A Diverse Understanding of Value in the Building Industry 189
the practitioners with the most influence on the design solution are those
where value is most relevant, e.g. client, architect and consultant.
Based on this observation, the following zero-hypothesis was made.
H0 = respondents perceive value equally relevant for all parties. The
hypothesis was tested by calculating the relation between mean score of
the client and authorities. Since both categories are ordinal, Spearman’s
rank correlation coefficient should be applied (Forza 2002). The result of
the test performed with SPSS is illustrated in table 1.1.

Spearman’s rho is very close to 0, which means that the two variables are
not correlated. The zero hypothesis can be rejected, which in practical
terms means that when the client receives a high score from a respondent
the authorities do not. Hence, value is not equally important to all
participants of building projects.
Value Does not Equal Price
When talking to practitioners within the building industry, it is sometime
observed that some tend to think that value is related to price.
Theoretically, it is acknowledged that value is often measured in a price
relation. To test this, question B1 asks “In a building project value equals
price.” When looking at the answers to this question, there seems to be a
diverse perception. The mean score is 2,79 ±1,06, which illustrates that
there is a tendency to reject the relation, but the standard deviation is high.
It would hence be relevant to view the answers in relation to the
respondents’ company type.
