Positive Results

An innovative approach to integrate the activities of a decommissioning and deactivation program (D&D) with a soil-groundwater clean up program has had significant positive results saving both money and time at the Department of Energy’s Savannah River Site. The accomplishments that have been achieved by the combining the two programs have been remarkable including significant cost savings, economies of scale for sampling and document generation, and alignment of common objectives. Because of the coordination of both activities area-wide “end states” can be formulated and be consistent with the customers’ cleanup goals and federal regulations. This coordinates and aligns both the environmental clean up and D&D objectives because each must be addressed simultaneously and comprehensively. In this respect, resources from both organizations can be pooled to take advantage of the strengths of each. The new approach allows more efficient use of lean financial resources and optimizes workforce activities to attain the common objectives while being more cost effective, more protective of the environment, and optimizing the use existing resources.

The Common

This article considers evidence which suggests that Australia's current approach to the funding of non-government schools does not serve the common good. Educational provision is now segmented and a majority of private schools have resources that are either moderately or highly superior to those available in public schools. The current funding system has failed to coordinate the activities of public and private providers, leading to duplication of provision, reductions in economies of scale, and increases in per-student costs. Students whose backgrounds and disabilities make them relatively costly to teach are heavily concentrated in the public sector. Private sector recurrent subsidies are tied to public sector per-student costs, forcing Australian taxpayers into an upward spiral of increasing outlays. The article concludes by outlining some proposals for change that would lead to a new approach to funding Australia's schools.

A project started last year called MORE-CONNECT, which focuses on the renovation of buildings (especially building facades) using prefabricated elements. The aim of this project is to create a competitive solution consisting of a technology and processes which enable fast, cost-effective renovation with minimal difficulties to inhabitants. Significant cost savings in renovation costs lies in the usage of prefabricated elements and the reduction of construction works on site. The precision of the prefabricated element depends on the precision of the construction, project and building documentation. This article offers an overview of the possible methods for building documentation and spatial data transfer into BIM (Building Information Modelling) software. The description of methods focuses on laser scanning and photogrammetry (including RPAS based), its advantages, disadvantages and limitations according to the documented building, level of renovation, situation on site etc. The next part involves spatial data transfer into BIM software. A proposed solution is tested in a case study.

River Site

The Savannah River Site (SRS) spring-operated relief valve (SORV) maintenance intervals were evaluated using the American Petroleum Institute’s (API) inspection updating approach in API RP 581 for Risk-Based Inspection (RBI) technology. In addition, the impact of extending the inspection schedule was evaluated using Monte Carlo simulation (MCS). The API RP 581 approach is characterized as a Weibull analysis with modified Bayesian updating. Initial Weibull parameter estimates were updated using SRS’s historical proof test records contained in the Center for Chemical Process Safety Process Equipment Reliability Database. The API RP 581 methodology was used to estimate the SORV’s probability of failing on demand and the annual expected risk. An illustration of the inspection costs versus the associated risks is provided. Current practices are reviewed, and recommendations are made for extending maintenance intervals. A cost-effective maintenance frequency balancing both financial risk and inspection cost is demonstrated.

Rapid Manufacture

The rapid manufacture of a great range of variant products is gaining importance in global competition. Customers are increasingly demanding products which are matched to their specific requirements. The production of these customized variants gives a competitive advantage, but also leads to higher production costs. Almost every step in the process of making a product is capable of generating variants. A key element in variant management is to make the variants as late as possible in order to exploit economies of scale in the earliest stages of production and to minimize the complexity of production [9], [6]. The technique of the highly flexible final production stage consists in achieving a late emergence of variants by integrating the variant-specific manufacturing processes into the assembly stage. This means abandoning the conventional distinction between manufacture and assembly in favour of a division into a preliminary, variant-neutral production stage and a final production stage where the variants take shape. The final production stage includes all the processes that yield variants. The complete manufacture of variant-neutral parts and subassemblies takes place in the preliminary production stage, as does the prefabrication of those parts and sub-assemblies which are to undergo final manufacture as variants in the final production stage. The result is a procedure capable of producing a broad spectrum of variants economically and with minimal throughput times. This paper describes the philosophy of this new approach and concludes with a practical case study.
