an autonomous variable. The second cluster consisted of the
dependent variables that had weak driver power but strong
dependence. Safety culture, continual improvement, morale of
employees, and safety training were identified as dependent variables.
The third cluster had the linkage variables that had strong
driver power and dependence. Safety performance, sustainable
construction and conducive working environment were identified
as linkage variables. The fourth cluster included the independent
variables that had strong driving power but weak dependence.
Management commitment and safety policy were identified as the
driver variables.
To better understand the factors influencing implementation of
OHSAS 18001 in Indian construction organizations, we used an ISM
approach. We identified nine factors crucial for implementation of
OHSAS 18001 and the relationships among them. The results of the
study serve as a guideline for top management to concentrate on
influential factors and it can assure the successful implementation
of OHSAS 18001 in construction organizations. In this case, management
commitment and safety policy fall in the category of independent
(driver) factors. It is obvious that management
