All 7 Documented Cases
Extended Cash Conversion Cycle from Retention Hold & Defects Liability Period
5–10% of contract value held for 12–24 months = estimated working capital cost of AUD 50,000–500,000 per AUD 1M contract (based on 8–10% annual cost of capital). Per contractor managing 5–10 concurrent projects: AUD 250,000–2,500,000 in tied-up capital.Retention ranges from 5–10% of progress payments in Australian construction contracts. Staged release (practical completion + defects period) extends the hold period 12–24 months. Disputes over release conditions (e.g., undefined 'substantial completion') delay final payout. Smaller contractors face severe cash flow strain during this period. Manual tracking of punch-list items and defect resolution status introduces verification delays.
Manual Retention Trust Account Tracking & Reconciliation Overhead
20–40 hours/month per project (at AUD 75/hour loaded cost) = AUD 1,500–3,000/month per project. Portfolio of 5 projects = AUD 7,500–15,000/month (AUD 90,000–180,000/year). Audit failure/rework due to manual errors: AUD 5,000–15,000 per incident.Contractors managing retention trusts must prepare monthly/quarterly statements for subcontractors and lodge annual Form 2 audits. Manual tracking requires: fund deposit verification (within 5-day window), GST split accounting (retention lines vs. cash portions), interest accrual on trust accounts, and subcontractor statement preparation. Multiple concurrent projects multiply administrative burden. Spreadsheet errors (transposition, missed deposits) cause audit failures or fines.
Poor Contract Drafting & Retention Term Ambiguity Leading to Disputes
Per contract: AUD 20,000–50,000 in dispute resolution costs + legal fees + working capital costs. Portfolio of 20 contracts annually: AUD 400,000–1,000,000 in preventable dispute costs.Many construction contracts contain vague retention release conditions ('completion', 'satisfaction', 'final approval'). Contractors sign contracts without understanding cash flow implications. Retention may be contingent on external events (COO, head-contract completion, third-party approvals) beyond the contractor's control. Lack of objective verification metrics (e.g., punch-list sign-off procedures) creates prolonged disputes. Late contract review (during project, not pre-bid) limits negotiation leverage.
Mandatory Retention Trust Account Audit Non-Compliance Penalties
Automatic statutory fines (amount not specified in legislation but triggered immediately upon late lodgement). Estimated annual compliance cost: AUD 5,000–15,000 per contractor (based on typical trust audit fees + penalty risk).Contractors in Queensland managing retention trusts face automatic fines for late Form 2 lodgement to QBCC (due 60 days after trust year-end). Manual tracking of retention across multiple projects creates bottlenecks. Statutory trust requirements apply to all contracts; projects over $20M in NSW and contracts over $20,000 in Western Australia (as of February 2024) have mandatory retention trust accounts.
