Pre-Construction Estimating

Pre-Construction Estimating Solutions Delivering Excellence and Value

Precision Takeoffs. Smarter Engineering. Stronger Project Outcomes.

Precision Takeoffs

On-Screen Takeoff & Quantity Takeoffs You Can Rely On

Our OST/QTO services deliver precise, structured quantity takeoffs that form the backbone of accurate construction cost estimates. Whether you need door schedules, hardware counts, or Division 10 BOQs, our pre-construction estimator team ensures numbers match drawings.

Zero Errors

Quality Check Process That Ensures Accuracy Before You Order

Aorbis applies a multi-stage quality check process to every takeoff and submittal. Our QC prevents mismatches between specification writing and field requirements.

Drawing-spec cross-verification

ADA, fire-rating & code validation

Product compatibility checks (hardware, finishes)

Missing-item & duplicate detection

Streamlined Construction Solutions for Cost, Timing, and Installation

From early cost analysis to final installation, Aorbis streamlines every step of Division 8 and 10 delivery. Our integrated approach—Value Engineering, Just-In-Time Delivery, and Installation Support—helps GCs and estimators reduce risk, maintain schedule certainty, and eliminate avoidable jobsite complexity. Each service is designed to cut pre-construction costs, simplify coordination, and ensure accurate, installation-ready packages.

Our Value Engineering process analyzes alternatives, reduces unnecessary spend, & improves lifecycle value. Aorbis’ VE recommendations are spec-aware, compliant, & installer-friendly.

JIT coordination reduces onsite storage, damage, and double-handling. We align deliveries with install sequences to keep your schedule intact and your pre construction costs lower.

We deliver installation-ready schedules, verified hardware sets, and placement diagrams so installers get the right product in the right location the first time. This reduces RFIs, change orders, and on-site delays.
