About this file
This document package includes an engineering letter and shop drawings submitted in response to a solicitation for tactical infrastructure maintenance and repair services within the Tucson Sector for U.S. Customs and Border Protection. The engineering firm analyzed retrofitting gate designs at three locations to remove old gate track and trolley systems and install new high-motion systems, finding the new configuration would see equal or less stress and deflection than the existing design under equivalent loads. The shop drawings provide details on installing overhead beams, track, wheel truck brackets, and hangers to complete the retrofits. The related solicitation seeks maintenance, repair, and improvement services for tactical infrastructure assets including roads, bridges, fences, gates, vegetation control, debris removal, lighting, drainage, and tunnel remediation. Responses are due by February 25, 2021 for an optional site visit.

RE: Gate Retrofit Design for
Yarbrough Gate
CC Bills Gate
Gate East of Fabens POE Gate
Dear Mr. Sloan
You requested that I analyze the gate retrofit design for the 3 El Paso Sector gates in order to verify that the removal of the old gate track and trolley system and installation of the new Hi Motions system (that Sloan has used in the previous K-2C project) would not adversely impact the strength of the existing and remaining structure. I did this by creating 3 dimensional models for the critical structures of both the existing configuration and of the proposed design. Information on the existing design was supplied by Sloan Security group in the form of as-built drawings and pictures. It is important to note that the scope of this analysis did not include footing and foundation design, only the above-ground steel framework at the gate opening and back-track areas. I then applied Finite Element Analysis to these models in order to calculate and compare relative stresses and deflections of the two configurations. The models were virtually loaded using the same conditions and assumptions from the previous Sloan K-2C project and that baseline was used for comparison. The approach was also conservative in that the models were loaded with the worst case assumption that the track adds no strength or rigidity to the system. We know that in reality, the new Hi Motions steel track has much more section and strength than the existing aluminum track. Hand calculations were also used to validate the FEA results.
Results showed that the new configuration (retrofit design) will see equal to, or less than, the same stress and deflection values that the current system, for equivalent vertical, lateral and combined loads. Therefore, there should be no detrimental strength or deflection issues experienced with the new retrofit gate design relative to the existing design. The attached sheets show FEA comparisons of the two configurations for stress and deflection. Please feel free to contact me if you have any additional questions regarding this analysis.
Regards, Michael J. Witt, P.E.
