Viega Project Spotlight – Life Sciences Lab and the Letsos Company

Delivering Speed, Precision and Scale on a Life Sciences Lab Renovation

Some projects are about meeting deadlines. Others are about solving technical challenges. A few demand both, at scale, under pressure and with no margin for error.

At a life sciences lab in Spring, Texas, the laboratory renovation did all three. The fast‑paced project called for major mechanical, electrical and plumbing upgrades to support advanced research environments. But behind the drawings and specifications was a more familiar challenge for contractors and engineers alike: how do you move faster, stay clean and deliver flawless work when nearly everything is exposed and everyone is watching?

For the Letsos Company, a Houston‑based union mechanical contractor, the answer was press technology, applied at a scale few projects demand. For Viega, the project became a defining industrial milestone, demonstrating how press systems, when paired with planning, training and collaboration, can transform what’s possible on high‑stakes laboratory jobs.

From a Modest Scope to a Major Industrial Opportunity

The project initially began as a focused domestic water installation valued at roughly $250,000, using small‑diameter Viega copper press fittings. But as system requirements were reviewed and schedules tightened, Letsos identified opportunities to expand press solutions well beyond the original scope.

Through close coordination between Letsos field leadership and Viega’s commercial and industrial teams, the project grew to include:

• Large‑diameter ProPress®
• MegaPress® for steel piping
• Cleaned‑and‑bagged fittings for specialty systems
• Laboratory gas, vacuum, instrument air and chilled water lines

That expansion ultimately pushed the project into the $650,000–$800,000 range, with press technology used across nearly every applicable system.

“What made this project special wasn’t just the size,” said Cameron Haines, District Sales Manager at Viega. “It was Letsos wanting to use Viega beyond the traditional domestic water scope and trusting us across every application they could.”

Cleanliness and Scale Under Real‑World Pressure

One of the project’s defining challenges was scale. The expanded scope required approximately 8,000 fittings, ranging from ½ inch to 4 inches, all of which had to be cleaned, bagged and delivered in tightly phased windows. Many of the systems, including nitrogen, helium, vacuum and instrument air, required strict cleanliness protocols and specialized prep procedures.

Executing that volume on an aggressive timeline demanded constant coordination across:

• Letsos field supervision and purchasing
• Viega’s commercial and industrial teams
• Distribution and logistics partners
• Cleaning and bagging operations

At peak activity, up to 70 plumbers were working on site. Any delay in material flow risked stopping production entirely.

“Coordinating 8,000 cleaned‑and‑bagged fittings on three‑week cycles while keeping 70 plumbers productive required constant communication and alignment across teams,” Haines said.

Why Press Made the Difference

For Letsos, press technology wasn’t just a faster joining method. It was the only way to meet the life sciences lab’s schedule without compromising quality or safety.

Press also eliminated open flame from the jobsite, an important factor in an active laboratory environment. But speed and safety were only part of the story.

On the project, nearly 90% of the piping remained exposed, meaning alignment, consistency and visual quality mattered just as much as performance.

“You’re not taking craftsmanship away with press. You’re adding to it,” Venable said. “When everything is exposed, uniform and perfectly aligned, that’s what owners notice.”

The life sciences lab’s leadership noticed as well. According to the Letsos team, executives walking the corridors consistently commented on the clean appearance and uniformity of the installed piping.

Training, Trust and Field‑Level Support

Another critical component of success was on‑site training and technical support. Viega worked directly with Letsos’ crews to ensure installers were confident using multiple systems and diameters, reinforcing consistent installation practices across dozens of tradespeople.

“It’s always a plus to have Viega come out and do training for the guys,” Venable said. “They get a lot out of it, especially when you’re working across so many systems.”

That collaboration extended beyond the field. Getting press systems approved across multiple applications required RFIs, technical validation and conversations with the life sciences lab stakeholders. The effort paid off: successful execution on the project helped Viega gain inclusion in the life sciences lab’s master specifications, opening the door to additional work, including at an adjacent facility.

“If Viega isn’t on the spec, our first question is, ‘Why not?’” said Galen Vera, Purchasing Agent at the Letsos Company. “And then we work to get it there.”

A Blueprint for Future Industrial Projects

For Letsos, the life sciences lab renovation reinforced its reputation as a top‑tier union contractor capable of delivering high‑visibility, high‑pressure work at scale.

“This job doesn’t just reflect the project, it reflects our company,” Vera said. “We buy the best so we can deliver the best.”

For Viega, the project demonstrated how press technology, supported by planning, logistics and partnership, can scale into demanding industrial environments.

For contractors and engineers facing similar challenges, the life sciences lab project offers a clear takeaway: when systems are evaluated holistically, crews are trained properly and teams collaborate early, press technology doesn’t just replace traditional methods. It expands what’s possible on the jobsite.
