1. Which tenders concern an MEP design firm?
Direct answer: an MEP firm mainly responds to design and engineering-management missions on the technical lots, both public and private.
The MEP engineer and the MEP design firm intervene before and during the works on a building's technical lots: heating-ventilation-air-conditioning (HVAC), sanitary plumbing, high- and low-current electrical, smoke extraction, building services. Their contracts are intellectual services, distinct from works contracts. Several families stand out.
- Design studies for the technical lots: HVAC, plumbing and electrical sizing of a public building (school, hospital, library, social housing), from sketch to the tender documents for the works firms.
- Engineering-management (project supervision) missions in co-contracting: the MEP firm works within a team led by an architect or a lead contractor, on its technical lots, from design to site supervision.
- Energy audits and performance studies: audit of a building estate, energy master plan, feasibility study for a change of heating or cooling system.
- Engineering framework agreements: design or client-assistance missions triggered by successive call-off orders over 1 to 4 years, for a property portfolio or an authority.
Across the 27 member states the threshold logic is identical: a public buyer publishes above the European thresholds on TED, below them on its national platform. An MEP firm established in one country may bid for a cross-border mission subject to freedom to provide services and recognition of its engineering qualifications.
Key takeaway
For an MEP engineering mission, the technical score (methodology, team, references) frequently weighs 60% or more of the overall score, more than price. The methodology proposal is therefore the decisive document, even more than the costing.
