Timber consumption for temporary works by buildings with the cast in situ reinforced concrete

Abstract

Building structures made of cast-in-place reinforced concrete use timber for formwork, struts, scaffolding, safety elements, and temporary construction site structures, which characterize the underutilization of biomaterial in a function of short life cycles and low added value. This work aims to survey timber consumption for temporary purposes in high-rise buildings with reinforced concrete structures cast in loco. Secondary data obtained through a systematic and exploratory review of national and international articles on timber use, reuse, and disposal was used. For studies with primary data for vertical housing buildings, timber consumption per constructed area ranged from 0.002 to 0.054 m³/m². For studies with secondary data and high-rise buildings for different uses, wood consumption ranged from 0.002 to 0.077 m ³ /m ² . There was variability in the results of 33 times (average), explained by the methods of quantification, applications, and reuse of the material.
