Measuring Partnered Project Performance, Douglas D. Gransberg, Howard L. Reynolds, Jack Boyd
Douglas D. Gransberg
The results of a study of over 400 projects completed by the Texas Department of Transportation over 5 years are presented. The objective was to compare the performance of construction projects on which formal partnering agreements had been executed with projects that had been completed without partnering and measure the benefits due to partnering. The data was collected by 20 different aspects, from cost and time growth to the amount of previous experience.
Epoxy-Terminated Self-Assembled Monolayers As Molecular Glues For Polymer Layers, Duangrut Julthongpiput
Epoxy-Terminated Self-Assembled Monolayers As Molecular Glues For Polymer Layers, Duangrut Julthongpiput
Masters Theses
Dense, homogeneous, and complete self-assembled monolayers (SAMs) with epoxy surface groups were fabricated from epoxysilanes to serve as a template for chemical anchoring of polymer layers. A combination of scanning probe microscopy, ellipsometry, XPS, X-ray reflectivity, and contact angle measurements was used to study their morphology and surface properties. Self-assembly of epoxysilane molecules resulted in the formation of homogeneous SAMs 0.85 nm thick with the rms surface roughness 0.2 nm. Epoxysilane SAMs were truly monomolecular films with a virtually normal molecular orientation of densely packed molecules, which were firmly attached to the substrate.

Conform- A Computerized Job-Built Concrete Construction Formwork Design, Kajpong Pongponrat
Conform- A Computerized Job-Built Concrete Construction Formwork Design, Kajpong Pongponrat
Masters Theses
Economy in formwork design depends partly on the ingenuity and experiences of the form designer, whether a contractor or an engineer. The cost of formwork is significant, generally amounting to anywhere from 40% to 60% of the cost of a concrete structure. Judgment with respect to the development of a forming system could both expedite a project and reduce costs. The present paper addresses the development of CONFORM - an interactive menu driven PC based job-built concrete formwork design. The system is developed using Microsoft Visual Basic 6, Access 97 database, and Word 97, where a perfect integration of these …
Quantitative, Non-Destructive Calibration Of Scanned Probe Microscope Cantilevers, John Hazel
Quantitative, Non-Destructive Calibration Of Scanned Probe Microscope Cantilevers, John Hazel
Masters Theses
Principles of surface science and engineering are applied to determine scanned probe microscope cantilever spring constants. The bi-component gold-ceramic cantilever composition is modeled analytically. Finite element analysis is applied to simulate deflection behavior of the probe tip. Data from experimental determination of resonant frequency are employed to infer material characteristics. Combination of the results from these three procedures is employed to infer material characteristics. Combination of the results from these three procedures is used to produce a spring constant assessment within 10% of actual values. An additional convenient program for assessment of scanning probe microscopy cantilever spring constants is developed …
Intellicrances – A Neural Network-Based Crane Selection System, André T. Mund
Intellicrances – A Neural Network-Based Crane Selection System, André T. Mund
Masters Theses
Due to the central role of cranes in construction operations, specialists in the construction industries have cooperated in the development of structured methods and software for crane selection. Most of these software tools are for crane model selection and query the user for the type of crane to be used. Although research produced some fuzzy logic and expert system-based methods for crane type selection, no integrated systems that handle both crane selection phases are available.
IntelliCranes, a prototype integrated crane selection tool, assists in both crane type and crane model selection based on a set of inputs describing the construction …
Individual Housing Choices Among Air Force Members, Michael J. Johnson
Individual Housing Choices Among Air Force Members, Michael J. Johnson
Theses and Dissertations
Air Force members have three different housing choices: live in MFH, rent in the local community, or buy a house in the local community. A set of six constructs (Housing Attributes, Safety, Pet Importance, Location, Military Housing Perception, and Community) that encompass members' considerations is developed and analyzed. The data was extracted from a survey that was specifically designed to illicit the relative importance of each construct during the housing decision making process. Each construct was measured using a Likert scale score. Statistical analysis was performed to determine the overall Likert mean score for each construct. Using the Likert mean …
Analysis Of Cost Growth In Us Air Force Base Support Function Contracts, James S. Romasz
Analysis Of Cost Growth In Us Air Force Base Support Function Contracts, James S. Romasz
Theses and Dissertations
The United States Air Force (USAF) has outsourced a significant portion of their activities defined as commercial activities and plans to aggressively outsource more in the future. The USAF outsources its commercial activities in the form of multi-year contracts to the private sector. Cost growth (either negative or positive) has been experienced by most of these contracts. This research effort performed a review of current literature and used statistical analysis to clarify the issue: what are the causes, and extent of cost growth in USAF base-support-function contracts?. From the literature, it can be concluded that changes to the statement of …
Management Of Change In The Irish Construction Industry, Louis Gunnigan
Management Of Change In The Irish Construction Industry, Louis Gunnigan
Masters
Ireland is changing and this change is nowhere more apparent than in the rapidly growing construction industry. The industry is being forced to change at an unprecedented pace. This thesis sets out to develop a framework on which construction organisations can approach and manage change.
It examines the issues that will cause change, reviews the available literature to find how change can be managed and controlled, and develops a model for guiding change programmes in the construction industry. The model is tested against three case studies, the first two of which are concerned with finding increases in efficiency and demonstrating …
A Study Of Factors Affecting The Implementation Of Iso 9000 In Taiwan's Construction Industry, Chuan-Chen Hung
A Study Of Factors Affecting The Implementation Of Iso 9000 In Taiwan's Construction Industry, Chuan-Chen Hung
Dissertations and Theses @ UNI
The purpose of this study was to determine the attitude of Taiwanese construction companies regarding the adoption and implementation of ISO 9000. This was accomplished by conducting a survey to investigate the perceived factors affecting the intention to adopt ISO 9000 and its successful implementation.
The survey instrument was developed through the review of related literature as well as through validations. One hundred eighty (180) construction companies were randomly sampled from the 1998 Membership Directory of the National Construction Association of the Republic of China (Taiwan), which consisted of 60 Type-A, Type-B, and Type-C construction companies. In total, 62 respondents …
