Managing Subcontractors: Complete Guide for Perth Builders
Most construction work in Perth is delivered through subcontractors. Managing them well is the difference between profitable projects and costly disasters.
Before They Start
Written subcontract agreement covering scope, price, timeline, variations process, payment terms, insurance requirements, and dispute resolution. Verify ABN, licences, and insurance. Conduct site induction.
During the Job
Weekly coordination meetings. Clear communication on schedule changes. Manage trade sequencing — don’t schedule the painter before the plasterer is finished. Regular quality inspections. Address issues immediately, not at the end.
Payment
Pay on time, every time. Weekly payment is the gold standard for subbies. Progress claims for larger scopes. Retention (typically 5%) held until defects liability period ends. Late payment is the #1 reason subbies don’t come back.
Dispute Resolution
Document everything. Variations in writing before work proceeds. Photos of completed work. The Building Commission WA offers dispute resolution services for construction contracts.
