Services
We carry out accurate topographical surveys to support building development, land management, and design projects. By recording land levels and site features in their true positions, we help clients make informed decisions during the planning process. Our surveyors use professional Leica total stations and are trained across all aspects of land surveying and site setting out. We also maintain current industry certifications required for secure site access. 
We deliver comprehensive measured building survey services designed to meet RICS requirements. Using advanced equipment, we capture accurate building data to produce floor plans, elevations, sections, and CAD plans. We work closely with architects and large developers across residential and commercial projects. All survey data is provided in digital formats including DWG, DXF, and PDF. Our approach ensures dependable documentation for planning and design purposes. 
Our CCTV drainage surveys are undertaken across London and surrounding counties with consistent professional standards. We produce detailed sewer condition reports supported by precise inspection data. Specialist surveyors evaluate underground drainage systems to identify structure, flow direction and pipe dimensions. All results are documented clearly to reflect the condition of each surveyed system. 
PAS128 GPRS surveys are produced by Cadmap Limited for clients from homeowners to blue chip. A GPR survey is a non-invasive technique to identify and map underground features. Radar pulses are transmitted into ground and reflected by electrical property variations. Data is processed into images and 3D maps providing outputs for construction, utilities, archaeology and drainage. 
Cadmap Ltd provides professional boundary surveys for clients requiring accurate land delineation. These surveys depend on experienced surveyors and specialist instruments, as tape and handheld devices alone cannot deliver the required precision. We undertake work for boundary disputes, registration with the Land Registry, and accurate measurement of land areas. Our deliverables include structured reports and supporting boundary plans. 
We process point cloud data using Leica Cyclone software for registration and editing. Unwanted elements such as trees are removed and building sections created. Data is then imported into Leica Cloudworx for AutoCAD 2016 for drawing production. Outputs may be visualised using Revit and 3DS Max.

We used CADMAP Limited for a combination of topographical and utility surveys on a complex development site, and the service was excellent from start to finish. The team was professional, responsive, and clearly very experienced in handling detailed survey requirements.
The deliverables were highly accurate and well presented, including clear AutoCAD drawings and comprehensive utility mapping that made coordination with our design team straightforward. Communication throughout the project was consistent, and any queries were dealt with quickly and efficiently.
Overall, CADMAP provided a reliable and high-quality service, and I would have no hesitation in recommending them for topographical, measured building, or PAS 128 utility surveys.
