01
Incorrect mechanical estimates often miss important cost elements such as equipment, fittings, accessories, or installation labor. These missing costs can quickly increase overall project expenses and reduce profit margins.
02
Wrong quantity calculations or incomplete planning can lead to material shortages, labor scheduling issues, or delayed equipment delivery. These problems slow down mechanical installation and disrupt the entire construction schedule.
03
Inaccurate estimates may result in incorrect equipment sizing or improper system planning. This can affect system efficiency, performance, and long-term reliability after installation.
04
Poor estimating can cause over-ordering or under-ordering of mechanical materials. Excess materials increase waste, while shortages lead to work stoppages and reordering delays.
05
Failure to include code requirements, inspections, or compliance costs can result in failed inspections, rework, or project delays due to regulatory issues.
06
Budget overruns, delays, and system issues reduce client confidence and damage professional relationships, making it harder to secure future projects.
