From dictation to report — see it once.

The problem

Built properly. Documented eventually.

After ten hours on site, nobody types reports anymore. That's exactly where the most expensive gaps appear.

Written too late

The report gets written days later, from memory — patchy and easy to attack in a dispute.

Done, never reported

T&M hours and extra work show up in no report — and are missing from the invoice later.

Free text without a BoQ link

What got done sits somewhere in prose. Matching it to the bill of quantities stays manual labour.

2In the background

The AI structures it — and adds what's missing.

Syntact turns the dictation into a complete report: work is matched to BoQ items, weather data is added automatically, T&M work is detected and split into its own T&M report.

  • The report comes out in your template
  • BoQ import via GAEB DA XML / ÖNORM A 2063
  • Original recording and timestamp are kept as evidence
3Next morning

Review, approve, bill.

The finished report waits for approval — on the phone or in the office. After approval it is transmitted on time; hours and progress flow into your billing.

  • Approval stays with your people: the AI drafts, humans decide
  • Same-day transmission to the client, logged automatically
  • T&M hours end up on the next interim invoice

Day to day

Four situations every site manager knows.

5:30 pm · end of day
The report is already written.

Instead of 45 minutes of evening typing: 3 minutes of talking during the walkthrough. The report sits ready for approval.

45 minutes a day back
3 weeks later
The T&M hours are proven.

The client disputes the hours — but the T&M report was created and transmitted the same day, with timestamp and original recording. If the objection misses the deadline, the report counts as approved.

T&M hours get paid
Monday · steady rain
Bad weather is documented.

Weather data is part of every report automatically. The basis for an extension of time is there before anyone asks for it.

Claim backed by data
During the walkthrough
Extra work becomes a change order.

“That wasn't in the tender” — said once, the AI flags the work. The claim is announced within the deadline.

What that means commercially

VOB & ÖNORM — in plain language

Document same-day and you win.

The rulebooks reward fast documentation — free of legalese:

§ 15 VOB/B
T&M sheets: submit daily

Germany's VOB expects T&M time-sheets daily. Returned without objection for 6 working days, they count as approved — the deadline works for you.

14 days
ÖNORM: deemed confirmed

Under Austria's ÖNORM B 2110 a transmitted report counts as confirmed if no written objection arrives within 14 days. Prerequisite: it was transmitted on time.

same-day
Syntact meets the deadlines

Reports and T&M sheets are created the same day and transmitted after approval — with timestamp and log as proof.

In short: same-day documentation is the strongest card in any dispute — and with Syntact it's the default.
The difference

Site diary apps digitise the form. Syntact retires it.

Classic apps move the typing to the phone. Syntact replaces it — and makes the documentation billable.

FAQ

Questions from site managers, owners & IT.

Your question missing? Ask us directly.

Is a site diary mandatory?
The site diary — in the US usually called a construction daily report or daily log — is not required by a general statute; the obligation comes from the contract or the role. For architects and engineers doing site supervision, documenting the construction process is a core duty (HOAI service phase 8 in Germany), and public clients regularly require it in their contract terms. Contractors need daily reports at the latest when progress, disruptions or T&M work must be proven — under the German VOB/B just as under Austria's ÖNORM B 2110.
Who keeps the site diary?
In Germany it's usually the site manager or the supervising architect; in Austria the client-side site supervision (ÖBA) keeps the Baubuch. Contractors keep their own daily site reports — as proof of work performed, crew levels, disruptions and T&M work. Exactly those reports are what Syntact creates from your site managers' dictation.
What belongs in a site diary?
Per working day: date, weather and temperature, companies present and crew strength, plant on site, work performed and progress, deliveries, special events such as disruptions, client instructions, and defects. Photos with timestamps add a lot of evidential weight. Syntact actively asks for missing items during dictation and adds weather data automatically.
Is a digital site diary legally sound?
Yes — there is no prescribed form. What counts is completeness, timeliness and tamper-resistance. A digital diary with automatic timestamps, the original voice recording, weather data and a change history is far more robust in a dispute than a Word file written days later.
What is T&M (Regie) work — and why does it get lost?
Time-and-material work is billed by actual effort instead of unit prices from the bill of quantities — typical for unforeseen extra work. It must be agreed in advance, recorded continuously, and submitted to the client promptly for confirmation. It gets lost because nobody writes down in the evening who did what on T&M. Syntact detects T&M work in the dictation and automatically creates separate T&M reports for sign-off.
Does it cope with dialect and site noise?
Yes. Dictation happens over a Teams call — speech recognition covers German including Austrian and southern German varieties (and English), primed with your project context: trades, BoQ items, company names. In the pilot we prove it with your site managers on your sites, not in a lab.
How is Syntact different from PlanRadar, 123erfasst & co?
Documentation apps digitise the form — Syntact connects the documentation to the money. The daily report is created by voice in Microsoft Teams and automatically linked to your BoQ items and commercial systems: one dictation becomes the site diary, the T&M report and the progress report. Existing tools can stay — Syntact is the platform underneath, not another island app.
How does the target data get from RIB iTWO or AUER into Syntact?
Via data carrier: Syntact imports your contract bill of quantities as GAEB DA XML (e.g. X86) or ÖNORM A 2063 — formats every common AVA and estimating package exports. Direct API connections are possible; missing connectors we build for free.
What about data protection and employee data?
Syntact is operated GDPR-compliant in the EU — on request in your own cloud or on-premises. Personal data such as crew levels stays in your systems, and access follows your permission model. We provide the documentation your DPO and works council will ask for.
What does it cost?
The platform starts at €800 per month — and the license only starts once you're in production. Setup and BoQ connection are included in the pilot package, and the implementation is covered by the 50/50 guarantee. In the demo we'll build the business case with your numbers: a few billed T&M hours per week already carry the license.

The next site day is certain. The question is whether it costs you money.

Three minutes of dictation instead of 45 minutes of evening paperwork — and every T&M hour makes it onto an invoice.
