Subgrade failure had compromised an existing retaining wall, creating a safety risk that required full demolition and replacement. Working inside a high-security correctional centre meant strict compliance with cleared personnel, tool control and live site access management, without disrupting centre operations or emergency access routes.
Solve Civil surveyed the site with GPS equipment and worked with Woolacotts Consulting Engineers to design a 2.3 m high core-grouted block retaining wall with integrated drainage and temporary shoring. Solve Civil also delivered three additional items at no cost to the client: safety handrailing on an adjacent wall, relocation of five AC units to high wall mounts, and re-routing of surface stormwater pipes to remove slip hazards.
The new wall restored structural integrity, with works staged and existing services protected throughout. All works followed correctional centre security protocols and Solve Civil’s ISO 9001 and ISO 45001 certified management systems, and centre operations continued without downtime.
