The Meralco Industrial Engineering Services Corporation story

Incorporated in 1973, Meralco Industrial Engineering Services Corporation (MIESCOR), a solely-owned subsidiary of Meralco, has been the driving force behind every construction and engineering project of its parent company. The corporation has two wholly-owned subsidiaries: MIESCOR Logistics, Inc., an electronic manufacturing company, and MIESCOR Builders, Inc., a licensed category AAA contractor with specialties in building, mechanical, civil, and general engineering works. 

For around four decades, MIESCOR has built most of the country's energy and power businesses, as well as the support system that drives them. Today, the company has over 5,000 project management professionals, specialist engineers, and workers. The corporation has been recognized by safety regulating bodies and a number of associations including the Safety Organization of the Philippines, Inc. and the Department of Labor and Employment for its health, security, and environmental efforts. 

MIESCOR's quality management system has achieved ISO 9001:2015 certification for its processes in engineering, procurement, and construction services as awarded by TUV Rheinland, a certifying body. The ISO 9001:2015 standard is a set of practices and quality parameters that oversees the use of effective processes that are consistently monitored and improved. 

Today, the MIESCOR Group is highly involved in a variety of projects for MERALCO, Smart, Maynilad, and PLDT, among others in the energy and utility industry.


Low salary is a common issue. Some employees report fringe benefits that include health insurance and loans, in addition to government-mandated benefits. 


The supervisors are described by staff as efficient and approachable. The work environment is often described as fun and friendly. 

Social contributions

Meralco seeks to serve society through its corporate foundation and social development arm, the One Meralco Foundation (OMF). The foundation rallies Meralco employees, business and government partners, and its subsidiaries and affiliates to engage in sustainable and long-term programs that focus on grassroots partnerships, youth and sports advocacy, energy education, community electrification, and employee volunteerism.

OMF, once named Meralco Millenium Foundation, was re-launched in 2011 with core advocacies aligned to the corporate goals of its parent company. The foundation has been consistently recognised by various award-giving bodies that include the Global CSR Award, Philippine Quill Awards, Anvil Awards, PR News Online's CSR Awards, Corporate Governance Asia Awards, and FinanceAsia, among others.
