ABSTRACT
The present work focuses on the analysis of data from two actual construction works, and the case study is made on the data of the Work of “Modernization of Secondary School Camilo Castelo Branco-CCB” in Barcelos for the beginning of the time period July 2009 to end-September 2010, corresponding to the total of the Work. It was considered the data from the first nineteen months of the Work of the General Construction Contract, ie, beginning in April 2010 until the end of November 2011 the Work of “Strengthening Power of Venda Nova-Venda Nova III” in Ruivães, municipality of Vieira do Minho, which will be finalized in mid 2015. To identify the investment in prevention of the safety at work, were collected the data for safety costs in the two works under review, involving human and material resources, which allow us to conclude the sum, a percentage of the total cost spent on safety at work against the total cost of the contract, designated Safety Costs (SC). The identification of the Anomalies Cost Correction (ACC), was done by the method of Probabilities and Consequences adapted to Case Studies, to examine all the anomalies of Registers of Inspection Visits (where are described anomalies found at the time in the Work, which were sent to the Contracting Performer for knowledge), Registries Non conformance and registers of accidents and incidents. The procedure was for the suggestion, more economic, of correction of deficiencies found and anomalies that caused accidents and incidents. The total economic cost of these suggestions for improvement will be the Anomalies Cost Correction (ACC). The Safety Costs (SC) added to the Anomalies Costs Correction (ACC) will be the Cost Desired Safety (CDS). CDS = SC + ACC. Thus, Cost Desired Safety (CDS) will be the investment necessary for the Work to be considered Safe. The Costs of “No” Safety at Work (CNS), will be the sum of the Direct Costs (DC), ie, reimbursable by insurance and Indirect Costs A (IC), ie, not reimbursable by insurance. A methodology was followed according Reis (1998). If the Anomalies Costs Correction (ACC) is less than the costs of “No” Safety (CNS), we reach the conclusion it pays to invest in safety against the risk of potential costs of “No” Safety (CNS). Once the accidents have significant impacts on workers, organizations, and society in general, it was intended with the elaboration of this study, to quantify the economic cost they represent of the Building Sector. It was intended to still demonstrate that the lack of investment of safety at work potentiates work accidents and incidents/near accidents and thus pays to invest in the Safety at Work in Building, because the costs of “no” safety can be potentially higher than the costs of safety.
