Facade Renovation Technical Proposal: Winning Rehabilitation Contracts in French Public Procurement
Facade renovation is a technical market where the preliminary diagnosis and choice of treatment system determine the quality of the proposal. The buyer expects thorough analysis of the existing substrate, treatment prescriptions adapted to each type of damage, and particular attention to heritage and environmental constraints.

What these figures tell you
With 973 winning companies for 1,523 contracts, a company wins on average 1.6 contract(s) per year in this segment.
The median amount of 80,731 EUR indicates the size of consultation to target first.
The median duration of 14 months shows how often these contracts return to tender.
The median is used rather than the average: a handful of very large contracts is enough to distort an average.
What the buyer expects in a facade renovation proposal
The evaluator seeks assurance that you understand the facade condition and its pathologies. A comprehensive substrate diagnosis (hammer sounding, adhesion testing, moisture measurement, defect survey) is the cornerstone of the proposal. The buyer then checks consistency between diagnosis and prescribed treatment system: each damage type must have its specific solution.
Heritage constraints carry significant weight: in protected areas (historic monument perimeter, AVAP, listed site), approval from the Architecte des Bâtiments de France (ABF) is mandatory and determines choice of colours, materials, and techniques.
Technical structure of an effective facade renovation proposal
A winning facade renovation proposal centres on three axes: diagnosis, prescription, and implementation.
Diagnosis and defect survey
Detail your diagnostic methodology: visual inspection, hammer sounding for delamination detection, adhesion pull-off testing, moisture measurement, existing material identification. If a site visit has been carried out, attach annotated photographic report. Map defects facade by facade.
Prescribed treatment systems
For each identified defect type, propose a complete treatment system conforming to applicable DTUs (DTU 42.1 for coating systems, DTU 26.1 for renders, NF EN 1504 for concrete repair). Detail products: manufacturer, reference, technical data sheet, compatibility with existing substrate.
Heritage and regulatory constraints
In protected areas, the proposal must demonstrate your command of ABF constraints: materials compatible with historic buildings (lime renders vs cement, mineral wash vs film-forming paints), traditional repointing techniques, moulding restoration. Heritage Building certification or references on listed buildings are major assets.
Errors that penalise a facade renovation proposal
Prescription without diagnosis — Proposing treatment without preliminary substrate diagnosis discredits the bid.
Ignoring ABF constraints — In protected areas, non-compliant colour or material choices lead to bid rejection after ABF review.
DTUs not referenced — Facade renovation systems must comply with applicable DTUs. Not citing them suggests standards are not mastered.
