Throughout the history man has strived to achieve the most conformable environment, with the use of technology available at the time. This endeavor led to the development and subsequent innovations in different fields concerned with the buildings. Today various aspects of building technologies, structural- electrical-mechanical-air-conditioning, etc., have attained highly developed form and involves specialized services from technically qualified and experienced personnel.

Although the various aspects need highly specialized services independently, it is also true that at no stage during the process of design and execution, these various services, can be treated independently. The continuous feed backs make extremely important to have very close co-ordination amongst them.

It is, in order to cope with this state of technological development, that the group SEM has been formed to provide technical services covering all the disciplines associated with the building industry within one organization. This group consists of qualified, experienced and highly capable dedicated engineers having vast knowledge of developments, throughout the world.
