Locus Project Documents

Payment timing mismatch. The EPC contract commits to a 30-day payment cycle, but the subcontractor agreement allows 45 days — creating a 15-day funding gap that could trigger cash flow issues on larger claims.

ContractA.pdf · p.12 · §4.3 Subcontract.pdf · p.7 · §3.1

Notification deadline conflict. The insurance policy requires notification within 48 hours of an incident, but the site safety plan says "as soon as practicable" — these could conflict if an incident goes unreported over a weekend.

Insurance_Policy.pdf · p.8 · §6.1 Safety_Plan.pdf · p.14 · §9.2

Completion date unclear. Three separate documents reference different completion dates: 15 March, 31 March, and "end of Q1" — this needs to be resolved before the next progress claim.

Who it's for

Built for people who read
documents for a living

Engineers

"Does our equipment spec match what the supplier is actually offering?"

"Show me every deadline we've committed to and flag anything overdue."

Accountant working with financial documents
