The time lapse video, produced for Galliford Try and Southern Water, shows rock transported from Norway being used to build a new defence wall to protect Southern Water's underground storm tanks and the nearby historical site Fort Cumberland.
The Southern Water scheme, costing nearly £3 million, was carried out by its delivery partner Galliford Try and its subcontractor ABCO.
Project Manager at Southern Water, Kieron Kidwell, said: "These new rock armour defences will protect our underground storm tanks, some of which are vital in helping to stop homes in Portsmouth from flooding during stormy weather.
"These new defences also protect the nearby historical Fort Cumberland, and they make the area more aesthetically pleasing as a whole."
The old and crumbling concrete sea defences were demolished and removed in March 2017. Over the course of last year, several barges carrying thousands of tonnes of rock have visited the Eastney coastline.
The ships carrying the rock from Norway berthed at Southampton before being transported across on a barge to the beach area next to Fort Cumberland.
WCCTV captured time lapse footage showing the construction of the new defences.
As the location had no existing infrastructure, power or network cabling, WCCTV were tasked to provide a WCCTV Fuel Cell Site Tower to provide both site security and time lapse video recording at the site.
The Fuel Cell Site Tower is autonomously powered, delivers live and recorded video via wireless networks and has a 7m height meaning it can provide stunning images of ongoing works.
