1. Overview

Boilermaking Management turns Dolibarr into a genuine ERP/MES for boilermaking, piping, structural steelwork and welded fabrication companies. It covers the whole trade cycle, from the tender estimated on a cost-per-kilo basis through to the end-of-manufacturing file handed over to the customer and the notified body — with no external software.

The module ships twenty-six business objects, a purpose-built “steel and spark” dashboard, a workshop kanban, a load planning board, an EN 10204 traceability tree and sixteen situation reports exportable to CSV, Excel, Word and PDF. Every screen is translated into French, English, Spanish, Italian and German.

1.1 Target companies

·       Boilermaking and welded fabrication workshops (tanks, vessels, silos, hoppers, skids).

·       Industrial piping contractors working under EN 13480 or ASME B31.

·       Structural steelwork companies certified EN 1090 (EXC2 to EXC4).

·       Pressure equipment manufacturers working under CODAP, CODETI or the PED directive.

2. Business objects

Each object comes with a searchable list (multi-criteria filters, column selector, sorting, pagination) and a detail card with linked records, notes and history.

3. The “steel and spark” dashboard

The dashboard deliberately departs from the classic Dolibarr layout. Its palette — brushed steel greys shading into incandescent orange — echoes the trade itself: hot metal, welding arc and brass. Every tile is a link to the filtered list behind it.

3.1 Hero banner

·       Tonnage transformed during the current month.

·       Number of active business cases (won, in production, being erected).

·       Weld conformity rate computed from all recorded non-destructive tests.

·       Revenue booked during the current month.

3.2 Alert band

Alert	Meaning
Materials below threshold	Raw material references whose stock has fallen to or below their alert threshold.
Expired welder qualifications	Welders whose EN ISO 9606 certificate has lapsed; they are automatically suspended.
Qualifications to renew within 60 days	Prorogation window, configurable in the module settings.
Late work orders	Work orders past their planned end date and not yet completed.
Failed non-destructive tests	Inspections returned as non-conform, requiring joint rework.
Pressure tests to schedule	Hydraulic or pneumatic tests still pending.
Machine maintenance due	Preventive or statutory interventions reaching their planned date.
Obsolete drawings in circulation	Drawings whose revision index has been superseded.

 

3.3 Indicator zones

Workshop production: monthly and yearly tonnage, running and late work orders, workshop hours, material yield, scrap rate and valued work in progress.

Welding and quality: weld metres, active welders, qualifications expiring, weld conformity, open non-conformities, cost of non-quality, average margin and pending tests.

Material and equipment: raw material stock value, low-stock items, offcut value, machine availability, maintenance due and open sites.

3.4 Charts

·       Monthly tonnage produced over a rolling twelve months.

·       Tonnage split by material grade.

·       Load per machine measured from actual routing times.

·       Welding process split by weld metres.

·       NDT conformity rate per month.

·       Business cases by lifecycle status.

·       Top customers by revenue.

3.5 Workshop kanban and load planning

The kanban lays work orders out across the eight real manufacturing stages — preparation, cutting, forming, assembly, welding, inspection, finishing and shipped — each column showing the number of orders and the cumulated tonnage. Late orders are highlighted in red.

The planning page projects the weekly load over eight weeks, cross-references machine utilisation with actual routing hours and lists every late work order sorted by due date.

 

4. Reporting

A dedicated Reporting menu offers sixteen situation reports. Every report can be exported to CSV (semicolon separated), Excel, Word and PDF, or printed directly from the browser. Accented characters are preserved in every format.

5. EN 10204 traceability

The traceability page rebuilds, for any selected business case, the complete chain required by the end-of-manufacturing file:

·       Fabricated works with their mark, grade, thickness, mass and quantity.

·       Bill-of-material marks with designation, grade, thickness, quantity and total mass.

·       Material certificates with heat number, certificate type, steel mill, received mass, yield strength and assigned marks.

·       Weld joints with joint mark, process, position, weld length, passes and filler metal.

·       Non-destructive tests with method, inspection rate, result, defect count and report number.

·       Pressure tests with test type, test pressure, hold duration, result and report number.

Together with the drawings stored in the Dolibarr document manager, the WPS/WPQR records and the welder qualification certificates, this constitutes the documentation package handed over to the customer and to the notified body.

6. Native Dolibarr integration

7. Configuration

7.1 Business parameters

Parameter	Default	Purpose
Workshop hourly rate	62 EUR/h	Labour valuation used by the estimating engine.
Steel price per kilo	1.35 EUR/kg	Carbon-steel material cost baseline.
Stainless price per kilo	5.80 EUR/kg	Stainless material cost baseline.
Transformation coefficient	1.12	Uplift applied to raw material cost.
Scrap coefficient	1.14	Allowance for offcuts in the estimate.
Welder qualification alert	60 days	Lead time before an expiry raises an alert.
Default manufacturing standard	EN 1090	Pre-filled on new business cases.
Default NDT inspection rate	10 %	Pre-filled on new inspections.

 

7.2 Demonstration dataset

The configuration page carries two buttons. “Install demo data” fills the module with a realistic, fully cross-referenced dataset: business cases, estimates, works, drawings, bills of material, raw material, material certificates, offcuts, work orders, routing operations, cutting plans, weld joints, WPS/WPQR, welders, consumables, non-destructive tests, pressure tests, non-conformities, surface treatments, machines, maintenance, sites, HSE records, subcontracting, shipments and workshop staff — plus the customers and suppliers they refer to.

“Remove demo data” wipes the whole dataset, including the native Dolibarr third parties created for the demonstration, and cascades to records the user may have added under a demo parent, so no orphan row is left behind. The dataset is versioned, so an upgrade re-seeds an improved dataset instead of leaving stale demo content in place.

7.3 Permissions

Permissions are granted per functional group with read, write and delete granularity: business cases, design office, material, production, welding, quality, finishing, equipment, sites and HSE, purchasing and logistics, and staff — plus a reporting read permission and a module administration permission. Read and write are granted by default on activation so the module is immediately usable; delete and admin must be granted explicitly.
