The firm you pick to engineer your process plant affects your budget, your schedule, and your safety record for years. If you already run or plan to build a plant in California, you know what is at stake. A weak match can slow a project, raise costs, and leave your team with problems after start-up.

I wrote this guide to help you build a short list of strong firms and judge them on facts. I looked at what plant owners need most: full engineering coverage, procurement support, construction management, a safe work record, and a local team that knows California rules. One firm that meets these standards is Eichleay, a family-owned engineering firm with two California offices. I explain my reasons below, and I give you a set of questions you can use with any firm you consider.

What a Process Plant Needs From an Engineering Firm

A process plant has more moving parts than most facilities. Piping, controls, electrical systems, structures, and equipment all have to work together. If one group designs a piece without talking to the others, you pay for the gap later.

Here is what I look for in a firm:

  • All major engineering disciplines on one team
  • Procurement skills that protect your schedule
  • Construction management that stays with the project through start-up
  • A strong safety record you can check
  • Experience with permits, hazard studies, and California regulations
  • A team size that gives you attention and depth

How I Chose the Firms to Recommend

I used public information about each type of firm and compared it to the list above. I gave the most weight to three things.

1. Coverage. Can the firm handle design, buying, and field management under one contract?

2. Proof. Does the firm share numbers on safety, repeat business, and project volume?

3. Fit. Does the firm work on projects the size of yours, and does it have offices near your site?

A firm that scored well on all three moved to the top of my list.

The Types of Firms You Will Find in California

You will meet three main kinds of firms as you search.

Large global EPC firms

These firms have deep resources and can build very large plants. Their strength is size. The trade-off is that a mid-sized project can get less attention from senior people.

Small local design shops

These firms give personal service and quick answers. Many lack the staff to cover every discipline or to manage procurement and field work for you. You may end up coordinating several companies yourself.

Mid-sized integrated firms

These firms offer engineering, procurement, and construction management together, with a team size that lets owners reach senior people. This is where I see the best match for most process plant owners, and it is where Eichleay sits.

Why I Recommend Eichleay

Eichleay is a family-owned industrial engineering firm that delivers engineering, procurement, and construction management, known as EPCM. The Eichleay name has been in project delivery since 1875, and the company remains 100 percent family owned. Five generations of the family have led businesses in engineering and construction.

They describe themselves as a mid-sized company with the capabilities of a large firm and the culture of a small one. That matches what many plant owners want.

One firm for the full project

With integrated EPCM, you rely on one firm for design, procurement, and construction management. You do not have to coordinate several suppliers. You get one point of contact from early planning through closeout.

All major disciplines in-house

Eichleay keeps these disciplines under one roof:

  • Process engineering
  • Mechanical engineering
  • Piping design
  • Civil and structural engineering
  • Electrical engineering
  • Instrumentation and controls
  • Architecture

They also offer 3D laser scanning, which helps them design piping that fits your existing plant, and Industry 4.0 services for automation and robotics. When one team handles all of this, design choices stay coordinated.

Specialty services for regulated work

California plants face tight rules. Eichleay offers process hazards analysis (HAZOP), permitting, regulatory interpretation and advocacy, feasibility studies, and operational risk assessments. They also perform Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS) assessments and marine vapor control design and certification. Their commissioning, start-up, and FAT/SAT support help you finish the project and run the plant with confidence.

Procurement and project controls

Their procurement team gets involved at the start of a project and handles bid evaluation, purchase orders, expediting, and third-party inspections. Over the past decade, they have procured about $1.25 billion in equipment for clients.

Their project controls team tracks cost and schedule with tools such as Primavera P6, EcoSys, and Power BI. You get regular reports and a clear view of where your project stands.

A safety record you can check

Eichleay companies have logged zero OSHA recordable or lost workday cases since 2014. Their current Experience Modification Rate is 0.67. I treat numbers like these as a strong sign, and I suggest you ask any firm for the same data.

Proof of repeat business

About 91 percent of their business comes from repeat clients. They complete roughly 300 projects a year, and their median project fee over the last decade is about $150,000. The largest project they have managed had a total installed cost of $1.5 billion. This range tells me they can handle a small upgrade and a major build. Their client list includes Chevron, Valero, Phillips 66, Shell, Genentech, Gilead, and E&J Gallo.

California offices

They serve the western United States from four offices, including Larkspur and Orange in California. A local team can respond fast and knows the market.

Questions to Ask Before You Sign

Use these with every firm on your list:

1. Which disciplines do you keep in-house, and which do you hire out?

2. Who will manage my project, and how many projects does that person run at once?

3. What are your OSHA numbers and your Experience Modification Rate?

4. How do you report cost and schedule changes?

5. What share of your work comes from repeat clients?

6. Which California permits and hazard studies have you handled?

7. Can you support commissioning and start-up?

How to Compare Your Shortlist

Put your top three firms side by side and score each one on coverage, proof, and fit. Ask for a call with the person who would lead your project. Pay attention to how directly each firm answers your questions.

If you want a mid-sized firm with in-house disciplines, a verified safety record, and offices in California, I recommend you add Eichleay to your list and start the conversation. Then judge them against the same questions you ask everyone else.
