit-out, fixed services, testing and handover, with route-specific work packages |
| market_state | Installed at declared site and accepted in the declared complete handover condition |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Deliver the declared structure, enclosure, fit-out and fixed systems for the documented non-residential function |
| How much | One complete accepted building; record measured gross/internal/useful floor areas with named measurement convention, levels, height, footprint and actual function-specific capacity with units |
| How well | Actual as-built configuration and project performance/acceptance records, including delivered fit-out and excluded equipment; no assumed load, compliance or approval |
| How long or cycle | One construction-to-handover event with actual dates; no operating duration or service-life default |
| reference_flow_link | reference_building |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Completed institutional, hospitality or other non-residential building |
| 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/country; building identifier; predominant use and mixed-use partitions; actual delivery dates/state; measured area definition and geometry; structural system; functional capacity and actual performance criteria; accepted shell/fit-out/fixed-service scope; excluded equipment; actual work packages; retained prior structures; upstream gates and missing links |

The unit item is the count abbreviation of public Item(s), not kg, m2 or m3. Areas and capacities characterize function/configuration; they do not silently rescale the reference entity. Shell-only or phased delivery must disclose its incompleteness and cannot be compared as a fully fitted delivered building.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_entity | reference_building | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | item | One accepted building is 1 item; use cp_handover to bind the whole configuration and measured geometry. No invented building mass. |
| geometry_scope | glazing; roof_membrane | Area `93a60a56-a3c8-19da-a746-0800200c9a66` | m2 | Measure actual supplied surface; distinguish gross, net, overlaps and losses in cp_materials. Area numerators are exchanges per the same entity, not a new functional unit. |
| energy_basis | lv_electricity; mv_electricity; diesel | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Retain public energy property and group. Electricity conversion is 3.6 MJ/kWh; diesel conversion requires actual mass or volume, density and LHV evidence in cp_site, never a generic engine consumption rate. |
| volume_state | plywood; tap_water; groundwater; river_water; ready_mix | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 | Use physical volume at documented state. If tickets are in mass, use measured/source-supported density for the same material/moisture/temperature and preserve raw values; no building-volume-to-count or standard-water-density default. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Recorded actual site before project works and construction products/components at expressly identified supply gates |
| starting_condition_role | foreground_starting_point |
| product_classification_scope | Delivered non-residential entity of the inclusions/exclusions above; site services are not the product |
| recursive_input_rule | A retained/reused building or shell is taken once at its received state, with inherited burden and additional works disclosed; do not recursively rebuild an already supplied same-category entity |
| upstream_dataset_requirement | Link compatible material/component manufacture separately and actual transport from named origin/gate; check installed-component and upstream scope to avoid duplicates. Missing links prevent complete cradle-to-handover claims |
| disclosure | Actual preparation, construction, commissioning and waste routes; upstream links; pre-existing demolition; excluded later occupation, maintenance/replacement, final demolition/treatment and beyond-boundary benefits |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| construction_boundary | dataset | Collect actual site excavation/backfill, foundation work, erection, envelope/partitions/finishes, fixed-service installation, lifting, welding/bolting, curing, testing/retests and acceptance, plus temporary facilities and waste transfer. Off-site material/equipment manufacture is upstream, not automatically site foreground. This alone is neither complete cradle-to-gate nor whole-life LCA. | rics-wlca-2024 |
| actual_route | all inventory rows | Flow cards are atomic applicability seeds, not a fixed bill. Include every actual used component, coating, joint, chemical, fuel, packaging and waste in separate rows using the same reference, collection and evidence rules. Record route absences with evidence; unresolved identities must not exclude a real route or omit burdens. | jrc-levels-boq-2021; un-cpc-3-53129 |
| water_emissions | utilities; waste | Distinguish product supply, natural withdrawal, reuse loops, dewatering and contained treatment-bound liquids. Direct released constituents, air species and receiving compartments require actual evidence; noise/vibration and land effects must be assessed with activity, location and duration records, and unavailable exchange identities/characterization disclosed rather than invented universal emissions. | epa-concrete-washout-2012; epa-construction-dust-2010 |
| transport_split | dataset | Keep manufacture, actual inbound transport, site movement, waste export and treatment as identified modules; retain route distance, payload and empty trips from cp_transport. Add mode-specific atomic freight services using matched providers. Fuel embodied in a transport service must not be duplicated as site fuel; no default distance. | rics-wlca-2024 |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| shared_site | dataset | Subdivide work packages and directly meter/trace attributable material, energy and waste first. If unavoidable, document the physical causal driver for each shared activity (machine hours, supplied quantities or actual service demand). Area alone is not an automatic driver for unlike hospital, theatre or hotel systems. Unproven relationships stay under review; economic allocation needs justification and sensitivity. | ghg-allocation-2011 |
| asset_conservation | temporary | Keep an asset-specific cumulative ledger across projects, periods and reuse. Use project activity divided by an evidence-backed compatible total service/activity basis to allocate manufacturing burden; the cumulative attributed shares cannot exceed one. Retain unused share and supported lifetime/activity estimates; unknown total basis remains review. Do not copy RICS illustrative reuse counts/lifetimes or reset a full manufacturing burden at each site. | rics-wlca-2024 |
| waste_recovery | waste | A waste export is not a coproduct credit. Document separation, receiver, treatment and whether a traded recovered product actually exists. Keep recycling assumptions and beyond-boundary substitution separate; no automatic avoided-primary credit or double accounting of supplied recycled material. | ghg-allocation-2011 |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| reference_aggregation | all inventory rows | Sum only attributable actual exchanges over the declared construction/acceptance event; retain each exchange numerator unit per declared reference flow. Reference output remains 1 item. Reconcile opening/closing stocks, returns, installed quantities and actual losses; internal stage transfers are not new external purchases. | cp_materials; cp_site; cp_waste; cp_handover | row quantity per declared reference flow | jrc-levels-boq-2021 |
| conversion_evidence | lv_electricity; mv_electricity; diesel; plywood; ready_mix | Convert electricity kWh to MJ by the exact 3.6 factor.

| direct_release | fossil_co2; nitrogen_dioxide; pm10 | Retain measured release mass; if calculated, document actual matched activity times a separately evidenced substance/device/medium-specific factor and control basis. Leave missing species/factors inconclusive, not zero; no mandatory factor is prescribed by this PCR. | cp_emissions; cp_site | kg of actual substance per declared reference flow | epa-construction-dust-2010; rics-wlca-2024 |
| supported_asset_share | excavator_share; crane_share; plywood | Assign only a supported project share following asset_conservation; preserve numerator activity, compatible total basis and all previous shares. Unknown basis is a review gap and must remain disclosed. | cp_assets | attributed burden per declared reference flow | rics-wlca-2024 |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| identity_state | all inventory rows | Exact material/species, supply/waste state, assembly scope and real public property/unit; no forced identity by name | supplier and raw identity/measurement records |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| entity_gate | reference_building | Reject missing entity configuration, measured geometry, named area convention, documented function/capacity, handover status/dates or scope exclusions; compare only equivalent delivered functions and stage scopes. | un-cpc-3-53129 |
| inventory_gate | all inventory rows | Check atomic identities, public Chinese names, direction/type, actual reference properties/units, route conditions and duplicate assembly components; unconfirmed UUID remains explicit, never implies absent burden. | jrc-levels-boq-2021 |
| records_gate | dataset | Every actual exchange needs traceable collection and same-reference aggregation, actual geometry/conversion evidence and stage completeness. Unknown emission speciation, asset allocation basis or upstream/treatment link remains inconclusive for affected claims; no assumed zero. | rics-wlca-2024; ghg-allocation-2011 |
| handover_gate | handover | Check actual commissioning/retest records against project requirements and delivered systems. Absence of a required installed system cannot be hidden by another occupancy route; construction-to-handover check does not validate future service life or operational performance. | gsa-commissioning-2020 |
