Step-by-Step Guide to Quantity Takeoff for Steel Components in PEB Warehouses

When it comes to Pre-Engineered Building (PEB) warehouses in the Gulf, steel is the backbone. Columns, rafters, purlins, bracings, and cladding all come together to form the structure. But before a single bolt is tightened on-site, engineers and quantity surveyors must prepare an accurate quantity takeoff. Without it, procurement, fabrication, and cost control fall apart.

So, how do you approach steel quantity takeoff step by step?

Step 1: Study the drawings carefully. Begin with general arrangement and fabrication drawings. These highlight the size, spacing, and dimensions of each steel member. Misreading drawings is the first and most common error to avoid.

Step 2: Break components into categories. Group structural steel items into columns, rafters, purlins, girts, and bracings. Separate roofing and wall cladding sheets, as well as accessories like bolts, cleats, and gusset plates. Clear categorization avoids confusion later.

Step 3: Measure systematically. For columns and rafters, calculate lengths multiplied by section weights. For purlins and girts, measure running meters. For cladding, calculate surface areas of walls and roofs, adding allowances for overlaps. Precision here ensures accurate steel procurement.

Step 4: Cross-check with specifications. Always confirm material grades, thicknesses, and coatings. A mismatch between drawings and specifications can lead to procurement of the wrong material.

Step 5: Compile into BOQ. Organize the measured quantities into a structured BOQ with item descriptions, units, and totals. This makes tendering and cost estimation straightforward.

For Gulf engineers and surveyors, mastering this process saves time, reduces wastage, and keeps projects on track.
