Measured from HYDREAULYS's own published record — no estimates, no generic advice.

Plan for about 27 days to prepare a bid — that is the median gap between publication and deadline across 6 of their tenders.
They publish about 0.3 tenders a month, measured over 69 months of history.
Half of their 8 awarded contracts are worth €6.3m or less — size your bid to that range.
Most of their buying falls in architectural, construction, engineering and inspection services, business services: law, marketing, consulting, recruitment, printing, security, sewage, refuse, cleaning and environmental services.
Their most frequent suppliers are EGIS EAU SAS (2), INFRANEO (2) — expect to bid against incumbents who already know this buyer.
