At Kemp, we provide precise and reliable As-Built and Adoption Surveys to ensure your completed works match the approved design and comply with the standards set by adoption authorities.Â
Whether you’re delivering new housing, infrastructure, utilities, or commercial developments, our surveyors supply the verified data you need to demonstrate that construction has been completed correctly and ready for sign-off. From drainage and highways to utilities, structures, and public realm elements, we help move your project smoothly from construction to submission, approval, and adoption.
Our services support a wide range of statutory and private adoption requirements, including S104 sewer adoption (supported by CCTV and topographical surveys), S38 highway adoption (topographical surveys), S278 and S228 highway improvement works (topographical surveys), and S185 sewer diversions.
Clients across the South West rely on Kemp because our surveys are consistently accurate, clearly presented, and accepted by authorities and consultants alike. We work closely with contractors, developers, consulting engineers, and estate owners to provide dependable verification at every stage of the build. Our team is experienced in delivering surveys for both small private schemes and large-scale civil engineering projects, adapting our approach to meet the specific requirements of each site and each authority.
We regularly collaborate with drainage engineers, highway designers, and utility providers to ensure survey outputs align seamlessly with CCTV inspection data, design drawings, and adoption submission requirements.
As-Built Surveys are essential to confirm that the final constructed works match the design intent and comply with the tolerances required for adoption. Without accurate measured data, projects can face delays, refusals, costly rework, or disputes at the end of the job. By working with professional engineering surveyors, you gain clear evidence that roads, drainage networks, utilities, structures, and finished levels have been constructed correctly. This verification supports smooth handover, reduces risk, and helps ensure that assets can be safely and efficiently adopted by local authorities, water companies, or private management bodies.
For drainage adoption in particular, accurate topographical surveys combined with CCTV survey data are critical to demonstrate line, level, gradient, and connectivity compliance for S104 sewer adoption.
Since 1988, Kemp has delivered specialist engineering and verification surveys across the South West and throughout the UK. Over the decades, we have supported residential developers, civil engineering contractors, utility providers, and major infrastructure schemes with accurate As-Built and Adoption Survey data. Our experience extends from estate roads and S38/S278 works to S104 drainage, S185 diversions, public open spaces, retaining structures, and complex civil engineering installations. With thousands of completed surveys behind us, there is very little we haven’t verified.
This includes extensive experience supporting S104 sewer adoption using coordinated topographical and CCTV survey information, as well as highway adoption and improvement schemes requiring precise as-built verification.
Our process begins with a detailed initial consultation where we review all relevant design drawings, technical specifications, and the adoption criteria that apply to your project. During this stage, we also confirm the specific standards required by the adopting authority, whether that’s S104 drainage, S38 or S278 highways, S185 diversions, or private estate adoption, so that we can tailor the survey outputs precisely to their expectations.
Once the scope is agreed, our surveyors visit the site to collect high-accuracy measurements using the latest total stations, GPS equipment, and laser scanning technology where needed. During this stage, we capture all relevant features including utilities, drainage systems, roads, kerbs, structures, boundaries, and finished levels, ensuring every element of the constructed works is recorded with precision.
Before any detailed data collection begins, we verify or establish survey control across the site. This ensures that all measurements are tied to a consistent, reliable framework, allowing us to produce repeatable and dependable results throughout the project.
After the fieldwork is complete, we extract and process the survey data, comparing the as-built positions and levels against the approved design. Our team prepares CAD, GIS, or BIM outputs in the exact format required by the adopting authority or design team, ensuring that the finished information is clear, compliant, and ready for submission.
The final deliverables are produced as fully annotated survey drawings, digital models, or structured data packages that clearly show the constructed works and any deviations from the design. These outputs are formatted to meet adoption requirements, making them straightforward for authorities to review and sign off.
We continue to support the project for as long as needed, carrying out periodic verification surveys as works progress or as changes occur on site. This ensures that adoption submissions stay up to date, helping to keep the handover process moving forward without unnecessary delays.
Before any survey is issued, it undergoes a thorough internal review to confirm accuracy, clarity, and compliance with the relevant standards. All work is carried out in line with our ISO 9001 quality management procedures, giving you confidence that every deliverable meets the highest professional standard.
Our surveyors operate daily across Cornwall, Devon, Somerset, and Dorset, and we regularly travel beyond the South West to support clients with specialist or ongoing requirements. Whether you need a single verification survey or a complete adoption-ready package across a large development, we can mobilise quickly and provide the support your project needs.
At Kemp, we take a flexible and practical approach to As-Built and Adoption Surveys. We can provide anything from a one-off site visit to full project-wide verification and adoption support. Our team uses advanced GPS, total stations, digital modelling tools, and laser scanning to ensure that every measurement is dependable. With decades of successful approvals from councils, water authorities, and asset owners, we understand precisely what each body expects, and we deliver data in a format that meets their standards. This accuracy helps avoid delays and prevents costly rework during the final stages of a project.
Our ability to integrate topographical survey data with CCTV drainage inspections for S104 sewer adoption, alongside highway adoption and improvement requirements, sets us apart as a trusted technical partner rather than just a survey provider.
An As-Built Survey is a measured record of the works that have been constructed on site, verifying how they compare to the approved design.
Adoption authorities require accurate, compliant survey data before they will formally accept drainage, highways, or utilities. Without this information, the adoption process cannot progress.
We use total stations, GPS, laser scanning, and digital modelling tools to produce highly accurate data and clear, professional drawings.
Yes. We have extensive experience working on large-scale drainage networks, highways schemes, utility diversions, and complex civil engineering projects.
Absolutely. We deliver survey outputs in whichever format your design team or authority requires.
Yes. We regularly support S104 sewer adoption by providing accurate topographical surveys that align with CCTV drainage inspection data, ensuring full compliance with water authority requirements.
