Where Precision Meets Professional Low Voltage Design
Expert Low Voltage Design & Drafting for Architects and Integrators
Architects and low voltage integrators rely on OnMark Design for precise, code-compliant structured cabling drawings — from design development through construction documentation. RCDD-certified, BIM-capable, and built for complex projects.
We live in the world of structured cabling — Telecom, AV, Security, Nurse Call, RTLS, DAS, ERRCS, CCTV, CATV, Card Access, and WiFi. This isn't a side service — it's our entire focus, and that depth of specialization shows in every drawing we deliver. Whether you're a design firm that needs a dedicated low voltage consultant, or a contractor needing clean shop drawings, this is our entire world.
02
Intelligent, Data-Embedded BIM
Our BIM symbol families carry embedded parameter data that automatically populates and updates your project schedules in real time. Every device placed is instantly tracked, counted, and scheduled — eliminating manual takeoffs and catching errors before they reach the field.
03
Legibility-First Visual Standards
Your drawings speak before your team does. Every deliverable is built around on-site clarity — instantly readable by installers, field coordinators, and engineers without a second glance or a follow-up call.
What We Offer
Services Built for Design & Construction
Whether you're an architect coordinating low voltage into a design package, or a contractor who needs clean, submittable shop drawings, every engagement is scoped to your project's complexity and timeline.
Design
CAD / BIM Drafting Services
Architects: get a dedicated low voltage designer embedded in your project from SD through CDs. Contractors: get clean, coordinated structured cabling plans — TSO, AV, RTLS, telemetry, DAS, ERRCS, CCTV, CATV, Card Access, WiFi, and more — that pass submittal review the first time.
For integrators and contractors with in-house drafting teams: inconsistent templates and ad-hoc layer schemes drag down every project. We audit and rebuild your CAD/BIM standards from the ground up — elevating drawing fidelity, enforcing consistency, and ensuring your team's output reflects the quality of your work on every job.
A properly documented TR is the backbone of any low voltage system. We consult on equipment layout and pathway coordination, delivering full documentation packages that meet TIA standards and give your team a clear, buildable reference from design through closeout.
Bring a second set of expert eyes to your low voltage design before it goes to construction. As an RCDD-certified designer, we review shop drawings and design documents for code compliance, TIA standards alignment, and constructability — catching costly errors before they reach the field.
Not sure which service fits? In 30 minutes we'll assess your current workflow, identify the gaps, and outline exactly what it would take to get your drawings where they need to be. No commitment, no pressure — just a straight conversation.
The low voltage industry deserves better drawings. Architects increasingly need a qualified low voltage designer embedded in their project team — someone who can carry structured cabling design from schematic design through construction documents. OnMark Design fills that role.
Based in Studio City, CA, we serve architects, network integrators, and contractors across the country — providing CAD and BIM services built exclusively around the needs of low voltage construction. Our structured cabling work spans commercial office, K–12 and higher education, and healthcare environments, from design through closeout documentation.
At the heart of everything we do is a data-driven design philosophy: our BIM symbol families are built with embedded parameter data that automatically populates and updates your project schedules as you design — so your team spends less time on manual takeoffs and more time on what matters.
