The field system & provenance registry for salvaged timber
Hewmark keeps the whole story of a structure — from the first tag you strike in the field to the certificate your buyer scans. Map the teardown beam by beam. Guide the rebuild — scan a timber and see exactly where it goes. Prove the provenance with a signed history no one can quietly rewrite. All of it from the phone in your pocket.
One system, yard to rebuild
Three pieces that share one record — what you capture in the field is what guides the rebuild and what backs the sale.
Tag every member and Hewmark maps it to its exact place — wall, course, position — in a working model of the structure.
Every field entry is signed on your device and chained to the one before. Append-only: nothing edited, only added — with who and when.
The record you built becomes the paperwork your buyers already ask for — without a week at a desk.
Hewmark Field — the digital twin
Struck in place. Every tag records more than the timber — it records the slot: wall, course, position. Strike tags as you work and the structure becomes a model you can explode, rotate, and inspect, built from nothing fancier than the phone in your pocket.
Sequenced like the real thing. The twin knows what rests on what — which members can come down next, which have to go back first. The teardown order and the rebuild order stop living in one person's head.
Scan a beam, find its home. In a stack of two hundred look-alike timbers, scan one tag and the model shows its exact slot — and whether it can be placed yet.
The map outlives the building. Fire, storm, or ten years in the queue: as long as the twin exists, the structure can be put back. That's the file insurers and heritage reviewers actually want.
The way it works today
Chalk on the beam, a sketch in a spiral pad, photos lost in a camera roll. If the notebook gets wet — or the one guy who gets it retires — the building's map is gone.
New lumber, distressed and sold with an invented history, trades on the reputation honest dealers spent decades building. Buyers can't tell the difference — and the premium erodes for everyone.
Architects chasing LEED credits, insurers underwriting a reclaimed-timber great room, appraisers building a file — they all need documentation. Today they get letterhead.
How it works
No new hardware. No back-office software. It works in the yard, with gloves on, without a signal.
Tag the beam, scan it, and capture what's true — photos, measurements, species, and its exact slot in the structure. Sticky defaults make a fifty-beam lot an afternoon.
Every entry is signed by a key that never leaves your device and chained to the entry before it. Append-only: nothing edited later, only added — with who and when.
At the new site, scan any timber and the model shows where it goes and whether it can be placed yet. The dismantle map becomes the assembly manual.
Selling instead of rebuilding? The certificate prints with a QR. Your buyer scans it and verification runs in their browser — every signature, the whole chain.
Why "Hewmark"
In the river-drive days, every log that went downstream carried its owner's registered mark, struck into the end grain with a stamp hammer. The county kept the book of marks — a public registry of timber provenance, a century and a half before anyone said "database."
Hewmark is that book, reborn: a mark for every hewn beam, and a registry anyone can check.— the whole idea, in one sentence
Who it's for
Map the teardown, certify the lot, and put a verifiable history behind your premium. Protect your name from the fakes trading on it.
Every member mapped to wall, course, and position — with rebuild sequencing that knows what has to go in first. The notebook, retired.
Member-level, independently verifiable documentation — species, dimensions, source, custody — that supports LEED submissions and survives underwriting.
Straight talk
A trust product that overclaims isn't one. Here is the whole deal, plainly.
A signature proves who said it, not that it's true. What changes is that lying becomes expensive, permanent, and attributable — and certification requires documentation minimums (multiple photos, full measurements, species, source attestation) before we'll issue it. Fakers don't sign their names to things.
Pricing
One certified lot costs about one percent of one beam's premium. You do the math — your buyers will.
Full dismantle-and-rebuild projects (Hewmark Field, end to end) are priced per structure — tell us about the building. High-volume yard plans arrive when the first crews outgrow per-lot.
Questions crews actually ask
Yes — that's Hewmark Field. Every tag maps a timber to its exact slot: wall, course, position. During reassembly you scan any beam and the model shows where it goes and whether it can be placed yet, based on what has to go in beneath it first. The record you build tearing down is the manual for putting back up — and it's the same record that becomes the certificate if you sell instead.
Yes, and no scanner. The twin is built from your tags: every timber you strike gets a slot — wall, course, position — and the model assembles itself from those records. It's not a laser scan; it's something more useful for this work: a model that knows where every member belongs, what it rests on, and what order things come apart and go back together. Phone only, gloves on, no signal required.
Your repeat customers do. The certificate is for the architect who's never met you, the appraiser who needs a file, and the buyer comparing your beam to a cheaper one with an identical story. It converts the strangers — and protects your reputation from the fakes trading on it.
FSC chain-of-custody certifies your operation, once a year, for thousands of dollars — it was built for mills. Hewmark certifies each beam, for about a dollar, today, from your phone, and your buyer can check it themselves. Plenty of dealers will treat them as complementary: FSC for the operation, Hewmark for the inventory.
It's a QR code on a tag. Your buyer scans it with their camera — that's the whole experience. Under the hood we use the same signature math your bank uses, and no, there's no coin, no token, and nothing to invest in.
A signature proves who said it, not that it's true. What changes is that every claim is attributable, photo-hashed, timestamped, and impossible to quietly revise. Certification also requires documentation minimums — multiple distinct photos, complete measurements, species, source attestation. Lying becomes expensive, permanent, and signed with your own name. That's a bad business to be in.
Your signing key comes with a recovery phrase you write down at setup. New phone, same identity, history intact. (And your certificates never depend on your phone — they live in the registry.)
Nothing. Verify pages stay live forever, and you can export your complete history any time. A trust product that holds your provenance hostage isn't one.
