Taking off quantities top tips No. 2

When taking off quantities for Structural Metalwork using NRM 2, fittings may be billed as a calculated weight or as a percentage of the total weight of steelwork.

Best practice

What happens to weight percentage if revisions occur to the framed steelwork during site works ?

It is important if the percentage approach is adopted to fittings that the percentage is recalculated on completion of the project.

Billing structural metalwork

If a project is comprised of more than one steel framed structure, it is recommended that for clarity, they are billed separately.
