Influence of Codesign as a Cocreation Strategy on Constructability (Among Sri Lankan Architectural and Engineering Design Start-Up Practices)

Abstract

This research looks at the influence that codesign has on the constructability of a project and how the client’s knowledge impacts this relationship. Client knowledge is explored as a mediator. Further The factor that gave the largest contribution to codesign was the form of facilitation with a mean of 1.59, which was closest to the strongly agree point on the scale (number 1 was assigned to Strongly agree). The overall mean value of codesign was 1.82. Knowledge management gave the largest contribution towards constructability with a mean of 1.61. The overall mean of constructability was 1.70. The mediator, client knowledge had an overall mean of 2.10 with experience having the largest contribution with a mean of 2.08. Four hypotheses were tested. Hypothesis 1 was accepted since the correlation was 0.633, and its significance was 0.000, with the regression model fitting by 40.1%, showing that there was an impact on constructability from codesign. Hypothesis 2 was to test whether codesign and client knowledge were related, and it was proven, since correlation is reported to be 0.432 and its significance is 0.000, with the regression model fitting by 18.6%. Hypothesis 3 tested the relationship between client knowledge and constructability. It was also accepted in the correlation is reported to be 0.453 and its significance is 0.000 with the regression model fitting by 20.6%. Further, all factors in the three variables were validated through cross validation via thematic analysis, except for access to information. This could be because the client may not be able to interpret the information on their own. Hypothesis 4 investigated the mediator and an z value of 2.26 with significance of 0.000 indicates that client knowledge significantly mediates the relationship between codesign and constructability.
