Planejamento de escopo, tempo e custo com avaliação de viabilidade econômico-financeira para a construção de um chalé turístico

Abstract

This work presents the detailed planning of scope, time, and cost for the construction of an 80 m² A-frame tourist chalet, located in the interior of São Paulo. The relevance of the topic is justified by the strong development of the region as a viticultural hub and by the growth of wine tourism, which drives the demand for differentiated accommodations. The study was motivated by the opportunity to apply Production Engineering tools to technically structure the enterprise and ensure its viability. Characterized as applied research with a quantitative methodological approach, the work is configured as a single case study with a descriptive objective. The methodology consisted of developing a Work Breakdown Structure (WBS) for scope delimitation, followed by the application of the PERT Method and identification of the Critical Path for temporal planning, in addition to the preparation of a detailed budget with ABC Curve and S-Curve analyses. The results demonstrate that the project requires a total investment of R$ 345,622.61 and presents a total duration of 258 days, a schedule that covers the full project lifecycle, from feasibility studies and land acquisition to the final delivery of the work. Within this period, the specific stage of civil construction execution comprises a total of 62 days. The ABC Curve analysis revealed that only five out of fourteen items concentrate about 80% of the costs. Economic viability was validated by indicators such as Discounted Payback and Net Present Value (NPV), showing that the integration of these tools increases project predictability and reliability. The Discounted Payback obtained was 2.77 years, while the NPV presented a positive result of R$ 57,580.27, indicating economic value generation for the project. Thus concluding that structured planning is fundamental to the success of capital projects, serving as a replicable methodological model for the tourism sector.
