Sammanfattning
While the grade of innovation in a variety of industries has been on a steady rise, the construction industry have been criticized for failing to keep pace, pushing the need for new innovative ways of working. In regards to the design phase, Skanska applies different techniques and practices in order to develop models and drawings, and changes made to the design have a major impact on the aspect of both cost and time. In reinforced structures, even the simplest of changes, such as adjustment of width, lead to a necessity of additional complex revisions of reinforcement. The Current way of working, require remodelling major parts when these changes occur. In the desire to streamline this process, new software that enables parametric design, is challenging the status quo by linking elements to each other, and as a result, creating the dynamic environment needed in current time. Through studying theory and collection of empirical data, a script prototype was created through Grasshopper, enabling the creation of a reinforced parametric retaining wall following a double-curved road line. This study showed that parametric design has potential to be included into current work flow at Skanska. Initially requiring a higher investment in form of time and money compared to traditional modelling, scripts and parametric models can be re-used, leading to fast returns once another similar project is completed. Concluding, the undisputed edge that comes with parametric modelling over the classical design process, has an opportunity to revolutionize industry in the similar manner to BIM at the beginning of the decade. Overseeing the future, designers and engineer would take on more managerial role, coordinating the software and develop new scripts.
