Project-Based Production in Fabrication, Offsite Construction, and Shipyards: How BoQ-Driven ERP Unlocks Real Efficiency

In today’s era of accelerated timelines, tight budgets, and increasingly complex fabrication requirements, project-based production has become the dominant model across industries like shipbuilding, offsite construction, and heavy metal works. Unlike traditional batch manufacturing, project-based production is centered around unique, high-value deliverables, each governed by a Bill of Quantities (BoQ), cost control, and milestone-based planning.

This blog explores how this production model functions across sectors like shipyard workshops, modular construction facilities, and custom metal fabricators—and how ERP systems built around the BoQ, like ProjectVIEW ERP, help integrate operations, enhance control, and optimize every project from estimation to delivery.

What is Project-Based Production?

Project-based production (PBP) refers to a non-repetitive, engineer-to-order (ETO) or make-to-order (MTO) method where each job is custom-designed, costed, and delivered as a discrete project. It is widely used in:

• Shipyard Fabrication Shops: Steel hull components, piping, and structural assemblies produced to vessel-specific designs.
• Offsite Construction: Modular units, pre-cast panels, and MEP skids manufactured remotely and assembled onsite.
• Industrial Metal Fabrication: Bespoke stairs, frames, and steel components tailored to unique engineering drawings.

PBP requires a high level of integration between engineering, procurement, and production to track scope, cost, materials, and workforce across shifting project variables.

Challenges in Project-Based Fabrication Environments

• Constant scope and drawing revisions
• Multi-disciplinary coordination (steel, piping, electrical, painting)
• Difficulty in tracking BoQ items to actual cost and progress
• Lack of real-time visibility across fabrication units or project locations

Without a centralized system, teams rely on spreadsheets and disconnected planning tools—leading to errors, cost overruns, and missed deadlines.

The BoQ-Centric ERP Advantage

ProjectVIEW ERP was purpose-built for project-driven industries like ship repair, modular construction, and metal fabrication. At its core is the BoQ—the digital DNA of every project.

Here’s how it creates value:

• BoQ-Driven Estimation & Costing: Define work packages by measurable units, quantities, and resource breakdowns—improving accuracy and profitability.
• Integrated Procurement: Material requirements are linked to BoQ items, automating requisitions, tracking deliveries, and avoiding material shortages.
• Production Planning & Scheduling: Shop floor tasks are scheduled based on BoQ lines, with real-time tracking of labor hours, completion percentages, and work center loads.
• Progress & Billing Integration: As fabrication progresses, actual vs. planned metrics update dashboards, triggering milestone-based invoicing and performance reviews.
• Multi-Project Control: For shipyards or offsite factories handling multiple projects in parallel, ProjectVIEW provides visibility and control at both the project and enterprise level.

Seamless CAD Integration: TEKLA and Beyond

A critical enabler of BoQ accuracy and real-time project coordination is direct integration with leading engineering and CAD platforms like TEKLA Structures, AutoCAD, SolidWorks, and Revit. ProjectVIEW ERP supports seamless data exchange with these systems to:

• Automatically extract quantities, material lists, and drawing references into the ERP
• Maintain traceability between model revisions and fabrication tasks
• Eliminate manual data entry errors and speed up BoQ generation
• Keep engineering and production teams aligned on the latest approved versions

This integration not only reduces rework but ensures that the ERP is always working from the source of truth defined by the engineering model. For shipyards, the same applies to marine design tools such as AVEVA Marine, CADMATIC, NAPA, ShipConstructor and Maxsurf: see Shipyard Management Software & Shipbuilding ERP.

Real-World Example: Shipyard Steel Shop

In a shipyard steel fabrication unit, ProjectVIEW ERP can:

• • Capture the vessel-specific BoQ for steel works
  • Assign each part to drawing revisions and work orders
  • Track cutting, forming, welding, and assembly stages
  • Allocate labor and materials against each block or module
  • Integrate with QA/QC and issue traceable documentation packages
  • Sync directly with TEKLA Structures to reflect updated quantities and drawing modifications
