EA Sluice Works
March 26 Update
With the Sluices gates now installed I have the demobilisation programme below with a final exit date of Friday 26th June where BAM will be completely offsite.
Over the last couple of months, the wet weather has hampered BAM to complete their remaining finishing works and demobilisation and envisage they should be complete by the end of June weather permitting.
The Environment Agency are also instructing additional finishing works which again is adding to the delay in finally completing the project.
Over the next few weeks BAM will complete the remaining works which includes but not limited to the following: –
Topsoiling & seeding the grasscrete paving already laid.
Installation of Signage
Vegetation planting
Filling in the void between the existing access track and the boundary of the sluice with the track matting already laid
Completion of all remaining electrical installation works within the sluice and snagging items raised during the last inspection.
Painting touch-up and general cleaning/ finishing of the Sluice ready for final inspection and takeover by the EA.
The final handover inspection was scheduled for late March. If it were accepted, the fencing around the Sluice Boundary would be removed and the asset would be returned to the EA. (this needs to be confirmed)
At this point they will commence the demobilisation of the compound with the removal of the plant, materials & equipment, followed by all the site cabins. We will then remove all the compound hardcore and reinstate the field with topsoil and seed. This will take a number of weeks and again is subject to the weather and the condition of the ground beneath the hardcore.
Some sort of fencing will remain (Type to be confirmed) to prevent access onto the prepared topsoil to allow the new grass to establish.
01 October update
significant events are:
- Large numbers of persons attending site for the first gate acceptance test (1st October)
- Removal of the last two pumps requiring track closure 2nd – 3rd October
- Lorry to take away the last pumps and generator 6th – 7th October – after works are completed, the field next to the track will be clear for boat placement
Please note that these works are on the opposite bank further away from your property and should have less volume as a result.

We are looking to take advantage of the continuing good weather to progress things as once the flume is in place, with its capacity to pass more river flows than the pumps, the in-channel works we be much less vulnerable to interruption.
We are amending the temporary pumping arrangement to reduce the disruptive noise experienced so far, which will continue into this Saturday in order to complete the changes as quickly as possible to the benefit of all. As previously noisy works will not extend into the afternoon.
The next planned Saturday work is at the end of May when we will test the load capacity of the existing ground anchors securing the channel bed to inform our works to install more ground anchors in the summer. The load testing is not a noisy activity.

8th November 2024
As you may have observed the work schedule on site has reduced which is reflected in the attached programme.
At present we have one gang working with the excavator and dumper within the compound around the sluice.
There is minimal interaction with the routes around the compound except for pant crossing into the site yard occasionally.
We confirm the ongoing plan for no weekend working for construction activities.
In about three weeks’ time there will be a 60t crane on site to lift the lid of the new bypass chamber into position.

Saturday and Sunday, 17/18 August – placement of reinforcement on ) to fix the rebar to the Up Stream walls. Only plant on Sunday will be the excavator to feed the rebar into the sluice.
The August Bank holiday weekend there are plans to undertake formwork on Saturday only.
Here is the latest 4 weekly programme from Monday 12/08/24

Please see below an update from EA regarding the sluice gate replacement.
As you will be aware this spring and summer (so far) have been much wetter than usual resulting in the river flows being higher than we would expect at this time of year. The higher river flows are delaying our start of the in-channel works at the sluice. With drying weather we are hoping to be able to start the in-channel works on Monday. We are also looking at programme mitigation measures to be able to complete this seasons’ in-channel works before the normal start of autumn rainfall. In the first instance we will be increasing the bypass pump capacity to enable us to start the in-channel work and continue them with the flows we have been experiencing so far this summer.
In addition, we are looking to increasing contractor resources to be able to increase site productivity over the summer by carrying out more operations simultaneously. We are looking to increase the contractor working hours during the week to 7am (their current start time) to 7pm (from around 5pm). In order to be most productive during the normal working week some preparation would be required on the occasional weekend. We fully understand that the Club is for quiet recreation and has a rule for no noise after lunchtime on Saturdays. In keeping with this our contractor would cease noisy work at Saturday lunchtime, though still be active around the site in the afternoon. A potential exception to this would be the first weekend of August when a crane would lift steel reinforcement into the channel ready for a concrete pour the following week. The crane would not be active all the time, only needing to lower steel into the channel occasionally, pausing while this steel is fixed in place. We recognise that this would be a disturbance, but we are working to mitigate against a potential greater disturbance should the in-channel works over-run into the autumn.
Any questions please email Commodore or the Club Secretary.
