3 Elongation Readings Off by 6% —
The Stressing Log Is in the Super's Truck
The PT crew stressed 14 tendons yesterday. Three elongation readings are off by 6%. The stressing log is a clipboard that's already in the superintendent's truck. POD logs PT stressing data, elongation readings, and tolerance checks by voice — ACI 318 compliance documented before the jack comes off the strand.
How Post-Tension Records Disappear Between the Jack and the Report
Four failure points that turn a straightforward stressing operation into a structural documentation crisis.
Elongation Readings on a Clipboard Nobody Can Find
The PT crew records gauge pressure and elongation for each tendon on a paper stressing log. By the time the superintendent gets to the trailer, three pages are in his truck, one is on the formwork, and the engineer is asking for the deviation calculation on tendon 9. The answer is a shrug and a promise to "look for it."
Manual Deviation Calculations Across 200 Tendons
Each tendon has a theoretical elongation value from the PT shop drawings. The actual elongation must fall within ACI 318 tolerance. On paper with a calculator, computing percent deviation for 200 tendons across a single pour is an error factory. One transposed digit turns a passing tendon into a structural question mark.
Out-of-Tolerance Tendons Discovered Days After Stressing
The engineer reviews handwritten stressing logs two days after the pour. Three tendons show elongation 6% above theoretical. The slab is already stripped, shored, and loaded. Now you are in a structural engineering investigation because nobody flagged the deviation while the jack was still on the strand.
Jacking Sequence Records Missing for Inspection
ACI 318 requires documented evidence of stressing sequence, lock-off pressure, and elongation for every tendon. When the special inspector arrives, the stressing log is a stack of handwritten pages with coffee stains. Missing tendon records mean re-inspection, potential re-stressing, and a schedule delay that cascades through every floor above.
From Clipboard to Compliance in One Voice Command
POD captures every elongation reading at the jack, calculates deviations instantly, and maintains the ACI 318 record your inspector requires.
Voice-Log Every Tendon at the Jack
The PT operator speaks the tendon ID, gauge pressure, initial mark, and final elongation as each strand is stressed. POD captures the data in real time, links it to the slab pour and jacking sequence, and stores it permanently. No clipboard, no handwriting, no data entry at the end of the day.
Instant Deviation Calculation Against Theoretical
POD automatically computes the percent deviation from the theoretical elongation for every tendon the moment the reading is logged. Out-of-tolerance tendons are flagged immediately on the operator's device and the superintendent's dashboard. The engineer gets a notification before the crew moves to the next strand.
ACI 318 Compliance Documentation — Always Inspection-Ready
Every tendon record in POD includes strand ID, sequence number, gauge pressure at initial stress, gauge pressure at lock-off, measured elongation, theoretical elongation, deviation percentage, stressing date, operator name, and any re-stress actions. When the special inspector arrives, the complete stressing record is available in seconds.
PT Material and Strand Tracking Per Slab
POD tracks strand usage, anchorage hardware, and grout volumes against the material budget for each slab. Overages and shortages surface before they become change orders. The material reconciliation dashboard shows budgeted vs. committed vs. spent across every PT component.
Watch Every Tendon Stress in Real Time
POD tracks the jacking sequence tendon-by-tendon. Elongation readings appear at each anchor as stressing completes. Out-of-tolerance deviations are flagged instantly.
Post-Tension Metrics — Elongation-Verified
Every tendon, every elongation reading, every material delivery feeds these dashboards automatically. Progress tracked against schedule. Materials tracked against budget.
Progress Overview
Material Budget
Built for Post-Tension Slab Documentation
Voice-First Stressing Data Capture
Speak tendon ID, gauge pressure, and elongation measurements directly at the jacking location. POD transcribes, structures, and stores every reading with zero paper and zero typing.
Automatic Tolerance Verification
Each elongation reading is compared to the theoretical value from PT shop drawings. Deviations outside ACI 318 limits trigger immediate alerts to operator, superintendent, and engineer of record.
Jacking Sequence Tracker
Visual dashboard shows every tendon in the slab with stressing status: complete, in-progress, not started, or flagged. The sequence follows the approved stressing pattern from the PT engineer.
Per-Tendon Audit Trail
Complete record for every strand: initial stress, seating loss, final lock-off, measured vs. theoretical elongation, re-stress history, and operator identification. Exportable for inspection packages and project closeout.
ACI 318 Compliance Summaries
One-click compliance reports showing all tendons by slab, deviation distribution, flagged tendons requiring engineering review, and overall pass rate against Section 26.10 requirements.
“We stress 40 tendons per floor on a 12-story parking structure. Before POD, the stressing log was three pages of handwriting that nobody could read by the time the engineer reviewed them. Now every elongation reading is voice-logged at the jack, the deviation calculation is instant, and we caught two out-of-tolerance tendons before the crew moved on. We have not had a single re-inspection request in six months.”
