"on Time & Budget"

  • means that a fabrication date will be provided to the client that is based on our suppliers delivery dates over which Guardian has no control and/or,
  • when the suppliers materials are delivered they are also subject to review, approval by Guardian prior to fabrication,
  • in the case of steel it is subject to mill tests reports being in conformance, approval by Guardian and its third party engineer prior to fabrication, 
  • if the materials or material test reports  are found to be defective,  then delays beyond the control of Guardian will more than likely result and corrective steps will be taken to conform to the design stamped shop drawings
