This paper introduces the concept of a Pipe Data Log (Pipe Log). The idea is not new but a Pipe Log is rarely created for new pipeline projects. A Pipe Log is frequently created as part of the post-construction process and is intended for Integrity purposes. However, creating and populating the Pipe Log as construction proceeds can provide multiple benefits: • Progress of all aspects of construction can be tracked. • Anomalies in data received can be identified immediately and rectified before the project proceeds. • Missing information can be captured before the project is completed and crews are demobilized. • The field engineer can compare with design to verify that the project is being constructed as it was designed. • When construction is complete the Pipe Log will be as well. WorleyParsons Canada Services Ltd., acting as Colt Engineering, worked on behalf of Enbridge Pipelines Inc. and created a detailed Pipe Data Log for the Canadian portion of the Southern Lights LSr Project. The Pipe Log was created using Microsoft® Excel with a line item for each individual piece of pipe that was welded in the pipeline. Information corresponding to the location of each pipe segment, welds performed, material, terrain, coating, protection, and testing was recorded. The Pipe Data Log is excellent for auditing data as the information is being entered. Information collected by the surveyor can be matched to that provided by the pipe mill and by weld and NDE inspectors. Missing or questionable information can be corrected during construction much easier than post-construction. At post-construction, the Pipe Log allows the Integrity team to quickly determine if there are other areas of concern that have similar properties to another problem area.

Child sexual abuse is one of the prevalent social ills that affect children in Zimbabwe. In response to the problem of child sexual abuse and the need to mitigate its adverse effects, Zimbabwe established the Victim Friendly System. The Victim Friendly System is a multisectoral forum made up of social workers, medical doctors, nurses, the police force and role players within the justice system such as magistrates, prosecutors, counsellors, educationists and psychologists. These professionals offer distinctive but complementary interventions to child survivors of child sexual abuse. This paper discusses the merits and lessons gleaned from using the Victim Friendly System as a multisectoral forum to tackle child sexual abuse. In researching this phenomenon, the study adopted a qualitative approach and data were collected from 38 participants and 4 key informants selected using theoretical and purposive sampling respectively. A total of 300 court files of child sexual abuse cases were also reviewed. The findings that emerged from the study show that a multisectoral approach to dealing with child sexual abuse provides the benefit of integrated service delivery. Improved outcomes for victims of sexual abuse as well as streamlined, effective and efficient operations for organisations that form part of the Victim Friendly System were also evident. This notwithstanding, the paper also discusses some areas of concern that could potentially affect how the Victim Friendly System multisectoral arrangement works. The lessons that emerged from the study provide some insights that are useful in informing guidelines for multisectoral arrangements.

This work performed a comparative analysis between the construction process carried out when building the dome at the Temple of Santa Lucía, in Ambalema-Colombia and the typical process of an octagonal dome. Additionally, the structural stability is assessed of the dome of the case study against service and dynamic loads. To compare with the case study, known domes were taken as examples from structures in Italy and Spain. The analysis includes a study on the dome’s geometry and the constructive errors found. Methodology: The dome’s stability was evaluated through structural analysis software for which the dome was simplified into a system of four articulated arches. Conclusions: As a result, it was found that the dome of the temple of Santa Lucía does not have a system to counteract lateral thrusts (a drum or its similar), which permitted the appearance and widening of meridional cracks. These cracks propagate from the base to the crown, but do not compromise the structure’s stability for service loads. The analysis for seismic loads indicates that the dome is at risk of collapse upon seismic events, even of moderate magnitudes. Originality: The study is aimed at architects and engineers interested in the theme of restoration of historical structures.

Abstract Simplified sewerage provides an improved alternative to single user on-site options in peri-urban areas in India, and contributes to the aim of reducing the need for human handling of waste (manual scavenging), and the Government's goal of making India open defecation free by 2019. This research develops a mixed methodologies approach to design, optimise and assess failure risk for a proposed installation in a village in India. A steady state simplified sewerage model was used to do the initial design which was further modelled in DRAINET, a numerical model traditionally used for building drainage systems. The input data for DRAINET were obtained from a detailed survey carried out on site, which included usage pattern and focus group data. A total of 106 properties were included in the design and the survey. Test runs were carried out for the whole site over a 12-hour period. All main pipe runs were 100 mm diameter and set to a gradient of 1:100. A risk model was developed and applied to the DRAINET results which confirmed that the design operated effectively; however, there were areas of concern at the extremities of the site, which required additional flow boosting devices or gradient changed.

The central question to be examined revolves around the attitudes and awareness of HIV/AIDS among mineworkers at a mine. Semi-standardised questionnaires were used to conduct in-depth interviews on a one-on-one basis. The findings revealed that workers had a great lack of knowledge about AIDS. While some workers had a detailed knowledge of the disease and its prevention, others were either completely ignorant about it or were in denial of its existence. The study serves as a tool and a framework of reference to the mine management on the areas of concern, to put great emphasis on IEC, in order to combat the spread of the disease in the mine. Recommendations are proposed for future research, policy making and practice in the area of HIV/AIDS.These will be in line with the factors influencing mineworkers’ perceptions of the epidemic.

This article describes the core of a larger study that examined rural special education service delivery problems as perceived by various personnel within County Boards of Education as opposed to, County Boards of Mental Retardation and Developmental Disabilities within a 12-county area of northwest Ohio. By utilizing instrumentation similar to an earlier national study conducted by Helge (1983), responses were compared between agencies within the 12 counties themselves, as well as, parallel comparisons drawn with national outcomes. Limited access to educational support services, geographic isolation, commuting distance, carreer opportunities, burnout, and scarcity of personnel were identified as problem areas. Recommendations that are low-to-no-cost are provided that address each identified problem area within the 12-county region.

This paper explores the use of functional benefits transfer to forecast the effects of waste sites on property values. The results of a meta-analysis of hedonic studies of waste sites are coupled with spatial analysis techniques to produce estimates of the effects of toxic contamination in Areas of Concern (AOCs) in the U.S. Great Lakes. Based on U.S. Census data for median home values, the methods used here suggest that approximately S5.2 billion (2005 dollars) have been lost in residential property values surrounding twenty-three of the AOCs. This compares to estimates that place the cost of remediation of all U.S. AOCs at up to $4.5 billion (2005 dollars). The case study also identifies issues surrounding the use of a meta-analysis with hedonic property value studies to support functional transfer.

Constructing a new building or any other civil engineering project from scratch is a challenge for the construction industry as novelty designs may be produced by designers but they are often constructed by low skilled labor on site. The unique and sometimes complex nature of the construction sector arises because a large number of different professional groups have different interests and requirements, which often conflict with one another. In principle, each construction company aims to construct a project without any defects from the very first activity on site right up to final completion. This aim is almost impossible to achieve throughout the entire construction duration because of many factors, including: low skilled labor, difficult site conditions, and incomplete designs, varying quality cultures in each company, poor communication and poor management. Therefore, construction defects are things which we can assume to have occurred on the site. Defects occurring during the construction process are sometimes costly and preventable mistakes. Research has shown that correcting defective components that are identified late in the construction process or during the maintenance period accounts for approximately 15% of the total construction costs. This paper presents a case study of the defects that occurred during a motorway construction project as a consequence of poor workmanship by an untrained workforce and it aims to raise awareness of the need for on-the-job training for quality managers in order to minimize defective works and reduce the project costs spent on correcting them. It also identifies the various factors that cause construction defects and suggests measures that can be taken to reduce them.
