Quantity takeoff

Quantity takeoffs (QTO) are precise estimates of the materials and labor costs required to finish a construction project. During the pre-construction phase, an estimator prepares them, breaking down the project into smaller, more manageable parts that are easier to evaluate. These measurements are used to prepare a construction scope bid. Estimators examine the drawings, specifications, and models to figure out different quantities and their costs. Since, the components, their quantity, and price are all included in the model, quantity take-off can be done automatically using Building Information Modelling (BIM). The time taken for completing a construction project can be reduced by the use of quantity takeoff. These takeoffs are also called material takeoffs and construction takeoffs.

A weight, with an unknown mass, falls through a distance of 10 millimeters (mm) onto a collar attached to the bottom end of a vertical bar. The bar is 3 meters (m) long and has a cross-sectional area of 600 square millimeters (mm2). The impact causes the bar to instantly stretch by 2 mm. The Young's modulus of the bar material is 200,000 MPa. Determine: 1. The weight of the falling object. 2. The stress experienced by the bar due to the impact.
