Implementing Takt Production in Renovation Projects

Abstract

Renovation projects are a special type of construction projects. The unique features of renovation projects make production control challenging, as they often cause a great deal of variation, resulting in waste in production and reducing profitability. Takt production has been applied to renovation, but its specific suitability and benefits in renovation projects have not been studied widely.This paper describes a design science study that i) examines the suitability of takt production in renovation projects through literature and interviews, ii) designs a process model for applying takt production in renovation projects, and iii) applies and validates the designed process model in a case project.The findings imply that takt production can benefit renovation projects. The study highlights the significance of fulfilled prerequisites and well-managed supporting functions in takt production. If these requirements are not fully met, the significance of proactive problem-solving in production control and collaborative practices increases.

Indicators for Takt Production Performance Assessment—A Conceptual Study

“…Sahlberg et al [18] described a case takt production construction project, writing that "the implementation was found to be mostly successful", with schedule-related challenges with building services systems. Lehtovaara et al [16] mentioned that "Despite the significant planning effort, during the control phase it was realized in every case that it was not possible (or even a goal) to precisely follow the initial plan" and that "the amount of making-do was perceived to be large in almost all cases, which also caused production to slide towards traditional [non-takt production] ways of working".…”

“…What is barely addressed is (a) has it been the intention to punctually adhere to the takt plan, and (b) has the execution been successful. (2) There have been challenges related to takt planning and control [16,18]. Therefore, methods should be developed to analyze and visualize production data for production steering.…”
