Road and sewer adoption is the process through which infrastructure on a private development is formally taken over and maintained by the relevant highway or sewerage authority. JLES helps developers address the outstanding technical, construction and remedial requirements needed to progress developments towards adoption.
An unadopted development will remain the developer’s responsibility until the relevant highway or sewerage authority is satisfied that the required works and documentation have been completed. This can create ongoing maintenance responsibilities, outstanding bonds, and delays to final completion. JLES investigates the reasons a development remains unadopted, establishes the outstanding requirements and delivers the works needed to progress the site.
Yes. JLES can investigate unadopted developments, identify outstanding requirements and coordinate the technical, legal and construction work needed to progress the site towards adoption. This includes both recently completed developments and sites that have remained unadopted for many years.
Yes. JLES is a contractor rather than a consultancy-only service. We take responsibility for the agreed works and use our approved contractor network to deliver specialist construction activities where required, while JLES remains responsible for coordinating the works and progressing the project.
Yes. JLES regularly works alongside adoption engineers, consultants, housebuilders, contractors, and adopting authorities. We can take responsibility for the construction and delivery elements while maintaining the existing professional relationships on the project.Although we undertake all legacy adoptions from site completions to sites 40 years old, our post build /estate completion service can be used during the construction process with JLES acting as your main contractor and managing agent to ensures phases are completed to the adoption standard during build period.
JLES structure payments around agreed stages of project delivery, rather than requiring the entire cost to be paid upfront. The specific payment points depend on the scope and structure of the individual project.
