Frequently Asked Questions

Getting started is simple. Reach out through our contact form—we’ll walk you through the next steps and answer any questions along the way.

We deliver principal-level engineering on every project, not junior-level drafting. Our designs are built from first principles - real loads, real constraints, real site conditions - never recycled templates. We operate on a fast disciplined 5-phase process that blends speed with accuracy, backed by an elite QA/QC system that eliminates field confusion and rework.

Clients choose ONYX Dynamics Group because our drawings are clean, buildable, and code-correct, our communication is transparent, and our industrial grade thinking reduces risk for contractors, architects, and owners. We’re a precision-driven, minority-owned firm built on strength, clarity, and engineered execution.

You can reach us anytime via our contact page or email. We aim to respond quickly—usually within two business days.

We’ll review your project details and provide a structured proposal outlining scope, timeline, and deliverables.

We use a hybrid pricing model designed for clarity and fairness. Defined‑scope projects are billed as fixed‑fee packages, giving clients upfront cost certainty with no surprises. When a project’s scope is evolving or not fully defined, we apply hourly engineering rates to keep the process flexible and efficient. For recurring partners, ONYX Dynamics Group offers monthly retainers that provide priority access, predictable billing, and faster turnaround.

Working with us is a structured, fast, and highly professional experience. We follow a clear 5‑phase process—Intake > Engineering > QA/QC > Delivery > Closeout—so clients always know exactly where their project stands. Communication is direct, timelines are transparent, and every deliverable is produced and reviewed by senior‑level engineers.

Clients describe the experience as clean, predictable, and low‑friction: no chasing updates, no unclear drawings, no surprises in the field. Our goal is simple—make your job easier by delivering precise, buildable engineering that reduces risk and accelerates progress.

Based in Bentonville, Arkansas we support clients throughout the state with precision design, code‑compliant solutions, and efficient project delivery

As we continue to grow, we’re planning to expand into neighboring states, extending the same level of technical excellence and reliability that defines our work today.

Not yet. ONYX is currently in the process of securing the appropriate licensing and insurance required for engineering services.

For projects that require the involvement of a Professional Engineer (PE), we actively partner with qualified Subject Matter Experts (SMEs) and licensed engineering professionals to ensure all work meets state requirements, industry standards, and regulatory expectations.

This approach allows us to deliver high‑quality, code‑compliant solutions while we complete the formal licensing process.

ONYX produces all engineering work in-house, and a licensed Structural PE partner performs the final review and stamp. This gives you boutique-level speed with full code-compliant authority.

Our process begins with a structured intake meeting to define scope, site conditions, and client priorities. From there, we move through engineering design, internal QA/QC review, and final delivery - ensuring every drawing meets our standards for accuracy and clarity.

Turnaround depends on project complexity. Small tenant improvement typically take 5 - 14 business days, while full mechanical or architecture systems may require 2 - 4 weeks. We prioritize schedule transparency and communication milestones throughout.

We use AutoCAD, Revit, Fusion 360, Inventor and RISA for design and documentation, supported by internal QA tools for version control and consistency. Our workflow integrates directly with client portals and cloud storage systems.

A Principal Engineer at ONYX Dynamics Group is the highest technical authority in the company—the person responsible for system‑level decisions, engineering standards, and the overall technical direction of every project. Unlike firms that push work down to junior staff, ONYX ensures that all projects are led, reviewed, and finalized by a Principal Engineer.

Every Proposal includes:

• Scope

• Deliverables

• Timeline

• Assumptions

• Exclusions

Clients always know exactly what they’re getting.

Revisions at ONYX Dynamics Group follow a structured, engineering-driven process to designed to keep projects moving without confusion or scope creep. Every revision request is reviewed by a Principal Engineer to determine what’s needed and how it affects the project.

How the revision process works:

• Clients sends revisions request - usually after GC/Architect comments or field changes

• ONYX reviews the request to confirm whether it’s a clarification, correction, or new scope

• Revisions are completed within the agreed turnaround window

• Updated drawings are issued with clear clouding and revision notes

• A revision log is maintained for transparency and permitting

What counts as a revision?

• Clarifications based on comments

• Minor adjustments that don’t change the original scope

• Corrections identified during QA/QC or by the client

What counts as new scope?

• Added equipment

• Layout changes driven by the client or architect

• New rooms, new loads, or new systems

• Any change that alters the original design intent

These are handled as change orders, not revisions.
