What Goes in a Tunnel / Underground Daily Report?

A Tunnel / Underground daily report should include TBM Advance, SEM/NATM (Sequential Excavation), Ground Support & Monitoring, Underground Safety, Final Lining & Finishes. The industry-standard approach is a POD (Plan of Day) — a morning coordination document that covers what WILL happen today plus what DID happen yesterday. Here is a complete checklist for writing a Tunnel / Underground daily report that covers all 61 fields a proper report needs.

The Complete Tunnel / Underground Daily Report Checklist

1TBM Advance

TBM Face Station TBM Advance (today) TBM Advance — Rings Installed Ring Width TBM Thrust Force

Document tbm advance details while they are fresh — end-of-day recall loses critical details

2SEM/NATM (Sequential Excavation)

Excavation Round Round Length Excavation Area Ground Class Encountered Shotcrete Applied — Initial

Log soil conditions and utility locates before digging — one miss can shut down the whole site

3Ground Support & Monitoring

Convergence Monitoring — Points Read Convergence — Max Movement Settlement Monitoring — Surface Settlement — Max Movement Groundwater Inflow

Document ground support & monitoring details while they are fresh — end-of-day recall loses critical details

4Underground Safety

Gas Monitoring — CH4 Gas Monitoring — CO Gas Monitoring — H2S Gas Monitoring — NO2 Ventilation — Adequate

Track safety observations in real-time — waiting until end of day means losing critical details

5Final Lining & Finishes

Final Lining Concrete Final Lining — Type Waterproofing Membrane Membrane Type Drainage System (behind lining)

Document final lining & finishes details while they are fresh — end-of-day recall loses critical details

Why Generic Templates Fall Short

Generic daily report templates have 20 to 30 fields. A proper tunnel / underground daily report needs 61 fields across 5 sections. Here is what generic templates miss:

TBM Advance

SEM/NATM (Sequential Excavation)

Ground Support & Monitoring

Final Lining & Finishes

These sections contain fields that are specific to tunnel / underground construction — fields that a generic template simply does not have.

The POD Approach: Speak Instead of Type

Instead of filling out 61 fields manually, speak for 5 minutes. POD's AI extracts all of this from your voice report automatically and maps it to the correct fields in your tunnel / underground template.
