Contract Period: October 2018 – January 2019.

Continuing our successful relationship ROPETECH were re-engaged by Story Contracting to carry out specialist geotechnical subcontract works.

ROPETECH’s work scope included:

  • De-vegetation and scaling of 8,640m2 of the rail cutting utilising roped access techniques due to the gradient. Works included the felling of mature tree’s up to 200mm diameter.
  • Installation of 160 number rock anchors to the crest and toe varying in depth from 4 meters to 6 meters and grouting of anchors with OPC grout.
  • Installation of 6,640m2 of double twist hexagonal mesh.

ROPETECH’s method of working:

Works were carried out using various techniques including:

  •  Installation of anchors by utilising Ripamonti EX170TH rotary percussion drills along with hand drilling via roped access.
  • Utilisation of track mounted compressors at the work face due to access constraints and a requirement to minimise impact on the adjoining land.
  • Works were undertaken during line blocks, possessions and open line.

Summary: All of ROPETECH’s work was completed safely, within budget and within the programme duration. 3,500 man hours were completed by ROPETECH onsite without any issues or lost time. By working closely with the Principal Contractor and resolving potential issues at site level there were zero variations raised which further cemented our relationship as a trusted supplier.

ROPETECH demonstrated their commitment to quality, safety and ecological matters by utilising equipment which has been specially commissioned by us to ensure we can deliver the most challenging of schemes.
