DEVB TC(W) No. 8/2025, Annex A 1.3 and 8
Smart construction management (SCM) in the DWSS
Smart construction management (SCM) is the DWSS data hub that collects and consolidates data from smart site applications, such as IoT devices, remote sensors, AI cameras and wearables, and sends real-time alerts to the responsible officers (DEVB TC(W) No. 8/2025, Annex A 1.3 and 8.1.2). Kodifly supplies it on SpatialSense, as part of a complete DWSS or plugged into a department's own DWSS.

What smart construction management is
The DWSS has three core components (Annex A 1.1.2). Workflow Management handles the six mandatory forms and records. Smart Document Management holds the formal project documents. Smart construction management is the third: the data hub for every smart site application deployed on site (1.3.1).
It monitors safety, progress, deformation, material, machinery and the environment (1.3.2). Where a contract adopts both the DWSS and the Smart Site Safety System, the 4S central management platform is amalgamated into the hub (paragraph 7, footnote 1). The devices that feed the hub are not part of the DWSS (paragraph 12, footnote 2).
Two ways a contract asks for it
Where the department runs its own DWSS, for example ArchSD, that system handles the workflow modules. Recent Hong Kong public works contract specifications then ask the contractor to supply the smart construction management hub and its AI. The contractor hands the Project Manager the website link and app universal link of each smart application for the department's DWSS, and its users perform all functions directly.
Where the department has no DWSS of its own, SpatialSense is both the DWSS and the smart construction management hub. Either way, Kodifly supplies the hub, the AI tool, the dashboards and the iCWP data feed.
What the SCM hub must do, clause by clause
Annex A of TC(W) No. 8/2025 sets the base. Contract specifications add the department link and the site network.
| Requirement | Source | SpatialSense |
|---|---|---|
| Data hub for IoT devices, remote sensors, AI applications and smart carry-on devices | Annex A 1.3.1 | Meets |
| Real-time alerts to responsible officers, by system email and app push | Annex A 8.1.2 | Meets |
| Web browser and native iOS and Android app | Annex A 1.6 | Meets |
| Website link and app universal link for each application, for the department's DWSS | Contract specifications | Meets |
| Original-format data fields. Photos and videos linked by path and metadata | Annex A 8.2.3, 8.2.4 | Meets |
| Data to iCWP by API within 24 hours, standardised to the Data Standardisation Report | Annex A 1.7.2 | Meets |
| Event records with photos, short videos, date, time, location, type, parties and description | Annex A 8.2.2 | Meets |
| Dashboards filtered by application, period, trade, location, users and severity | Annex A 8.3.1, 10.2.7 | Meets |
| Restricted-zone entries and Alert-Alarm-Action exceedances at deformation points | Annex A 8.3.2 | Meets |
| 4S platform amalgamated into the SCM, its cost carried in the SCM item | Footnote 1; contract specifications | Meets |
| 4G or Wi-Fi across the whole site, so app actions and photos sync at once | Contract specifications | Meets |
Smart applications the hub takes in
Annex A 8.2.1 gives six examples. The contractor proposes the applications and the employer's representative agrees them.
| Monitoring | Example application |
|---|---|
| Progress | Land-based and drone-based photogrammetry |
| Safety | AI cameras and wearables detecting danger-zone intrusion and unsafe behaviour |
| Deformation | Remote sensors for settlement, tilting, movement and vibration |
| Material | Sensors for early-age concrete strength by the maturity method |
| Machinery | AI cameras and IoT sensors for utilisation, unauthorised use and malfunction |
| Environment | Remote sensors for air quality, noise and water quality |
The AI tool inside the SCM
Annex A 1.5 asks for AI within the DWSS. Recent contract specifications set a baseline for an AI retrieval and reporting assistant. SpatialSense meets each line.

4S platform in the same hub
A sensor alert, opened from the DWSS.
A deformation sensor crosses its action level and the alert arrives. Readings show against alert, alarm and action levels, and the alert is acknowledged in the same place.
Smart construction management, answered
What is smart construction management in the DWSS?
One of the three core DWSS components. It is the data hub for smart site applications, with continuous monitoring and alerts to responsible staff (Annex A 1.1.2, 1.3.1).
Is the SCM the same as the DWSS?
No. The SCM is one component of the DWSS, beside Workflow Management and Smart Document Management (Annex A 1.1.2). Where a department runs its own DWSS, the contractor may supply only the SCM hub and its AI, plugged into that DWSS.
Are the sensors and cameras part of the SCM?
No. The hub collects their data, but the smart site applications do not form part of the DWSS, so their cost sits outside the DWSS estimate (paragraph 12, footnote 2).
How does the 4S platform relate to the SCM?
Where a contract adopts both the DWSS and the Smart Site Safety System, the 4S central management platform is amalgamated into the DWSS as one Smart Construction Management hub (paragraph 7, footnote 1). Contract specifications commonly carry the platform's cost in the SCM item.
How fast must SCM data reach iCWP?
Within 24 hours, by API or web services, standardised to the Data Standardisation Report (Annex A 1.7.2). The contractor also uploads the required data daily (11.1.5).
