What is a key reason for requiring high accuracy in masonry estimates?

High accuracy in masonry estimates is crucial primarily because masonry typically represents a significant portion of total construction costs. Precise estimating enables contractors to budget effectively, ensuring that material and labor costs are accurately accounted for. By understanding the exact quantities needed for masonry work, construction teams can allocate resources efficiently and avoid financial overruns.

While the other aspects mentioned can contribute to project efficiency and effectiveness, they do not encapsulate the direct financial impact associated with inaccurate estimates in masonry work as clearly as the cost aspect does. The substantial investment in masonry materials and labor necessitates a thorough understanding to ensure that the project remains within budget and financially viable.
