GCC 2015 — common questions

Where you’ll meet it: Civil engineering and infrastructure — municipal services, water, roads, sanitation — mostly public-sector. One of the four CIDB-endorsed standard forms. (A GCC 2023 edition now also exists — confirm which one your contract uses.)

What is GCC 2015 and where is it used?

The GCC 2015 is a standard construction contract published by the South African Institution of Civil Engineering (SAICE), written mainly for civil engineering and infrastructure work. It's very widely used on public-sector projects — municipal services, water, roads and sanitation — and is one of the four standard forms endorsed by the CIDB for public procurement, alongside JBCC, NEC3 and FIDIC.

Who administers it — is there an 'Engineer'?

Not by that name. Earlier editions called the administrator the 'Engineer'; GCC 2015 renamed this role the Employer's Agent, because the form is used across disciplines. The Employer's Agent issues instructions, certifies payment, and rules on claims and extensions of time. Although appointed by the Employer, they are expected to act impartially when certifying and determining. Check the Contract Data for the named agent and any limits on their authority.

How do claims and extensions of time work?

Claims are governed broadly by Clause 10, with the grounds for an extension of time in Clause 5.12. The key rule: deliver written notice of your intention to claim to the Employer's Agent within 28 days of becoming aware of the event, with particulars following, and updated monthly for ongoing events. Missing the 28-day notice can forfeit the entitlement, so treat it as critical and diarise it.

How do payment and retention work?

Payment runs on monthly payment certificates: you submit a statement, the Employer's Agent certifies the amount due, and the Employer pays within the period in the Contract Data. Retention is deducted as security up to a limit set in the Contract Data and released in stages around completion and the end of the Defects Liability Period. If a certificate isn't issued or paid, you may suspend the works after giving the required written notice.

What about penalties for late completion?

GCC provides for penalties (not 'liquidated damages' in the English-law sense) where you miss the Due Completion Date, at a rate per calendar day set in the Contract Data — it is project-specific, so read your Contract Data rather than assuming a figure. Penalties are usually capped, deducted via the payment certificates, and an extension of time granted under Clause 5.12 moves the completion date and relieves penalty exposure.

What happens if a claim is rejected?

Disputes are handled within Clause 10. Broadly, a dissatisfied party gives notice, the matter is first referred back for a decision (a 'dissatisfaction' step), and if still unresolved it escalates — typically to adjudication and then arbitration or court. The exact sequence and whether adjudication or arbitration applies are set in the Contract Data, so verify the elected route on your specific contract.
