Statistical Analysis of Delay-Causing Factors in Indian Highway Construction Projects under Hybrid Annuity Model

National highways are major transportation projects that greatly contribute to the economic and overall development of India. For speedy construction of national highways, in 2016, the Indian government rejuvenated the public–private partnership (PPP) model and approved the hybrid annuity model (HAM). In the HAM, government and contractor share 40% and 60% of total project cost, respectively, which reduces the financial burden on both. But in the present scenario, more than 200 HAM highway projects are facing delay for various reasons. To investigate the causes of delay in HAM highway projects, this paper provides a questionnaire-based, detailed statistical study of 35 identified delay-causing factors. The severity of each delay factor is elicited from 384 HAM highway construction experts including 123 government/client, 159 concessionaire/contractor and 102 consultant employees. Besides, 14 delay factors are identified using principal component analysis (PCA). Based on PCA and various other statistical analysis methods, such as ranking of delay-causing factors, correlation analysis, and hypothesis testing, results of the study indicate that delay because of land acquisition; delay in issuing various approvals/clearances; change in government laws and regulations; and inefficient planning, scheduling and controlling of projects are four major delay-causing factors of HAM highway construction projects. Moreover, this paper also provides some important suggestions to prevent delay in HAM highway construction projects.

Organisational Elements Controlling the Labour Efficiency in Sri Lankan Road Construction Projects: Engineers’ Perspective

Labour efficiency is crucial for a construction firm’s long-term viability. According to recent studies, modernising organisational and administrative procedures is essential to improving labour efficiency in many developing countries, including Sri Lanka. The perspectives of construction engineers play a key role in strengthening organisational policies and management practices in the construction industry. As a result, based on the viewpoint of construction engineers, this study aims to identify the critical organisational elements that highly influence labour efficiency in Sri Lankan road construction projects. The elements/factors were qualitatively discovered after a thorough literature review. Then, a questionnaire survey was conducted among construction engineers employed by 31 Sri Lankan road construction contractors. The Relative Importance Index (RII) method was used to quantify each element’s level of influence on labour efficiency. Based on RII values, 33 organisational elements were determined as critical, where lack of communication and cooperation between the parties, delay in salary payment and lack of labour training facilities were determined as the top three ranking elements in the list. The validity and reliability of the results were confirmed by additional statistical tests. Using problem-based communication strategies, industry consultations were conducted among construction experts to determine the necessary future measures from relevant authorities based on the identified critical elements. These consultation outcomes suggest that the organisational policies of construction enterprises currently in place addressing financial procedures, communication strategies, resource management, performance management and training development practices must be improved in light of the new normal conditions facing the industry. The study findings might help to close the gap between management/organisational policies and workforce practices. Despite the fact that the study findings are limited to the Sri Lankan road construction industry, some of them could be used to address comparable issues in other developing nations.

Flagstone empire: Materiality and technical expertise in Japanese road construction in northeast China (1905–1945)

AbstractThis article investigates Japanese imperialism in northeast China through its road construction infrastructure projects within its railway auxiliary zone (1906–1932) and Manchuria at large (1932–1945). The materiality of roads unveils a history of how Japanese engineers adapted to local practices and absorbed local knowledge in building physical infrastructure and developing their technical expertise. These engineers engaged with local practices rooted in pre-existing social and natural environments to facilitate road construction. At the same time, in Manchuria their technical expertise in construction was built on the absorption and subsequent erasure of local workers’ vernacular craft. Rather than the physical realization of an imperialist, top-down vision of modernization, imperial infrastructure projects were in fact hybrid productions of technical expertise, and local vernacular knowledge and skills. By constructing roads, engineers helped to expand Japan’s political and economic influence in northeast China, assert domination over Chinese residential areas and business interests, and coerce Chinese subjects into complying with policies and rules issued by Japanese administrations. The materials of roads—gravel, granite flagstone, and concrete—illustrate a complex relationship between Japanese imperial agents and local environments.
