We are in process of installing a turbine skid on metal frame which has 3 mounting pads. Each pad is about 1 meter x 0.5 meter size. Manufacturer has specified following requirements for the mounting pads. "Each foundation pad or Sole Plate should be installed flat within 0.030”/ft (2.5 mm/m) and coplanar to 0.120” (3.0 mm) to the other pads.
Manufacturer field rep. inspected pad and found that surface of pad is not flat as required 0.03"/feet. Construction contractor is arguing that it is flat as per 2.5mm/meter requirement specified in metric unit and imperial unit 0.030"/feet is not same as metric unit 2.5 mm/meter for flatness. Can any one provide more information on how to interpret flatness for rectangular pad specified in inch/feet or mm /meter and what is the best way to carry out field measurement? Is 0.030 in/ft (0.025 mm/cm) can be considered same as 0.030”/ft ([highlight #FCE94F]2.5 mm/m[/highlight]) for this purpose?
