Is the current theory of construction a hindrance to innovation?

An explanation for the low innovation activity in const¡uction is put forward. The central argument is that the cur¡ent
theory of construction is one root cause for low innovation activity. Instead, an explicit and more powerful theory of
construction is needed for further imovation, which is 'to manage new ideas into good currency'. There are three main
mechanisms in the current tbeory of construction which are identified as causing this hindrance. Firstly, production theories
in general, as well as construction theories specifically, have been implicit. Therefore, it has not been possible ro transfel
radical managerial innovations, such as lean production, from manufacturing to construction at a theoretical level. Direct
application of this production template to construction has been limited due to the different context of construcrion in
comparison with manufacturing. Secondly, the current theoretical model of construction is based on the transformation
model of production. It is argued that the principles of this model are counterproductive, because uncertainty and interdependence
are abstracted away. This leads to fragmented and myopic mânagement and inflated variability. practical
examples show that these deficiencies and related practical constraints hinder rhe implementation of top-down innovations.
Thirdly, empirical research shows that âlso bottom-up innovations - systematic learning and problem solving - are being
hindered by the current theory. Thus, the advancement of innovations in construction requires that a new, explicit and
valid theory of construction is created, and business models and control methods are developed on the basis of that new
theory
