Topographical Surveys

A topographical survey may be commissioned for a variety of reasons and is an imperative part to the start of any project.

Traditionally, land developers, architects and planning consultancies utilise this type of survey to enable them to design projects using the most accurate of data.

At ZS Surveys, we have a team of surveyors with extensive experience in all types of projects. Our team can advise on the most effective way to conduct your survey which still delivers accurate, efficient, and quality data but will, also, save you time and money.

ZS Surveys are highly regarded within the building sector for fair pricing and efficient, quality data.

    Types of Topographical Survey

    Topographical surveys are all generally the same involving the detailed collection of position and height and position of features using a GPS or Total Station.

    Sometimes there are challenges that require something special to enable the collection of information.

    Some of these can include:

    • Drone Surveys – including LIDAR

    • Bathymetric Surveys – obtaining information under water

    • Mobile Mapping – vehicle mounted scanning station for large areas of road

    • Laser Scanning – creating a 3D model and extracting the information from this

    Frequently Asked Questions

    What is a Topographical Survey?2023-11-24T15:59:21+00:00

    Basically put a topographical survey (topo) is a highly detailed map of the area of interest.

    But this isn’t any type of map. This is a detailed drawing indicating the detailed height and position of features, to enable a highly accurate design or model of the area.

    Some of the features that are commonly surveyed are kerb and feature lines, buildings, utility covers, manhole and drainage information, trees and general ground levels.

    All of this information allows us to create a 3D model that can be used when designing on or altering land.

    Our surveyors use an array of different techniques to ensure that all the information that is obtained is accurate and relevant to your projects.

    Our standard practice is to use a total station to capture the majority of the information required. This is complimented with the GPS equipment to ensure that all areas are covered and also coordinated to the OS network. This means your data isn’t just relevant, it’s the correct height above sea level and in the correct location in the country.

    There are various other ways we can obtain information. Why not give us a call to chat?

    Why do people need Topographical Surveys?2023-11-24T16:02:21+00:00

    There are a lot of instances where a topographical survey isn’t used in the design process.

    The issues that can be introduced will only be discovered during construction. This then becomes costly if you are the bill payer.

    Having a highly accurate topographical survey is the foundation to a successful project.

    From a small extension to a cross country rail track, all projects will benefit from a highly accurate survey carried out by a competent team of surveyors.

    Some of the benefits that we have seen professionally in the 20 years we have been in the industry are:

    • A quicker design period
    • More accurate design
    • Planning of a more efficient build
    • Less waste
    • More accurate costings from builders
    • Accurate cut and fill volumes (less waste)
    • Quicker build time
    • Less down time

    Ultimately the initial cost of a topographical survey could save you thousands in the correct design and planning.

    How much does a Topographical Survey cost?2023-11-24T16:04:46+00:00

    This all depends on the size of the area and the output you are requiring.

    All surveys are different and require different detailing.

    So the length of time on site can vary which will impact the cost.

    But essentially, we will cater for your budget and your needs and will be honest and open with the possibilities and costs.

    How long does a Topographical Survey take?2023-11-24T16:06:39+00:00

    This can vary but is usually dependent on the size and scale of the site.

    As no site is the same, and no planning application is the same, attributing a time scale to a topographical survey can only be done once we know the size and need of the survey.

    What equipment is used in a Topographical Survey?2023-11-24T16:08:16+00:00

    There are various different types of equipment that can be used to conduct a topographical survey.

    The main aim of a topographical survey is to obtain measurements to accurately map areas.

    The measurements can be taken in the form of angular and linear measurements, raw coordinate collection and laser scan data.

    Generally, the items we use to conduct our topographical surveys are:

    • Total Station
    • GPS receivers
    • Drone
    • 3D Laser Scanners
    • Laptops (N4ce and CAD)
    How accurate is a Topographical Survey?2023-11-24T16:09:28+00:00

    Generally, with topographical information that is obtained, you could expect an accuracy upto 5mm.

    So, rest assured that accuracy is to the forefront of our minds.

    What qualifications do our surveyors have?2023-11-24T16:10:41+00:00

    All our surveyors hold a minimum of a TSA or HNC.

    Within our ranks of surveyors, we have TSA qualified surveyors and also degree qualified engineers.

    So, please rest assured that we have the best surveyors in the country.

    What does the customer receive after a Topographical Survey?2023-11-24T16:12:06+00:00

    Once your site work is complete, we will conduct a series of data processes to ensure that your topographical data is as accurate as possible.

    Once this is complete, we will start the data processing.

    Depending on your requirements, we can provide specific files.

    However, our main data format would come in the form of a PDF and CAD file (.pdf/.dwg)
