Identification Of Key Performance Tasks To Demonstrate The Benefit Of Introducing The Facilities Manager At An Early Stage In The Building Information Modelling Process On Public Sector Projects In Ireland., Barry Mcauley
Doctoral
Modelling (BIM) governed process was investigated in this thesis. Governments are now seeking a more rewarding methodology in the management and procurement of public sector building assets. This has seen an integrated focus by International Governments on BIM as a partial solution in both managing and procuring public sector building assets. Despite BIM bringing the Facility Manager closer to project conceptualisation, there was still a reluctance and a lack of perceived benefits of having them involved earlier in the design phase. There remains a lack of clear evidence on what improved contribution the Facilities Manager can provide. This thesis provides …

A Sustainability-Based Project Selection Algorithm: Socio-Technical-Economic Project Selection (Steps) Algorithm, Bharathi Bhattu
Dissertations, Master's Theses and Master's Reports
Multi-dimensional aspects play a vital role in the task of project-decision making. Environmental effects are to be considered in addition to other technical and non-technical aspects in order to avoid undue environmental damage. This current work introduces a new decision-making algorithm (Socio-Technical-Economic Project Selection or STEPS) that is demonstrated with the use of RCA (recycled concrete aggregate) as riprap for slope stabilization and erosion control which leaches chemical arsenic when in contact with water. Arsenic has long been recognized for its lethal properties. The main intention of introducing this new algorithm is to use sustainability concepts of social, technical, and …

Thermal Envelope Analysis Of Local Authority Low Rise Housing Based On Stock Aggregation Theory Using A Remote Feature Extraction Technique., James Pittam
Theses
Understanding the buildings thermal envelope is paramount to analysing existing problems which facilitate cold bridging and low surface temperatures. As no detailed housing stock database is in existence in Ireland which describes the geometrical configuration of the existing housing stock, and to create one would be a major challenge, this research set out to develop a high speed remote cataloguing and geometrical data extraction methodology to build such a database. Replacing traditional measurement methods with a remote method allows for the rapid extraction of fagade information. A remote surveying process is proposed named, the Virtual Survey Method, for the classification …

Single-Family Housing Construction Cost In The Greater Baton Rouge Area, Justin Pierce Estes
LSU Master's Theses
Most research focused on housing costs has noted a paucity of empirical cost data for residential construction, and researchers have suggested that collecting these data for individual metropolitan areas is ideal. The goal of this study is to obtain these data and compare them to national average sources to determine how well national data represent local costs. Data collection included obtaining prices from big box stores and through a survey of local Baton Rouge residential contractors for material, square foot and assembly costs for the major components of a house (i.e. foundation, wall, roof). From the material cost data evaluated, …

Articles
The residential sector represents 27% of primary energy consumption in Ireland. This paper examines the case study of the Irish government’s national grant scheme to encourage energy efficiency retrofit in private housing. That is the Home Energy Saving (HES) Scheme, later rebranded the Better Energy: Homes (BEH) Scheme. The methodology involved monitoring several homes immediately before and after retrofit alongside discussions with occupants. The examination focused on specific measures commonly introduced through the HES/BEH programme − cavity and external wall insulation. It has been found that a significant decrease in heat loss through the walls was measured in all cases. …
Flood Damage And Shutdown Times For Industrial Process Facilities,

Flood Damage And Shutdown Times For Industrial Process Facilities, Matthew Lane Flynn
LSU Master's Theses
The vulnerability of the Gulf Coast to inundation poses a real threat to both national security and the regional economy due to the concentration of the nation’s energy infrastructure throughout the waterways of the southeastern United States’ waterways. Mitigation efforts thus far have been qualitative and fail to provide raw, quantitative data to aid in the successful management of flooding liabilities. This paper proposes a novel approach to analyzing infrastructure susceptibility by means of a component-based approach to consequences posed by water-borne incursions. Systems are simplified to collections of components, each with a lowest-member elevation, thereby identifying the benchmark for …

Enhancing Project Management With Lean World Class Manufacturing In Construction, Jacob Randles
Electronic Theses and Dissertations
In construction, the goal of commercial projects is to turn a profit. This is achieved by minimizing inputs and maximizing outputs while building a product that meets the customer’s perception of value. Value is determined through pre-negotiated specifications, plans, and material quality. Even in U.S. military construction, the unit executing the construction wants to complete the task on time and on budget, which can be difficult to do. Studies on project completion showcase a surprisingly high rate of failure in reaching the aforementioned “on time, on budget” goal. It is important to understand the nuances and details of U.S. Army …

Slope Stability Enhancement Of An Upstream Tailings Dam: Laboratory Testing And Numerical Modelling, Yazeed A. Alsharedah
Electronic Thesis and Dissertation Repository
Mine tailings are the byproduct of mining activities, which need to be disposed of once the ore is extracted. They can be disposed of in either dry or wet forms. The latter is most common with the tailings being disposed of in the form of slurry inside retention structures. The retention structure may be a natural, manmade, or built dam, which is the case in most of nowadays mining locations. In this thesis, improving the stability of an upstream tailings dam using soil additives is investigated. The experimental phase of this study involved laboratory tests conducted to characterize mine tailings …

Use Of Personality Profile Assessments In The Construction Industry, Brian Richard Childs
Theses and Dissertations
Various industries are using personality profile assessments as tools to help reduce employee turnover. Employee turnover is a continuing challenge in the construction industry that has negative effects on construction companies. Research found that it was difficult to know if companies in the construction industry are using personality profile assessments as a tool to help reduce employee turnover. After understanding that other industries were using personality profile assessments in their hiring, promoting, team building and leadership development to reduce turnover, it was desired to understand if the construction industry was doing the same. This research performed a survey among the …

Comparative Analysis Of Buckling-Restrained Braced Frames In Eccentric Configuration (Brbf-Es) And Eccentrically Braced Frames (Ebfs), Peter T. Vayda
Civil Engineering Undergraduate Honors Theses
Continuing on the findings of “Using Buckling-Restrained Braced Frames in Eccentric Configuration,” by Dr. Gary S. Prinz, P.E., which determined that, from a performance standpoint, BRBF-Es could be a viable alternative for EBFs. A comparative analysis was conducted on the design procedures and initial cost estimates of BRBF-Es and EBFs. Upon designing four 12-Story buildings (two BRBF-Es and two EBFs), it was determined that BRBF-Es were easier to design due to the statically determinant system. The initial costs estimates of BRBF-Es; however, ranged upwards of 30% more cost than EBFs. Therefore, the initial investment of more intensive structural engineering design …

Subjective Perception Of Varying Reflection Densities In Room Impulse Responses, Hyun Hong
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
Reverberation time (RT) is a metric commonly used to describe room acoustic conditions, but different rooms which have the same reverberation time can have different reflection densities. Much less is known about how humans perceive different reflection densities and how sensitive humans are to changes in reflection density. Previous investigations in the existing literature have studied the upper limit of distinguishable reflection density using artificial impulse responses, but not with more realistic impulse responses simulated in room acoustic software or measured from real rooms. The aim of this dissertation is to investigate methods for quantifying reflection density from measured impulse …

The Application Of Industry Standards As An Alternative To In-House Proprietary Standards Within The Aec Iindustry, Robert Moore, Alan Hore, Barry Mcauley
Conference papers
The move from traditional 2D Computer Aided Design (CAD) practices towards Building Information Modelling (BIM) has witnessed some practices trying to adopt and update their own in-house CAD standards. These standards are wholly inadequate for working in a collaborative BIM environment and mean that they repetitively create and recreate local, non-reusable, non-interoperable solutions to the same problems, which leads to the employees potentially having to learn a new collaborative process every time they have to work with a new project team. Collaborative standards help teams produce information through a standardised process, so as to ensure the same form and quality …
