Here's how the work actually runs on our St. Louis jobsites. Crews rotate between ground-up construction, [tenant finish plumbing](https://legacyplumbingmo.com/commercial/tenant-finish) inside occupied buildings, and service work such as [grease trap cleaning and pumping](https://legacyplumbingmo.com/facility-services/grease-trap-cleaning) for restaurants and food-service kitchens. ### Pre-job planning, in writing Before a crew mobilizes, the job gets a written plan — scope, sequence, material staging, and who owns what. You show up knowing the day's work instead of guessing at the gang box. ### Trained foremen, real supervision Foremen here go through leadership and layout training before they run a crew. Nobody gets handed six guys and a prayer. If you're stuck, there's someone on site who can actually answer. ### Tools and material that show up Specialty tools, press gear, jetters, locators, and cameras are company-provided and maintained. Material gets ordered off the plan, not off a panic phone call at 9am. ### A path you can see Apprentice to journeyman to foreman to superintendent or estimator. Each step has a written expectation list, so you know what you're being measured on before the conversation happens. ### Modern estimating and scheduling Jobs are bid and scheduled with current software and field-verified layout — including total station layout on larger projects — so field work gets set up to succeed instead of chased. ### Small enough to know your name You'll talk to the people who run the company, not a call center. Feedback from the field actually changes how the next job gets built.
