Bid Estimating — Industrial Material & Quantity Takeoff Portal
The Problem & Bottlenecks
System Bottlenecks & Technical Friction
Specialty industrial contractors required exact bill-of-materials takeoffs for structural steel, piping, and concrete to avoid severe material over-ordering or disastrous budget under-runs on competitive bids.
Our Engineering Approach
Architecture Design & Implementation
We developed a robust web application allowing contractors to submit large plan sets, specify customized waste buffer percentages, and receive detailed itemized spreadsheets mapped to standard MasterFormat codes within 24 to 48 hours.
