Metals estimating mistakes are one of the major reasons behind unexpected budget overruns in construction projects. When steel quantities, reinforcement bars, structural sections, or fabrication details are calculated incorrectly, it can lead to serious financial and operational issues. Underestimating metal requirements often causes material shortages, forcing contractors to place urgent orders at higher prices and delaying project timelines. On the other hand, overestimating results in excess procurement and wasted capital tied up in unused inventory.
