An airport authority approached CALM Survey Solutions Ltd to assist in capturing asset data associated with a sewerage network within the confines of their site.

Issues identified were:

  • The depth of sewer was in the region of 26 metres.
  • The length between access chambers was approximately 250 metres.
  • The 450mm circular sewer was located and fixed to the side of a 1950mm storm water culvert.
  • No condition survey on the asset including its fixings had been carried out for many years.
  • Due to the depth and the siting of the sewer within a storm water culvert, health and safety complexities needed to be overcome.
  • The airport authority wished to host the asset data information in a system that was accessible to its personnel in different parts of the country.

What We Did

CALM Survey Solutions Ltd met with the airport authority on site to gather and obtain as much information as possible:

  • A meeting took place with the principal contractor with the objective of gathering as much information relating to the sewers and area.
  • Plans and sections were obtained. With these a pre-survey health and safety plan, including risk assessments and method statements, were compiled.
  • Following detailed discussions with the Client, bespoke site data forms were developed, so that condition information along the length of the sewer could be gathered. The form incorporated photographic records.
  • It was decided to undertake a survey on one 250 metre section of main in the first instance. Once the information retrieval had been completed and held within AIMS, all parties could look at the information and make considered and necessary changes, prior to surveying subsequent section of sewer.
  • AIMS captured the chamber details, which included 3D drawings.
  • Using sub metre accuracy GPS devices the location of the chambers was recorded.

The Results

  • AIMS was developed to include a bespoke survey capture form to gather the information.
  • The works was undertaken and the information gathered, greatly assisted the Client. The information provided allowed the Client to determine repair work necessary and compile not only a remedial programme of works, but also a detailed bill of quantities for estimating purposes.
  • Effective and good communications played a critical role in the schemes success.
  • Asset condition reporting including health and safety, condition and serviceability.
  • AIMS cloud based data management system hosted the information coming back in from site.
  • 3D drawings generated from the site data.
  • A “Facebook” header page for each asset including location and condition detail.
  • Site data automatically extracted, uploaded to the system and graded to give an accurate assessment of the assets condition.

As a consequence of the success of this project, further discussions are in progress to undertake more works for the Client.
