While small time builders may prefer even to guesstimate the requirements, professional builders employ men to carry out the elaborate calculations. Planswift.com has launched the construction estimating software to help such builders in arriving at accurate estimates quickly and easily. The software is also an on screen takeoff tool to carry out various calculations on the layout. The architects and builders find it useful in accurately assessing the positions of objects like windows and doors. The carpet takeoff helps the builder in assessing the requirements for the flooring.
