    Development of a multiple-criteria decision assessment framework for adaptive reuse case study building selection
    (31/10/2017) Yakubu, E; Egbelakin, T; Rasheed, E; Mbachu, J; Shahzad, W
    A number of theoretical methodologies for the selection of best adaptive reuse alternatives have been reported from empirical evidence. However, these frameworks have their distinct weaknesses when applied in the selection process for optimal adaptive reuse alternative. This paper therefore focuses on developing and testing an integrated multiple-criteria decision assessment framework for the selection of best adaptive reuse alternative from two case study buildings, in New Zealand, toward achieving sustainable town-centre living.

    The Status Quo of Prefabricated Housing: An investigation into New Zealand Construction Sector
    (9/12/2022) Shahzad, W; Jelodar, M; Nesarnobari, S
    The increase of population in large cities of New Zealand (NZ), propelled by the massive number of immigrants after COVID, has caused a shortage in housing supply. Prefabrication has been advocated as a potential solution to this problem. Its uptake in NZ is relatively low despite its benefits. So, building capacity and more capability are essential for the prefabricated housing (PH) supply chain (SC) by identifying obstacles and proposing methods to tackle them. This research aims to assess and map the SC for prefabricated housing projects (PHP) in NZ. The investigations include key industries, trades and skills in this construction system. For this purpose, a comprehensive analytical approach is followed, integrating bibliometric search and qualitative discussion: 1) recent PH research keywords, pros&cons; to identify factors limited PH sector to deliver NZ supply requirements 2) study gaps in PH sector 3) prefabricated construction research directions in the future. Results show lower uptake of prefabrication through SC and knowledge, negative perception, skill shortage, cost and finance, lack of coordination and communication, site operations, design shortage, and lack of design alteration to respond to site. Consequently, various influential factors hindering its uptake were discussed, and identifying the industries, parties and trades involved was performed.

    Transaction Cost of Offsite Construction (OSC): A New Zealand Study
    (8/12/2022) Ramesh, S; Shahzad, W; Sutrisna, M
    Offsite construction (OSC) has been put forward as a solution to many prevailing challenges facing the construction industry, including but not limited to low productivity, housing shortage, lack of innovation, and poor-quality outputs. The uptake of OSC is relatively slow in the New Zealand construction industry. With only 10% of all the new builds using the OSC approach, it is evident that the potential of this construction approach is under-utilised. Many barriers have been identified as responsible for low uptake, including cost-related barriers. This study investigates the transaction cost of OSC, which is an extra cost to the project development cost and is generally overlooked in the project planning and development stage. This study aims to identify the factors that contribute to the transaction cost of OSC in New Zealand, alongside investigating the impact of transaction cost on overall project delivery and factors that can minimise the transaction cost. A questionnaire survey was conducted involving OSC practitioners in New Zealand. It was noted that consultation with building consent authority, the complexity of interface design, limited capacity of offsite manufacturers, and highly skilled workforce requirements contribute to transition cost during concept design, technical design and procurement, manufacturing, and on-site assembly stages. Consequently, disputes between stakeholders, uncertainty, an overall increase in project cost, and reluctance to use OSC may occur. It is noted that the use of innovation like automation, building information modeling, design for manufacturing and assembly, and consenting process to suit OSC holds the potential to reduce the transaction cost.
