These adverse effects can be seen through the use of polluting materials, the massive volume of materials wasted, and the high rate of energy consumed at the construction site. Therefore, the construction sector requires sustainable methods. This shift will push the demand for reusable and recyclable building. Human behavior and occupant needs may change over time, affecting a building 's function. This will lead to demolishing many structures and dealing with energy consumption, unimagined volumes of waste materials, and expenditure on destroying and creating new buildings. Therefore, the environmental impacts of construction are not related only to the method of construction and job site activities. Also, the consequences of structural demolition are addressed. Hence, an assembly system is recommended by the National Research Council (NRC) to exploit the potential and advance the competitiveness and productivity of the U.S. construction industry in the next 20 years (National Academies Press, …show more content…
The idea of PTAS moderates traditional construction issues through intelligent assembly sequences and secured disassembly. The post-tensioned heavy timber (PTHV) can be disassembled in part or in whole to be reassembled again, and materials can be reused or remanufactured. It might be said that, in this post-tensioned building, materials are deposited in the building as long as the existing building desires, and then, it can adapt to the occupants ' needs and take on a new function or be recycled. The recycling possibility indicates the importance of environmental benefit of wood in heavy timber construction. Wood is a natural material that is vastly available and easy to be reproduced in temperate climate zones. Besides, wooden structures offer the opportunity to provide sustainable building through eco-friendly features and life cycle recycling. Wood has a very positive carbon footprint, and heavy-timber structures postpone releasing stored carbon in woods for decades or longer. These days, utilizing robotic fabrication techniques in timber construction provide a great flexibility and efficiency in wooden component production. This revolution can improve the economic and ecological use of timber. In historical times, the supply of wood was limited, and hard, manual labor accomplished the production of timber. Since robotic
