puts response.read_bodyGet Construction Details
Retrieves the full details of a specific construction by its unique identifier. A construction is a composite building element (e.g. a facade wall) made up of one or more EPD-backed materials, with aggregated LCIA (Life Cycle Impact Assessment) results across lifecycle modules.
Endpoint
GET {{epdbaseUrl}}/construction/:id
Path Variables
| Variable | Type | Required | Description |
|---|---|---|---|
id | UUID (string) | ✅ Yes | The unique identifier of the construction to retrieve. Example: 9b1fc6c6-e08d-45b2-9d4f-df8d99bad066 |
Authentication
This endpoint requires a Bearer token passed in the Authorization header.
Authorization: Bearer {{BearerToken}}
Obtain a token via the Authenticate user request and store it in the BearerToken environment variable.
Response
200 OK
Returns a JSON object representing the construction and its aggregated lifecycle impact data.
Top-Level Fields
| Field | Type | Description |
|---|---|---|
id | string (UUID) | The public unique identifier of the construction |
internalId | string (UUID) | Internal system identifier |
internalVersionNumber | integer | Numeric version of the internal record |
internalVersion | string | Semantic version string (e.g. "0.0.0") |
name | string | Display name of the construction (e.g. "Skousbo facadevæg, træ") |

expectedLifespan | integer | Expected service life in years (e.g. 50) |
tenantId | string (UUID) | ID of the tenant that owns this construction |
tenantName | string | Display name of the owning tenant |
newestVersion | boolean | Whether this is the latest version of the record |
createdAt | string (ISO 8601) | Timestamp of creation |
lastModifiedAt | string | null | Timestamp of last modification, or null if never modified |
dataSourceId | string | null | ID of the data source, if applicable |
datasourceName | string | Name of the data source |
declarationOwnerName | string | Name of the declaration owner |
basedOnMaterialIds | string[] | IDs of base materials this construction is derived from |
epdInfo | object | null | EPD-specific metadata, if applicable |
transportationInfo | object | null | Transportation scenario data, if applicable |
declaredUnit Object
Describes the functional unit used for the LCIA calculations.
| Field | Type | Description |
|---|---|---|
declaredUnit | integer | Enum value for the declared unit type |
declaredValue | number | Quantity of the declared unit |
baseEpdDeclaredUnitType | integer | Base EPD unit type enum |
baseMassUnitType | integer | Base mass unit type enum |
baseDeclaredMassValue | number | null | Mass value, if applicable |
mass | number | null | Mass of the construction |
massUnit | integer | Unit enum for mass |
lciaResults Array
An array of lifecycle impact assessment results, one entry per lifecycle module.
| Field | Type | Description |
|---|---|---|
moduleTypeEnum | integer | Identifies the lifecycle module (e.g. 0 = A1-A3, 1 = A4, 15 = C3, 17 = D) |
moduleStatusEnum | integer | Status of the module result (e.g. 2 = calculated) |
indicators | array | List of environmental impact indicator results for this module |
indicators item fields:
| Field | Type | Description |
|---|---|---|
type | integer | Enum identifying the indicator (e.g. 12 = GWP total, 1 = ODP, 6 = PENRT) |
unit | string | Unit of measurement (e.g. "kg CO₂ eq.", "MJ", "mol H+ eq.") |
value | number | Calculated impact value (may be negative for biogenic carbon or module D credits) |
originalIdentifier | string | Original identifier string from the source data |
constructionEpds Array
The individual EPD components that make up this construction.
| Field | Type | Description |
|---|---|---|
id | string (UUID) | Unique ID of the construction EPD entry |
name | string | Display name of the component material/EPD |
index | integer | null | Ordering index within the construction |
parentConstruction | object | null | Reference to a parent construction, if nested |
epd | object | Full EPD object for this component (same structure as a material EPD) |
Notes
- Negative values in
lciaResultsare expected and represent biogenic carbon storage (e.g. in timber) or net benefits in module D (beyond system boundary). - The
moduleTypeEnumvalues map to standard EN 15978 lifecycle modules. Common values:0= A1–A3,1= A4,2= A5,3= B,5= C1,14= C2,15= C3,17= D,16= C4,4= B4. - The
typefield inindicatorsis an enum — refer to the indicator type reference in the API documentation for the full mapping. - Tenant-scoped constructions will only be returned if the authenticated user belongs to the owning tenant.
