Drone Technology Led High Rise Tower Block Inspections

Drone Technology Led High Rise Tower Block Inspections

THE PROBLEM

Planning and conducting multistory and High Rise Tower Block Inspections can be a headache for facilities management companies, local authorities, councils and housing associations. Routine maintenance and defect and dilapidation monitoring can be costly using traditional methods. Not only can traditional methods such as scaffolding, elevated platforms and rope access be costly, time consuming and invasive but they also have an element risk attached. A large number of these structures were built in the 1970s and have been retro fitted with external cladding to help with insulation, in some cases this cladding is not preforming as intended and problems such as cracking, water ingress, and in some cases cladding failing and coming away from the structure.

CASE EXAMPLE

Iprosurv were approached to investigate the use of drone technology to inspect a high rise tower block from a local authority housing association. the structure in question was built during the 1970s and retro fitted with external cladding in 2014. On routine inspections it was noticed that cracking had appeared in the cladding and large portions of cladding were coming away from the structure, this in turn had caused a health and safety issue for tenants entering and exiting the block and for the general public using walkways past the structure.

TRADITIONAL METHODS

Cost of traditional methods had been investigated and for inspection purposes were expensive and required time to get to site. Scaffolding was in excess of £250.000, rope access was also expensive and time consuming on site with the need to manually take mages and formulate reports and log each image to enable navigation around the structure.

TECHNOLOGY-LED METHODS

But there is another way, a way that is led by, facilitated and completed by drone technology. Drone high rise tower block inspections, a method that could reduce the cost of inspection by a factor of 100. Sound too good to be true? It’s not, it’s reality and we are helping clients across the country bring those theoretical savings to life.

THE SOLUTION

Iprosurv listened to the clients requirements and advised on the best course of action to take to enable drone technology to be used and to get the best output for the client.

From there Iprosurv started to plane the operation keeping the client informed at all stages of the planning and subsequent operation, the client was kept informed at every stage of the flight planning, Iprosurv facilitated all of the neccesasry flight applications, local authority applications, and police notifications.

The client had decided that they would require a 3D interactive model that would enable them to quickly identify issues and annotate measurements, and annotations on the model with the ability to share with other stakeholders.

RESULTS

Once the inspection had been completed the media was uploaded to the Iprosurv’s proprietary system where the data was processed through advanced analytics to the clients requirements in this case the 3d interactive model.

The client has the ability to inspect the 3d model and individual images that were produced to make up the model, the client also has the facility to make linear and volumetric measurements as well as apply risk ratings and annotations.

The data can be instantly shared through the Iprosurv portal with unique user access.

SAVINGS

The savings on access alone were in the region of £250.000 and the production of the 3d model data set allowed multiple stakeholders to view at the same time including surveyors, structural engineers, contractors, facilities management, health and safety, this resulted in better and faster decision making.
