Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-6cf6610f556fc5fa descriptive
One of the earliest built-from-scratch smart cities, raised on reclaimed land at Incheon
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Cornell Tech case study documents Songdo IBD as a greenfield district built on reclaimed land beside Incheon and treats it as one of the founding examples of the tech-enabled new-town model. Deliberately hedged to 'one of the earliest' rather than a first-in-the-world superlative.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. The Atlas of Urban Tech, Cornell Tech — Songdo International Business District (research)
Claim 2 clm-af3cc84ea541b642 descriptive
wired with sensors from pneumatic waste pipes to traffic
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The case study describes the district's embedded infrastructure and states that the pneumatic waste system serves over 90% of buildings, processing roughly 97 tons of waste a day.
Caveat
No claim-specific caveat recorded

  1. The Atlas of Urban Tech, Cornell Tech — Songdo International Business District (research)
Claim 3 clm-9b8e89a537bb3c05 quantitative
The wider Songdo International City passed 232,000 residents by August 2026
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
IFEZ, the authority that governs the zone, publishes Songdo's population as 232,742 at reference date 31 August 2026 on its own statistics page, which it updates every two months. The claim names the area explicitly (the whole Songdo district, not the business-district core) and rounds down.

  1. IFEZ — Population statistics (authority)
Claim 4 clm-e01ed4f11f5b454a quantitative
the business district at its core had drawn about 70,000 residents and 33,000 jobs by 2023, roughly 65% of target
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The case study states the figure and the shortfall in one sentence, and is the only source found that reports the IBD core zone separately from the wider Songdo district. The percentage is the source's own, not calculated by us.
Caveat

Claim 5 clm-be446281514ad037 descriptive
IFEZ is now studying whether to shut the waste pipes down
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Both outlets reported on 27 November 2025 that IFEZ had commissioned a technical study on phased decommissioning of the automatic waste collection system. Both also record that IFEZ stresses no closure decision has been made — hence 'studying whether' rather than announcing a shutdown. Joongboo Ilbo reported on 24 August 2026 that the study is still under way and that IFEZ says its results cannot be applied uniformly across the zone — the review has not yet produced a decision.

  2. Dailian — IFEZ phased-decommissioning technical study (media)
  3. Joongboo Ilbo — Songdo waste pipes still under phased-closure study (media)
Claim 6 clm-a10df079036b0535 descriptive
Songdo's headline population counts the whole reclaimed city; the business district it was built around fills up far more slowly.
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
A comparison of the two figures the entry cites: IFEZ's 232,528 for the whole Songdo district against the case study's roughly 70,000 for the IBD core in 2023. No single passage states the comparison — a reviewer should check both numbers and the areas they cover.

Claim 7 clm-2b595891ae1525aa quantitative
the pneumatic waste network laid in 2005 and 2008
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Dailian names both years and both districts in one sentence; SBS reports the same installation dates for Songdo District 2 and District 4.

Claim 8 clm-29c9b097612b5f6c descriptive
is now a candidate for phased shutdown rather than a selling point
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
SBS reports the system is under closure review because of frequent breakdowns, excessive operating costs and odour complaints, with pipe corrosion among the facility problems.

Claim 9 clm-4d75ce6ef0d4c276 quantitative
the pneumatic waste system serves over 90% of buildings and handles about 97 tons a day, meeting 80% of its projected operational efficiencies
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The case study gives coverage, daily throughput and the share of projected efficiency the system achieved in one sentence.
Caveat
The case study does not say who measured these figures; they read as the operators' reporting, compiled by the researchers.

24 August 2026: IFEZ's phased-closure study of Songdo's pneumatic waste network is still under way; switching to door-to-door collection is being considered, and IFEZ says the result cannot be applied uniformly to Yeongjong and Cheongna.

  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
