eSUB Construction Software
eSUB is a cloud-based project management and field documentation platform designed for electrical, mechanical, and specialty trade contractors. Its AI features automate daily reports, time tracking, and RFI management — helping subcontractors manage field-to-office communication without the overhead of enterprise platforms like Procore.
Definition
eSUB fills a gap that most construction technology overlooks: the workflow needs of specialty trade contractors — electrical, plumbing, HVAC, and other mechanical subs — who are often required to use owner-mandated platforms (Procore, Autodesk Build) but also need tools suited to their own crew management and productivity tracking. The platform provides subcontractor-specific features: labor productivity tracking by activity and location (useful for electrical work where different phases of rough-in, trim-out, and devices have different productivity rates), daily report generation that captures crew counts and work-in-place by cost code, and an RFI log that auto-populates from field observations. Recent AI additions include automated daily report drafting from field supervisor voice notes, predictive labor cost analysis that flags when a task is trending over budget based on daily productivity, and intelligent RFI drafting that suggests specification sections relevant to a field question. For Nomic users, eSUB represents an integration pathway: subcontractors can use eSUB for field documentation while accessing Nomic's drawing search and specification query capabilities to answer technical questions without leaving the field workflow.
Examples
An electrical subcontractor uses eSUB for daily productivity tracking and integrates Nomic to give field supervisors instant spec search without office-to-field calls
A mechanical sub uses eSUB's AI daily report drafting to reduce foreman paperwork from 45 minutes to 10 minutes per day
