a systemic approach to limiting factors FIELD OF ANALYSIS success of the Project Management in Construction Nigeria.> SUMMARY

The study analyzed the materials as part of the direct and indirect factors limit the success of the management of public projects and private sector construction in Nigeria with a systemic approach. This study is very relevant, since any constraint on the success in the construction industry has a significant effect on overall economic growth of the nation. Analyses of the data were calculated on the basis of data on subjective factors indices relevance of attributes. Factor analysis was used to reduce the potential for less, but each variable. The results of the analysis of important factors that contribute to development of a computer model and an advanced project management, equipment such as an effective tool for monitoring of projects in addition to time and cost variables are.

user among the top four to twenty economic sectors in terms of rank could be inter-sector. The importance of this sector as an agent of development by its ability to deliver improved employment for the teeming population of the nation. To this end, therefore, can not overestimate the strategic importance of the construction industry in a growing economy like Nigeria as we have seen that in the name of the industry for a significant proportion Product nation GDP and employs a large proportion of the workforce. The construction industry is an important index as a factor in social and political integration of the company and is considered one of the most important financial areas of developing countries. The construction industry seems to be the cornerstone and the foundation of rapid economic growth of any nation (Bhavesh, 2006). This is confirmed by the fact that the capital for most projects of Nigeria account budget for more than 40% of the total projected spending in annual federal and state budgets, and in the development of various nations stressed rolling plans. The proceeds from the construction industry is not required for the services they create for trade and industry have a structural basis. According to Eric, 2003, “The industry is likely to remain an important area of development activity that the need for the provision and renewal of infrastructure are becoming increasingly important in the coming years.”

This study is important factors limiting the successful management of construction projects in Nigeria. The success of the project as a system of constraints are interrelated and have a significant effect, individually and collectively on both public and private sector economy.

purpose of the “STUDY

The study aims to identify and analyze documents limiting factors for the success of the project management and public private sector in Nigeria. The analysis reflects the strength of the individual factors and the speed with which it concerns the failure, neglect, and decay of construction projects in Nigeria. The result of the findings, if applied, should reduce the speed, fail in the projects in Nigeria, if not eliminate even.

METHODOLOGY

The data analysis was done by direct and indirect sources. A format of five-point Likert scale was in the design of the questionnaire. Factor analysis was used used to the variables to fewer, but in each other to reduce variables. The ANOVA was used to the differences in the level of relevance of these factors, which prevent to confirm the success. The analysis of the cost constraints in the construction of residential buildings Ten IMO Secretariat Owerri by state concentrated ten enterprises of different structure, is the construction of Onitsha Owerri road still under construction and Oceanic Bank building along Douglas Road, Owerri, all in eastern Nigeria, West Africa Sub-Region. analytical formula is RRId = ?

However, the building materials available choices are many, are some new materials and were not tested. Strict rules are now required, for example to the requirements of environmental protection just right. Construction methods over the years by a single layer of stones and concrete blocks, demanding and complex steel structures, both in situ produced and changed. These methods require different management systems approach that of the conventional methods could face.

model search

The model in Figure 1 consists of the direct and indirect variables developed a holistic approach to solution to the problem of successful project management within the construction industry in Nigeria. This study is based on the analysis of the important factors, based presented as a subsystem of the system. The arrows show the model how the variables are inter-and intra-dependent. This shows is that every factor that affects a variable subsystem is always an impact on all other factors of this system and to other subsystems.

It’s interesting that define four of the six attributes that these dimension related only to the initial definition phase of the project, while only two relate to the other stages. They are “fluctuating material” and “Attitude of the project team to manage the devices. The second feature is also very important in the definition phase, because to maintain the attitude of the customer and the project team, the unit at an early stage clear influence on the achievement the project goals. The attitude of the customer and the project team to inventory management is very important. fluctuating cost of materials is another variable, the fee in the first sector. The materials can be purchased in bulk, payment and terms of payment or non-payment of staff turnover at the beginning integrated planning in the design phase. The second factor as “effects of variation material costs, delays and material requirements identified unprofitable design” is defined by five variables, including two positively charged, while three of the negative charge on the factor of 4 variables have factor loadings greater as 0.5000, while a variable fee of less than 0.5000. These variables are: the frequent change orders, delays, reduce debt, the economy of design and cost control implementation stage. This factor explains 12.1% variance explanation Self-value of 2.24. The frequent change orders and variations are provided in Material fourth.Factor 2 Variation of direct and indirect effects on the waste materials. Directe, that the quality of materials, labor and plants are affected or altered indirectly It also has a disturbing impact on the schedule, the impact on the costs further. This variable is endemic in public sector construction in Nigeria, has its roots in the inadequate definition of the scope in the design phase and therefore the factors described above in connection stand.

the dominant factor, say 33% of the variance to 27.7% in the public sector compared. But unlike the public sector, which has charged 10 variables, 16 variables of this factor on the 19 variables. The public and private 10 common variables on the dominant factors are loaded. equipment planning during the planning phase of the higher burden in the private sector, the importance of these variables shows in this sector. planning for effective material at an early stage is a requirement to stay at in the budget, when all the factors that determine the cost of the implementation phase will be considered and made provisions for them. However, there is the tendency of members of the project team deliberately under-estimate for the content of a project for a train before approval as a strategy of listing. from the factor analysis of the private sector, the second factor has three variables loading out two negative and one positive. The variables are negatively charged “frequent change orders / changes in physical and financial effects” and construction delays “on the basis of the unavailability of products ordered. The positive variable loading is “planning and control in the planning phase.”

The first part of the table shows the comparison between the public construction costs in relation to the key variables. The 10 variables for both sectors loads on the factor 1, which means that expenditures of generally similar show in 14 19 variables. The second factor is load up six variables and five others moderately high. The dependent variables are defined, the highest variation in material and labor costs of the plants (inflation). The variable is a very important factor causing physical constraints in public buildings. The nearest shop is very variable, followed by poor planning Change Orders and frequent changes in their financial implications. Construction delays and inadequate or incomplete design were loaded approximately equal to 0.59939 0.59243 and in each case. The variable that is least loaded this factor is critical and crucial issues affecting the availability and use of materials. Factor 2 is called “inflation, changes, and poor planning.” The comparison with the corresponding factor 2 (main factors), there are five variables for both factors. Factor 3 has four variables loaded on to two variables loading on factor 3 with the most important factors. The four variables are included the cost of crude error estimation, housing material loss caused by project staff, ambiguous specifications of materials at the construction rate interest on loans for the purchase of materials. The variable factors, for both the higher interest rates. This factor is called “interest rate, attitude and effectiveness of cost control,” The fourth factor is defined by only two variables, the lack of established methods to control the cost of the acquisition of materials. The corresponding factor of four of the most important factors is only one variable loading on it (unforeseen circumstances), so there is no common variable between the two factors. The fifth factor is also defined by two variables, unforeseen circumstances, the likelihood of unforeseen events in the area of risk, the employer and corruption. It is interesting that the factor 5 on the main factors that corruption is the only variable in this store.

s devices, I do not hit you as to the acquisition by the costs must be considered. The four direct factors of time, cost, quality and merchandise connected, are mutually dependent and must be important factors that will review the success of any construction project regardless of the scale construction. We know that the project participants, that prevent the delay in material procurement, inventory practices, etc., the occurrence of epileptic activity can and always on costs in all its ramifications. In a long-term health effects of building materials can affect the value of a property, such as the integrated use of asbestos in the roof and the ceiling. In addition, the inability to identify the climatic impact of some local and imported materials is undoubtedly impact analysis built on the maintenance of the structure. Some materials occurring during the process of implementation of the proposed construction and will certainly affect the construction time, cost and quality of work.

Recommendations

Specifications of materials and analysis are considered an important index in evaluating project proposals. There should be no ambiguity in the material specification in the design of the project, especially for complex ProSales be. Project participants should see significant factors in the immediate factors that are closely monitored the implementation of the project must succeed. The result of this analysis of the material factors lead to the development of a computer model and a construction project management software advanced software, include the handling and material substitution as an effective tool in monitoring the projects, alongside with the time and cost of the project

Computer-based management techniques must be used in the analysis of the hourly costs, monitoring and smoothing during the project implementation activities.

A project manager should be appointed early in the lifecycle of the project, managed from start to finish. This project manager in conjunction with members of the design team should define the scope of the work in detail with regard to alternative materials.
