SUPPLY CHAIN MANAGEMENT STRATEGIES FOR MULTI- STOREY TIMBER CONSTRUCTION IN AUSTRALIA AND NEW ZEALAND

摘要

Multi-storey non-residential buildings are a potential area that timber products could be used as structural elements. Two major barriers to timbers use in non-residential construction in Australia and New Zealand (NZ) have been identified as overall designer confidence and fire performance. Another important area that posses as a potential barrier to an increase in timbers use in multi-storey buildings is the current supply chain. Literature has outlined there historically hasn't been a market or demand for large timber buildings constructed over 4 storeys in Australia or NZ. As a result aspects of the supply chain needed to deliver such buildings have remained fragmented and relatively primitive in nature. The supply chain for multi-storey timber buildings in Australia and NZ includes a number of different stages as outlined below in figure 1. Between each stage a number of transportation, material and design information flows occur. This paper focuses on the issues in the supply chain from forestry through to construction and aims to outline the key areas that pose as a risk on the cost and time of multi-storey timber buildings. relatively new area in the construction industry. SCM views the entire supply chain instead of individual parts or processes. Its introduction has the potential to help improve transparency and alignment of the supply chains coordination and has the potential to improve time, cost and quality of construction. Time and cost are important factors that developers and clients alike typically use to measure the success of construction projects. For new building systems addressing things that have potential to impact these significant factors is crucial to its overall future success. This paper aims at reviewing the current state-of-art of SCM used in construction and discusses how it can best be adopted for multi-storey timber construction. The paper presents the results of semi-structured interviews with practitioners across the supply chain of timber construction in Australia and NZ to investigate the key problem areas and to identify opportunities. Case studies of timber buildings in NZ Finally the paper presents the SCM strategies that have been developed to address the current limitations and improvements in the timber industry.
