The complexity and technology used in current projects have lead to a specialization of activities that results in a fragmented approach to design and construction, to the point that the design leaves all of the problems related with construction in the contractor´s hands. Different authors have reported that issues related to quality and delays in construction projects are caused by design deficiencies. Furthermore, projects overruns coming from design depict the most significant budget increases.
However, locally, there is no indication of the awareness or application of this concept. Therefore, this research´s objective was to determine the extent that design and design-build firms in the city of Merida, Yucatan apply the principles of constructability in the design phase of building projects, as well as to identify the factors that promote or inhibit the implementation of these principles.
Based on the information provided by the interviewees, the average application for each constructability principle was determined, with which the overall level of application of constructability was ultimately obtained. The results show that even though local construction practitioners are unfamiliar with the constructability concept, a relatively high overall level of application was obtained: 67% according to designers and 66% according to contractors. Furthermore, based on the designers and contractors´ comments, 24 constructability barriers were obtained. The most relevant barriers in the local context were the lack of a culture of design and planning in the undertaking of construction projects and the great informality with which building projects are developed.
