Investigation Survey Information SheetTo support the design of our flood risk management scheme (FRMS) in Kendal, we need to undertake various surveys from taking measurements to identifying local features and utilities. All of our surveyors are fully qualified and experienced at undertaking this work.

Below we have provided information about how these surveys will be undertaken.

Topographical SurveyA topographical survey is a survey of the land to identify features. GPS (Global Positioning System) equipment and Robotic Total Stations are used to locate points. These points are then shown as a three dimensional display of all features including the property, land features and physical boundary details on a scaled survey drawing.

This plotted drawing will help the design of the scheme by providing a clear display of the site constraints and opportunities.

Utilities/Ground Penetrating Radar (GPR) SurveyA Ground Penetrating Radar (GPR) survey is one method used in archaeological geophysics and utility service mapping. GPR is used to detect and map services and underground features using a non-destructive technique. An example of the equipment used is shown by the image to the right. The unit sends radio signals through the ground and detects the reflected signals coming back to the unit. The unit interprets the signals to give interpret the depth and measurements of any underground features.

The unit also records information using GPS, which enables an accurate plotted drawing to be produced. Any services or underground features encountered may be marked on site.

Trial Pit SurveyTrial pitting is a method used to physically identify known utility services, ground conditions or underground features and take material samples. Trial pits involve digging a localised area, usually undertaken by hand in many cases but for larger trial pits, a mechanical excavator would be used. The common size for trial pits are around 1.2m long by 0.6m wide to a depth of 1.2m.

FAQs

Q - What time will the operation be undertaken?A - The works will be completed from 8.30am until 4.30pm

Q - Are there any risks to my property?A - There is no risk to property and Investigation Works are located to ensure that information is gained without need for interface with properties

Q - How will my property/garden be left?A - Prior to any works being undertaken there will a photographic survey taken. On completion of the works, the garden/property will be reinstated to its original state. There are no foreseeable works that will damage property.

Q - How many people will there be on my property?A - This will vary but there will be two operatives, one supervisor and one specialist on or around site at all times.

Q - Will the activity be noisy?A – There will be only noise generated by plant for breaking tarmac for the trial pits planned. The trial pits are dug by hand, so no mechanical plant will be used to excavate, but the breaking of the hard surface and reinstating will create the noise. The noise will be monitored throughout and if there is a need for acoustic barriers to reduce any residual noise, this will be put into place.

Q - How long will you take to complete this work?A - The Survey and Investigation Works throughout the Kendal area are planned until March 2020. There are 38 trial pits to be completed. It is assumed that providing there are no obstructions, the operatives and equipment should be on your property for no more than 5 days.
