We will work safely or not at all


What we do40Seven is dedicated towards providing comprehensive and accurate topographical surveys to a range of high profile clients.

There are many reasons why a topographical survey will be required, but typically they are used by architects, planners and engineers for the design and planning stages of a project. Whatever the project that you are considering, a thorough and accurate survey drawing will reduce the risk of costly downstream mistakes caused by unforeseen issues.

How we do itBy utilising the very latest technology and experienced surveyors based throughout the country

We use a combination of Reflector-less and Robotic Total Stations in conjunction with high accuracy GPS systems and modern digital levels to ensure that all our surveys meet the prescribed standards.

Typical Topographical surveys that we carry out include:

  1. Global Positioning System (GPS) surveys
  2. Highway surveys
  3. Railway surveys
  4. Flood plain surveys
  5. Water treatment works
  6. Pipeline surveys
  7. Green/Brownfield Development sites

In essence, Engineering Surveying is the reverse of Land Surveying. It involves taking an engineer’s design drawing and accurately setting out the positions and levels of the required points of a construction project. An extremely high level of accuracy is required for construction projects and 40Seven use high specification Total Stations to ensure that all setting out work is carried out as accurately as possible.

Ideally, an accurate Topographical Survey of the site will have been carried out, upon which the design drawings will have been based. All the points to be set out will then have coordinates that relate to an existing network of coordinated stations which are already present on site. This enables the setting out work to be carried out accurately and efficiently with minimum set up time.

Construction projects that 40Seven currently provide Engineering services for are:

  1. Structural Piling.
  2. Cladding Systems.
  3. Curtain Walling.
  4. Buildings.
  5. Highways.
  6. Railways.

Due to the high accuracy required on Engineering projects 40Seven only use our most experienced surveyors for carrying out these works. The ability of the surveyor to read and work with engineer’s drawings is key to the success of the project. All site works are fully checked on site and records are kept by surveying the marked out points once they have been set out.
