Tender price indices (TPI) remain an optimum process for predicting tender prices. There have been several indices’ developments in the Ghanaian Building Industry (GBI) to help in cost management practices, for instance, building cost indices, and material indices among others. Notwithstanding, there are no indices for forecasting tender price at the design stage of building projects in the Ghanaian Building Industry. The motivation of this study is to develop tender price indices that would facilitate easy prediction of the initial cost of building projects. Through a thorough literature review and secondary data collection, the index was formulated using Laspeyres with Excel spreadsheet for the actual index. The variables considered include preliminaries and measured work sections which include the substructure, concrete work, reinforcement, masonry, lining/sheathing, window/door/stairs, metalwork, surface finishes, sanitary appliances/fitting and electrical supply/power light system of the Bills of Quantities. The finding of the study shows that on average there is a change in price of about 4.42 per cent within the eight-year period from 2008 to 2016. The study has developed tender price indices for the Ghanaian Building industry for the facilitation of the easy prediction of the tender prices at the initial design stage, however, the indices have an error margin of ±3. The development of these indices will serve as the basis for further development of other indices in GBI such as locational indices and value-based indices for effective cost management practices.

As a result of the high rate of urbanization and the attendant growth in housing demand and proliferation of informal settlements in sub-Saharan African countries such as Namibia, the development of cities has become a priority concern of the governments given the obvious socio-economic and environmental challenges that impact sustainable infrastructure/services, quality of life, health and well-being of the citizenry as referenced in the United Nation Sustainable Development Goal (UN SDG) Number 11. Whereas the governments are conscious of these daunting challenges, they remain unable to decipher sustainable solutions to them. The consequence is the pe-rennial proliferation of informal settlements, housing shortages, and urban poverty, pressure on infrastructure and services, and unemployment. Although dubbed a “Garden Town” Okahandja does not have an urban structure plan of development. This study aims to investigate the feasibility of socially inclusive urban infrastructure campus development using Okahandja as a platform. Recent research has revealed such trends as the smart city concept which embodies a sustainable approach to Inclusive Urban Campus (IUC) development towards a holistic community planning in third world countries. Dololo site in the south of Okahandja stands out as an opportune urban campus platform for diverse mixed-use including residential, business-related (entrepreneurial), educational, recreational, and others. The research employed a novel multi-focused workshop methodology for data collection with community engagement and stakeholders’ interactive participation as a key strategy to enhance the bottom-up development approach. The objectives were to identify the town planning and integrated development dynamics of Okahandja, transport are identified as key to the IUC development.

Building Construction employees essentially required sufficient welfare facilities such as a place for washing, shower, change over, eat and drink, a place to store and hang clothing. Yet, these fundamental necessities are regularly dis-regarded. Decent welfare facilities can absolutely promote health and well-being and can aid to avert contracting diseases at building construction site. The aim of this study is to examine the impact of welfare facilities on building construction workers performance in the Eastern Region Ghana. The objectives were to identify welfare facilities provided by building construction firms, evaluate the satisfaction level of building construction firms’ employees with welfare facilities in Eastern Region, and determine the relationship between provision of welfare facilities and employee’s performance. The study employed convenient sample to investigate 80 building construction employees through questionnaires administration. Data generated from the survey was further analyzed using SPSS, weighted mean formula was used to determine the mean ranking, and descriptive and inferential statistics such as mean score, percentages, frequencies and chi square were used. The study reveals that the extent of welfare facilities at various construction sites was almost unavailability of sanitary and toilet facilities, unavailability of washing facilities, and unavailability of changing room, whiles drinking water and locker facilities were available but not sufficient. The study further finds that construction employees are dissatisfied with the condition of welfare facilities provided at their various work places.

Proportional, integral and derivative (PID) control strategy has been widely applied in heating systems in decades. To improve the accuracy and the ro-bustness of PID control, self-tuning radial-basis-function neural network PID (RBF-PID) is developed and used. Even though being popular, during the control process both of PID and RBF-PID control strategy are inadequate in achieving simultaneous high energy-efficiency and good control accuracy. To address this problem, in this paper we develop and report an enhanced self-tuning radial-basis-function neural network PID (e-RBF-PID) controller. To identify the superiority of e-RBF-PID, following works are conducted and reported in this paper. Firstly, four controllers, i.e., on-off, PID, RBF-PID and e-RBF-PID are designed. Secondly, in order to test the performance of the e-RBF-PID controller, an experimental water heating system is constructed for being controlled. Finally, the energy consumption for the four controllers under the three sumption can be saved. Therefore, it is concluded that the proposed e-RBF-PID is capable of enhancing energy efficiency during control process.

Waterfront space is an important part of waterfront cities, and it carries the functions of ecological protection, tourism and urban landscape. As a city built on an island, Macao has abundant waterfront space. However, due to the geographical location, cultural and historical reasons, the waterfront space of Macao has a development gap in the use of urban waterfront space. The internal reasons for the differences in the waterfront space construction in which regions of the island are more perfect are the issues to be studied in this article. It is hoped that through the study of the current situation of Macao’s local waterfront space infrastructure construction, the main points that affect advanced cases will be sorted out. From the location, industry, and infrastructure, find out its enlightenment to other waterfront spaces in Macao that are relatively backward in construction.

Motivation is a strategy adopted by organisational managers to improve organisational performance. Most researchers have found different factors that affect the motivation on a different level. The aim of the survey was to examine the motivational strategies for improving productivity among artisans in the construction companies in the Eastern Region and the Greater Accra Region of Ghana. The study adopted a descriptive cross-sectional research design utilising the quantitative approach. A purposive random sampling technique was employed to choose 90 workers to participate in the study. A structured questionnaire was utilised to gather information from respondents. Statistical Package for Social Sciences (SPSS) and Partial Least Squares-Structural Equation Modeling (PLS-SEM) were used to analyse the data collected. Results from the survey showed that artisans see motivation as very significant in their workplace. The study found that empowerment, quality of life, and monetary incentive have significant relation with motivation and effective use of such strategies could assist construction industry practitioners to enhance craftsmen performance. The study contributes to a few pieces of literature existing in construction motivational strategies. The findings point to the fact that industrial players should pay more attention to the motivational strategies to assist artisans’ function effectively in their work environment.

In Korea construction industry, the increase of tower crane’s usage continuously and the accidents of tower crane are increasing simultaneously. But research on tower crane is insufficient for reducing the tower crane accident. This study aims to derive the importance ranking of accident factors of cab-control tower crane by AHP analysis. AHP survey was conducted on experts such as construction engineer, construction manager, safety engineer, and tower crane operator, who have more than 10-year career. The results of AHP analysis reveal that top ranking factor of cab-control tower crane’s accident is erection work. Therefore, the derived factors should be managed, and the priority measures taken for reducing the tower crane accidents according to the ranking of accident factors.

Green building rating tools used for planning and assessing the impact of buildings on the environment are continually revised in line with user needs. The appropriateness of tools for the Zambian building industry depends on whether the tools adequately meet minimum green buildings standards and the country’s environmental aspirations. The utilization of green building rating tools is important if Zambia is to achieve the real benefits of green buildings, however very little is known about the levels of utilization in Zambia. A cross-sectional study of 115 professionals from the building industry in Zambia was undertaken using a sequential mixed method approach, to investigate the level of utilization, preferred criteria and, the barriers and drivers to the utilization of tools. The significance of the study was that it demonstrated the association between utilization of green building rating tools and environmental, technological, economic, and social green buildings practices by selected professionals in the Zambian building industry. There is a need to use materials and practices that are locally based and promote the local economy. The technical needs were met in tools, that were considered easy to use, interesting and comprehensive. Some of the green building rating tools were considered unsuitable due to the absence of appropriate criteria and the main economic challenge was the high cost of certification. The association was significant between utilization and those involved in a variety of projects than those who were involved in only residential buildings. Barriers to utilization were a lack of government regulations on green buildings designs and the high cost of certification. The drivers were environmental benefits, the interest of developers in green buildings, and having technical skills. The study recommends a review of the current building regulations to include green buildings practices and materials and adaptation of appropriate rating tools.
