How are accessories typically taken off and priced?

Accessories in construction estimating are often taken off as a lump sum and priced per piece due to their distinct nature and variability. Accessories, such as hardware or specialized fittings, can vary widely in terms of cost and quantity based on the specific project requirements. By pricing them per piece, estimators can account for the actual number of items required, ensuring an accurate assessment of costs. This method provides flexibility and precision, allowing for adjustments based on the actual units needed on-site.

In contrast, other methods, such as pricing items by weight, area, or linear measurements, may not take into consideration the specific nature and value of individual accessories, leading to potential inaccuracies in the overall project cost estimation. For example, pricing accessories by weight could misrepresent their actual cost if the accessories are lightweight yet expensive, or if their usage does not correlate directly to a weight-based measurement.
