Three things: which site a machine is on, whether site conditions crossed a line, and whether materials were signed out. It does not replace the whole construction suite.

Pain Points

  1. 01

    Crane and hoist locations are confirmed by phone

  2. 02

    Dust and noise breaches arrive as a notice from outside

  3. 03

    Material issues have no record at settlement

  4. 04

    Maintenance notes stay on personal phones

How the system is put together

Keep the equipment you have, connect the data first, then split the views by role. The connection layer takes the most work, and it is where most of our effort goes.

L1

Devices

  • Tower cranes
  • Dust and noise
  • Hoists
  • Distribution boxes
  • Video

PLCs, meters, access control, cameras and sensors already on site. Read what is readable, add a module where it is not, and leave the existing control system alone.

L2

Connection

Modbus · OPC UA · MQTT · HTTP · GB28181 · SDK

Common protocols connect directly. The gateway handles protocol mapping, local buffering and backfill, so the data does not break.

L3

Platform

  • Device registry
  • Time-series data
  • Alert rules
  • Work orders
  • Roles and audit

Device registry, time-series data, alert rules, work orders, roles and audit in one back end that serves several scenarios.

L4

Applications

  • Device-to-site map
  • Environment thresholds
  • Material checkout
  • Maintenance by device
  • Manager view
  • Phone actions on site
  • Narrow external lookup

Data is collected once and reused by every scenario added later, which is why the connection layer has to be done properly the first time.

What we deliver

01

Machine location

Key machines show their current project, and transfers are recorded.

02

Site conditions

Dust and noise notify the site when a line is crossed.

03

Material trail

Issues name the project and the use, for later settlement.

04

Maintenance on the asset

Service records stay on the machine across projects.

Where it fits

  • Building sites
  • Civil sites
  • Equipment hire
  • Project materials

What a real day looks like

Not a feature list: what actually happens in a day. These four steps are the common shape of such projects.

  1. 08:00 Dust over limit

    PM10 passes the limit, spray starts and the safety officer is notified.

  2. 08:20 Confirmed

    The officer uploads a photo and the record enters the environmental log.

  3. Monthly

    Exceedance windows export with the spray records for regulatory filing.

Delivery rhythm

Every stage has a checkable output. No six-month build followed by a single review.

  1. Week 1

    Site survey

    Walk the site, list devices, available ports and current systems, and mark what reads directly versus what needs a module.

  2. Week 2

    Pick the first scenario

    Rank the ideas by impact, feasibility and dependencies, then choose one that proves value without dragging in every department.

  3. Weeks 3-5

    Connect and wire up

    Gateways connect devices, data lands on the platform, and alert rules, roles and recipients are configured for a small internal group.

  4. Weeks 5-7

    Pilot

    One team or one building uses it for real; rules and screens change with feedback until false and missed alarms settle.

  5. Week 8

    Accept and repeat

    Check every acceptance item, finish documentation and training, then decide which buildings, lines or sites come next.

Acceptance is these three lines

The three items below come from projects of this kind and go into the acceptance sheet, instead of relying on a general impression.

  • task_alt

    Machine location does not need a phone call

  • task_alt

    The site hears a condition breach first

    Material issues match at settlement

Questions

Where does this industry get stuck?

Crane and hoist locations are confirmed by phone Dust and noise breaches arrive as a notice from outside Material issues have no record at settlement Maintenance notes stay on personal phones

What does Yifu do here?

Machine location: Key machines show their current project, and transfers are recorded. Site conditions: Dust and noise notify the site when a line is crossed. Material trail: Issues name the project and the use, for later settlement. Maintenance on the asset: Service records stay on the machine across projects.

What changes after it is in place?

Machine location does not need a phone call The site hears a condition breach first Material issues match at settlement

Do we have to replace our current systems?

No. The platform reads through interfaces or gateways and the existing systems stay in use. Only modules nobody maintains are worth replacing.

What does it cost, and how soon is it live?

Priced by scenarios and device connection points: a site survey produces the list, then a quote and schedule. Most projects have a first scenario live in four to eight weeks.
