LeeMcCullough - Saint Nathy's Cathedral

By: Leemccullough  05/12/2011
Keywords: structural engineering, Condition Report, Engineering Issues

Project in brief
Saint Nathy's Cathedral was built circa 1855-1860, and the Clock Tower and Spire were added circa 1909. The famous nine-bell carillon was commissioned from Gillett & Johnson of Croydon, and the bourdon is dated 1905.

Routine inspection by cathedral staff suggested that the bell supports and fixings were seriously corroded. Our brief was to visually inspect the bell supports and fixings within the spire and report on their condition (listing structural defects, probable causes, and recommendations for remedial work).

Historical Renovation

At LeeMcCullough we have exceptional experience of revitalising existing buildings, which is often more complex than the structural engineering of new buildings.

Over many projects we have addressed and resolved a wide range of issues, including:

  • Strengthening historical joists and beams to carry increased loading
  • Masonry Decay/Delamination
  • Threading modern services into old structures

At LeeMcCullough we always seek to identify and resolve issues early, innovatively address demanding building difficulties and deliver our solutions on time and cost efficiently.

When it comes to renovation and refurbishment, anticipating and resolving engineering issues effectively is the key to a successful outcome.

LeeMcCullough - Fire Damage

Whether a fire damaged structure is a historic building or a modern construction, the ability of the Engineer to judge the extent of damage to structural elements can mean the difference between demolition and practical reuse-if repair and reuse can be justified, considerable savings can accrue.
