S278 Works & Sewer Connection, Case Study, Gt Paxton
Objective
Our objective was to facilitate both Section 278 works and also an Anglian Water sewer connection, for a small one-off development on the main road running through Gt Paxton, Cambs.
About the project
The groundwork within the site had already done by our customer, and the foul drainage brought to the site boundary. The surface water had been taken care of within the site by the customer’s own groundwork team. The path outside the site also had to be resurfaced as part of the agreement between the contractor, and Highways. This included taking out existing kerbs and relaying new 6×5 kerbs, along a 30-metre stretch of footpath, and required a Section 278 agreement, which our customer had already taken care of as far as the bulk of the admin work was concerned.
Despite the works being on the main road through Gt Paxton, we had no option but to close the road, and set up a diversion due to the width of the existing road. The excavation for the sewer connection alone, left less than 3m of clear carriageway for existing traffic, which is not enough from Highways’ point of view.
However, with the road closed, this also enabled us to carry out the works a lot quicker. We planned to have two teams on the project, one carrying out the sewer connection, and the other preparing for the S278 works. And then the two teams would come together at the end of the project for reinstatement of the sewer connection works and also the resurfacing of the new footpath.
Although our customer had already done the bulk of the admin work in relation to the Section 278 works, we still had to apply to Highways to carry out the work, and this included traffic management applications, in this case a TTRO ( Temporary Traffic Regulation Order) which enabled us to close the road. As part of this application we have to have a physical diversion designed by a third party, for agreement by Highways. For the sewer connection, we had to apply for a Section 50 from Highways. Our customer already had already done the Section 106 to Anglian Water, which is the application to connect to their public sewer.
During the applications process, our customer suggested that we allow Anglian Water to collaborate with them, with regard to the ‘clean water’ connection for the site. This meant that we would work alongside them on the same road closure, in order that the road wouldn’t have to be closed a second time, for the Anglian Water works.
We managed to make the connection onto the public sewer on Day 2. The method of connection detailed in the Section 106 was ‘connection by junction insertion’, as this was only for one single property.
With the connection made and approved by Anglian Water that same day, we continued to excavate for and lay pipework to the boundary with the site.
The connection to the public sewer and all pipework was complete by the end of Day 3. On Day 4 we backfilled and compacted to Highways’ spec, in preparation for final tarmac reinstatement on Day 5
For the Section 278 works, we were required to remove the entirety of the existing footpath, and relay with 6×5 kerbs at the road. The sub base was taken out from underneath the old footpath to the required depth. Type 1 MOT granite was laid and compacted in layers in preparation for tarmac on top.
At this point the work was inspected and passed by the Local Highways Officer responsible for Section 278 works and tarmac was laid on day 5 for both the sewer connection and also the new footpath.
It was a pleasure to work with DGH Construction on this project and we look forward to working with them again.
