Influence of Risk Transfer on Implementation of Kerra Road Construction Projects between 2019 and 2023 in Migori County, Kenya

The implementation of Kenya Rural Roads Authority (KeRRA) construction projects faces high levels of risk, but these risks are often not adequately addressed, which is reflected in the low quality of work, as well as cost and time overruns. The purpose of this study was to determine the influence of risk transfer on the implementation of KeRRA road construction projects in Migori County, Kenya. Implementation was measured as a function of project completion within the set time frame and staying within budget. This study was anchored on project implementation theory, which provides a foundation for examining the influence of the variables under study. A concurrent triangulation research design was used, as it incorporates both qualitative and quantitative aspects of the research study. The target population for the study consisted of 92 contractors, 459 constituency roads committee (CRC) members, and 2 consultant engineers. Using a sampling size formula, a total of 39 contractors and 193 CRC members were selected through simple random sampling. Two (2) consultant engineers for Migori County were selected using purposive sampling. Primary data was obtained through self-administered questionnaires to contractors and CRC members, while Key Informant Interviews (KII) were conducted with the consultant engineers. The validity of the research instruments was ensured through piloting and expert evaluation. Inferential statistics, specifically Multiple Linear Regression, were applied to determine the influence of risk transfer strategies on the implementation of KeRRA road construction projects, by testing the hypotheses for the study. Statistical significance was assessed at p < 0.05. Qualitative data obtained from the interviews were analyzed using content analysis. The study found that risk transfer strategies are mostly employed during the construction of roads in Migori County (M = 3.77, SD = 0.86) and accounted for 70.0% of the variation in the implementation of the projects. The study concluded that improvement in risk transfer strategies leads to an increase in the implementation of KeRRA road construction projects in Migori County. The study recommends that, to ensure risk transfer is properly undertaken, a system of risk reporting and remedial actions should be activated to ensure a smooth and effective road project implementation process. Additionally, KeRRA should ensure that all manpower and machinery used in road construction are insured and properly certified in accordance with occupational safety and health standards and policies.

Performance of the polyurethane foam injection technique for road maintenance applications

Road infrastructure plays an important role in strengthening transportation and driving the economic advancement of countries. However, the increasing traffic volume has accelerated road deterioration, particularly at critical points like bridge-road junctions. Traditional repair methods involving demolition and reconstruction lead to extended closures and high costs. This study explores the polyurethane (PU) foam injection technique as an alternative solution, which can reduce both repair time and costs. The research evaluates the application of PU foam in various road projects across Thailand, highlighting its ability to repair pavement surfaces and structures, even in severely damaged areas. Despite its advantages, the use of PU foam faces challenges due to a lack of standardized quality control. This paper proposes a set of working guidelines for PU foam injection, aimed at key stakeholders such as the Department of Highways, the Department of Rural Roads, and the Department of Local Administration. The findings underline the importance of establishing standardized methods to ensure the long-term effectiveness of PU foam in road maintenance. Future research should focus on refining these guidelines for diverse road conditions to support the sustainable development of national transportation infrastructure

Empirical Study on Delays in Highway Projects: A Comparative Analysis of Small and Large Projects

Delays in National Highway projects, regardless of their geographical location, have exerted a substantial impact on project performance and yielded unfavourable economic consequences. The majority of these projects in India are implemented by Public-Private Partnerships (PPPs), which use a wide range of contract types, including traditional ones such as item rate contracts and bills of quantity, in addition to more modern alternatives such as build operate transfer, engineering procurement and transfer, and recently developed hybrid models. This study examines and compares the reasons of critical delays in national highway projects in Himachal Pradesh with project characteristics. This mixed-methods study gathered comprehensive data from project participants using qualitative analysis and a survey questionnaire. Interviews and document analysis identified delay factors, which were then assessed through a structured questionnaire distributed to a representative sample of project participants. The findings highlight critical delay factors in National Highway projects in Himachal Pradesh and offer insights into the unique challenges faced by large PPP projects and small traditional projects. Despite the small sample size of 134 survey responses, the findings are significant but may have limited applicability to other infrastructure projects due to socio-economic and geographic variations. This suggests a research gap indicating that further analysis is needed to understand the challenges in EPC and PPPs for large hilly road projects, along with a focused study on organizational culture to assess highway project performance. This study contributes empirical data to the literature about the steep National Highway projects in Himachal Pradesh. Policymakers, project specialists, and stakeholders may ascertain the reasons of delays and formulate targeted actions to enhance project efficiency.

PENITIPAN GANTI RUGI DALAM PENGADAAN TANAH JALAN TOL SERPONG-BALARAJA (STUDI PUTUSAN NOMOR 422/PDT.BTH/2021/PN TNG)

The construction of the Serpong-Balaraja toll road faced issues with the amount of compensation not matching the determined results, leading to Custody of Compensation in the District Court. This article addresses two main problems: (1) Whether the Custody of Indemnity Procedure by the Ministry of Public Works and Public Housing (PUPR) and the Director aligns with the law, and (2) How the judge ruled in the Maryati case regarding the Custody of Indemnity by the Ministry of PUPR. This descriptive normative research uses literature studies for data collection, analyzed qualitatively, with conclusions drawn using the deductive method. It was found that the Ministry of PUPR and the Director General of Bina followed the consignment process correctly according to the laws, yet under Presidential Regulation Number 71 of 2012, if the eligible party rejects the compensation amount set by a final court decision, the consignment process fails to reach an agreement. Thus, the conclusion is that the Indemnity Deposit Procedure by the Ministry of PUPR in acquiring land for the Serpong-Balaraja toll road project did not comply with the applicable laws and regulations.

Population Characteristics and Habitat Management of the Useful Seaweed Silvetia siliquosa

We aimed to analyze the natural population characteristics and habitat growth conditions of the valuable seaweed Silvetia siliquosa. Its population characteristics and habitat conditions were assessed monthly from May 2022 to April 2023 and April to August 2022, respectively, on selected habitats. The average population density, coverage, and frequency of S. siliquosa were 579 ± 94.18 ind./m2, 27.82 ± 6.92%/m2, and 78.37 ± 5.98/m2, respectively. The average thallus length and width were 47.53 ± 4.35 and 46.33 ± 4.17 mm, respectively, while the branch width, thickness, and frequency were 2.35 ± 0.03 mm, 0.59 ± 0.12 mm, and 2.8 ± 0.2 times, with a receptacle length and width of 24.13 ± 2.07 and 2.81 ± 0.19 mm, respectively. Among the 40 previously known natural habitats of S. siliquosa, growth was confirmed only in Sepo, Sebang, and Bangpo. The causes for the declining S. siliquosa populations could be attributed to habitat changes due to construction, coastal road maintenance projects, habitat disturbances, and increased pollutants. Habitat substrate disturbances and changes were the main causes of the decrease in S. siliquosa growth. Studies on environmental factors and habitat degradation, growth related to environmental factors, mass cultivation, and the marine ecosystem restoration of S. siliquosa are needed.

Calibration and validation of a national transport computable general equilibrium model for economic impact assessment

Infrastructure investments are being undertaken to improve efficiency, economic activity, and growth. Therefore, policy makers are increasingly looking for modelling tools that can evaluate the impact of transport infrastructure on the economy, firms and households from the lens of economic activity and equity. We have developed a large scale national CGE model for India that is calibrated to economic data as well as validated to data observed from the Indian Railways. The novelty of this work lies in three main areas (1) The CGE model incorporates multi-modal transport with road and rail (2) It is the largest model developed so far with 33 regions, 29 industries, 312,530 kms of highways and 126,366 km of Railways (3) Validation of the CGE model. The CGE model was able to predict the tonnage freighted on the Western Dedicated Freight Corridor to within 3.9 % accuracy. The Dedicated Freight Corridor Network (DFC) contributes a 2.94 % increase in the revenue for the railways as well as a 0.08 % increase in GDP. This implies that DFC can directly contribute INR 160 billion to the 2019 GDP. The CGE model distributed the benefits of faster and cheaper alternatives to the entire economy. This was observed during the evaluation of the road projects that were found to improve GDP, household welfare and rail revenue for rail, as well as improved equity.

Quality Analysis of The Road Widening Project Towards Standards for The Grobogan Road Section - Jember District Limit (Link. 199)

Roads are a land transportation route that has been used since ancient times as a means for people to move places using existing transportation. In road construction efforts, it is necessary to have Standard Operating Procedures, or SOPs, that are used with the aim of improving worker performance, ensuring road quality, increasing profits, and company development. SOP is a method or work flow that has been standardized, is used as binding and directive instructions, and covers things from an activity that has steps or procedures. Currently, there are still many road work projects that are carried out without paying attention to existing SOPs, and this means that the quality of the concrete roads being made does not comply with applicable standards, which means that some parties may experience losses. There needs to be a good understanding of how SOPs comply with standards so that they can produce concrete of maximum quality. This writing was prepared using an analytical method using a literature study that refers to the Indonesian National Standards (SNI) and the PUPR Ministerial Regulation (Regulation of the Minister of Public Works and Public Housing).
