​As part of Network Rail’s 2017/18 programme to carry out repairs and refurbishment of existing structures, MHB Consultants Ltd. was appointed as designer by Taziker Industrial to undertake the engineering design of the works on UB 162/051 River Ayr Viaduct, which crosses River Ayr in Ayr town centre.
 
The works included undertaking condition surveys of the existing cast iron walkway and masonry before developing repairs to both.  To assist in determining repairs for the walkway, MHB Consultants undertook 3D finite element analysis to determine extents of metalwork repairs, designed the replacement concrete deck units and assisted Taziker Industrial in developing a safe construction methodology to implement the repairs.
 
All works were carried out without the need for disruption to rail traffic.
