How to Calculate Labour and Consumable Costs for Aluminium & Glass Works in Oman and GCC

In aluminium and glass works, materials may take the spotlight, but labour and consumables often decide whether your estimate is realistic or not. In the GCC market, clients expect precision, and even small miscalculations can eat into profit margins. Let’s walk through the basics.

Labour CostsLabour productivity in Oman and other GCC countries is usually calculated in man-hours or man-days. For example, installing a square meter of curtain wall or a running meter of aluminium frame comes with a standard productivity rate. These rates vary depending on complexity, access conditions, and project type. To estimate correctly, multiply the total quantity (sqm or Rm) by the productivity rate, then convert into man-hours. Finally, apply the local wage structure to arrive at the labour cost.

Consumable CostsConsumables include sealants, screws, anchors, foam tapes, gaskets, and protective films. These are easy to miss but essential for both functionality and durability. For example, a façade may need multiple sealant cartridges per square meter of glass. Always link consumables to the corresponding item—like sealant per sqm of glazing or screws per running meter of frame.

Key Tips for Accuracy

• Use GCC-specific productivity norms rather than generic ones.

• Include allowances for overtime, supervision, and site conditions.

• Cross-check consumable consumption rates with supplier data.

• Don’t forget wastage factors, especially for sealants and gaskets.

Getting these calculations right makes your estimate competitive while protecting project margins.
