DIVISION 04 · UTILITIES · BUNDLED OR STANDALONE
Utility Tie-Ins and Process Piping
The equipment is set. Nothing is connected to it. This is that scope.
Infrastructure for utilities and tie-ins is available for any Miller 3 Engineering service, and standalone utility runs and connections are available on their own.
Utilities are the scope everyone assumes somebody else has
Read a typical equipment purchase order. It ends at the machine. Read the installation quote from a labor-only contractor. It ends at "set and anchor." Read the electrical proposal. It starts at the disconnect.
Between those three documents is a gap that contains: the compressed air drop, the process water line, the drain and the trap primer, the exhaust duct and where it goes through the roof, the containment curb under the chemical skid, and the twelve feet of stainless that connects the new filler to the old surge tank.
The full detail
Agitate: That gap gets discovered on install week. Which means it gets priced on install week, by whoever happens to be standing there, at whatever rate they feel like. It is the single most common source of change orders on equipment projects, and it is almost always avoidable, because the drawings existed months earlier and nobody read them as a connection list.
Worse, half of that scope is regulated. Secondary containment around a chemical process is not a nice-to-have. A trap on a food drain is not optional. Getting it done fast by whoever is available is how a plant fails an inspection six months later.
Solution: We scope the connections at the same time we scope the equipment, and we self-perform the mechanical and plumbing side. One contractor holds both ends of every connection.
Plumbing scope
| Service | What it covers |
|---|---|
| Process utility piping systems | Product, CIP, water, steam, glycol, compressed air, gas, and chemical lines |
| Industrial plumbing services | Drains, floor sinks, trap primers, water services, hose stations, eyewash and safety showers |
| Secondary containment | Containment curbs, sumps, lined pits, and spill control around process equipment |
Mechanical scope
| Service | What it covers |
|---|---|
| Air and environmental systems | Dust collection, ductwork, exhaust, make-up air, fans, filtration, ventilation |
| Process utility systems | Compressed air distribution, vacuum, process cooling, and utility skids |
| Material handling systems | Conveyance and transfer connections between equipment |
| Process equipment integration | Tying new equipment into existing process lines and existing controls |
| Containment and safety systems | Guarding, interlocked access, spill and fume containment, safety devices |
How we run a tie-in
Connection list before drawing list
Every utility the equipment needs, where the nearest available source is, what capacity it has left, and what has to change.
Field verify the source
The panel schedule says there is a spare. The air header says 100 psi. Both are frequently wrong. We check.
Route and support
Pipe routing that stays out of maintenance access and forklift paths, with real hangers and supports, fabricated by the same shop doing the structural steel.
Prefabricate spools
Shop-fabricated pipe spools cut the on-site window, which matters when the connection is inside a shutdown.
Tie in during the window
The hot cut is scheduled, not improvised.
Test, document, and close out
Pressure test, function check, and punch-list closeout alongside the equipment commissioning.
Standalone work
Stand-alone utility runs and connection services are available.
You do not need an equipment project to hire us for this. Common standalone calls: extending a compressed air header into a new production area, adding secondary containment to bring a chemical storage area into compliance, replacing a failed dust collection duct run, and adding a drain and containment to a wash bay.

Common questions
Do you do electrical work?
We coordinate electrical rather than self-perform the full scope. Electrical coordination is a standard part of our installation and campus utility integration work, and on the OEM case study the scope included coordination of utilities including electrical, air, and process services. Terminations and controls are typically handled by a licensed electrical contractor or your integrator, working to our sequence.
Are you licensed for plumbing and process piping?
Miller 3 Engineering holds California contractor license #1136711, and you can verify the classifications it covers at cslb.ca.gov.
Can you weld stainless and sanitary process piping?
Sanitary construction is a defined capability across our food and beverage work, including sanitary equipment for washdown environments, corrosion-resistant materials, and smooth surfaces with minimal debris traps.
Will you work off our drawings or produce your own?
Either. If you have a P&ID and a piping plan, we build to it and flag what we think will not work before we cut. If you have a machine and a wall, we produce the routing drawings. We have engineers on staff who design, draft, and stamp, and pull permits when a project requires it.
Can you do the tie-ins during a plant shutdown?
That is the normal way this work happens. Tight sequencing to meet shutdown windows and deadlines is part of how we execute. Prefabricating pipe spools, supports, and duct sections in the shop is what makes a 12-hour window realistic instead of optimistic.
Do you handle secondary containment for chemical storage?
Yes. Secondary containment is a defined part of our plumbing scope, and containment and safety systems are part of our mechanical scope. Common work: containment curbs and coated sumps under process skids, lined containment for tote and drum storage, and sloped drainage with spill control. See chemical processing for the industry context.
