Why Hydra

The overflow team that actually speaks contractor

The offshore drafting shops are cheap for a reason — no field experience, slow communication, and endless revision loops. Hydra is the opposite, wherever you're located.

About

Built by a team that's run the work

Field experience first. That's where the estimating, the drawings, and the project management all started — and it's still how we grow the team today.

Hydra Constructors is built on a career spent entirely in glass and glazing. Our roots start on the field side in 2006, installing glass, windows, and commercial glazing systems — and that hands-on foundation still shapes every drawing and estimate we produce today.

Over the years that experience grew from the field into estimating and project management, leading commercial and high-end residential facade projects across Southern California. We deliver curtain wall, storefront, all-glass, and residential window systems from preconstruction through closeout, including OSHPD, DSA, and PLA-compliant work with full attention to waterproofing, sealants, and fire-rated assemblies.

What sets Hydra apart is a focus on constructable solutions. We know the local means and methods of construction and erection, and we understand the people and the vendors, how they work, and what they offer. That means our drawings and takeoffs reflect how the job actually gets built and priced, not just how it looks on paper.

Our team is led by a PMP-certified project manager with a Bachelor of Science in Mechanical Engineering. That mix of field experience, engineering, and project management means your shop drawings, takeoffs, and estimates are handled by people who understand constructability, sequencing, and the numbers behind the job. We work in the tools the industry runs on, including AutoCAD, Logikal, Bluebeam, and Procore.

Hydra Constructors is a California S-corporation built on being honest and reliable. From a single storefront to a full building facade, you get accurate, fabrication-ready work delivered on your deadline. Send us your plans and let's get started.

Today Rami brings that full-cycle perspective to every project. He has led commercial and high-end residential facade work across Southern California, delivering curtain wall, storefront, all-glass, and residential window systems from preconstruction through closeout.

Honest, reliable, and detail-driven, Rami started Hydra Constructors to build a team contractors can trust with their drawings, takeoffs, and project support — held to the same standards he's worked by since day one on the job site.
