    • Dilapidation survey - poor condition of the building. Building diagnoses - leakage, watermarks, termite infestations, rising damp, salt contamination, organic growth and water seepage. During the Detailed investigation - the removal of the panels had further discovered similar problems affecting the structures behind the panels as shown in Photos 2 and 3. Consequently, an extensive restoration work was proposed for the Old City Hall in order to rectify the serious building defects. CONT’
