In 1966 the Associated Construction Equipment Lessors, Inc. (ACEL) was incorporated to provide some solutions to the problems that beset the construction industry at that time. ACEL introduced the system of equipment leasing which is accepted as the best possible alternative to acquiring heavy equipment for immediate use, where outright purchase may not be possible because of the huge capital outlay involved.

As part of its continuing program for the development and upgrading of competency of the nation's manpower resources, the Association of Carriers and Equipment Lessors, Inc. and the Technical Education and Skills Development Authority (TESDA) have signed the Memorandum of Agreement (MOA) that would give ACEL the sole responsibility of implementing a nationwide and unified system of occupational skills assessment and certification in the heavy equipment subsector of the construction industry.
