Cost Effective Manhole To Pipe Connection, Utkarsh Shekhar

Master of Technology Management Plan II Graduate Projects

The manhole to the pipe connection is an important part of the sewer system. Any problem in the seal connecting the manhole to the pipe results into either inflow of ground water into the sewer system or outflow into the surrounding environment. The inflow of ground water on one hand increases the volume of wastewater being sent to the wastewater plant and on the other hand, the outflow leads to the contamination of the surrounding soil. Hence, the durability and longevity of the manhole to the pipe connection is crucial.

The manhole to the pipe connection generally fails due to …

Structural Identification Of An Elevated Water Tower, James Thomas Norris

Mission Dependency Index Of Air Force Built Infrastructure: Knowledge Discovery With Machine Learning, Clark W. Smith

Theses and Dissertations

Mission Dependency Index (MDI) is a metric developed to capture the relative criticality of infrastructure assets with respect to organizational missions. The USAF adapted the MDI metric from the United States Navy’s MDI methodology. Unlike the Navy’s MDI data collection process, the USAF adaptation of the MDI metric employs generic facility category codes (CATCODEs) to assign MDI values. This practice introduces uncertainty into the MDI assignment process with respect to specific missions and specific infrastructure assets. The uncertainty associated with USAF MDI values necessitated the MDI adjudication process. The MDI adjudication process provides a mechanism for installation civil engineer personnel …

An Economic Analysis Of The Transition Of A Contingency Military Installation To An Enduring Status Using Monte Carlo Simulations, Ryan M. Amedee

Strategies For Reducing The Environmental Impacts Of Construction, Jordan Moran

The Professional Constructor

Sustainable building is a complex goal to reach even for the most seasoned project managers. If theyfocus on the ideas to reduce, reuse, and recycle that goal becomes much more obtainable. The project manager mustset his expectations and priorities from the moment the contract is signed to navigate which routes are most possible toachieve given the project scope and delivery method. The key to success is to relay the long term benefits of sustainablebuilding on to the owner, and make them realize that up-front cost should take a back seat to life cycle. This will save theenvironment and the owner’s …

Contractor Feasibility In Providing Cost Segregation Studies From Detailed Estimates: A Case Study, Ben F. Bigelow, Jeremy Robinson, John Killingsworth

The Professional Constructor

Profit margins are tight for general contractors, averaging under 3% (Construction Financial Management Association). Further, competition for projects can be very fierce, so any opportunity for increased profit or a competitive advantage in bidding bears consideration by general contractors. Cost segregation studies represent such an opportunity but the feasibility of a general contractor providing them has not been studied. A cost segregation study allows a property owner to accelerate the depreciation of certain portions of a building thus reducing tax liability and increasing cash flow. Because the information needed for a cost segregation study can be found in a detailed …
