BAPS Shri Swaminarayan Mandir Temple

For many centuries, Hindu temples have been designed and constructed with the techniques outlined in the Shipla Shastras texts. In keeping with the ancient temple design, the BAPS Shri Swaminarayan Mandir structure uses unreinforced masonry construction with no structural iron or steel reinforcement. Unlike other similar Hindu temples, cracks were observed on the exterior marble beams which could affect structural integrity of the porticos. Walker was retained to investigate the cause of the cracks and to determine if the cracks affected the structural integrity of the beams. Walker utilized both non-destructive and destructive investigation techniques to assess the integrity of the beams.

Industrial Grain Silo

An industrial facility in southeastern United States, constructed in the mid-1970’s, was experiencing distress to its concrete façade. Concrete has spalled off, exposing reinforcing steel as well as a danger to the workers below. Walker worked as the Engineer with a Contractor to develop an appropriate repair approach that was implemented as a design-build solution. Walker’s role included preparing appropriate repair details and performing field visits and issuing field reports. One of the critical design elements was determining the maximum permissible opening size and work phasing so that the work could be done safely while the plant was operational.
