All the project participants need to communicate on a constant manner. The invention of cellular technology and the devices that utilize wireless communication have drastically improved the way construction industry professionals and practitioners are now able to communicate on and between the construction site and head office. The purpose of this study is to assess mobile communication devices in use in the Nigerian construction industry (NCI), with an exception of standard cell phones, offer the most efficient means of communication, and which support the greatest array of construction applications. In order to accomplish this, an opinion-based survey was conducted using industry professionals and practitioners who have considerable experience working with mobile communication devices in the NCI. The results of the study reveal that the mobile communication device predominantly being used in the industry to perform ...

This paper argues that the issue of household energy consumption and CO 2 emissions (HECCE) is a complex technical and social phenomenon that needs to be understood from both engineering and social science perspectives. This research used the concept of socio-technical systems as the theoretical framework. The research applied system dynamics as both the methodology and tool to model HECCE. The result is a population of outcomes for the HECCE in the form of space heating, hot water, artificial lighting, appliances, and cooking. The tool produced is an intuitive one with the capability of replicating reality as evidenced from the outcomes of validation done. Sensitivity analysis of different policy levers (occupants' behaviour, insulation level, etc) can therefore be done with the tool. It is concluded that the outcomes of this study would go a long way in helping decision makers draw more realistic policies for household energy consumption which is critical to the CO 2 emissions reduction agenda of the government.

The paper uses questionnaire survey of 58 respondents (facilities managers and other top managers who have FM portfolios) representing 58 corporate organisations registered with Nigeria's corporate affairs commission. It also involved interview sections in a case study setting with three interviewees representing three corporate establishments in Nigeria. Supported by empirical evidence, this study establishes the three main barriers to sustainable FM practice as lack of training and tools, lack of relevant laws and regulation, and lack of awareness in that order; while the level of commitment among organisations is reported to be mixed. Majority of respondents (52%) are however of the opinion that senior management personnel should be at the forefront of championing improvement of the level of commitment to sustainable FM practices within organisations. This paper recommends that government should: (1) fast track passage of pending eco-friendly bills such as petroleum industry bill (PIB) now stagnated at the national assembly (2) empower regulatory agencies to enforce and strengthen existing regulations on sustainable working practices and (3) create awareness on sustainability in general and sustainable FM practice in particular through advocacy and enlightenment programmes. This paper provides an enhanced understanding of the state of sustainable FM practice in Nigeria.

However, little attention has been paid to model the complex interrelationships that exist among the various variables involved, especially for the effect of qualitative variables such as occupants’ behaviour. In this regard, a methodology of systems-based approach has been adopted in this research to model the complexity of the socio-technical system of Household Energy Consumption and CO2 Emission. This paper will explore the intrinsic interrelationship between the dwellings, occupants and environment systems. The study identifies ‘cause and effect’ relationships among these systems as well as quantitatively simulates the behaviour of HECCE. A System Dynamics model is proposed to utilise the hard and soft data incorporated in this system with due cognisance to the inter-dependencies of variables that are involved in addition to mental judgement of the experts and industry practitioners. The paper also discusses the validation of the proposed model. The proposed model provides policy makers with a decision making tool upon which different scenarios regarding HECCE can be tested before implementation.

The paper uses the system dynamics as both the methodology and tool to model the policies/interventions regarding HECCE. The model so developed shows the complex interrelationships among the different policies/interventions variables and presents the basis
for simulating the different scenarios of household energy consumption reduction strategies. The paper concludes that the model is capable of adding to the understanding of the complex
system under which HECCE operate and improve it accordingly by studying the behavior of each policy/intervention over time. The outcomes of the research will help decision makers draw more realistic policies/interventions for household energy consumption which is critical to the CO2 emissions reductions agenda of the government."

The interrelationship between the building occupants (socio), the systems put in place (technical), and the building itself (technical) has added more pressure to this issue of sustainability. Building performance is therefore a function of many variables, each of which is important to analyse when carrying out post-occupancy evaluation. These variables are both "soft" and "hard", interconnected, chaotic in nature, and difficult to understand, predict and keep under control. This research then carries out an extensive literature review of modelling techniques to capture, analyse and simulate the interrelationships among these socio-technical variables with a view to finding a suitable modelling tool to conceptualise the problem. The study identified actor network theory, agent-based modelling technique, bayesian belief network, configuration modelling, fuzzy logic, morphological analysis, social network analysis, and system dynamic as modelling techniques to capture the problem. The strength and limitations of each of the techniques are discussed. The paper concludes that system dynamics modelling tool seems to be more placed in capturing the behaviour of the variables in play.

This research sought to assess a number of critical success sub-factors (SSFs), identified in an earlier study, on some selected PPP projects from the perspectives of both the public and private sectors. The study also sought to test whether there is agreement between the two sectors in their rankings and perceptions of the SSFs. A questionnaire survey was conducted to elicit the perceptions of the respondents on success factors for PPP projects. A set of 120 questionnaires was administered on respondents who were directly responsible for managing and administering construction related PPP projects. Fifty-nine (59) questionnaires were retrieved. The questionnaire used some identified success sub-factors (SSFs) to elicit the rankings of respondents on the SSFs. The retrieved questionnaires were analysed using both descriptive and inferential statistical tools. The obtained rankings were investigated to test their agreement. The findings of the study suggest that there are significant differences in the perceptions of both the public and private sectors on the rankings of the SSFs on PPP projects in Nigeria. One major implication of the findings of the research is the perception gap between the private sector and public sector on the critical success subfactors. This perception gap has the potential of affecting the acceptability and performance of PPP projects in the country. It is thus recommended that relevant stakeholders take measures to close this perception gap while formulating and/or implementing policies for PPP projects in Nigeria.

The study, therefore, aims to develop a set of key performance indica tors for measuring Design a nd Build projects in Nigeria. The specific objectives are to determine the key performance indicators for Design-Build pr ojects, examine the importance of these indicators on performance outcomes of Design-Build projects and ascertain the degree of agreement among the key stakeholders on the indicators. In the study, a set of key per formance indicators were identified from a literature search and subjected to the views and opinions of respondents using a structured questionnaire. Ninety-seven copies of the questionnaire representing 64% were received and analyzed using descriptive and inferential statistical tools. Findings reveal that eight Key Performance Indi cators were identified.

This paper identified risks inherent in residential building construction projects and then evaluated the frequency of occurrence and the severity of impact of these risks. The degree of agreements between the owners and the contractors regarding the severity of impact of the identified risks was also evaluated. A questionnaire survey was then conducted. The results indicated that 'changes in work', 'deficiencies in specifications and drawings', and 'defective design' are the three most frequently occurring risks in the residential building projects in Nigeria. Also, both the owners and the contractors perceived 'changes in work' as the most severe risk. The study findings further ascertained that there is a good agreement in the perceptions of both the owners and the contractors on the severity of impact of the identified risks. It is recommended that stakeholders in residential building projects are to take into consideration those risk factors with high severity index.

This paper sought to identify a number of factors judged critical to the success or failure of PPP projects in order to determine the criticality of those factors. A questionnaire survey was conducted based on the experience of the respondents on PPP related projects. Five main success factors (SFs) and some success sub factors (SSFs) were identified. Of the main SFs, economic viability was ranked most critical to the success of PPP projects followed by appropriate risk allocation via reliable contractual arrangements, sound financial package, favourable investment environment, and reliable concessionaire with strong technical strength respectively. The study findings further suggest that there is agreement in the perceptions of both the public and private sectors on the criticality of SFs and significance of SSFs. It is recommended that relevant stakeholders can be appropriately guided in policy formulation for PPP projects in Nigeria.
