Waterways in the North East region have been affected by the recent flooding. Here you can find more details and the most up to date news.
Since Boxing Day we’ve been working tirelessly to deal with the flooding damage to Elland Bridge and Crowther Bridge on the Calder & Hebble Navigation. See what we've been up to below.
This week, work continued to install the considerable number of ducts on the bridge required for utility services. Pouring of concrete around the ducts to bring the bridge up to road level will commence next week. Northern Gas Networks, Yorkshire Water and BT are all on site carrying out planned work to install new services on the bridge approaches and will move onto the canal bridge itself once the ducts have been installed. Stone masons have continued to build the masonry faces to the spandrel wall using the original stone.
This week, work has taken place on casting the concrete bridge saddle which has now reached service duct level in readiness for commencing installation of ducts next week. Work also continued on casting the approach walls at each corner of the bridge. Northern Gas Networks commenced two weeks of planned work on installing new pipes on the river bridge and will move onto the canal bridge once the ducts have been installed. BT will commence 10 days of civil construction work next week.
This week, work has continued on casting the wing walls in readiness for pouring the mass concrete next week. The temporary metal ‘colliery arch’ which will support the voussoirs stones whilst they are laid was lifted into position.
A site meeting was held with the seven utility companies and their contractors to finalise details for the diversion of services back in to the new bridge. This work will start next week with Northern Gas Network.
Stone masons have continued to lay masonry and three of the four wing walls are now above water level.
This week, the seven precast arch sections and four precast spandrel sections were crane lifted into position. A successful press photo call took place on Tuesday with BBC and ITV local news, Radio Leeds and five newspaper photographers in attendance.
The structure is now looking more like a bridge which the local residents are very pleased to see. Stone masons are continuing to cut and dress the stone off site and will commence laying stone walling next week. A meeting with the seven utility companies took place this week to discuss and agree work to divert the services off the temporary bridge and back onto the new bridge. This work will commence on 10 October and take around 11 weeks to complete.
A significant milestone was reached this week with the reconstruction of Elland Road Bridge following the floods last Christmas.
Elland Bridge Arch Lift
Work has been completed on casting the concrete arches which will be brought to site and lifted into position from Monday of next week. The design for the tie-in walls at the NW and SE corners of the bridge has been progressed this week and we have had subcontractors on site looking at the practicalities of constructing these. The masons have been working off site to produce the facing stone and the four no. springer stones for the bridge.
Work has now been completed on casting the concrete wing walls ready to receive the pre-cast concrete arch. Next week, localised clay dams will be constructed to enable building of stone wall below water level to begin on the southern abutment. Delivery of the pre-cast arch sections is now confirmed for 26 September – 2 October.
Work has continued on the shuttering and casting of the concrete wing walls ready to receive the precast arch sections. The seven precast arch sections are due to be lifted into position on 19 September when the opportunity will be taken for some publicity of this key stage in the construction of the bridge. The stone mason has now completed cutting of the stone required for the bridge wing walls and will be on site next week to commence construction of the tie in to the approach walls on east elevation.
Work continued on the shuttering and steel reinforcements for the wing walls this week and BT completed construction of the new equipment chamber and cable ducting to the bridge site. The arch voussoirs stones have been cut to size and laid out in the shape of the arch to enable a detailed inspection to be made to determine which stones need to be repaired or re-faced. The upstream arch has been subject to more weathering and sustained more damage during the floods. The stone mason has now started on cutting the stone required for the bridge wing walls.
Work continued on the shuttering and steel reinforcements for the wing walls this week. BT Openreach continued the construction of the large equipment chamber.
A site inspection took place at the stone mason’s yard to view the cut voussoirs stone and agree specification for the re-dressing of damaged or badly worn voussoirs and walling stone. As enough good quality stone has been recovered, the new bridge will contain all stone from the old bridge with no new stone required to complete it.
Work on the cast reinforced concrete north and south bridge abutments was completed on site this week. BT Openreach started construction of a large equipment chamber and ducting in preparation for data cable diversion later. The arch voussoirs stone is now being cut, re-faced and marked up ready for installation in the new bridge. Flood branded site signage was installed on the temporary footbridge explaining the cause of the damage, demolition and work to date at the bridge. This is proving a popular read with the local residents.
Work on the concrete abutments and piling for the new wing walls has continued this week. The order for the casting of seven bridge arch sections has now been placed with a specialist pre cast concrete manufacturer , these will now be prepared and are expected to be ready for installation around 29 August. The arch voussoirs stone from the old bridge are now being taken to a stone mason’s yard for cutting to size ready for installation in the new bridge, this work will take around four weeks to complete.
Work has continued on preparation of steel reinforcement and shuttering for concrete to complete the bridge abutments. This should take place next week. Final design drawings for the arch have been completed. Orders will now be placed for the casting of the arch sections off site. This work will take around six weeks to complete.
Specialist stone masons have inspected the stone from the original bridge, stored off site. Next week, they will start to take the individually carved arch voussoir stones to a local mason’s yard to be cut down to the depth required to be re-used in the new bridge. A meeting took place with all the utility companies to discuss the proposed ducting arrangements in the new bridge and ensure these fit in with their requirements. They also discussed a provisional programme for diverting utility services back into the new bridge – expected to commence in October.
Following a busy weekend completing concrete abutments, the canal opened this morning at Elland Bridge and the first boat has gone through.
Permanent piling was completed this week with the piling contractor demobilising from site on Tuesday. Work on constructing the concrete abutments and tie slab on the canal bed will continue next week. After which the canal can be re-watered and a section removed from both clay dams to allow boats to pass through. It is expected that the canal will re-open to boat traffic on 4 July.
After the relocation of the temporary works piles to the south last weekend, we continued this week with the installation of the permanent piles to the foundation of the new bridge. These works are progressing well and all piling is due to be completed Tuesday/Wednesday of next week, after which will we commence with the installation of the reinforced concrete tie-slab followed by the reinforced concrete abutments. The formal planning permission for the new bridge was received this week.
Following the removal of additional unforeseen obstructions from infront of the temporary works piles last week, some minor displacement of the pile line on both sides was noted, over last weekend and at the start of this week. No further movement has been recorded since last Friday but we will continue to monitor daily.
As the working areas between each pile line is only limited, this encroachment impacted on our positioning of the permanent piles for the new bridge abutments. After reviewing all the options collectively – and after consulting with Calderdale – we decided that the best option would be to relocate the position of the bridge 250mm to the south.
Clay dams were installed either side of the bridge site and piles driven in as part of the temporary works to facilitate construction of the new bridge. (Photo shows the dam in the foreground and bridge site). An over pumping system has been installed consisting of 3 x 4in pumps which will ensure that water can be passed around the site maintaining water levels in the rest of the canal. Over the weekend, a fish rescue will be carried out and water pumped out between the dams to ensure a dry site.
Demolition of the bridge completed this week with all stone taken off site. This allowed installation of two temporary clay dams to start three days ahead of programme. These will take around five days to install with around 200tonnes of material per day being brought in. After this the canal between the dams will be dewatered in readiness for foundation construction.
Completion of demolition allowed a window of opportunity for boats stranded at Elland Wharf since Christmas to leave towards Sowerby Bridge, one boat took up this opportunity after a channel had been prepared through the bridge hole by the contractors.
A Site Progress Meeting was held on Thursday when design, programme and methodology were discussed. The final bridge design is now being amended taking into account comments from the Canal & RIver Trust engineering team and utility companies.
Demolition of Elland bridge has continued this week, with stones being lifted, sorted, crated, shrink wrapped and removed to a secure Calderdale Council site. The design team met on Thursday, foundation design is now complete and draft bridge design will be completed next week. This will then be shared with the utility companies to ensure it meets requirements.
Demolition of Elland Bridge started on Monday 25 April. Pontoons with crash mats were floated under the bridge and the stones marked up ready for removal. The stones will be carefully lifted, sorted, crated, shrink wrapped and removed to a secure Calderdale Council site. This work will continue for the next 4-5 weeks.
The next stage of the works at Elland Bridge was carried out. Installation of a temporary bridge to house all the service cables and pipes using a 750t crane.
The temporary service bridge is now installed which will allow all of the utilities to be moved away from the existing bridge. Once all of the utilities have been moved we will be demolishing the bridge to allow the navigation to be reopened at this point. We are working with Calderdale Council to demolish Crowther Bridge during the same period.
Boxing day floods
Elland Bridge has suffered structural damage. Engineers have worked with the Council on installing a temporary footbridge, which is now installed.
Engineers have now carried out a detailed inspection and it has been agreed that it will need to be totally rebuilt. As the bridge is Grade II Listed, the new bridge will re-use as much of the existing stone as possible. A temporary footbridge has been opened to re- connect the town of Elland and a temporary services bridge is being designed which will carry the large number of services whist the main bridge is re built. Rebuilding the bridge is likely to take until December 2016 to complete.
21/10/2016 Work has now been completed on the coffer dam and platform for the piling rig on the northern side in readiness for commencement of piling for the bridge foundations
14/10/2016 Work has now been completed on the coffer dam and platform for the piling rig on the northern side in readiness for commencement of piling for the bridge foundations.
07/10/2016 Work has now been completed on the coffer dam and platform for the piling rig on the northern side in readiness for commencement of piling for the bridge foundations.
This week work has been completed on the north cofferdam, excavation to canal bed level and installation of the temporary platform for the piling rig. Following completion of the additional ground investigation, the northern foundations have now been re-designed to take into account underling geology. Work on the permanent piling of the northern bridge foundations will commence on 10 October.
Piling of the cofferdam to the North abutment has been completed within this week. To do this we had to close the footpath between 8am and 5pm to allow the works to progress safely. We have been continuing to liaise closely with Cromwell Nature Group to ensure that any inconvenience has been kept to a minimum.
Following completion of the ground investigation, work will commence on the piling for the northern side cofferdam. This will enable the northern bridge abutment to be constructed below water level. The stone mason has also started inspecting the stone recovered from demolition. A lot of the stone was damaged or lost during the floods so stone will have to be sourced from that not required at Elland Bridge or bringing in new stone.
This week additional Ground Investigation has been carried out on the northern side of the canal to determine the exact nature of the underlying geology and ensure the correct foundation design solution has been adopted. Work will commence on the northern side cofferdam to enable construction of the bridge foundation.
The temporary access ramp and pontoons have been completed on the off side of the canal. The access ramp has been trimmed up and the access into the canal has been safety railed and crash barriers installed. 200Tof puddle clay has been placed into the canal to form part of the temporary works for access to accept the cofferdam sheets during the pilling.
Work Continued on construction of the temporary access ramp down to canal level this week. The floating pontoons required to allow plant to access the southern side of the canal were delivered to site and manoeuvred into position. Two pontoons will be fixed to the canal bank and two will be moved into position when required. This will ensure the canal can remain open throughout the summer. The temporary access arrangements should be completed next week.
Due to ground investigation findings, the temporary access arrangements and final bridge foundations details have been amended resulting in a delayed start to construction. However work has started this week on the revised access ramp down to water level. To maintain an open navigation through the site during the summer, plant access to the southern side will be by moveable unifloat pontoons. Final ‘construction issue’ design drawings were issued to the contractor this week.
100 tons of stone was delivered to site as construction of the temporary access down to the canal continues
A meeting was held on site to consider the final design of the bridge foundations in light of ground investigation findings to ensure that the correct solution is chosen.
Final design drawings were completed for the pre cast bridge arch which will be similar to Elland and the order for the casting of this arch will be placed next week.
Work has continued this week on preparation of the foundations for the temporary bailey bridge. This should be ready to lift into position next week. Our design consultants have been revising drawings for the bridge (which will be very similar to Elland Bridge) and will issue final drawings next week. Planning permission for Crowther bridge was granted by Calderdale Council this week.
Following a busy weekend completing concrete abutments, the canal opened this morning at Crowther Bridge and the first boat has gone through.
Work has continued this week to remove the remaining debris from the channel and take stone off site for storage and re-use in the new bridge. The temporary dams were removed from site at the end of the week and the channel made ready to re-open to boat traffic. A temporary Bailey bridge and cofferdams will be installed to enable work to continue with an open canal. It is expected that the canal will re-open to boat traffic on 4 July.
Work has continued this week to remove the debris from the navigable channel. We have left the portable dams in place over the weekend to allow time for the suspended sediment to settle to the canal bed and intend to remove these next week. Next week we will continue to remove debris from the site and the reclaimed stone will continue to be sorted and placed on pallets for re-use. The next stage will be to install foundations for the temporary bailey bridge across the canal.
This week we overcame the problems with ensuring the seal to the fabric dams, the bridge was fully demolished and we are on with clearing the debris and salvaging stone masonry. Following this we will be installing the foundations for a temporary bailey bridge, which will cross the navigation downstream of Crowther bridge and allow access to both sides of the canal, whilst maintaining a navigational clearance. We remain on programme to have the navigation open by the 4 of July.
This week, fabric dams have been installed either side of the bridge, and an over pumping system installed to allow water to be passed around the site. Demolition of the bridge will commence next week with stone from the bridge being retained and stored on site for re-use in the new bridge.
Trees were felled this week to allow plant access to the bridge. The adjacent Cromwell Bottom Nature Reserve members carried out a ‘watching brief’ for nesting birds over the weekend before felling. The contractor commenced setting up a compound and storage space in readiness for demolition next week and completed slip trenches to ensure all services in the bridge have been isolated.
Ground Investigation drilling was completed this week. Discussions have commenced with landowners regarding access required to ramp down into the canal. Draft foundation designs will be completed next week.
Since the December 2015 Floods in Leeds there has been a great deal of clean up activity and preservation on the River Aire. Please visit River Aire Care for more details and to register to volunteer.
