EU regulations, real prices, mission preparation: concrete answers before commissioning a drone service.

• Sunlight and shading studies on a drone 3D model: method, priceLoss of sunlight from a building project, shadows cast on a photovoltaic roof: a drone-built 3D model simulates sun paths over the real environment, vegetation included. Method, 2026 prices.
• Drone spraying in steep-slope vineyards in France: 2026 rules, method, priceSlopes above 30%: spraying drones replace knapsack sprayers where tractors cannot go. What France's 2025 experimental framework allows in viticulture, how a campaign unfolds, 2026 per-hectare prices.
• Curtain wall and high-rise façade drone inspection: method, priceOffice towers and curtain walls: bonded glazing, gaskets, brackets — thousands of square metres impossible to examine from the ground. What drone inspection brings to landlords and property managers. Method, 2026 prices.
• Building rooftop extensions: the drone survey (roof, party walls), priceAdding floors to a building starts with an exact survey: roof geometry, party-wall profiles, rooftop structures, height limits. What drone photogrammetry brings to feasibility studies and permits. Method, 2026 prices.
• Retaining wall drone inspection: method, monitoring, priceCorniche roads, quaysides, walls on sloping streets: French municipalities manage kilometres of rarely inspected retaining walls. What drones document — bulging, cracks, drains — and how to monitor over time. 2026 prices.
• Green roof monitoring by drone: coverage, irrigation, maintenance, priceGreen roofs are multiplying under French regulatory obligations — but who checks they are alive? Coverage rate, dead zones, irrigation, membrane: what a photo, multispectral and thermal drone flight reveals. 2026 prices.
• Amusement ride and fairground attraction drone inspection: method, priceBig wheel, drop tower, roller coaster: between two approved-body inspections, drones document the steel structure — welds, bolted joints, corrosion — without a cherry picker or crane. Method, regulation, 2026 prices.
• Drone-assisted works acceptance: roof and façade quality control, decennial warrantyOn acceptance day, the roof and upper façades stay out of sight for both architect and developer. What a drone adds: precise, photographed and dated reservations, before the legal warranties start running. Method, 2026 prices.
• EV charging stations in car parks: drone siting surveys and thermal maintenance, priceSince 1 January 2025, French car parks with more than 20 spaces must install EV charging points. What drones add: siting surveys to plan the rollout, thermal maintenance of the charging cabinets. Method, 2026 prices.
• Concrete multi-storey car park drone inspection: corrosion, cracks, priceWith no roof waterproofing, exposed to tyre-borne chlorides and frost, the multi-storey car park is one of the fastest-ageing concrete structures. What drones document: cracks, spalling, visible corrosion. Method, 2026 prices.
• Marina pontoon inspection by drone: method, regulations, priceSunken floats, corroded cleats, overheating quayside pedestals: what a drone documents on marina pontoons without a diver or downtime. Method, coastal regulations, 2026 prices.
• Business park (ZAE) inventory by drone: method, priceFrench law requires public authorities to keep an inventory of their business parks, updated regularly. What drones bring: orthophotos, actual land use, vacancy, roof potential. Method, 2026 prices.
• Collective EPC and works plans: drone thermography for condominiums, priceCollective energy performance certificates and multi-year works plans: French condominiums must document the thermal state of their buildings. What drone thermography brings, method, 2026 prices.
• Riverbank and watercourse monitoring by drone: erosion, log jams, priceBank erosion, log jams, declining riparian forest: how drones help French river authorities monitor watercourses. Before/after flood surveys, photogrammetry, 2026 prices.
• Logistics and retail building roofs: drone inspection, priceHectares of steel deck and membrane, smoke vents, skylights, soon solar panels: how drones inspect large logistics and retail roofs without sending anyone up. Method, thermography, 2026 prices.
• French legal brush-clearance obligations (OLD): drone mapping and monitoring, priceIn French wildfire-prone areas, brush clearance around buildings is a legal duty. How drones map the plots concerned and verify execution, for municipalities and owners alike. 2026 prices.
• Drones in orchards: tree counts, blossom, frost, canopy volumes — priceFruit growing: what drones bring to the orchard — tree and gap counts, blossom monitoring, frost damage assessment, canopy volumes, vigour. Method, sensors, 2026 prices.
• Buying drone services through public procurement: a practical guide for French authoritiesThresholds, specifications, award criteria, operator and insurance checks, data ownership: how a French public authority buys drone services within procurement rules, without getting the deliverables wrong.
• Livestock buildings: drone inspection and thermography, priceFibre-cement roofs, rooflights, ventilated ridges, solar panels: how drones inspect livestock buildings without sending anyone up and without stressing animals. Ventilation, condensation, biosecurity, 2026 prices.
• Reforestation monitoring by drone: survival rate, game damage, priceForest plantations: how drones count seedlings, measure survival rates, spot game damage and weed competition. Monitoring required by French reforestation aid schemes and carbon projects. 2026 prices.
• Hospitals and healthcare campuses: drone inspection and thermography, priceMulti-building campuses, crowded technical roofs, energy obligations, absolute service continuity: how drones inspect hospital real estate without scaffolding or interruption. Method, helipad, 2026 prices.
