Proposed supplier assessment tool: a contribution, according to the conformity assessment system (SIAC)/PBQP-H

Abstract

An important contribution of the Brazilian standard NBR 15575 (ABNT, 2021) is the proof of construction performance, namely: its materials, services and systems employed. This article deals with the proposal and validation of a tool, created in Microsoft Office Excel, to demonstrate the proof of performance regarding the responsibility of suppliers of materials/inputs, systems, services and designers. For this purpose, the “Supplier Assessment Tool (FAF)” was proposed, validated and applied in the construction system of concrete walls cast in situ, of a multifamily building with 496 units in the city of Goiânia/GO/Brazil. Thus, the technological control plan and the performance profile of the building, provided by the construction company, were observed. After that, indicators were attributed regarding the items of receipt or not of documentation proving performance and when this was done (whether at the time of contracting, execution, delivery or if it was not delivered), covering stages from implementation to completion of construction. As a result, the tool proved to be effective in controlling the proof of performance documents of the construction company. The diagnosis was that 57% of the suppliers evaluated did not meet the proof of performance, 11% met the requirements late and 38% met the requirements well. Finally, this allowed for the identification of supplier limitations, failures in the acquisition of materials/services, and improvements in the management system and the construction company's purchasing flow. The AAF can be applied to other construction projects of the company.
