Bill of Materials & Material Take-Off Services
At IGI, we provide precise bill of materials drafting and material take-off creation for industrial and commercial projects. These documents are essential for planning, procurement, and fabrication, ensuring every part and material is accounted for before construction begins.
A Bill of Materials (BOM) outlines every component needed for a project, from raw materials to finished parts. A take-off translates those requirements directly from technical drawings into exact quantities. Together, they serve as the backbone of project planning – guiding purchasing, estimating costs, and keeping contractors aligned with design intent.
Errors in these documents can lead to shortages, over-ordering, or costly delays. Our drafting services provide accurate, construction-ready BOMs and take-offs that give project managers, fabricators, and contractors the clarity they need to deliver on time and on budget.
Understanding the Process
Our process starts by carefully reviewing design drawings, specifications, and client requirements. We extract every component, part, and material into a structured BOM, complete with descriptions, quantities, and sourcing details where applicable. For take-offs, we calculate material needs directly from scaled drawings, ensuring accuracy and traceability.
We deliver documents that are both easy to understand and detailed enough for procurement teams and fabricators. By standardizing formats and adhering to industry conventions, we make sure that all stakeholders from estimators to contractors can rely on a single consistent source of truth.
