MEP Design-Build · South Texas
Five trades.
One point of
accountability.
Beyer Design Build brings plumbing, mechanical, electrical, technology, and BIM-driven fabrication under a single contract — designed together, coordinated in one model, and installed by the crews who built their names on it.

The Partnership
One team, drawn from
five proven shops
Each trade in the Beyer Design Build partnership is a standing company with its own crews, licenses, and track record. Together, we come to your project as one pre-coordinated MEP subcontractor — not five separate subs meeting for the first time at bid — so coordination happens before the first hanger goes in.

Automated coil-line ductwork, spiral and custom fittings, precision laser cutting, and full BIM coordination — Revit, AutoCAD MEP, and Navisworks clash detection — shipped from a Selma, Texas production floor.
velocitysheetmetal.com T-100 · Technology J3 Automated SystemsNetworking, Security & Building Automation
Structured cabling and networking, security, surveillance, and access control — plus building automation (BMS) controls that tie the mechanical, electrical, and plumbing systems into one intelligent front end. The connective layer that makes the whole building respond as a single system.
j3as.comHow We Deliver
Designed once.
Built without clashes.
Every project moves through the same sequence — the same one our trades already run on their own work, now shared across all five scopes.
01
Design & Estimate
Site-specific assessments and load calculations across every trade produce one transparent, buildable scope and price.
02
BIM Coordination
Plumbing, duct, pipe, conduit, and cable pathways are routed together in a single model. Clashes get resolved on screen, not on scaffolding.
03
Prefabrication
Spool drawings go straight to our own production floor — coil-line duct, cut and welded pipe, assemblies staged by area.
04
Installation
Licensed crews from each trade install to the coordinated model on a shared schedule, sequenced to keep your site moving.
05
Commissioning
Systems are tested, balanced, and brought online under one automation front end — backed by the service departments that stand behind them.
Why Design-Build
Why owners hire
one team, not five bids
Single Accountability
One contract, one schedule, one team responsible for the entire MEP scope. No finger-pointing between trades — the coordination problems that stall projects belong to us, not you.
Coordination Before Construction
Because our trades share a model and a campus, conflicts between duct, pipe, and conduit are engineered out during design. Fewer RFIs, fewer change orders, fewer surprises in the ceiling.
Shop-Built Speed
In-house fabrication means the model feeds the machines directly. Assemblies arrive on site ready to hang, compressing schedules and cutting field labor on every floor.
Where We Build
Commercial first.
Residential in our roots.
Every trade in the partnership delivers design-build for both commercial and residential work. Commercial is where we focus — and the same coordinated crews build custom homes through Beyer Custom Homes.
Primary Focus
Beyer Custom Homes
Commercial
Office, retail, industrial, healthcare, and multifamily projects across South Texas — full MEP and technology scopes under one contract, coordinated in BIM, fabricated in-house, and installed on your schedule. If your project has a general contractor, a pro forma, and a deadline, this is what we're built for.
Residential
Through Beyer Custom Homes, the same trades design and build legacy custom homes and whole-home remodels — new construction and renovations crafted with the coordination and quality of a commercial job, at the scale of a family home.
