Abstract

Selecting a Takt Planning strategy for basement construction with precast slabs is a production system design problem, since different combinations of sectorization and takt time lead to different tradeoffs in duration, variable cost, and implementation demands. Existing Takt Planning research provides limited support for systematically generating comparable alternatives and justifying strategy selection for a specific project context. This paper proposes a framework to generate, compare, and select Takt Planning strategies and applies it to six basement levels of a multifamily building in Lima, Peru. The alternatives are defined by combining sectorization and takt time and are assessed through project duration, variable cost, and implementation demands related to structural capacity, supervision, material logistics, labor, and cash flow. Results show that shorter duration alone is not a sufficient basis for selection, because alternatives with similar time and cost performance can impose substantially different implementation demands. In the case studied, the alternative with five sectors and a one day takt provided the best balance between economic performance and implementation feasibility. The paper contributes a structured procedure to support early Takt Planning decisions under real project constraints. Future research should test the framework in other project types and refine the assessment of implementation demands.

Keywords
