In the construction industry, the management of knowledge is becoming an increasingly important element for success. The successful management of knowledge helps general contractors to better compete which ultimately leads to more contracts and potentially greater prots. The Life Cycle Costing assessment presented here is a small step in understanding the complex decision of investing in BIM from general contractor's perspective. This assessment has identified the cost components for BIM and has allocated the cost for a typical project.

There is no ’typical’ production process for Legally Autonomous Adults (LAD). However, some very general inputs and flows can be assumed: Physical, mental, emotional, and social or cultural inputs are provided by primary caregivers throughout the process. LADs in Arizona in the 21st century are produced in small batches. Inputs tend to be provided by consistent sources according to unique values, and the production process does not actually stop cold at the factory gate, but continues on into the next phase.

Sometimes, due to externalities like substance dependence or domestic violence, the original production process either deprives the product of essential inputs or adds toxic inputs, causing damage. The damage can carry forward into the next phases, or even be so severe that the production process is terminated. When there is a risk of such damage, then the product – the child – is removed from his original production system, taken into the custody of a state-run institution (Child Protective Services), and placed in foster care.

LADs who have experienced a foster care intervention as part of their production process are less likely to have that obligatory property of Legal Autonomy, and more likely to have obligatory properties that are detrimental to society at large. Omitting other variables, they have higher rates of incarceration, homelessness, and substance abuse than LADs who have not been in out-of-home foster care. The financial and societal costs of those dependencies are imposed on the same stakeholders whose efforts and contributions make the foster care system possible.

CPS removal triggers a system expansion that expends energy and resources in an attempt to compensate for the missing inputs and to mitigate the toxic inputs, if any, that the child’s family was adding. In a material production system, it seems illogical to construct a complex system expansion which predictably results in products lacking their most important obligatory property. That contradiction was the impetus for this paper.

The goal of this life cycle analysis is to visualize that system expansion. Then, the project seeks to quantify and compare the difference between this system expansion and the generalized original process, in units of dollars per LAD. Finally, the project assesses the statistical impacts of the system expansion on LADs, and describes further impacts of these LADs on society at large.

An inter-temporal life cycle cost and greenhouse gas emissions assessment of the Los Angeles roadway network is developed to identify how construction decisions lead to embedded impacts and create an emergent behavior (vehicle miles traveled by users) in the long run.

A video of the growth of the network and additional information are available here.

As average temperatures and occurrences of extreme heat events increase in the Southwest, the water infrastructure that was designed to operate under historical temperature ranges may become increasingly vulnerable to component and operational failures. For each major component along the life cycle of water in an urban water infrastructural system, potential failure events and their semi-quantitative probabilities of occurrence were estimated from interview responses of water industry professionals. These failure events were used to populate event trees to determine the potential pathways to cascading failures in the system. The probabilities of the cascading failure scenarios under future conditions were then calculated and compared to the probabilities of scenarios under current conditions to assess the increased vulnerability of the system. We find that extreme heat events can increase the vulnerability of water systems significantly and that there are ways for water infrastructure managers to proactively mitigate these vulnerabilities before problems occur.

The Food-Energy-Water (FEW) nexus is the interaction and the interdependence of the food, energy and water systems. These interdependencies exist in all parts of the world yet little knowledge exists of the complexity within these interdependent systems. Using Arizona as a case study, systems-oriented frameworks are examined for their value in revealing the complexity of FEW nexus. Industrial Symbiosis, Life Cycle Assessment (LCA) and Urban Metabolism are examined. The Industrial Symbiosis presents the system as purely a technical one and looks only at technology and hard infrastructure.

The LCA framework takes a reductionist approach and tries to make the system manageable by setting boundary conditions. This allows the frameworks to analyze the soft infrastructure as well as the hard infrastructure. The LCA framework also helps determine potential impact. Urban Metabolism analyzes the interactions between the different infrastructures within the confines of the region and retains the complexity of the system. It is concluded that a combination of the frameworks may provide the most insight in revealing the complexity of nexus and guiding decision makers towards improving sustainability and resilience.

In the economic crisis Detroit has been enduring for many decades, a unique crisis has emerged with the provision of water that is normally not seen in the developed world. The oversized, deteriorating, and underfunded water provision system has been steadily accruing debt for the water utility since population began to decrease in the 1950s. As a result, the utility has instated rate increases and aggressive water shut off policies for non-paying residents. Residents have consequentially claimed that their human right to water has been breeched.

In this report, I analyze possible solutions to the water crisis from both the water utility and resident perspectives. Since all utility management solutions have very serious limitations on either side of the argument, I have chosen a set of technologies to consider as a part of an impact mitigation plan that can provide alternative sources of water for the people who no longer can rely on municipal water. I additionally propose an adaptive management plan to evaluate the effects of using these technologies in the long-term. The monitoring of the effects of technological mitigations might also help determine if sustainability (efficiency and equity) could be an attainable long-term solution to Detroit’s water crisis.
