The Problem & Bottlenecks

System Bottlenecks & Technical Friction

MEP systems represent 30% to 45% of total commercial building budgets. Inaccurate ductwork weight calculations, overlooked pipe fittings, or mismatched HVAC equipment capacities routinely caused tens of thousands of dollars in contractor losses on complex projects.

Our Engineering Approach

Architecture Design & Implementation

We engineered a specialized MEP takeoff application capable of handling complex mechanical drawings. Implemented automated duct surface area and poundage formulas, comprehensive piping schedules by diameter and material, and unified equipment schedules across plumbing, hydronics, and electrical services.

Technical Architecture

System Subsystem Breakdown.

6 Core Subsystem Modules
01

HVAC sheet metal ductwork surface area and poundage calculation engine factoring in SMACNA standards

02

Piping schedule module calculating pipe lengths, fittings, valves, and insulation by trade

03

Plumbing fixture and drainage waste vent (DWV) takeoff system mapped to architectural schedules

04

Equipment schedule cross-referencing tool linking chillers, boilers, RTUs, and pumps directly to electrical feeds

05

Export engine generating structured division-by-division spreadsheets for mechanical subcontractors

06

Secure cloud storage managing multi-discipline BIM coordinate plan sets and architectural addenda
