BAB Mechanical Services, Inc. Non payment of Services New Hyde Park NY

Services rendered were not approved by the Engineer or GC and needed to be corrected for final approval.  The plank shop drawings needed to be completly redone.  They were done to the wrong scale and information transfered for each opening was not correct for the actual openings required on the riser drawings.  We were left with unapproved shop drawings and incorrect plank shop drawings.  All PDF drawings had to be transfered to CAD format drawings at additional costs for corrections.   We pay our bills on correct and completed work.
