INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

W hitlatch Yeou-Shang Jenq Jason H su VI A dviser Department of Civil Engineering To My Wife and Children ii ACKNOWLEDGEMENTS The gratitude which I would like to express to those who made this study possible goes much deeper than prose could connote. My sincerest appreciation is extended to Dr. Zoltan Nemeth for his guidance, patience and insight throughout my academic life at The Ohio State University. To all other members of my advisory committee, Dr. Yeou-Shang Jenq and Dr. Jason Hsu, I would like to give special thanks for their unselfish contributions and persistent encouragement even at times when the focus of the study was still unclear. To Dr. Earl Whitlatch for his critical evaluation and suggestions on refinement. Dr. Frannie Humplick instilled confidence in me during the early stages of the study with the keen interest she showed. Her methodical overview made it easier to construct the framework of the study. To her I extend my gratitude. The study would not have been possible without the cooperation of the technical personnel of the Ministry of Works and members of the budget committee of the State Planning Secretariat, Guyana. The willingness with which they made the data available and the speed with which they responded to requests, deserve special acknowledgement. To the university of Guyana I am heavily indebted for affording me an opportunity to further my studies. Finally I would like to express special appreciation to my wife and children for understandably enduring three and one half years of single parent cohabitation while I pursued my academic goals.
