Perceptions of Skilled Labour Attributes on Delays in Construction Projects in India
Published Conference ProceedingsEvidence from the literature suggests that the causes of delays in construction are well
researched. Client, contractor, consultant, design, equipment and material related aspects have
varied influence on the occurrence of delay. However, the perception of various labour
attributes on the occurrence of delay have been least investigated. Thus, the objective of the
paper is to identify the various labour attributes that cause delay and examine how these
attributes influence the occurrence of delay. A survey was conducted among various
stakeholders that include engineers, contractors, clients, project managers, architects,
supervisors, labour contractors and skilled labourers to collect the data on the perception of
labour attributes that cause delay. To conduct the survey a questionnaire was distributed among
75 individual stakeholders selected through random sampling process from 3 construction
projects in Bhubaneswar city of India. A perception index was developed based on weighted
average method to examine the relative influence of the labour attributes on delay followed by
descriptive statistics analysis and significance tests to establish the interlinkage between labour
attributes and their consequences that cause delay. Findings revealed that lack of appropriate
skill, lack of adequate remuneration, poor commitment by the labours to the project work are
the major labour attributes which engender delay in construction projects. It is also found that
lack of skill and competency lead to poor quality of work and consequently rework and delay.
Poor remuneration prompts poor commitment to the projects. Poor commitment slows down
the speed of work, and regular availability to the project and consequently influence the level
of output, thus contributing to the delay of the projects. The findings contribute to the discourse
of delay in construction from the labour attribute point of view
Influence of Administrative and Political Authorities’ Decisions on the Construction of Community Development Projects in India
Published Conference ProceedingsConstruction of community development projects, particularly in rural areas of India is a
challenge. Administrative and political authority decisions play a major role on the construction
of these projects. Therefore, the objectives of the investigation are (1) to explore how and to
what extent the administrative and political decisions influence the executive agencies at the
local level, and (2) to examine the various project parameters that get influenced by such
decisions. The investigation was conducted by using the case study of two Community
Development Blocks in Odisha State of India and by employing a survey research method.
Findings suggest that the decisions influence the construction of projects both positively and
negatively. The decisions are found to facilitate funding of projects, administrative and
technical approval of projects and build confidence among the contractors and beneficiaries;
however concurrently some of the decisions negatively influence the local executive agencies
like Block and Village panchayat authorities, technical personnel, design of projects and
quality of work, and also engender conflict among the stakeholders, thus influencing the
execution of the projects adversely. Besides, the major implications of the negative influences
of the administrative and political decisions are setting up of unrealistic target for completion
of projects, pressure on spending of funds within unrealistic period of time, poor quality of
work, delay in project execution, delay in delivery of projects, poor design of projects,
unrealistic estimated project duration, unrealistic project estimate, and conflict in project
planning and allocation
Exploring the Politico-Cultural Dimensions for Development of Smart Cities in India
Published ArticleIndian cities seem to be in transition regardless of the various sustainability
challenges they have experienced in recent years. Globalization, market
economy, and technological developments have brought economic, social and
infrastructural advantages. However, population growth, proliferation of urban
functions, insurmountable increase in size of cities, and environmental crises
because of climate change have caused the cities to experience severe spatial,
infrastructural and environmental ailments. Besides, the significant rise of
Information Communication Technology (ICT) industries in the cities and
their socio-economic and spatial influence have brought about inequitable
development. At this juncture emancipation of a political will to build smart
cities in India provides a new impetus for changing the planning perspectives
and warrants a politico-cultural discourse to examine the prerequisites and
paradigms, which could aid in development of smart cities in India. Drawing
upon the stimulating mix of past experiences and prospective approaches
across the world and discussions with experts in the political science, local
governance and urban development, this explorative paper provides a
discourse on the concept of smart cities, opportunities, challenges and the way
forward to realize the goals of smart city development in a heterogeneous but
democratically unified country like India. Based on the discourse, it is argued
that the current urban governance system is not congruent for development of
smart cities in India. Therefore, it is advocated that a cultural theory inspired
politico-cultural mechanism be explored and crafted to assemble the requisite
elements of an urban governance system that should enable the dynamics and
cohesion needed for developing smart cities in India
MODELLING TO RESOLVE DESIGN LINKED DELAY IN CONSTRUCTION PROJECTS
Published Conference ProceedingsConsultants are the major role players in design of construction projects. It is well
acknowledged that the consultant and design linked issues are more or less integrated
and influence delay in a project. Therefore, the objectives of the investigation are to
identify the influential consultant and design related variables, which cause delay; to
evolve the causal feedback relations among the most influential consultant and design
linked variables and delay; and to develop a model to estimate the reduction of delay
under varied strategic interventions. For this purpose a survey was conducted among
120 stakeholders and professionals from various construction projects in India. By
using System Dynamics (SD) modelling principles, causal feedback relations among
the most influential parameters that influence delay were established and dynamic
hypotheses were evolved for developing policy interventions to reduce delay. A SD
model was developed by using data from medium sized building projects in India to
examine the behaviour of the project schedule and delay under different simulated
scenarios, and estimate the reduction of delay under different policy interventions
based on the dynamic hypotheses framed. Findings suggest that there exist definite
causal feedback relations among the consultant and design linked variables, such as late
reviewing and approving of design documents by consultant, delay in approving major
changes in the scope of work by consultant, delay in performing inspection and testing
by consultant, poor communication/coordination between consultant and other parties,
inflexibility (rigidity) of the consultant, delays in producing design documents,
complexity of project design, mistakes and discrepancies in design documents, and
unclear and inadequate details in drawings, which essentially cause delay. However,
the model results revealed that policy interventions based on (1) causal feedback
mechanisms involving appointment of highly competent consultant and design team,
delay in producing the design documents and delay in construction; and (2) provision
of effective communication mechanism, conflict resolution and delay in construction
can reduce delay significantly
Perspectives of smart cities in South Africa through applied systems analysis approach: a case of Bloemfontein
There is a changed perspective regarding the development of cities and increasingly many countries in the West and some developing countries, as in South Africa, are making concerted attempts to transform their cities to smart cities. Using the context of the city of Bloemfontein, South Africa and drawing on the perceptions of stakeholders, the objective of the paper is to offer a perspective on such a transformation. The study first assessed the performance of various factors and attributes that influence three important aspects of a smart city: economy, mobility and governance system. It then recorded the viewpoints of stakeholders about how these aspects can contribute to the development of a smart city. Further, Applied Systems Analysis (ASA) linked System Dynamics (SD) conceptual models based on the interlinkage and causal feedback relationships among various factors under each aspect were developed, which could assist in offering perspectives that would enable eliciting of policy interventions to develop smart cities. Findings indicate that there are potentials and positive indicators in all three aspects. It is emerged that reinforcement of the inter-relationship among entrepreneurship, innovation, productivity, economic image and international embeddedness will foster a smart economy. Efficient public transportation and advancement of Information Communication Technology (ICT) system will strengthen local accessibility and ensure an innovative, sustainable and safe transportation system that will result in smart mobility. Effective participation of stakeholders in the decision-making process alongside the elected city council and transparency will aid smart governance. The combined effect of these attributes should enable the transformation of the city to a smart city
Images of Central Areas: A Comparative Analysis between South Africa and European Cities
Published Conference ProceedingsCentral areas depict distinct images of cities. Increasingly, it is seen that the significance of the designated
central areas in many cities across the world has been relegated because of the up market developments in
other areas of the cities, particularly in developing countries like South Africa. However, central areas
could still become the nerve centres of the cities and contribute to their vitality and to the verve of residents.
Thus, there is a need to explore to know what ails the central areas, what attributes are necessary and how
to revitalize central areas of cities. Using comparative analyses of the images of central areas of different
European and South African cities, and qualitative discussions with visitors, this study explores how the
central areas of South African cities can be revitalized as well as how to make them more vibrant and
attractive. The study was conducted by using images of central areas of cities like Pretoria, Bloemfontein,
and Port Elizabeth in South Africa; and Vienna, Budapest and Cologne in Europe. It is revealed that despite
the availability of similar features, the central areas of the South African cities are less vibrant, active and
attractive than the European cities. The major reasons are lack of adequate accessibility, lack of safety and
fear of crime, and lack of animated areas to enforce multicultural activities. Besides, they do not portray
distinct attractive images in the minds of the people. The experience from European cities suggests that
land marks, such as heritage and architecture have certain contribution, but accessibility to the central areas
by different public transportation modes, prevention of vehicular movement in core areas, full
pedestrianization and walkability, cleanliness, safety, sense of belongingness, and availability of animated
areas for various activities, such as shopping, dining, meeting, entertainment and relaxing are major
contributors to the vitality of the central areas. Thus, enhancement of accessibility by major modes of
transportation, fully pedestrianization of the core areas, safety and creation of vibrant areas of multicultural
activities in addition to creation of unique images are the prime requirements to make the central areas of
the South African cities dynamic and livelier
EVALUATION OF TRAFFIC CONGESTION AND RE-ENGINEERING SOLUTIONS FOR CENTRAL AREAS OF SOUTH AFRICAN CITIES: A CASE STUDY OF KIMBERLEY CITY
Published Conference ProceedingsTraffic congestion in and around the central business districts (CBD) of South African cities is a major challenge.
Apparently, it is engendering undesirable consequences that include impeding vehicular flow, causing vehicular and pedestrian
conflicts, escalating travel time, and frequenting vehicular crashes. So, using a case study of Kimberley city in South Africa, this
study assessed the causes and degree of traffic congestion on the roads in and around the CBD area; and examined the impact of
plausible re-engineering measures to alleviate the challenge. Survey research methods were used to collect data. Land use and urban
functions influencing urban movements, road, and traffic scenario data were collected through physical and traffic survey at different
selected road sections and junctions of the CBD area by following appropriate survey protocols. Besides, road user perception and
travel behaviour survey were conducted among 208 (N= 208) road users by using random sampling process at important nodes of the
city. Relevant empirical models were used to assess the causes and level of traffic congestion, and to examine the impact of reengineering
solutions on the current and forecasted traffic scenarios. Findings suggest an appreciable level of traffic congestion is
experienced currently in some of the roads of the CBD area and the situation will be aggravated in future, specifically during the
peak hours, whereas a number of roads are highly underutilised. Re-engineering solutions such as appropriate traffic assignment and
modal split, i.e., traffic diversion ranging between 9.0% and 40.5% from different congested roads and restriction of plying of heavy
vehicles on the congested roads during peak hours and assigning them to connected underutilised roads could ease traffic congestion,
increase speed and reduce travel time and consequently enable optimal use of the majority of the roads in and around the CBD area
of the city
Design Delays in Building Projects in India: Effects and Remedies
Empirical evidence shows that design-related challenges influence delay in building projects in India. Based on case studies of building projects from the capital region of Odisha Province of India, the factors relating to consultants and design have been identified and policy interventions were compiled to reduce design linked delay. A survey method to collect data, statistical analysis and a Systems Dynamics modelling approach were used according to different scenarios to propose strategic interventions. The findings suggested that complexity of design and compilation of documents, and the combined complexity of both can cause substantial delay. The model results revealed that the combined effect of appointing competent consultants and communicating effectively could reduce delay significantly. The novelty of the study lies in using a systems approach to develop causal feedback relationships among variables, as opposed to considering one origin of the problem at a time. The study makes three contributions: (1) design-linked challenges and mechanisms of delay, based on causal feedback relationships in building construction, can be diagnosed to evolve appropriate remedial measures; (2) impacts of different interventions can be visualised quantitatively under different scenarios; and (3) an alternative methodology to examine the trend of the project period is offered
