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-b6850fdd0fa76349 quantitative
Qianhai Authority's tech arm 前海数科 has built a 3D digital twin of the district
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's own case study names the three parties and their roles: “自2015年起，由前海管理局牵头统筹、前海建投集团组织引导、前海数科研发实施” (“since 2015, coordinated by the Qianhai Authority, organised by the Qianhai Construction Investment Group, researched and implemented by Qianhai Digital City Technology”). The provincial department's page carries the same two companies as the report's authors: “深圳市前海建设投资控股集团有限公司 深圳市前海数字城市科技有限公司”. It describes the result as a city-level 3D spatial information model with BIM and GIS at its core, and states “前海数字孪生城市平台已建成” (“the Qianhai digital twin city platform has been built”).
Caveat
Qianhai Digital City Technology is the implementer rather than the sole builder: the same account puts the Qianhai Authority in the lead and the Qianhai Construction Investment Group in the organising role. The provincial department's page is no longer online and its wording was read from a web archive capture of July 2024.

Claim 2 clm-db911c66363e5ff3 quantitative
BIM models covering 193 km of municipal pipe networks, 6 km of utility tunnels, 50 km of roads and 600 buildings
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The provincial department's report lists the platform's contents as model quantities: “创建整合了…150个房建项目共600栋建筑三维模型、50公里市政道路BIM模型、9座桥梁BIM模型、193公里市政管网BIM模型、6公里综合管廊BIM模型” — 600 buildings from 150 building projects, 50 km of municipal road, 9 bridges, 193 km of municipal pipe network and 6 km of comprehensive utility tunnel, all as BIM models. ITS114 republished the identical sentence, crediting the provincial department as its source. The operator's own project page published three months later gives a materially different inventory for the same platform — “单体建筑模型296栋，市政道路43.3公里…综合管廊和地下管网227公里” (296 buildings, 43.3 km of municipal road, and utility tunnel and underground pipe network counted together as 227 km).
Caveat
No source says more than 600 buildings; the reports give exactly 600. The provincial page has since been taken down and both it and the ITS114 republication survive only as web archive captures, the ITS114 domain no longer resolving at all.

Claim 3 clm-00efaae1ecd8c5e3 descriptive
Live in the Guiwan, Qianwan and Mawan core areas
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The case study submitted to the 2024 China Smart City Conference states: “目前在前海核心区域——桂湾、前湾、妈湾片区运行完善” — the platform currently runs well in Qianhai's core areas of Guiwan, Qianwan and Mawan.
Caveat
Four months earlier the provincial department's report described the same three bays not as running but as the focus of work still under way — the platform was being built on top of the existing city-level BIM models. Neither account names a launch date or says what “running well” is measured by.

Claim 4 clm-beb4c7f3267231a5 descriptive
it feeds AI-assisted monitoring of facilities, traffic and energy
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The report says: “在基础设施运维方面将城市空间三维信息模型、城市运行数据以及人工智能等技术相结合，对前海区域的设施状态、资源、交通、能源情况进行实时三维可视化监测、智能分析、智能调度” — in infrastructure operation and maintenance it combines the 3D spatial model, city operating data and artificial intelligence for real-time visual monitoring, analysis and dispatch of facility status, resources, traffic and energy.
Caveat
This sentence stands in the chapter on the prospects for promoting the results (“成果市场推广应用前景分析”) and opens by saying Qianhai is about to move from full construction into the operating stage. It names no system, no start date and no measurement, and the report's own results chapter lists only models. The page is no longer online; the wording survives in a web archive capture.

Claim 5 clm-5ffd026b1ebdc910 quantitative
full 120 km² coverage is still pending
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The conference case study says the platform “即将覆盖至前海全域120平方公里范围” — it is about to cover the whole 120 square kilometres of Qianhai. The provincial report gives the area itself: a 2021 reform plan enlarged the cooperation zone “由14.92平方公里扩展至120.56平方公里”.
Caveat
The same case study elsewhere says the platform already “integrates model data for Qianhai's 120 square kilometres”, so the two statements describe coverage differently. No date is given for when the wider area is due.

Claim 6 clm-05b069b9243cae7c quantitative
Base model spans 15 km²
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The provincial report lists three base layers of the same size: “15平方公里的实景模型、15平方公里地质模型、15平方公里海底地形模型” (real-scene, geological and seabed-terrain models, each 15 km²). The operator's page describes the same foundation as “建立了覆盖15平方公里，涵盖规划、地质、地理（实景）三大基础信息模型” — three base information models covering 15 km².
Caveat
The two accounts name the three base layers differently: the provincial report lists real-scene, geological and seabed terrain, the operator lists planning, geological and geographic (real-scene). The 15 km² corresponds to the cooperation zone as it stood before the 2021 enlargement to 120.56 km².

Claim 7 clm-737d797017a590b0 quantitative
BIM inventory includes 193 km of pipe networks, 6 km of comprehensive utility tunnel, 50 km of roads, 9 bridges and 600 buildings
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The provincial report's results chapter gives exactly these quantities as models: “50公里市政道路BIM模型、9座桥梁BIM模型、193公里市政管网BIM模型、6公里综合管廊BIM模型”, alongside “150个房建项目共600栋建筑三维模型”, and puts the whole model library at “模型文件总体量约2TB”. ITS114 carries the same sentence. The operator's own page counts the same platform differently: 296 buildings, 43.3 km of municipal road, 9 landscape bridges, and 227 km for utility tunnel and underground pipe network together, with the model library given elsewhere as 1.38 TB.
Caveat
Sources say exactly 600 buildings, not more than 600. The same sentence also counts building projects twice over, as 150 in one clause and 49 in another. The provincial page has been taken down and its wording survives only in a web archive capture.

Claim 8 clm-9076e1f96c5aee91 descriptive
(self-reported by the platform operator, not independently audited)
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Every account of these figures traces back to the same two companies. The conference case study is bylined “深圳市前海建设投资控股集团有限公司” and “深圳市前海数字城市科技有限公司”, the same two names that head the provincial department's page, which files the text under a technology-achievements showcase and credits its own site as the source. No audit office, court, regulator or peer-reviewed study is cited anywhere in the record.
Caveat

Claim 9 clm-2bbb0ba4d8a11cf5 descriptive

Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The report's own results chapter measures the achievement in models rather than in built or instrumented assets: every headline quantity is written as a BIM model, and the chapter closes by sizing the whole delivery as a file library — “模型文件总体量约2TB” (total model file volume about 2 TB).
Caveat
The report does not say how much of the modelled network was built at the time of writing, and does not distinguish assets that exist from assets that are planned.

Claim 10 clm-968856da592d5a66 descriptive
which is not the same as a live sensor network, even when official language blurs the two
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The conference case study's account of what the platform does day to day is planning work: model integration, three-dimensional checks against planning limits, collision detection and scheme comparison. Where it does describe live data, the data feeds planning assessment tools rather than operations — “在三维仿真底盘上接入实时流量数据，建立片区活力、设施服务均好、交通可达等规划评估工具”. Its claim for operations is that the platform “强化了城市级统一监管，提升了城市安防与应急管理水平”, without naming a sensor network or a figure.
Caveat
The wider generalisation is this atlas's reading of the record rather than a statement made by the source.
