Question

To ask the hon. Member for Broxbourne, representing the Restoration and Renewal Client Board, what the estimated cost is for drone surveys associated with the restoration and renewal project.

The R&R Programme is carrying out tens of thousands of hours of complex building surveys and investigations to develop even more detailed records of the Palace of Westminster. These records are being used to inform design and planning, and future decisions on the essential restoration work required.

Two intrusive surveys, the Photogrammetric and Heating, Ventilation and Air-Conditioning (HVAC) surveys, have recently started which contain an element of drone surveys as well as other activities such as high-resolution photography. The total estimated cost of these surveys is £1 million although this covers a number of activities.

Due to how the activity schedules in these contracts are priced it is not possible to disaggregate the costs of the drone flights from the rest of the works being undertaken. However, it is anticipated that a significant portion of the costs will relate to the contractor resource required to deliver the surveys and the processing of the images taken (rather than the cost of the drones themselves).

This figure also does not include Delivery Authority internal staffing costs or the costs of the contractor planning and overseeing the overall survey programme because those costs cannot be disaggregated by individual survey.
