Procurement standard

Five questions before a drone-cleaning bid makes the list.

A qualified bid names the contractor, the remote pilot, the aircraft, and the operating authority. It carries the site plan, the chemistry and runoff plan, the quality standard, the fallback method, and the correction path.

Bid qualification

Require the whole operating package.

Verify the operator, aircraft, and authority.

Ask for the named remote pilot, current certificate, aircraft registration, airspace plan, and any waiver the mission requires. Part 107 covers many small commercial UAS operations under 55 pounds. Controlled airspace and operations over people or moving vehicles require mission-specific compliance, and may require authorization, waiver, operating-category controls, or an exclusion plan. If the aircraft dispenses a substance, confirm whether the substance and intended use trigger Part 137. The bidder should document the operating authority for this site and this mission.

Verify the commercial package.

Require the contracting entity and proof that the policies and endorsements cover the proposed UAS operation and cleaning scope. Ask for subcontractor roles, crew, weather limits, emergency plan, and the named correction path. Limits belong to the property and the contract.

Decide whether aerial cleaning fits.

Large continuous exteriors, recurring maintenance, and sites where access equipment is difficult can favor an aerial pass. Active plazas need workable pedestrian and vehicle controls during the work. Recessed glass, edges, interiors, fragile systems, and bonded minerals can require a hybrid or hands-on method. Require a test area and a manufacturer-compatible process when surface or coating risk is uncertain.

Make every bid price the same result.

Give bidders the address, elevations, surfaces, current condition, and desired finish. Add the cadence, operating hours, tenant constraints, runoff requirements, and closeout standard. Make each bidder separate routine maintenance from restoration and price the fallback method for the areas a drone leaves.

Write acceptance before launch.

Define the test section, chemistry, visual standard, inspection points, and documentation before work starts. Cover excluded defects, touch-up, weather delay, and the correction process too. The winning method delivers the required clean for this property.
