The construction industry, known in French as BTP (Bâtiment et Travaux Publics), is a highly complex sector involving various actors, workflows, budgets, and resources. Managing a construction project means handling everything from human resources to equipment, schedules, materials, subcontractors, invoicing, safety compliance, and customer expectations. For many companies, especially small to medium-sized construction firms, the absence of a unified system results in inefficiencies, budget overruns, and operational silos.

Dolibarr ERP & CRM offers a modular and customizable open-source platform that can be tailored to the specific needs of the construction sector. This article explores how different Dolibarr modules can be implemented to streamline site tracking, project management, and resource optimization in the BTP field.

1. Understanding the Needs of Construction Companies

Before diving into modules, it's crucial to identify the core challenges faced by BTP companies:

• Real-time tracking of ongoing projects and construction sites

• Accurate resource planning (manpower, equipment, materials)

• Financial tracking (budget vs actual)

• Regulatory compliance and safety documentation

• Communication between the office and the field

• Integration of subcontractors and external teams

An ERP like Dolibarr can centralize and simplify these workflows while reducing administrative burdens.

2. Core Dolibarr Modules Relevant to Construction Management

Dolibarr's modular structure allows construction businesses to activate only the modules they need. Key core modules include:

• Projects: Manages overall project scope, deadlines, budgets, and milestones.

• Tasks: Enables breakdown of projects into specific tasks, assigned to users or teams.

• Timesheets: Logs working hours per employee or subcontractor on a given project or task.

• Third Parties: Stores details about clients, suppliers, subcontractors, and partners.

• Products/Services: Manages materials, tools, and services used in construction.

• Stock: Tracks inventory and equipment across warehouses and job sites.

• Invoicing: Generates quotes, invoices, and payment tracking.

• Expense Reports: Manages fuel, travel, accommodation, and other field expenses.

• Documents: Stores technical files, safety forms, blueprints, and compliance certificates.

3. Project Management: Structure, Phases, and Milestones

The "Projects" module is fundamental in construction. A project can represent a new building, renovation, roadwork, or civil engineering assignment. Within each project, companies can:

• Define start and end dates

• Link to clients, suppliers, and subcontractors

• Assign a project manager

• Associate documents like CAD drawings, permits, and inspection reports

• Track progress in real-time

• Link projects to quotes, invoices, and purchase orders

The integration with the "Tasks" module lets teams create Gantt-like structures and milestones (e.g., excavation, foundation, structure, finishing).

4. Workforce and Timesheet Tracking

A major challenge in BTP is human resource allocation. The "Timesheets" module offers the ability to:

• Track hours worked on each task or phase

• Attribute time to employees, contractors, or teams

• Link labor hours directly to project costs

• Identify delays due to understaffing or absenteeism

When combined with the "Leaves" module, managers can plan around vacations and optimize workforce scheduling.

5. Equipment and Material Resource Planning

Construction requires a vast amount of tools, vehicles, and consumables. Dolibarr's "Products/Services" and "Stock" modules help with:

• Managing tools (e.g., cranes, mixers, power tools) as products with serial tracking

• Monitoring material inventory (cement, wood, bricks, wiring)

• Generating alerts for restocking

• Allocating equipment per job site

• Tracking depreciation or maintenance schedules for machinery

6. Purchasing and Subcontractor Management

Most BTP companies rely on a mix of internal teams and external providers. Dolibarr's purchasing workflows support:

• Creating and sending supplier purchase orders

• Managing subcontractor agreements and billing

• Verifying deliveries and comparing to expected quantities

• Automating reorder levels for consumables

• Ensuring subcontractors submit safety and compliance documents before activation

The "Third Parties" module allows for customized categorization of subcontractors, including trade, availability, certifications, and location.

7. Budgeting and Financial Oversight

The financial aspect of construction is sensitive and requires tight control. With Dolibarr, BTP companies can:

• Prepare and manage detailed project budgets

• Track planned vs actual expenses in real-time

• Handle multi-stage billing (e.g., 30% upfront, 40% mid-project, 30% on delivery)

• Generate alerts for cost overruns

• Integrate with accounting modules or export to external systems

By linking expenses, purchase orders, and timesheets to specific projects, firms gain better financial transparency.

8. Field Data Capture and Mobile Access

Construction sites are dynamic environments. Through mobile-compatible interfaces and add-ons, Dolibarr enables:

• On-site time logging

• Uploading incident reports and site photos

• Digital signature collection

• Offline access to project documentation

• Mobile stock validation during equipment transfer

Some modules (e.g., MyDoli, DoliMobile) offer dedicated mobile interfaces for field agents.

9. Document Management and Regulatory Compliance

Compliance is critical in construction. Dolibarr's document management features allow for:

• Storing and categorizing safety files (PPSPS, risk analyses)

• Ensuring access to updated blueprints and construction notes

• Managing inspection reports and certifications

• Sharing documents with clients or inspectors via public links

Access permissions ensure that only authorized personnel can view or modify sensitive files.

10. Advanced Modules and Marketplace Extensions

Beyond core modules, Dolibarr has a vibrant ecosystem. On Dolistore and GitHub, you can find BTP-specific modules such as:

• ChantierPlus: Dedicated construction site tracking

• Planning: Visual staff and resource scheduling

• Multi-Warehouse Logistics: Track equipment across multiple storage sites

• Maintenance/Asset Lifecycle: Follow maintenance tasks on vehicles or machines

• Quality Control: Track non-conformities and corrective actions

Many integrators offer custom modules for activity reporting, safety tracking, BIM integration, or supplier evaluations.

11. Case Study: A Mid-Sized General Contractor

A construction company with 45 employees implemented Dolibarr to manage its residential and commercial projects. The process included:

• Setting up clients and projects with defined tasks and deliverables

• Using timesheets for daily labor input from mobile devices

• Managing equipment availability via stock and depreciation tracking

• Creating automated invoices based on progress reports

• Linking HR and project modules to plan around holidays

• Uploading site photos and incident reports daily

Within six months, they reported a 30% reduction in administrative workload, faster billing cycles, and better visibility into project health.

12. Benefits and Limitations

Benefits:

• Centralized project and resource management

• Cost-effective for SMEs in construction

• Modular activation avoids software bloat

• Real-time monitoring and field integration

• Integration with accounting and external tools

Limitations:

• Some BTP-specific features require paid modules or development

• Mobile apps vary in quality and may require customization

• Initial configuration can require consulting for best practices

13. Implementation Roadmap for Construction Firms

A step-by-step approach ensures smooth adoption:

• Step 1: Define business processes and priority pain points

• Step 2: Install Dolibarr and test core modules (Projects, Tasks, Third Parties, Products)

• Step 3: Add stock, timesheets, and invoicing features

• Step 4: Train users and create process templates (e.g., project start checklist)

• Step 5: Expand to mobile interfaces and integrate compliance tracking

• Step 6: Review performance quarterly and adjust configurations
