As a subconsultant, SI Engineering, P.C. (SIE) performed the inspection of tunnels E, F, A Brick and the 15th Street Drift including the North and South Projections and Emergency Exit Stairs at WTC connecting Hoboken and midtown Manhattan. SIE performed condition surveys and structural inspections of the PATH tunnels to ensure safe operations. Visual and hands-on inspections were conducted to identify potential problems in the tunnels. The assignment also required monitoring of structural elements and documentation of the various forms of deterioration. SIE was also responsible for preparing a Condition Survey Report upon completion of the inspection. The Report included overall rating, increase or decrease in number of priority repairs, and all other pertinent information gathered from the inspection, as well as color photographs of significant elements, complete deficiency location plans, and prioritization of conceptual recommendations for any rehabilitation or repairs.
