BCA still expects **monthly CPD** via the **Electronic Productivity Submission System (ePSS)** — without gaps, without reconciliation spreadsheets, and without stopping when hardware is dismantled. This article explains **business continuity for Biometric Authentication Systems (BAS)** on Singapore construction sites: graded check-in modes, **XiD Mobile** (photo check-in, **1:1 face match**, **project geofencing**), and **CCTV + access-control sensor fusion** on **NVIDIA** edge — aligned with **SGBuildex** and the **May 2026 automated CPD** milestone. For platform context, see [BAS and ePSS for construction productivity](/blog/bas-and-epss-construction-productivity/) and our [SGBuildex × CPD 2026 briefing](/blog/xid-sgbuildex-cpd-2026/). ## Why business continuity matters for BAS vendors in Singapore BCA’s push toward **SGBuildex** and **automated Construction Productivity Data** makes continuity a procurement criterion. A biometric vendor is judged on whether productivity data **keeps flowing** when: - the main gate is dismantled in the tail-end phase, - only intermittent **4G** reaches the site office ([SIM routers for site security](/blog/sim-card-routers-construction-security/)), - workers move between **sub-zones** under one main contractor, or - a main contractor needs **one stream** into the national backbone while subs keep their own dashboards. If check-in stops when the turnstile leaves, the builder misses CPD months — and the **SGBuildex** integration story breaks down. That is why **business continuity** here means **uninterrupted, audit-grade attendance** across the **full project lifecycle**, not disaster recovery alone. ## One BCA project record — from permit to commence work to TOP/CSC In [App XiD Biometric ePSS SaaS](https://docs.xidtech.com/), each BCA-registered job is a **Project**, not a one-off gate installation. Workers enroll once; you can move them across **sites and access layers** (A → B → C → D) from one console — the same model on our [platform page](/platform/) and [biometric time attendance in Singapore](/blog/biometric-time-attendance-singapore/). **CPD is derived from attendance events**, not from “gate installed = project started.” When the last turnstile comes down, the project stays **open** until TOP/CSC reconciliation is done. That architectural choice is what makes **BAS business continuity** possible for **ePSS** and **SGBuildex-shaped** exports. ### Recommended handover as the construction site winds down | Phase | What happens on site | How XiD captures attendance | |-------|----------------------|------------------------------| | **1 — Full gates** | Turnstiles live on all entries | [RevoFace Neo](/products/revoface-neo/) + integrated readers (ZKTeco, HIK, Hanvon, …) | | **2 — Fewer gates** | Lanes consolidated | Retire devices in-console; workers routed to remaining gates | | **3 — Security post only** | No turnstile, still a checkpoint | Portable biometric station (+ [4G uplink](/blog/sim-card-routers-construction-security/) where needed) | | **4 — Internal / tail-end** | Gates gone; work continues inside | **XiD Mobile** — photo check-in, face match, geofence | | **5 — TOP / CSC** | Administrative close-out | Final CPD export; audit archive per retention policy | Overlap between phases matters: turn on the next mode **before** you remove the last gate, and you avoid a blank month in **Construction Productivity Data**. ## Check-in without turnstile — modes in production and what launches next Today, **180+ Singapore deployments** rely on a mix of: - **Turnstile and standalone terminal biometrics** — face and fingerprint, liveness where supported, OSDP/Wiegand to the gate. - **Multi-site, multi-gate** operation under one project. - **Portable stations** for temporary checkpoints. - **Supervisor-assisted mobile** with a mandatory audit trail (controlled fallback, not a replacement for worker biometrics). - **Offline buffering** on readers when 4G drops — logs sync when the link returns. Two layers complete **check-in without turnstile** for 2026: ### XiD Mobile — photo check-in, 1:1 face match, and project geofencing (launching soon) Built for the scenario regulators ask about: **no fixed BAS hardware on site**, but **CPD** must still count. 1. Worker captures a **live photo** at check-in and check-out. 2. **1:1 face match** against the same enrolled record used at the turnstile — one worker database, one identity. 3. **Liveness** on capture. 4. **Project geofence** — check-in is accepted only inside the approved site boundary; attempts outside the fence are **logged and flagged**, not silently booked as attendance. 5. Events enter the **same pipeline** as gate biometrics → **ePSS** → **SGBuildex-shaped CPD**. Mobile is not a parallel spreadsheet. It is **BAS business continuity** with the same audit bar as the gate. ### CCTV and access-control sensor fusion on NVIDIA edge (2026) Later in 2026 we add a fusion layer where **site CCTV** works with gate readers on **NVIDIA Jetson** edge infrastructure (the same family of compute as [RevoFace Neo](/products/revoface-neo/)): - **Backup** — when a turnstile is offline or removed, cameras at configured zones still contribute ingress/egress events, reconciled with project context. - **Enhancement** — while gates remain primary, fuse reader + camera signals for occupancy, tailgating cues, and zone visibility. Gate-first when hardware exists; camera-backed when it does not — one event store for reporting and **Construction Productivity Data**. ## SGBuildex, BCA, and the May 2026 CPD mandate XiD is listed as an **upcoming SGBuildex integration partner** under [Biometric Authentication Systems → Connected Solutions](https://www.dextech.ai/our-dexes/sgbuildex/sgbuildex-connected-solutions/). Our target: **schema-validated CPD pass-through by May 2026** for projects on App XiD — **connect once**, pass-through (not a data lake), lifecycle coverage from permit through TOP/CSC including mobile and CCTV continuity modes. If you are comparing **BAS vendors in Singapore**, ask: **will CPD still flow when my last gate leaves the site?** Read the full integration story in [XiD × SGBuildex — Ready for the May 2026 CPD Mandate](/blog/xid-sgbuildex-cpd-2026/). ## Technical reference — BCA check-in lifecycle and CPD continuity For a concise table of modes, compliance notes, and BCA survey alignment: **[BCA / SGBuildex — Check-in & CPD continuity](https://docs.xidtech.com/business-continuity/bca-check-in-and-cpd-continuity)** (Business Continuity on [docs.xidtech.com](https://docs.xidtech.com/)) ## Frequently asked questions ### What is business continuity for BAS on a Singapore construction site? It means **attendance and CPD keep flowing** when site layout changes — fewer gates, portable checkpoints, or **no turnstile** in the tail-end phase — using the same worker identity and project record from permit to **TOP/CSC**. ### Does XiD Mobile replace turnstile biometrics? No. **XiD Mobile** is a **continuity layer** when fixed hardware is impractical. Gate and terminal biometrics remain the primary capture where installed; mobile events use the **same 1:1 face match** and feed the **same CPD pipeline**. ### How does geofencing work for construction check-in? Check-in is accepted only inside the **approved project boundary**. Attempts outside the geofence are **logged and flagged** for audit — they are not silently counted as mandays for **ePSS** or **SGBuildex**. ### Will XiD support automated CPD for SGBuildex by May 2026? Yes — that is our published roadmap: **schema-validated CPD pass-through** for App XiD projects, with lifecycle modes (gate, portable, mobile, CCTV fusion) so data does not stop when gates are removed.
