Responding to an interior design tender (public & private contracts, EU 2026)

Interior designers and space designers are regular bidders for public procurement and structured private clients (local authorities, cultural institutions, landlords, property funds, companies). Unlike a building trade, they bid for design contracts: what is scored is the intelligence of the project, not the price of a material. Four families of contracts stand out.

• Interior fit-out and scenography of public facilities: layout of libraries, museums, reception areas, exhibition halls, offices and workspaces.
• Space design and fit-out: design and delivery supervision of interior spaces (retail, headquarters, tertiary spaces, public-facing venues).
• Project management / design assignments: an interior architecture mission in phases (concept sketch, schematic/detailed design, project, site supervision) on a refurbishment or restructuring operation.
• Framework agreements: recurring fit-out and space-design advisory assignments across an estate, triggered by subsequent contracts or call-offs over 1 to 4 years.

Across the EU the logic is identical in all 27 member states: a public operator publishes above the European thresholds on TED, below them on its national platform. An established interior designer may bid for a cross-border contract subject to freedom of establishment and to provide services, and to recognition of professional qualifications.

The first challenge is costing the fees. Unlike a bill of supplies, an interior design mission is costed in time: man-days per phase (concept, design, technical files, delivery supervision) × daily rate per profile (interior designer, project lead, draughtsperson, designer), or as a global lump sum. A poorly calibrated breakdown — missing phases, underestimated workload, unjustified daily rates — distorts the price score or destroys the mission's profitability. The split of man-days between phases must reflect the reality of production.

The second challenge is the methodology note. The buyer scores technical value on precise criteria: relevance of the concept and design intent, account taken of ergonomics and the occupants' real uses, accessibility (public-access buildings, reduced-mobility access, circulation), reasoned choice of materials and furniture, quality of the references provided, composition and skills of the team, schedule and supervision method. A generic note copied from one tender to another, without a fine reading of the brief and the site, is heavily penalized: you must answer the consultation rules criterion by criterion and demonstrate an understanding specific to the place.

The third challenge is administrative and reference-related: any professional qualifications or registrations, insurance certificates, a portfolio of comparable projects, and the ESPD/DUME for EU public procurement. False or expired documents lead to rejection — and even criminal penalties for false statements.

The assistant starts from the tender: you upload the tender file (PDF), it extracts the buyer, object, brief, expected mission phases, award criteria and weighting, and the buyer's language. The methodology note is then structured to develop the most heavily weighted criteria first (design concept, account taken of uses, accessibility, references, team), in the contract's language.

For the fees, you enter your daily rates per profile and the estimated workload per phase, or you import your rate grid in Excel, CSV or PDF. The assistant computes each line (man-days × daily rate excl. VAT per profile), distributes the workload across the mission phases, applies VAT and totals, and exports an editable Excel fee breakdown. No figure is invented: a phase without an entered workload or rate is marked "to complete".

• Methodology note structured around the tender's award criteria (concept, uses, accessibility, references, team).
• Fee breakdown in man-days per phase or as a lump sum, costed from your real rates (Excel export).
• Pre-filled ESPD/DUME draft for EU public procurement.
• Deliverables in PDF, editable Word and Excel, in the buyer's language.
• Your rates, team profiles and references stay confidential, reusable across tenders.

You stay in control: the assistant produces a solid base that you verify, enrich with your own design intent and real references, and sign before submission. It replaces neither your design expertise nor legal advice — it removes the hours of formatting and calculation where the risk of error and the loss of time are highest.

A controlled response follows a stable sequence, whether the contract is public or private, in France or elsewhere in the EU.

• Monitoring: spot relevant interior fit-out, scenography and project-management tenders on the platforms (TED, buyer profiles).
• Tender analysis: object, brief, mission phases, award criteria and weighting, deadlines, references and required documents.
• Go/no-go decision: fit of references, team availability, understanding of the brief, achievable deadlines.
• Fee costing: breakdown in man-days per phase × daily rates, or a global lump sum consistent with the workload.
• Methodology note: design intent, account taken of uses and ergonomics, accessibility, material/furniture choices, references, team composition.
• Administrative documents: ESPD/DUME, insurance certificates, portfolio of comparable projects.
• Electronic submission before the deadline, with e-signature where required.

The BoostPro IA assistant handles steps 4 to 6 — the most time-consuming and riskiest — producing the methodology note, fee breakdown and DUME in under ten minutes from your real data. You focus your time on design (design intent, differentiation, references) rather than formatting and calculation.
