CAUSES

Why Estimation Bottlenecks Happen

Nexarc eliminates these gaps with integrated, tool-native estimation that combines modeling, material breakdown, and real-time system validation.

Manual input errors from disconnected files.
No cross-check between actual and taken by software take off.
Lack of BIM-layer output for GC/client approval.
PDF overlays that don’t align with 3D coordination.

TESTIMONIALS

Client Outcomes

Before working with your team, our processes were slow and required constant follow-ups. Deliverables often took longer than expected, which made it difficult to meet tight deadlines. Since partnering with you, everything runs smoother and results are delivered with far greater efficiency.

Project Manager

Dallas

Prior to using your services, we struggled with inconsistent quality and limited visibility into progress. Tasks that should have been simple became time-consuming. Now, we have a reliable workflow and clear communication that helps us stay on track.

Operations Lead

Chicago

Before collaborating with your team, managing day-to-day operations was overwhelming and prone to errors. Turnaround times were unpredictable, and revisions caused delays. With your support, our processes are streamlined and far more dependable.

Business Owner

San Diego

Earlier, our team spent excessive time coordinating work and correcting mistakes. The lack of structure slowed growth and impacted performance. Since adopting your services, we’ve seen faster execution and more confidence in our outcomes.

FAQ

Quick Answers

What exactly do I get in the free 8-hour trial task?

A BIM preview or layered take-off sheet, plus load analysis and equipment suggestions — delivered within 2–3 business days.

Can I start if I only have a PDF or sketch, not a full DWG?

Yes — we accept PDF, DWG, and even basic marked-up layouts. We’ll flag if something is missing.

How do you align to compliance like Title 24, ASHRAE, or EU codes?

Our team actively designs to these standards and uses platform-specific compliance modeling (e.g., HAP, Daikin, local codes).

Will I have to go through a sales pitch first?

No — your first interaction is with a project lead or engineer. We believe estimation starts with clarity, not a pitch.

Can I choose what task to trial — BIM vs. Take-Off vs. Load?

Yes — the 8-hour trial can be scoped around your most urgent deliverable.

Do you return editable files or just PDFs?

We return layered source files (DWG, XLSX, RVT) upon approval or post-trial if you continue.
