Bouygues: rollout across 200+ sites in 3 months

In construction, every day of delay on a site costs on average 1.5% of the total budget. Maintenance of machinery, concrete plants, and electrical installations is critical to meet deadlines.

The challenge: 200 sites, 8 regions, one single view

Bouygues operated with heterogeneous tools: paper forms on site, Excel at headquarters, local CMMS in some branches. Result: impossible to pool spare parts, duplicate interventions, uncontrolled overruns.

  • Interventions not tracked on 35% of equipment
  • Overstocking of parts in 8 regional warehouses
  • No consolidated visibility on maintenance costs
  • Breakdown response time: 4h on average

The MAINTEX response: centralize without rigidifying

Deployment of MAINTEX across all sites with the mobile app for site managers, integration with the group IS for consolidation, and field team training over 3 months.

  • Offline-first mobile app for isolated sites
  • Unified equipment catalog with photos and history
  • Standardized but adaptable intervention workflows
  • Dashboards by site, region, and group
The full story

How Bouygues deployed MAINTEX across 200 sites in 3 months

In the construction sector, managing maintenance and field operations represents a major challenge. Coordinating teams, tracking equipment, managing interventions, reporting incidents: these processes all require responsiveness, visibility, and standardization.

It is in this context that a major group like Bouygues launched a vast project to digitalize its field operations, with an ambitious target: deploy an operational management solution across more than 200 construction sites in just three months.

A strong need for centralization

Before the project, field teams used different tools depending on subsidiaries and sites: Excel files, WhatsApp exchanges, paper reports or isolated applications. This heterogeneity made the following difficult:

  • tracking interventions;
  • reporting anomalies;
  • steering equipment;
  • consolidating data at national level;
  • real-time visibility for project managers.

The group therefore wanted to roll out a single platform, accessible on mobile and easy to adopt by field teams.

A mobile-first approach tailored to the field

The choice fell on a solution designed for operational environments: use on smartphone and tablet, simplified operation, fast information reporting, and centralized dashboards.

Site teams could quickly:

  • create and track work orders;
  • report incidents in seconds;
  • schedule preventive maintenance;
  • monitor critical equipment;
  • assign interventions to technicians;
  • consult performance indicators in real time.

The main objective was clear: reduce processing times and improve coordination between head office and field teams.

A progressive but fast rollout

The project was structured in several phases to ensure fast adoption:

1. Pilot phase

A first wave of pilot sites made it possible to:

  • validate the processes;
  • adapt the business forms;
  • define the key indicators;
  • train operational champions.

2. Industrialization

Once adjustments were made, the rollout accelerated with:

  • standardized configuration templates;
  • short training sessions over video conference;
  • simplified documentation;
  • support for site supervisors and maintenance managers.

3. Generalization

In less than three months, more than 200 sites were operational on the platform with:

  • thousands of interventions tracked;
  • improved traceability;
  • centralized data;
  • consolidated visibility for management.

Immediate operational gains

The first results quickly confirmed the value of the project:

  • fewer informal exchanges;
  • better responsiveness on incidents;
  • more reliable equipment tracking;
  • standardization of practices;
  • improved reporting;
  • time savings for field teams.

Site managers now have indicators available in real time, making daily steering and decision-making easier.

A lasting transformation of site management

Beyond the simple digitalization, this type of project marks a deep evolution in working methods in the construction sector. Large groups now look for tools that can be deployed quickly, are simple to use on the field, and flexible enough to adapt to operational realities.

The success of a rollout across more than 200 sites in just a few months shows that a pragmatic, mobile-first and user-centric approach can considerably accelerate the digital transformation of field operations.
