The TopoCrew Advantage
A high-quality topographical survey will minimise site issues and set your project on a path towards success. A reliable survey is crucial to ensuring that your budget forecasting and estimates are as precise as possible. It guarantees that your 2D and 3D design is appropriate for its intended purpose, and can assist with various tasks such as bill of quantities, traffic management and consultation.
IMPORTANCE OF A RELIABLE TOPOGRAPHICAL SURVEY
A poor topographical survey can leave a scheme in trouble, requiring additional work from design teams and leading to unexpected design cost. Incorrect designs due to bad surveys can be financially draining when construction begins. Flawed surveys can cause issues for designers and contractors and result in a design/build working style that can wreak havoc on programmes and finances, especially if utility issues arise.
PROBLEMS WITH POOR TOPOGRAPHICAL SURVEYS
TopoCrew delivers topographical surveys that are tailored to meet your project's specific needs. Our approach combines the use of advanced technology, such as laser scanners and robotic totalstations, with a deep understanding of the design process. This enables us to provide comprehensive, accurate surveys that are crucial for your project's successful planning and execution. We focus on quality while minimising errors, helping you eliminate unforeseen costs and delays. Our commitment to precision and client satisfaction is evident in every survey we conduct.
Superior Layer Structure
We segregate 2D and 3D elements and allocate each survey component to a layer structure. This gives designers a remarkable opportunity to use the survey in all aspects of their design. It significantly speeds up the conversion of survey data into design information, including construction packages and stakeholder information. Overall design costs are reduced and designers can better present information to contractors.
All Important Aspects Are Surveyed
Nothing important is left out - before issuing any drawing, we conduct a thorough on-site verification, during which our surveyors meticulously compare the site with the drawings to ensure that nothing is omitted, particularly looking out for any missing objects.
Rigorous Data Collection with Modern Instruments
We establish a control network using robotic total stations and create a rigorous survey framework by adjusting the survey results with Microsurvey STAR*NET. The resulting high-accuracy network of reference points forms the basis for the detailed survey, which is carried out using robotic total stations or, increasingly, laser scanners. Laser scanners are highly efficient, greatly reducing our time spent on site.
What Sets Our Surveys Apart
“The quality of the TopoCrew’s surveys have been excellent and has resulted in reduced number of site visits required to verify data or collect missing data and has greatly increased confidence in the designs prepared. Working with a surveyor who provides such high quality work with excellent customer service was an obvious choice.”
Simon Gibbs
Director, Roadways Consulting Ltd.
“TS Nexus have worked with TopoCrew on numerous projects over the past 10 years. From topographical surveys for design purposes to as built surveys their attention to detail is second to none. Their accuracy has been crucial during design stages and their attention to detail during setting out has been vital on numerous schemes including Aldgate for the City of London. A fantastic survey company.”
Simon Rollinson
Director, TS Nexus Ltd
“Having used their topographical survey services for almost ten years, I have come to trust that I will always receive a quick, friendly and very efficient service. No matter the size of the task or its urgency, TopoCrew always manages to deliver quality work at a fair price.”

WHY CLIENTS CHOOSE US
Our phased approach is optimised for accurate measurements, quality and efficiency. From a thorough initial site assessment to the final issue of drawings, each phase has clearly defined milestones and deadlines to ensure timely execution.
Quality checks are integrated at every step, guaranteeing the highest level of accuracy. This allows us to deliver extremely reliable topographic surveys that meet your specific project's needs within the agreed-upon timeline.
-
PLANNING: We notify you of the exact start and expected delivery dates
-
PREPARATION: We conduct the necessary searches to prepare for first site visit. We will locate nearest Ordinance Survey Benchmark, obtain OS base map, assess site safety, conduct Risk Assessment and Method Statement
-
NETWORK DEVELOPMENT: Our surveyors establish the reference control network by marking control points and surveying their positions with high precision RTK GNSS receivers and Leica Geosystems total stations
-

Project Plan and Delivery
Laser scanning has revolutionised the field of land surveying. It enables us to plan and execute projects more efficiently, and our customers to analyze every component of any facility or site. In addition to conventional 2D and 3D CAD drawings, a wide range of further deliverables can be easily produced. Panoramic photographs are also taken during scanning, and a detailed 3D digital model is created giving you better construction and design possibilities.
Maximum Accuracy and Confidence in Your Data
Laser scanning surveys generate an extremely high-density point cloud with sub 5mm level accuracy, giving you confidence in every decision you make from the survey results. You can easily detect fine deformations in buildings and roads, assess road conditions, develop informed and well-considered design plans, create proactive maintenance plans to ensure safety and longevity, and much more.
Easily Explore and Use Your Point Cloud
You can view and navigate your scanned point cloud in 3D similarly to Google Street View. This transforms your data into intelligent virtual spaces, enabling smart collaboration and decision making from anywhere. You can measure distances and areas; create and share notes with colleagues, and more.
Complete Your Projects More Efficiently
Using laser scanners significantly reduces the time spent on site, yet more data is collected – including at ground level and from higher elevations. Facades of surrounding buildings are scanned, allowing for easy production of elevation drawings. The automated data capture minimises the potential for human error.

FEATURED CASE STUDIES
Topographical Surveys Highlight
We pay special attention and use rigorous quality controls to avoid problems commonly found in topographical surveys. This helps you prevent significant issues during the construction phase, including unexpected design costs and the repetition of work. Explore some of the errors we prevent:
Keep your projects free from errors, cost overruns and delays
An unstructured layer system in CAD drawings can make them very difficult to use. Mixing different types of objects on the same layer slows down work significantly.
We have been working with highway designers for over 10 years and developed a sophisticated, well-structured and very user-friendly layer system specifically for civil engineers. Individual objects can be easily found and separated with just a few clicks.
