Engineering Delivery Suite

Seven purpose-built modules. One continuous engineering spine.

Engivaryn AI replaces fragmented engineering spreadsheets and disconnected tools with seven dedicated modules. From RFP intake and commercial proposals to design calculations, multidisciplinary QA/QC, construction support, and record closeout, every phase shares data seamlessly so work is never re-keyed.

Inside Each Module

How each module powers your engineering practice.

Swipe through modules →

  • 01RFP & Criteria Extraction

    Intake

    Extract requirements, deliverables, and missing inputs from client RFPs.

    The Opportunity Intake module parses incoming RFPs, owner design criteria, and municipal standards in seconds. It extracts key deliverables, highlights compliance requirements, and automatically flags missing inputs like site surveys or geotechnical reports. AI scores project fit and routes the opportunity directly to the right discipline lead so you only pursue profitable, deliverable work.

    What this module includes

    • Parses 20+ page RFP documents and design briefs with direct source citations.
    • Identifies missing technical inputs early (site surveys, geotech data, utility maps).
    • Evaluates win probability, commercial attractiveness, and discipline resource fit.
    Engivaryn AI: RFP & Criteria Extraction dashboard
  • 02Scope & Fee Matrix Builder

    Proposals

    Build structured work packages, discipline hours, and defensible fee estimates.

    The Proposals module turns qualified opportunities into structured, margin-protected commercial bids. It breaks projects into clear discipline work packages—from site analysis to detailed structural design and MEP coordination. Real-time commercial signals guard your rates, calculate contingencies, and alert you to missing scope allowances before proposals are submitted to clients.

    What this module includes

    • Structures discipline-specific work packages with estimated hours and fee breakdowns.
    • Detects missing scope allowances (such as geotechnical testing or field support).
    • Calculates blended hourly rates, contingency buffers, and commercial fee health.
    Engivaryn AI: Scope & Fee Matrix Builder dashboard

How it runs

Two ways to run Engivaryn AI — same platform, same ongoing subscription price. Only the onboarding may differ by your requirements.

Cloud (SaaS)

Runs in Nestack’s managed cloud — the fastest way to go live. We handle hosting, updates and scaling so your firm logs in and starts working; intake, proposals, diagnostic synthesis and firm knowledge are live without infrastructure to stand up.

Private / self-hosted

The same platform deployed inside your own infrastructure — your cloud, VPC or on-prem — for firms bound by strict client confidentiality. Consulting briefs, stakeholder interview recordings, diagnostic matrices and client data never leave your environment, and the ongoing subscription price stays the same.

FAQ

Questions principals tend to ask first.

01What does Engivaryn AI cost?

Engivaryn AI is billed on a straightforward monthly subscription covering your whole engineering practice, starting at the fee shown above. There are no per-seat penalties or hidden feature surcharges. A one-time onboarding fee, scoped to your firm's data, integrations, and deployment model, gets you fully live before your first cycle.

02What is included in the subscription?

Your subscription gives your firm complete access to all eight core operational modules: Opportunity Intake, Proposals, Project Planning, Engineering Design, Technical Review, Project Delivery, Project Closeout, and the firm-wide Dashboard. It also includes multi-model frontier routing, discipline criteria libraries, ongoing updates, and shared workspace access for principals, PMs, discipline leads, and review engineers.

03Is there a one-time onboarding or setup fee?

Yes. Onboarding is a separate, one-time investment that gets your engineering practice fully configured before the monthly subscription begins. Depending on your scope, it covers historical project archive imports, discipline design criteria calibration, integration with your CAD/BIM environments, ERP/accounting systems, and role-based training for your team.

04Does Engivaryn AI replace AutoCAD, Revit, Civil 3D, or our structural analysis tools?

No. Engivaryn AI does not replace your engineering authoring applications—such as CAD, BIM, FEA, or hydraulic modeling software (Revit, Civil 3D, ETABS, or Bentley). Instead, it sits directly above them as the operational control spine—governing requirements, design criteria, calculations, staffing, interdisciplinary QA/QC, and issued records so your models stay linked to contract deliverables and commercial margins.

05How does Engivaryn AI support Engineer of Record (EOR) responsible charge?

Engivaryn AI is built to respect professional engineering licensure and state board rules. While AI accelerates pre-QA checking, calculation retrieval, cross-sheet reference validation, and specification consistency, AI never makes responsible-charge decisions. Final review gates require authenticated PE/EOR digital verification, preserving unambiguous legal responsibility.

06How does Engivaryn AI connect proposal scope directly to project labor and fees?

The platform enforces an unbroken operational chain: Requirement → Scope → Task → Deliverable → Discipline → Role → Hours → Rate → Fee. Modifying a deliverable automatically recalculates staffing and fees, while built-in AI checks flag discrepancies—such as unbudgeted utility coordination hours or missing senior review time—before client submission.

07Can we see Engivaryn AI working with a project like ours before subscribing?

Yes. In our live walk-through, we demonstrate the platform using real-world engineering project workflows tailored to your specific disciplines—showing how an opportunity moves from RFP intake and calculation traceability to multidisciplinary QA/QC and record closeout.
