Factors influencing the adoption of information technology in a construction business

Construction firms are increasingly utilizing information technologies to better manage geographically dispersed projects. Often these technologies involve changes to existing working practices and processes and are viewed as disruptive by members of the organization. Understanding the factors that can influence individuals’ intention to utilize technology can assist managers to implement strategies to increase and improve the uptake of technologies and improve the innovation adoption process. Using a case study organization, factors identified in the Unified Theory of Acceptance and Use of Technology (UTAUT) are examined and the UTAUT is extended and by including resistance to change and top management support. The findings indicate effort expectancy, internal facilitating conditions and top management support all influence individuals’ intention to use information technology. The results also show that resistance to change or fear of change does not always play a role in innovation adoption. The findings reinforce the need to support new technologies from both a managerial and technical perspective.

Sustainable retirement living : what matters

There is a growing demand for sustainable retirement villages in Australia due to an increasing number of ageing population and public acceptance of sustainable development. This research aims to gain a better understanding of retirees’ understanding about sustainable retirement living and their attitudes towards sustainable developments via a questionnaire survey approach. The results showed that the current and potential residents of retirement villages are generally very conscious of unsustainable resource consumption and would like their residences and community to be more environmentally friendly and energy efficient. The cost of energy supply is a concern to majority of respondents. Education is required to residents about recycling household waste and how to use available facilities. A better understanding of retirees’ awareness and attitudes towards sustainability issues helps to improve the sustainable developments of retirement villages in the future.

Sustainable innovation for Queensland’s housing design : a case study

This research provides an assessment tool that assists the selection process of sustainability in detached suburban housing. It investigates the implications of using different design and construction methods including architecturally designed houses, developer housing and prefabricated houses. The study simulates one example of the three types of houses that have been chosen to fulfil a real client brief on a real site on the Sunshine Coast, Queensland Australia. Criteria for sustainability assessment are formulated based on literature reviews, exemplar designs and similar research projects for which the houses can be adequately evaluated. This criterion covers aspects including energy use, materials and thermal performance. The data is collected using computer models and sustainability assessment software to compare and draw conclusions on the success of each house. Our study indicates that architecturally designed housing with prefabricated building techniques are a better alternative to generic developer style housing. Our research provides an insight into the implications of three key elements of sustainability including energy use, materials and thermal performance. Designers, builders, developers and home-buyers are given an insight into some options currently available on the housing market and how the choices made during early design stages can provide a more positive environmental impact.

Estimating demolition costs for single residential buildings

With the increasing stock of aging structures, building
demolition is becoming achallenging research field from
the perspective of management. As the converse of
construction, management of demolition puts forward some
new management themes or adds some new contents
even though the same issues are faced in construction
management. This research aims to develop a quantitative
approach to estimate the costs of a demolition project. A
cost analysis method is presented to systematically break
down the cost components involved in the demolition of
a structure. Due to the lack of robust research in theory
and systematic summary in practice to date, the economic
performances of demolition will be studied through acase
study, and the majority of parameters are derived from
actual experiences in practice. The proposed demolition cost
estimation method is applied to the actual form of building
elimination (Scenario 1), and further comparison is carried
out with two other elimination methods, which are the newly
developed deconstruction (Scenario 2) and mechanical
demolition (Scenario 3). Deconstruction is found to be the
most profitable in this particular instance, and is closely
followed by the actual form.

A preliminary study on human resource management in international construction

As construction companies continue to explore foreign construction markets, various international construction projects are being undertaken in all corners of the world. In an international construction project with many unique and complicated characteristics, human resource management can play a significant role in promoting the efficient use of complex human resources. The aim of this paper is to establish a valid foundation for further research on measuring the impact of human resource management economically for international construction projects. The paper examines human resource management literature and identifies the application of the related management techniques to the construction industry. In addition, the paper uses the literature analysis to describe the nature of human resource management with particular reference to international construction projects. In particular, the research described in this paper identifies economic performance factors in the implementation human resource management in international construction projects. This paper also identifies the social effects of human resource management practices.

Allocating risks in public-private partnership projects using a transaction cost economics approach - a case study

Public-private partnership (PPP) projects are often characterised by increased complexity and uncertainty due to their idiosyncrasy in the management and delivery processes such as long-term lifecycle, incomplete contracting, and the multitude of stakeholders. An appropriate risk allocation is particularly crucial to achieving project success. This paper focuses on the risk allocation in PPP projects and argues that the transaction cost economics (TCE) theory can integrate the economics part, which is currently missing, into the risk management research. A TCE-based approach is proposed as a logical framework for allocating risks between public and private sectors in PPP projects. A case study of the Southern Cross Station redevelopment project in Australia is presented to illustrate the approach. The allocation of important risks is put under scrutiny. Lessons learnt are discussed and alternative management approaches drawing on TCE theory are proposed.
