Frequently Asked Questions

What’s the difference between JBCC, NEC, and GCC payment certificates?

Kwehluka lokukhulu nguloku:

JBCC:

Monthly certificates tikhishwa yi-principal agent
14-day payment period
Standard retention release (50% practical completion, 50% final completion)
Clear variation order process

NEC:

Monthly assessments yi-project manager
3-week payment period
Flexible assessment process
Compensation events (variations) tiphatfwa ngendlela lehlukile

GCC:

Monthly certificates tikhishwa yi-principal agent
Payment period iyehluka (imvamisa 14-30 days)
Retention terms tiyehluka nge-contract
I-flexible kakhulu kune-JBCC

Certificate format ne-calculation methods kuyafana kakhulu, kepha timing, terminology, nezinye processes kuyehluka. Khetsa software lesekela contract form yakho.

Can I claim for materials on site that haven’t been incorporated into work?

Kuya nge-contract yakho. JBCC contracts tingavumela kukhokhwa kwe-materials letsite on site (sib. structural steel, precast concrete) uma contract ikusho. NEC ne-GCC contracts imvamisa ativumeli kukhokhwa kwe-materials on site. Hlola contract terms — uma materials on site atifakiwe, utawukhokhelwa kuphela uma materials seyifakiwe emsebentini.

What happens if the principal agent doesn’t issue a certificate on time?

Uma principal agent angakhiphi certificate nge-contract deadline, loko kuba breach of contract. Ungaba nelilungelo la:

Interest kuma-overdue amounts (uma contract ikuvumela)
Potential suspension of work (uma contract ikuvumela)
Dispute resolution procedures
Damages for breach of contract

Noko, zama kucala ulungise lendzaba ngekuchumana ngaphambi kwe-escalation kuya kuma-formal dispute procedures. Late certificates imvamisa ibangwa yizingcindezi te-resources noma timo te-admin letingalungiswa.

Noko principal agents kufanele babe fair — minor defects letingatsintsi ukusebenza akufanele kube sizatfu sekutsi kukhokha kophikwa. Contract imvamisa ichaza defect handling procedures.

How does retention work if practical completion is delayed?

Uma practical completion ibambezeleka, retention release nayo iyabambezeleka. Penultimate certificate (lekhipha 50% retention) ikhishwa kuphela uma practical completion seyifeziwe, kungakhatsaleki original programme date. Loko kusho kutsi:

Retention ichubeka ibutsana kuze kube practical completion
50% retention release iyabambezeleka kuze kube practical completion
Final 50% release iyabambezeleka kuze kube final completion

Plan-a loku kuma cash flow forecasts — delayed practical completion kusho delayed retention release.

What’s included in the final payment certificate?

Final payment certificate ifaka:
