STUDY INTO THE EFFECTS OF TIMELY DELIVERY OF CONSTRUCTION PROJECT ON ECONOMIC DEVELOPMENT OF NIGERIA
Chapter one
INTRODUCTION
1.1 Background of the Study
Time impacts are unavoidable for construction projects, owing to the unique nature of each project and the limited resources of time and money available for planning, executing, and delivering the project.
Time issues are inherent in all project construction endeavours. Construction projects have long been recognised as being exceptionally expensive, time-consuming, and risky.
Some time and cost aspects connected with the construction process are somewhat predictable or traceable, while others may be completely unexpected.
The completed project may not operate as expected because the owner may have excessive expectations about construction delivery time, leading contractors to take unrealistic risks, cut corners, or make unrealistic commitments (Frimpong 2003).
Project success is defined as achieving the goals and objectives outlined in the project plan. A successful project has met its technical objectives, adhered to its timeline, and stayed within budget.
Project management tools and procedures are critical to the successful execution of projects. As a result, good project management relies on the management tools and strategies utilised to manage the project.
Project management entails overseeing the resources—workers, machines, money, supplies, and procedures used. Some projects are properly and efficiently managed, whereas others are mismanaged, resulting in significant delays and cost overruns and severely impacting the economy (Frimpong 2003).
In today’s market-driven economy, assessing construction project delivery times is crucial.
To boost the economy and maximise the long-term return on this public investment, government agencies have recently begun to use new types of contracting methods that are designed to achieve multiple project goals, such as reducing construction costs and duration while increasing quality.
In recent years, numerous departments of transportation in various states have begun to adopt novel highway contracting practices, including: Bidding on time, i.e., to foster competition among contractors to minimise project duration (Holt et al2000); Contract terms that provide financial incentives to minimise construction duration.
Nighttime construction aims to reduce service disruption and project time by mandating contractors to work during off-peak nighttime hours, while warranty contracting aims to improve construction quality by holding contractors accountable for the facility’s performance after project completion.
These new and growing contracts increase the pressure on construction industry decision makers to find an optimal/near-optimal resource utilisation plan that reduces construction time while boosting quality.
This creates new and pressing demands for improved resource utilisation models capable of optimising the numerous and competing goals of building time, cost, and quality.
Significant research advances have been made in the field of maximising construction resource utilisation. This resulted in a number of optimisation models. These models can be classed according to their optimisation objectives as models that sought to:
• Reduce project duration and/or optimise resource utilisation.
• Use time-cost trade-off analysis to reduce time and expense in non-repetitive construction.
• reduce time and/or costs for repetitive building.
While the following research study aims to make major contributions to the field of optimising construction resource utilisation, there has been little or no published research on multi-objective models for optimising construction time, cost, and quality.
1.2 STATEMENT OF THE PROBLEM.
Misallocation and misconception of the time factor in building projects have led in the Nigerian government spending more than is necessary for several projects.
Improper time assessment can also result in additional expenditures in the form of delays, which leads to poor utilisation and increases social and economic costs.
Are contractors using the best resources to complete projects in Nigeria? Do they mobilise the necessary resources within the time range specified by their contracts? How can short and/or longer time periods affect project costs? Are there any solutions to these situations?
These are some of the circumstances that encouraged the researcher to conduct a thorough analysis of the cost and time implications of public sector construction projects in Nigeria.
1.3 GOALS OF THE STUDY
The study’s primary goal was to analyse the effects of timely construction project delivery on the Nigerian economy, but it also had the following objectives.
1. Determine the extent to which timing issues have influenced the construction of public sector projects in Nigeria.
2. To investigate the shift in contractors’ perceptions of time implications on public sector building in Nigeria.
3. Determine the relationship between timely delivery of construction projects and Nigeria’s economic development.
1.4 RESEARCH QUESTIONS
To meet the study’s objectives, the researcher employed the following research questions:
1. How do time factors affect project construction in Nigeria?
2. Has the opinion of contractors regarding time constraints in project building altered in recent years?
3. What is the relationship between timely completion of construction projects and economic progress in Nigeria?
1.5 Research Hypothesis
Ho: There is no significant association between timely construction project completion and Nigeria’s economic development.
Hi: The timely delivery of construction projects has a substantial impact on Nigeria’s economic progress.
1.6 Significance of the Study
Every building contract allocates time between owners and contractors. As a result, the findings of this study will help to inform better project interactions and communications, as well as improve construction administration procedures between owners and contractors.
The findings would also improve and broaden the time frame for a wide range of hazards that could occur during the design and construction phases of a project, resulting in better and more sensible design specifications.
1.7 SCOPE OF THE STUDY
The researcher will focus the study on the effects of timely delivery of construction projects on the Nigerian economy, using replies from chosen project supervisors from Julius Berger Nigeria Plc and Marlum Nigeria Plc in Uyo, AkwaIbom State as a case study.
The researcher’s findings and recommendations may not be applicable to general analysis because the researcher was unable to evaluate multiple construction projects due to time and financial restrictions.
1.8 Limitations of the Study
Construction of projects in the public sector has taken on substantial roles, necessitating an assessment of the cost and schedule consequences of project construction in order to meet overall project objectives.
Julius Berger Nigeria Plc treats historical project schedule and duration data as confidential, making it impossible to collect data for this study. Data collection and analysis were thus limited to information obtained from project supervisors in the field of project construction.
1.9 Definition of Terms
1. Economy: An economy is a region’s or country’s economic system, which includes the production, distribution, trading, and consumption of products and services. An economy is the total amount of all value transactions between two agents, such as one individual to another, or between groups of individuals, such as organisations to other organisations, or between one nation and another.
2. Construction: In architecture and civil engineering, construction refers to the process of building or assembling infrastructure. Far from being a single activity, large-scale building requires human multitasking. Typically, the job is handled by a project manager and overseen by a construction manager, design engineer, construction engineer, or project architect.
3. Deliverable: In project management, a deliverable is a tangible or intangible thing created as a result of a project and intended for delivery to a customer (either internal or external). A deliverable can be a report, a paper, a server upgrade, or any other component of a larger project.
4. Project management is the discipline of planning, organising, motivating, and regulating resources to achieve certain objectives. A project is a temporary undertaking having a clear beginning and finish (generally time-limited and frequently constrained by money or deliverables), undertaken to achieve certain aims and objectives, typically to bring about beneficial change or additional value.
5. Time: This is a dimension in which events can be ordered from the past, present, and future, as well as a measure of event durations and intervals.
