Every contractor and every factory started QA on paper or in Excel. That is not a failure. A printed checklist and a spreadsheet with a tab per job are the cheapest QA system there is, and for a lot of work they are enough. The question is when they stop being a record you can put in front of someone who is holding your money.
They cost nothing. Excel is already on every office computer, and a printed ITP costs what the printer costs.
They bend to the job. A new client wants a different column or sign-off box, and you add it in five minutes.
Everyone knows how to use them. A leading hand can fill in a paper checklist with no login and no induction. An Excel file that has run the bed set-ups for years is how the yard thinks.
And they do not go down. Paper works in the rain and in a shed with no signal.
If the record only ever has to satisfy the person who made it, this is a hard system to beat.
The trouble starts when the record has to satisfy someone else: the Nominated Authority assessing a claim, or a client querying a panel two years after it left the yard. The checklist becomes evidence, and paper and Excel were not built to be evidence.
Nothing on the sheet proves when it was done. Initials carry no timestamp. A cell going from orange to green says the status changed, not who changed it or when.
The site copy and the office copy drift. The foreman marks up the printed sheet. The office types it into the spreadsheet on Thursday. Within a month there are two records and no way to say which one is true.
It gets filled in from memory. In a CONQA survey of Civil Contractors Federation members, 86% of engineers and supervisors said they spend five hours a week or more on QA and ITP admin. Some of that is sheets completed at the end of the week, back in the office, off a camera roll. The work was probably fine. The record of it is a reconstruction.
The photos live somewhere else. On a phone or in a WhatsApp thread, not on the check they belong to, and six months later nobody can say which trench they show.
Nothing ties the checklist to the lot or the unit. A job folder of PDFs has no per-lot or per-element record, so a question about one panel means searching.
Hold points are a phone call. The sheet marks the hold point and nothing stops the next step. The release lives in someone's inbox.
Claim time means rebuilding. Where the claim is QA-gated, someone pulls the sheets and photos back into the shape the claim needs, and the claim waits while they do.
The record belongs to the person, not the business. The spreadsheet lives with whoever built it. When they leave, it goes with them, or it stays and nobody can read it.
There is no trail when something goes wrong. An NCR or a dispute needs the sequence: who checked what, when, and what happened next. Paper and Excel hold the final state only.
| Criterion | Paper and Excel | Construction QA software (CONQA) |
|---|---|---|
| Cost | Free, or already paid for | Flat subscription from $899/month (manufacturers) or $1,199/month (civil). No per-user charge |
| Setup time | Minutes. Copy last job's sheet | Set up once by our team around your existing ITPs and sign-off chain, then reused job to job |
| Offline on site | Paper always. Excel on a laptop, not in the trench | Captured on the phone with no coverage, syncs when signal returns |
| Timestamps and sign-off | Hand-written initials and a date. No proof of when | Named user, device timestamp, sequence recorded |
| Link to lot or unit | A tab or folder per job. Per-lot only if someone maintains it | Every check tied to a specific lot or unit |
| Photos attached to the check | On a phone or in a chat thread, matched later from memory | Taken inside the check, filed against the checkpoint |
| Hold-point control | Written on the sheet. Nothing stops the next step | Release request routed to the Nominated Authority, who releases from their own device. Sequence recorded |
| Claim-ready export | Rebuilt by hand at month-end | Report generated from what was captured |
| Audit trail | Final state only. Edits overwrite | Who did what, when, in what order. Kept |
| Who owns the record | Whoever built the spreadsheet | The business. Exportable in full, yours to keep |
Spreadsheets and paper are still the right call when the job is small: one crew, one supervisor, a client who wants a signed sheet at the end. They are fine when nobody in your chain gates payment on QA evidence, and for a sole trader invoicing on completion with no tender asking what the QA system is. Until someone asks for the pack, the record is not costing you money.
They stop being fine when one of these lands:
The usual trigger is a contract landing that the current setup cannot carry.
CONQA is construction QA software built on proof: the record that shows the work was done right. It replaces the paper checklist and the QA spreadsheet, and only those. Your ERP and your scheduling spreadsheet stay where they are.
The check is completed on a phone or tablet at the work, offline where there is no coverage, with photos and measurements attached to the checkpoint. Every check ties to a lot or unit. Hold points are released by the Nominated Authority from their own device, in sequence, with a trail of who approved what and when. The QA report assembles itself from what was captured, so where the claim is QA-gated the pack exists at month-end without anyone rebuilding it. The handover pack is the same record at close-out, exportable in full and yours to keep.
On the SH1/29 highway upgrade, Downer moved the QA record from paper to CONQA, then took it to every major project.
"Our site teams are focussed on delivering the works to programme and to succeed, we must complete our quality documentation as the work proceeds."
Cameron Hyndman, National Lead for Digital Engineering, Downer
And the claim, when the record was built as the work went in:
"They know exactly how we're tracking and if we're on programme. Our last progress claim was 900 pages long, because it had a copy of every single trench we worked on, with photos and comments attached."
Jeff Wright, Operations Manager, AE Smith
Pricing is a flat subscription from $1,199 a month for civil and infrastructure contractors and $899 a month for manufacturers. No per-user charge, so the whole crew can be on it. No free trial. Get started says plainly who CONQA fits and who it does not.
Bring your worst spreadsheet. We will show you the same checks captured at the work face and assembled into the pack, with no Thursday transcription.
Yes, once the ITP has to be evidence rather than a memory aid. ITP software holds the plan digitally and records each check against it at the work, with photos attached, a timestamp and a named sign-off. The record is made when the work is, tied to the lot or unit, and cannot drift between the site copy and the office copy. See what ITP software has to do.
What is the best alternative to Excel and paper for construction QA?Purpose-built construction QA software that captures the check at the point of work, offline if needed, attaches photos to the checkpoint, signs off hold points with an audit trail and exports a claim-ready record. Judge any option on those things rather than on a feature count. If your money or your liability turns on QA evidence, that is the alternative worth paying for. If it does not, Excel is still fine.
Can I keep my spreadsheets and still use QA software?Yes, and most customers do. CONQA replaces the QA checklist and the QA record, not the production spreadsheet, the scheduling file or the ERP. It sits alongside them as the independent record of the checks, and the data exports in full, so you can still pull it into Excel for your own tracking. Planning stays in your spreadsheet. The QA evidence lives in CONQA.
How much does QA software cost compared with spreadsheets?Spreadsheets cost nothing to run. The cost shows up when the record has to be defended. CONQA is a flat subscription from $1,199 a month for civil and infrastructure contractors and $899 a month for manufacturers, with no per-user charge and no free trial. Weigh that against one held claim line, one afternoon reconstructing a job for a client, or one dispute where the record was not there. Get started has the who-it-fits detail.
