Two probabilistic life-cycle maintenance models for deteriorating civil infrastructures

Dynamic traffic management plays an essential role within the Dutch national traffic and transport policy. To continue the contribution to the implementation of this policy, it is necessary that the dynamic traffic management is further developed and implemented. A pro-active and network-wide approach to traffic management is envisaged to replace the more reactive and locally oriented approach currently being taken. The Ministry of Transport, Public Works and Water Management has defined a framework, the traffic control architecture, as part of the national Architecture for Traffic Management. We present the traffic control architecture for which we focus on the role of a so called frame of reference in this architecture. The developed frames of reference is presented and the experiences of the application discussed.

Since 1998 a formal cooperation exists between Rijkswaterstaat, the Dutch operator for the main road network, and the KLPD, the National Traffic Police. In a five year agreement between the Ministry of Transport, Public Works and Water Management and the Ministry of Justice it was acknowledged that the KLPD should play an important role in fighting the continuous increasing congestion problems and that a better cooperation between Rijkswaterstaat and the KLPD was needed. It was arranged that the KLPD and two regional police forces could hire personnel and buy equipment to form rush hour teams. In the agreement also an evaluation program was mentioned. In this program several studies were done to determine the effects of these measures on flows, speeds, travel times, etc. As part of a contract with the AVV Transport Research Centre, Grontmij Consulting Engineers did most of these studies. Also a road user inquiry and a cost-benefit analysis, based on the results of the several impact analyses, were conducted. The evaluation program is described and the results of the several studies, including the road user inquiry and the cost-benefit analysis, are given.

PROTEUS, a technical and management model for aquatic risk assessment of industrial spills

The effectiveness of Kenyan government ministries in delivering their mandates has long been a concern. This raises an issue with type of leadership approach that has always been adopted by these government ministries. A notable case, has been seen at the Ministry of Lands, Public Works, Housing and Urban Development. It is foreseeable that in reality, competent management and leadership have determined successful or unsuccessful operations in many other agencies and organizations at large. The purpose of this study was to ascertain whether and to what degree democratic style of leadership affect performance of Ministry of Lands, Public Works, Housing and Urban Development Government. This study looked at the effect of transformational leadership style on the performance of Ministry of Lands, Public Works, Housing and Urban Development in Kenya. This study relied on transformational leadership theory, path goal theory, team leadership theory and leader member exchange theory frameworks. This study used a descriptive research approach and targeted 188 employees at the Ministry of Lands, Public Works, Housing and Urban Development in the government of Kenya. Primary data was collected using structured questionnaires and thereafter analyzed descriptively using statistical packages for social sciences (SPSS) version 26. The findings from the study revealed that employee motivation had a significant positive effect on organizational performance of Ministry of Lands, Public Works, Housing and Urban Development in Kenya. The study found that 36.7% in variation of performance was attributable to employee motivation. However, the study found that employee work commitment had a moderate negative significant effect on organizational performance of Ministry of Lands, Public Works, Housing and Urban Development in Kenya. Lastly, the researcher found that employee creativity significantly and positively affected organizational performance of the Ministry of Lands, Public Works, Housing and Urban Development in Kenya. the study found that 62.4% in variation of performance was aa a result of employee creativity. The therefore concluded that employee motivation and employee influenced organizational performance whereas employee work commitment negatively influenced organizational performance. The researcher therefore recommended that management and policy makers need to emphasize on the need for strategy and policy formulation that fosters creativity among employees for them to achieve better performance. Future research was recommended to be done on the effect of leadership attributes on sustainable performance of government ministries in Kenya. 

The research aims at determining the impact that the ethical leadership, as an independent variable and through its dimensions (fairness, Power sharing, Role clarification, People Orientation, Integrity, Ethical guidance), has on job embeddedness as a dependent variable through its dimensions (Fit, Links, sacrifice). The research is carried out using a sample of workers which consists of (194) worker at the Iraqi ministry of construction and hosting. The significance of the research is in shedding light on the practical aspect of the reality of ethical leadership and its impact on the job Embeddedness of the Iraqi Ministry of Construction, Housing, Municipalities and Public Works in order to identify the problems and obstacles it faces and to provide the necessary proposals and recommendations in this regard. The research reached a number of results, the most important one is : There is an impact and correlation between ethical leadership and job Embeddedness in the Iraqi Ministry of Construction, Housing, Municipalities and Public Works.

This paper describes a four-month study performed for the Dutch Minister of Transport, Public Works, and Water Management that examined the consequences of alternative policies for providing flood protection to the nontidal branches of the Rijn and Maas Rivers in The Netherlands. The paper focuses on estimating the flood damage that would occur under alternative safety standards, estimating the financial costs of alternative dike improvement strategies, and estimating the damage that would be inflicted on the landscape, natural, and cultural values along the rivers under each of these strategies. The primary objective of the study was to identify policies that would provide a high level of safety, would not cost too much, and would preserve as much as possible of the existing landscape, natural, and cultural values along the rivers. Less than six months after the completion of the study, the Dutch Parliament approved a new river dike policy that was based on the study's results.

This research was aim to analyzed the increasing management supervision capacity and project control and technical competence of human resources in Ministry of Public Works and Housing in project supervision and control division. Data was collected through interviews of three parties, which are: the supervisor of the activity organizer, the main controller of the activity and the implementing organizational unit. In addition, data was also collected by examining relevant documents at the Ministry of Public Works and Housing. The results of this research indicate that the capacity of the project supervisory and control management and technical competence in managing roads in the Ministry of Public Works and Housing have not yet been fulfilled. To fulfill the project management and supervision management capacity, four main factors are needed: Improving the Quality of the Independent Supervision System in Works Unit (Satker) and The National Road Implementation Agency (BPJN),. The re-organization of The National Road Implementation Agency (BPJN), of the Directorate General of Highways., Improving the quality of Human Resources (HR) Directorate General of Highways, Ministry of Public Works and Housing., To improve the quality of construction service providers (contractors and consultans). This research contributes to the improvement of the project’s supervisory and control management capacity so as to reduce the problematic packages each years, those that are late, unfulfilled quality and pass the fiscal year.Keywords: implementation of national road infrastructure, supervision and control.

The value of reflection on the evolving individual and collective practice of public policy innovation in water management: An action science approach

Most people in the world now live in urban areas and their shared quest for better cities is embodied in several Sustainable Development Goals of the United Nations. These indicate that successful cities need jobs, adequate housing stock, effective governance, and other support systems. At the most basic level, they need a basket of core public works services like clean water and efficient transit, among others. These must be provided to improve public trust in government by addressing equity and affordability while also improving operational and cost efficiency. These targets are moving as transitions are occurring from stove-piped to integrated services, even while social contracts between government and the private sector are also shifting. Essential tools to improve cities include urban planning and infrastructure development, but applying them effectively faces challenges like climate change, inequality, social disorder, and even armed conflicts. This paper focuses on seven core public works services for drinking water, wastewater, stormwater, trash collection, mass transit, streets and traffic control, and disaster management. It reviews how these have evolved in the US, how they are organized under the federalism system, and how the goal of integrated management is being pursued. Challenges to integrated approaches include increasing responsibilities but lack of funding, political stress, and rule-driven and internally oriented management. Methods for performance assessment are explained under legacy systems based on methods like indicators and benchmarking applied to public works systems. Current methods focus on regulatory targets and the details; information has been shallow and not always timely. This paper projects how the performance assessment of core public works systems can be broadened to address goals like those of the SDGs and assesses why it is difficult to rate major systems. Examples of the activities of NGOs are given and an example of how progress toward SDG6 is included to show why performance management of integrated management applied to linked systems is needed. Performance dashboards with open government are currently the most common pathways, but emerging methods based on data analytics and visualization offer new possibilities. Reviewing the status of public works management shows that it is an important branch of the field of public administration, and it can be presented as a professional field with its own identity. The findings will support educators and researchers as well as provide policy insights into public works and stakeholder engagement.

The site whose excavation is here recorded is a small kite-shaped enclosure all but obliterated by ploughing. It is situated (ST (179) 942197; 6-inch sheet ST 91 NW) at the southern tip of a spur known as Berwick Down 1 mile north of the village of Tollard Royal on the borders of Wiltshire and Dorset. It is surrounded on its south or downhill side by a semi-circular bank and ditch. The locality has been recently described briefly by H. C. Bowen and P. Fowler whose plan (1966, 46–8, fig. 2) is here reproduced (fig. 2). The other two sites occupying the 16 acres of the spur comprise:(1) An Iron Age settlement to the north consisting of a concentration of unenclosed pits, a large round house demarcated by a pennanular palisade groove and two cross-dykes.(2) A circular enclosure 2½ acres in extent containing Romano-British hut platforms and crossed in its southern sector by a modern fence. To the north of this fence the earthworks have never been ploughed and are in a state of preservation, only too rarely found in southern England. To the south of the fence the downland has been heavily ploughed over a number of years.The earthworks of the kite-shaped enclosure had become so degraded that in 1962 the Ministry of Public Building and Works initiated a trial excavation under the direction of Mr E. Greenfield. With the assistance of Miss V. Russell, Mr Greenfield covered the area with a 10 foot grid of test-holes which were expanded into trenches when required. In 1965 the site was put down to grass and the earthworks planned in the spring by members of the Royal Commission on Historical Monuments, by which time the bank and ditch of the kite-shaped enclosure were virtually invisible. In August and September of that year the interior of the enclosure was completely stripped by the author on behalf of the Ministry of Public Building and Works.

ABSTRACTThis contribution analyses how citizen sensing initiatives can contribute to or, contrarily, hinder the governance of certain or uncertain public health risks. It draws on the example of the Schiphol Airport case, where citizens developed a bottom-up system for tracking and reporting noise after the Dutch Minister of Transport, Public Works and Water Management responded to their complaints about expanding the airport with the statement that ‘Noise cannot be measured’. Despite the State’s position of no adverse effects on the inhabitants’ well-being, local residents started reporting ailments ostensibly linked to the increase in noise pollution. The central questions this contribution addresses are: how did lay people living near Schiphol use citizen sensing to respond to the risk represented by the increase in noise? How did this bottom-up initiated monitoring intertwine with the traditional top-down governance of the risk? The interplay between four theoretical concepts related to the case (citizen sensing, risk governance, lay people and social accountability) serves as a lens of observation for analysing the case. The ultimate goal is to assess whether ‘pure’ citizen sensing, only recognized by the institutional system at a later stage, can succeed in fostering social accountability of institutional actors to citizens exposed to a specific public health risk.

THE hydrographical data relating to the Nile and its upper reaches were published last year by the Public Works Ministry of Egypt in a report entitled “Nile Control,” which was reviewed in these columns on December 30 last. The information was collected for the use of the Technical Commission which was appointed last year to report upon the various projects prepared by the Ministry for controlling and distributing trie Nile waters in Egypt and the Sudan. The report of the Commission has now been published (“Report of the Nile Projects Commission,” Cairo, 1920). The Commission consisted of two hydraulic engineers of wide experience, Mr. F. S. J. Gebbie, nominated by the Government of India, and Mr. H. F. Cory, nominated by the Government of the United States; also of Dr. G. C. Simpson, nominated by the University of Cambridge as a physicist whose scientific knowledge and experience were desired in connection with problems in water measurement. Criticism of the projects had been rife for many months, and had culminated in a series of charges being, brought against the Ministry of Public Works by Sir W. Willcocks and Col. Kennedy, in which falsification of data and suppression of records were alleged. More than half of the report is taken up by a consideration of these charges by the Commission, which has reported unanimously that there had been no falsification or any fraudulent manipulation of data.

This research was conducted at the Jambi Province Public Works and Public Housing Office (PUPR). This research is entitled "Design of a Website-Based Archiving Information System at the Jambi Province Public Works and Public Housing Office (PUPR)". The purpose of this research is to document the process of designing an information system that functions to provide information to the PUPR Office of Jambi Province. This research was conducted qualitatively by conducting interviews and observations with the PUPR Office of Jambi Province to complete the research. The document filing system of the Jambi Province PUPR Office was designed using the prototype method. As a result of the analysis and observations made, it can be concluded that one effective way to facilitate the work of employees in finding documents is to build a web-based archiving information system. This system is expected to produce information quickly, precisely, and accurately without reducing the value of the information itself.

Various programs on sustainable forest-soil-water management have been developed and occasionally conducted by the Indonesian Ministry of Forestry, Ministry of Agriculture, and Ministry of Public Works under various programs. Unfortunately, the achievement of such programs were not satisfactorily. Currently, there exist 2 inter-sectoral initiatives called the National Movement for Water Conservation Partnership (NMWCP) that focused on water conservation and Reducing Emission from Deforestation and Forest Degradation (REDD+) that focused on emission reduction of greenhouse gasses through reducing deforestation and forest and land degradation. Both programs could be closely linked to carbon trade mechanism as a potential of gaining international financial supports. In principal and function-wise, the 2 programs were not distinct, particularly with regard to managing deforestation, forest degradation, forest-land-water conservation, and community empowerment/stakeholders. In principle, water conservation is inherent with forest function. In the other side, Papua is a vast region dominated by mountainous area comprises of many watersheds. In this regards, the need of having an Integrated Watershed Management (IWM) is inevitable. Therefore, collaboration between the 2 inter-sectoral programs could be the best solution for Papua. Through collaboration scheme, it would be possible to involve wider stakeholders and have more potential of generating international financial supports to carry out a more effective and efficient management of forest, land, and water.

Prediction of incident duration is very important in Advanced Intelligent Traffic Incident Management and the accuracy of prediction can provide exact information for travellers. It is widely used in the area of ITS. In this paper, K-Nearest neighbor (KNN) is employed to predict the incident duration, which puts forward a new distance metric and weight determination method. This KNN model is created based on the incident data set collected by DVS-Center for Transport and Navigation, Ministry of Transport, Public Works and Management, the Netherlands. Moreover, a simulation based on Matlab is used for incident duration prediction and optimizing the best k value. Finally, an error analysis is made based on this simulation. As a result, this method (KNN) obtains high accuracy and has a better effect than Bayesian Decision Method-Based Tree Algorithm. So it can be effectively applied to intelligent traffic incident detection and clearance systems.
