The implementation of the road project in Wonogiri Regency was often different between the planning with has be held that making problem for contractor like as late work and cost overrun. Therefore, the purpose of this research is knowing what is cost overrun factors and also amount of cost overruns of the road project in Wonogiri Regency which used APBD 2017 and 2018 experienced by contractor. This research was conducted by asking questions to the contractor who worked on the road project in 2017 and 2018. The analysis of this research has using the SPSS program. Based on the analysis has been done, field regulation become dominant of cost overrun. The lack of provision of field support facilities and the limited size of the project area are the reasons why field regulation factors can be a major factor causing cost overruns on road projects in Wonogiri Regency. Based on the answers from respondents it can be concluded that the contractors who experienced a swelling cost of 1% -5% there were 44 respondents, then for the cost swelling of 6% -10% there were 28 respondents, and 11% -15% there were 2 respondents, and 16% -20% only 1 respondent.

Project Delays

Purpose The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures. Design/methodology/approach The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays. Findings About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related). Research limitations/implications The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis. Practical implications The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana. Originality/value The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.

The Impact

Scope creep has been a day-to-day occurrence in almost every major road project causing a considerable cost overrun with no early dimple. This paper offers a critical appraisal on the dominant causes behind scope creep in the road projects. A comprehensive literature survey was undertaken to explore the factors specifically contributing scope creep and various control measures that are adopted, among other purposes, in at least reducing the impact due to scope creep in the final delivery of road projects. The study included interviews with 15 experts to identify major issues and add their hands-on experience. A questionnaire survey was subsequently administered among 100 industrial personnel having a cost management background in order to evaluate the effectiveness of the key performance indicators (KPIs) in terms of taming scope creep. Results from the study showed that concomitant client instructions on additional features, unclear scope and incremental changes cause scope creep throughout the project. Among 53 KPIs identified, the most effective KPI that enables adequate control of scope creep in road projects is the cost efficiency ratio. The results enable comprehending the causes of scope creep and its resultant net effect on cost control.

Injured Patients

Safety of people and traffic police on road and the provision of prompt and appropriate treatment of injured persons in road accident are urgent concerns. The nine recommendations accordingly made are 1) Considering anyone who informs about or brings to the hospitals the accident victims as innocent until proved otherwise, 2) Annual payment by all vehicle owners (as per the cost of vehicles) to generate treatment fund for any road accident injured patients in the free general (not paying or private or extended health service) outdoor or emergency clinics or ward of the public hospitals irrespective of anyone’ fault in the accident (insurance or other agencies may be assigned to handle the amount deposited and reimbursement of the payments to the hospitals), 3) Implementation of helmet wearing by motorcycle riders and pillion riders in motorcycles, 4) Stricter fine for hazardous traffic offenses, 5) Drivers of the larger vehicles should not automatically be held responsible for any accidents involving other smaller vehicles (to prevent smaller vehicles and motorcycles to drive recklessly), 6) Drivers should not be just held responsible to bear health expenses of injured patients (which is much more than the compensation required in the event of death of injured persons); this is to encourage drivers to take injured persons immediately to hospitals and prevent inclination to allow their deaths indirectly or directly; the drivers should be proportionately fined or punished as per the traffic regulations if they are found to be negligent, 7) Safe and visible platform for the traffic police to stay on the road, 8) Provision of cost-effective respirators for traffic police and traffic supervisors, and 9) Compensation for occupational hazards to the traffic police and field traffic supervisors by distributing to them adequate proportion (e.g. one-third to one-half) of the fund collected by stricter fine paid for the hazardous traffic offences. Provision of various allowances, including for hazards, and benefits is a common practice in the country. Compensation for the occupational hazards of the traffic police provides incentives to and motivates them to remain vigilant about hazardous traffic offenses day and night everywhere and, thus, is essential for the safety of the people.

An experiment was conducted in the road district of Kuopio in the winters of 1992–1993 and 1993–1994 in which the use of salt in winter maintenance on rural main roads was reduced to 1 to 2 T/road kilometer from the approximately 10 T of salt that typically had been used per road kilometer in similar conditions in recent years. On the experimental roads, salting was replaced by sanding. The cost of winter maintenance on the experimental roads increased by 20 percent on average, and the increase was higher on roads with higher traffic volumes. Slippery conditions due to ice and snow on the road surface were twice as frequent (30 to 40 percent of the time) on the experimental roads as on the control roads in the neighboring road district. There were 27 injury accidents on the experimental roads in the first winter and 25 in the second. This was about the same as the average of the five previous winters. Because the accident trend on other roads in the same time was decreasing, it was concluded that the experiment increased the number of injury accidents by approximately 20 percent on most experimental road sections. Reduced salting decreased the sodium and chloride concentrations in the needles of roadside pine trees. There were also indications of decreased sodium and chloride concentrations in groundwater. Three quarters of the population in the area was pleased with the experiment.

PurposeThe purpose of this research is to rank the most significant factors of organizational structure that can reduce time and cost overruns (nonphysical waste) in road projects of the developing countries. Additionally, the effect of factors of organizational structure on nonphysical waste in road projects is also measured.Design/methodology/approachFactors of organizational structure causing time and cost overrun are extracted through a content analysis of the published literature. Moreover, a questionnaire survey is carried out involving 128 professionals to assess the effect of organizational structure factors on time and cost overrun. Finally, to obtain a more objective evaluation, relative importance index and regression analysis techniques are utilized, and the most severe factors influencing time and cost overrun are indicated.FindingsThis study found out that top management support and procurement procedures are the most significant factors influencing time and cost overruns in road projects of the developing countries.Originality/valueA small number of studies have been conducted to investigate the effect of factors of organizational structure on time and cost overrun in the construction industry. And even more, its relation with respect to road projects of the developing countries is limited. This research highlights the effect of most significant factors of organizational structure that influence the nonphysical waste in road projects of the developing countries. Therefore, this study adds to the body of knowledge by recommending that all the stakeholders of construction project should pay close attention toward these factors to control the enigma of time and cost overrun. It might also prove helpful, if implemented to its full extent, in all the road construction activities undertaken.

The costs of construction and the future maintenance of expressways and motorways have a significant impact on the choice of technologies for their construction. The subject of the article is the analysis of the costs of construction and maintenance of rigid (concrete) and flexible (asphalt mixtures) pavements in Poland. The construction technologies and maintenance scenarios in service were analysed for selected pavement constructions of rigid and flexible motorways and expressways. The costs of construction and maintenance of these pavements in national conditions were determined. The fourth quarter of 2015 was adopted as the initial price level. On the basis of the analysis of the costs of construction and maintenance of the analysed structures, the advantage of rigid constructions made of cement concrete was demonstrated, especially in the aspect of the surface maintenance. The cost assessment was carried out for 30 years of exploitation. The concrete pavements on the road network in Poland have been used for over 20 years. They are present both on low-class roads and on the highest-class roads, i.e. motorways and expressways.

There have been growing concerns involving the penetration of Electric Vehicles (EVs) due to the time required by its battery to attain full charge. Interests in EVs had recently experienced a dramatic turn down due to mileage limitation on full battery charge amidst the cost of purchase, but most notably due to the absence of quick chargers that can keep the vehicle on the road within few minutes of arriving at the charging station. Researchers had proposed different charging schemes such as level II ac charging, dc charging, and in some cases, wireless charging schemes that later appear to be inefficient. The use of dynamic or simply road-way powered electric vehicles was also proposed in the literature. However, the proposed cycloconverter-based circuit was simulated in Simulink, and the results obtained proved that the rate of charge increased when compared to the conventional EV charging circuit. Also, the focus is on battery charging technology and battery modeling for application in an electric vehicle

We explored the attitudes of Brazilians towards different methods to deal with boar taint in pork (surgical castration without pain control, SC; surgical castration with pain control, SC+PC; immunocastration, IC; raising entire males, EM). Two surveys (Sv1, n = 441 and Sv2, n = 768) containing closed and open questions were conducted. Nearly 70% of Sv1 and Sv2 participants were unaware that meat of entire males may have boar taint and that SC is widely used in pig production in Brazil. In Sv1, acceptability of SC+PC (63%) and IC (53%) was greater than of SC (15%). In Sv2, acceptability of IC (55%) and EM (52%) was greater than of SC (18%). Open-ended responses indicated that participants objected to inflicting pain to pigs to attain a production goal, and were concerned with organoleptic traits and risks of exogenous residues in pork. Participants’ views regarding the potential increases in the cost of meat due to adoption of alternative methods varied; some argued that avoiding pain justifies an increase in the price of pork and others that this would impact especially lower income citizens. Our findings indicate that participants opposed surgical castration without pain control, and supported alternative methods. However, the concern with potential risks of presence of residues in meat, expressed by a few participants, may need to be addressed among consumers.

Loss and degradation of biodiversity is continuing despite the past conservation efforts in Nepal. Out of many potential causes, this study strives to investigate the effects of a road project on biodiversity in the Middle Hills of Nepal. Information about floristic composition was collected from the adjoining community forests using group of 30 circular sample plots, each located at 50 m and 20 m far from the edge of the road. Results provide evidence that rural road projects are contributing to reduction of biodiversity which may be due to the removal of low-yielding timber species near the road-edge. The study also suggests that proximity to road-edge reduces under- storey vegetation which will lead less capable forest to sustain its original biodiversity. However, silvicultural operations have potential to minimize the indirect loss of biodiversity caused by road projects.Banko JanakariA Journal of Forestry Information for NepalVol. 26, No. 1, Page: 70-77, 2016
