Our history


ACEDA was founded in the year 1977. All Ceylon Engineering Diplomates Association for the general advancement of the Technology and practice of Engineering advancement of Technology and practice of Engineering in all its branches was a brain child of few Diplomates and it look after interests of the Engineering Diplomates in Sri Lanka. The Association grew from strength to strength establishing due recognition for Engineering Diplomates assisting in upgrading the professional status of the members and working towards winning all due rights.


The ACEDA wasthen  transformed into the Institute of Engineering Diplomates. In 1992 it was transformed to a professional body under the name of  “Institute of Engineering Diplomates, Sri Lanka by an Act of Parliament No 64 of 1992. The Institute was opened to all Engineering Diplomates. It has various classes of membership and therefore allowed anyone interested in the field of Technology to further their interest and their carrier.


In year 2000  in keeping with the international standards of professional engineering societies of similar nature,IEDSL was renamed with the present status as “Institution of Incorporated Engineers, Sri Lanka” by an Act of Parliament (Act No 11 of 200). IIESL has a wide opening for personnel of all levels in the field of Technology, gaining due recognition for the members locally and internationally as well. Incorporated Engineers are the internationally recognized category of Engineers in the field of Technology, who effectively manage the construction, operation, maintenance and project management functions, by implementing appropriate technology.

At present following eleven fields of Engineering Technology are represented by IIESL

Civil Engineering Technology, Chemical and Process Engineering Technology, Electrical Engineering Technology, Electronic & Telecommunication Engineering Technology, Marine Engineering Technology, Mechanical Engineering Technology, Nautical Studies & Technology, Polymer Technology, Textile & Clothing  Technology, Information Technology, Agriculture Engineering Technology

During past 37 years the Institution gained a rapid progress and the success of this achievement is due to the team work, and also the commitment, sacrifice and hard work of all Past Presidents, Council Members and the general membership.

We, as the professional body of Incorporated Engineers, who are managing & operating Engineering Technology in the country, have the mandate to develop professionalism among the members. During the present time of rapid economic & global changes, we find ourselves challenged very often to maintain our professional integrity and standards of conduct in professional activities and business activities.

The main objectives of IIESL are to meet the needs of Incorporated Engineers to develop their skills and knowledge by contributing professional development; set standards of education  and engineering proficiency and maintain them by continuing association with educational process; co-ordinate all related activities on national relevance; international recognition; innovation; creativity  and quality education and training of Engineering Technology; find strategy to influence government policy for sustenance technological, social and economic  development of the country; some public invest in creating   wealth, health, safety and environment at high quality. Any profession whilst perusing these arms cannot isolate itself from society at large or the ultimate welfare of the community from which all of us obtain sustenance, and within boundaries of which we have to live.  Today it is necessary for each individual and each organisation to contribute seriously to the general welfare of own well-being. Since education, knowledge, competence, attitude, ability to practice ones profession and ones place in society, all become concern of the Institution.
