Public Rights of Way
As part of our construction planning, we're consulting with users of the Public Rights of Way tracks along the cable route, to ensure that any closures are communicated in a clear and helpful way. We've established a PRoW Liaison Group, and have been working with Parish Councils to raise awareness of the coming works.
If you would like to see how we're proposing to manage the temporary closures, please see the illustrations below. A detailed schedule of works will be shared before construction starts, and any closures will be detailed.
For more detailed information on proposed PRoW closures and diversions, please visit the PRoW page here.
If you would like to join the PRoW liaison group, please email firstname.lastname@example.org with and expression of interest.

Update on Current Work
Work has virtually finished on the cut and fill exercise of the substation. Works are now progressing onwards with the installation of the main equipment, as well as local mitigation planting. The Public Rights of Way have been diverted and are being maintain by the site contractors.
As part of the on-going works at site, we will be conducting one late night activity between 20th September and the 23rd September, to fill two transformers on site with oil. The work involves minimal noise and light impacts, but requires a continual filling activity which will push working hours on those days to the early hours of the next morning. The two transformers will each take roughly twenty hours to fill and a third nights work has been requested by ROW in case any unforeseen events occur that require work to continue into a third night. Every effort will be made to complete works as quickly as possible
During these times, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works. During the out of hours working period Philip Tarren of EON can be contacted on 07590 483 493.
Ecology fencing has been erected ahead of construction works
Both the Brighton Road and Henfield Road crossings have been successfully completed. We will be commencing with top-soil stripping and duct installation in the remainder of the stage once the ground had sufficiently dried out.
WSCC have also granted a weekend working application for the 20th & 21th August, for the installation of a specially designed trench frame in bog land at Field 86 to prepare for cable duct installations. Unfortunately there is limited availability of specialist who are required to oversee these works and therefore this work can be conducted during the normal working week. The additional working hours have been agreed by WSCC for 13:00 – 17:00 on Saturday 20th and 09:00 – 16:00 on Sunday 21th August.

Horn Lane crossing was successfully completed. Work continues with the installation of the onshore cable ducts through Stage 4.
Edburton Road crossing has been successfully completed. Top-soil stripping has commenced in this stage, and trenching works are continuing
Tottington Mount has been completed, including reinstatement of topsoil.
The remainder of the stage, excluding the crossing of South Downs Way, has been trenched, had ducts installed, and had trenches backfilled.
Topsoil stripping, trenching and installation of ducts has been completed across this stage. Soil has been backfilled in the trenches.
The Horizontal Direction Drill underneath the River Adur has now been successfully completed. The majority of the rest of the stage has also been completed, and as part of those works we will be conducting some activities over the weekend of the 30th and 31st July, during the additional hours of 13:00 – 17:00 on Saturday and 8:00 – 17:00 on Sunday. The works involve no HGV movements to site and minor preparatory works for activities commencing the following week.
During this time, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works. You may also contact the site manager Jacob Gillbard on 07753285299 during these hours.
All of the ducting in this stage has now been installed, and the subsoil backfilled. Top-soil will be reinstated once installation works have been completed. As part of those works we will be conducting some activities over the weekend of the 30th and 31st July, during the additional hours of 13:00 – 17:00 on Saturday and 8:00 – 17:00 on Sunday. The works involve no HGV movements to site and minor preparatory works for activities commencing the following week.
During this time, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works.
All ducting in this section has been completed and the soil backfilled.
Carillion have also been granted consent this coming weekend on the 24th September between the hours of 8am and 6pm to conduct some jointing bay activities in preparation for further works the week after. This will involve no HGV movements and minimal staff working on site. During these times, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works.
The ducting for the railway drill has now been installed. We have been removing certain equipment from site, in preparation for future installation works over the coming months.
Carillion have also been granted consent this coming weekend over the 24th and 25th September between the hours of 8am and 6pm on both days to conduct some final installation exercises in the stage. This will involve no HGV movements and minimal staff working on site. During these times, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works.
The HDD Drill underneath the Railway has now been successfully completed. We've also completed the compound set-up at Brooklands park, fencing out and boarding the area required to undertake the landfall drill. Last month Volker Infra successful installed two ducts out to sea to form part of the works required to bring the subsea cable onshore. During last month we have also extended the ducting further out to sea into deeper waters (with some minor onshore support activities) to prepare the site for the installation of the offshore export cable
As part of those continued works, ROW have been granted consent to conduct some limited out of hours activities within the Brooklands site to support the cable installation activities for the offshore export cable between the 8th September and the 1st November. This will involve some minor activities on two separate days to aid the installation, but as these activities are dependent upon a supporting marine vessel which can only work in certain sea-state conditions, there is potential this work could extend into the late hours during a given day. If late working takes place, then this will only be for two separate days within the period consented and work on a given day will be completed within a 24hr period.
Please note that whilst the consent is for out of hours work during the period highlighted above, work will not be undertaken continuously for 24hrs during that period. The consent is in place to allow work intermittently on two days outside normal working hours.
We have also been given consent between 25th August and 25th September for some small onshore activities taking place in the Brooklands Park area assisting the marine vessel with its duct laying activities. Due to tidal and sea-state conditions limiting the working hours of these marine vessels, some of this activity needs to take place out of normal working hours. This will involve the use of a pump on site and some minor vehicle movements to support those activities. It is likely the bulk of this work will take place during the latter period of the consented window. Please note that the original consent ran to the 16th September, but was extended by ROW until the 25th September recently.
We have also been given consent to work over the next two weekends (17/18th September and 24th/25th September) between the hours of 8am and 5pm, to allow some duct cutting activities to take place. It is likely these works will be conducted during the normal working week hours, but as the works require the support of a vessel at sea, which is limited in the sea conditions it can operate in, ROW has applied for and been given approval to conduct works at the weekend if the weather dictates that is required. All noisier activities will be focused to the middle of the weekend days to minimise impacts on local residents.
During these times, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works. During out of hours periods, Michael Overend can be contacted on 07773 207416
