Contractors, if you are engaged in the business of installing or retrofitting electrical, plumbing or mechanical systems in government or commercial buildings, we can help you bring your project in on time and on budget. We will core drill your existing concrete walls and floors, precast hollow core planks, sewer manholes, and asphalt pavement for installation of electrical and mechanical works. Airport light bases and transformer housings drilled in existing pavement to retrofit lighting. Light bases and transformer housings can be overdrilled after finished asphalt pavement is in place. Deep holes and large diameter holes can be drilled with our electric or hydraulic rigs. We are experienced in airport, metro, and federal government operations.
