In the realm of steel structure construction, efficiency and precision are key to success. The Advance Bill of Materials (ABM) plays a pivotal role in ensuring smooth project execution and cost management. Let's explore what an Advance BOM is, its significance, and how it benefits the construction industry.
Understanding Advance Bill of Materials (ABM)
The Advance Bill of Materials (ABM) is a simply “Listing of total steel required” to finish the whole steel structure in advance. Generally, after “initial member addition, we need to submit “ABM report” to client. By generating the ABM report in SDS/2 or tekla structures.
Key Components of Advance Bill of Material
- Materials and Specifications: The BOM specifies the types of materials needed (e.g., steel sections, plates, bolts) and their exact specifications (e.g., grade, size, thickness).
- Quantities: It includes precise quantities of each item required for the entire project or specific phases, ensuring accurate procurement and cost estimation.
- Assembly Details: For complex structures, the BOM may include assembly instructions or sequences.

Importance of Advance ABM in Steel Structures
- Precision and Accuracy: By detailing every component and its specifications, the Advance BOM minimizes errors in procurement and fabrication, ensuring that the right materials are used in the right quantities.
- Cost Management: It helps in estimating project costs more accurately by providing a clear breakdown of materials and quantities required.
- Efficiency in Procurement: With a well-defined BOM, procurement teams can streamline the purchasing process, reducing lead times and potential delays.
ABM Tekla Structure
Every member gets “Page-Line” no. & after ABM generation client can procure the required material. Generally, client always ask ABM report for “Main steel only” i.e., for Beam, column, braces etc. But if your structures consist of miscellaneous members of WF, channel, HSS etc. then in that case client ask for ABM for Misc. member also.

Which profiles are considered in ABM?
Following profiles are considered while preparation of the ABM in steel detailing.
- W profiles
- HSS profiles
- Channel profile
- Angle
- And plates (per customer requirement; 1 1/2" and above thickness plate not available in market)
No project can take off successfully without proper planning. Most times, Patron's struggle to get the right requirements in place and this delays the whole project. The ABM mark also appears on the Bill of Materials to ensure there is no wastage of ordered material.
Conclusion
The ABM plays a crucial role in the steel detailing process as it serves as a foundation for accurate material take-offs, cost estimation, procurement, fabrication, and construction planning.
