This paper gives details of the results of research on maintenance management practices and expenditures on road infrastructure in the province of New Brunswick during the period 1965-1994. An analysis of historic levels of spending on road maintenance, rehabilitation and new construction; current maintenance management practice; and the source and allocation of funds indicated three trends: (i) routine and preventive maintenance funding has steadily decreased over the past 30 years while traffic and vehicle registrations have increased; (ii) maintenance expenditures are not keeping pace with system needs; and (iii) there is a need for a review of traditional construction and maintenance management practices. Three cost prediction models were developed to determine an accurate cost for road maintenance. Based on the models and the management review, it was concluded that maintenance funding needs to be increased by 25% in conjunction with the implementation of a comprehensive maintenance management system, if the Department of Transportation is to adequately meet the current and future needs of the existing road network.Key words: road maintenance, maintenance management, road construction.

The urban road becoming more perfect, pavement engineering is from new construction to maintenance management. The authorities, from acceptance the new construction turn into survey of the road‘s situation and control of various types of damage and road conditions on time, to maintain a good condition of the road. In this study we use the CCD with the general Global Positioning System to provide GPS coordinates and have a street shooting for each 20m of road, record of the CCD road imaging system, and with GPS coordinates, the street pavement shooting can identify the highest frequency distress type within 100m of the road, and compare with the value of IRI for statistics, considering different distress conditions associated with the International Roughness Index, and to explore the causes. This study has an Urban Road Management System, it divided into road flat index query and pavement condition index query, and user can use this system know the pavement condition every section. The road maintenance unit can be judged by this indicator status of pavement roughness to develop a conservation strategy of each section, reflecting the degree of conservation of each section, making the pavement to maintain a good quality. Urban road maintenance management system is for the each authorities built the road pavement maintenance management system for pavement managers with different levels of management authority, and to assist in the system can provide information for urban roads to do planning, query and management, it is beneficial to the authorities to implementation of urban roads and other road maintenance operations, they can immediately understand the pavement condition.

Challenges exist across the three dimensions of construction sustainability (economic; social and environmental) due to low productivity, waste, safety, and environmental hazards attributed to existing construction management practices.  Lean construction (LC) has been widely accepted as a robust philosophy to enable sustainable construction (SC) practices. However, the existing literature is more inclined toward defining the integration between LC and sustainability through LC practices and techniques. Little research tackles the challenges of achieving sustainable goals within the current practices. Therefore, this paper aims to present a strategy that can help the construction industry overcome the challenges of SC in the traditional construction management practice by using LC. The challenges of SC are identified through a systematic literature review approach with metadata analysis. Compared with LC principles, tools and techniques, the strategy focused on identifying (1) the power and potential of LC principles and (2) the best LC practices/techniques that help in overcoming these SC challenges. The study results showed 20 out of 32 challenges identified can be overcome by using LC integrated with SC. Finally, a Lean Approaching Sustainability Tools (LAST) matrix is developed to provide guidelines to the construction stakeholders for the selection of LC practices/tools/techniques in overcoming the top 15 most important challenges.

Measures Of Performance

Over the past several years the Office of Pipeline Safety (OPS) in the Research and Special Programs Administration of the US Department of Transportation has begun to develop and implement a different approach to structuring its regulations and to carrying out the inspections it uses to evaluate operator conformance with the provisions of these regulations. Several new Rules have been promulgated incorporating provisions that are a combination of prescriptive, performance-based, and management-based. These rules include the hazardous liquid integrity management rules for large and small operators, the operator qualification rule, and the gas integrity management rule. The new rules have been designed to allow operators flexibility in their approach to addressing the objectives of the regulations. Such flexibility is needed because of the significant differences in the pipeline infrastructure operated by each company, and the corresponding need to acknowledge these differences to assure the objectives of regulation are achieved without imposing a needless and costly burden on the operators. Promulgation of highly prescriptive “one-size-fits-all” regulations is inconsistent with the variations present in the infrastructure operated by the US pipeline industry. One ingredient in the approach OPS has chosen is the imposition of “management-based” requirements. These requirements are so-called because they prescribe implementation of a program that includes the need for several management practices. The new rules allow some flexibility in which management practices are selected and exactly how they are implemented. Inspection against management-based provisions is different from inspection of purely prescriptive requirements. Management-based requirements provide flexibility in how operators evaluate, justify and change their practices to satisfy the intent of the rule within their unique operating environment. While such changes are designed to lead to improved performance, they will not immediately manifest themselves in recognizable changes in performance, so finely tuned measures of performance are needed to help evaluate the effectiveness of the new requirements. OPS has adopted several mechanisms to aid in the consistent inspection of the management-based provisions of the new rules. These mechanisms are discussed in the paper, as is the OPS approach to answering the question of how it will know if the new approach is working.

Interseeding red clover (RC; Trifolium pratense L.) to winter wheat (WW; Triticum aestivum L.) is a recommended management practice for wheat growers in Ontario, as it is known to provide a host of services including a significant nitrogen credit for the subsequent crop. However, fewer Ontario wheat acres are being interseeded with RC because of challenges with nonuniform stands. A survey was developed to explore why growers use the winter wheat – red clover (WWrc) system and to evaluate the management practices being used. We received 179 responses, 142 which were from growers currently practicing WWrc and the rest were from growers who had used WWrc in the past. Of those who were currently practicing WWrc, increasing degrees of tillage, wider WW row spacing, and higher RC seeding rates showed some indication of improved RC stand uniformity, and qualitative feedback from growers in the survey supports this. It is recommended that these management practices receive formal evaluation to increase the success of the WWrc system in Ontario.

Survey Approach

The link between dairy farm systems and cost of environmental compliance is not always clear. A survey of Waikato dairy farmers was conducted to establish the real (non-modelled) cost of compliance with environmental regulation in the region. Quantitative and qualitative data were gathered to improve understanding of compliance costs and implementation issues for a range of Waikato farm systems. The average oneoff capital cost of compliance determined through a survey approach was $1.02 per kg milksolids, $1490 per hectare and $403 per cow. Costs experienced by Waikato farmers have exceeded average economic farm surplus for the region in the past 5 years. As regulation increases there are efficiencies to be gained through implementing farm infrastructure and farm management practice to best match farm system intensity.

Medical Waste Management

Background:Poor medical waste management has been implicated in an increase in the number of epidemics and waste-related diseases in the past years. South Africa is resource-constrained in the management of medical waste.Objectives:A review of studies regarding medical waste management in South Africa in the past decade was undertaken to explore the practices of medical waste management and the challenges being faced by stakeholders.Method:Published articles, South African government documents, reports of hospital surveys, unpublished theses and dissertations were consulted, analysed and synthesised. The studies employed quantitative, qualitative and mixed research methods and documented comparable results from all provinces.Results:The absence of a national policy to guide the medical waste management practice in the provinces was identified as the principal problem. Poor practices were reported across the country from the point of medical waste generation to disposal, as well as non-enforcement of guidelines in the provinces where they exit. The authorized disposal sites nationally are currently unable to cope with the enormous amount of the medical waste being generated and illegal dumping of the waste in unapproved sites have been reported. The challenges range from lack of adequate facilities for temporary storage of waste to final disposal.Conclusion:These challenges must be addressed and the practices corrected to forestall the adverse effects of poorly managed medical waste on the country. There is a need to develop a medical waste policy to assist in the management of such waste.
