Our Site Engineers deliver a comprehensive suite of As-Built Surveys, tailored to the unique requirements of each project.
No matter what stage you’re at, you’ll be able to retrace your steps by following a trail of detailed drawings and highly accurate data that’s clearly visualised.
Whether capturing the precise geometry of newly constructed structures, mapping utilities as installed, validating levels, or documenting the final position of highways, we utilise state-of-the-art surveying equipment and digital workflows to ensure accuracy and clarity.
We produce as-built information in a wide range of formats to suit your needs, from traditional 2D plans and annotated CAD drawings to rich 3D models such as isopachytes. These contour maps illustrate height variations across a slab or site, enabling clear visualisation of material layers or changes in level.
Data can be supplied in industry-standard formats, including PDF, DWG, and DXF, allowing seamless integration with BIM platforms and project management systems.
What We Can Help With
We tailor our deliverables to support your project’s design, compliance, and data management requirements, ensuring that your as-built records are not only thorough but also immediately practical and actionable.
Our As-Installed or As-Built Surveys typically cover, but aren’t limited to:
Whether you’re the main contractor, a client looking to verify completed works, or a specialist subcontractor needing a ‘sense check’ when inheriting work on a project, we’re here to help. Get in touch today for more information on our As Built Survey services, or for a quotation.

Meet Tolerances Early On
If you’re in the early construction stages of your project, commissioning an as-built survey will ensure that level and positional tolerances are being met. This applies to all elements involved in your project.
Accurate as-built surveys serve as a reference point to compare ongoing construction to the original designs. At SEP Engineers, we work closely with architects and designers to keep your project on track and prevent costly mistakes.
Regular Verification Checks
Verifying setting out information is essential at every point in the construction phase of your project, which can be delivered through accurate and transparent As-Built Surveying data.
Our team can integrate your as-built data with Building Information Modelling (BIM) systems for more effective project management.
Your report will contain a host of visualisation findings, such as colour-coded deviation maps, which can be included within quality control records.
