Subcontractor management for construction and infrastructure

On a construction site the risk concentrates in the subcontracting chain: several tiers of companies, workers who change week to week, and a principal's liability that does not thin out with distance down the chain. Verdana manages every tier to the same documentary standard and shows, on a per-project dashboard, who is qualified to work today and who is not.

The processes it covers are the ones that define the day for the site manager and the contracts team. Onboarding and qualification of each subcontractor with corporate, tax, social security and insurance documentation. A record for each worker with pre-employment medical clearance, employment registration, workers' compensation coverage and task-specific training. Site access authorization tied to that documentation. Periodic verification of wage and contribution payment records, which is the evidence that limits joint liability exposure. And progress certification, receipt and invoicing against the contract.

Expediting and warranty management matter here more than in most sectors. Critical materials and equipment arriving late compress a schedule that has no slack, so committed dates need active confirmation rather than passive hope. And installed equipment carries warranties whose terms often outlast the construction phase, which means the party that will eventually claim on them is not the party that bought them.

When an incident occurs or an inspection arrives, the file is what makes the difference. Verdana reconstructs the documentary status of any person or company on any past date, with the supporting evidence and a record of who approved what.
