For onshore cranes at construction yards and quayside, below points to be considered in addition to the above. 1) Calculations in choosing the Appropriate Mat Size to be provided and to specify the Mat’s Material (Wooden, Steel or Concrete). 2) Site Ultimate Ground Bearing Pressure report to be provided for review. 3) All Four Outriggers / Crawler Tracks Pressure on Ground (under Worst Case Scenario) to be calculated using Crane Manufactures Software or Manually using the method specified in UK NCC (National Construction College) “{(Crane Weight + Additional Counter Weight) x 0.75 + Load Weight}/Outrigger Area. 4) Ultimate Ground Bearing Pressure should be more than Outrigger / Crawler Tracks Pressure on Ground after adding a Minimum Safety Factor of 1.5 in case using Crane’s Manufacture’s Software (The factor of 1.5 is the absolute minimum, shall be used only under the guidance of an experienced geotechnical engineer) and a Minimum Safety Factor of 2 in case of Manual Calculation. 5) Ground Foundation type to be mentioned. 6) The Mat can be calculated using the method specified in UK NCC (National Construction College) “{(Crane Weight + Additional Counter Weight) x 0.75 + Load Weight}/Ultimate Ground Bearing Pressure; then lifting a load equal to Counterweight and swing it over each Outrigger to check if it is sink then a larger Mat to be used. 7) Safe Distance between the outriggers / Crawler tracks and the end of the jetty to be provided and approved by Structural Engineer.
