Vision.A

An emergency response system for work at height on construction sites. Sensors on the worker, a mapped site and a visor for the rescuer, so that help reaches the injured person without losing time.

01 // WORK AT HEIGHT

Above two metres

Work at height is any job that exposes a worker to a fall of more than two metres: scaffolding, frameworks, roofs, ladders and aerial platforms. It calls for harnesses, helmets and lifelines, and for safety measures that prevent the fall.

Definition: Italian Legislative Decree 81/2008, art. 107.

02 // THE CASE STUDY

Eighteen kilometres of motorway

We took a real site: the widening of the A1 motorway between Barberino di Mugello and Calenzano, about 18 km of new carriageway, with viaducts and tunnels worked at height. On that site, around eighty workers are covered by two nurses.

Length of the works: Comune di Calenzano. Workers and nurses: from our interviews on site.

03 // THE RISKS

Height is not the only risk

Wind, rain and poor visibility take away footing and judgement. Fatigue and a lapse in attention slow reactions down. Equipment used in haste, or without proper training, turns a routine manoeuvre into a fall.

04 // THE INTERVIEWS

Talking to the site nurses

When someone falls, a chain of phone calls starts, and about fifteen minutes pass between the call and the rescue. We asked the nurses on site where that time goes.

  • Q

    Can nurses access the patient's clinical data?

    “Yes, we have access to all the clinical data of the patient, the worker, under Legislative Decree 196/2003 as amended by Legislative Decree 101/2018.”

  • Q

    How often does the construction site change?

    “Access points and call locations often change, and we are not always updated in time. Reaching the right location can take extra steps, and we lose critical time.”

  • Q

    How do you reach the patient?

    “There are two Defender ambulances on site, one as a backup. The 118 emergency service gives the coordinates, which are noted on a sheet of paper. From there the nurse drives from memory, if they know the site well, or types them into Google Maps on the phone.”

  • Q

    What if the nurse is late?

    Workers often try to help the injured person, and can make things worse. Each group has a safety officer to support the nurse, but that is often not enough for an effective response.

05 // THE SURVEY

What the nurses told us

We then asked the site nurses what a rescue system should do, and how they work today.

06 // THE SYSTEM

Who wears what

Vision.A connects three parts: sensors on the worker, a map of the site, and a helmet with a visor for the rescuer.

Worker

Shock and fall sensor, geolocation, health status detection.

Site

Construction site mapping, geolocation, navigation support for the ambulance.

Rescuer

Helmet with a visor, communication and navigation device.

07 // SITE MAPPING

A map that keeps up

A drone maps the site every two weeks, and LIDAR maps it on the spot; the light poles are already on site. On the 3D model, the injured worker has an exact position.

ResQ.Tag and ResQ.Vital

Two portable sensors for emergencies and impacts. ResQ.Tag, at the belt, detects a fall or an impact; ResQ.Vital, at the wrist, reads heart rate, blood oxygen and hydration.

09 // RESQ.HELMET

The rescuer's helmet

A smart safety helmet for rescuers on construction sites. Its visor gives immediate access to the worker's medical records, and guides the rescuer to the right spot.

10 // THE VISOR

Information over the site

The visor lays the data over the view of the site: a status bar, the 3D map, the emergency timer, the worker's parameters and the navigation. The rescuer controls it with gestures on the arm of the visor.

11 // VISION.APP

From an alert to a rescue

The app follows the same emergency on the phone: the alert and the call to 118, the route to the worker, their health data and medical record, and a map with every worker on site.

Vision.app screens: emergency alert, navigation to the worker, health status monitoring and charts, medical record
Vision.app screens: login, personal area, and a map showing where the workers are
