Preventative Approach

The construction of multi dwellings is currently a focus of the New Zealand government to address housing shortages. The intention is to build en masse whilst also keeping the buildings affordable. Affordability is not expected to compromise on quality and performance of new builds. New Zealand has a strict regime for building compliance, which helps to maintain standard of building performance. However, despite this, some buildings fail inspection during construction. There is limited understanding on the reasons for such failures. Therefore, this paper aims to provide a clear and concise understanding of why and how residential building inspections fail. The study investigates the reasons behind failed inspections by analyzing 146,000 inspection reports. The report used for the study cover January 2013 till June 2016. The data set was obtained from a major urban council in New Zealand. The results identified two key reasons for failed inspections. One is technical in nature and the other administrative, which both Council and builders must work collaboratively to achieve common compliance objectives. The study provides the construction industry with important insights into the reasons for failure of building inspections to serve as a preventative approach to non-achievement of expected residential building qualities.

Cam Use

New Zealand research suggests that CAM use by GPs has decreased, while referral to CAM practitioners by GPs has increased, and that patients often do not tell their health practitioners when they are using CAM. The New Zealand Medical Council has developed guidelines for GPs who use CAM. However, there is no research in New Zealand that looks at how patients and GPs respond to CAM issues in the consultation. This paper uses data collected for two research projects on doctor-patient interaction. For this research, consultations between 105 patients and nine GPs were video-recorded. In this data set, all doctors but one were 'orthodox' and to some degree reserved judgement on CAM, albeit remaining cautious in how they made this evident. Patients on the other hand demonstrated a variety of strategies to get CAM on the agenda, and GPs were careful to couch any criticism in such a way as to protect the 'face' of patients.

Purpose Although the potential of Building Information Modelling (BIM) to generate process and performance improvement in the construction industry has been widely documented, very few projects operate in a wholly BIM environment. The purpose of this paper is to explore the factors that lead to hybrid practice in BIM across disciplines or project stages, and accommodations that must be reached within BIM project frameworks to allow for it. Design/methodology/approach In-depth semi-structured interviews were carried out with 38 BIM specialists from Australia and New Zealand, representing a variety of construction industry disciplines and roles. Data on current practice and experiences in BIM were analysed using a thematic approach within a qualitative framework. Findings Hybrid BIM practice is shown to be a common experience for practitioners in New Zealand and Australia. It is presented as a valid model of BIM adoption; both as a development stage in the process towards more complete BIM implementation, and also as an adoption model in its own right. Research limitations/implications The paper is based on data from New Zealand and Australia, which are currently developing BIM markets. Although surveys have demonstrated many similarities in BIM adoption processes internationally, results may be less applicable to more mature markets. Practical implications The paper suggests that instead of regarding hybrid BIM negatively as an unsuccessful implementation, companies should seek to identify and manage the causes and effects of hybridisation in order to improve project outcomes. Originality/value This paper addresses the management of transitional stages of BIM implementation, which is often overlooked in research.

PurposeThe purpose of this paper is to test the Porter hypothesis using the Structure–Conduct–Performance (SCP) framework for a panel data set of industries in New Zealand.Design/methodology/approachThe authors developed a mutually exclusive classification of the process-led and product-led innovation strategies and examined their impact on SCP in the high (low) carbon emission industries.FindingsThe findings show that the high-level concentration provides more beneficial opportunities for product and geographical diversification that require a high level of R&D intensity. The authors find that in high-carbon emission industries, the product-led innovation strategies have a significant positive impact on the industry structure and performance which provide support for the Porter hypothesis.Practical implicationsThe findings imply that competition effects firm-level investments, in particular, capital expenditure to address carbon emissions, as such investments give firms a head start over rivals, and increase their profit margin compared to other firms over time. Overall, the empirical results lend support to the Porter hypothesis and suggest that understanding of industries’ unique R&D attributes is critical to developing regulations to support industries in smaller economies.Originality/valueIt is the first study that examines the industry structure, R&D intensity and performance in a small developed economy of New Zealand.

The Cost

Construction cost index has been widely used to prepare cost estimates, budgets, and bids for construction projects. It can also be regarded as an indicator of cost level, which makes it valuable to public authorities for understanding the conditions in the construction industry. Accurate forecasting of future construction cost index is essential for construction industry at both micro- and macro-level. To improve the accuracy of the cost forecasting, time series modeling techniques are adopted in this study. The performance of the exponential smoothing models and seasonal autoregressive integrated moving average (ARIMA) models for forecasting the building cost of five categories of residential building (one-story house, two-story house, town house, apartment, and retirement village building) in New Zealand is compared. Exponential smoothing models can produce more accurate forecasts for cost series of the one-story house and two-story house in New Zealand, while seasonal ARIMA models outperform exponential smoothing models across the cost series for town house, apartment, and retirement village building. This study contributes toward the development of the current state of knowledge in the area of cost index forecasting for New Zealand and provides insights that should be valuable from the practitioner perspectives.

The inheritance and innovation of ancient architecture decoration art is an important way for the development of the construction industry. The data process of traditional ancient architecture decoration art is relatively backward, which leads to the obvious distortion of the digitalization of ancient architecture decoration art. In order to improve the digital effect of ancient architecture decoration art, based on neural network, this paper combines the image features to construct a neural network-based ancient architecture decoration art data system model, and graphically expresses the static construction mode and dynamic construction process of the architecture group. Based on this, three-dimensional model reconstruction and scene simulation experiments of architecture groups are realized. In order to verify the performance effect of the system proposed in this paper, it is verified through simulation and performance testing, and data visualization is performed through statistical methods. The result of the study shows that the digitalization effect of the ancient architecture decoration art proposed in this paper is good.
