Our contractors BAM Nuttall have been carrying out emergency works at Shade Chapel, Todmorden to repair a partially collapsed culvert on Walsden Water. The repairs to stabilise the culvert are essential to prevent the watercourse from becoming blocked which could result in flooding of the local area.
So far the works have focused on over-pumping to divert the river flow around the culvert via Rochdale Road. This is essential:-
- to limit further erosion and damage to the walls
- for the safety of those working in the culvert
- to allow concrete repairs to the base of the culvert and walls.
Key stages of the repairs are:
- Over pumping installation
- Concrete pours into the base of the culvert to prevent further undermining of the walls
- Crash deck installation to provide protection for workers within the culvert
- Removal of failed beams and debris
- Installing temporary supports to stabilise the culvert
- Grouting voids behind the collapsed culvert
- Permanent repair of the culvert channel to provide long term protection from further damage.
The pumping arrangement is now in place and the first pour of concrete to the culvert floor is taking place over the bank holiday weekend. Temporary works will then be carried out as soon as possible with completion expected in mid May. Permanent works can then follow to rebuild the culvert and prevent any further erosion or damage. We will continue to keep you informed about the progress of these repairs and timescales for the work.
In line with government advice, we are continuing to deliver all of our Flood and Coastal Risk Management projects where it is safe for our teams and delivery partners to do so. We are following the latest guidance from Public Health England regarding safe working on construction sites. The safety of our staff, partners and the communities we work in remains a priority for us.
The latest government update can be viewed here:
Measures we have put in place to protect the workforce and local community include:
- Limiting the number of people attending site to those that are essential to delivering the work
- Enhanced routine cleaning of all facilities
- Social distancing including segregated break times
- Making sure briefings and lunch times are held outside
- Providing workers with protective equipment and clothing (i.e. gloves, with additional masks and goggles) when close proximity working is unavoidable.
If we did not progress with this work there would be the risk of a further collapse of the culvert, with flooding highly likely and the risk to life and property damage being substantial. Local people could also be forced out of quarantine resulting in Covid-19 containment concerns and additional strain on our already stretched emergency services.
Although we are currently unable to provide face to face public consultations or letter drops due to CV-19 restrictions, we will continue to keep you updated via the Eye on Calderdale website www.eyeoncalderdale.com and our Twitter account @EnvAgencyYNE.
