Process systems we build for pharmaceutical manufacturing
Pharmaceutical production runs on tightly controlled utilities and product-contact surfaces. Water for formulation and cleaning must meet compendial grades; steam that sterilizes must be clean; every wetted surface must be smooth, drainable, and documented. Paul Industries builds the full stack of these systems as one contractor, which keeps design intent, weld quality, and validation records aligned instead of scattered across trades. Our core scope covers high-purity water generation and distribution (USP Purified Water and Water for Injection), Clean-in-Place and Steam-in-Place skids, cleanroom envelopes classified to ISO 14644, sanitary process piping fabricated to ASME BPE, and the installation of bioreactors, mixing and formulation tanks, and autoclaves. Because a pharmaceutical system is only accepted once it is proven, we carry the work through commissioning and qualification — IQ, OQ, and PQ — with the turnover documentation an FDA-regulated site needs.
The regulatory driver behind all of it is current Good Manufacturing Practice. Under 21 CFR Parts 210 and 211, equipment must be of appropriate design, adequate size, and suitably located for cleaning and maintenance, and water used in production must meet defined quality attributes. That is why material selection (typically 316L stainless), surface finish, slope-to-drain, and orbital welding are not cosmetic choices on a pharma job — they are compliance requirements that get inspected, tested, and recorded.
Common pharma systems and the standard each requires
| System | Governing standard | Water grade / classification |
|---|---|---|
| Purified Water (PW) generation & loop | USP <1231>, ASME BPE, cGMP | USP Purified Water |
| Water for Injection (WFI) system | USP <1231>, ASME BPE, cGMP | USP WFI (highest purity) |
| CIP / SIP skids | ASME BPE, cGMP | PW/WFI + clean/pure steam |
| Sanitary process piping | ASME BPE (SF finish, slope-to-drain) | Product-contact 316L |
| Cleanroom / fill-finish suite | ISO 14644-1, cGMP | ISO Class 5–8 air |
| Bioreactor & tank install | ASME BPE, cGMP | PW/WFI feeds |
| Autoclave / sterilizer | cGMP, validation | Pure/clean steam |
What we build
- High-purity water systems — USP Purified Water and WFI generation, storage, and distribution loops built and passivated to hold compendial quality.
- CIP/SIP systems — Clean-in-Place and Steam-in-Place skids and circuits that clean and sterilize product-contact equipment repeatably and on record.
- Cleanrooms — ISO 14644-classified envelopes, airlocks, and fill-finish suites with the finishes and controls a sterile process demands.
- Sanitary process piping — ASME BPE 316L piping, orbital-welded, sloped to drain, with documented weld maps and finish.
- Validation & commissioning — IQ/OQ/PQ execution, passivation and riboflavin coverage testing, and full turnover documentation.
- Bioreactor, tank & autoclave installation — setting, tie-in, and qualification of mixing tanks, bioreactors, and sterilizers into the utility network.
Standards & compliance
- cGMP — 21 CFR Parts 210 & 211
- The FDA regulations that govern drug manufacturing. They require equipment to be designed, sized, and located so it can be cleaned and maintained, and require water and utilities to meet defined quality — the baseline every system we build must satisfy.
- USP <1231> — Water for Pharmaceutical Purposes
- The compendial chapter defining how PW and WFI systems are designed, monitored, and maintained. It shapes loop velocity, dead-leg limits, sanitization, and sampling on the water systems we install.
- ASME BPE — Bioprocessing Equipment
- The standard for hygienic design of product-contact systems: surface finish, orbital welding, slope-to-drain, and material traceability. It governs how our sanitary piping and skids are fabricated and inspected.
- ISO 14644 — Cleanroom classification
- Defines air-cleanliness classes (Class 5–8 in typical pharma use) by particle count. It sets the performance target our cleanroom envelopes and HVAC integration are built and tested to meet.
- IQ / OQ / PQ — Qualification
- Installation, Operational, and Performance Qualification — the documented proof that a system was installed correctly, operates within spec, and performs reliably under load. We execute and document each stage at turnover.
- 21 CFR Part 11 — Data integrity
- Governs electronic records and signatures for regulated data. Where our systems tie into monitoring or automation, controls and records are handled so validation and audit trails hold up to inspection.
Why Paul Industries
Pharmaceutical projects fail at the seams — between the water skid vendor, the pipe fitter, the cleanroom installer, and the validation group. Paul Industries removes those seams by carrying design, fabrication, installation, and validation under one accountable team, so weld quality, slope, and qualification documentation trace back to a single source. Thirty-plus years of cGMP/FDA-compliant work means we build for the inspection, not just the startup: material certs, weld logs, passivation records, and IQ/OQ/PQ packages come with the system. We respond nationwide for new builds, retrofits, and shutdown work — and we stay on for the preventive maintenance that keeps a validated system in a validated state.

Services we provide for pharmaceutical manufacturers
Pharmaceutical facility construction and fit-out is where most of our services meet on one site, under 21 CFR 210 and 211. For a pharmaceutical plant we provide: sanitary process piping and pharmaceutical process piping to ASME BPE, with orbital welding and sanitary welding documented for installation qualification; purified water and WFI systems, RO skids and clean steam generators and distribution; pharmaceutical cleanroom construction from Grade D support space to the Grade B background of an aseptic core, with the cleanroom contractor scope carried in full; CIP and SIP systems and CIP skids; process tanks, buffer preparation systems and liquid process systems; passivation and derouging of installed systems; autoclave installation; installation of pharmaceutical process equipment supplied by the owner or OEM, with millwright and rigging; commissioning and qualification support; and FDA 483 water system remediation when an inspection has already happened. Turnkey process systems bring these under one contract.
The requirement set a US drug plant inherits before it can ship
| Requirement | What applies to a pharmaceutical process system |
|---|---|
| Governing regulation and clause | 21 CFR 211. Section 211.65 calls for equipment surfaces that are not reactive, additive or absorptive; 211.67 governs cleaning and maintenance; 211.48 governs plumbing and the potable feed. EU GMP Annex 1 sits on top for any sterile operation. |
| Typical water grade | USP Purified Water for formulation, granulation and final rinse, held to the conductivity and TOC limits of USP <645> and <643>. USP Water for Injection where the product is parenteral, which adds a bacterial endotoxin limit of 0.25 EU/mL. |
| Typical cleanroom class | ISO 14644-1 Class 8 for gowning and material transfer, Class 7 for compounding and solid dosage support, Class 5 wherever product is open to the room. Annex 1 Grades A through D map onto those classes on sterile lines. |
| Typical documentation package | User requirement specification, design qualification, factory and site acceptance testing, then IQ, OQ and PQ. Turnover adds the weld log with borescope records, mill test reports traceable to heat number, the passivation certificate, calibration certificates and as-built isometrics. |
| Typical materials and surface finish | 316L on every product-contact surface, fabricated to ASME BPE. SF1, mechanically polished to 20 Ra micro-inch maximum, covers most purified water and process lines. SF4, electropolished to 15 Ra micro-inch maximum, is specified for WFI distribution and where a bioburden argument has to be made. |
Those five lines decide most of a bid. The clause engineers underestimate is 211.65, because it is not a finish specification, it is a behaviour specification: the surface must not add to, react with or absorb the product. A weld carrying heat tint, a crevice at a badly fitted gasket, or a dead leg that holds rinse water all fail that test whatever the Ra number on the tube certificate says. Water grade then sets sanitization temperature, which sets material selection and slope. Documentation is the line cut first in a tight bid and the most expensive one to recover later, because a weld you cannot evidence is a weld an investigator treats as unverified.
Membrane WFI vs multiple-effect distillation on a new loop
Water for Injection no longer has to come from a still. The USP monograph allows a purification procedure equivalent or superior to distillation for removing chemicals and microorganisms, which brought reverse osmosis and ultrafiltration trains into scope. The choice is an engineering decision now, not a compliance one.
A still earns endotoxin and microbial control through phase change. That mechanism is robust, straightforward to defend in an inspection, and it arrives with a steam load, a cooling load and real mechanical maintenance. A membrane train earns the same result by design: multiple barriers, continuous recirculation, hot or ozonated sanitization, and instrumentation that proves the barriers held. Capital and energy run lower. Validation scrutiny runs higher, because the argument rests on the system rather than on physics.
The deciding question is rarely price. It is what happens on a bad day. A still that drifts makes water that fails a test. A membrane train that fouls can keep passing conductivity and TOC while microbial control degrades quietly. Both routes carry published bands on the high-purity water cost guide.
What to verify before awarding a cGMP mechanical package
Two bids on the same drawing set can differ by a factor of two, because the scope behind the number differs. Require written answers before award.
- Welding procedure and operator qualifications to ASME Section IX, with coupon and borescope frequency stated as a count per shift rather than “as specified”.
- The ASME BPE surface finish designation quoted line by line, and the instrument that will verify it on site.
- Whether passivation is in scope, to which ASTM A967 practice, and which acceptance test gets run and recorded.
- Who writes the IQ and OQ protocols, who executes them, and whether the PQ sampling program is priced or excluded.
- Slope shown on the isometrics for every line, with the method for demonstrating drainability at turnover.
- Material traceability by heat number for tube, fittings and valve bodies, not a blanket certificate of conformance.
- Named exclusions answered one at a time: insulation, supports, instrument calibration, cleaning chemicals, start-up utilities.
A bidder who will not put these on paper before award will not produce them after it. We self-perform design, fabrication, welding, passivation and qualification support, so the answers come from one contract. Start at the quote page or call 201-450-8280.
Published ranges a pharmaceutical project can plan against
Figures already published on this site. Budget bands, not a quotation.
- Fit-out by area type, from the turnkey GMP facility cost page: unclassified support and warehouse $90 to $190 per sq ft, controlled not classified $120 to $240, ISO 8 $150 to $365, ISO 7 $240 to $540, ISO 5 aseptic fill suite $700 to $1,650.
- Clean utilities on that same page: USP Purified Water at 10 gpm $300,000 to $800,000, Water for Injection at 100 gph $660,000 to $1,800,000, a clean steam generator $135,000 to $620,000, and distribution loop at $255 to $630 per linear ft.
- Its worked 20,000 sq ft sterile fit-out lands at $21 to $43 million, excluding land and base building.
The loop figure surprises owners most. Distribution routinely costs more than the generation skid feeding it: every use point adds a valve, a drop, a slope requirement and a sampling location.

What is clean steam and why do pharma facilities need it?
How long does a pharmaceutical water system project take?
Typically nine to eighteen months from order to a validated system, and the shape surprises people. Generation equipment lead time commonly runs six to nine months and sets the front. Loop installation is six to sixteen weeks. Then qualification adds a fixed tail that no amount of labor compresses: two to four weeks of daily sampling at every point for phase one, a similar span for phase two, and a full year of routine monitoring for phase three, with production normally permitted after phase two.
What does IQ/OQ/PQ mean for a pharmaceutical utility?
Can Paul Industries retrofit or expand an existing pharma facility?
What causes a pharmaceutical water system to fail USP limits?
Does Paul Industries serve pharmaceutical companies nationwide?
Yes, across all 50 states, as planned programs with dates confirmed at quotation rather than as local availability. On pharmaceutical water work that is seldom the binding constraint, since equipment lead time governs the start and laboratory incubation governs the finish. What we ask for early is the feed water analysis and demand profile, because those determine the design and are expensive to revisit once equipment is ordered.
What is passivation and why is it required for pharma stainless systems?
How do we start a pharmaceutical process-system project?
What process systems do pharmaceutical plants need?
Do you build to cGMP and validate (IQ/OQ/PQ)?
What water grades do you install (PW vs WFI)?
Which states do you serve?
Every state, from one base in Kilmarnock, Virginia. For pharmaceutical clients the more useful question is usually consistency across sites rather than coverage of any one: where each plant engages a different contractor, weld documentation formats, passivation certificate scopes and qualification protocols diverge, and a corporate quality group reconciles them during an inspection. One procedure and one record format across sites removes that.

Request a Project Quote or call 201-450-8280Can you handle a facility retrofit without stopping production?
Usually yes, and for pharmaceutical facilities specifically the constraint is rarely the mechanical work. Phasing around production, sectional isolation and pre-fabricating spools off site all compress the outage. What determines whether production genuinely continues is the requalification that follows, because a change to a qualified system is assessed by risk rather than by how much pipe was touched, and a small tie-in on a compendial loop can require sampling across the whole loop before it releases water again. The workable approach is to install isolation and capped connections during an earlier planned shutdown so the eventual tie-in is made on a system already prepared for it.
How is a multi-product facility designed to prevent cross-contamination?
Through segregation of air handling and pressure cascade, dedicated or validated-cleanable equipment, material and personnel flow that does not cross, and cleaning validation with residue limits derived from toxicological data. The design decision is made before the layout is fixed, not after.
What is a health-based exposure limit and why does it affect design?
It is a toxicologically derived limit for how much of one product can carry over into another, and it sets the cleaning acceptance criterion. Where that limit is very low, the facility design may have to move from cleaning validation to dedicated equipment or containment.
What does ASTM E2500 change about commissioning and qualification?
It reframes the work around verifying what matters to product quality and patient safety, using risk assessment and supplier documentation rather than duplicating testing. It does not remove the evidence requirement. It concentrates it on the critical aspects.
How is a pharmaceutical facility expanded without disturbing the validated state?
By isolating the work behind a documented boundary, assessing the impact on adjoining validated systems under change control, and requalifying only what the assessment shows was affected. The isolation boundary and the impact assessment are the two documents that decide how large the requalification becomes.
