JBCC Site Records — Why They Matter and How to Keep Them Digitally
South African contractors under JBCC contracts are required to maintain contemporaneous
site records. SnapStrux makes this fast enough to do on every site visit.
The Joint Building Contracts Committee (JBCC) publishes the most widely
used standard form construction contracts in South Africa. The JBCC Principal Building
Agreement (PBA), Minor Works Agreement (MWA), and related sub-contract forms govern
the majority of formal building projects in the country.
JBCC contracts create specific obligations for record-keeping. A contractor who complies
with these obligations has a significant commercial advantage in any dispute. A contractor
who does not is routinely exposed to:
Disputed variations — uninstructed work that cannot be proved was instructed
Rejected dayworks — hours and materials that cannot be supported by a contemporaneous record
Unfair delay claims — employer-caused delays that cannot be evidenced with a site diary and timestamp
Lost retention — defects attributed to the contractor that were pre-existing or caused by others
Weak adjudication claims — an adjudicator cannot award what the claiming party cannot prove
The contract does not protect you. Your site record does.
A JBCC contract gives every contractor the right to a variation order for additional work. But enforcing that right requires a contemporaneous record that proves the instruction was given, when it was given, and what was done in response.
Required records
What Site Records Should a JBCC Contractor Keep?
The following records are either explicitly required under the JBCC PBA or are necessary
to enforce rights under the contract. This is a practical guide — not legal advice.
Record Type
Purpose
Critical Detail
Site Instruction Register
Track all SIs by number, issuer, date, and status
Flag SIs not converted to VOs — these are disputes waiting to happen
Dayworks Records
Daily log of hours, plant, and materials for varied work
Must be presented to the principal agent for signature daily or weekly
Variation Order Register
Track all VOs issued, value, and payment status
Link each VO to the originating SI and any supporting photos
Site Diary
Daily record of weather, attendance, events, and access
Contemporaneous — written the day it happens, not reconstructed
Delay Register
Log of delay events with cause, duration, and any notices
JBCC Clause 23 requires notices within specific timeframes
Photographic Record
Before and after photos of work being covered
Critical for foundations, waterproofing, services, and concealed work
Defect List (Snag List)
Record of defects at practical completion
Must be formally issued and tracked through the defects liability period
Site instructions
Site Instructions — The Most Disputed Records in South African Construction
A Site Instruction (SI) under JBCC is a formal written direction from
the principal agent to the contractor. SIs direct the contractor to perform additional
work, varied work, or to address a specific issue on site.
The problem is that many SIs in South African construction are issued verbally, via WhatsApp,
or informally on site — without the contractor recording them properly. When the contractor
performs work in response to a verbal SI and then bills for a variation, the dispute begins.
The correct workflow for every SI:
Record the SI on site immediately — number, issuer name, date and time, description
Photograph any accompanying sketch, written note, or site condition referenced
Flag whether a VO has been issued, is pending, or was not issued
Photograph the work performed in response before it is covered
Keep the SI register updated — if the PA denies the instruction, you have the timestamped record
SnapStrux allows site teams to log site instructions as categorised observations with
photos, timestamps, and GPS — creating an immediately defensible record from the moment
the instruction is received.
Dayworks
Dayworks Records — Photograph Before You Leave Site
Dayworks are one of the most contested items in South African construction contracts.
A dayworks record must show the labour, plant, and materials employed on a specific
activity each day, signed by the principal agent's representative.
In practice, getting a signature on a dayworks sheet every day is difficult. The
site agent is busy, the PA representative visits infrequently, and by the end of the
month the contractor is presenting unsigned dayworks sheets for payment.
The minimum viable dayworks record:
Complete the dayworks sheet daily — do not batch at the end of the week
Photograph the completed sheet at the end of each day, whether or not it is signed
Photograph the workers and plant on site that day as corroborating evidence
Record the specific activity being claimed as a daywork — link it to the originating SI
Note any refusal to sign, and document it as a site observation
A dated photograph of a completed (unsigned) dayworks sheet, taken on site, is stronger
evidence than a sheet completed a month later from memory. SnapStrux timestamps every
capture automatically.
Practical completion
Practical Completion Records Under JBCC
Practical completion under the JBCC PBA is the point at which the works
are complete, except for minor defects that do not prevent the employer from taking
occupation. The principal agent issues a Practical Completion Certificate (PCC) once
satisfied.
The practical completion process generates several critical record-keeping requirements:
Pre-inspection snag list — the contractor should identify and document their own punch list before the PA inspection, establishing which defects existed before the handover inspection
PA inspection record — all defects identified by the principal agent at the PC inspection should be photographed and timestamped
Defects liability period — typically 6–12 months after PC; all defects notified during this period must be tracked with dates, descriptions, and rectification records
Attribution disputes — if a defect arises during the DLP, a contemporaneous photo record of site conditions at handover can prove that the defect did not exist at PC
Final completion — at the end of the DLP, the contractor should document that all notified defects have been rectified before requesting the Final Certificate
SnapStrux manages this lifecycle with digital snag lists, QR codes for unit-by-unit
defect submission, and status tracking from open through actioned to closed.
Dispute evidence
How a Good Site Record Protects Contractors
South African construction adjudication has grown significantly since the JBCC 6th
Edition introduced the statutory adjudication right. The CIDB Act and subsequent
regulations have made adjudication more accessible for subcontractors. But adjudication
is only as strong as the evidence presented.
A well-maintained digital site record gives a contractor:
Credibility — an adjudicator who sees a complete, contemporaneous digital record with timestamps is more likely to find the contractor's version credible
Specificity — "I have a SnapStrux observation from 14 March at 09:47 showing this instruction was given" is more powerful than "we were told verbally on site"
Volume of evidence — 50 timestamped observations with photos are harder to dismiss than 5 WhatsApp messages
Non-repudiable record — a digital record with GPS, timestamp, and photo metadata is far harder to dispute than a handwritten note dated after the fact
Quick preparation — an adjudication referral must be prepared quickly; a digital site record makes this possible without weeks of reconstruction
Defensible construction site records.
This is what SnapStrux is built to create. Not reports for their own sake — records that hold up when they need to.

Common questions
Frequently Asked Questions
A JBCC site record is any contemporaneous document maintained on a construction project
under the Joint Building Contracts Committee contract suite. Records include site
instructions, dayworks sheets, variation orders, site diaries, delay notices, and
defect lists. SnapStrux digitises all of these with automatic timestamps and GPS on
a mobile phone — creating a defensible evidence trail from the first day on site.
In JBCC adjudications and arbitrations, the party with the better contemporaneous record
usually prevails. Most South African subcontractors who lose payment disputes do so because
they cannot prove what happened when it happened — not because the claim is wrong. A
timestamped digital site record with photos is far more persuasive than a reconstruction
from WhatsApp messages and memory.
Contractors should record each SI by number, issuer, date, description, and whether a
corresponding VO has been issued. SnapStrux allows site teams to log SIs as categorised
observations with photos and timestamps, and to flag uninstructed or un-varied instructions
automatically. This creates a numbered SI register that can be exported as PDF or Excel.
Yes. SnapStrux manages the practical completion workflow with digital snag lists, QR-based
unit defect submission (occupants scan a code to submit defects without an app), and
status tracking from open to closed. PDF and Excel snag reports can be shared with the
principal agent via WhatsApp link and used as formal handover documentation.
At minimum: a site instruction register; dayworks records with times, plant, and materials;
a variation order register; a site diary; a delay register; photographic evidence of work
before it is covered; and a defect list at practical completion. SnapStrux digitises all
of these with automatic timestamps and GPS — creating records that are far harder to
dispute than paper, email, or WhatsApp.
