The Impact Of Cost Control Techniques On Construction Projects Delivery
1.1 Background Of The Study
It’s a known fact that the Nigerian construction assiduity continues to enthrall an important position in the nations frugality indeed though it contributes lower than the manufacturing or other service diligence,( Aibinu and Jagboro, 2002). The donation of the construction assiduity to public profitable growth necessitates bettered effectiveness in the assiduity by means of cost effectiveness and punctuality, and would clearly contribute to cost savings for the country as a whole. It’s also common knowledge that the perpetration of the construction design in the assiduity is generally accompanied with time detention and cost increase as well as proprietor dissatisfaction( Hafez, 2001).
In general most( if not each), construction systems witness time detainments and cost overruns during their perpetration phase( Koushki and Kartam, 2004). multitudinous experimenters, both in the developed and developing nations have also examined and linked the causes of time and cost overrun in the construction assiduity. Mansfield, Ugwu and Doran( 1994), for illustration performed a comprehensive analysis of most important factors responsible for design detainments and cost overrun in Nigerian construction systems. This analysis indicated poor contract operation, backing and payment of completed workshop, change in point conditions, dearths of accoutrements , design changes, subcontractors and nominated suppliers, other factors were price change inaccurate estimates, detainments and fresh workshop as factors responsible for design detainments and cost overrun.
A comprehensive bracket of causes of construction detainments has also been determined by Henesy( 1993). The bracket system included accoutrements , labour, outfit and fiscal constraints, as the main contributory variable to causes of construction time overrun. The list of major factors causing construction detention in Thailand by Ogunlana and Proumkunting( 1996) included the inadequacy of coffers inventories, customer and adviser failings and incapacity. Koushki and Kartan ( 2004) studied the impact of construction accoutrements on design time and cost in Kuwait and linked the design related variable affecting the on time delivery of accoutrements as material selection, time, type of accoutrements and their vacuity in the original request.
Time impacts are ineluctable on construction systems, primarily because of the oneness of each design and the limited coffers of time and plutocrat that can be spent on planning, executing and delivering the design.
Time factors are essential in all of design constructions undertakings. Construction systems have long been honored as particularly cost, time and threat- laden. Some of the time and cost factors associated with the construction process are fairly predictable or identifiable; others may be completely unlooked-for. The constructed design may not perform as anticipated because the proprietor may have unrealistic prospects regarding the delivery time of construction forcing contractors into unrealistic crap shoots, corner- slice or commitments that may not be realistic( Frimpong 2003).
Project success can be defined as meeting pretensions and objects as specified in the design plan. A successful design means that the design has fulfilled its specialized performance, maintained its schedule, and remained within popular costs. Project operation tools and ways play an important part in the effective operation of a design. thus, a good design operation lies in the operation tools and ways used to manage the design. Project operation involves managing the resources workers, machines, plutocrat, accoutrements and styles used. Some systems are effectively and efficiently managed while others are misruled, incurring important detention and cost overruns and negatively affecting the frugality( Frimpong 2003).
Assessing construction projects delivery time is critical in today’s request- driven frugality.
Problem Statement
Construction can be considered as a dynamic assiduity which is constantly facing misgivings. These misgivings and the numerous stakeholders in these kinds of systems, make the operation of costs delicate which accordingly causes cost overruns. thus, cost overruns are considered one of the most critical issues during the prosecution of construction systems( Chan, etal., 2004; Doloi, 2011).
As mentioned by Van Der Westhuizen and Fitzgerald( 2005), the presence of cost overruns can be a reason for design detainments or possible design failures. still this idea has been refuted by numerous authors who considered that design success depends on numerous other factors that should be assessed to conclude the success or failure of a design( Chan, etal., 2004). also, there have been numerous studies that suggest that the success of a design depends on the presence of certain critical factors which can also change depending on the ideal to be met( Iyer and Jha, 2005). In other words, some authors caught on that there are some critical success factors that help to ameliorate cost performance and help cost overruns.
Objects Of The Study
The main end of the study is to examine colorful cost control ways used in construction systems and the impact they’ve on design delivery. Specific objects of the study are
To identify cost control fashion constantly used by contractors in construction systems.
To examine problems encountered by contractors in managing construction design cost.
To determine the impact of costcontrol ways on the duration of construction systems.
Exploration Questions
In- order to guide the study and achieve the over stated exploration objects; the following exploration questions were formulated
What cost control ways are constantly used by contractors in construction systems?
What are the problems faced by contractors in controlling cost in the construction design process?
What impact does bring controlling ways have on the duration of construction systems?
Exploration Suppositions
Ho Cost control problems lead to design delivery failures.
Hi Cost control problems don’t lead to design delivery failures.
Ho Cost Control ways lead to construction delivery failures
Hi Cost Control ways don’t lead to construction delivery failures
Significance Of The Study
This study will be of significance to structure professionals and the general public because it would not only clarify but also produce mindfulness of the extent to which crunches in cost control ways can negatively affect design performance. The study will also help contractors, guests, advisers and all parties involved in construction systems about ways of perfecting their current system of cost operation and control.
The study will also be of great benefit for other pupil researchers who may want to venture into the same subject matter. Having gotten results- both empirically and theoretically, the study will serve as a foundation for unborn exploration studies.
Compass Of The Study
The study will cover some named volume surveyors from Owerri. All findings and recommendations from the study may not reflect the true view of the traditional places and changing places of volume surveyors as the experimenter couldn’t cover a wider area due to fiscal and time constraints.
Description Of Terms
Construction In the fields of armature and civil engineering, construction is a process that consists of the structure or assembling of structure. Far from being a single exertion, large scale construction is a feat of mortal multitasking. typically, the job is managed by a design director, and supervised by a construction director, design mastermind, construction mastermind or design mastermind.
Deliverable Deliverable is a term used in design operation to describe a palpable or impalpable object produced as a result of the design that’s intended to be delivered to a client( either internal or external). A deliverable could be a report, a document, a garçon upgrade or any other structure block of an overall design.
Design Operation this is the discipline of planning, organizing, motivating, and controlling coffers to achieve specific pretensions. A design is a temporary bid with a defined morning and end( generally time- constrained, and frequently constrained by backing or deliverables), accepted to meet unique pretensions and objects, generally to bring about salutary change or added value.
Time This is a dimension in which events can be ordered from the history through the presentinto the future, and also the measure of durations of events and the intervals between them.
Cost A cost is the value of plutocrat that has been used up to produce commodity, and hence isn’t available for use presently. In business, the cost may be one of accession, in which case the quantum of plutocrat expended to acquire it’s counted as cost.
Cost Overrun occurs when the final cost of the design exceeds the original contract value at the time of completion.
Good Cost Performance Design design in which the cost overrun of the design doesn’t exceed 10 percent of the original budget.
Poor Cost Performance Design design in which the cost overrun of the design exceeds 10 percent of the original budget.
