Characteristics of the Respondents
It is observed that about 23%, 18% and 14% of the respondents were quantity surveyors, builders and estate valuer respectively while engineers and architects that responded to the questions were about 22%. The mean year of working experience of these respondents was calculated to be 9.83 which could be considered appropriate for the study. As expected, all the professionals were members of their professional bodies in that the frequencies of the professionals correspond with that of the professional bodies.
However, majority of these professionals are corporate (Associate or members) members (about 46%) followed by graduate members with about 37% while probationers and fellows were about 14% and 3% respectively.
On the geographical zones that the respondents have executed one or more projects, all the respondents have been involved in project located in the South-West region as expected and this is followed by South-South and South- East respectively. It could be concluded that about 41% of construction professionals in Lagos state i.e. the respondents have participated in other projects located in other geographical zones of the country.
Performance of Nigerian Quantity Surveyors
Hypothesis was generated in order to test if there is a variance in the ranking of performance of Nigerian quantity surveyors by various groups of professionals as follow:
Null Hypothesis (H0):
There is no significant agreement between quantity surveyors,
architect, estate valuer, builder and engineers in ranking the performance of Nigerian quantity surveyors based on the areas of competencies of quantity surveyors.
Alternate Hypothesis (H1):
There is significant agreement between quantity surveyors, architect, estate valuer, builder and engineers in ranking the performance of Nigerian quantity surveyors based on the areas of competencies of quantity surveyors.
The result as presented in table 4 revealed that there is no significant agreement between the ranking of quantity surveyors, architect, estate valuer and builders while there is agreement between quantity surveyors and engineers in the ranking.
Table 5 revealed that Nigerian quantity surveyors perform better in valuation, project Management and measurement from the view of quantity surveyors. At the lower end is insolvency and mapping and this may be as a result of little or no understanding of the term “mapping”.
The architects ranked personal and interpersonal skill and valuation 1st and 2nd while estate surveyors believed that Nigerian QS performs better in measurement and economics of construction. Professional practice and data, information and information technology were tied in the 1st position by the builders while engineers were of the opinion that QS perform better in valuation and construction contract practice.
On the general opinion, valuation, project management, construction contract practice and measurement were ranked 1st, 2nd, 3rd and 4th respectively while property investment Journal of Building Performance ISSN: 2180-2106 Volume 1 Issue 1 2010 University Kebangsaan Malaysia

Discussion of Findings
In ranking the performance of Nigerian quantity surveyors based on their areas of competencies, the study revealed that there is no agreement in the ranking of performance of Nigerian quantity surveyors between quantity surveyors and other professionals except the engineers and this could be justified since an individual will always want to rate himself above normal while others will either rate normal or below normal.
Diversities in experience, knowledge, training and working relationship of these construction professionals with quantity surveyors could also be reasons for the difference. Valuation, construction contract practice, project management, measurement and procurement management are areas of competencies where quantity surveyors perform better.
The traditional role of Nigerian quantity surveyors are centred on these areas and this is supported by Babalola (2006) where it was stated that the quantity surveyors can be said to be the client’s building economist, a role incorporating all the earlier mentioned areas of competencies. Selinger and Stamler (1983) believed that bill of quantities is an essential part of the financial system of many construction projects and its preparation is the major role of the quantity surveyors. In Jagun (2006) opinion, many quantity surveyors are mostly involved with measuring and valuing of construction work being carried out under a traditional building contract.
Nkado (2000) stated that three of the traditional core competencies of quantity surveyors, namely: procurement and financial management, economics of construction and construction contract practice are among the five most important competencies currently required of quantity surveyors and Nigerian quantity surveyors are found to be performing above average in these areas. Taxation and grant allowance and facilities management are areas of neglect by Nigerian quantity surveyors and this underscore the reason for their performance.
Data, information and information technology is ranked 12th and this is supported by Oyediran (2005) where it was stated that majority of quantity surveyors in Nigeria have limited knowledge of information communication technology (ICT).

The study has been able to explored areas of competencies of quantity surveyors and it was discovered that Nigerian quantity surveyors are performing above average from the perception of all the construction professionals that participated in the study. The study also suggests the need for Nigerian quantity surveyors to improve in the areas of insolvency, taxation, property investment funding and mapping.
The following recommendation are made because the result are finally recommended a need for personal improvement by quantity surveyors in Nigeria – especially the older ones- in order to keep them abreast with the current trend in the construction industry.
This paper is part of a larger research work on “Competencies of Nigerian quantity surveyors as value managers” in fulfilment for the award of Masters of Technology (M.Tech) degree in quantity surveying.
