KISCON / construction work ledger (KISCON)

Record type: Construction work ledger PDF extracts

Official access: KISCON official portal · Ledger notification service linked by KISCON

Roles: Contractors report ledger particulars to the owner. KISCON retains and provides the ledger information. The 2023 report identifies CIIC as the operator; this institutional attribution reflects that report. The owner named in the R3 records is the Wonju Regional Construction Management Administration; being a system operator does not make an organization a construction participant.

Collection method: The seven R3 ledger PDFs were obtained from KISCON on request, as confirmed by the author. Other users may request records for specified construction works by submitting an official letter to KISCON. Access through this procedure does not establish permission to redistribute the PDFs; they are retained research inputs and are not redistributed in this supplement.

Identifiers, dates, and scope: R3 ledger IDs: 1103643, 1161045, 1284971, 1411152, 1559005, 1688411, 1930079. Keep installment and whole-work amounts and dates, notification and confirmation information, print time, and revision number distinct. The common initial contract and commencement dates are 13 and 30 July 2018, respectively.

Application: Observed ledger evidence: R3 only.

CALS / Ministry of Land, Infrastructure and Transport (CALS_WORK)

Record type: Work information and records of the facilities delivered

Official access: CALS construction management system · CALS public information portal

Roles: MOLIT agencies and contracted site users supply work information; CALS makes it available. KICT is identified on the system service page. Record contributors, the system service provider, and the owner of each work have distinct roles.

Collection method: The work information was collected from the public system website; the study uses the retained information and comparison material. No new comprehensive candidate search is claimed.

Identifiers, dates, and scope: R1: C2002061, Seongnam–Janghowon section 2. R3: C2018023, Jeongseon–Bukmyeon. CALS identifiers refer to CALS records, not to all contributing records. R3 outcomes are Banjeom Bridge, Yeoryang Bridge, and Yeoryang Tunnel.

Application: Work information for R1 and R3; CALS is a source used in the applications, not the defining source of every WorkRecord. For R3, the retained comparisons associate records by work title, route, section, and owner but do not establish uniqueness within a documented CALS candidate set. The combined R3 view is conditional on this cross-system correspondence.

CALS / road-management offices (CALS_REGISTER)

Record type: Facility registers, original-work fields, inspection plans, and inspection-history records

Official access: CALS facility-maintenance scope

Roles: The system provides entries maintained by the relevant road-management office. The records name Suwon in R1, Nonsan in R2, and Chungju in R4. These facility-management roles are distinct from the roles of the system operator and the party performing the inspection.

Collection method: Public CALS records are retained as source information, transcriptions, and tables of inspection plans and inspection-history records. Source query dates and event dates are kept separate.

Identifiers, dates, and scope: R1 register fcno values end in BAF46991E054B099289CEB28 and BAF56991E054B099289CEB28; both record a completion date of 31 December 2013. R2 fcno: 1B08F838AB8B6FD7E054B099289CEB28, Route 4. R4 fcno: F18C7A6BC1343A7DE044B099289CEB28, Route 19. R2 has 17 plans and 17 inspection-history records, not 34 completed inspections.

Application: In R1, the assignment of construction-stage rows to register entries distinguished by direction remains unresolved; the R2 and R4 Mungok bridges are separate structures.

FMS / Korea Authority of Land & Infrastructure Safety (FMS)

Record type: Facility identification and dated safety and performance assessment information

Official access: FMS official portal · FMS service responsibilities

Roles: KALIS operates the system, and MOLIT provides oversight. Retain the managing-agency labels in each record separately from the identities of the operator and the party performing the assessment.

Collection method: Public facility-management records were collected from the system website. The retained R1 extract records a collection date of 27 August 2026 and an information date of 30 June 2026.

Identifiers, dates, and scope: R1: TU2014-0000019 and TU2014-0000020, Baekma road tunnels. Latest recorded safety and performance assessments: 28 November 2024, grade A. A railway tunnel with the same name is excluded from that correspondence. The next-assessment date is a scheduled date.

Application: Dated R1 condition snapshots; neither a complete life-cycle history nor an FMS history for R3 is implied.

Wonju Regional Construction Management Administration (NOTICES)

Record type: Separate management-service tender and award notices

Official access: 9 May 2018 tender notice · 25 May 2018 award notice

Roles: The Wonju administration issued and posted the notices and is the procuring agency. The listed engineering firms are service participants. Electronic bidding through G2B does not mean that the research copy was collected from G2B.

Collection method: The records were collected from the issuing agency's public website, and the retained tender and award PDFs were inspected.

Identifiers, dates, and scope: Tender notice: 9 May 2018, Notice 2018-038, page 1. Award notice: 25 May 2018, a separate record, page 1; Kunhwa 43%, Soosung Engineering 37%, Donghae Engineering 20%. Both name the Route 42 Jeongseon–Bukmyeon work; neither provides a KISCON or CALS identifier.

Application: R3 management-service and participation information; not a construction-contract instrument.

Seumter / building administration (SEUMTER)

Record type: Building permit, commencement report, and building register

Official access: Official permit and commencement services · Official register issuance service

Roles: Applicants submit administrative documents; the competent local authority handles permits and register administration; Seumter provides the national service under MOLIT. The 2023 report identifies Korea Real Estate Board as the delegated operator. No case-specific issuing authority is assigned without a record.

Collection method: No building application records were observed or collected for B01; the manuscript includes only the modeled source types.

Identifiers, dates, and scope: PermitRecord, CommencementRecord, and the building-related use of StructureRegisterRecord retain distinct meanings. A road-work start date in CALS is not treated as a building commencement report.

Application: Modeled and unpopulated: B01.

CEMS / Korea Association of Construction Engineering & Management (CEMS)

Record type: Engineering-service registration and performance information

Official access: Official service-contract reporting guidance

Roles: Service businesses submit information, and the relevant administrative agencies approve it or issue notifications; the association supports the management of engineering-service information. These institutional roles do not identify any R3 participant.

Collection method: Institutional context is drawn from the 2023 report and system guidance. The empirical service evidence for R3 consists of the Wonju notices, not a presumed CEMS extract.

Identifiers, dates, and scope: No R3 CEMS record identifier is assigned.

Application: Institutional source context only.

CALS quality-test records / CQR (QUALITY)

Record type: Two quality-test certificates

Official access: CALS quality-test access service

Roles: CQR is the testing agency recorded on the certificates; Chungju is the recorded owner, and Jeongjin is the contractor. CALS provides access but does not perform the tests.

Collection method: Public CALS certificate information is retained in the research material, with a recorded retrieval date of 31 August 2026.

Identifiers, dates, and scope: R4 certificates 20231214888 and 20231214889 were issued on 12 December 2023; the sampling locations are lanes 1 and 2 of the Mungok Bridge–Munsan Interchange segment.

Application: Later pavement work supported by segment-level evidence, without establishing bridge-only treatment or a separate maintenance contract.

This study (STUDY)

Record type: Integrated information representations and record associations

Roles: The study defines IntegratedWorkData and RecordMapping. Source agencies retain authorship of and responsibility for their own records.

Collection method: The collected records are organized using construction works and their relationships with physical structures as references. A correspondence established through record comparison is distinct from a cross-reference stored in an original record.

Identifiers, dates, and scope: IntegratedWorkData → hasMapping → RecordMapping → sourceRecord → SourceRecord; represents points to ConstructionWork. Scope and evidence remain attached to each association.

Application: A study-defined structure; application instances are maintained outside the public documentation package.

MOLIT and CIIC, 2023 (REPORT2023)

Record type: Study on the integrated construction industry information platform

Roles: An institutional and integration-planning reference cited in the manuscript; proposed shared work references do not establish the existence of a currently operating service.

Collection method: The retained 2023 report; not a channel for collecting application records.

Identifiers, dates, and scope: Institutional context in 2023, shared work information, and work–service–structure relationships. Case evidence comes from the individual records collected.

Application: Institutional design basis, not evidence of case identity.
