The field app · unlimited users · 14-day trial

Your paperwork, finished before anyone
leaves site.

The app gives every engineer, operative and supervisor the part of the system they need, and nothing else. Captured where the work happens, in the office the moment they are saved. It goes out under your name and icon on the App Store and Google Play, with the app and its publishing included in the one monthly fee.

Site operative using the Unibuild field app on a construction site

In plain terms

A field app is the part of the system that lives on the operative’s phone: hours, certificates, permits, photographs and signatures, captured where the work is. Unibuild’s is for UK trades and contractors of 5 to 300 people. Unlimited users, one monthly figure, a 14-day trial and no card.

What it replaces

Every one of these is a record
made away from the work.

Not one of them is a person who did not care. They are all the same problem: the paperwork happens somewhere other than where the job did.

Monday morning

Hours arrive as a message saying same as last week. Nobody can prove what time anyone arrived.

Unevidenced

In the van

The gas record is on a carbonised pad. The top copy goes to the tenant, the rest goes in the glovebox.

Chased for a fortnight

The camera roll

Progress photographs live on a personal phone. That phone left the company in March.

Evidence gone

Half past seven

A purchase request is a phone call to somebody who is driving. The van waits at the counter.

Forty minutes

The site office

Permits are a pad of triplicate forms. Half are unsigned and the dates are scribbles.

Indefensible

Anywhere

Nobody in the office knows which phone is on which app version, or who granted camera access.

What is on the phone

Seven things that decide whether
an app gets used or ignored.

25+ modules,
granted per person

Access

The home screen is built from your database, not ours. Tick the modules a given engineer needs on their user record and their phone reflects it next time they open it.

No new app release required
App access is a separate list from web access
A supervisor can have a rich phone and a narrow desk
47 distinct app access patterns in live use

Nobody sees all of itLive

Clock in by scanning
the site poster

Hours

Print the project poster, put it on the welfare unit door. Scanning it records the project, the clock-in time, the operative's location and a photograph. What that scan proves is set out in QR codes on construction sites.

The time is recorded at the scan, not read from the phone
It cannot be back dated by changing a phone clock
Projects can be set so QR is the only way in
3,421 of 5,204 clock-ins carry a photograph

Attendance as evidenceLive

Signed on the phone,
before he drives away

Sign

Gas safety records, engineer's reports, day work sheets, call-outs, permits, toolbox talks and store collections all take signatures on the screen.

The signatory's printed name and the date against it
Drawn straight into the generated document
More than thirty forms capture one
A signed day works sheet is a paid day works sheet

Agreement where the work wasLive

Planner

Site operatives open the project planner on the app and see the programme, what is scheduled, where they are needed and the detail of the job they are on, rather than ringing the office to ask.

The planner, not a screenshot of it
Progress visible to the client in their own portal
Drawings, documents and records against the project

Nobody rings to ask what is onLive

Approvals in
your pocket

Decide

One Alerts module carries six queues with a live count that is calculated for the individual, so the badge shows work you actually have authority over, from purchase order approval on the phone to a holiday request.

The notification opens the approval screen itself
Purchase orders, timesheets, holidays, agency workers
Reject with a written reason that reaches the requester
A director clears a queue between site visits

Minutes, not daysLive

Scan a tool, see
its test history

Assets

Every asset carries its own unique QR label, branded to your firm and sized for a desktop label printer. Scan it and the phone shows the test record, the service history and the attachments. Photographs, video and documents attach to a service record from the phone as the work is done.

Class, fuse, insulation, leakage, polarity, pass or fail
Maintained assets return their PPM and SFG20 schedules
Fire assets return their inspection records
Nobody uses a tool that is out of date

The record travels with the itemLive

Support

One page lists every handset, the version it is running, the model, when it was last used and whether notifications are switched on.

Each user's record shows which permissions their phone granted
A photograph that never arrives takes two minutes to explain
Deactivating a user revokes every device session at once

The only question that matters

Will your engineers
actually use it?

Every contractor asks this, and most software companies answer it with adjectives. Here is the mechanical answer instead.

They will use four or five screens and ignore the rest: Which is exactly why the app only shows them the modules you have granted. An engineer with six modules on his home screen is looking at a tool. An engineer with all 25+ is looking at a system, and he will not open it twice.
The app is how they get paid: This is the whole mechanism, and it is not a design flourish. Clocking in and recording hours is the reason to open it, every day, without anybody asking. Everything else in the app is then already in a place they are used to going.
Login is a four digit PIN: Not a password with a capital letter and a symbol, typed with gloves on, at seven in the morning, in the rain. The PIN also makes a shared site tablet usable by several people who each sign as themselves rather than staying logged in as whoever set it up.
The evidence, rather than the promise: 5,204 clock-in records and 6,643 timesheet entries in one deployment alone, every clock-in from an operative scanning a printed code. 4,237 of those entries came from a scan rather than a keyboard. 200 of 244 fire door inspection records were raised on the phone, and 242 of them carry a signature drawn on the screen.
What adoption needs from you: Adoption does not happen by itself. It needs supervisors to expect it for the first fortnight, and it needs the paper route closed rather than left running alongside. We help you plan that. The platform helps too: the office can see which handsets have actually granted notification permission, so "I never got the alert" becomes a two minute diagnosis rather than an argument.

Running it across a fleet of phones

Adding a module does not
mean updating every handset.

01Each phone gets what it can run: Every request the app makes carries the version it is running, and modules that need a newer build are simply not offered to older ones. That is how the construction deployment has added modules over several years without a coordinated fleet wide update. Where a release genuinely must be adopted, a required update message can be switched on.
02Agency labour onboarded at the gate: A temporary worker registers on his own phone at seven in the morning: name, contact, PIN, card number, card expiry and photographs of both sides of the card. He cannot log in at all until somebody with authority approves him, and that approval is stamped on the record with a name and a time. When a main contractor asks who checked the card, there is an answer.
03Leavers, immediately: Deactivating a user revokes every device session they hold in the same operation, so the app on their phone stops being authorised on its next call rather than continuing on a cached session. A single device can also be signed out on its own, which is what you want when a phone is lost rather than a person.
04Training that never touches live: The platform can run a sandbox that mirrors the live database, so a new starter or a new release is exercised on realistic data, in the same screens, with the same permissions, and nothing anyone does reaches a real order, a real client or a real account. The usual reason staff avoid part of a new system is that the only place to practise is the live one.

It has always been a pleasure to work with Darshan and his team to create our completely bespoke system, which I can only describe as brilliant.

The system is constantly growing and improving. Whenever we need something added or changed, whether it's a new form that would work better for us or a new idea to improve the way we work, Darshan works his magic and makes it happen!

It has genuinely changed the way we work for the better, improving our record-keeping, automating processes and standardising practices across the company, saving us both time and money.

It's also improved the service we provide to our clients, who love being able to view their job and asset information live, at the click of a button.

Thank you, Unibuild!

Questions

Asked by the person who
has to roll it out.

Is this a site app for trades?

Yes. It is the field half of Unibuild for UK trades and specialist contractors: 25+ modules on the operative’s phone, granted per person. They run from QR clock-in and timesheets to gas records, permits, RAMS signing, call-outs and approvals, and it is published under your name on the App Store and Google Play.

What does it cost?

One monthly figure, quoted in writing, fixed for three years, unlimited users. No per-user charge, so every operative, apprentice and subcontractor on the app is included, and so is publishing it under your name on both stores.

Is there a free trial?

Yes, 14 days of the full platform, no card, on your real sites with your real people. A sandbox with your project names in it is set up first, so nobody judges the app on somebody else’s data.

How long does it take to go live?

Most firms go live in about two weeks, in phases. Because modules are granted per person, a crew can start with clock-in and timesheets and have the rest switched on as each phase lands.

Will our engineers actually use it?

Yes, because the app is how they get paid. Clocking in is the reason to open it every day, so everything else is already in a place they go. Each person only sees the modules granted to them, from 25+, so an engineer with six on the home screen is looking at a tool. Login is a four-digit PIN. In one deployment, 4,237 timesheet lines came from a scan rather than a keyboard.

Is the app branded as Unibuild, or as us?

As you. Your staff app is published under your company name and icon on the App Store and Google Play, and the office portal carries your name, logo and colours. An operative searches the store for the firm on their payslip and finds it. The app and its publishing on both stores are included in the one monthly fee. How your own branded app works.

Does the app work on sites with no signal?

Yes. The app works online and offline. On a site with no signal, clock-ins are stored on the phone and synced with the office the moment it is back in signal. The rest of the day’s work syncs the same way. Basements, plant rooms, prisons and rural sites are recorded as reliably as a site with full coverage, and nobody re-enters anything afterwards.

Can drivers do their daily vehicle check in the app?

Yes. The daily driver vehicle check is done in the app before the vehicle is used, with any defect logged with photographs and video. It lands on its own tab in the office portal, against the vehicle and the driver. Reminders for MOT, road tax, insurance and service arrive as push notifications too. Vehicles and fleet.

Can site workers buy small items and claim them back in the app?

Yes. The worker raises a purchase request in the app, the office approves it from a push notification, and after buying, a photograph of the receipt becomes the reimbursement claim. The firm sets a spending limit, and the worker is notified as the claim is processed. Site purchases and reimbursements.

Can engineers report an Awaab’s Law hazard from the app?

Yes. An engineer who finds a potential hazard in a social rented home reports it in the app at the property, on any visit, with as many photographs as it needs. Submitting it alerts the office at once, and the engineer sees on the phone when the office has picked it up. What they type is kept on the phone until the report is sent. See Awaab’s Law hazard reporting.

Can documents be signed on the phone before the engineer leaves site?

Yes. Gas safety records, engineer’s reports, day works sheets, call-outs, permits, toolbox talks and store collections all take a signature on the screen. More than thirty forms capture one, with the signatory’s printed name and the date, drawn straight into the generated document. In one deployment, 242 of 244 fire door inspection records carry a signature drawn on the screen.

Can purchase orders, invoices and expenses be handled in the app?

Yes. Staff raise purchase orders, record deliveries, and claim expenses and mileage. Approvers approve orders, invoices and expense claims from a push notification, and payment updates appear in the app. It runs on phones and tablets, including an iPad in landscape, and staff sign in with Microsoft or Google.

What happens when someone leaves, or loses their phone?

Deactivating the user signs them out of every phone they use, immediately. A single phone can also be signed out on its own from the user’s record, which is what you want when a phone is lost rather than a person. The office sees every handset in use, its model and when it was last used.

What about agency and subcontract workers?

An agency worker registers on their own phone at seven in the morning, with their card number, its expiry and photographs of both sides. They cannot log in until somebody with authority approves them, and the approval is stamped with a name and a time. Workers without the app still sign a RAMS through its own signing link, which opens in any browser. How RAMS signing works.

We already have a timesheet app. Why change?

Because the hours are only one record made on site. A timesheet app does not know what a day works sheet is, and it does not produce a gas safety record. It does not route a purchase order for approval or put the photograph on the project. Unibuild’s app is one login covering all of it, on the same records as the office system.

Do we have to update every phone at once when you release something?

No. The app tells the platform which version it is running, and modules that need a newer build are simply not offered to older ones. That is how one deployment has added modules over several years without updating every phone at once. When a release must be adopted, a required update message can be switched on.

Is it one app or two? Our clients would need one as well.

Two. Your staff get a field app with 25+ modules. Your clients get a separate seventeen-module app with its own menu and access rules, covering their projects, photographs, documents, asset registers and certificates. A client account never sees a staff screen. Both carry your branding, and the client app is optional and included in the same fee when you want it.

Can we train people before they touch our live records?

Yes. A sandbox mirrors the live system, so new starters are trained and releases are checked on realistic data without a single live record being touched. Staff avoid part of a new system when the only place to practise is the real one, so this matters more than it sounds.

What happens to the paperwork we already have?

Historical certificates, records and photographs are brought across during implementation and attached to the right projects and assets, so the app does not start from an empty register. Migration is included in the fee, and its scope is agreed up front so go-live stays on programme.
