Discriminatory Effect

Current frugal design practice is focused on the cost reduction of the product. Despite advancements in the domain of frugal Innovation, it is not systematized to develop products for all sets of users, including marginalized society. Many design researchers and engineers now dedicate time and knowledge to producing practical solutions to enhance the quality of life of the marginal community. The approach currently being adopted restricts the development of products intended for all segments of the users. In this paper, cumulative frequency distribution analysis and the Relative Importance Index is used to identify the essential attributes, which contribute to delivering actual frugal products in terms of functionality, usability, performance, affordability, accessibility, aesthetics, and robustness. The framework is beneficial to eradicate the discriminatory effect of being labeled as “Jugaad” users.

For sustained profitability, architects must position themselves to attract new clients. This involves understanding potential clients’ choices and how these might impact on subsequent satisfaction. The study ranked criteria for architect selection and how these predict satisfaction among first-time private sector clients in Lagos, Nigeria. Data from a questionnaire survey were analysed using descriptive statistics, relative importance index and categorical regression, identifying timely delivery, cost of service and quality of previous services as the most important criteria. Although personal relationship has been said to influence selection of a professional service provider, this criterion was found to be of relatively low importance here. To attract private sector clients, architects should prioritise improved service delivery and construction skill development.

The poor level of women’s participation in the construction industry has been a concern for many years. In fact, women represent less than 3% of the total workers in the Indonesian construction industry. On the other hand, the industry is experiencing a worker shortage causing it to innovatively attract construction workers by increasing women’s participation in the industry. Thus, this paper aims to understand the motivating factors for women to work in the construction industry. It adopts multi-sequence research techniques including integrative literature review, expert interviews and questionnaire surveys to collect data for the study. The data was then analysed using relative importance index and factor analysis. The findings were discussed and synthesised to develop a motivational framework for women to work in the construction industry. While this framework was developed based on the Indonesian context, it can serve as a theoretical foundation for further research regarding women’s participation in the construction industry.

This paper examines the concept of innovation management in the construction industry by studying the major components of the innovation process such as the major drivers of innovation, barriers and obstacles that prevent innovation, the enablers that motivate innovation, the practices of innovation, and the benefits of innovation both at project and company level. This paper is based on the data collected by means of structured questionnaires and analyzed throughsurvey analysis. The survey, which consisted of 46 factors involved in the innovation process, was distributed to 121 different participants, and the collected data were analyzed by the relative importance index (RII), as well as the analytical hierarchy process (AHP). The RII rankings feed the AHP analysis as the first step to rank the factors. Later, the factors are ranked according to the AHP analysis. Based on these rankings, recommendations are made to contractors, consultants, project management professionals, owners and suppliers.

Resource Planning and Leveling are two critical areas of resource management which need to be implemented by contractors to aid in construction project execution. However, in the process of undertaking these processes in their projects, contractors meet a number of challenges which discourage them from implementing Resource Planning and Leveling. Nonetheless, Resource Planning and Leveling has a number of benefits which may not be known by some contractors. The purpose of this research therefore was to establish and evaluate the challenges and benefits associated with Resource Planning and Leveling. A survey design was adopted by the researcher. A sample of 106 respondents was selected randomly and a response rate of 76% was achieved. Quantitative data was analysed using descriptive statistics and relative importance index analysis while qualitative data was analysed thematically. Contractors were found to experience serious challenges in their quest to execute Resource Planning and Leveling in their projects. The three most pressing challenges experienced by contractors were found to be: project delays (RII=0.8597); technical incompetence (RII=0.8564); materials shortages or late delivery (RII=0.8390). A number of benefits were found to entice contractors to carry out Resource Planning and Leveling in their projects. The three most significant benefits were: establishing plans for material delivery (RII=0.9215); balanced resources, reducing over allocations or overtime (RII=0.9165) and determining or predicts resources needed (RII=0.9139).

Causes Of Delays

Delays are one of the major problems construction industry faces. Delays can lead to many negative effects such as arbitration between owners and contractors, increased cost, loss of productivity and revenue, and contract termination. Various studies have been carried out to highlight the general causes of delays and suggest possible remedial measures to minimize the effect of delays on a project. This study aims to highlight the critical factors with specific reference to non-excusable delays (NEDs) only. It also suggests possible remedial measures to minimize the effects of contractor-oriented NEDs which is a significant type of delays in the construction industry. A qualitative study has been conducted for this research. Data have been collected by the use of a set of questionnaires on numerous construction project stakeholders. Relative importance index (RII) has been used for prioritizing the factors. Results show that slow material mobilization, subcontractor unreliability and shortage of labor and materials are the most critical NED causes. This paper aims to provide a prerequisite knowledge to practitioners to make a more informed decision in managing NED.
