// Modular Buildings

Run your fleet of offices and classrooms
without the back-office pile-up.

Modular building and mobile office trailer rental is a logistics business with a compliance job on top. FieldTracer is the AI Harness that tracks every unit, every permit, every set inspection, and every renewal date — so your team runs the fleet, not the spreadsheets. Harness your operation.

// The real problems

You know the job. The job is managing
what nobody built software for.

Talk to any modular rental operator and the same three problems come up, every time. FieldTracer was built to close all three.

// Pain point 01

Permit expiry slips through the cracks

Every set has an AHJ building permit number, an expiry date, and a post-installation inspection status. When that lives in a spreadsheet, someone finds out the permit lapsed after the customer calls. FieldTracer tracks permit number, expiry, and set inspection status per unit and surfaces renewals automatically — the way you'd want your best dispatcher to do it.

// Pain point 02

No single view of the fleet

Which unit is a 2-section double-wide? Which ones need an ADA ramp at the new site? What's the wind zone on the Durham set and how many anchors are down? FieldTracer keeps the full asset record — building type, size, section count, wind zone, anchor count, ADA access type, electrical service — attached to every unit and every work order.

// Pain point 03

Lease rollovers you never see coming

A 12-month minimum term rolls over and nobody followed up. The unit stays on-site at the old rate, or worse, gets pulled without an extension in place. FieldTracer watches every lease term, flags units approaching rollover without a signed extension, and queues the follow-up before the window closes.

// How it works

From yard to jobsite to invoice —
one harness runs the whole thing.

FieldTracer connects your asset records, dispatch, compliance calendar, and billing in one place. Untrained staff can run it from day one. No extra software to learn, no manual hand-offs between systems.

01

Asset record, always current

Every unit gets a live record: building type, size (e.g. 12x60), floor area, section count, office count, max occupancy, HVAC and plumbing status, electrical service amps. Pre-delivery condition and inspection date are logged before the truck rolls — your damage baseline is locked in before the unit leaves the yard.

02

Compliance calendar that runs itself

Permit number, permit expiry date, set inspection date and status — tracked per unit per set. FieldTracer's Routines watch the compliance calendar and fire alerts before a permit lapses or an inspection hold blocks occupancy. Wind zone, anchor count, and ADA access type are re-recorded on every relocation, so the record always reflects the current set.

03

Dispatch with the right crew and gear

Multi-section units need the right truck and crew. FieldTracer uses section count to flag crew and equipment requirements on dispatch work orders. Setup crew is assigned per set for warranty and liability tracking. Just tell FieldTracer what you need — the way you'd tell your dispatcher — and it builds the work order.

04

Billing that matches the contract

Monthly rate and minimum lease term are on the unit record. FieldTracer auto-calculates term-end alert dates, flags units approaching rollover without a signed extension, and keeps delivery date and removal date in sync with billing cycles. No more calling the customer after the fact to explain a gap.

05

Preventive maintenance on schedule

Roof seals, HVAC filters, electrical checks — last PM date and next service due date sit on every unit record and feed the maintenance dispatch queue. FieldTracer tells your team which units are overdue before a customer call does.

// No training required

Your staff runs it from day one.
No manual. No classroom.

FieldTracer is the AI Harness layered over your operation. Untrained office staff can place orders, log permit numbers, update inspection status, and trigger dispatch — just by describing what they need. The harness figures out the workflow. Your people stay focused on the customer.

// Reception

Order entry by voice or chat

New rental request comes in by phone or web widget. Reception captures it, confirms site address, unit type, occupancy need, and ADA requirements — and hands a clean order to dispatch. No form training, no dropped fields.

// Dispatch

The dispatcher that never sleeps

Set instructions, crew assignment, electrical and plumbing requirements, wind zone check — dispatch work orders are built and routed automatically. Your driver has everything on their phone before they leave the yard.

// Billing

The back-office that never clocks out

Monthly invoices, lease-term renewals, permit renewal flags, PM service billing — FieldTracer's Routines run the billing calendar so nothing slips. Export, print, or push to your accounting system automatically.

// Compliance

Audit-ready, always

Every permit number, inspection date, anchor count, and condition rating is logged with a timestamp. If an AHJ inspector or a lease-end dispute comes up, you have the full record — not a missing spreadsheet row.
