About the Firm

Built on Three Decades
of Field-Proven Expertise

Quantaris Integrated Services LLC is a Houston-based independent engineering consultancy serving a broad range of process and industrial sectors — from chemical manufacturing and petrochemical plants to water treatment, pulp & paper, and green energy facilities. Founded by a control systems engineer with over 30 years of hands-on project delivery across diverse industrial environments.

We exist to give plant operators, facility owners, and EPC firms access to senior-level technical judgment without the overhead of a large firm. Every engagement is led by a principal engineer, not delegated to juniors. Every recommendation is vendor-neutral and grounded in real-world operating experience.

"The right answer isn't the most sophisticated one — it's the one that works reliably at 3 a.m. in a remote facility."

Project Experience

Industrial automation projects across chemical plants, petrochemical facilities, water treatment plants, power generation, manufacturing, and process industries worldwide.

Recognized Expertise

Deep domain knowledge in DCS, SCADA, PLC, SIS, industrial networks, field instrumentation, hazardous area classification, and intrinsically safe system design.

Standards & Compliance

Hands-on experience with IEC 61511, IEC 61508, ISA 84, NEC/NFPA 70, ISA/IEC 60079 (Ex standards), API/ISO standards, and corporate automation design guidelines.

The Quantaris Difference

Why Clients
Choose Quantaris

Five principles that define every engagement.

◆

Senior Engineer, Every Engagement

Your project is led by a principal engineer with 30+ years of direct experience — not passed to a junior team. You get the person whose name is on the proposal, from kickoff through close-out.

◊

Vendor-Neutral Independence

Quantaris holds no vendor partnerships, reseller agreements, or licensing affiliations. Every recommendation is based purely on technical merit and the client's operational requirements — not on commercial relationships.

✦

Operator-Side Perspective

Having worked on both the contractor and plant-owner side of major industrial projects, Quantaris understands how to protect the owner's interests while maintaining productive relationships with EPC teams and vendors.

♦

Integrity & Conflict-Free Practice

The firm maintains a written conflict-of-interest policy and declines any engagement that cannot be undertaken with complete professional independence.

✶

Breadth Across the Technical Lifecycle

From concept study and FEED through detailed design, factory testing, site commissioning, and operational support — Quantaris covers the full technical lifecycle. Clients benefit from a single, experienced point of contact who understands how decisions made at FEED impact commissioning outcomes two years later.
