Having been in business since 1955, SteelFab, Inc. has worked with numerous outside detailing firms over the years, but none more professional than our experiences to date with 4D Steel Detailing. I have been very impressed with their sense of urgency and acute attention to detail and have the utmost confidence in their ability to detail structural steel per the architect and engineer?s design intent, and within the codes of the A.I.S.C., and our shop standard practices. I personally have enjoyed the relationship formed with Paul Symes, Gary Fohl and Bill Worsham PE, during the course of our latest project with 4D, the Jacksonville, FL Ballpark for the Los Angeles Dodgers AA affiliate. Their ability to promptly issue and track up to fifty (50) RFI?s on this very complex project and still maintain our original detailing submittal schedule has made my job as a Project Manager much easier. Paul Symes, Gary Fohl and Bill Worsham, PE are all men of high integrity and professionalism, who take their job very seriously and meet all of the commitments that we have promised our customers. Please accept this recommendation from the SteelFab, Inc. companies for the prospective membership of 4D Steel Detailing into the N.I.S.D. Stuart R.
