Executive Summary

  • The Question: Which records should a construction project keep, at which phase, and who should be responsible for each one?
  • The Answer: Keep five streams of records running from the first contract draft to the end of the defects period: contract and commercial, design, field, quality and safety, and handover. Assign each record an owner, a trigger and a single storage location before work starts, and check the register at the end of every phase.
  • The YelloSKYE Angle: Construct IQ adds the dated visual stream to that register, capturing the site with drones, 360° cameras and fixed cameras so the written records have physical evidence beside them on the DEX platform.

A construction documentation checklist lists the records a project must create and keep at each phase, from the signed contract to the end of the defects period, together with the person responsible for each one. Its purpose is simple: when anyone later asks what was agreed, what was built or what was approved, the answer already exists and can be found.

Most projects produce plenty of paperwork. What they lack is a plan for it. Drawings get superseded without the old revision being archived, a site instruction lives only in an email, a test certificate is in the subcontractor's van. This guide sets out the records to keep phase by phase, the owner of each, and how a visual record from Construct IQ, our construction monitoring solution, fits alongside the written ones. If you are mainly interested in site photographs, our construction photo documentation guide covers capture and organisation in detail.

The five streams of project records

It helps to stop thinking of documentation as one pile and treat it as five streams that run in parallel. Each has a different author, a different audience and a different reason to exist.

Stream Typical records Usually created by Relied on by
Contract and commercial Contract, programme, payment claims, variations, notices, correspondence Owner's project manager, contractor's commercial team Owner, lenders, quantity surveyors, lawyers
Design and technical Drawings, specifications, models, requests for information, submittals and approvals Design team, contractor's design coordinator Every trade on site, the owner at handover
Field and progress Daily reports, site instructions, meeting minutes, labour and plant returns, dated visual record Site manager, site engineers Project manager, planners, commercial team
Quality, testing and safety Inspection records, test results, non-conformances, permits to work, incident reports Quality manager, safety manager, specialist testers Owner's representative, authorities, insurers
Handover and operations As-built and record drawings, manuals, warranties, certificates, asset registers Contractor, with input from every trade Owner, facility manager, future designers

When a dispute or a question arises, it usually needs records from more than one stream. A variation claim, for example, draws on the contract (what was the original scope), design (which revision changed it), field (when the work happened) and commercial (what was paid). If one stream is thin, the others cannot make up for it.

How to set up the register before work starts

A checklist only works if it is turned into a register at mobilisation, not assembled at the end. For every record type, agree four things.

Write these into the project execution plan and share them with every trade at the start. Subcontractors are far more likely to hand over test certificates and mark-ups on time if they know from the first week that payment depends on it.

Phase 1: Before mobilisation

This phase fixes the starting point. Almost every later argument about scope, quantities or damage is measured against what was recorded here.

Contract and commercial

Design and approvals

Site baseline

Phase 2: Mobilisation and early works

The site is now live, and the routine records begin. The habits set in these first weeks decide whether the register stays complete.

Phase 3: Structure and envelope

This is the phase where most of the building disappears from view. The records you need are those that prove what is inside the concrete, behind the cladding and under the roof finish.

Phase 4: Services, fit-out and commissioning

As the building closes in, the volume of records rises sharply because many trades work in the same spaces.

Phase 5: Completion and handover

Handover documents are only as good as the records gathered in the earlier phases. If the register has been kept up, this phase is a matter of checking and compiling. If it has not, it becomes a search.

In our warehouse operator handover use case, the developer gave the incoming operator role-based access on the DEX platform to the full visual history of the build, and reported zero post-handover documentation disputes.

Phase 6: The defects period and beyond

Documentation does not stop at the handover meeting. During the defects period, keep a log of every defect reported, when it was reported, the repair carried out and when it was accepted. Record the condition of each repair, because a recurring defect is often a sign of a deeper problem that was hidden at handover.

After the defects period ends, archive the complete register in a form the owner can still open in ten or twenty years. Proprietary file formats, personal accounts and expired software licences are the usual reasons old project records become unreadable.

Where the visual record fits

Written records describe what someone decided or observed. A dated visual record shows the physical condition that existed at a moment. The two are strongest together: a daily report that says a membrane was laid on level 2 means far more when it links to images of level 2 taken that day.

Construct IQ combines drone surveys, 360° interior walks and fixed cameras, and the DEX platform keeps every capture on one timeline, so a reviewer can scroll back through site history day by day. Issues can be tagged directly on the site visual at the point they refer to, and DEX integrates with Procore, Autodesk BIM 360 and ACC, so the visual record can sit alongside the document system rather than in a separate silo. Fixed cameras add a continuous view of selected zones between scheduled captures, which fills the gaps a weekly or monthly rhythm leaves.

For a closer look at how these records are tested when a disagreement arises, see our guide to construction dispute documentation.

Keeping the register under control

Four habits prevent most documentation failures.

Control revisions

Every drawing and specification needs a revision status, and superseded versions must be archived, not deleted. When a question arises about why something was built a certain way, the answer is often in the revision that was current at the time.

Number everything that changes scope

Site instructions, requests for information and variations should each carry a unique number from a single sequence. Unnumbered instructions are the ones that go missing.

Keep one master copy

Decide which system holds the master version of each record type and say so in writing. Copies in email, chat and personal folders can exist, but nobody should have to guess which is current.

Review at phase gates

At the end of each phase, check the register against this checklist before the next phase starts. Gaps found while the work is still visible can be filled. Gaps found at handover usually cannot.

Construction documentation checklist

Use this as a phase-gate review. Each line should have an owner and a storage location in your register.

Before mobilisation

  1. Signed contract, appendices, baseline programme and bill of quantities saved as fixed versions.
  2. Drawing register, approvals and their conditions, and site investigation reports filed.
  3. Baseline survey of the site and condition record of neighbouring property completed.

Mobilisation and early works 4. Daily reports, site instructions and requests for information running, numbered and dated. 5. Formation levels, ground conditions and buried services recorded before backfill. 6. Inductions, permits to work and safety inspections logged.

Structure and envelope 7. Pour releases, concrete tests and reinforcement checks filed against each element. 8. Envelope fixings, membranes and openings recorded before they are covered. 9. A site-wide capture taken at every payment cut-off.

Services, fit-out and commissioning 10. Services, fire stopping and tests recorded room by room before closing in. 11. Submittals, variations and commissioning results linked to their locations and systems.

Handover and after 12. As-built mark-ups collected and record drawings issued. 13. Manuals, warranties, certificates and the closed punch list compiled. 14. Visual archive transferred to the owner with controlled access. 15. Defects log kept to the end of the defects period, then the full register archived in open formats.

Frequently asked questions

What documents are needed for a construction project?

Every project needs contract and commercial records (the contract, programme, payment claims and variations), design records (drawings, specifications and their revisions), field records (daily reports, site instructions and a dated visual record), quality and safety records (inspections, tests and incident reports), and handover records (as-built drawings, manuals, warranties and certificates). The exact list grows with project size, but those five groups apply everywhere.

Who is responsible for construction documentation?

Responsibility is split by record. The main contractor usually keeps the field, quality and safety records, the design team controls drawings and specifications, and the owner's project manager keeps the contract and payment records. Problems start when nobody owns the register as a whole, so name one person to check it is complete at the end of each phase.

What is the difference between as-built drawings and record drawings?

As-built drawings are the marked-up working set that shows where the finished work differs from the design, usually kept by the contractor during construction. Record drawings are the clean, formal set the design team produces from those mark-ups at the end of the project for the owner to keep. Both depend on changes being logged as they happen.

How long should construction records be kept?

Keep them at least until the defects period has ended and for as long as a claim could still be brought under your contract and the applicable law, which can be many years after completion. Owners often keep handover records for the life of the building. Confirm the period with your legal adviser; this guide is general guidance, not legal advice.

Can digital records replace paper construction documents?

In most cases, yes, provided the system keeps original files, records who created or changed each item and when, and controls who can edit what. Signed certificates and some statutory approvals may still need a particular format, so check what each authority and your contract require before discarding paper originals.
