Responding to a window cleaning tender (public & private contracts, EU 2026)

Window cleaning and glazing firms bid for structured public and private clients: local authorities, schools, hospitals and clinics, landlords, commercial property funds, office-building managers, shopping centres. Glazed-surface cleaning is almost always periodic, which makes it a recurring contract.

• Standalone window cleaning service: a dedicated contract for periodic cleaning of a site's glazed surfaces (office building, school, station).
• "Glazing" lot of a cleaning contract: window cleaning is isolated as a separate lot within a wider premises-cleaning contract.
• Call-off framework: glazing interventions triggered by successive orders across a building portfolio, over 1 to 4 years.
• Multi-site contract: window cleaning of a dispersed estate (social landlord, branch network, hospital campus), with frequencies differentiated by site.

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. A central purchasing body can also offer cleaning contracts including glazing. An established firm may bid for a cross-border contract subject to freedom of establishment and recognition of qualifications.

The first challenge is the price schedule. In window cleaning, a line's price is not a material cost: it aggregates labor (hours × hourly rate) applied to a passage frequency, and an access means whose cost varies sharply — ground-level or carbon-fibre water-fed pole cleaning, mobile elevating work platform (cherry-picker, with hire or depreciation plus a certified operator), or rope access by a rope-access technician (certified for working at height). A reachable sill-level window does not cost the same as a roof skylight or an eight-storey façade. The schedule must therefore break each zone down by surface, frequency and access mode, with overheads, margin and contingency. A unit error (m² vs per-passage flat rate), a missing access means or an unsourced price distorts the price score — often a decisive share of the overall score.

The second challenge is the technical proposal. The buyer scores technical value on precise criteria: intervention methodology, organisation of frequencies and passage schedule, and above all working-at-height safety. You must demonstrate control of the fall risk — operator certifications, use and inspection of fall-arrest PPE, rope-access technician certification where relevant, prevention plan and authorisation of access means (platforms), zone signage, co-activity on an occupied site. Quality (streak-free result, purified water for poles, passage traceability) and the environmental approach (products, water use) are also scored. A generic proposal copied from one tender to another is penalised: you must answer the consultation rules criterion by criterion.

The third challenge is administrative: insurance certificates, proof of working-at-height qualifications, 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, lots, award criteria and weighting, and the buyer's language. The technical proposal is then structured to develop the most heavily weighted criteria first (methodology, working-at-height safety, access means, quality, references), in the contract's language.

For the price schedule, you enter your rates and parameters: labor hourly rate, passage frequencies per zone, chosen access mode (ground/pole, platform, rope access) and its cost, overheads, margin, contingency, travel. The assistant computes each line (labor × frequency + access cost), applies VAT and totals, and exports an editable Excel BoQ crossing surface, frequency and access means. No price is invented: an item without an access cost or a sourced rate is marked "to complete".

• Technical proposal structured around the tender's award criteria, with a distinct "working-at-height safety" section.
• Labor + access BoQ (pole, platform, rope access) costed from your rates and frequencies (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, standard frequencies and access-means sheets stay confidential, reusable across tenders.

You stay in control: the assistant produces a solid base that you verify, complete with your real references and certification proofs, then sign before submission. It replaces neither your expertise nor legal advice — it removes the hours of formatting and calculation where the risk of error is highest, in a trade where access and safety drive the price.

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

• Monitoring: spot relevant window cleaning contracts and glazing lots on the platforms (TED, central purchasing bodies, buyer profiles).
• Tender analysis: object, lots, glazed surfaces and expected frequencies, award criteria and weighting, deadlines, required documents.
• Site visit and go/no-go decision: access survey (height, skylights, occupied-site constraints), technical capacity, certifications, workload.
• Costing: labor × frequencies BoQ + access-means cost (ground/pole, platform, rope access), with overheads, margin and contingency.
• Technical proposal: answer the criteria item by item, methodology, working-at-height safety (certifications, PPE, prevention plan), passage schedule, quality.
• Administrative documents: ESPD/DUME, insurance certificates, proof of working-at-height qualifications.
• 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 proposal, BoQ and DUME in under ten minutes from your real data. You focus your time on strategy (price, choice of access means, differentiation, references) rather than formatting.
