Guidelines for Reducing the Amount of Waste of Wood Materials in House Construction

Abstract

The residential construction project is expected to increase by an average of 10.0% per year or approximately 70,000 units per year during 2022-2024 as the real estate developers tend to increase the proportion of low-rise house construction, particularly in suburban areas to support purchasing needs for actual living. This is driven by the expansion of the government transportation network both the electric rail extension project and the motorway that connects travel between the suburbs and the city faster. The Home Builders Association states that house prices are likely to increase by 5-8% from April 2022 (Puttachard Lunkam, 2023).

The shutter board is a temporary wood structure to be installed as a model of concrete casting and reinforced concrete for the structure and components of the building, such as pillars, beams, floors, walls, roads, etc. The shutter board will support the weight of the concrete and create the boundaries for pouring concrete into the desired form as the material of an important cost for house construction. Consequently, reducing wood waste to a minimum in house construction is the management of construction costs for maximum efficiency and preserving the environment by reducing the amount of wood used.

This research is reducing waste of the shutter board from house construction by using the lean construction concept aimed; 1) to find the cause of wood waste from house construction, and 2) to study the guidelines for applying the lean construction concept to reduce the wood waste.
