RE: 61 BROADWAY STRUCTURAL INSPECTION • T-T I'TtO&CT NO.: 21689

Dear Kevin: building at A team of Tlhomton-Tomasetti Engineers performed a visu it inspection.of the impact of 61 Broadway. The purpose of this inspection was to Clete -mine the structural the World Trade Center disaster on the primary structure 01 ()1 Broadway.

The team consisted of Paul Lew, P.E. and Christian 13eimp' e, Engineer.

The inspection included the basement and the roof. ' '.'he Moors' listed below were inspected as well as the basement and roof The inspect A' floors were as follows: 33, 31, 27, 23, 22, 19, 16, 14, ii, 8, 5 and 2 as well as the Iobb" and subway level. more A xnoxc'for )al.report will follow but this letter surnrnariz..:a the conclusions of the formal report to follow.' The report is limited to the prima, y structure; and does not make. any statement as to the interior ftnislles or ceilings ilia are .not . of the primary pat

structure.

visual structural inspection did not indicate that there were any signs of strocti*rally unsafe conditions in the btiil.dir}g. There .is some very united minor cracking in the Our

basement walls but these cracks appear to be pre-existi :'mg and not impacting on the structural integrity of the building. We have reached I tie conclusion . that. the minor cracking is pre-existing and not structural, in part, because there weie no noticeable signs of paint or plaster having fallen at the locations of cracking . or any other signs of diafress. • plaster and paint would typically occur if the crack had rec :ntly. occurred. The inspection , included inspecting the brick facade around the courtyan looking for cracks .at various levels in the brick. No cracks were found although there 1, as been previous repairs to the facade as would be expected of a building of this ago.

Based on these visual observations, the building is not in.s'i nictural distress at the present
