Determination of the elimination costs of vibrations and dust transmission in refurbishment healthcare buildings works in Spain

The aim of this paper is to evaluate the average cost of preventive measures for noise insulation, vibrations and dust transmission in healthcare buildings, which guarantee environmental biosafety in renovation infrastructure works. 30 hospital reformation works carried out between 2004 and 2010 in Spain were analyzed. The average impact of the environmental biosafety measures incorporated in the project was 1.07 % of the budget. The average cost of the actions was 5.5 €/m2 in works in critical areas and 0.9 €/m2 in the rest. In critical areas, the sectoring meant an average cost of 26.89 % of the budget of the work and in the rest of areas of 29.48 %. It was concluded that the management of environmental biosafety in the works means a minimum cost, which reduces the transmission of noise, vibrations and dust, reducing the probability of nosocomial infection.
