Mão-de-Obra na Construção is an Android app developed by elizio fabiano that provides 10 tables with estimates for the main services required in a residential construction project. The tables include information on the number of labor hours required for services such as concrete work, water, sewage and gas installations, electrical work, ceramic floors and walls, roofing, wooden and aluminum frames, painting, plumbing, tiling, and other miscellaneous services. The app is free to use, and it is a useful tool for students of architecture, civil engineering, and construction technology. However, it should be noted that the estimates provided are only for reference purposes and should not be used as a substitute for actual quotes from professionals.

It is worth mentioning that the app will soon be removed from the Google Play Store, and users are advised to install the new version, Mão-de-Obra na Construção 2, which has a new layout and is lighter. The content of the new version is the same as the original and can be found by searching for "XDK MAODEOBRA" in the Google Play Store.
