Site safety tracking. Plant and tools accounted for.
For principal contractors, tier-ones and megaproject owners. We design RTLS for construction around site safety tracking, plant and tool tracking, workforce time-on-site and construction IoT locating — lone-worker, fall detection, mustering and induction-gated zones — hardware-agnostic across UWB, BLE, RFID and GNSS, framed for CDM and ISO 45001.
Construction: the use case, and the numbers it moves.
UWB where the site needs centimetre zones; BLE for workforce badges; RFID for tools and cribs; GNSS for plant between sites. Chosen for the programme, never sold.
1 · Account
Plant, tools and people are visible across every site in the programme.
2 · Protect
Lone-worker, fall detection and zone access fire in real time.
3 · Muster
Verified headcount at the muster point in seconds, not minutes.
What we keep seeing.
Plant and tools vanish between sites
Hired excavators, generators and calibrated tools move across compounds faster than the spreadsheet. Utilisation looks fine on paper while one site is short and another is overstocked — and tool loss writes off margin every month.
Time-on-site is an argument, not a record
Gate logs, paper inductions and radio calls disagree about who was where. Principal contractors need auditable time-on-site and zone presence for CDM duty-of-care, not a dispute after an incident.
Lone workers and falls are found too late
Roofers, plant operators and night crews work alone on changing footprints. Without fall detection, duress and a location that responders trust, minutes stretch while someone searches the wrong block.
The use cases that consistently pay back.
Plant & tool utilisation
See which machines and tools are on which site — cut idle hire and loss.
Workforce time-on-site
Inducted presence and zone time that stands up in a CDM audit.
Lone-worker & fall detection
Man-down, fall and duress with a location responders can use immediately.
Mustering & evacuation
Verified headcount at muster points in seconds across a live megaproject.
Site & zone access
Induction-gated geofences so the wrong trade is not in the wrong bay.
Heavy-equipment fleet view
GNSS and site RTLS together so plant movement between compounds is visible.
Hardware & software ecosystem
UWB and BLE safety platforms · active-RFID mustering · GPS field trackers · ruggedised and ATEX-rated tags where required — selected for your environment and safety case, never by price book.
Where we plug in
SAP · IBM Maximo · GIS / ADMS · permit-to-work and safety systems · SCADA-adjacent reporting · contractor-management platforms.
What good looks like.
What we design and document to
IEC 62443 (OT security) · ISO 45001 (occupational health & safety) · ATEX 2014/34/EU and IECEx where applicable · lone-worker standards (e.g. BS 8484) · permit-to-work alignment.
Where the payback shows up.
Substation outage safety
Contractor and lone-worker tracking with geofenced safety zones across a multi-substation outage programme.
Lone-worker SOS
Man-down and duress alerting with precise location for field technicians at remote sites.
Tool & equipment control
Test gear and switching equipment tracked across depots and substations, cutting loss and search time.
We had plant on three sites and no single view of utilisation, plus mustering that still ran on radio. TRACIO designed a vendor-neutral stack — RFID for tools, UWB for zones, GNSS for plant — around our CDM case. Muster dropped under a minute and tool loss stopped being a monthly write-off.
Solutions for this industry
Relevant case studies
Common use cases — what we keep seeing.
Multi-site plant utilisation
Problem: Hired plant sits idle on one compound while another site waits.
Tech mix: GNSS on plant, site geofences, hire/CMMS integration.
Outcome: Higher utilisation, fewer emergency hires, clearer off-hire decisions.
Tool crib & loss control
Problem: Calibrated and high-value tools walk between gangs and sites.
Tech mix: RFID cribs and portals, checkout rules, exception alerts.
Outcome: Lower loss, faster find-time, audit trail for calibration items.
Megaproject mustering
Problem: Manual roll-call fails when thousands are on a changing footprint.
Tech mix: UWB/BLE badges, muster geofences, live headcount board.
Outcome: Verified headcount in seconds; evidence for emergency drills.
Lone-worker & fall detection
Problem: Isolated work on roofs, plant and night shifts without reliable SOS location.
Tech mix: Wearables with fall/man-down, outdoor GNSS, indoor RTLS.
Outcome: Faster response, logged alerts, duty-of-care evidence.
Induction-gated zone access
Problem: Trades enter bays they are not inducted or permitted for.
Tech mix: Zone RTLS + induction/permit status from site systems.
Outcome: Soft or hard alerts, fewer near-misses, cleaner CDM records.
Workforce time-on-site
Problem: Gate data and supervisor counts disagree after an incident or claim.
Tech mix: Presence RTLS, access events, workforce system integration.
Outcome: Defensible time-on-site and zone history.
What buyers search for
Construction buyers researching locating usually start with safety and utilisation jobs:
- RTLS for construction — people, plant and tools on live sites — not a single-vendor box
- Site safety tracking — lone worker, fall detection, mustering, zone access
- Plant and tool tracking — utilisation, theft reduction, cross-site accountability
- Construction IoT locating — induction-gated geofences and time-on-site evidence
We stay services-led and vendor-neutral — locating architecture, integration and programme delivery, not a platform pitch.
Frequently asked questions
What is RTLS for construction used for?
RTLS for construction typically covers site safety tracking (lone worker, fall detection, mustering), plant and tool tracking across sites, and construction IoT locating for induction-gated zones. The stack mixes GNSS outdoors with UWB/BLE indoors or in dense structures, integrated to site access and HSE systems.
How do you track plant and tools across multiple construction sites?
UWB or BLE for high-accuracy zones on active sites, RFID for tools and store cribs, and GNSS for plant moving between sites. One programme design covers the mix — chosen for the site, never sold as a platform.
Can RTLS support lone-worker and fall detection on a live site?
Yes. Wearables with man-down / fall detection and duress, plus zone presence, mean a worker in trouble is located quickly — including alone on roofs, plant decks or remote compounds.
How does mustering work on a megaproject?
Tags and geofenced muster points give verified headcount in seconds instead of radio roll-call. Induction status and zone access sit alongside so you know who was authorised to be there.
Does this align with CDM and ISO 45001?
We design programmes against CDM duty-of-care and ISO 45001 evidence needs: presence, alerts, response and contractor accountability that you can show an auditor.
Will it integrate with our site systems?
Location and access events feed site access control, EHS, plant hire / CMMS and workforce systems so supervisors work in tools they already run.
