Londonderry is a major southern New Hampshire logistics and tech market near Manchester-Boston Regional Airport, with distribution facilities, tech manufacturing, and commercial development driving engineering demand.

What we design

Plumbing engineering for Londonderry data centers & server facilities is riser diagrams, fixture-unit math, and gas sizing done right the first time. Torch designs domestic water, sanitary, storm, and gas systems to the New Hampshire plumbing code, details freeze protection for cold, snowy winters, and seals every isometric with a licensed PE.

  • Gas load calculations and piping layouts for Londonderry corporate technology campuses — rooftop units, water heaters, and kitchen equipment all on one coordinated schedule the gas utility and the Londonderry building department both accept.
  • Domestic water and sanitary design for Londonderry data centers & server facilities: pipe sizing by fixture-unit method, pressure-booster evaluation where city pressure falls short, and backflow assemblies located per the Londonderry building department requirements.
  • Fixture counts per the New Hampshire plumbing code for Londonderry data centers & server facilities: water closets, lavatories, and drinking fountains calculated by occupancy, with ADA clearances drawn — not assumed.
  • Londonderry corporate technology campuses with process loads get engineered details, not catalog cuts — interceptors, separators, and specialty drainage drawn to the New Hampshire plumbing code.
  • the Londonderry building department plumbing review in Londonderry, NH keys on isometrics, fixture-unit math, and gas sizing — our Londonderry sets include all three, drawn cleanly enough that corrections stay minor.
