WS ATKINS - ENGINEERINGOver the last five years, Ryan and the Harp team's expertise and honest salesmanship is everything I need and more. There is never any pressure to upsell — they give you exactly what you need. Every solution we have had, from video walls to control room displays, has been excellently designed, implemented and supported.
Joseph Knipe, IT Service Delivery Manager, Satellite Applications Catapult
TUBELINES - TRANSPORTHarp Visual has proved again that they have the ability to finish another project successfully. I have used Harp Visual services and product on a number of occasions and can certainly recommend them to anybody who is looking to install or upgrade their Control Room. It is a pleasure working with Harp Visual.
Brian Wise, WS Atkins
With Harp's success of a previous installation, the control room with the video wall was planned in at an early stage of the conception of Tubelines. Harp's known ability to integrate different feeds from sources was a high factor in choosing Harp again. Again they delivered a system on time and installed to a highly professional standard. As more centres are developed Harp will be considered first.
Ian Machen, Control Centre Manager, Tubelines
