ABSTRACT The Reliability Analysis of a Prestressed Concrete Beam (PCB) was presented using First Order Reliability Method and Eurocode 2 procedures to carry out the analysis. The results show that the safety of the PCBin bending decreasedfrom 2.9 to 1.0 and 3.1 to 2.6 as prestress force and the depth from the extreme compressive fiber to the... Continue Reading
ABSTRACT In the sense that the materials involved in this project were capital intensive more especially cement, so in carrying out the work one must have to be careful in the selection and collection of materials to be used in the casting of the concrete. The materials used are coarse aggregate (granite) fine aggregate (sand). The coarse... Continue Reading
PREFACE This is presentation of information on the detailing of structural members in Buildings. Structural detailing is a branch of structural work that transposes the ideal or works of a Structural Engineer in working drawings for easy utilization in the building construction works. Working drawing are produced by an... Continue Reading

CHAPTER ONE INTRODUCTION 1.1 Background of the Study Fluoride is one of the very few chemicals that have been shown to cause significant effects in people through drinking-water. Fluoride has beneficial effects on teeth at low concentrations in drinking-water, but excessive exposure to fluoride in drinking-water, or in combination with... Continue Reading
ABSTRACT The current extensive use of low quality aggregate in Nigerian road for engineering applications is of concern because their appear to be a level of ignorance surrounding their existing properties and implications. This project was conceived for the purpose of comparing the crushed aggregate deposits in Isi-Agu Abia State and mac-Daniels... Continue Reading
PREFACE In structural detailing, the project is initiated by the structural engineer. The architectural drawings are prepared by the architect to the required scale and specification given to him by the client. The structural engineer designs the structural frame work of the building and specification required such as slab, beam, column and... Continue Reading
ABSTRACT This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage... Continue Reading
ABSTRACT It has been clearly identified that one of the agent that easily deteriorate building structure, weaken the strength of the component of building and shorten the life-span of building is “DAMP”, which may occur in different dimension therefore, this project is centred on causes of damp, prevention of damp and the necessary treatment...

Abstract In countries where industrialization is on the rise there is a corresponding increase in waste production resulting from industries which eventually upsetsthe environment and community for which they provide. While most of these waste generated are hazardous and should be managed, others could be put to appropriate use either directly or... Continue Reading
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY AND ORGANIZATIONAL PROFILE Seeley (1997) described the construction industry as one of the most important sectors of the economy, which integrates a wide variety of skilled and unskilled professionals. These professionals engage in the provision of goods and services ranging from... Continue Reading
ABSTRACT A lateritic soil classified as sandy clay or (CL) and A-7-6 (5) according to Unified Soil Classification System (USCS) and AASHTO classification system respectively,was treated with up to 10% pulverized steel slag (an industrial waste product) by dryweight of soil. Elemental and chemical analysis of the steel slag was determined using... Continue Reading
[APPLICATION OF HENRY SCHEFFE’S AND OSADEBE’S CONCRETE OPTIMISATION THEORY] Abstract Sandcrete blocks are prismatic units manufactured from lean (sand-cement) mortar mixes and are the predominant walling materials used in buildings in Nigeria and other countries.... Continue Reading
ABSTRACT Groundwater hydrology may be defined as the science of the occurrence distribution, and movement of water below the surface of the earth. Geochydrology has an identical connotation, and hydrogeology differs only by its greater emphasis on geology. Utilization of groundwater dates from ancient times, although an understanding of the...
