Our firm performed an inspection and analysis of an existing suspension bridge crossing the 'Cross River' between Cameroon and Nigeria. The bridge was designed in the 1940s by a British company and was completed in the early 1950s. Once the original drawings were located in an archive in the
U.K. a team was established to examine the existing bridge. The bridge was surveyed and all information collected in the field and archives was processed in the office for a detailed review report including the status of all the elements including ranking and identifying major defects. A full model of the bridge was computerized based on the findings and calculated for both the original and up to date loads in order to examine the capacity of the bridge members and the global stability. From the information collected and calculated, the recommendation was to preserve the bridge as a unique element in Nigeria's heritage.
