What does site survey software do for construction teams?

It lets site teams log snags, run QA and commissioning checks and record pre-start conditions on a phone, pinned to the plot, level or room on the floor plan. Photos, measurements and video are captured offline, and the snagging register or handover pack is exported from that record instead of being retyped.

Where projects lose time

The site is not the problem.
The paperwork gap is.

The snag list is a photo of a whiteboard. The commissioning sheets are in a folder on someone's laptop. The defect the client raised on Tuesday is halfway up a WhatsApp group. Then, four weeks before handover, somebody has to turn all of that into an O&M pack.

SiteSurvey builds the structured record while the team is already walking the plots, inspecting the risers and commissioning the plant.

01

A photo with no address

Three hundred snag photos in a camera roll and nothing to say which plot, which level or which door frame each one belongs to.

02

Two trades, two formats

One subcontractor sends a marked-up PDF, another sends a spreadsheet. Comparing progress or defending a QA position means reading both by hand.

03

Handover starts from scratch

The commissioning results, inspection sheets and progress records exist, but reassembling them into an O&M pack becomes a job in itself right at the deadline.

One continuous record

From the site walk
to client sign-off.

Capture the information once. Keep its location, evidence and ownership connected all the way through delivery.

01

Walk the level

Photograph the defect, film it with Walk Cam or measure the opening — on the phone already in the site manager's pocket.

02

Pin it to the plot

Attach the snag to Plot 14's en-suite or the Level 2 riser, so nobody has to guess which door the cracked frame was on.

03

Complete the check

Run the fire-stopping inspection, the M&E commissioning sheet or the induction form assigned to that exact space.

04

Issue the pack

Export the snagging register, progress record or handover pack from data already captured — no re-typing it into Word.

Evidence in the field

The detail stays
with the work.

Scan the label on an AHU or a distribution board to capture its serial and IP address, record the test values, film the defect with Walk Cam while voice-to-text writes the note — all against the plot and space it happened in, with or without a signal.

What construction teams use it for

Snagging, handover packs and pre-start surveys.

Snagging and defect close-out, M&E installation and commissioning sign-off, weekly progress records, site inductions and the O&M documentation — the jobs that usually live in separate spreadsheets, camera rolls and WhatsApp threads.

Digital snagging

Log the defect where you find it — photo, severity and the trade responsible — pinned to Plot 22's bathroom rather than buried in a camera roll. Watch open snags close out live and export the register for practical completion.

How digital snagging works →

Handover & O&M packs

Fire-stopping checks, commissioning sheets, serials and sign-off photos are already tied to the room they came from, so the handover and O&M documentation is assembled from the record instead of rebuilt in the last four weeks.

Construction use cases →

Pre-start site surveys

Record the state of the neighbouring wall, the existing floor finish and the access route before anyone starts — structured forms, dated photos and floor-plan context, so a dilapidations claim later has a baseline to answer it.

Construction toolkit

Built around how a site is actually delivered.

Inspections

A checklist per plot, riser or plant room

An apartment gets the pre-handover snag sheet, the riser gets the fire-stopping check, the roof gets the fall-arrest inspection. Rebuild an existing QA sheet as a template, or ask AI to draft the form.

Location

Snags that keep their address

Upload the architect's plan, mark out the rooms and pin each defect where it actually is. "Cracked tile, Block C, Plot 22, bathroom" — not photo IMG_4821.

Walk Cam

Film the defect instead of typing it

Hold to record a short clip at each inspection point while live on-device voice-to-text writes the observation as you speak. Works fully offline, and the transcript lands in the report with the still frames.

Commissioning

Serials, test results and sign-off

Scan a label to capture an asset's serial or IP address, record the test values against the unit, and keep the M&E installation record in the same place as the photo of it in the ceiling void.

Delivery

One live snag list for every trade

Site managers, the client's inspector and each subcontractor look at the same open items — what's closed out, what's rejected and what's ready for practical completion.

Handover

The O&M pack builds itself

Every inspection, commissioning record and photo stays traceable from first fix through to client acceptance, so the handover pack is assembled rather than reconstructed.

Plans become operational

Do not just record the snag.
Show exactly where it is.

Upload the plan, create the spaces and connect each room to its own products, evidence and forms. The record reflects the real site instead of becoming another disconnected list.

Construction FAQ

Construction site surveys: common questions.

Browse all construction FAQs →
01What is construction site survey software?+

Construction site survey software is a mobile app and web portal used to record what is actually happening on a site, in place of paper sheets, camera rolls and spreadsheets. Site teams capture photos, video, measurements, checklist answers and asset details against a specific plot, level or room, and the office receives a structured, timestamped record it can search, report on and hand over. On a construction project it typically covers pre-start condition surveys, progress records, snagging and defect lists, M&E installation and commissioning sign-off, and the evidence that goes into the handover and O&M documentation. The difference from a shared photo folder is location and structure: every observation keeps the space it came from and the form it was captured under, so the record still makes sense at practical completion months later.

02Can snagging and defect lists be captured on site?+

Yes. A defect is logged where it is found — photo, severity, trade responsible and a note — and pinned to the correct plot or space on the floor plan. Open snags stay visible to the site team and the subcontractor until they are closed out, and the full snagging register can be exported for practical completion instead of being retyped from a notebook.

03How is a construction handover pack put together?+

It is assembled as the work happens rather than written afterwards. Because inspections, commissioning records, photos and sign-off forms are already attached to the room or asset they belong to, the handover and O&M documentation is produced from data that already exists. The finished report can be branded and shared with the client without asking them to dig through raw site data.

04Can M&E installation and commissioning be signed off?+

Yes. Products and assets can hold any custom data point — serial number, IP address, circuit reference, pressure or test result — and a label can be scanned to capture the identifier rather than typing it. The commissioning form, the test values and the photograph of the installed unit stay on the same record, in the space it was installed in.

05Can each plot, riser or plant room have its own checklist?+

Yes. Each space carries its own forms, products and data points, so a plant room can follow a different inspection path from an apartment, a corridor or an external area. Existing QA sheets, pre-start surveys and induction forms can be rebuilt as reusable templates with mandatory fields, conditional logic and the question types the process needs.

06Does it work with no signal in a basement or steel frame?+

Yes. Forms, photos, measurements and Walk Cam clips are captured and stored on the device with no connection at all, and sync securely once the phone reaches coverage again. Basements, lift shafts, plant rooms and early-stage frames are the normal case rather than the exception.

07Can a defect be recorded as video instead of typed notes?+

Yes. Walk Cam records a short clip at each inspection point while live voice-to-text writes the observation as it is spoken — useful for water ingress, a run of poor pointing or anything faster shown than described. The clips work fully offline and land in the report alongside their transcripts and still frames.

08Can subcontractors and multiple trades work in the same record?+

Yes. Multiple users work across the same projects and sites, with bookings, progress visibility and a record of who captured each update. Each defect keeps the trade it was assigned to, so responsibility for a snag does not get lost between the main contractor and the package.

09What is the best construction site survey app?+

The best construction site survey app is the one your site team will use on every walk and that keeps each snag, check and photo against the plot or space it belongs to. Look for offline capture, forms you can change yourself, defects pinned to the plan, and a snagging register and handover pack produced from the record. If you need programme scheduling, estimating or design, those are separate tools. SiteSurvey is strong on snagging, commissioning records, Walk Cam video and offline working. It does not schedule the programme or certify the work.

10Who is it for?+

It is for main contractors, site managers, QA and compliance teams, M&E contractors and subcontractors who need one shared record of snags, checks and sign-off from pre-start to handover.

11How much does it cost?+

Pricing is per user, not per project or plot. The Works plan, which includes the custom form builder, floor plans, snagging and reports used on construction sites, is £25 per user per month. The Base plan starts at £13 per user per month. Every plan starts with a trial from £1, cancel any time.
