Construction: site safety tracking, with plant and tools accounted for.
For principal contractors, tier-ones and megaproject owners. We design construction site tracking around worker safety, 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. Advice first. We can also supply, lease and install the complete system.
We reply within one working day with questions or a written price. No obligation. Fixed-scope engagements from £3k. Prefer to talk? Book a free 30-minute call.

How is tracking used in construction? On construction sites, tracking (GNSS, BLE, RFID and indoor RTLS where needed) keeps plant, tools and people visible across every site in the programme. Lone-worker, fall detection and zone access alerts fire in real time, induction-gated geofences keep the wrong trade out of the wrong bay, and muster points give a verified headcount in seconds, not minutes. Time-on-site becomes an auditable CDM record.
How it works in Construction.
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.
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.
Common problems we find.
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 money 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.
Construction use cases we design for.
Plant and hired equipment used and off hired on time
Owned and hired plant shows its site and recent use, so idle items are moved or off hired. Usually telematics from the manufacturer or GNSS trackers, confirmed in the survey.
Equipment leaving the compound out of hours
Tagged equipment leaving out of hours raises an alert for your security team to check. Usually GNSS trackers with a geofence, confirmed in the survey.
Light equipment and power tools across sites
Breakers, lasers, generators and pumps show their last known site or van. Usually BLE tags or LoRaWAN in yards, confirmed in the survey.
Lifting equipment and harnesses in date
Items past their thorough examination or inspection date are stopped at issue. Pre-use checks stay. Usually passive RFID or 2D codes, confirmed in the survey.
Materials found before the lift
Steel, precast and pallets are scanned on arrival and placement, so crews see the bay before the crane slot. Usually 2D codes or passive RFID, confirmed in the survey.
More construction use cases.
- Site store tools: tools issued from the site store and returned.
- Collision avoidance: plant and pedestrian proximity alerts that support existing safety measures and don't replace them.
- Lone workers: an alarm someone can act on when a person working alone needs help, alongside your lone working procedure.
- Mustering: a headcount at muster points to support your roll call, which stays.
- Site zones: entry to work zones checked against site induction.
- Time on site: time on site records, with a lawful basis and worker consultation first.

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 you gain
Plant utilisation you can see
Hired and owned plant report where they are and whether they are working, across every compound. Measured as utilisation per machine, emergency hires and days on hire while idle.
Less time searching for tools
Calibrated and high-value tools are checked out and located between gangs and sites. Measured as find-time, tool losses and calibration items overdue.
Faster mustering with a live headcount
On a changing footprint, the muster board shows who is on site and who has not reached a muster point. Measured as time to a verified headcount in drills.
Lone workers reached sooner
Fall and man-down alerts arrive with a location, indoors and out. Measured as alert-to-response time.
Zone access tied to induction
Entry to bays and zones is checked against induction and permit status. Measured as uninducted entries and near-misses per zone.
Time-on-site records that hold up
Presence and zone history replace disputed gate counts after an incident or claim. Measured as time to answer a claim or incident query.
Who else sells into construction locating and what programmes get wrong.
Sites are pitched Hilti ON!Track-class and Bosch Track & Trace tool systems, Milwaukee/DeWalt brand Bluetooth ecosystems, mixed-fleet trackers (MapTrack and peers), plant telematics, and high-precision RTLS for larger indoor works. Brand-locked tool apps fail on mixed subcontractors. Warehouse UWB playbooks fail on muddy, moving sites.
What programmes get wrong: buying a single OEM tool cloud when three trades share the gate; separating lone-worker safety from plant utilisation; skipping induction-gated geofences; and expecting GNSS-only accountability inside structures. Independent design blends BLE/RFID tool events, selective RTLS, telematics and mustering under one operating model, without selling the tags or plant hardware.
Prioritise safety and utilisation KPIs that commercial and EHS already argue about, then pick radios per zone. TRACIO scopes that architecture and the integration to induction, time-on-site and maintenance records.
Multi-contractor gates make identity the hard problem. A locating design that only works for the principal contractor’s branded tools will be bypassed by subcontractors within a week. Prefer open tag strategies, induction-linked badges and plant telematics that can share zone events with the principal’s EHS and commercial systems without forcing every trade onto one consumer app.
Weather, temporary power and moving boundaries mean RF surveys must be repeated as the site evolves. A one-shot warehouse-style survey is not enough. Tie mustering and lone-worker alerts to the same identity layer as tool and plant accountability so emergency response and utilisation reporting do not maintain parallel truth.
Plant and workforce locating on large construction sites.
Heavy-equipment OEMs and major contractors (including fleets and job sites associated with Caterpillar, JCB, Komatsu and large civils primes) increasingly specify mustering, plant utilisation and zone control. Named brands here illustrate the market, not TRACIO clients.
How an engagement works in construction.
Stages, with a gate after each
- Scoping call: 30 minutes with our specialists; a written proposal with the price if there is a fit.
- Discovery & business case: use cases, KPIs and technology direction (typically 1 to 5 days on site).
- Supplier selection: requirements, shortlist, RFP and TCO (typically 3 to 6 weeks).
- Pilot: judged against pass/fail criteria written before any equipment goes in (with timings agreed per site).
- Rollout & handover: scoped per project, phased by site or wave.
What we need from you
- A named sponsor who can sign off each gate
- An operations lead and an IT/OT contact for a few hours a week
- Site drawings, floor plans and process maps
- Access to your site access control, induction records and plant-hire or CMMS data
- Site inductions and access to the live footprint as it changes
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.
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.
What does a construction engagement cost?
It depends on scope and the number of sites. Every engagement is scoped per project and priced in writing before work starts: £3k to £30k per project, or £1,200 a day. Regional ranges for Europe, North America and other regions are on how we work. Extra sites, on-site RF survey and integration into more than one system of record add to the scope. Hardware and licences are extra: buy them direct from the supplier, or have us supply them as a separate, optional service, priced openly.
How long does a construction engagement take?
Discovery usually takes 1 to 5 days on site, supplier selection typically 3 to 6 weeks and a pilot with timings agreed per site, with a gate after each. Rollout is scoped per project. The build programme sets the window: a pilot needs a phase that runs long enough to measure.
What if the pilot fails?
It stops at the gate. The pilot is judged against written pass/fail criteria agreed before any equipment goes in, so a fail is a clear result, not an argument. You pay no rollout costs and keep the artefacts from each stage: requirements, scored shortlist, TCO, RFP pack, pilot criteria and the measured results. Pilot equipment can be rented, so there is no capex to write off.
Do we need to consult the works council or employees before tracking people?
Usually, yes. Locating people is processing personal data, so under UK and EU GDPR you need a lawful basis, normally a data protection impact assessment, and clear limits on purpose: safety and mustering, not performance monitoring. Where you have a works council or recognised employee representatives, involve them before the pilot.
In Germany the works council has a co-determination right over systems that can monitor staff. We design for this from the start: zone-level presence rather than continuous tracks where that is enough, pseudonymised IDs, short retention and role-based access. See GDPR and RTLS.
Who owns the data, and can we avoid supplier lock-in?
You own it. Your data and IP stay yours, with full export. During supplier selection we put data export, open APIs and exit terms into the RFP and contract, so you can change supplier later without starting again.
