The aim of this study is to determine the amount of construction waste (CW) based on the built area of buildings, in order to implement more effective monitoring and inspection of the generation and destination of the waste. A representative sample was chosen from buildings under construction in João Pessoa. A form to collect data on the characteristics and CW volume generation of the buildings was distributed. From the volume of CW discharged by the building companies, the weight was calculated based on a unit mass of 1025 kg m-3 . The results showed a generation rate of class A (CONAMA Resolution 307) CW of 86.27 kg m-2 . Also, for class A CW, a 90% confidence interval was calculated, with lower and upper limits of 62.31 and 136.02 kg m-2, respectively. Based on these results, the control of the generation and disposal of CW can be done by local authorities, indicating which sites are not following existing laws on the disposal of waste.
