1 ) 1BACKGROUND FOR THE STUDY
The construction industry has its own features which in turn set that apart from additional industries and which highlight the need for professional management (Bamisile, 2004). According to Oyegoke (2006), the development project in the 21st century is now a more intricate process that spans various phases, is usually technologically powered, has many stakeholders, involves new types of clients, financial situation and job organizations. It has resulted in within construction methods that impact the structure in the industry, the roles in the parties, plus the procurement methods employed. Ibrahim (2003) recognized that the building process is definitely divided into three phases; Job conception, Project design, and Project structure. Ibrahim (2003) went further by defining; Project conceiving is the identification of a require that can be pleased by a physical structure. The project style phase translates the primary principle into an expression of a space form that could satisfy the client's requirements within an optimum monetary manner. The development phase creates the physical form that satisfies the conception and permits the realization with the design. Bamisile (2004) opined that the vocations in the structure industry are many and diverse in characteristics and thus this individual identified this as the pros involved in the sector: 1 . Architects
2 . Building contractors
3. Engineers- (Geotechnical, Strength, Civil, Physical, Electrical etc) 4. Real estate Surveyors and Valuers
5. Quantity Surveyors
six. Town planners
Bamisile (2004) summarized the roles of such professionals as, planning, design, costing, creation, management and general stability and serviceability of set ups. Cost has its confirmed importance as the prime factor for task success. It absolutely was against this backdrop that Oyegoke (2006) determined cost, range, time and top quality as the customer expectation on a construction task. Thus expense can be said to become a major element in determining the success or the failure of the project. Even so Aina and Ikpo (2008) are of the opinion the fact that success of any development project is usually measured by matching the actual duration and cost with the planned devoid of prejudice towards the designed or perhaps anticipated final quality. It was further responded when Barclays (1994) while cited in Ibrahim (2003), opined that building task can only end up being regarded as effective if it is delivered at the right time, at the ideal price and quality criteria, and provides your customer with a dangerous of fulfillment. But this is argued which a project or else completed will not be regarded as a prosperous endeavor till and except if it fulfills the cost limits applied to this. In spite of its proven importance of cost, it is not necessarily uncommon to get a construction project failing to achieve its aim within the specified cost. Irrespective of building projects failing to achieve its goals, there has been an increase in the cost of building construction in Nigeria which was determined when Ajanlekoko (2003) said that Development costs in Nigeria happen to be among the greatest in the world. In respect to Elchaig, Boussabinaine and Ballal (2005), most of the significant factors influencing project costs are qualitative such as customer priority in construction period; contractor's planning capability, purchase methods and market conditions including the standard of construction activity. Ajanlekoko (2003) went additional by saying following; design inadequacies, number of contractors, past due appointment or perhaps exclusion from the quantity inspector, market pushes and Govt action, and so forth as factors responsible for the high cost of development projects in Nigeria. However , Oyegoke (2006) through the physique below determined management on the part of the client for the success of any building projects. STYLE PHASE
