ABSTRACT Most often than not, project costs as estimated cannot realistically execute and deliver the project – an estimating inaccuracy called cost underestimation. Since cost estimates are the basis for decision making regarding project selection, underestimation lead to selection of project with significant cost risks. Researchers have so far failed to agree on the main cause of cost underestimation, therefore this research study is carried out to examine the problem of cost underestimat...
ABSTRACT This research work deals on efficient contract management and its effect on project delivery. The need for the research arose due to rampant project delays and abandonment in the country and their adverse effect on the national economy. Both primary and secondary data sources were used to obtain the data for the research work. A structured questionnaire based on the 4-point lickert scale was used to collect data from the respondents. The results of the analyses indicate that there...
ABSTRACT This study is aimed to investigate and analyze the implementation of constructability in project delivery process in the Nigerian engineering / construction industry using Rivers state as case study area.Data was collected through questionnaire and interview approach. Analysis of data was carried out with the use of SPSS V16.Results of data analysis revealed that although a high percentage of the sampled population are familiar with the term “constructability”,nearly alldo not h...
ABSTRACT As competitive strategies shift to the area of quality management, this research seeks to predict contributions of input variables to quality outcome. The research was conducted using 7-Up Bottling Company Plc; Aba. Data relevant to the study were secondary data from past company production records. However, observation of manufacturing processes was done in the course of the study to enhance understanding of production and quality control processes. A random sample was analysed int...
Software engineering projects (SEP) nowadays acknowledge the importance of incorporating many people, groups, and organizations with interest or requirements during project development phases for the realization of successful project. These groups who are collectively referred to as stakeholders are not limited to those who use it, rather those who build, test, operate, maintain, evaluate, and pay for it. One of the major concerns in SEP is the recognition and management of project stake...

ABSTRACT Materials Management in the Construction Industry in Imo State have been investigated. In order to reduce wastage of construction materials, the study focused on Success Level in Achieving Effective Materials Management as the Dependent Variable (Y) by introducing five Independent Variables (X1 to X5) thus (X1) Management of Materials; (X2) Skilled Professionals; (X3) Control of Materials; (X4) Inventory Build-up and (X5) Motivation of workers. Three indigenous construction compa...
ABSTRACT This study examines and analyses the salient factors that constrain work schedule performance and their contributions to the level of project time overrun in construction industries in Nigeria. The realization of project work schedule objectives is usually not achieved with certainly due to myriads of constraining factors encountered during the implementation stage of project life cycle. The survey method of research design was adopted. The primary data used in the study was ...
Abstract This study undertook a comparative analysis of direct government finance and public private partnership (PP) option for healthcare infrastructure development. The objective is to assess the cost, time and financing leverage effects of the two financing options. The Federal Medical Centre (FMC) Owerri was used as study location. Two identical building projects: Ward II funded through PPP and Ward 10 funded through direct government financing was used as case studies. A combination...
ABSTRACT The study evaluated the effect of cost, schedule, and quality parameters on the realization of building construction projects delivery via the traditional method and the partnering methods (design build and build own operate methods). A total of 5 traditionally procured projects, 5 design build projects and 5 build own operate projects making a total of 15 projects that were used for the study. Data set for the study were collected via the questionnaire and oral interviews from r...
ABSTRACT This research work investigates the effect of cost drivers on software cost estimation. Several models exist that provide one or more mathematical algorithms that compute cost as a function of a number of variables or cost drivers. There are also several other tools and techniques available to assist in creating software project cost estimates, they are still very inaccurate. Several authors in software development have given varied suggestions for these inaccuracies and ways...
