For developers, general contractors, and property managers working on large-scale projects in the rapidly evolving Los Angeles landscape, the plumbing infrastructure represents a critical foundation for success. It demands more than just standard service; it requires the expertise of a specialty contractor who can integrate complex mechanical and utility systems into ambitious new construction and redevelopment projects. GJM Engineering Inc is recognized as a premier plumbing specialist in the greater Los Angeles area, dedicated to tackling the demanding and technical requirements of modern commercial and multi-unit residential construction in California.

Founded by contractor and businessman Greg Missick, GJM Engineering Inc has been deeply involved in the changes and innovations defining the city of Los Angeles for over 30 years. The company is structured as a construction engineering firm, successfully blending deep plumbing expertise with broad mechanical and general contracting knowledge. This combination allows GJM to offer turnkey solutions for projects that range from high-rise apartment buildings to essential public infrastructure, consistently partnering with private developers and government agencies to build the commercial backbone of California’s 21st century.

Unlike small-scale residential plumbers, GJM Engineering Inc operates at a commercial and institutional level, where the stakes are higher and the systems are exponentially more complex. Their work is often foundational, involving underground service, large-scale pipe line installation, and intricate gas systems necessary for the function of major commercial facilities.

In a metropolitan area like Los Angeles, where population density and constant development strain existing utilities, the role of an expert site utility contractor is indispensable. GJM Engineering Inc’s capacity to manage site utility work, including sewer contractor responsibilities and complex subterranean installations, ensures that new facilities are seamlessly integrated with municipal services, meeting all local regulations and engineering standards. This specialized focus on commercial and infrastructure needs provides a vital service to the growth and sustainable development of the California region.

Their involvement as the Plumbing Contractor for major apartment complexes, such as the Broadway Palace Apartments and Medici Apartments in Los Angeles, highlights their proficiency in handling the vast and complex plumbing networks required for high-density, multi-story buildings.
